The feast of Qin's annexation of six countries seems to be smooth sailing, but it is actually the result of hundreds of years of national strength accumulation. The sudden outbreak of Ying Zheng was actually due to the great contribution of Korean spies. When Ying Zheng first came to power, his first goal was the fragile South Korea around him. In 246 BC, in a desperate situation, the King of Han and Huan came up with a strategy of "eliminating Qin". He sent Zheng Guo, a famous water conservancy engineer, to spy on Qin Wei to lobby Qin State to dig large irrigation canals in Shuijing and Luoshui. On the surface, Qin's agriculture can be developed, and the real purpose is to exhaust Qin's manpower and material resources to delay Qin's March into the Central Plains.
Ying Zheng, who just came to power, wanted to expand his national strength. When he heard that there was such a suggestion, he naturally supported it very much. So he immediately gathered all his strength to pour out the country, and Zheng Guoren was appointed as the chief engineer to preside over the construction project. In the process of construction, Zheng's identity as an underground worker was exposed, and Ying Zheng felt that he had been played and immediately wanted to dismember Zheng. He said, "I became a minister, but it was also beneficial to Qin." I lived for Yan Hansheng for several years, but I worked for Qin Jian all my life. "This is true. Han Huan-wang's genius strategy is like persuading a person to take a martial arts class when he is beaten by a rogue, and then coming back to kill himself when he becomes a peerless master. Ying Zheng is a clever man. He knew that Qin's hydraulic technology was backward, and Zheng was just the talent he needed. So the project went on. More than ten years later, the canal, which is more than 300 miles long, was completed, and it was named Zheng Guoqu.
After the completion of Zheng Guoqu, the national strength of Qin was greatly enhanced. "Historical Records" and "Hanshu" both said: "When the canal is drained, it is filled with water (silt), and more than 40,000 hectares of brine are filled, and the harvest is one mu. Therefore, Guanzhong is fertile, and there is no bad year. Qin Fuqiang, who died as a vassal, was named. " At that time, the average yield of other vassal States was one and a half stone per mu, and that of Guanzhong area was more than four times higher. With the increase of grain output, the population will also increase. At that time, many people were power. King Han Huan nailed the last nail to the coffin of himself and other six countries, and the first dish for Ying Zheng to destroy the six countries was South Korea. In 230 BC, Qin Jun captured Xinzheng, the capital of South Korea, and Han An, the last king of South Korea, surrendered. The authorities tried their best to enhance the national strength of the enemy country, and the Zheng espionage case can be regarded as a rare failure case in the history of world espionage.
Multi-faceted spy Zigong
During the Spring and Autumn Period, it was popular to talk big and fool people. The lobbyist is actually a special political spy who affects the political situation of other countries, and Zi Gong is an expert in this field. When I first arrived in Qi, Tian often said that it was meaningless to attack Lu, because Lu was difficult to attack. Tian Chang asked Lu, how can it be difficult to fight a bird country that is not much bigger than mung beans? Zi Gong said that the land of Lu was small, the monarch was stupid and the ministers were hypocritical, so it was best not to attack. Attacking Wu is not as meaningful as attacking Lu. You see, Wu's national strength is strong, its soldiers are brave, and its weapons are excellent. It is very meaningful to attack it easily.
When Tian Chang heard this, he couldn't wait to inform the mental hospital directly to pull people. Zi Gong quickly explained: If suffering is included, then attack a powerful country. If suffering is outside, attack the weak country. Now, including your fears, there are countless political enemies in North Korea. In order to weaken the political opponents, we should attack Wu. At that time, Qi will certainly suffer heavy losses and the war will drag on for a long time. All capable ministers will be stationed at the front line to lead the troops to fight. The country is extremely empty and no one helps the monarch. Isn't it easy for you to launch a coup at this time?
After listening to Zi Gong's words, Tian Chang repeatedly praised: Youxi, what a good idea! But I have sent troops to Lu and attacked Wu again. Will it arouse the suspicion of ministers? Zi Gong said it was easy. You just stay where you are. I'll trick the prince into saving Rufaqi, and then you can send the Qi army to fight.
Then, Zi Gong ran to the king of Wu and said, Now is a good opportunity for the king of Wu to destroy Lu! If you save Lu, you can get a good reputation for helping the poor, and defeating Qi can also threaten the powerful Jin, but there are too many benefits. The king of Wu agreed well, but I had a fight with Gou Jian, the king of Yue, for fear that he would send troops to sow discord while I was unprepared. Why didn't I kill him first? Zi Gong said no problem. I'll persuade the king of Yue to send troops to cut Qi with you, so that he has no right even if he wants to make a mess. The prince of Wu was very happy, so he asked Zi Gong to find Yue at once.
Zi Gong rushed to the King of Yue and said, Everyone knows that you are going to attack Wu for revenge, and the King of Wu also intends to destroy you first, thanks to my brothers. Let me give you a good idea. Of course, you can please him by sending troops to cut Qi with him. If the prince of Wu is defeated by the state of Qi, it will be your blessing. If you win, you will inevitably threaten the state of Jin with troops. When the time comes, I can go to the north to see the king of Jin, and let him send troops to attack Wu with you, which will inevitably weaken Wu. When all his elite soldiers are transferred to fight against Qi, and the troops are besieged by Jin, you can take advantage of its emptiness and destroy Wu in one fell swoop. The king of Yue was overjoyed. He sent 5,000 troops to help the King of Wu cut Qi, and also presented many gold, silver and jewels. Fu Cha saw very happy, no longer have trouble back at home, so he sent troops to cut qi.
The last stop of Dagong Zigong is the state of Jin. He told the King of Jin that Qi was going to fight with Wu, and if Wu was defeated, Qi would take the opportunity to disturb Jin. If you win, you will also threaten the state of Jin with the winning teacher. The king of Jin hurriedly asked Zi Gong how to deal with it. Zi Gong said that it is good to train the army to be on strict alert.
The following things are basically developed according to Zigong's plan. The prince of Wu mobilized his army to cut Qi, and the two armies fought in Aileen. After Wu Jun defeated the Qi army, he really bullied the State of Jin with the victorious army. Because the state of Jin was well prepared, in the end, the state of Wu was only the overlord in name only. When Gou Jian, the King of Yue, heard that the King of Wu was going to war, he immediately led troops to attack the State of Wu. The prince of Wu led troops to rescue and was defeated one after another. A few years later, Wu perished.
In fact, Su Qin is also a spy of Yan. Taishi Gong didn't see it.
Su Qin (? -284 years ago), during the Warring States Period, Luo Yang was born in Li Xuan, a native of the Eastern Zhou Dynasty. Yan Zhaowang ordered him to enter the State of Qi to engage in anti-espionage activities, which made the State of Qi tired of foreign wars, in order to attack the State of Qi and avenge the State of Yan. Wang Qimin was at the end of his term. King Qin Zhao made an appointment with King Qi Min, also known as the Eastern and Western emperors. He persuaded the king of Qi to cancel the title of the emperor, and attacked Qin with Zhao Li in about five countries, which was sealed by Zhao. The five countries jointly attacked Qin, forcing Qin to abolish the emperor and return part of Wei and Zhao's land. Then, Qi took the opportunity to attack and wiped out the Song Dynasty. Hou Yan attacked Le Yi and the five countries on a large scale, only to find that the anti-espionage activities were exposed and were destroyed by cars.
