"It's okay, it's okay." Wang Zhixue ran over after Yueji, and when he saw He Zhiyuan, he said, "Master, you're right, the water vapor is really strong." I pressed the lid and stuffed the spout with a cloth, but the cloth on the spout collapsed and hit me in the face. Luckily, I was far away and didn't burn badly. ”

He Zhiyuan looked at Wang Zhixue's face and said with reproach: "Fortunately, you didn't stuff it tightly, otherwise the pot would have exploded." If the pot is fried, you can peel off the skin of your face. ”

He Zhiyuan hurriedly asked Wang Zhixue to wash his face with cold water to relieve the burning pain of the scald. Then let him go to the study to sort out the manuscripts, but not to do that dangerous experiment again.

Back in the house, as soon as He Zhiyuan sat down again, Liang Wensheng asked: "I heard him call you master just now, is this your apprentice?" ”

"It's not like, there is no formal apprenticeship, he keeps calling it that, and I don't bother to correct it. He's obsessed with the science I've just mentioned. He always wanted to learn from me as a teacher and let me teach him science. ”

"On the road just now, the old farmer told me that you funded the construction of a large school hall and planned to let the children go to school for free, but is there such a thing?"

"This is something that my father and Uncle Zhou agreed to, and I just proposed." He Zhiyuan replied.

"Is the science you are talking about also being taught in the Academy?"

"Now I only teach mathematics, and I can't learn anything else." He Zhiyuan replied truthfully: "Now only mathematics has been published in books, and the others are only manuscripts. ”

Saying that, He Zhiyuan took a math book from his sleeve, presented it to Liang Wensheng with both hands, and said: "This is the math textbook I compiled in the school, please Lord Liang to correct it." ”

"Well, I'll see if this science is as practical as you say." Liang Wensheng took the book, handed it over to Liang Wenhui, and then said: "I've been disturbed for a long time, so I'll leave first." I'll talk to you more carefully when I take office. ”

He Shaoyun's father and son wanted to keep him at home for dinner before leaving, but Liang Wensheng politely declined: "Today I am here in Weifu, it is inconvenient, and I will come to the house next time to disturb me." ”

After speaking, Liang Wensheng took the long entourage to leave.

After sending Lord Liang away, He Zhiyuan returned to the study. At this time, Wang Zhixue was sitting at the table in a daze, and when he saw He Zhiyuan coming, he stood up and said, "Master, inspired by the steam in this pot, I have thought of a new weapon, can you help me think about whether it is feasible?" ”

"What new weapon?"

"Master, you see that only a little water in this pot can break the cloth stopper out of the spout, and the collapse is more than a zhang away, and the force is still very strong. If you use iron to cast a thick cauldron, next to the pot is connected to a cannon barrel, add iron sand, iron nails, etc. to the barrel, add water to the pot, cover the pot tightly, ignite the fire and boil the water, and wait for the water to vaporize, and then open the valve of the cannon barrel, the steam is sprayed out of the barrel, and the iron nails, iron sand and other things in the barrel are sprayed out, and the power of killing the enemy is absolutely huge. ”

This Wang Zhixue's brain circuit is different from others, he just finished testing steam, he wanted to give him some inspiration, let him go along the idea of the steam engine. But he thought of weapons, and this one was really different. However, he said that this kind of weapon is not impossible, although it deviates from the development direction of weapons in later generations, but it can also be tried, at least now the bandits can be suppressed.

Besides, his innovative ideas and ideas deserve encouragement, not to discourage his enthusiasm, but to guide him. This person may become China's Edison or Watt in the future, and he will definitely make a big difference in the future, and I think it is definitely cost-effective to accept this apprentice.

Thinking of this, He Zhiyuan said: "Not bad, very good idea. I can draw inferences from the steam in the pot, think of the invention of weapons, the idea is very good, it seems that this time it was not scalded once. I'll take you as an apprentice. ”

"Really? That's great, tomorrow I'll come to the Guru with the six salutations. ”

"Not tomorrow, I have other things to do tomorrow." He Zhiyuan said: "Wang Zhixue, you worship me as a teacher, and you learn science, not Confucianism." Therefore, the Confucian worship of three bows and nine bows is not needed in my place. Wait for a day to find a simple etiquette, even if you are apprenticed, you don't need any restraint and six etiquette. Our science is practical and does not pay attention to form, but to practical results. As long as you have a teacher in your heart, why bother with formality. ”

As a modern person in his previous life, he is really not used to kneeling at every turn, and he doesn't like to be kneeled by others. Fortunately, the Ming Dynasty did not kneel much, and he is now a student, so he can see officials without kneeling. If you travel to the Qing Dynasty, you will kneel down to those Manchu Tartars at every turn, and you will call yourself a slave. He had to go back to the future man and fight hard.

At this time, Wang Zhixue said embarrassedly: "That, that, master, I...... I wanted to experiment with that big * cannon, but ...... I have no money. Master, can you borrow ...... Lend me some silver? ”

Yueji, who was standing on the side, heard Wang Zhixue say this, and was instantly petrified by shock. And such a thing? How can it be done? This master hasn't worshiped yet, people don't want to bind the six rites, and you still borrow money from the master? How does your head look? How do you behave differently than ordinary people? What a weirdo!

Yueji couldn't hold it back, so she said, "Wang Zhixue, is there such a thing as you?" Apprentice to my young master, don't give the silver, and borrow the silver from my young master first, what do you think? Can the entire Ming Dynasty find a second one? ”

Wang Zhixue was counted down, and his face was red with shame. With his head down, he longed to find a crack in the ground to get into.

Yueji continued to count, but was stopped by He Zhiyuan, and then said to Wang Zhixue: "You don't need to borrow my silver from me, as long as you want to research and prototype this cannon, I can give you silver for you to study, this is called scientific research funds, and you don't need to pay it back." If you can really succeed in trial production, you can also get a reward from the master. Say, how much silver do you need? ”

"Ten taels, eight taels will do." Wang Zhixue whispered.

"Where ten taels is enough, I'll give you two hundred taels first, but this silver is for research, not for anything else." He Zhiyuan said.

"Definitely, I promise to use it all for researching this weapon." Wang Zhixiao was so happy that he closed his mouth, and hurriedly swore an oath.

"You make a sketch and show it to me, and then you can get a blacksmith to help you make it. Do you know where there is a blacksmith? ”

"I know, there is a very famous blacksmith in our village, who can build all kinds of weapons, just look for him."

When He Zhiyuan heard him say this, he thought that the craftsman was a baby bump, if he really had skills, he could recruit his subordinates, and it would be of great use in the future.

Thinking of this, he said to Wang Zhixue: "Another day, you invite that blacksmith to my house, if it is really exquisite." You might as well ask him to settle down here, it will be of great use in the future. ”

"Alright, master. Then I'll make a sketch first. As he spoke, Wang Zhixue sat down in front of the bookcase, spread out a piece of paper, and drew it with a brush.

He Zhiyuan glanced at Wang Zhixue, and said in his heart, you are really anxious, you will paint when you say it.

After a while, Wang Zhixue finished painting and brought it to He Zhiyuan to see. Seeing that the paper was thick, round, crooked, and black, He Zhiyuan couldn't help frowning, and said in his heart that it seemed that he lacked a lot of skill in drawing.

At this time, Yueji looked at it on the side, although she couldn't read, she could still read the pictures, pouted and said: "Hey, what are you drawing, the lines are thick, round and flat, and a large piece of black and mushy, I can't see anything clearly, and it is far worse than Miss Zhou's drawing." ”

Wang Zhixue was embarrassed, but argued: "I didn't learn to draw when I was studying in the school, and I know these things there." ”

He Zhiyuan said: "Your drawing skills are really lacking, this drawing is a science, to engage in design research, drawing is the basic skill, I will teach you a method of drawing in the future." I don't have time to study this today, so let's talk about your sketch first. ”

"Master, the weapon I designed is like a big kettle, but the spout is changed to a cannon barrel, and a valve is designed under the cannon barrel, and a bag of iron nails, iron sand and other materials is filled in the cannon barrel......"

After listening to him, He Zhiyuan understood his train of thought, although it was only a preliminary idea, but it also had the lethality of a weapon. As long as it is well sealed, this cauldron can withstand the pressure and does not explode, and the cannon can hit far, but the accuracy cannot be said, it can only be counted where it is hit.

He Zhiyuan then said: "Your idea is right, the key to this weapon is sealing, as long as it is sealed, this pot is strong enough, it will have an effect." Have you figured out how to seal it? ”

"I haven't thought about this yet, please ask the master for advice." Wang Zhixue replied honestly.

He Zhiyuan thought about it and said: "This pot mouth must be designed to be smaller, and it can be designed as a round mouth that protrudes outward, with a thicker round mouth on the top and thinner on the bottom." Tighten with cork and then design an iron clasp to tighten the compact, which guarantees maximum tightness. ”

"As for the problem of valve sealing, I haven't thought about it yet, but we must do the following three things, the first is that the valve should be opened and closed quickly; Second, the sealing should be good, and try not to leak air; Third, the valve should be safe and strong, and should not explode, leak or hurt people. Discuss this with the craftsman, and maybe they'll be able to figure it out. ”

"In addition, the size of this weapon must not be very small, it must be very bulky to cast in iron, and it is very inconvenient to carry it on the march and in battle, so it is better to design a base, and install wheels under the bottom seat, and it will be much more convenient to use horses to pull them."

"Yes, thank you for the inspiration, I think I will be able to find a way to solve the problem of the valve. Master, give this weapon a name. ”

At this time, Yueji preemptively said: "You are so stupid, this weapon was researched by the young master out of silver, and it was inspired by the knowledge in the book written by the young master, of course, you have to use the name of the young master, I think it is called Zhiyuan * cannon." ”

He Zhiyuan almost laughed out loud, Yueji, Yueji, you are really bare*fart* sitting on the saw blade - you really dare to pull, you can also say this? I'm still underage, how do you know my cannon is big? Have you seen it?
