After hearing Yang Peng's words, Zha Yunke pondered for a while and said nothing. Yang Peng also wanted to run overseas. As a businessman, Zha Yunke didn't want a competitor to compete with him. One more competitor,
The purchase price of raw silk in Bianjing will be higher, the price in Japan will be lower, and Chayunke's profit will be reduced.
But Cha Yunke is not only a businessman, but also an official and businessman. The most important thing for an official and businessman is connections. Yang Peng is extremely powerful. Helping Yang Peng go overseas can earn Yang Peng a favor, which will have countless benefits in the future. For example,
The relationship between Cha Dengbei and Yang Peng seems not to be very good. I would like to do Yang Peng a favor, and it might be useful at critical times in the future. Cha Yunke weighed it again and again, and finally said: "Your Majesty, what these shipbuilders are doing is illegal."
Most people cannot inquire about their private shipbuilding. If ordinary people want to ask me about the shipbuilder, I will definitely not tell them. But since the Lord of the City has opened his mouth, I must help him."
Yang Peng smiled and said: "Master Cha is an interesting person!" Cha Yunke said: "I will bring the shipbuilder to see the Lord of the City tomorrow, and the Lord of the City will wait for me in the mansion." Yang Peng cupped his hands and said: "Then Yang
Peng is waiting at home for Young Master Cha." Early the next morning, Cha Yunke entered the Yang Mansion with three craftsmen wearing thick turbans. "The leader is Mr. Wang, the head shipbuilder of Wangjiawan."
Yang Peng looked at the leading craftsman and saw that he was short in stature and had dark skin and calluses on his hands. He looked like a fisherman. Yang Peng asked: "What kind of boat can you build?" That boss Wang seemed to have seen many big craftsmen.
The official did not flinch when he saw Yang Peng, the city lord, but said calmly: "Master Taibao, I can build a local pointed boat in Dagu. This boat has a sharper bow than a Fu boat and a flatter body than a Guang boat. It is especially suitable for traveling in the north.
The average pointed boat uses two thousand materials. The captain can be ten feet long, has three decks above the water, and the cabin is divided into about ten watertight cabins. It can sail to Japan. If you are brave, you can also sail to Nanyang.
As long as we don’t get caught in a hurricane, we’ll be fine.”
One foot in the Song Dynasty is similar to one foot in later generations, three feet is one meter, and ten feet is thirty meters. Yang Peng thought for a while and felt that the ship Wang Datou mentioned had a displacement of more than two hundred tons. Cha Yunke explained:
"Sir, the two thousand figures mentioned by Boss Wang are folk figures, which are different from official figures!" Yang Peng asked: "How much money does it cost to build such a ship?"
Boss Wang said: "It depends on what kind of boat you want to build! The wood used in shipbuilding may be good or bad, and it needs to be dried in the shade. The price of drying in the shade varies in different years. If you want to build a good ship, you need to repair it.
A ship that can last six or seven years requires 4,000 taels of silver, 602 fir logs, 298 miscellaneous logs, 40 individual logs, four elm rudder posts, and four chestnut logs.
, seventy-six scull blanks. If it is inferior, a bad boat that only lasts two or three years, the wood used is very different, and the joints do not need to be made of bamboo dipped in snakeskin paste, just nail them with iron nails.
The construction cost is two thousand taels and that’s enough!”
A good ship of more than two hundred tons costs four thousand taels of silver, which is not cheap. Yang Peng said: "What if I want to build a bigger ship? For example, build a big ship with four thousand materials." The craftsman looked at Yang
Peng said: "I can build it too, but it requires more labor. If you want to build a large ship with 4,000 materials that can last for six or seven years, it will cost about 10,000 taels of silver."
"How many months will it take to build two big ships costing 4,000 materials faster?" "The younger one called in all the craftsmen who are familiar with him nearby and can build them in five months." Yang Peng nodded and said:
"Do you know about ship ribs?" The craftsman was stunned for a moment, then thought about it and said, "I don't know."
Yang Peng said: "If I want to install a strong crossbow on the ship, I must lay wooden ribs on both sides of the keel for support. If you don't understand, I can teach you." Sea-going ships in the Song Dynasty generally used watertight cabin structures. This kind of ship structure
Technically very advanced, it allows the ship to still sail as a whole even if it is partially damaged. The deck of the watertight compartment can also provide lateral support for the ship. However, this support is relatively limited and cannot withstand the recoil of the strong crossbow. The recoil of the strong crossbow
The watertight compartment can be supported, but if you want to install a crossbow on the ship, you must lay the ship's ribs.
Yang Peng had learned about the structure of wooden sailing ship ribs before, and it came in handy at this time. With Yang Peng's knowledge and the experience of these old shipwrights, I believed that he would be able to build the ship's ribs. The Lord of the City did not expect this at the bow of the ship.
He also knows the technology of shipbuilding, but he is half-confident about it.
But Zha Yunke knew that Li Zhi was a skilled craftsman and that Yang Peng knew a lot about new things. He believed that the boat ribs Yang Peng mentioned must be useful new things. He said to Boss Wang: "Boss Wang, you are lucky. Help the city lord."
You can learn new skills in building ships, and you will make a lot of money this time!" Boss Wang scratched his head and said: "I really don't know what a ship rib is, and I need the city lord to give me some advice."
Yang Peng nodded and said: "Two large ships with four thousand materials cost twenty thousand taels of silver? Can it be cheaper?" Boss Wang said calmly: "Sir, all we earn is craft money, and we use enough materials.
As much money as we have, we can buy as much material as we need to build a bigger boat. If adults give us less money, we will have to buy less materials to make smaller boats, or if we buy inferior materials, the boats will not be able to be used for so many years.
"You can give me as much money as you want, but the final boat will be different."
Cha Yunke also said: "Don't worry, sir. These shipwrights are all craftsmen. They just make a living for their craftsmanship and will not be greedy for Lord Mo's money. He also built my ship, and I have repaired it with him every year these years."
, the money spent is all worth it." Yang Peng thought for a while, nodded and said: "Okay, I believe you, I will give you 10,000 taels first to buy wood for you, but I have to send someone to go with you.
Procurement, registration and accounting. After the wood arrives, I will teach you how to make ribs. In addition, I will also build two paddle wheels, and I will teach you together then."
Boss Wang said: "Okay! Don't worry, sir, you have invested so much money. I will definitely buy the best materials to ensure that your boat can be used for seven or eight years!" Yang Peng smiled and nodded.
The shipbuilding cost of 20,000 taels was not a small figure. Yang Peng wanted to send someone to supervise the cost of the boatmen, so he sent Qiu Ju, a subordinate of Zhan Jinguo, to supervise Boss Wang's purchase. Han Jinxin was trustworthy, and Yang Peng believed that no one was watching.
Han Jinxin, the former official of the imperial court, did not spend money recklessly. Qiu Ju, who was in charge of military procurement, first went to supervise shipbuilding.
Yang Peng returned to Tianjing New City and found an independent yard in the Qiangnu Workshop as a research place for steam engines. The principle of a steam engine is very simple. It is nothing more than using the expansion pressure of water when it is heated to turn into steam to promote motion, and then
It also uses the vacuum suction movement generated when the steam is cooled into water. The two movements are combined to drive the piston to continuously push up and down, thereby transmitting power to the outside.
In the history of later generations, practical steam engines appeared in the early eighteenth century, which was still beyond the reach of the Song Dynasty at this time. One of the more famous ones is the Newcomen steam engine. The principle of this steam engine is very simple.
After using the power of steam to push the piston, cold water is sprayed into the cylinder to cool the steam, and the generated vacuum can then suck the piston back. By repeating these two movements, it can be driven outward.
Historically, thousands of this simple-structured steam engine were produced and widely used in British coal mines to pump water from the mines. The use of this steam engine helped Britain become the largest coal producer in Europe in the early 18th century.
.Yang Peng has never actually made a steam engine, so he decided to start with the simplest Newcomen steam engine, first easy and then difficult. First make the Newcomen steam engine, and then upgrade it.
But to make a steam engine, the first thing Yang Peng needs to do is a simple lathe. Without a lathe, steel objects cannot be finished. Yang Peng has already made a boring machine before, and the structure of the lathe is similar, except that one is a rotary boring tool and the other is a boring machine.
The object to be processed is rotated, but the same thing is that one thing is rotated to grind another thing, and the structure is similar.
Yang Peng guided the blacksmith and spent five days making a simple lathe, using the crucible steel he smelted as a turning tool. The final lathe could only be said to be a primitive lathe, but it was enough for Li Zhi's use. The lathe was produced
After that, it can be used to turn the piston. Yang Peng wants to make a cylinder with a diameter of 30 centimeters. It is first cast from pig iron and then finished and shaped with a boring machine. In the boring machine, a piston with the same diameter of 30 centimeters needs to be placed.
.Yang Peng asked the blacksmith to use pig iron to cast the shape and then finish it with a lathe.
After repeated comparisons, processing, comparisons, and reprocessing, Yang Peng finally got two cylinders and pistons that fit perfectly. Yang Peng placed the cylinder with the chassis opened on the boiling water and found that the piston was completely airtight.
.Think of it, even if higher pressure water vapor comes in, the air leakage will be very slow. Yang Peng made a push rod on the piston, which is pushed by the piston that moves up and down.
Then there is the cooling device. Yang Peng fixed a cold water bucket next to the piston. The cold water bucket is connected to the bottom of the cylinder. There is a valve at the connection. A mechanism control valve is made at the outermost end of the push rod. If the push rod is pushed up by water vapor,
When it reaches the top, the mechanism is opened, and cold water is sprayed into the cylinder to cool the steam. Once the water vapor cools, the piston drives the push rod to move downward. When it reaches the bottom, it touches the mechanism to close the cold water gate, and so on.
The next step is to make a boiler. This boiler must be large enough to produce enough steam for propulsion. After the boiler is completed and connected to the cylinder, the entire Newcombe steam engine is completed. Yang Peng spent five days making each component and putting the components together.
Twist them together and start testing whether what you did is successful.
As soon as the boiler was heated up, Yang Peng found that the entire steam engine was leaking air everywhere. There was not much air leakage between the finely machined piston and cylinder, but the joints of the pipes were screwed together with threads, and the gaps were large. At this time, everywhere
They all sprayed water vapor outside.
However, even if there is air leakage everywhere, the steam engine is still successful. This is because the intensity of the water vapor burned in the boiler is higher than the intensity of the air leakage in the pipes. The water vapor pushes the piston to do work and constantly moves up and down. Because there is air leakage in each pipe, the cylinder
The air pressure inside is just under control, and the up and down movement of the push rod is relatively stable, seven times.
This Newcamen steam engine has finally been built. However, the efficiency of the Newcamen steam engine is very low, and a lot of firewood can be burned to generate limited thrust. This is because the water vapor in the cylinder is cooled and the cylinder body is also cooled.
After a while, the hot steam came in and heated the cylinder block, wasting a lot of heat over and over again. Such an inefficient steam engine obviously could not meet Li Zhi's needs. Yang Peng wanted to gradually transform this Newcomen steam engine into a watt steam engine.
Steam engine. Watt's biggest improvement to the Newcomen steam engine was the condenser. With the condenser, the cylinder block will not be heated and cooled repeatedly. The condenser is actually a large iron can, connected to the cylinder, with cold water inside. Condenser
The switch is controlled by a mechanism. When the piston is pushed to the top, the switch is opened, and the steam enters the condenser and is cooled into water. When the piston falls to the bottom, the switch is closed, and the steam has nowhere to escape and accumulates in the cylinder, pushing the piston back to the cylinder.
Push up.
But when making the condenser, Yang Peng discovered that this condenser requires a higher air pressure than the water spray cooling method. Such high air pressure cannot be gathered in the pipes with leaks everywhere, so he must find a way to block the leaks. But
There is no high-temperature resistant rubber these days. After much thought, Yang Peng didn't think of anything that could be used to block the leaking pipes. Yang Peng had no choice but to use softer materials available on the market to test them one by one.
But I tried all kinds of textiles, but the effect was not good. The silk that looked smooth and soft became charred and caked when burned by high-temperature steam. The material that is more resistant to high temperatures is linen, but linen has larger pores.
, and cannot block the leaking steam.
After several days of testing, Yang Peng still couldn't find a material that could block the air leakage. Yang Peng was a little stumped. The principle of this Watt steam engine is simple, but the details are still very complicated to make, even if a detail is not done.
Well, it can't drive the entire steam engine.
Speaking of which, copper or lead is relatively soft and can withstand high temperatures of hundreds of degrees. Do we need to use copper and lead to make pipe joints? This is very troublesome to do. A young blacksmith who was transferred by Yang Peng to make a steam engine watched Yang Peng these days.
Peng conjured a Newcomen steam engine and admired Yang Peng very much. At this time, when he saw that Yang Peng was encountering a problem, he interjected and said: "Your Majesty, if you soak linen in oil for a day, the contents of the linen will
The pores will be blocked by grease, which may be useful.”
Yang Peng was stunned, but he didn't expect that there was such a way. He patted the young blacksmith's head and followed the blacksmith's method. Wrap oil-soaked linen cloth around the threaded interface, tighten the interface, and restart the steam engine.
.
At this time, Yang Peng found that there was no air leakage in the pipe. Yang Peng said to the young blacksmith: "The suggestion is good, I will reward you ten taels of silver!" The young blacksmith made ten taels of silver with just one sentence. He was overjoyed and smiled.
It almost reached the back of his head.
Since the last time Huyan Chijin returned home, Yang Dezheng has been pestering Huyan Chijin all day long about how to beat Xiao Tianyou, or he was practicing plum blossom darts, or practicing handguns. Yang Bamei chatted with several aunts.
After the last incident, the commander of the Tongchui Squadron in front of the palace, Tongchui Cheng Pu, canceled the marriage. Now Yang Bamei is already twenty-five years old and has not yet gotten married. In the Song Dynasty, she was an old girl. The family members are also very anxious, Yang
It doesn't matter to Qi.
He couldn't tell Yang Yanzhao what was in his heart, nor would he tell the Eighth Prince. Facing the Eighth Prince's question, Yang Yanzhao replied: "The Eighth Prince, princes and generals, for the boy, it's just a matter of time. Boy.
I feel that today’s Yang family does not need to risk the lives of their relatives for the sake of wealth.”
Yang Yanzhao said sincerely: "In the kid's heart, the lives of relatives are far more important than wealth." The Eighth Prince stared at Yang Yanzhao with a complicated expression. He was also a well-informed person. Like Yang Yanzhao, the lives of relatives are more important than wealth.
He didn't see many important people. After a moment of silence, the Eighth Prince shook his head and sighed, "You kid, you take feelings too seriously."
Yang Yanzhao shrugged and said with a smile: "Maybe..." The Eighth Prince smiled happily, "Your Majesty will not like your character..." Yang Yanzhao said calmly: "It doesn't matter..." The Eighth Prince laughed, "Your Majesty
It doesn’t matter if you don’t like it, I like it. I have been plotting and plotting all my life, but I just don’t like those who plot and plot in front of me.”
"This world is destined to be ruled by scholars and emperors from now on." After saying this, the Eighth Prince laughed and left. Yang Yanzhao smiled lightly. The fact that the Eighth Prince could say this sentence proved one thing.
The Eighth Prince knew the content on the stele erected by Zhao Kuangyin in the Imperial Ancestral Temple. The Eighth Prince was instructing him. He was telling him in a subtle way that literati had a transcendent status in the Song Dynasty.
Yang Yanzhao drank all the tea, paid for the tea, got on the sedan and returned home. When he returned to the east courtyard of Yang Mansion, he took a closer look and found that after Chai Xichun went out, Yang Yanzhao relaxed a lot. He simply ate some food.
Later, he started practicing with the tiger-head black gold gun in the yard.
Yang Yanzhao has been able to complete the twelve-style routine of the Liuhe Army's war gun. Now he only needs to consolidate it. After completing one set of marksmanship, Yang Yanzhao was sweating profusely. When he was about to go back to the room to wash up, he saw Luo Ye hurriedly entered the east
hospital.
"Is something wrong?" Yang Yanzhao asked. Luoye nodded with a cold face, "Everything under the ground in the house has been dug out." Yang Yanzhao was stunned and said cautiously: "Take me to have a look." Yang Yanzhao followed.
Fallen leaves rushed to the foot of the west wing.
Several simple wooden houses were built there. A group of craftsmen were guarding the surroundings of the wooden houses intentionally or unintentionally. These craftsmen were all impersonated by people from the Volcano Camp. The craftsmen saw Yang Yanzhao and Luo Ye, and secretly made way for them.
The two of them went over and entered the wooden house. When they saw the rows of lead pipes inside the wooden house, Yang Yanzhao looked very gloomy.
"There should be more than thirty of them, right?" Luo Ye said coldly: "The total number of lead pipes in the four rooms is more than one hundred and forty." Yang Yanzhao knocked on the lead pipes, making a dull sound. "Dong.
There is no digging under the courtyard yet. In other words, the number of lead pipes underground in the Yang Mansion may exceed two hundred." Yang Yanzhao clenched his fists and a cold light flashed in his eyes.
"It's really vicious." Yang Yanzhao turned to Luo Ye and asked, "What do you think?" Luo Ye glanced at Yang Yanzhao and said calmly: "According to the investigation by my subordinates, these lead pipes were buried after the Yang family moved in.
"." When Yang Yanzhao heard this, he gritted his teeth and said, "What do you mean... There were a large number of traitors in the Yang Mansion at that time. It is possible that these people are still lurking now." Luo Ye nodded.
"Check!" Yang Yanzhao spat out a word with hatred. Luo Ye hesitated for a moment and asked: "What should we do after we find out?" Yang Yanzhao reached out and patted the lead pipe and sneered: "Don't they like to bury lead pipes? Once verified,
He was a spy, put into these lead pipes, and buried alive."
After hearing Yang Yanzhao's order, there was no expression on Luo Ye's face, and he nodded and accepted Yang Yanzhao's order. In the morning, Yang Yanzhao had gotten a bargain from Gao Huaide, and Yang Yanzhao was still in a good mood. However, seeing these lead pipes
, after learning about the hidden spies in the Yang family, his good mood disappeared instantly.
He returned to the east courtyard with a gloomy face. After gulping down a few sips of water, Yang Yanzhao lay on the simple sofa and felt bored. Yang Yanzhao felt depressed for a short time. Chai Xichun went upstairs with the hem of his skirt. He saw Yang Yanzhao lying on the simple sofa.
, she snorted coldly.
"Hmph!" After a long time, seeing that Yang Yanzhao didn't respond, he snorted heavily again. Yang Yanzhao lay on the sofa and muttered, "Stop humming, I'm annoyed." Chai Xichun was stunned for a moment and ordered Chan'er.
Go down first. She walked up to Yang Yanzhao and saw Yang Yanzhao leaving with a gloomy expression. The expression on her face also changed. "What happened?" Yang Yanzhao took Chai Xichun into his arms.
"The pipes under the house have been dug out, and there are more than 140 pipes. This does not include the ones underground in the east courtyard..." Chai Xichun's eyes widened, "Why are there so many?" Yang Yanzhao laughed, and the laughter was very cold,
"After the east courtyard is excavated, there may be more." Chai Xichun bit his lips, "Lang Jun, how about we move and wait until the lead pipes in the east courtyard are dealt with before moving back."
Yang Yanzhao was stunned, "Where to move?" Chai Xichun said softly: "When I got married, my father gave me a house not far from Xiangguo Temple." Yang Yanzhao thought for a moment, nodded in agreement: "
I'll listen to you... However, if I move out for no reason, if my family asks me..." Chai Xichun patted his chest and said, "Leave it to me. When my parents asked me about something, I said it was uncomfortable to live here.
, I want to rebuild the east courtyard. I believe that my parents will not argue with me because of these trivial matters."
Yang Yanzhao grinned. Chai Xichun did what he said and had already rushed to ask Chan'er to pack things. By the time it was dusk, Chai Xichun had already ordered Chan'er to pack the needed items into a truck. He was sent to pack the things not far from Xiangguo Temple.
The servants of Chuzhai have also returned. "Mr. Lang, let's leave now."
Yang Yanzhao looked at the empty bedroom and was dumbfounded. "Chai Xichun, don't be so anxious, right?" Chai Xichun snorted, "How can we not be in a hurry? It is a major matter related to the inheritance of the heirs. We cannot wait for a moment."
What happened after all? Let’s look at the breakdown next time.
