After Zhu Cijiong came out of the imperial study, he was not in a hurry to send someone to pass on Xu Guangqi, he still had many questions to consider.

First of all, the rewards given by the glory mission are too many, and he still hasn't figured out how much machine tool knowledge he has in his head.

Then, the specific personnel involved in the construction of the military industrial system also need to have a rough allocation plan, and the five of them cannot make weapons by relying on Xu Guangqi alone.

Finally, the most important point is that he is the emperor, and it is impossible to go to the scene every day to guide Xu Guangqi and them to make machine tools and weapons. Therefore, he must let Xu Guangqi fully understand the principles, functions and functions of various machine tools, otherwise they will not be able to make machine tools, and even if they do, they will not be used.

Because he was too involved in thinking about the problem, Zhu Cijiong didn't pay attention to where he was going, and before he knew it, he came to the side hall where Ming Xizong used to do carpenter work.

In the past, when he came to the Qianqing Palace, he basically went directly to the side hall to 'supervise' his father, and this road can be said to be the most familiar to him. Now that Ming Xizong is gone, he still subconsciously walked here.

Zhu Cijiong walked into the side hall, looked at the familiar wooden utensils, and couldn't help but think of the time he spent with Ming Xizong, a wave of family affection poured into his heart, and his eyes couldn't help but be full of tears.

This Ming Xizong is actually a very good father, he takes care of himself in every way, cares for him, and it is false to say that he is not moved. However, he was not a qualified emperor, and in order to evade responsibility, he reused Wei Zhongxian and other eunuchs, so that the official system was corrupted, and the government was in trouble.

Now that he is gone, leaving behind a stormy Ming dynasty, Zhu Cijiong really doesn't know whether to be grateful to him or to resent him.

He walked to the place where Ming Xizong often rested, sat on the small board he often sat on, and slowly began to think.

This thought was more than an hour, Cao Huachun stood aside, looking at the little emperor distressedly, he thought that Zhu Cijiong was missing the first emperor, standing there and not daring to take a breath, for fear of interrupting the little emperor's worries.

Of course, Zhu Cijiong is not nostalgic for Ming Xizong, he is thinking about how to teach Xu Guangqi the knowledge of machine tools.

He pondered for more than an hour, and finally figured out that the solution he came up with was very simple, that is: guidance.

To let Xu Guangqi understand the principle of the machine tool, it is not enough to just give them drawings, it is best to let them 'invent' by themselves, only in this way can they make qualified machine tools.

Speaking of this invention, most inventions in human history have originated from the bold associations of the inventors.

That is to say, in order to invent and create a new thing, you must first dare to think, think boldly, and think unconventionally.

Then, the direction must be right, association, association, is must be related to the imagination, if you want the bull's head is not the horse's mouth, you can't invent things.

It is not difficult for Zhu Cijiong to let Xu Guangqi and them 'invent' the original machine tool, because all the things to be 'invented' are in his mind, and this direction must not be wrong, and the rest is to guide them to think boldly.

Although there were many prototypes of machine tools in the Ming Dynasty, they could not be called real machine tools. Because they all lack one core thing, and that is a stable power source.

Powered by foot, hand, or by the elasticity of trees or bamboo, it is not a machine tool in the true sense, but a more complex tool.

The power source of the machine tool given by the glory task of the system is the most primitive steam power.

Even if you are a modern person, if you don't look it up on the Internet, you don't know how this steam is converted into power.

The steam engine is very esoteric, complex, and professional when you think about it, and most modern people dare not imagine this thing. Not to mention the Ming Dynasty hundreds of years ago, if you don't be bold, you really don't dare to think about it.

In fact, the principle of the steam engine is very simple, it may be difficult to make those advanced steam engines used in later trains and ships, but it is still very easy to make the most primitive steam engine.

This principle of steam power, everyone, as long as you know the steam thing, can understand what steam power is all about when you think about it.

It's just that most people don't think about it, and few people will think about more advanced motors, who has nothing to think about steam power!

Ancient people were different, at that time it was almost all human or animal power, and many scholars and scientists were pondering a stable power source.

As early as the first century A.D., the Greek mathematician Heroh discovered that steam could provide power, and he was very bold to think about it, but he thought in the wrong direction, and as a result, he invented a useless toy: the steam spinning ball.

In 1679, the French physicist Denis Barben saw the steam emitted from the pressure cooker, and he also began to make bold associations, and he thought in a different direction from Hero, he thought about how to convert this steam power into something that replaced human and animal power, so he built the first steam engine.

After a slight glance at the knowledge related to system rewards, Zhu Cijiong felt that the steam engine was really simple, and he only needed to guide it a little, and he believed that Xu Guangqi would definitely be able to make it.

So, he asked Cao Huachun to send someone to pass Xu Guangqi into the palace for an audience, and at the same time asked people to find a copper kettle and a small stove for boiling water, and then asked Cao Huachun to prepare some small objects, and began to wait for Xu Guangqi while boiling water.

Soon after the water boiled, Xu Guangqi rushed over, rested for almost two hours, his alcohol strength had passed, and he seemed more restrained, not as casual as at noon.

After the monarch and the master and apprentice exchanged great salutes, Zhu Cijiong led Xu Guangqi to the kettle.

Xu Guangqi looked at the copper kettle of boiling water, and looked at Zhu Cijiong inexplicably, is this to invite me to tea? I didn't see the cup!

Of course, Zhu Cijiong didn't want to invite him to tea, he pointed to the steam coming out of the lid and spout and asked, "Master, what do you think when you see this hot steam?" ”

Xu Guangqi is even more strange, thoughts, what ideas, who doesn't boil water, everyone has seen this heat, this thing that can be seen every day, what ideas can there be!

He thought about it for a while, and reluctantly replied: "If you go back to the emperor, Weichen thinks: This heat must be very hot, and you can't touch it with your hands." ”

Well, the direction is not right, Zhu Cijiong continued to guide: "Then have you ever wondered why this pot lid moves?" ”

Xu Guangqi was entangled, what was there to ask about such a simple truth, but the emperor had to answer the question, so he had to answer helplessly: "If this heat bubbles out, it will naturally move with the lid of the pot." ”

There was a little bit of meaning, Zhu Cijiong clapped his hands and said, "That's good, come on, plug the spout." ”

Hearing this, the little eunuch who was waiting on the side hurriedly walked up respectfully, grabbed a cork with a thick cloth, and blocked the spout at once.

At this time, the lid of the kettle trembled even more, and it had the posture of flying up from the copper kettle.

Zhu Cijiong stared at Xu Guangqi again and asked, "Teacher, do you understand?" ”

Understand what? Xu Guangqi was embarrassed, he had to reply truthfully: "This, this, the heat can only come in one direction, and it seems that the momentum is greater." ”

This answer is already very close to the power, and Zhu Cijiong excitedly ordered: "Press the lid of the pot." ”

The little eunuch took out another thin cloth, wrapped the lid of the kettle, and pressed it vigorously on the copper kettle.

He had just pressed the lid when the cork on the spout flew out with a "poof".

Xu Guangqi looked at the spout in surprise, thoughtful.

Zhu Cijiong guided again: "The power of this hot gas is not small, right? What are your thoughts now? ”

Xu Guangqi nodded subconsciously, and then looked at Zhu Cijiong embarrassedly, he really couldn't figure out what Zhu Cijiong meant by showing him this thing.

Zhu Cijiong asked the little eunuch to bring a small cylinder that had been prepared in a hurry and handed it to Xu Guangqi for him to take a closer look.

Xu Guangqi took the cylinder and looked at it, stunned.

It can be seen from the delicate appearance of this small cylinder that this must be the posthumous work of the former emperor, and it is estimated that it was used to hold tea or something.

However, now this delicate wooden cylinder has been changed beyond recognition, and the side carved with the dragon and phoenix pattern has been cut into two small holes above and below, a larger hole has been opened in the lid, and a rough log pole sticks out of the big hole, how strange it looks.

This is the legacy of the emperor, it's too loser, this thing can now be said to be priceless! Now it's all ruined!

Of course, Zhu Cijiong didn't care about this, what he was thinking about was how to guide Xu Guangqi to make the original steam engine as soon as possible.

He didn't seem to see Xu Guangqi's expression, and continued to guide: "Teacher, open it and take a look." ”

Xu Guangqi broke open the lid of the cylinder with a painful face and looked at it carefully.

The contents are very simple, there are no changes in the log cylinder, but there is a log board on the log pole, which is exactly the same as the inner diameter of the log cylinder.

Looking at it, he couldn't help but turn his gaze to the kettle, he looked at the hot air spewing from the spout, and then looked at the two holes in the side of the barrel, and then he closed the barrel again, and directly plugged the hole under the side to the spout of the kettle.

"Whoosh" The log pole on the lid of the log cylinder rushed outward, and all of them protruded.

He plugged the hole above the side to the spout of the kettle, and "whoosh" the log rod on the lid of the cylinder was retracted and retracted.

Xu Guangqi tried it a few times regardless of his hot hands, and then, he looked at Zhu Cijiong with admiration, he could think of it, it was worthy of being a fairy!

Seeing him like this, Zhu Cijiong knew that he had understood the method of converting steam into power, so he hurriedly hit the railway while it was hot: "What if this cylinder is made of copper and made it bigger?" ”

Xu Guangqi replied with fanatical eyes: "It must be greater than the strength of ordinary people!" ”

Zhu Cijiong feels that today is almost the same, Rome was not built in a day, and the steam engine was not made in a day, now the core thing Xu Guangqi already knows, the next step is to wait for him to make the real copper cylinder.

So, he waved his hand and said, "This wooden tube will be rewarded to you, go back and hurry up like this, make a few copper ones, big and small ones, make a few more." ”

He thought that Xu Guangqi should retire happily, but he never thought that Xu Guangqi was dumbfounded.

He said hesitantly: "This and this, Weichen is just a waiter in the Ministry of Rites, and it is okay to ask colleagues in the Ministry of Industry to make a telescope, but if you do this, people may not agree!" ”

Zhu Cijiong slapped his forehead when he heard this, and said embarrassedly: "Well, I was negligent, Wang Zheng is in Shuntian Mansion, right?" I then ordered him to be transferred to the Ministry of Works. ”

If I was afraid that the eunuch party would go against the tune at other times, but today it was just right, I just promised them to appoint and dismiss so many cronies, and appoint a few more by myself, this is the meaning of mutual exchange and peaceful coexistence, and I think the eunuch party will agree, so that the paralysis effect will be better.

Of course, you can't ask for these positions in the name of the emperor, and if you are rejected, there will be no room for maneuver. Let's just say that it is Xu Guangqi's suggestion, who calls him his 'teacher', there is no purer 'new emperor faction' than him, this pot, he has to carry it!
