As mentioned earlier, after the state of Cai signed an alliance with the state of Chu, the marquis of Cai Zhao came up with the idea of moving the capital near the state of Wu to seek the protection of the state of Wu. Cai Zhaohou secretly sent his nephew Gongsun Pian to Wu to express his willingness to move the capital to Fucha, but Fucha was preparing to attack Yue at that time and had no time to look north; However, he promised to help Cai Guo complete the relocation of the capital immediately after the invasion of Yue.

Since this matter was done behind the back of the doctor and the Chinese people, Cai Zhaohou did not dare to imagine what kind of danger he would face once the news was leaked; But thanks to the assurance of Wu Guoren, self-confidence returned to his side.

Cai Zhaohou began to test the attitude of the doctors in various ways and inculcate pro-Wu ideology, but the reaction of the doctors made him very worried: most people were reluctant to leave their homeland and become neighbors with a petty tyrant.

Cai Zhaohou couldn't sit still. He didn't dare to arouse the anger of the public, so he came up with the idea of retreating. Cai Zhaohou again sent Gongsun Pian to Wu to report the situation, saying that he could not convince the doctors in a short time, and asked for a postponement of the operation.

Fu Cha was furious, and he thought that Cai Zhaohou had reversed his word and prevaricated himself under the pretext of the doctor's countryman, which was unforgivable "blasphemy and madness".

But the husband did not directly reprimand Cai Zhaohou, but said sternly: "Doctor Cai Zhi is not loyal to the monarch and does not sympathize with the society, but is an outright traitor, and he will be ruthlessly exterminated!" Wu and Cai have an alliance, and the widow cannot sit idly by and watch Cai Guosheji be bullied by the Chu State and destroyed by the doctor; The widow will definitely take on the heavy responsibility of saving Cai Guo from danger! The matter of moving the capital cannot be changed, and the widows will send heavy troops to protect Cai Hou and fight the rebels to ensure the smooth completion of the capital relocation plan. After that, he ordered the doctor to come up with a plan. The two stayed up for two days and two nights, and finally completed the task. The plan was presented to the husband and approved immediately.

After Cai Zhaohou got the news, he had to make up his mind and prepare a dead horse as a live horse doctor.

Gongsun Pian's two missions were carried out in secret, so the doctors and the people were still kept in the dark.

In the spring of the second year of Lu Aigong. In order to hide people's eyes, Cai Zhaohou specially sent Gongzi Si to the Gusu Dynasty to meet his husband with great fanfare to congratulate Wu on his complete victory in the war against Vietnam.

In the autumn of that year, Wu Wangfu sent a doctor to Cai to pay a "return visit", and Cai Zhao ordered his son to go out of the city to meet the Wu delegation. Seeing the large number of troops brought by the emperor, Gongzi Si couldn't help but doubt in his heart: "Although the pomp and circumstance of the envoys of the Wu State has always been very large, this time it will not bring an army that can destroy a small country!" ”

Fu Yong saw the doubts, so he explained: "Chen Hou is not sensitive, I will go to Chen Guo to greet Chen Hou after I leave Cai Guo." Childe, please rest assured, they will not enter the Cai Kingdom. ”

Only then did Gongzi Si put his mind at ease. He led the way in front and led the Wu Guoyi guard into the city, and the Xuan chariot of the vent and the prince marched side by side. The unexpected happened suddenly: he jumped into Gongzisi's car and hijacked him, and the fancy ministers in the honor guard suddenly ripped off their coats, revealing the leather armor inside, drew out the hidden short weapons, and subdued the surrounding Cai soldiers. The people of Wu quickly occupied the city gate, put a large army into the city, and Chu Yong led the team to break into the palace and put the doctors of Cai Guo in one pot.

When the time for the showdown came, Cai Zhaohou stood up and announced the plan to move the capital to the ministers. Although the doctors were under the sword guards, there were still some brave and unyielding men who waved their fists in anger and shouted loudly, claiming that they would rather die than leave the capital.

He had a list of opponents (the list was given to the people of Wu by Cai Zhaohou); On the spot, he killed the two two people with the most emotion and the most opposition. Cai Zhaohou was afraid that he would not be able to control his murderous intentions, so he hurriedly ran over to stop him and begged him not to kill again.

After Fu Yong stopped, Cai Zhaohou asked him and the sergeants to withdraw from the main hall and give them some free space. After Wu Guoren left, the doctors' emotions eased slightly, and they gradually recognized the situation and knew that the situation was irreparable, so they had to reluctantly accept the reality.

The monarch and his ministers began to discuss the plan for moving the capital, and the meeting began in the morning and lasted until the third day of the month.

Everyone finally reached an agreement, and Cai Zhaohou had just breathed a sigh of relief, when the doctor Cai Tong suddenly said: "Cai's defense is so weak that Wu Shi occupied the palace without killing anyone, and Sheji almost perished. How should this crime be prosecuted? ”

The other ministers also waved their fists and demanded that those responsible be punished - the crime was so serious that even Cai Zhaohou could not save the life of Gongzi Si (although he was not involved in the conspiracy). So the innocent old man was put to death as a scapegoat.

Early the next morning, Chu Yong left the capital with the eldest son of the crown prince and the doctors, and the Marquis of Cai Zhao immediately issued a relocation order, which immediately caused a huge commotion. The people of the country were excited, and they scolded Cai Zhaohou and the doctors, scolding them for bringing disaster to the country and the people; Some began to gather crowds to make trouble, attacking officials and civilians, looting and setting fires. But the riots were soon suppressed.

A few days later, the Cai people helped the old and the young to leave the capital, and migrated to Zhoulaicheng (now Fengtai, Anhui) as if fleeing the famine under the "escort (or surveillance)" of the Wu people.

As mentioned earlier, the state was originally the object of fierce competition between Wu and Chu, and before its demise, it was the protectorate of Chu. In the thirteenth year of the reign of Emperor Lu Zhao (BC529), King Yi of Wu took advantage of the opportunity of the prince of Chu to abandon his illness and launch a coup d'état and overthrow the rule of King Ling of Chu to destroy the state and divide it into a county of Wu.

The annexation incident has become an eternal pain in the chest of the people of Chu; Now the Cai people are treacherous and resolutely betray the Chu State, and as a result, the move of the capital has caused the double hatred of the Chu people.

The people of Chu immediately released cruel words: "Don't think that you will be fine if you come to the state, my Great Chu will never let go of the country that has betrayed the alliance, and the Tang State is your best example!" Just wait for the moment when the Great Chu Lion Soldiers will come down to the city! ”

The threat was not just rhetoric, and the Chu people soon put the destruction of Cai on the agenda: the generals began to train their troops on a large scale, conduct military drills, and build siege engines.

In the new capital, the Chinese people's complaints about Cai Zhaohou have not stopped. It turned out that many Chinese people owned land and property near the old capital, and after moving the capital, their property was basically unkept; The new settlements were more populated and less land, and although Cai Zhaohou redistributed land to the people, the property they lost was far greater than what they gained. The doctors were in a similar situation. Gradually, the things that Cai Zhaohou did to hide from the doctors and countrymen also surfaced one after another, some of which were true, and some of which were made up by people for various purposes. When Cai Guoren woke up from a dream, they all felt that they had been fooled, and Gongzi Si and the pro-party of the doctors who were killed by Wu Guoren could not accept the reality. As a result, a powerful anti-Cai Zhaohou force emerged in the Cai State.
