Chapter 748: My knowledge as a scientist is the truly useful knowledge
While the battle between the Qin army and the five-nation coalition forces was in full swing outside Hangu Pass, Li Yunze was experimenting with planting new crops in a farmland outside Yueyang City.
After these years of on-the-spot investigation in the Qin Dynasty, he had the most intuitive understanding of the agricultural production and needs of the Chinese people in this era.
The most important thing is carbohydrates, commonly known as the staple food. After years of cultivation and cultivation, the corn can already meet the demand with the blessing of water conservancy facilities and three fertilizers.
After all, Da Qin's population could only support millions of people. The combined efforts of water conservancy, fertilizers, new agricultural tools, and cattle from the grassland produced enough corn.
In Li Yunze's view, Da Qin needs supplementary food and meat the most at this time.
Although in this era there are large swamps and forests outside the city, with wild animals everywhere.
But wild animals are not stupid either. They will actively avoid the terrifying Ape erectus, and will fight tooth and nail when they cannot avoid it.
Not only is it difficult to obtain, but the body carries many germs and parasites, which is very harmful.
The most important thing is that the meat is too woody and tastes bad.
Therefore, Li Yunze proposed to beat the nomadic tribes on the grassland, rob their pastures, and rob their cattle, sheep, and horses to provide Daqin with a sufficient supply of meat, thereby improving physical fitness and average life span.
Apart from that, only non-staple food is left.
The so-called non-staple food is a broad term.
Everything from chicken, duck, and fish to fruits, vegetables, milk, eggs, and even seasonings and candies can be called non-staple foods.
Li Yunze is too lazy to go around the world to collect seeds, and he has no time and energy to cultivate them from generation to generation.
It's very natural, he brought the seeds directly from the modern world.
The first thing to appear is naturally chili pepper, which is regarded as the favorite foreign seasoning of the Chinese people.
At this time, Li Yunze was squatting in the farmland full of peppers, wearing a straw hat, and carefully tending the crops in front of him like a farmer.
"Actually, the king had previously intended for you to lead troops to Hangu Pass to fight against the Five Nations Allied Forces."
Li Si, who was beside him, stretched out his hand out of boredom, pinched a chili pepper and played with it in his hand, "What a great opportunity. I don't understand what you are thinking. You actually refused such a good opportunity. Could it be that you don't know how to fight?"
"
Li Yunze, who was busy removing insects, responded without looking back, "I have fought more battles than you have ever heard of. There is no reason, I'm just tired of it."
Li Si naturally sneered at these words, thinking that Li Yunze was really capable of bragging~~~
What he didn't know was that what Li Yunze said was true.
When it comes to fighting, after so many worlds, I have really fought enough.
Moreover, he is not very interested in feuding princes fighting for the world.
As for fighting foreign enemies, whether they are nomadic tribes in the north or barbarians in the south, they are all similar to primitive societies, and most of the weapons used are wooden sticks, which is not interesting at all.
It is enough for Ying Zheng to deal with these little Karami.
Li Si was still complaining endlessly, "Those old Qin people are becoming more and more domineering. Not only do they not let go of military power, they also interfere in political affairs and fight everywhere..."
Li Yunze, who had rid himself of the insects, clapped his hands, picked up the basket from the ground and started picking red peppers.
After Li Si finished complaining, Youyou said, "They like to fight, so let them fight. Anyway, they are fighting with people from the Chu family, so what does it have to do with you?"
"But if the Chu clan loses, then it will be my turn to wait for these outsiders." Li Si said unwillingly, "Don't let those of us who have made great contributions end up like lackeys."
.”
"Heh~~~"
Li Yunze, who had picked half the basket, stood up and walked to another vegetable field on the side, where vitamin-rich carrots were grown.
"Your Majesty is not a fool. How could he allow the old Qin people to take control of the military and the court? If that were the case, wouldn't it mean that Your Majesty would become a puppet, and everything in power would be in the hands of others."
Li Yunze, who was pulling carrots, comforted Li Si, "Just watch the old Qin people fighting with the Chu people. Anyway, even if the Chu people collapse in the end, the king will support new forces."
Having said this, Li Yunze put a carrot into Li Si's hand, "You are getting more and more important from the king now, and I will definitely support you to ascend to the throne."
Hearing this, Li Si looked excited and even became a little nervous.
He actually understood what Li Yunze said, but he just wanted to get recognition and support here.
It was only at this time that he expressed his true thoughts in a slightly coy way, "If I can be reused by the king, I will do my best to assist the king. But..."
How could Li Si's little thoughts be hidden from Li Yunze's discernment?
Li Yunze, who has experienced all the worlds, has competed with countless scheming people.
After pulling out half the basket of carrots, Li Yunze walked towards the house not far away, and then responded, "It's just that you are alone. I'm afraid it will be difficult to fight against the old Qin people, right?"
"exactly."
Li Si hurriedly followed, "Although many people have joined my sect recently, they are nothing outstanding..."
"You are a disciple of the Legalist School, or a disciple of Xunzi." Li Yunze walked forward, waving his hands without looking back, "Don't tell me, you are the only disciple of your teacher, and you are the only successor of the entire Legalist School.
!”
List stopped dead in his tracks, and a figure appeared in his mind, which was his classmate and friend when he was studying.
When passing by the tomato field, Li Yunze reached out and picked two tomatoes. "You came just in time today. I will make you a tomato scrambled egg."
As the technology of ironware has advanced, things like iron pots will naturally appear under Li Yunze's suggestion.
With the iron pot, naturally there is cooking.
Because there was no shortage of livestock in Daqin at this time, there was also a lot of animal oil. When cooking, add enough oil, salt and condiments. The color, flavor and flavor have jumped by more than one level compared to before.
Li Si had a delicious meal and was so satisfied that he wanted to pack up a few cars and take them back to the mansion to enjoy.
"Let's talk about it in a few years."
Li Yunze chuckled and refused, "This is for breeding. When it is fully rolled out in a few years and every household has it, you can eat as much as you want."
When Li Si left, he still took away half a cart of things, mainly seeds. He said he would go home and pull out all the flowers and plants in the garden and plant these good things.
Li Yunze didn't say much about this approach, because he knew very well that Li Si, who was gradually being reused by Ying Zheng, was no longer the same Li Si who was worried about the travel expenses to leave Qin in the recruiting hall.
After all, Li Si himself understood the truth and things, and it was just a test to come to him.
After all, as long as Li Yunze is willing to step forward, the person Ying Zheng will use to balance the court must be Li Yunze, not Li Si.
Li Yunze has seen this kind of scheming so many times in the world of all heavens and realms that he has long been accustomed to it.
Watching Li Si's huge motorcade gradually go away, Li Yunze shook his head, put on his straw hat, and continued to do farm work in the fields.
In the following days, Li Yunze stayed in the countryside with the craftsman and did not go out. Except for the occasional visits from Ying Zheng and Zhao Ji, outsiders did not even know where the Taifu was.
Correspondingly, the craftsmen of the Yan Kingdom stayed at the Taifu's residence and even arranged for people to enter the residence, but they did not get any useful information.
Time flies so fast, and in a blink of an eye it is the eighth year of King Qin's reign.
This year, Zhao Ji officially handed over the Great Seal of Qin to Ying Zheng, and the king finally took full control of all the power of Qin.
It was also in this year that Ying Zheng came to be a craftsman supervisor and saw the original version of the steam engine.
"The principle of a steam engine is actually to boil water."
Li Yunze fulfilled his duties as a Tutor conscientiously and taught Ying Zheng, "After boiling water, high-pressure steam will be produced. Use the expansion force of this high-pressure steam to push the piston movement to obtain energy conversion."
Steam engines are not actually Zentraedi technology. As early as BC, the Greek mathematician Hero invented the most primitive prototype of a steam engine. At that time, it was called a pneumatic ball, and its principle was basically the same as that of a steam engine.
Even the real steam engine was not invented by Watt. Steam engines had already appeared before him and had even been used in practical applications in mines and other places.
What Watt did was just improve it and promote its popularity in industry.
Ying Zheng looked blankly at the big guy in front of him who kept making whining sounds, and his mind was filled with excitement: "Such a magical weapon..."
"I told you so!"
Li Yunze immediately interrupted him, "This is not the work of God, this is the power of science!"
"yes."
Ying Zheng calmed down and immediately bowed to Li Yunze with a serious look on his face. "Thank you, Master, for warning me. It's just Meng Lang. This is what I do as a scientist, and it is the practical application of mathematics, physics and chemistry."
Well, in Ying Zheng's view, all the various schools of thought are useless. They all talk about the nature of the mind with rhetoric. It's like us scientists, who talk about practical applications and can bring actual benefits.
After saying this, Li Yunze nodded with satisfaction, "A boy can be taught."
Li Yunze had taught him this matter a long time ago, and they even made some parts together. Ying Zheng also knew the specific principles and composition.
It was just that it was the first time I saw a steel monster that could move on its own, so I was a little distracted for a moment.
"Master, what can I use this thing for?"
After being shocked, Ying Zheng asked about the specific use.
"It has many uses, but right now, it is mainly used in mining and transportation industries."
Li Yunze began to give Ying Zheng on-site scientific explanations, such as how it can improve production efficiency in mines.
In this era, most of the mining operations involved mining surface minerals, and going deep underground only happened after Daqin developed gunpowder for mining.
Now with the cooperation of steam engines, the efficiency will naturally increase again.
Ying Zheng, who nodded repeatedly, quickly raised his doubts, "It is indeed good to increase production, but if so much is produced, where will it be used?"
"I think that iron ore is indeed good and can be used to smelt and make a large number of iron tools. But if you dig out so much coal, you won't be able to use it all."
There are many coal mines in Guanzhong, and part of the coal produced is used as coking coal for iron smelting, part is used as fertilizer, and part is used for heating.
It's still the same old coal stove, briquettes, honeycomb briquettes and so on. With these cheap coals, the people of Qin State really feel much more comfortable in winter.
Not only the Qin State, this kind of low-tech thing, coupled with its large-scale popularization, naturally the countries in the Kanto region also learned from it and quickly spread it in other countries.
"Coal is very useful. We in China have a large amount of coal reserves. We should have started the industrial revolution... It's all the barbarians' fault..."
Li Yunze shook his head and changed the topic back to "Coal can be used to drive these steam engines, and the calorific value conversion ratio is very high."
Ying Zheng looked at Li Yunze seriously, waiting for his next words.
"The Western Regions have already reached Khotan." Li Yunze changed the subject here and started talking about the Western Regions. "It's thousands of miles from Khotan to Xianyang City, so transportation is very difficult."
"exactly."
Ying Zheng immediately nodded and responded, "It takes dozens of days to ride a horse. If you go on foot, a trip will take at least a year."
"This steam engine can effectively solve this problem."
Li Yunze, with a smile on his face, stretched out his hand to motion to the whining steam engine, "In front of it, even a thousand-mile horse will eclipse!"
