Han Jiang understood.

This matter should be placed in the period of the current Emperor Taishang, and since it has nothing to do with the Han family at the moment, the Han family stopped and stopped investigating after checking some of them, not wanting to cause trouble.

Han Jiang asked in a low voice, "No benefit?" ”

Ying was amused, and asked rhetorically: "It's good, there's no news when you come back, even if our sisters don't care, but some people rush up, just because it's not good, our family's eyes are bright." ”

Han Jiang also couldn't stop laughing.

Cai Zai's side urged at this time: "It's almost time, go back to the eldest lady, calculate that this fire should also wake up, aren't you in a hurry to watch?" ”

Han Jiang looked at his body, then at his hands, and after thinking about it, he stood up: "I'll come back later." ”

In my previous life, I had a child for the first time.

Biological.

The two adopted don't count.

Han Jiang wanted to hug the child, but he didn't hug it, he asked people to block a veil, and looked at his son Han Lichen, who had just woken up, through the veil.

"Don't hug it, I didn't change my clothes when I came back from outside, and I changed it after bathing and changing, so I didn't have to take anything unclean home."

Not clean, in this era the word mostly refers to ghosts.

Han Jiang means simple germs and the like.

Qian Xinyao was a little tired, and she didn't want to ask about these idle things, so she ordered someone to arrange bath water for Han Jiang and the like.

Common sense says that when you just go home, you must wash the dust.

In the past, Han Jiang didn't understand the saying "washing dust", but after traveling in the Great Song Dynasty for so long, he understood.

When I came back from sea, my face was full of salt particles.

Come back from the land, don't go too far, a hundred and ten miles of road is guaranteed to become a native man, there is no clean road in this era.

At dinner, Han Jiang saw the Cao sisters, and their eyes were still red.

Han Jiang didn't dare to ask half a word.

The only thing she knows is what Ying told her before, Qian Xinyao will ruthlessly clean up the Cao family sisters.

In other words, it is really ruthless.

Before thinking about it, Qian Xinyao and Cao Ruoying, who was originally the third girl of the Ge family, were very good handkerchiefs, and they would be correct.

The two girls of the Cao family were also wronged to death.

Han Jiang has never taken the initiative, what else can they do, they are all famous daughters, and they have to be reserved.

Anyway, this is back in Lin'an, life is to be lived, and the rules are to be observed.

At night, Han Jiang stayed in Qian Xinyao's house and didn't leave.

Qian Xinyao had to call someone to drive Han Jiang away.

The reason is very simple, hurry up and go to Cao Ruoying's house, this is the rule.

However, Han Jiang took out a small thing, and Qian Xinyao fell instantly.

A beautiful little bamboo tube.

What is the small bamboo tube, this thing can be made by any craftsman apprentice in Hanfu, but it is such a small thing, which completely made Qian Xinyao fall.

Han Jiang blew on the side with his mouth, and the small bamboo tube began to reciprocate continuously, moving like a wind drum in a steel mill.

Interesting?

Qian Xinyao's heart was full of doubts.

Han Jiang smiled and aimed the end of the small bamboo tube at the tea stove that had just been boiled, the copper kettle on the tea stove sprayed hot gas, and then the small bamboo tube began to reciprocate at high speed.

At this time, Han Jiang took out another set of parts.

A curl wheel.

The reciprocating small bamboo tube drives the crankwheel, then drives the small bamboo wheel in front, and then drives it by the small belt, and the small fan begins to rotate.

Qian Xinyao hugged Han Jiang's neck tightly with both hands, staring intently.

"This, this, what is this?"

Han Jiang replied: "This is the era, the creation of an era of gods." I've always known about it, but never thought of giving it to anyone. When I was in Jiaozhi, I saw a lot of machinery that made me feel very powerful, and the production of steel mills has been improved by several times the efficiency of wind and water power. ”

Qian Xinyao didn't doubt Han Jiang's words.

It's just that she can't understand what this thing is, it just feels very magical.

Han Jiang asked: "Lady, what is the power source of the water mill?" ”

"Water is the flow of water. The stronger the current, the more powerful the water mill is. ”

Answer correctly.

Han Jiang asked again: "Look at this little thing, what does the motivation come from?" ”

Qian Xinyao observed this structure very seriously: "It's qi, blowing." No, it's not. It's water. It doesn't seem right. ”

After all, Qian Xinyao's knowledge is interesting, and this thing is a bit difficult for her.

But not so much as to completely stump him.

Han Jiang wanted to say that Qian Xinyao refused, and she wanted to study it herself.

The joy of self-study is indescribable.

Of course, only poor Cao Ruomu washed himself and waited stupidly in the house, but the third watch day had passed, and Han Jiang still hadn't been seen.

But when Lan Xiang came over and said, "The lord and the eldest lady are discussing knowledge, and they won't be here tonight." ”

Discuss the words of learning, Cao Ruo Muxin.

She had no doubts at all.

Let's talk about Qian Xinyao's house.

After a full hour, Qian Xinyao finally figured out what the truth was about the thing in front of her.

It's a pot.

The water in the pot is boiled with coal, and the power of water vapor is very strong, which can push the lid of the copper kettle open, so press the lid tightly to let the water vapor spray out from the spout, and this force can push the piston structure of the small bamboo tube to move back and forth.

It's just that......

Qian Xinyao asked: "Husband, why don't you add a double pipe and let the steam blow at both ends?" ”

Han Jiang was surprised to hear such a question, thought for a while and replied: "I've heard that this is called a monotube, and then there are multi-expansion types, steam turbine types, this thing goes deeper into research, there is no end." ”

"Yes, how strong?" Qian Xinyao was a little excited.

Han Jiang held his chin and thought about it: "Well, how strong is it." Don't you want to go to heaven? When this thing is studied to a certain extent, God will definitely be able to use it. I think, pushing a boat with 3,000 materials to run three times faster than now, I don't know if you are satisfied, or pulling tens of thousands of stones to run to Jingzhao for a day and a night, are you satisfied? ”

Qian Xinyao nodded her little head very seriously: "Satisfied, very satisfied." According to Jiang Lang, this thing seems to be very difficult to study and not easy to make? ”

Han Jiang laughed: "It's not easy, the three million guan that the Wancheng army got from the imperial court is used in this matter, at most it can be heard, if it is done well, it will be louder, and if it is not done well, the sound will be almost inaudible." I've always been reluctant to take it out because it's so hard to make. ”

Qian Xinyao asked rhetorically: "Why do you want me to know now?" ”

Han Jiang replied: "In Qiongya, I saw that there are iron blowers in the steel mill, which are driven by hydraulic power, so I can think that we already have pistons, seals and other means in our hands now." It's also for you to have some fun, this thing is slowly studied, and a little progress in three and five years is not slow. ”

After Han Jiang answered, he leaned over to Qian Xinyao: "What is a steam engine, let me explain it like this, in the current world, whoever has the high-end technology of the steam engine and successfully applies it to his own territory will have the power to conquer the world, and it is under the sun...... World. ”
