Since Zhu Ling saw that the lid of the kettle was flushed by water vapor, Zhu Youxiao drew a figure for him, Zhu Ling wanted to turn it into a practical machine, he handed over the drawings drawn by Zhu Youxiao to Song Yingxing, and asked Song Yingxing to make a big iron kettle for him with iron sheets, the difference is that the upper mouth of the iron kettle is only one inch in diameter, and he also made an iron pipe two feet long, and fixed the iron pipe on the mouth of the big iron kettle. He made himself a wooden box, like a bellows, but a little smaller than a bellows, with an iron pipe at one end, and a bellows on the other, and then on the bellows handle to the crank of a spinning wheel. In order to move the bellows up and down, he made a small axle. Next, Zhu Ling lit a fire under the big teapot to boil water, and after a while, the water was boiled, and the water vapor was introduced into the wooden box through the pipe, and then when the steam slowly became more pressurized, he pushed the piston in the wooden box forward, and then the spinning cart was pushed up. Succeeded, Zhu Ling jumped up excitedly, and ran away without saying a word, what are you doing? Go and give Zhu Youxiao good news.

Zhu Ling ran to the palace in a fit of anger, because he was doing the test in the original prince's mansion, so when he ran to the Qianqing Palace, he was already so tired that he couldn't breathe, and he didn't have time to let the eunuch report and broke in, but he was hugged by Luo Sigong who rushed over.

Luo Sigong asked, "Lao Zhu, do you want to die?" It's a shame that I know that the emperor is waiting to see you, if I hadn't just arrived, you would have to be beaten to death by the guards, you are crazy, why are you running so fast? ”

Zhu Ling will say something else: "Success, success......"

Luo Sigong is in charge of Jinyiwei, he knows a lot of confidential things, and immediately brought Zhu Ling to Zhu Youxiao.

Zhu Ling finally took a breath now, this guy also forgot to be polite, and directly asked Zhu Youxiao for water to drink, Zhu Youxiao asked the eunuch to give a bowl of water, and Zhu Ling drank it in one go, and then he roughly said the success of the steam engine model.

Zhu Youxiao slapped Luo Sigong on the head and shouted: "Hurry up, let me take a look, quick, quick, quick...... Alas, Luo Sigong, what are you kneeling down, hurry, hurry up! ”

Luo Sigong was slapped on the head inexplicably, he thought he had made a mistake, and then he saw that the emperor was happy, not angry, he was also happy: "Your Majesty, why are you happy to hit me in the head, almost scared me to death, what do you want your ministers to do quickly?" ”

"I'm sorry, I'm sorry, I'm so happy, I'm afraid that the punch will beat Zhu Ling, and it will hit you on the head, I'm sorry, I'm sorry. You go and find Lord Xu Guangqi, Lord Song Yingxing, and Lord Bi Maokang, no, no, they all gather at the Prince's Mansion, and just say what I said, if you go slowly, you will be fined half a year. "Zhu Youxiao is so happy that he can't say anything, this industrialization of the Ming Dynasty is about to begin, a hundred years earlier than Britain, and this will move the steam engine to the warship in the future, and it will not sweep everything.

In less than half an hour, Xu Guangqi, Song Yingxing, Bi Maokang, Sun Yuanhua, Cheng Tianying, etc. all arrived, and no one knew why this little emperor wanted everyone to come in such a hurry, and said that he would be fined half a year for slowness.

When they saw Zhu Youxiao and Zhu Ling standing in front of the big teapot, Zhu Ling kept adding firewood under the teapot. Look at the back of the big teapot followed by a bellows-like thing, behind it is a spinning car, the spinning car is whirring in circles, these people were surprised, this steam engine really made Zhu Ling this guy built, no wonder the emperor is so excited, but what is the use of this thing?

Because of the restrictions of the times, at present, these big bulls only know that Zhu Youxiao likes these strange things, and they don't quite understand the wide range of uses of this steam engine, but everyone is happy when they see that the emperor likes it, Xu Guangqi thinks that the emperor is so happy, this thing must have a use, but he doesn't know if this thing can be used in the army; Song Yingxing thought about how to use this thing to get the most out of it, and the emperor wouldn't let so many people rush here for no reason.

Zhu Youxiao didn't want to show that he was too godly, so he asked everyone happily: "Ladies and gentlemen, do you think that if this spinning car is replaced with a stone mill, how about we use it to grind noodles?" ”

Song Yingxing's eyes lit up: "Yes, Your Majesty, if this is used to grind noodles, it must be much faster than a person, but can it have so much power?" ”

Xu Guangqi said: "Try installing it on the carriage and see if it can pull the cart?" ”

"Well, if you use it on a loom, it might be much faster than a human weaver." Song Yingxing said again.

Bi Maokang said: "If you use it to drive the circular saw and the grinding machine made by the emperor, it will definitely save a lot of effort." ”

Xu Guangqi said: "If you use it to turn the waterwheel, how much land can be watered in that day." ”

A big cow is a big cow, Zhu Youxiao asked like this, and these big cows immediately thought of so many uses. Okay, Zhu Youxiao just watched everyone have fun and let them continue to think about what else this thing could be used for.

Just when everyone was discussing what the steam engine could do, the tragedy happened, and I heard a loud "bang", and the wooden box, which was a pressure-bearing part, couldn't help but explode under pressure, and the water vapor "poof" sprayed out along the pipe, so panicked that everyone scattered and dodged. This was the world's first boiler explosion, but its driving force was a big teapot, which just startled Song Yingxing, who was close.

Zhu Ling was adding firewood under the stove, and this fried wood box frightened him into rolling twice, and he knelt down and pleaded guilty.

Zhu Youxiao said happily: "It's okay, it's okay." Everybody has seen it, let's call this thing a steam engine, okay? The explosion just now, illustrates two problems, one is that the power of this steam engine is very large, if it is built better, it is no problem to let it pull more than a dozen cars, and the other is the safety problem, this is just the energy of a teapot, if it is a cauldron, so when studying its use in the future, it must be tested from small to large, your life is more important to the Ming Dynasty than me, I hope you will study its use more in the future, so that the steam engine will become a wonderful flower of our Ming Dynasty, bloom more flowers, and bear more fruits. Also, we need to improve the tools, for example, how to make the steam engine stop at any time during use, for example, how to make two teapots act as the prime mover at the same time, or more, wouldn't that be more powerful? There are still many problems that need to be explored and improved, all in all, how to use this steam engine and make it play a greater role, please leave it to you.

"Zhu Ling, I will make you the Marquis of Invention and reward you with 10,000 taels of silver. I hope that you will unite all the adults present to make the steam engine stronger and more powerful, and that it can be used in carriages, looms, warships, flour mills, waterwheels, etc., and I will reward you with great rewards, and if these are realized, I will crown you king of invention. Zhu Youxiao was so happy that he almost told the king of invention.

"Thank you, Your Majesty, the minister will do it, and never disappoint Your Majesty's grace." Zhu Ling kowtowed in thanks.

However, since then, Zhu Ling has really become the king of invention, and the machine he made has benefited millions of people in the Ming Dynasty, and the original steam engine has also been named "Zhu Ling Yishi".
