Chapter 224 The Steam Engine

When Yang Guang returned home after drinking, Wang Yi helped his highness into the house. Xiao Menglan stayed up late at night, waiting for Yang Guang to come back. He looked at the drunk Yang Guang and wiped his forehead with a hot towel to warm him up. Tea.

She wiped Yang Guang's body carefully to make the drunken man feel better, fearing that he would be cold or hot.

When she saw the stab wound on his body, she couldn't help but burst into tears. Yang Guang never mentioned that he was in danger, but she never missed the military report from Shuozhou. When she heard that Yang Guang was sneak attacked at night, I almost fainted immediately.

The words were simple. Seeing the scars on his body at this time, the wounds would not lie. Even if Yang Guangxin said many times that he was fine, how could such a knife wound not hurt?

Feeling that Xiao Menglan was crying, Yang Guang reached out and wiped it gently: "Why are you crying?"

"Nothing, I just miss Your Highness."

"Isn't this just coming back?"

"It's good to be back."

"Are you worried that I went to the battlefield? These are just minor injuries. The injuries on the soldiers at the border are all much more serious than mine. They are not serious."

Xiao Menglan wiped away her tears and said: "If I didn't want His Highness to go to the battlefield, but I know His Highness's ambitions, and I'm afraid that if I speak, my wife will mislead Your Highness, I don't dare to say anything about these things, but Your Highness You have to be extremely careful yourself and don’t let others harm you.”

"I know you are worried about me. This time when the border is settled, there will be no major problems for the time being. I should be able to stay in Daxing City."

He took Xiao Menglan into his arms. During this period of time, Yang Guang was already taller than Xiao Menglan. Boys in the growth and development period always grow faster.

"What do you think of the arrangements for bringing back the Turkic princess?"

Xiao Menglan thought for a while and said: "Since she is a princess from another country, she cannot lose the etiquette of a big country, so she must be treated well. Moreover, the girl has a very cheerful temperament, but she gets along well with the eldest sister. As long as she is not evil-minded after passing the If you are a foreigner, your concubines will be less restrained, but after all, you are from another country, so you should be more careful."

"Don't talk about other things tonight, just sit and discuss the mountains and rivers."

……

In the early morning of the next day, Yang Guang was woken up by Xiao Menglan while he was sleepy. The rosy-faced Xiao Menglan looked at her overworked husband, patted him and said, "Your Highness, you have to go to court today."

"I don't want to go today."

"Your Highness, that's not possible. This is your first morning court meeting since you came back. If you don't go, there may be ministers who will be proud of your favor and achievements. My father must also have many instructions for you. explain."

Yang Guang had no choice but to get up, put on his clothes and go to court.

Above the court, the emperor happily continued to praise this border battle. All the officials were respectful. After leaving the court, Yang Guang was called to the harem again. The empress smiled happily when she saw Yang Guang, who had grown a lot taller. Yan.

"In a year or two, I will be taller than my father-in-law. I am afraid that the original clothes in Prince Jin's palace will not be used. Aunt Li went to prepare a copy of all the silks and satins in the palace and sent them to Jin today. Go to the palace and ask Princess Jin to make some more clothes for our Prince Jin."

The Queen waved her hand, and piles of rewards were sent to Prince Jin's Mansion. Even the East Palace had never given such generous rewards.

After receiving a large number of rewards, Yang Guang dragged his tired body back home. The emperor allowed him not to go to court for a month and have a good rest. Of course, the wedding was after the [-]th, so there was actually no time to rest.

I slept all day when I got home and didn't wake up until noon the next day.

Li Yuan had been waiting at home for a long time and played several games of chess with Li Jing, but Li Jing killed all of them.

He stopped when he saw Yang Guang coming out of the room.

"I never expected to sleep for so long."

"Your Highness deserves more rest after working hard."

"If you go to bed any longer, it will really delay things. Does your cousin have something to do when you come today?"

"Your Highness, the steam engine you ordered before setting off for the expedition has been revealed. I came here to ask you to take a look."

"Oh?" Yang Guang felt excited now, but considering that he had been researching steam engines for quite some time, he should have made some breakthroughs.

He didn't think it was possible to build a usable steam engine now, but there had to be some progress.

"Take me to see it."

Li Yuan brought Yang Guang and Li Jing to the current firearms workshop. Because the emperor was promoting firearms, he gave money and land. The entire area in the south of the city was covered by the firearms factory, and more than 3000 workers were working here.

The steam engine was developed in the firearms workshop.

Yang Guang first took a look at the firearms workshop. Because of the presence of cement and considering the needs of the workshop, the houses built here have the appearance of factories in the modern sense. They are no longer ordinary houses, but have increased height and added factory buildings. size, a whole set of assembly lines are placed in the factory to increase efficiency.

Yang Guang feels that Li Yuan's execution ability is really strong. He can basically do everything he says, and it is feasible after actual verification.

Li Yuan felt that Yang Guangshi was very human. He could think up most of the things based on his imagination, and everything could be implemented.

At this time, the two of them walked to the exclusive research and development room of the steam engine. Li Yuan followed Yang Guang's words that research and development was even more important than production, so the research and development of both gunpowder and steam engines was not left behind.

In the empty factory building was a strange-looking iron machine that Yang Guang had never seen before.

Let them develop on their own and it turns out that the technology tree is still a little bit crooked.

Yang Guang asked them to demonstrate. Unexpectedly, this strange shape actually started a simple piston movement after ignition. At least in principle, it was correct, but this style and conversion efficiency were not practical.

"Call the main engineers who made this thing."

Ulala pulled over a dozen people, some of whom were in their fifties or sixties and some in their teens.

"First of all, you have to seal the steam engine. The inside must be a closed space, otherwise the steam will be useless when it escapes. The contact areas must be as smooth as possible."

At this time, a questioning voice sounded: "But Your Highness, what if it is completely sealed and we can't see what's going on inside?"

"What's the use of seeing it? We want him to work now. As long as he can work, it doesn't matter if you can't see it."

"Oh~" The young man wrote down the key points in his own mind.

"The steam is introduced into a closed space, and there is a lid-like device connected to the connecting rod, which can be called a piston, a movable plug."

At this time, the boy spoke again: "Is it possible to set up a small hole, a pressure relief hole? The switch of the pressure relief hole is connected to the connecting rod. When the piston is pushed to the top, the switch opens, the steam is discharged, and the piston falls. , after falling, the steam is turned off and the pressure is continued, so that a piston can move in both directions."

Yang Guang looked at the young man in front of him who was trying to take notes in great surprise.

Now I'm talking about pistons, but you jump directly to reciprocating pistons?
"What's your name?"

"Your Highness, my name is Li Chun."

Yang Guang thought the name was familiar, and suddenly said with a face full of astonishment: "Where are you from?"

Li Yuanlai introduced him: "Your Highness, although this Li Chun is young, he is the champion of the first craftsman competition held by Nanxi girls. At a young age, his craftsmanship and ideas are extraordinary. He is from Lincheng, Xingtai, Hebei People, many of the craftsmen here are also skilled craftsmen who have stood out in this competition.”

If Yang Guang has found a treasure, if nothing else happens, this should be the Li Chun who built the Zhaozhou Bridge.

He pioneered the use of curved arch bridges to build the Zhaozhou Bridge. He used advanced construction concepts in leaps and bounds without any basic knowledge of mechanics. This kind of talent is included in his own workshop team and is like a treasure. .

Moreover, Li Chun is only a teenager now, and it will still be more than ten years before he builds the Zhaozhou Bridge. If it were him, the chance of using the steam engine would be much greater. His brain is very useful.

Yang Guang immediately said: "You draw a drawing and I will take a look."

Li Chun started painting, took out his painting album, and began to think about how to make it more feasible.
