The other is the Qin State where Shang Yang reformed. It was just a small person who had let the Zhou emperor go. After giving the fief, he was never seen by other vassal states. He has always considered it a barbarian in remote areas.

In Spring and Autumn Warring States Period events, rituals and music were broken, and the vassal states directly fought against each other. In 355 BC, two vassal states began reforms almost at the same time for their own strength.

One is the Korean after the three companies split into , and it is also the weakest among the three companies. After Han Zhaohou began to reform, other vassal states did not bully for fifteen years. The other is . Shang Yang's reform . The Qin State was just a small person who gave . The emperor of Zhou . After giving the fief, he was never seen by other vassal states. He has always considered it a barbarian in remote areas. After Qin Xiaogong ascended the throne, in order to change the status quo, under the result of Shang Yang's reform, the powerful Wei Kingdom ceded a large area of ​​land for the first time under the influence of Shang Yang's reforms.

Although both countries are strong due to reform, the two sides have great differences in reform in essence.

The important thing in South Korea's reform was "art", which required people to be particularly important. At that time, Han Zhaohou knew that people were good at responsibilities, which made South Korea feel prosperous and strong. When Han Zhaohou passed away, the successor ruler did not have the ability of Han Zhaohou, so he began to plummet again.

However, the Qin State's reforms focused on the system. At the legal level, many requirements that can make the country prosperous and strong are stipulated in the form of laws. Therefore, even if Shang Yang's end of is not good, Qin State maintained these legal contents, making Qin a target that other vassal states fear.

In 246 BC, 109 BC, the then King Han Henghui of South Korea was lying on the collapse because of this powerful nightmare of Qin. At this time, Qin State had already killed 400,000 surrendered Zhao troops in the battle with Zhao State in a big battle with the killing god Bai Qi . There is no existence in the world that can compete with Qin alone. Moreover, three years ago, the royal family of the Eastern Zhou Dynasty was also defeated by the Lu Buwei .

Losing the geographical barrier between the Eastern Zhou royal family between Qin and Han, allowing South Korea to directly face the powerful Qin State, and Qin State's advance eastward is the general trend. This made Han tremble when he thought of it, so King Han Henghui came up with a plan that could make Qin weak and ensure his own safety.

So I thought of my country, a master of water conservancy engineering, Zhengguo . King Han Henghui gave Zheng a major task, which was to go to Qin and try every means to let the other party start the construction of water conservancy projects, so that the other party could waste the people and money and consume the other party's treasury.

So Zheng State came to Qin State with this great mission and met the Ying Zheng , who had just become the king of Qin State, a boy who was only fourteen years old. This is not an ordinary boy, but a boy who is used to fighting in the court and is already quite calm and composed.

Suddenly saw another country coming to the office and asked his own country to overhaul the water conservancy. Ying Zheng was not surprised, but asked in detail why the canal was built. How to build a canal, when will it be completed, and how large the project volume is. Then after hearing Zheng State answer one by one, Qin State's court was surprised. If you really follow the advice of Zheng State to build the canal, it can be said that Qin State can use the power of the whole country at this time. This undoubtedly greatly slowed down the goal of Qin's generations advancing eastward, but it did have great help to Qin. Compared with the two, it is impossible to determine the pros and cons. However, Ying Zheng was extremely concerned about this matter, and then directly agreed to Zheng State's suggestion and began to take charge of the work.

In fact, the Dujiangyan built by Li Bing and his son made Qin deeply benefited. Therefore, Ying Zheng’s decision was not the only courage that the young man had. When Qin agreed to this matter, the news reached King Han Henghui's ears, which made him extremely happy, but he didn't know that the day the project ended was the time when the six Eastern countries perished.

Although Zheng State came with the purpose of weakening Qin State, there is indeed a grand blueprint to truly build a canal project that is beneficial to Qin State.

After a deep understanding of the situation in Qin State, he determined how to use Jinghe to eventually benefit the vast land and make countless farmers profit from it.Although Zheng State is not sure whether it can weaken Qin State, its career can make countless people profit, which is also the greatest affirmation of his work.

However, this project was only halfway through, and the real purpose of Zheng State coming to Qin was discovered by Ying Zheng. In a furious state, Ying Zheng decided to execute Zheng State, but Zheng State said that although his original purpose was indeed to drag down Qin State, the benefits of this canal to Qin State were also obvious. It just made South Korea survive for a few more years, but it has made contributions to Qin for eternity.

I have to say that there are inevitable reasons why Ying Zheng was able to unify the six countries. Although he is young, he has a long-term vision and a tolerance after careful consideration. So he decided to continue to support Zheng State in completing this project.

In 236 BC, Zhengguo Canal was completed. Let large areas of wasteland become fertile land for thousands of miles of fertile land. In order to commend Zheng State, Ying Zheng did not care about past grudges and named the canal the canal the Zheng State Canal.

At this time, the Qin State can be said to have countless fertile lands and many talents, and also have the energy to go east. The first target was South Korea, and then it captured the capital of South Korea and occupied the entire territory.

The subsequent story can be said to everyone know that Ying Zheng eventually unified the six kingdoms and became the first emperor in history. Zheng Guoqu has been improving over the next few thousand years, which has also benefited the Guanzhong region.
