Jiangguo is located on the north bank of the Huai River, west of Xixian County, and is a small country with the surname Win. After the rise of the Chu State, Jiang Guo joined the Southern Alliance, because Jiang State was only sixty or seventy miles away from the military city of Chu Xixian County, Jiang Bo obeyed the words of Chu State, and has always been loyal and trembling to serve the alliance leader. Later, Jiang Bo asked the king of Chu to marry, and the king of Chu Cheng married his sister Jiang Qixia to him. During the lifetime of King Chu Cheng, the two countries maintained close and friendly relations.

Later, King Chu Cheng was forced to commit suicide by the crown prince and merchants, and Jiang Mi blamed himself. She thinks that if she hadn't leaked the secret, her brother wouldn't have been killed. With great guilt and anger, she also hanged herself.

King Chu Mu tried his best to cover up his crimes, claiming that Jiang Mi died of grief because of the old king's violent death; Jiang Bo did not pursue this (nor did he dare), but just took Jiang Mi's coffin back to China. But both sides knew that the alliance between the two countries had broken down, and the end of the Jiang State was just around the corner.

Jiang Bo decided to take refuge in the Jin Kingdom, but he did not dare to contact the Jin people directly, so he hoped to achieve his goal through the hands of the Zheng Guoren.

It turned out that Jiang Bo had a younger sister, Ying, who married Zheng Wengong and gave birth to a son. This prince is okay in terms of conduct and ethics, but he likes to talk nonsense after drinking too much, and he is a Zheng Guo revivalist.

Zheng Wengong valued him very much and wanted to make him the crown prince, so he sent him to the state of Chu to make a pilgrimage. King Cheng of Chu ceremoniously entertained the future ruler of Zheng State, and Gongzi Shi did not expect that Chu State's wine was so strong, and he quickly got drunk.

Then he began to talk nonsense, as in the past, to the effect that as long as he was alive, he would strive to restore Zheng Guo's status as a great power and make Zheng Guo become the overlord of the Central Plains again; He could not tolerate the loss of the great exploits of Huan, Zhuang, and Li Gong in his own hands.

The people of Chu were angry and worried, and King Cheng of Chu could not publicly execute him, so he gave him chronic poison at the farewell banquet. As a result, the prince died on the way. Ying was greatly grieved, and she hated the people of Chu to death from then on.

Jiang Bo sent a secret envoy to Zheng Guo to find the Ying family; The Ying family took the secret envoy to see Zheng Mugong, and Zheng Mugong was very happy to make some achievements for strengthening the Huaxia Alliance, and immediately sent someone to lead the secret envoy to the Jin Kingdom.

However, there were disagreements among the people of the Jin Kingdom, and Zhao Yu felt that the Jiang State was small and far away, and it was not enough to expand its power to obtain it, and it would be difficult to protect it and lose money, so it was better to refuse.

Zhao Yuan's advice to Jin Xianggong was the same as Guan Zhong's advice to Qi Huan Gong back then.

However, the first Ju Heyang virgin father and others believed that although Jiang was small and far away, there were Zheng and Song, and the two countries could help Jiang resist the invasion of the Chu army, and could hold out until the Jin army arrived, and the two countries helping Jiang were equivalent to helping themselves; If the Jin State cannot accept the countries that take the initiative to take refuge, do not block the countries that take the initiative to leave; If Jiang Guo is rejected, Jin Guo will become a loner sooner or later.

But Zhao Yu thought that the idea of the two was too wishful thinking, and he said that Zheng and Song would never wade into this troubled water.

In order to balance the interests of the two factions, Xianggong of Jin adopted the opinion of Xian Jiju (Xianggong of Jin supported Zhao Yuan when the Qin army attacked Jin). As a result, Jin and Jiang reached an agreement: Jiang respected Jin as the leader of the alliance, and Jin provided security protection for the other party.

The Chu people discovered the betrayal of the Jiang people, which provided a pretext for the Chu state to attack the Jiang state. King Chu Mu decided to occupy Jiang before the Jin State intervened.

In the autumn of September, King Mu of Chu recruited an army in Xi County, and the Chu army surrounded Jiang Guo under the leadership of Zhu Gongzi Xi, Zheng and Song did as Zhao Yu expected, but they turned a blind eye to the danger of Jiang Guo. At this time, Jin Xianggong realized that the Jin Kingdom was so far away from the Jiang Kingdom, and it was simply an impossible task to rescue the Jiang Kingdom.

Jin Xianggong sent his servants to lead his division to invade Chu. The closest border town of Chu to the Jin State is Fangcheng. The first servant arrived on the outskirts of Fangcheng with a light army, but did not have enough strength to attack, so the Jin army had to set up camp far away to wait for reinforcements after making a few tentative attacks.

Duke Xiang of Jin sent an envoy to Wangcheng to report the situation to King Xiang of Zhou. King Xiang of Zhou ordered Wang Shuhuan to lead his army to attack Chu. Wang Shuhuan Gong joined forces with the Jin army and attacked the Fangcheng gate of the Chu State. Xi Gongzi Zhu did not dare to despise the Zhou and Jin coalition forces, and he gave up the siege of Jiang to solve the difficulties of Fangcheng. Seeing that the goal had been achieved, the coalition forces turned around and returned to the division.

The military and political officials of the Jin State calculated that the Jin army's unit cost three times that of the Qin Dynasty and five times that of the Chengpu Battle; This is just the consumption of going back and forth to Fangcheng Mountain, and it has not yet been calculated to Jiangguo. This result shocked the entire office, and Zhao Yuan's prophecy came true, and the Jin State could not afford to fight the war to rescue the Jiang State.

On the other hand, the people of Chu also calculated an account for the people of the Jin State, and the results obtained were basically consistent with the calculations of the Jin people, and their self-confidence returned to the side of the people of Chu. In this way, Jiang Guo will not be able to escape the doom of being destroyed.

In the summer of the fourth year of Duke Lu Wen (BC623), the Chu army once again besieged the Jiang State, and the Jin State could not be saved. It cannot but be said that the Jiang people resisted very tenaciously, but this was a war with a huge disparity in strength. Half a month later, the capital of Jiangguo was lost, and the Chu army attacked Jiangguo from all sides. Jiang Bo did not choose to escape, but led the soldiers to resist until death, and the Jiang Kingdom perished.

The one who felt the most sorrow about the ending was not the Jin people, but Qin Mugong. Because Jiang and Qin have the same surname and are also allies. Qin Mugong changed into simple clothes, lived in a simple room, removed the drum music, and detracted from his diet. The doctors advised him not to pay attention to this matter, as if the Qin State had suffered a great funeral.

Qin Mugong said: "The alliance perished, although the widow is powerless to save him, how dare he not mourn? The widow is also self-police! The poem says: 'If you maintain these two countries, you will not gain their government.' The four kingdoms of Weibi should study the degree of war (the politics of the Xia and Shang kingdoms were destroyed due to unpopular politics, and the princes of the four sides should take this as a lesson and summarize the lessons and lessons). 'The state of Qin must learn the lesson of the demise of the state of Jiang. ”

In the second year of the destruction of the river (the fifth year of Lu Wengong), the chariot of the Chu State went north again, and the target of this time was the Six Kingdoms and the Tateshi Kingdom. The Six Kingdoms were located in present-day Lu'an, Anhui Province, and were founded by the descendants of Gao Tao (Shao Hao's son); The Tateshi Kingdom was located in the northeast of present-day Gushi, Henan, and was founded by the descendants of Tingjian (the son of Zhuan).

The Six Kingdoms were originally vassal states of the Chu State, but later took advantage of the civil strife in the Chu State to fall to the Dongyi group. In the autumn, Yin Chengda was ordered to destroy the six countries. In winter, Wang Zixie led his division to exterminate the knotweed.

Zang Wenzhong was deeply saddened by the demise of the two countries, and said: "The ghosts of Gaotao and Tingjian cannot be sacrificed!" The monarch is morally degraded and cannot serve the great powers, and the country has no foreign aid, so it is reasonable that it will perish. It's so sad and lamentable! ”

After the destruction of the above three countries, the state of Chu expanded its territory to the Rushui Valley.
