His name was Zheng Guo and he was a water engineer, and he was the one who was sent by Wang Jian to flood the beams. Who else could he be but the one who built the Zheng Guo Canal?
When Zheng Guo heard Shen Bing's name, his eyes widened like Shen Bing's:
"Could the stingy man... be the same Shen Bing who built the waterwheel and overturned it?"
Yang Duanhe smiled and replied:
"Who else could it be if he wasn't him?"
"If you help the plumbers with a stingy husband, you won't humiliate the plumbers!"
Zheng Guo quickly raised his hands and said:
"Of course."
"I've heard about the name of the stingy husband for a long time, but today I saw that he was indeed a talented man."
Shen Bing quickly returned the gift:
"Don't dare."
This Zheng Guo is one of the rare outstanding people in this era.
If you don't know, you would think that Zheng Guo just built a canal... Couldn't it be done with manpower and time?
But if you really understood it, you wouldn't think so.
However, areas located in inland areas with high evaporation often have salinization problems because the salt in the evaporated water is left behind.
Although fresh water contains very little salt, it cannot withstand the accumulation of salt over time... Over time, the land will become salinized and it will be impossible to grow crops.
Guanzhong of the Qin State (today's Jingyang area of Shaanxi Province) is such an area. The salinization of the area is very serious, and even the nearby lake water is salty.
This problem is difficult to solve even in modern times, but who would have thought that the Qin State, more than 2,000 years ago, had this water engineer named Zheng Guo solve it.
There is a river in Guanzhong called Jingshui. The characteristic of this river is that it contains a lot of mud and sand.
It originally ran north-south and merged into the Wei River, which had no effect on the large saline-alkali land in the middle.
As a result, Zheng Guo had a stroke of genius... he built a canal to divert the Jingshui River into an east-west direction and lead it to Luoshui River. During this period, he also introduced several tributaries into the Zheng Guo Canal to enrich the water supply.
This is nothing in the first place. It can be done with a lot of people and a lot of time, but it has no technical content.
The point is...
The amount of water is controlled just enough to overflow the Zhengguo Canal during the flooding period, causing the muddy and sandy Jingshui to flow to the saline-alkali land below, and it does so regularly every year.
As a result, the surface of the saline-alkali land was covered with a layer of fertile sand... From then on, the saline-alkali land became fertile farmland.
The historical record of this is:
"When the canals were formed, water was injected to fill the silt, and more than 40,000 hectares of land (1.1 million acres in today's dollars) were irrigated and irrigated. Each mu was harvested for one minute (100 kilograms in today's dollars). Guanzhong became a fertile field. In the years without bad luck, the Qin Dynasty Wealthy and strong, he joined the feudal lords and was named 'Zheng Guoqu'."
To put it into detail, Qin State harvested an additional 110 million kilograms of grain every year, so Qin State had enough grain to destroy the six countries.
None of this matters.
The important thing is...this method is like traveling through time, okay?
Only modern people know that the Nile River in Egypt floods every year, bringing fertile land to the desert areas on both sides.
What’s more, during the Qin Dynasty, which was more than 2,000 years old, before Egypt or the Nile River was known to exist, someone built a Zheng Guo Canal that could flood the saline-alkali land regularly every year?!
Moreover, the Nile River is naturally formed, and it is said that it 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 can it be done without accurate measuring tools?
Is it just relying 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 wouldn't understand what he said... Did this embarrass the time traveler?
After Zheng Guo nodded in greeting to Shen Bing, he cupped his fists at Yang Duanhe and said:
"General, this water attack strategy... I'm afraid it won't be that easy."
Yang Duanhe couldn't help but wonder:
"Why?"
Zheng Guo ordered his people to take the map, put it on a stone platform, pointed at the map and said:
"The Honggou water system near Daliang was built over several generations and is now more than a hundred years old."
"Now the waterway is too silted up. It should have been cut off long ago to dig out the silt and remove the blockage."
"It's a pity that all the countries have been unable to cope with the war for many years, so although the gap leads to the Yellow River, the water flow is small!"
"If we open the river embankments... I'm afraid the water will not flow into the Bian River as we wish."
"Perhaps even though it was poured into the Bian River, the water was not powerful enough to overwhelm Daliang Jiancheng."
Yang Duanhe couldn't help being shocked and asked:
"How did the hydraulic engineer know that the river mouth was blocked?"
No wonder Yang Duanhe asked this question. They had not yet reached the mouth of the Bianhe River, and Zheng Guo had only measured the water volume of the Yellow River.
Zheng Guo replied:
"There is a folk song in the Wei State: 'The ditch is blocked by mud, the water in the half canal is full of water, the river is surging, and the corn is difficult to fertilize.'!"
"This is a water matter. The general has been busy fighting all year round, so it is normal that he has not heard about it."
Yang Duan said "Oh" and then turned his attention to Shen Bing.
Shen Bing understood.
The root cause is the high sediment content of the Yellow River.
Because of the high sand content, ditches leading from the Yellow River, including Bianshui River, will have river mud accumulation.
Therefore, if water breaks through the embankment and attacks Daliang, the river water is likely to be blocked by mud and spread around the river mouth instead of pouring into the Bian River and rushing towards Daliang City.
Shen Bing couldn't help but frown, it seemed like 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 couldn't help but asked in confusion:
"This plan...could it be decided by the stingy husband?"
Shen Bing cupped his hands and replied:
"It's my subordinate who made the plumber laugh!"
Zheng Guo looked at Shen Bing and nodded slightly, sighing:
"The next generation is to be feared, the next generation is to be feared!"
"The Chessman is not only an excellent carpenter, but also a talented general. He is truly the pillar of our Great Qin..."
Before he finished speaking, he was interrupted. A man from behind wearing a long gown and a group of personal guards came up and shouted:
"Dongliang? I'm afraid it will bring disaster to the country, right?"
As soon as Yang Duanhe and others saw the person, they quickly bowed their hands and said:
"See Taifu!"
Shen Bing immediately guessed the identity of this person: Prince Fusu's teacher, Chunyu Yue.
It is said that although Confucius did not become a high official, he was a Confucian disciple who was very outstanding.
For example, the prime minister of Wei State named Shicheng and Chunyu Yue in front of him were both great Confucians.
Shen Bing didn't know where he offended him. When Chunyu Yue came up, he gave Shen Bing a cold look and asked:
"Are you Shen Bing, a hardworking man?"
Shen Bing replied:
"It's my subordinate!"
Chunyu Yue asked again:
"How can you come up with a plan to attack the beam with water?"
Yang Duan and Qidao:
"Master, what's wrong with this plan?"
"This is..."
Yang Duanhe wanted to say that this was approved by the king himself.
But when I thought about it, it was inconvenient to say it, because if I said so, it might expose the whereabouts of the king.
Chunyu Yue just gave a cold "hum" and said angrily:
"There are plains all around Daliang. If we cut through the river to attack it, how can we avoid killing and injuring thousands of people?"
"Sure enough, even if the Qin State takes over the Central Plains, what are the benefits and where is the morality?"
"If justice and gain are both lost, how can we bring peace to the world?"
Then Shen Bing understood that this guy was here for "all the people in the world" and seemed to disapprove of flooding the beams.
