Winter goes and spring comes.

For most people, spring is the season for sowing, but this year's spring is indeed a season for harvest for many people.

On a small coal mine in the western suburbs, there were a group of people standing, but not those shirtless coal workers, but wealthy businessmen in luxurious clothes.

They stood in front of a large hanging lever, watching the lever swinging up and down without blinking, driving the gear, which drove a large wooden rotor to rotate, and the rotor was connected to a handle, shaking up and down with the handle, but they saw constant water flowing from an iron pipe into the ditch.

"Although the amount of water is not large, it won't take long to pump water so much that the accumulated water can be drained."

"Baby! This steam engine is really a baby! It's simply omnipotent."

"Who do you know why this water can be pumped up?"

"I heard that this is the latest invention of the Sixth Academy of Sages, called it a water pump. It has applied for a patent at the Patent Office and has been bought by the Zhang family."

"Let's go and ask Brother Han."

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

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

"right."

"Why will the water come up after one go up?"

Han Yi smiled and said, "This is all based on the principles of our Six Sages. In professional terms, it is because of air pressure."

"What is air pressure?"

"This will be unclear at the moment, but recently our Sixth Academy of Sages may publish an article in the Tang Dynasty Daily to explain the principles. You can see it yourself."

"There is still a principle?"

"Of course, all the inventions of our Sixth Academy of Sages are based on the principles of Sixth Studies of Sages."

These businessmen were fooled by Han Yi and stunned.

Yuwen Xiumi suddenly asked, "Brother Han, why are you doing squatting here alone?"

Han Yi said oh and said with a smile: "I am observing this channel. Don't you think the layout of this ditch is very exquisite? There are also special sewage drainage ditches."

Yuwen Xiumi said: "This is normal!"

Han Yi said again: "Is that so? I thought I could just slap it casually!"

"How can that be done?" Jia Fugui suddenly said: "If sewage is discharged into other people's farmland, then this matter will be too small, and at worst, it will be punished. Moreover, the rivers in Guanzhong are already weak, and if they are blocked by the sludge, it will be even worse!"

Han Yi asked, "You all think so?"

The businessmen nodded one after another, and looked at Han Yi with great confusion, as if asking, aren't you talking nonsense?

It turned out that in the early Tang Dynasty, we attached great importance to the management of rivers, because Chang'an lacked food, which was the lifeblood of the people in Chang'an. Especially after the canal, merchants often donated money to the court to clear the rivers. Moreover, before the Tang Dynasty, it was a small peasant economy. The law was to prevent all acts of damaging farmland. Officials could not buy the people's fields at a low price, let alone occupying them. It was okay to dig this coal or not, and the food could not be left out. If you want to discharge sewage indiscriminately, if you get into other people's farmland, the people in that village might starve to death, because no one has any other source of living, and they are all from landlords, and they attach great importance to this aspect.

The rulers also like mountains and rivers very much and are superstitious about Feng Shui. If this sewage runs to the place where the family grows, then they may fight you desperately.

Not to mention, the Yuan family is very ecology-conscious, because the Yuan family used to be famous for gardens. But in the final analysis, this is actually influenced by Confucianism. Even if they are merchants and put interests first, some things still have to be taken care of, and they are willing to spend more money to dig these ditches.

Interesting! Interesting! Han Yi nodded with a smile, and suddenly waved to the neatly ordered pump, "Madam, how about it?"

Yuan Mudan came over and said, "The cost is not calculated yet, but no matter what, it still needs to be used. If you don't use it, you will never be able to use it."

He Ruohan sighed and said, "You Yuan family is a choice. Even if we are willing to use it at a loss, we can't use it!"

Yuwen Xiumi immediately said, "That's not true. I said Brother Han, are you a little biased? You should be better off in everything. The Sixth Court of the Sage is from the court."

They have a lot of opinions. We donate together. Why is the Yuan family the first to use the steam engine?

Han Yi laughed and said, "Of course I have to look to my wife. Is there any problem?"

Awkward!

Those businessmen were both smiling and crying when they faced Han Yi’s domineering answer!

The answer is, there is no problem, you are your brother.

Yuan Mudan felt a little embarrassed and said, "Don't listen to his nonsense, he is not directing me, he is thinking about you."

Yuwen Xiumi asked, "What does Mrs. Mudan say this?"

Yuan Mudan said: "There are very few coal and iron mass production nowadays. Even if the Sixth Academy of Sages develops more steam engines, you won't use them, because it is not cost-effective to use them. Not to mention how much it costs to buy a steam engine, the coal cannot be burned. Therefore, it is necessary to produce enough coal and iron to make the steam engine popular. The steam engine should first be used for mining and smelting."

"Yes! Yes! " Yuwen Xiumi nodded and said, "Mrs. Mudan's words are really reasonable!"

The other merchants also nodded.

Without iron or mine, this steam engine cannot develop.

"Madam, why do you tell them businessmen? They only have money in their eyes. Let's go there and study with Wang Ping."

Han Yi was not shy at all and hugged Yuan Mudan and walked towards the steam pump.

Humph! Aren’t you and your wife also businessmen?

The merchants said in their hearts at the same time.

"Wait a minute, Brother Han!"

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

Han Yi said: "What's the matter?"

Jia Fugui said excitedly: "It is our first clock that has been developed, and we want to present it to Your Majesty."

Han Yi said in surprise: "Is that true?"

Jia Fugui nodded and said, "It's also a blessing for the steam engine. If it weren't for the emergence of the steam engine, we wouldn't know how to produce those precise parts. It is precisely because of the steam engine's production technology that our clocks can become smaller."

Han Yi smiled and said, "Okay, we'll go and have a look later."

"All right."

The other businessmen looked at Jia Fugui with contempt.

They all knew why Jia Fugui offered the clock to Li Zhi, not to flatter him. He flattered Li Zhi, and it probably took less than an hour for Li Zhi to forget that he wanted to use the royal family as the spokesperson to promote such clocks among the aristocratic group.

You don’t have to think about it, and it is definitely very expensive to produce clocks nowadays, and only wealthy people can afford it. Ordinary people don’t have to think about it, just look at the clock tower.

However, the emergence of boring machine technology has enabled many ideas to be realized.

A typical example of a clock.

However, when Han Yi returned to the city and saw a landing clock that was about the same height as him, he felt that he was being fooled!

"Is there anything wrong with Shangshu Ling?"

"No, it's very good, wow, it's really much smaller!" Han Yi praised against his will, but he also knew that this was already very amazing. It was indeed much smaller than the clock on the clock tower, and said, "You have really exhausted your mind. They used the best sandalwood and glass. Haha, this must be very expensive."

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

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

"Others won't show it, but if you say it, Brother Han, of course, that's OK."

Qiu Mo hurriedly opened the back of the clock.

Han Yi frowned and looked at it, with a glimmer of joy in his eyes. Even when he saw the clock just now, he did not say that he showed his true joy.

However, Li Zhi did not want this clock.

First, he basically couldn't see it clearly and was too lazy to read it. Anyway, he was artificially reported the time. Second, he thought the clock was ticking and noisy.

But he couldn't give it back to Jia Fugui, and he always had to help others do publicity, so Han Yi carried the clock to the Zhengshi Hall.

He also fooled Zhang Wenguan and the others, saying that the emperor was very considerate of us and that this best thing would be used first.

Dongdongdongdongdongdong!

Dangdangdang!

The clock tower and the clock inside the house ring almost at the same time.

“It’s really on time!”

Li Hong is relatively young and thinks this feeling is very wonderful.

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

In fact, they are all used to watching the time in the clock tower, so they think it is very convenient. Li Zhi doesn’t need to pay too much attention to the time. As long as he has time, others will be free. Moreover, he manually reports the time, so he doesn’t need to watch it himself, so he has more eyesight.

Han Yi smiled and said, "Everyone, you can customize this kind of watch now. Is it a little more expensive? For you, it's still a drop in the bucket."

Cui Jieren smiled and said, "It turns out that Shangshu Ling was entrusted by someone to come here to promote this clock!"

Han Yi said: "Nonsense, this is a selfless expression. I will share the good things with you."

Li Hong laughed loudly when he heard this.

Zhang Wenguan suddenly said, "Shangshu Ling, you are the leader of all officials, but in the past few months, you have been busy with these things all day long and even rarely come to meetings. How can this be more concise!"

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

Han Yi said: "Zhang Shizhong, you misunderstood me. I'm doing it all my spare time. Actually, I've been very busy all the time."

Li Hong said curiously: "What are you busy with recently?"
