Yang Guang returned home after drinking, Wang Yi helped his Royal Highness into the house, Xiao Menglan didn't sleep late at night, waiting for Yang Guang to come back, watching the drunk Yang Guang wipe his forehead with a hot towel, and warm the sobering tea.

She carefully wiped Yang Guang's body, making him feel better when he was drunk, afraid that he would be cold and hot.

When he saw the knife wound on his body, he couldn't help but burst into tears, Yang Guang never mentioned that he was in danger, but she never fell behind in Shuozhou's military report, and when she heard that Yang Guang was attacked by someone in the starry night, she almost fainted.

The words are simple, seeing the scar on the body at this time, the wound will not deceive people, even if Yang Guangxin has said many times that he is fine, but how can such a knife wound not hurt?

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

"Not much, I just want Your Highness."

"It's not like it's coming back."

"It's good to be back."

"Are you worried that I am on the battlefield, these are just minor injuries, and the soldiers at the border pass are all more seriously injured than me, and they are fine."

Xiao Menglan wiped away her tears and said: "If I didn't want His Highness to go to the battlefield, but I know that His Highness is ambitious, and I am afraid that if I open my mouth, the woman's opinion will mislead Your Highness, so I don't dare to say much about these things, but Your Highness, you have to be very careful, and the villain will be harmed." ”

"I know you're worried about me, this time I came back to the border to calm down, there is no major incident for the time being, and I should be able to stay in Daxing City."

Took Xiao Menglan into his arms, and after this period of time, Yang Guang was already a lot taller than Xiao Menglan, and boys in the growth and development period always grew up fast.

"How do you think you can arrange it for bringing back that Turkic princess?"

Xiao Menglan thought for a while and said: "Since she is a princess of another country, she can't lose the etiquette of a big country, so she naturally has to stay alive, and that girl is very hearty, but she is quite compatible with the eldest sister, and as long as she is not a vicious person, the concubine will be less restrained, but after all, she is a person from another country, so she still has to be careful." ”

"Don't talk about the side tonight, the mountains and rivers will sit and talk."

……

In the early morning of the next day, Yang Guang was woken up by Xiao Menglan in a sleepy mood, and Xiao Menglan, who had a ruddy face, looked at her overworked husband, patted him and said, "Your Highness, you still have to go to court today." ”

"I don't want to go today."

"Your Royal Highness, that's not good, this is the first early dynasty after you come back, if you don't go, maybe there will be ministers who will be proud of your pampering and proud, and your father must have a lot of orders to tell you."

Yang Guang had no choice but to get up and go up in his clothes.

Above the court, the emperor happily continued to praise the battle at the border pass, the hundred officials were obedient, and Yang Guang was called to the harem again, and the queen looked at Yang Guang, who had grown a lot taller, and smiled happily.

"In another year or two, it will be higher than my father's emperor, and I am afraid that the original clothes in the Jin Wangfu will not be used, Mama Li will go and prepare a copy of the silk and satin in the palace, and send it to the Jin Wangfu today, and ask the Jin princess to make a few more clothes for our Jin Wang."

With a wave of the queen's hand, piles of rewards were sent to the Jin Palace, even for the East Palace, which had never been so generous.

After a large number of rewards, Yang Guang dragged his tired body back home, and the emperor allowed him not to go to court for a month and have a good rest, of course, the wedding date was after the fifteenth, in fact, there was no time to rest.

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

Li Yuan has been waiting at home for a long time and played a few games of chess with Li Jing, but the piece of armor killed by Li Jing is not left.

Seeing Yang Guang coming out of the room, he stopped.

"I didn't want to sleep for so long."

"Your Highness should work hard and rest more."

"If you sleep again, it will really delay things, but my cousin has something to do today?"

"Your Highness, the steam engine you ordered before you set out on the expedition already has an eyebrow, so I specially invite you to take a look."

"Oh?"

Yang Guang is very energetic, but thinking about the research of the steam engine for a while, there should be some breakthroughs.

He didn't think he could build a working steam engine now, but he had to make some progress.

"Take me to see it."

Li Yuan took Yang Guang and Li Jing to the current firearms workshop, because the emperor was very interested in firearms, so he gave money to the land, and the entire square area in the south of the city was the scope of the firearms factory, where more than 3,000 workers were working.

The steam engine was developed in the firearms workshop.

Yang Guang first looked at the firearms workshop, because of the existence of cement, and considering the needs of the workshop, the houses built here have some modern factory looks, no longer ordinary housing forms, but increase the height, increase the size of the plant, a complete set of assembly lines are put into the factory, increase efficiency.

Yang Guang felt that Li Yuan's execution was really very strong, and he basically did everything he said, and it was feasible after actual verification.

Li Yuan felt that Yang Guangshi was very human, and he could think of anything out of thin air, and everything could be implemented.

At this time, the two walked to the exclusive R&D room of the steam engine, Li Yuan carefully followed Yang Guang's words, R&D is even more important than production, so neither gunpowder nor steam engine R&D has been left behind.

There was a strange-shaped iron bump in the empty factory, which Yang Guang had never seen before.

Let them develop on their own, and sure enough, the technology tree is still a little crooked.

Yang Guang asked them to demonstrate, but they didn't expect this strange shape, and after the ignition below, a simple piston movement really began, at least in principle, there is nothing wrong, but this style and conversion efficiency are not actually used.

"Call all the main engineers who made this thing."

More than a dozen people came from Ulala, the older ones in their fifties and sixties, and the younger ones in their teens.

"First of all, you have to seal the steam engine, and the inside has to be a confined space, otherwise the steam will be useless when it comes out, and the contact area should 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 the situation inside?" ”

"What's the use of seeing? We're asking him to work now, and as long as he can work, why don't you see it? ”

"Oh~" The boy jotted down the essentials in his own essence.

"Directing steam into a confined space, there is a lid-like device connected to a connecting rod, which can be called a piston, a movable stopper."

At this time, the young man spoke again: "Can you set up a small hole, a pressure relief hole, the switch of the pressure relief hole is connected to the connecting rod, here the switch is opened when the piston is pushed to the top, the steam is discharged, the piston falls, and after it falls, the steam is turned off and continues to pressurize, 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 amazement.

That's when I told you about the piston, and you jumped directly to the reciprocating piston for me?

"What's your name?"

"Back to Your Highness, my name is Li Chun."

Yang Guang only felt that this name was familiar, and suddenly said with a shocked face: "Where are you?" ”

Li Yuanlai helped him introduce him: "Your Highness, don't look at this Li Chun's young age, but he is the champion of the first craftsman competition held by Nanxi girl, at a young age, the craftsmanship and ideas are extraordinary, the people of Lincheng, Xingtai, Hebei, and many craftsmen here are also skilled craftsmen who stand out in this competition." ”

Yang Guangru has obtained the treasure, if nothing else, this should be the Li Chun who built the Zhaozhou Bridge.

The pioneering use of arc arch bridges to build Zhaozhou Bridge, without any basic knowledge of mechanics, leapfrog the use of advanced construction concepts, this kind of talent into their own workshop team, such as a treasure.

And now Li Chun is only a teenager, and it will take more than ten years for him to build the Zhaozhou Bridge, if it were him, the steam engine should have a much greater chance, and his head is very useful.

Yang Guang immediately said: "You draw a drawing, I'll take a look." ”

Li Chun began to paint, took out his own album, and began to think about how to make it more feasible
