Winter goes to spring.

For most people, spring is the season of sowing, but this year, for many people, it is indeed the season of harvest.

On top of a small coal mine in the western suburbs, there stood a group of people, but not shirtless coal workers, but wealthy merchants dressed in luxurious clothes.

They stood in front of a large hanging lever, and watched without blinking an eyelid as it swung up and down, and drove the gears, which drove a large wooden wheel to turn, and the wheel was connected to a handle, and as the handle swayed up and down, they saw that water flowed into the ditch through an iron pipe.

"Although this amount of water is not large, it will not take long for such non-stop pumping day and night to drain the stagnant water."

"Baby! This steam engine is really a treasure! It's almost omnipotent. ”

"Do any of you know why this water can be pumped up?"

"I heard that this is the latest invention of the Sixth Academy of Sages, called a water pump, which has been applied for a patent in the patent office and has been bought by the Zhang family."

"Let's go ask Brother Han."

These merchants immediately ran to the ditch and found Han Yi.

"Brother Han, I heard that this water pump was invented by your Sage Sixth Academy?"

"Yes."

"Why does this water come up this time and down?"

Han Yi said with a smile: "This is all based on the principle of our sage's six learnings, in professional terms, because of air pressure. ”

"What is air pressure?"

"This will not be explained clearly for a while, but in the near future, our Sage Sixth Academy may publish an article in Datang Daily to explain the principle, and then you can see for yourself."

"And the principle?"

"Of course, all the inventions of our Sage Six Academies are based on the principles of the Sage Six Learnings."

These businessmen were stunned by Han Yi.

Yuwen Xiumi suddenly asked, "Brother Han, what are you doing here by you?" ”

Han Yi sighed and said with a smile: "I'm observing this channel, don't you think the layout of this ditch is very exquisite?" There are also special sewage ditches. ”

Yuwen Xiumi said: "This is normal! ”

Han Yi said again: "Really? I thought it would be just a casual lineup! ”

"How's that going to work?" Jia Fugui said suddenly: "If the sewage is discharged into other people's farmland, then this matter can be big or small, and you will face punishment at the worst, and besides, the river in our Guanzhong is already weak and can't help the wind, if it also makes the sludge clogged, it will be even worse!" ”

Han Yi asked, "You all think like this?" ”

Those businessmen nodded one after another, and they all looked at Han Yi in confusion, as if asking, aren't you talking nonsense.

It turned out that in the early Tang Dynasty, it was very important to pay attention to the governance of the river, because Chang'an lacked food, and the river was the lifeblood of the people of Chang'an, especially after the canal, merchants often donated money to the imperial court to dredge the river. Moreover, before the Tang Dynasty, it was a small peasant economy, and the law was to prevent all acts of damaging farmland, and officials could not buy the people's fields cheaply, not to mention occupying it, it was okay if the coal was not dug up, and the grain could not be without, and you had to discharge sewage indiscriminately, in case it went to other people's farmland, the people of that village might starve to death, because everyone had no other source of livelihood, and they were all landlords, and they all attached great importance to this aspect.

And the rulers are also very fond of mountains and rivers, and superstitious Feng Shui, if this sewage runs to the land of other people's families, then they may fight with you.

Not to mention the Yuan family, they care for the ecology very much, because the Yuan family used to be famous for its gardens. But in the final analysis, this is actually also influenced by Confucianism, even if they are businessmen, they put profit first, but there are some things that they still have to be afraid of, and they are willing to spend some more money to dig these ditches.

Interesting! Interesting! Han Yi nodded with a smile, and suddenly beckoned to the neat pumping machine: "Madam, how is it?" ”

I saw Yuan Peony come over and said, "It's not a cost yet, but no matter what, you still have to use it, if you don't use it, you will never be able to use it." ”

He Ruohan sighed and said, "Your Yuan family has a choice, even if we are willing to use it at a loss, we can't use it!" ”

Yuwen Xiumi immediately said: "But isn't it, I said Brother Han, are you a little biased, everything is good for the Yuan family first, the Sixth Court of the Sage is the imperial court." ”

They have a lot of opinions, we donate together, why did the Yuan family use the steam engine first.

Han Yi smiled and said, "Of course I want to face my wife, is there a problem with this?" ”

Embarrassed!

In the face of Han Yi's domineering answer, those businessmen didn't laugh or cry!

The answer is, no problem, you are the elder brother.

Yuan Peony was a little embarrassed, and said: "Don't listen to his nonsense, he is not facing me, he is thinking about you." ”

Yuwen Xiumi asked, "What did Mrs. Peony say about this?" ”

Yuan Peony said: "Nowadays, the mass production of coal and iron is very small, even if the Sixth Academy of Sages develops more steam engine applications, you will not use it, because it is not cost-effective to use, not to mention how much it costs to buy a steam engine, this coal can't afford to burn, so you have to produce enough coal and iron before the steam engine can be popularized, and the steam engine should first be used for mining and smelting." ”

"Exactly! Yes, extremely! Yuwen Xiu nodded and said, "Mrs. Peony's words are so reasonable!" ”

The rest of the merchants nodded their heads as well.

Without iron, without mines, the steam engine could not be developed.

"Madam, why are you talking to these businessmen, they only have money in their eyes, let's go over there and study with Wang Ping."

Han Yi was not shy at all, and walked towards the steam pump with Yuan Peony in his arms.

Hum! Aren't you also merchants?

The merchants said at the same time in their hearts.

"Wait a minute, Brother Han!"

Jia Fugui suddenly remembered something, hurriedly chased after him, and said, "Brother Han, there is something I almost forgot to tell you!" ”

Han Yi said: "What's the matter?" ”

Jia Fugui said excitedly: "Our first clock has been developed, and we want to dedicate it to Your Majesty." ”

Han Yi was pleasantly surprised: "Really? ”

Jia Fugui nodded and said: "This is also thanks to the steam engine, if it weren't for the appearance of the steam engine, we wouldn't know how to produce those precision parts, it is precisely because of the production technology of the steam engine that our clocks can become smaller." ”

Han Yi smiled: "Okay, let's go and see later." ”

"Okay, okay."

The rest of the merchants looked at Jia Fugui with disdain.

They all know why Jia Fugui dedicated the clock to Li Zhi, not to pat the horse, he patted Li Zhi's ass, it is estimated that it will not take an hour, Li Zhi forgot, he hopes to use the royal family as a spokesperson to promote this kind of clock among the aristocratic group.

You don't have to think about it to know that the production of clocks and watches must be very expensive nowadays, only the rich can afford them, and ordinary people don't have to think about it, just look at the clock tower.

However, the advent of boring machine technology has made many ideas possible.

A typical example of a clock.

However, when Han Yi returned to the city and saw a floor clock about the same height as himself, he felt that he had been tricked!

"Shang Shuling, is there anything wrong?"

"No, that's good, wow... Sure enough, it's a lot smaller! Han Yi praised it very unwillingly, but he also knew that this was already very remarkable, compared to the bell on the clock tower, it was indeed much smaller, and said: "You guys are really exhausted, you use the best sandalwood, and you also use glass, hehe, this must be very expensive." ”

Jia Fugui hurriedly said: "This is dedicated to Your Majesty, of course it can't be too casual." ”

Han Yi nodded and said, "Can you let me see the structure inside!" ”

"Others don't show it, but Brother Han, if you say, of course it's okay."

Qiu Mo hurriedly opened the back of the clock.

Han Yi stared at it, the joy flashed in his eyes, even when he saw this clock, he didn't say that he showed sincere joy.

However, Li Zhi did not ask for this bell.

First, he basically can't see clearly, and he doesn't bother to look at it, anyway, there is a manual time, and second, he thinks this clock is ticking and noisy.

But he couldn't return it to Jia Fugui, he always had to help others do publicity, so Han Yi carried the clock to the political hall.

And fooled Zhang Wen into filling them, saying that the emperor was very considerate of us, and this best thing should be used for us first.

Knock knock!

Dangdang!

The clock tower rang almost at the same time as the clock in the house.

"It was so punctual!"

Li Hong is relatively young, and he feels that this feeling is very amazing.

Shangguan Yi also pinched his goatee and said, "It is indeed very convenient to have this clock here." ”

In fact, they are all used to the clock tower to see the time, so they find it very convenient. Li Zhi doesn't need to pay too much attention to time, as long as he is free, everyone is free, and he has manual time, so he doesn't need to watch it himself, so he needs to spend more eyesight.

Han Yi said with a smile: "Everyone, now you can order this kind of clock, it is a little more expensive, for you, it is still a drop in the bucket." ”

Cui Jijian smiled and said: "It turns out that Shang Shuling was entrusted by someone to come here to sell this clock!" ”

Han Yi said: "Nonsense, this is a manifestation of the selflessness of the Grand Duke, a good thing, I just shared it with you." ”

Li Hong laughed when he heard it.

Zhang Wenguan said suddenly: "Shang Shuling, you are the head of the hundred officials, but in the past few months, you have been busy with these things all day long, and you don't even come to meetings, what kind of system is this!" ”

Wu Meiniang, who had been silent, frowned slightly, and glanced at Han Yi thoughtfully.

Han Yi said: "Zhang Shizhong, you misunderstood me, I am doing this in my spare time, in fact, I have been very busy." ”

Li Hongting was curious: "What have you been busy with lately?" ”

"Of course, it's the Taiyuan plan, but the policy of the DPRK and China is almost the same, now it depends on how to cooperate with the businessmen, I have been discussing with the businessmen recently, and sometimes they have discussed until three or four watches in the evening before resting."

"Is that true?"

Sun Chuyue was a little unconvinced.

"Lie to you as a puppy!" Han Yi swore solemnly. I thought, that peony is also a businessman, I often talk to her until the fourth watch, no way, buddy is so strong.

If he wants to say this, Zhang Wenguan and they can't do anything about him, but Han Yi's performance during this period of time has indeed caused them a lot of discussions, and they always came to meetings before, but now they rarely hold meetings.

However, Han Yi was thick-skinned and didn't care at all, and said with a smile: "The clock has already told us that it's time to eat, even if we forget to sleep and eat, the prince has to eat." ”

Li Hong smiled but did not speak.

If you don't go to work, you can get off work faster than anyone else, if you are Li Ji's age, you can just come, but the problem is that you are now in the prime of life.

Out of the palace, Han Yi went directly to the luxurious private room in the new market, nibbling on lamb's elbow and drinking wine alone.

After a while, there was a sudden knock at the door.

"If it's Cao Bo, let him in."

"Yes."

After a while, the door opened, and I saw Cao Bo walk in and salute: "The villain has seen the proprietor." ”

"Eat one piece, I'll prepare it for you."

Han Yi pointed to the sheep elbow on the opposite side and said.

"Thank you, proprietor."

Cao Bo was also not polite, because he knew that Han Yi was not a polite person.

Han Yi asked while eating, "How about the parts I asked you to make last time?" ”

Cao Bo said: "We can already produce those parts skillfully. ”

"Good!"

Han Yi nodded, and said, "What about using a steam engine to drive a lathe?" ”

Cao Bo said: "Now the safety valve has been developed almost completely, as long as the safety can be ensured, coupled with the technology you gave us from the proprietor, I think it should not be a problem." ”

Han Yi snorted, picked up the handkerchief on the table, wiped his mouth, took out a drawing from his briefcase, put it on the table, and said, "This is your next task." ”

Cao Bo took it and looked at it, and sighed, "This is a bit similar to some parts of a clock." ”

Han Yi said with a smile: "I also saw the clock, and I realized that the technology in this area has made great progress, but these parts are more delicate, and you have to hurry up." ”

"Yes, we'll step up R&D."

After lunch, Han Yi took another nap in the house, and planned to go to the Grand Theater for a stroll, but when he went out, he met an old acquaintance.

"Wow! Sister Cao, how can I meet you anywhere? ”

Cao Xiu looked at Han Yi, who was knowingly asking, and could only cooperate: "Yes!" What a coincidence! ”
