Daqin Engineering Corps

"Of course."

"I've heard about the name of a miser for a long time, but today I saw him and he is indeed a talent."

Shen Bing hurriedly returned the gift:

"Don't dare."

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

If you don't know it, you think that Zheng Guo just built a canal... Wouldn't it be enough to use manpower and time to pile it up?

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

However, inland areas with high evaporation often have problems with salinization. The reason is that the salt in the water evaporates and remains behind.

Although fresh water has very little salt, it cannot withstand the accumulation of time... Over time, the land will become salinized and cannot grow crops.

Guanzhong of the State of Qin (now the 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 in modern times, but who would have thought that the state of Qin, more than 2000 years ago, would be solved by the water engineer named Zheng State in front of him.

There is a river in Guanzhong called Jingshui, which is characterized by a large amount of mud and sand.

It originally ran north-south and then merged into the Weishui River, which has no effect on the large saline-alkali land in the middle.

As a result, Zheng Guolai came up with a magic pen...a canal was built to divert the Jing River from east to west to Luoshui, and several tributaries were introduced into the Zheng Guo Canal to enrich the water volume.

This is nothing at all, it can be done with a lot of people and a lot of time, and there is no technical content.

The point is...

Its water volume is just controlled to overflow the Zhengguo Canal during the flooding period, causing the muddy and sandy Jingshui to flow to the saline-alkali land below, and this happens regularly every year.

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

The records of the history record are as follows:

"Cultures are formed, filled with silted water, irrigated more than 110 hectares of brine land (100 million mu today), and harvested every mu for one bell ([-] kilograms today), so Guanzhong is a fertile field, and there is no evil year. Wealthy and powerful, he died and joined the feudal lords, and was called 'Zhengguo Qu' by order."

Calculated in detail, Qin State received 1000 million kilograms of grain extra every year because of this, so Qin State had enough grain to destroy the six countries.

None of this matters.

The important thing is... this method is simply from time travel, okay?

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

What's more, in the Qin Dynasty more than 2000 years ago, the Qin Dynasty didn't know there was Egypt or the Nile River...someone built a Zhengguo Canal that can regularly flood the saline-alkali land every year? !

Moreover, the Nile River is naturally formed, 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 can it be done without accurate measurement tools?

Is it just relying on the iron ruler in Zheng Guo's hand?

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

After Zheng Guochao Shen Bing nodded, he clasped his fists at Yang Duanhe and said:

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

Yang Duanhe couldn't help but wonder:

"Why?"

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

"The Honggou water system near Daliang has been built for several generations, and it has been more than a hundred years."

"Now the waterway is so silted up that it should have been cut off long ago to dig out the silt."

"It's a pity that the countries have been fighting for years and are unable to look forward to it. Therefore, although the gap runs through the Yellow River, the water potential is small!"

"If we decide to open the embankment... I'm afraid the river will not be poured into the Bian River as we wish."

"Or even though it is poured into the Bian River, the water is not strong enough to destroy Daliang Jiancheng."

Yang Duanhe couldn't help being shocked and asked:

"How did the water engineer know that the estuary was closed?"

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

Zheng Guo replied:

"There is a folk song in Wei: 'The gap is blocked by mud, the water in the half-canal, the river is surging, and the corn is hard to fat.'!"

"This is a matter of water. The general has been busy fighting all year round. It is normal that he has never heard of it."

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

Shen Bing understood.

The root cause is the large sediment content of the Yellow River.

Due to the high sediment content, the ditches leading from the Yellow River, including the Bian River, will have river mud accumulation.

Therefore, if the embankment breaks and the water attacks Daliang, the river water will probably spread to the surrounding area due to mud blocking the river mouth instead of pouring into the Bian River and rushing towards Daliang City.

Shen Bing couldn't help but frowned, 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 couldn't help but asked in doubt:

"This plan... Could it be that the stingy man made it?"

Shen Bing cupped his hands and replied:

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

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

"The future generations are terrifying, the latter generations are terrifying!"

"The coward is not only good at carpentry, but also talented as a general. He is really the pillar of my great Qin..."

The voice was interrupted by someone, and a person in a long gown came up with a team of personal guards and shouted:

"Dongliang? I'm afraid it will be a disaster for the country!"

As soon as Yang Duanhe and others saw the person, they hurriedly bowed their hands and said:

"See Taifu!"

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

It is said that although Confucius did not become a high-ranking official, his disciples of Confucianism were very good.

For example, the Prime Minister of Wei State called Shicheng, and Chun Yuyue in front of him are all great Confucians.

Shen Bing didn't know where he offended him, so Chunyu gave Shen Bing a cold look when he came up, and asked:

"Are you a hard worker and a heavy soldier?"

Shen Bing replied:

"It's the subordinate!"

Chunyu Yue asked again:

"How can you come up with the strategy of attacking the beam with water?"

Yang Duan and Qi said:

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

"This is..."

Yang Duanhe wanted to say that the king personally agreed to this.

But it's inconvenient to say it after thinking about it, because it may expose the king's whereabouts.

Chunyu Yue just let out a cold "hum", and said angrily:

"The girder is surrounded by plains, if the river floods it and attacks it, how can it not kill or injure thousands of people?"

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

"If both righteousness and profit are lost, how can the world be safe?"

So Shen Bing understood that this guy came for "the common people in the world", and he seemed to disapprove of flooding the beams.

This……

Chapter 1 Thirty

Chunyu Yue was originally from Qi.

In the Warring States Period, the gaps between the countries in the Central Plains were not that deep, and some of them even had the same ancestors if you look closely.

For example, Zhao Guo and Qin Guo, who beat their lives to death, are distant relatives, but their hatred has become more and more difficult to reconcile.

Hatred turns to hatred, people and literati and military generals are still running around in various countries, showing loyalty to this country today, and showing sincerity to another country tomorrow.

Although there is an element of chasing fame and fortune in this, it is still fundamentally different from being loyal to foreigners.

For example, Qin Kai, a famous general of Yan State, was a native of Lu State who was held hostage in Donghu, and he was deeply trusted by Donghu.

But he still chose to flee back to the Central Plains, and then led the Yan army to fight Donghu to expand the territory.

Therefore, it is common for Chunyu Yue of the state of Qi to serve as the tutor of the state of Qin, and for the state of Zheng of South Korea to be a hydraulic engineer in the state of Qin.

This Chunyu Yue had just completed his mission as an envoy to the State of Qi...

During this period of time, Qin State attacked either Zhao State or Yan State, and then Wei State.

These three countries are all on the border with Qi State, and the same is true for the Chu State that will be fought in the future.

If Qi Guo has a little bit of strategic awareness, he would know that after cleaning up these countries, it will be his turn next.

So it is entirely possible to send troops for reinforcements.

So I have to send someone to fool you...

But who can be sent to gain its trust?

Ying Zheng thought about it, and finally chose Chun Yuyue.

Yingzheng's move is a bit puzzling, because Chunyuyue is a great Confucian, and he is known for his straight and upright personality, so it seems a bit inappropriate to send him to do the job of fooling people.

But in fact, this is a good move by Yingzheng:

It is precisely because of Chun Yuyue's "straight and upright nature" that no one believes that he will lie, so it is easier to be fooled...

The difficult thing is how to get Chunyu to fool people!

It is almost impossible to persuade Chunyu Yue to take the initiative to do this kind of thing. If it is possible, it would not be called "straight, staunch and upright".

So Ying Zheng thought of a way: to fool Chunyu Yue first.

And it didn't seem difficult to fool Chunyu Yue.

Prince Taifu!

Ying Zheng used the excuse of looking at Fu Su as an excuse to get in touch with Chun Yuyue, and then sighed a few words from time to time:

"Hey, the country that I don't want to dispute the most is the country of Qi."

"The country of Qi is a land of blessings. It is said that the fairy mountain has appeared in the country of Qi many times, and many people of Qi have seen it."

"Such a place favored by gods, how dare the widows dare to attack it so easily?"

"It is because all the six countries can be destroyed, but this Qi country cannot."

"But why..."

Speaking of which, Ying Zheng sighed heavily again, and continued thoughtfully:

"However, if the few people have intentions, Qi Guo may not have intentions!"

"If Qi State takes advantage of the dispute between the widow and other countries to attack Qin, or sends troops to reinforce the enemy's country... the widow will have to send troops to Qi."
