Zheng Guo, the most famous hydraulic engineer in South Korea, is responsible for water conservancy projects and flood control throughout the country. At that time, he had already participated in the control of Yingze floods, the renovation of Honggou Canal and other water conservancy projects.

He has a huge reputation in related fields. He is a famous (outstanding) water conservancy expert and technical engineer. He once served as a hydraulic engineer (official name) in charge of water conservancy affairs in South Korea.

Now he has been ordered to go to Qin to lobby, and it is recommended to divert the Jingshui River from the east to the Beiluo River as a canal. On the surface, it can develop Qin's agriculture, but the real purpose is to make him a spy, deplete Qin's strength, and prevent the invasion of Korea.

Zheng Guo had a very good psychological quality, and his face remained calm despite being attacked by swords and axes. Even though he was abducted by Lu Buwei overnight, he was summoned to Xianyang Palace before he woke up.

In front of the officials of Qin State, Zheng Guo was naturally decent, neither humble nor overbearing. "I, my minister Zheng Guo, paid homage to the King of Qin and met all the princes."

Zhao Zheng looked around and saw that he looked ordinary at this time and could not tell that he was a sneaky person at all.

"Lu Xiangyan said that Zheng Shuigong can help the Qin State to build water conservancy and benefit agriculture and mulberry."

South Korea borders Qin, but South Korea is the first pass for Qin to exit from the east. If Qin starts a war to destroy the country, South Korea will be the first to bear the brunt, because South Korea has no cities to secede from.

This is the plan to weaken Qin, and the meaning of Zheng Guo’s presence here. Zheng Guo took a deep breath and said:

"Back to King Qin, this is the Jingshui River, and this is the Luoshui River.

If a large irrigation canal is dug out between Jingshui and Luoshui, the eight hundred miles of Qinchuan will become a fertile land."

Zheng Guo will cleverly make use of the terrain characteristics of the Guanzhong Plain, which is high in the northwest and low in the southeast, so that the canal water can flow for irrigation.

At the same time, a unique "cross-cutting" technology will be used to block the water flow of Qingyu River and Eoyu River, allowing them to flow into the canal, saving time and effort and allowing sufficient water in the canal.

In fact, even if it is "completed", the national canal project will be enough to help Qin's agriculture and mulberry production. However, even if one hundred thousand people are mobilized for this project, it will take eight to five years at least.

This level of mobilization is enough to exhaust the Qin people's financial resources and war potential, so as to "tire Qin" to achieve the purpose of defending South Korea.

Zhao Zheng still knows Shaanxi very well. Guanzhong is not only the hinterland of the Qin State, but also the granary.

Developing Guanzhong's water conservancy farmland and increasing Qin's grain production will also enhance Qin's war potential.

To go east and unify the six countries, isn't the prerequisite for strong soldiers and horses? This requires people to have food, and where will the population and food come from, of course it is the development of water conservancy.

Zhao Zheng surrounded the audience, and as expected, all the officials were aroused by Zheng Guo's words. After all, farming is engraved in the DNA of this nation.

However, as the Qin of tigers and wolves, Qin can be said to be a cultural desert, relatively barbaric (military system), and all kinds of talents lag behind the remaining six countries.

The same is true for water conservancy technology. It's not that the people of Lao Qin don't want to develop water conservancy on a large scale, but that this thing cannot be mastered without professional research.

For a time, Zheng Guo became famous, and hundreds of officials rushed to ask for advice.

Seeing this scene, Lu Buwei couldn't help but narrowed his eyes, fight, fight, what a surprise there is now, how frightening there will be in the future.

Therefore, power can really change a person. Without the threat of Zhao Zheng's rise, Lu Buwei would be the most loyal prime minister to Qin.

Because only when the Qin State is strong, can the Lu family's cronies be able to survive the Lu family's Spring and Autumn Period.

But now, in order to attack Zhao Zheng, Lu Buwei did not hesitate to harm Qin's national power.

It is not that there are no sober people in the court. This Zheng Guo came inexplicably and he is a Korean. Could it be a deception?

Some people even raised objections: Is it really effective? Don’t invest a lot of money at that time. In the end, it will be all in vain and a huge waste of national power.

However, Zheng Guo came prepared. His professional knowledge was enough to answer everything, and his historical achievements had long been confirmed. He was a master of water conservancy.

"River sediment contains very rich organic matter, (microorganisms) organic minerals (trace elements), which can be used to irrigate fields and turn wasteland into fertile farmland."

Zheng Guo planned to adapt to local conditions, divert water with high sediment content from the Jing River, and improve the (saline) alkaline land in Guanzhong through irrigation, and achieve the goal of high yields and harvests.

"Using water fillings to control the water, more than 40,000 hectares of land were irrigated and fertilized, and every acre was harvested. It was already a fertile field in the middle of Guanzhong, and there were no bad years. Qin became rich and powerful and merged with the princes!"

Zhao Zheng has a clear understanding of past lives. In history, it was the existence of Zheng Guo Canal that made the Qinchuan area in Guanzhong eight hundred miles one of the most important granaries in ancient China.

After many measurements and inspections, archaeologists found that the irrigated farmland area of ​​Zhengguo Canal reached 1.18 million acres, and some said it was 2.8 million acres. However, whether it was 1.18 million acres or 2.8 million acres, the irrigated area was more than 10,000 acres. This is

It is an undisputed fact that it effectively solved the most important irrigation problem in agriculture in Qin at that time.

Moreover, the Zhengguo Canal adopted the method of "mud water irrigation". A large amount of Yellow River water irrigated acres of land, which greatly reduced the salinity of the land in the Guanzhong area and improved the water and soil of the saline-alkali land. To a certain extent, it increased the Qin's

The country's fertile farmland area. The emergence of the Zhengguo Canal greatly improved the agricultural development of the Guanzhong area, turning Guanzhong into a fertile granary, thus laying the economic foundation for Qin Shihuang to unify the six countries.

This can be seen from the struggle for hegemony in the Sui and Tang Dynasties. The Li family, who started in Guanzhong, is the most convincing proof.

This is of great significance to the Qin State, which is currently expanding.

The stable development of agriculture means a steady increase in the number of people that can be supported, which is tantamount to providing a steady supply of soldiers for the Qin army.

In addition, for war, military rations are also a crucial factor.

According to historical records, the millions of acres of farmland irrigated by the Zheng Guo Canal provided enough military food for the Qin State's 600,000 troops for several years.

In this way, Dujiangyan in central Sichuan and Zhengguo Canal in Guanzhong are like the two wings of Qin. They not only provide Qin with stable and reliable supply to the rear of the war, but also become a powerful boost to Qin to a certain extent.

Therefore, the Zheng Guo Canal was revised by the Qin State. Zhao Zheng showed his courage and Jinkou made a decision, "I wonder how much budget this requires based on what Zheng and everyone sees?"

Budget?

Seeing that not only Zheng Guo was puzzled, but most of the officials were also confused, Zhao Zheng said bluntly: "This is the financial, material and manpower needed for the Jingluo General Project."

The answer given by Zheng Guo happened to hit Qin Guo's weakness.

One hundred thousand civilians, ten years to dig through!

Upon hearing this, Lu Buwei's eyes suddenly lit up.

Zhao Zheng's eyes lit up.

It’s not that no big shot in the DPRK saw that Zheng Guo’s purpose was impure. However, after the Jingluo project was opened to water, even if it was not as exaggerated as Zheng Guo said it would benefit eight hundred miles of Qinchuan, it was just basic paddy fields. Guanzhong also

Will be used as food.

It’s only ten years, Qin can afford to wait.
