After Chinese New Year's Eve.

Time has come in a blink of an eye, February 14 of the fourth year of Zhenguan.

This day is Li Chengqian's birthday, and it is also the day he chose to set off.

Because the Qianzi battalion went to the Hetao area under the leadership of Cheng Huailiang as early as two days ago.

Therefore, this time with Li Chengqian, only the servant girl Wuwu and the eldest grandson Chong, who had just participated in the autumn festival, set off with Li Chengqian.

At noon, the cyan carriage they were riding in also slowly drove out of Chang'an City, all the way north.

Until the shadow of the carriage vanished.

Li Shimin, who was standing at the head of Chang'an City, did not look back.

The eldest grandson Wuji brought a fur cloak and draped it over his body.

"Your Majesty, the cold of the spring cold hurts the most, you have to take care of your body."

"Hmmm......"

Li Shimin looked at the direction where the carriage disappeared and said, "In the past, when this kid went out of Chang'an, he would say hello to me. ”

"But this time, this kid didn't even say hello, it's really a lack of cleanup."

Put in order?

I'm afraid that Your Majesty, you can't bear it at all now.

Eldest Sun Wuji chuckled: "When His Highness comes back, His Majesty will have time to clean him up." ”

"But come to think of it, Your Majesty should not be able to bear it, and it won't be long before he will go to Mobei Province to see him."

Hearing this, Li Shimin deliberately straightened his face and said, "What are you doing with him?" Let him be angry with me again? ”

"I don't have that good temper to deal with him, it's good if he leaves, and someone in the province will be angry with me again."

Sure enough, Li Shimin is still Li Shimin.

It's still like this to save face.

The eldest grandson Wuji shook his head slightly, and smiled at Cheng Yanjin on the side.

The eldest grandson Wuji couldn't help but sigh: "Time is in a hurry, and in a blink of an eye, the children have all grown up." ”

"The naughty appearance of these three guys is still in front of me."

"Who's to say it isn't."

Cheng Yanjin sighed lightly and said, "I old Cheng, when I beat my son, it seems to be like what happened yesterday." ”

"But if you think about it, it was a few years ago."

The three looked at each other, then smiled on their backs.

Whether it is the three hooligans of the Tang Dynasty or the Iron Triangle of the early Tang Dynasty, they all seem to be old in a blink of an eye.

Among the three, the eldest Cheng Biting Jin, even has a little white xia in his beard.

The youngest Li Shimin also had wrinkles at the corners of his eyes because of years of hard work.

Wait until the backs of the three gradually disappear in front of people's eyes.

The meaning of desolation is still born.

……

The book says briefly.

In late February, Li Chengqian arrived in the Hetao area.

When he came here, Liu Min had already arranged everything he had explained.

At Li Chengqian's request, Liu Min hired a total of 1,000 laborers.

Among them, there are 300 Tang people, and the remaining 700 are all composed of old Turkic people, that is, 'New Tang people'.

Li Chengqian's purpose in doing so is the same.

It is nothing more than to try to integrate the New Tang people into the Tang people's group as much as possible.

looked at the more than 1,000 people in front of him.

Li Chengqian climbed onto the wooden platform and said loudly: "From today onwards, we will all spend a year or even a few years together. ”

"I have no other pursuits, only fairness and justice."

"Whether it's a Tang Dynasty or a New Tang Dynasty, I won't favor anyone, let alone treat anyone lightly, everyone is the same."

"Before we get to work, there are a few rules that I have to make clear to everyone in advance."

"First of all, everyone's salary, I think Master Liu has told you before, my way of paying wages is different from others."

"Plough one acre of land, and if you pass the inspection, you can receive thirty copper plates."

"If you build a ten-step ditch and pass the inspection, you can still receive thirty copper plates."

"I don't care how many ditches you've built or how much you've ploughed today."

"I'll only pay you according to your actual work quota."

"In my place, those who can work more, those who can earn more, if you have the ability to complete all the work in one day, I can also afford to pay you."

"Of course, it has to be by my standards."

"And after the fields are built, I will assign jobs according to the amount of labor they earn."

"If you do very well, then when I assign you a job, I may put you in a position that is light and earns a lot of money."

"If you perform very poorly, then I'm sorry, I can only give you a grassroots job."

"If you are not satisfied, you can leave directly, I will not stop you."

Li Chengqian looked at the crowd: "Do you have any opinions?" ”

"Nope!"

Everyone said in unison.

Li Chengqian nodded and said: "Then the next is the second one, during the labor period, no fighting, no forming a party, no bullying others." ”

"If anyone dares to cause trouble in front of me, whether it is the beater or the beaten, both leave, do you have any opinions?"

Li Chengqian has brought into play his advantages from the 21 st century.

The same set of principles that govern the company has been copied to this era.

Perhaps, in that very enlightened era, some people would complain that such norms were unfair.

But those who are capable work more, and those who are strong are inferior to those who are mediocre, which will always be an eternal truth.

With Li Chengqian's order.

One thousand laborers went to the camp opened by the Qianzi Camp to collect working tools.

Then, under Li Chengqian's arrangement, he began to do things in an orderly manner.

He divided the 1,000 people into three batches.

The first people went to build large ditches to bring water into the Yellow River.

The second group went to build paddy fields where rice and wheat could be grown.

The third group went to plough the ground and build dry fields.

Looking at the little bit of land that had been reclaimed, a smile gradually appeared on Li Chengqian's face.

The happy time of the cottage bear is about to begin......

……

Labor does things.

It is impossible for Li Chengqian to be idle.

When all the work was underway, he returned to the makeshift camp and began to work on the drawings.

He plans to build dozens of irrigation canals in this vast farmland.

The aqueduct may seem simple, but it's actually very complex.

If well designed, the water can flow through the large ditches that bring water into the Yellow River and flow into each ditch for irrigation of farmland.

In addition, the traditional farmland irrigation canals have a low degree of intelligence, and all of them need to be pumped and discharged manually.

Therefore, it is particularly important to seek a farmland irrigation canal with a high degree of intelligence that can automatically drain and inlet water.

In this era when there is no machinery and no industry, it is very difficult to find an automated drainage method.

But this can't stump the science and engineering man Li Chengqian.

His idea was simple: to build a simple machine that could pump water automatically at the entrance of the main canal and the branch canal.

In this way, a steady stream of water can be fed into the branch canals to irrigate the farmland.

In the past, people used water wheels to irrigate their fields.

And the waterwheel existed as early as the Eastern Han Dynasty.

And it has been proven by history that sooner or later this thing will be eliminated.

Therefore, Li Chengqian did not disdain to use this outdated old guy at all.

After all, he was someone who could study even a wind mill or a propeller boat.

Can't you just make a wind pump?

Thinking of this, Li Chengqian said he would do it.

Within two days, he handed over the first draft to the craftsman.

These craftsmen were Zhang Carpenter and others brought by Li Chengqian.

These people have long been accustomed to Li Chengqian's whimsical ideas.

Therefore, after reading the drawings, I did not hesitate and started construction immediately......
