"What's wrong with your face? There's a plaster on it." Li Jun looked at Huang Yongshan and asked. Huang Yongshan's face was a little difficult to see. The right face was red and obviously burned. He put a plaster on his dog skin, and the more indecent it would be.

Huang Yongshan had not spoken yet, and Gundam was so quick-talking that he was arranged, saying, "It must be because you were young and didn't do good things. You secretly went to see the young married woman next door take a bath and gave her bath water."

Gundam's jokes attracted a lot of laughter. Wen Tianxiang, Zhao Qian, Liao Shenggong and others all looked at each other and smiled. Li Jun pointed at Gundam and said, "You, you, you, you, the old naughty boy, are in your seventies and eighties, but you still say these things."

"The emperor is right. General Gao, you are too inappropriate." Huang Yongshan blushed and agreed.

Gundam stroked his white beard with a smile and said, "Boy, you'll blush when you make a joke with you? Tell me quickly, why does your face look like a monkey's butt?"

"General Gao, you're going to arrange someone again, what kind of monkey butt is not monkey butt?" Huang Yongshan felt uncomfortable and glanced at Gundam and said, "Go back to the emperor, my face is hot." I was afraid that Gundam would take advantage of the situation and immediately explained, "It's hot for steam."

There were no steam hair-generating equipment such as boilers in the Song Dynasty, and steam was only produced by boiling water in daily life. Li Jun smiled and said, "Let me guess, did you accidentally burn it if you steal your mouth and cook delicious food?"

"The emperor is wise!" Huang Yongshan admitted frankly, "I was boiling eggs in a clay pot. I forgot to draw pictures and pressed the lid with something. After a long time, the lid was opened and burned my face." In order to produce equipment, he insisted on not getting off the fire and insisted on being in the military surveillance all day long. When he was hungry, he would cook something randomly. Boiling eggs was the most common thing.

"Your kid's mouth is so greedy. It's so hot." Gundam shouted loudly.

Li Jun understood that he was working hard and said, "In the future, you won't have to cook eggs by yourself. I'll send you an imperial chef to cook for you specifically."

The imperial chef serves the emperor. Even if Huang Yongshan has the courage to ask for it, he hurriedly refused: "I have no merits and I will never dare to accept it. Please take it back."

"You don't have to be humble, this matter is settled." Li Jun said without any intention of letting go, "You can save some time and make more equipment. You have made a lot of contributions to this battle."

This time, Gundam did not make things difficult for Huang Yongshan and agreed very much: "Yes, yes, yes, the emperor is right. Your kid's contribution is so great."

Only by making steel crossbows and hand crossbows and precious swords can Lin'an be safe. Huang Yongshan's contribution is indeed great, and Wen Tianxiang and others nodded in agreement.

It is rare to cherish his subordinates in all dynasties. Huang Yongshan was very moved and said with tears in his eyes: "Thank you, the emperor. The emperor doesn't know that this burn is not scattered. This reminds me of one thing. I think steam can break the lid and can also impulse other things. If it is used well, it is a good motivation. What we lack most at present is manpower. Insufficient manpower limits the production of equipment. I think if steam is used as power, it can save a lot of manpower, and our equipment production will be much faster. I want to think that the emperor will not blame him."

Steam is used as power, and for modern people, it is easy to understand. For the Song people, it is indeed a bit of a fantasy and it is hard to believe. Wen Tianxiang opened his eyes wide and said, "Is this possible? If the power problem is really solved, it will be a great thing with immeasurable merit."

"I don't understand these things that are not powered. I just need you kid to make more equipment for me." Gundam didn't have much talent for technology and said a little, "Boy, you said, if it comes true, how long will it take to produce the equipment I need?"

"This matter is not easy to say, it depends on the specific situation. If conditions permit, it will naturally be fast. If conditions are not met, it will not be fast." Li Jun did not want to make Huang Yongshan, a scientist, too embarrassed, to relieve his embarrassment, and then asked: "Steam can be used as power. How have you been studying it?"

The famous industrial revolution was completed under the promotion of steam. If there was no steam engine of Watt, it would be difficult to say whether the industrial revolution could still be carried out. If this idea became a reality, many problems could be solved, and Li Jun's interest suddenly became aroused.

Li Jun said this, Huang Yongshan was very energetic and said, "Back to the emperor, I have considered these days and drew a sketch. This matter is too complicated, and there are still many questions that have not been figured out."

"I remember Watt's steam engine drawings, I'm afraid you can't make them." Li Jun thought to Huang Yongshan, saying, "Can you show me the drawings?"

Although the technological level of the Song Dynasty was very high, even Li Jun was a little afraid to think about building a steam engine. Not to mention anything else, it was based on the machinery industry. The machinery industry in the Southern Song Dynasty was difficult to meet the requirements, and there was not even a machine tool, so why not talk about steam engines?

If you can get Li Jun's guidance, you may make great progress. Huang Yongshan was very happy and took out the drawings and spread them on the table, saying, "Prince, please see."

Wen Tianxiang and the others didn't understand the technical problems very much. They couldn't help frowning when they looked at the lines, so they were a little confused.

When Li Jun saw it, he almost fell to the ground and felt dizzy. If it were made according to Huang Yongshan's drawings, it would definitely be the famous Newcomer steam engine. There are differences between the two, and from Li Jun's perspective, it would not be much different.

People may not know about the Nükmen steam engine, but people know about the Watt steam engine. It can be said that the Watt steam engine is an improved version of the Nükmen steam engine. The reason why Watt was able to invent his steam engine is that he has long studied the Nükmen steam engine, absorbed the strengths, and added four main devices to improve it. Therefore, it can be said that without the Nükmen steam engine, it is impossible to have a Watt steam engine.

When Li Jun saw this drawing that was very similar to the Nükmen steam engine, he was so surprised that his chin almost fell off. The manufacturing of steam engines must be based on a developed manufacturing industry, especially the machinery manufacturing industry, to be of considerable level to be built. Otherwise, Li Jun clearly remembered the drawings of Watt steam engines, and had already drawn them for Huang Yongshan and others to produce them.
