ps: I have something to go out today, so I will update only once, and I will make up for the third update tomorrow...
Bore explosion is a very serious accident. It may be due to unreasonable design, poor quality of the barrel, insufficient smoothness of the barrel, too much ammunition, or a combination of reasons.
Caused, so it needs to be analyzed carefully. Wan Lei will not try the gun again until the cause of the accident is found.
Wan Lei considers himself not an expert in artillery science, so he can only find the cause from the quality of the barrel. As for other reasons, he can only leave it to professional gunners to find. After analyzing the composition of the iron sample taken from the barrel
, he found that the phosphorus and sulfur content was relatively high, which may be why iron cannons are easily cracked.
After finding the reason, Wan Lei frowned even more, because if he wanted to remove the phosphorus and sulfur from the pig iron, he had to build an open-hearth furnace for steelmaking. And now Shuntian Mansion has exhausted its financial resources in order to build a blast furnace ironmaking plant. In a short time,
The country cannot afford to build new steelmaking plants.
Since it is impossible to make steel, the only way to prevent rupture is to thicken the barrel and barrel, and the artillery cannot be miniaturized. Based on this consideration, Wan Lei modified a mold and cast a thicker artillery.
A hoop is added to the gun body to prevent the barrel from exploding.
This kind of heavy artillery is only suitable for defending cities and attacking fortresses, not for field battles. After all, it is difficult to carry this ton-heavy thing. As for field battles, for the time being, it depends on the cavalry. When there is enough spare power in the future, we can build
When you leave the steel mill and smelt high-quality steel, you can make small cannons and small guns.
At night, with the evening breeze blowing, Wan Lei was playing with a strange machine in the yard. Since the patent for the wax-making process was transferred, the Wan family has lost another job and income, and Chixinchicheng is not idle either.
, busy beside a large wooden box, carefully adjusting the gears and pendulum needles in the box to make a relatively accurate large pendulum clock.
As the capital of the Yuan Dynasty, Beiping City has a tall bell tower in the center, and the drum tower serves as the time reporting mechanism for the whole city. This is different from the previous dynasties that used the inner gate, market tower, Qiao tower or city tower to beat drums to tell the time. Wan Lei had already planned to set up the time.
After the bell design was completed, the Drum Tower was transformed into a large bell tower. It not only told the time for the people in the city, but also served as a symbol of civilization and enhanced the sense of honor of the people of Shuntian Prefecture. This was more popular than overhauling the imperial palace.
As for the human palace city where Emperor Yuan once lived, it has not been renovated for more than thirty years and has become dilapidated. Wan Lei has no intention of repairing it. In the future, he will at most flatten it and turn it into a building for the Senate, Executive Yuan and other institutions.
Headquarters, the rest of the area is used as a park or playground as an entertainment and leisure place for the people.
However, the city wall of Beiping City is in urgent need of reconstruction. The Beiping city defense system includes city walls, city gates, and moats. The city wall is made of rammed earth, with a circumference of about 30 kilometers, a height of about 10 to 12 meters, a base width of 20 to 24 meters, and a top
It is 10 to 15 meters wide and looks majestic, but it is actually a serious shoddy project. That is to say, because the city wall was too shoddy, the Peking Army repeatedly suffered losses in battles.
In addition, because most of the city walls are made of rammed earth, they are easily washed away by rainwater and cause collapse. Take the heavy rain the day before yesterday, for example, many city walls collapsed. Fortunately, the troops sent out for rotation training brought back thousands of prisoners, and added
The last batch captured a few days ago, more than two thousand prisoners, were used to renovate and strengthen the city wall.
In order to make the city wall stronger, Wan Lei and Tie Xuan discussed and decided to temporarily cover the earth wall with bricks and stones. Later, when they have enough energy, they can expand outward and build a city wall with a full masonry structure, or even build a reinforced concrete structure outside the city.
The bunkers and barbed wire fences were used to block and delay the cavalry charge to build an impregnable Peiping City.
"Leizhi, the Normal School officially opens tomorrow night. Do you have time to go and take a look?" Wei'er came over with a plate of preserved fruit and placed it in front of Wan Lei. The reason why the Normal School was able to complete the preparations so quickly is not
Just because Wei'er was a diligent person and because many people gave their full support, not only the clan leaders contributed, but Tie Xuan also sent people to clear out the original Imperial College of the Yuan Dynasty and use it as the school building of the Normal School.
"Go, of course you go. How can I not support my husband in my wife's place?" Wan Lei grabbed a candied date without wiping his hands, but Wei'er slapped it away.
"Your hands are so dirty, don't move, I'll give them to you." Wei'er scolded, picked up the candied dates and brought them to her husband's mouth. Wan Lei waited for a while to open his mouth. This scene made the people next to him
When Zhao Xueer saw it, she couldn't help but roll her eyes and said: "Sister Wei'er, this guy is a big bad guy, don't always spoil him."
"Hehe, don't you envy the love between our boss and sister-in-law? Why don't you quickly find a good family to marry? Didn't your father say that there are several good families who want to marry you? As long as you nod your head, you can become a young mistress.
With clothes on my hands and food on my hands, I am so blessed." Zhao Quanzhong, who was grinding spices at the side, laughed.
"How can a sparrow know the ambition of a swan? I want to be like Mu Guiying, go into battle and kill the enemy and perform meritorious service, so I won't marry and become a young mistress." Zhao Xueer rolled her eyes at her cousin.
"Haha, Sister Xue'er, if you really want to be like Mu Guiying, you must first snatch Yang Zongbao back." Zhao Quanren also smiled.
"Go to hell." Zhao Xueer glared at Zhao Quanren, her face turned red with anger, which made the others laugh wildly.
There were bursts of laughter and laughter in the courtyard. At this time, there was a gentle knock on the door. Zhao Quanzhong went to answer the door. As soon as the door opened, he saw an arrow flying over his head and hitting the trunk of the jujube tree in the courtyard.
When the gang saw it, they immediately stood up and surrounded Wan Lei and Wei'er. They looked around cautiously, while Zhao Quanren and Zhao Renyi hid in the dark.
After a while, no one was seen. Wan Lei frowned and saw that the arrow was wrapped with a piece of paper. He asked Chi Xin to take it off and opened it. There were only a dozen words: We have something to discuss.
Before midnight, we met at the Drum Tower and came alone.
"Who is he? He actually uses this method to deliver a letter. Isn't this a sign of challenge?" Zhao Xueer said.
"No matter who he is, go and call the officials immediately, round up the whole city, and never let him escape." Zhao Quanzhong was so frightened that he broke into a cold sweat and said angrily.
Wan Lei didn't say anything. He just looked at the letter of challenge and could vaguely smell the fragrance of peach blossoms. This fragrance seemed familiar, and he remembered it as soon as he thought about it. It was the one he smelled in Siyiyuan that day.
A scent. Thinking of this, Wan Lei thought to himself: "Mrs. Liu is so courageous. She actually made a 'declaration of war' so blatantly."
"Oh, no, this is not a letter of challenge, but an invitation. However, why did she issue an invitation, and what secret matter did she have to discuss in the middle of the night?" Wan Lei frowned even more when he thought of this.
If it had been in the past, Wan Lei would have given an order and sent people to surround Siyi Yuan, then Mrs. Liu would have been able to escape, but the monk would not have been able to escape from the temple. However, now Mrs. Liu's identity is too mysterious, and her enemies and friends are unknown. If
If you act rashly, you may make more enemies. If you are really invited to go, I'm afraid it will be a trap and you will never come back.
"Boss, what should I do? Go call someone right away." Seeing Wan Lei's silence, Zhao Quanzhong reminded him again.
Wan Lei touched his chin and said, "No need, let's go meet her."
"What? Are you really going? You, you don't want your life!" Zhao Xueer was the first to object.
"If you want to kill me, you don't have to ask me out to kill me. Wouldn't it be better to do it in the dark?" Wan Lei smiled lightly and said, "Since she dares to show her cards to me, why should I be afraid of her?"
