"Control valves? How much vapor is controlled? Duanmu Rong, who was deep in thought, was suddenly stunned, and suddenly looked at Li Zhao, a strange and excessively young person.

"Exactly." Li Zhao smiled, and then pointed to the pot, "You can improve it." ”

Duanmu Rong didn't act immediately, but fell into deep thought, took a deep breath for a dozen times, and suddenly the whole person stirred, and he didn't know the strength there, so he picked up the pot and walked inside.

There, the forged forge.

Li Zhao didn't mean to follow, and waited on the side.

Seeing Duanmu Rong's such impolite behavior, Han Shaofu smiled awkwardly and said, "General Li, let you see it, Duanmu Rong is this kind of character, and when she works, sometimes she doesn't even pay attention to me." ”

Having said this, he couldn't see the disgust in Han Shaofu's eyes, but was a little happy.

Of course, Li Zhao does not care about her rude behavior, in fact, this kind of behavior is not rude, but a manifestation of dedication and obsessiveness to the post.

This kind of behavior should be recognized.

"No problem! I love her style. Li Zhao waved his hand, and it could be seen that he was telling the truth.

Han Shaofu was relieved, and beckoned a few people to go inside, of course, to help Duanmu Rong go.

"Come on, come on, it will take some time to renovate the boiler, how about we have some tea?" Han Shaofu knew the difficulty of iron transformation, so he greeted Li Zhao and said that he was Shaofu and was in charge of the weapons manufacturing office, so there was naturally a special office here.

Li Zhao was surprised to hear it, if his guess was right, Daqin did not rise to drink tea, how could Han Shaofu also know how to treat guests with tea.

In fact, what Li Zhao didn't know was that all this was his credit.

Since the last time the emperor came to Chang'an Township, he drank the tea, and he felt good, so he asked people to go to Chang'an Township every other day to ask for it.

Daqin originally had the existence of tea, but it was only used for medicinal purposes, and it was studied at the moment, and soon a way was studied, so it became popular among the powerful to drink tea, and it was also used for reception.

Li Zhao was just surprised, and he didn't ask much, so he walked with Han Shaofu.

Half a cup of tea, chatting for a while, someone came to report, saying that the boiler renovation was completed, and the two adults were invited to watch.

Li Zhao was a little surprised, it was estimated that it would be transformed in less than an hour, Duanmu Rong's efficiency is really good, of course, it can also be seen that she is highly talented, and she can understand it at all.

He wondered if the woman would make a prototype of a cylinder.

Soon, the two came to the place just now, and at the moment they were surrounded by a bunch of people, looking curiously at the newly renovated boiler, Duanmu Rong stood at the front, stroking with a sense of accomplishment, as if touching his beloved daughter.

"Two adults have arrived."

So, a lane was made on both sides, and Li Zhao did not push, and was the first to approach the boiler.

The surface of the boiler is still the same as what I saw before, the difference is that there is an extra bar above the upper boiler, colluding on both sides, which should be the control valve.

Below, there is a hole, it should be an air hole, although it is set up a little awkwardly, Li Zhao observed it and felt that it should be able to be used, however, there is no external force, and this air hole cannot be closed in time when there is a vapor discharge, and it is no different from the previous bar.

So, he pointed to the valve gate on the air hole, "This, you plan to operate it manually?" ”

Duanmu Rong was stunned, maybe she didn't expect this, the excitement just now stopped abruptly, and she was contemplative.

Li Zhao couldn't laugh or cry, although this woman has mature beauty, she is not good at words, and often frowns and ponders, as if others owe her hundreds of gold.

"In fact, you can connect this valve to this bar, and the movement of the bar will drive the valve to operate automatically, so won't it solve the problem of human operation?"

He still knows a little about the operation principle of the steam engine with memories of his previous life.

"Is that so?" Duanmu Rong's frowning brows suddenly relaxed, and she cast a more curious glance at Li Zhao, but it was only for a moment, and she moved to the boiler one by one, and kept gesturing with her hands.

This is the process of comprehension, and Li Zhao has no intention of bothering.

Often some things are left to talk too much, it is better to use your own brain and hands, so that the effect is the best.

After a while, Duanmu Rong carried the boiler inside, and this time those craftsmen were much more diligent and busy moving together.

Li Zhao knew that she was going to transform again.

Smile with satisfaction.

As far as he just observed, the boiler that Duanmurong has renovated has made some progress, the cylinder is replaced by the upper boiler, and the slide valve room is not very compliant, but it can be used as a control valve.

Of course, in order to be able to recycle water, a condenser is also needed, this is not in a hurry, Duanmu Rong is really transformed into a prototype of a steam engine, which shows that she is very talented, and then take out the steam engine drawings, the appearance of the steam engine is just around the corner!

Li Zhao is looking forward to it more and more.

Originally, it was best to be responsible for the manufacture of steam engines to Ah Chao, after all, it was his own industry, but Qin Shi Huang had already asked the Mo family to study it, so he couldn't hide it privately, otherwise it would bring unnecessary trouble, and he didn't want to trouble coming to the door.

Of course, there will be gains and losses, and perhaps he will gain some benefits from them.

After another half of tea, Duanmu Rong was transformed again, and this time, Li Zhao had to look at her differently.

This automatic valve is really talented, and it is somewhat similar to the parts of the steam engine in the previous life.

"Try it!" Without waiting for Duanmu Rong to make a move, he was the first to speak.
