Daqin Engineers

The name Zheng Guo is also a hydraulic engineer, and Wang Jian transferred the water to flood the beams. Who else is the one who repaired Zheng Guoqu?

Zheng Guoyi's eyes widened when he heard Shen Bing's name.

"Couldn't it be the Shen soldier who made the waterwheel and overturned?"

Yang Duanhe answered with a smile:

"Who else could he have?"

"Use your husband to help the water workers, you won't insult the water workers!"

Zheng Guo hurriedly said:

"Of course."

"I have heard about the name of my husband for a long time, and I saw it today as a talent."

Shen Bing hurriedly responded:

"Dare not dare."

This Zheng Guo is one of the rare people in this era.

If you don’t know it, you think Zheng Guo just built a canal... Will it be done with manpower and time?

But if you really understand it, you won't think so.

Dan is located in inland areas with high evaporation rates, which often have problems with salinization. The reason is that the salt in the water evaporates but remains.

Although fresh water has very little salt, it can't stand the accumulation of time... Over time, the land will be salinized and no crops can be grown.

Guanzhong of Qin State (the area of ​​Jingyang, Shaanxi today) is such an area. The salinization of the area is very serious, and even the nearby lakes are salty.

This problem is difficult to solve in modern times, but who can think of Qin State more than 2,000 years ago, let the hydraulic worker named Zheng Guo solve it.

There is a river in Guanzhong called Jingshui. The characteristic of this river is its high mud content.

It originally traveled north-south and then merged into the Wei River to have no effect on the large saline-alkali land in the middle.

As a result, Zheng Guo came to a magical pen... he built a canal to change Jingshui into an east-west direction to lead to Luoshui, during which several tributaries were introduced into Zheng Guo canal to make the water abundant.

This is nothing at first, it can be done by stacking people and stacking time, without technical content.

The point is...

The amount of water is precisely controlled to flow through Zhengguo Canal during the flooding period, causing the mud and sandy Jingshui to flow to the saline-alkali land below, and it will come regularly once a year.

As a result, the surface of the saline-alkali soil was covered with a layer of fertile sand...Since then, the saline-alkali soil has become a good field.

The record of this in Shiji is:

"Qu Cheng, filled with silt water, irrigated more than 40,000 hectares of brine (1.1 million mu today), and harvested one acre (100 kilograms today), so Guanzhong became a fertile field, and the year of no fierce Prosperous and powerful, the dying and the princes, because of his fate, he said "Zheng Guoqu"."

Calculating in detail, it is that Qin receives 110 million kilograms of more grain every year, so Qin has grain to destroy the six countries.

These are not important.

The important thing is...Is this method simply going through?

Modern people know that the annual flooding of the Nile in Egypt brings fertile land to the deserts on both sides of the bank.

Especially in the Qin Dynasty for more than two thousand years, before the Qin Dynasty did not know that there was Egypt or the Nile River... Some people created a Zheng Guo canal that could regularly flood the saline-alkali land every year and bring fertile soil?!

Moreover, the Nile was formed naturally, and it is said that it also gave birth to a civilization.

But the Qin people built a Nile River, an artificial Nile River...

There are various considerations such as water level difference, water volume, drainage, etc. How do you do it without accurate measurement tools?

Does it rely on the iron ruler in Zheng Guo's hand?

Shen Bing looked at the "crutch" and wanted to ask Zheng Guo, but he was worried that he would not understand what he said...Is this embarrassing the traveler?

After Zheng Guochao Shen Bing nodded in greeting, he clasped his fist to Yang Duanhe:

"General, the strategy of this water attack... I'm afraid it's not that easy."

Yang Duanhe could not help but wonder:

"Why?"

Zheng Guo ordered people to take the map, then placed it on a stone platform and pointed at the map and said:

"The chasm water system near the beam has been repaired for several generations, and it has been more than a hundred years."

"Now that the waterway has been blocked too much, it is time to stop the water to dig the silt and remove the blockage."

"It's a pity that countries have been unable to look forward to the war for years, so although the gap leads to the Yellow River, the water is small!"

"If I wait to open the embankment... I'm afraid the river will not flow into the Bian River as I waited."

"Or even though it is poured into the Bianhe River, the water is not strong enough to break down Liangjian City."

Yang Duanhe couldn't help but ask:

"Why did the hydraulics know that the estuary is in Sai?"

It's no wonder that Yang Duanhe would ask that. They hadn't reached the mouth of the Bianhe River at this time, and Zheng Guo just measured the amount of water in the Yellow River.

Zheng Guo replied:

"Wei's folk rumors say:'The chasm is clogged with mud, the water is halfway, the river is surging, and the corn is difficult to fertilize.'!

"This is a water matter. The general is busy fighting all year round. It is normal to have never heard of it."

Yang Duanhe said "Oh", then turned his gaze to Shen Bing.

Shen Bing understood.

The root cause is the large amount of sand in the Yellow River.

Because of the large amount of sand, the ditches from the Yellow River, including the Bianshui, will have mud in the river.

Therefore, if the dyke breaks and the water hits the beam, the river water is likely to spread around because of the mud blocking the mouth of the river instead of filling the Bian River and rushing towards the beam city.

Shen Bing couldn't help frowning, it seemed that he could only dig in the mud.

But digging river mud on the battlefield?

Seeing the eye contact between Yang Duanhe and Shen Bing, Zheng Guo asked in doubt:

"This plan...is it the husband's decision to fail?"

Shen Bing arched his hands and replied:

"It's the subordinate that made the water worker laugh!"

Zheng Guo looked at Shen Bing and nodded slightly, and sighed:

"The younger generation is terrible, the younger generation is terrible!"

"My husband is not only good at wood craftsmanship, but also as a general manager. He is really the pillar of my great Qin..."

The voice was interrupted before the voice was over. A man in a long gown and a team of guards came up and shouted:

"Pillar? I'm afraid it's a disaster for the country, right!"

When Yang Duanhe and others saw the people, they quickly bowed their hands and said:

"See Tai Fu!"

Shen Bing immediately guessed the identity of this person: the teacher of Prince Fusu, Chun Yuyue.

It is said that although Confucius did not become a high official, but the Confucian children are very good.

For example, Wei's prime minister called Shicheng, and Chunyu Yue in front of him are all great scholars.

Shen Bing didn't know where to offend him. The more Chunyu came up, he gave Shen Bing a cold eye and asked:

"Are you worker Shen Bing?"

Shen Bing replied:

"It's the subordinate!"

Chun Yuyue asked again:

"How can you come up with a great strategy for water attacks?"

Yang Duan and Qi Dao:

"Master, what's wrong with this plan?"

"This is..."

Yang Duanhe wanted to say that this was made by the king himself.

But it is inconvenient to think about it, because it might reveal the whereabouts of the king.

Chun Yuyue only gave a cold "hum" and said angrily:

"The land around the beam is a plain. If the river is attacked, how can it not kill and wound the people?"

"Sure enough, even if the State of Qin wins the Central Plains, where are its benefits and morality?"

"If righteousness and gain are lost, how can we settle the world?"

Then Shen Bing understood that this guy came for "the world under heaven" and seemed to disapprove of flooding the beams.
