As mentioned earlier, the Qing brothers of Chen Guo colluded with the people of Chu to play a little trick, and as a result, they deceived Chen Aigong back from the princes' conference. Chen Aigong stayed in China for two days, and then rushed to Chu State non-stop. He prostrated in front of the king of Chu Gong, burst into tears, and begged him to return Gongzi Huang to him; The king of Chu Gong helped him up with a pleasant face, saying that everything was easy to discuss. The two carried out a bloody ceremony, Chen Aigong swore that he would never betray Chu, and the king of Chu Gong handed over his son Huang to him and took him away.

The Jin Mourning Duke was furious, and the princes were deeply worried. On the tenth day after Gongzi had eliminated his political enemies, he received an order to invade the state of Cai. The battle plan of the Jin people was to first cut off the connection between Cai and Chen in order to prevent Cai from saving Chen, and then raise troops to attack Chen.

Gongzi immediately recruited an army and handed over command to Gongzifa and Gongsun Yu (Gongzi's son, Zi'er). The two led their army all the way south, and a few days later besieged a border town in the state of Cai.

Cai Jinggong ordered the great Sima Gongzi Xie to lead the troops to resist the enemy. Gongzifa divided the army into two parts, one led by Gongsun Yu to attack the border towns, and the other led by him to ambush the Cai army on the way to rescue.

Gongzixie was overconfident, and he thought that the Zheng people could not use any means in their own country, so he ordered "full speed march", claiming that the Zheng people would "be driven into Yingshui to feed Wang Ba". As a result, the army was ambushed by Gongzifa as it passed through a dangerous place. Cai Guoren ran so much that he vomited blood, and he didn't even have the strength to wield his weapon.

Childe did not want to kill more, so he ordered not to kill or wound the enemy who had lost the ability to resist, and as a result, he captured the commander of the enemy army and a large number of soldiers.

Zheng's army then captured the border towns of Cai. Zheng Jun returned victorious, and the office was filled with a festive atmosphere: the countrymen shared the spoils of war, and the doctors celebrated with crowns.

At a celebration banquet, the doctors kept toasting Gongzi and congratulated him on his major victory, and the atmosphere was very warm. At this time, a young voice came from a corner somewhere: "A small country has established martial arts without Wende, and this disaster is a big disaster." The people of Chu will definitely come to crusade against our country, will we be able to choose to give in at that time? If you don't accept it, you will be attacked, and if you give in, the army will come. Then the next round of submission and beating begins. Jin and Chu fought against Zheng, and without four or five years, Zheng Guo would not be able to achieve peace. ”

The doctors followed the sound and looked at it, and saw that it was Ziguo's son Gongsun Qiao (Zi Chan or Zi Mei) who had just finished the crown ceremony. When Childe saw that his son was openly contradicting him, he couldn't help but feel a loss of face. He said angrily, "What do you know! The country has a great destiny, and it is issued by Zhengqing. You little kid talks nonsense, I don't know how you're going to die! ”

Gongsun Qiao wanted to open his mouth to object, but was stopped by his cousin Gongsun Yu.

In May, the monarchs of Jin, Lu, Qi, Song, Wei, Zheng, and Yi met in Xingqiu, and the six-year-old Duke Zheng Xi, accompanied by Gongzi Xi, the official of the courtesy, offered prisoners to the Duke of Jin.

After the ceremony, a banquet was held in which only doctors from all over the world attended. The banquet was presided over by Bank of China, who placed Zisi last in the toast to the guests, and demoted him to the level of Dr. Yi Guo, which was a great insult to Zheng Guo.

After the meeting, Zhongxingyan found Zisi again, with a gloomy light in his eyes, and said: "Zihu's two sons have run to the Jin Kingdom, and they are all in my house. I don't care how my duke died, I only care whether the successor will satisfy my country. Zi Si suddenly felt an electric current pass through his entire body, and his heart was full of fear. Zisi understood that Zhongxingyan's words were not just threats, and if Zheng Guoren "could not satisfy the Jin people", the Jin people would be tired and die on the journey.

On the other hand, the prophecy of the child was soon fulfilled. The Zheng people's invasion of Cai did cause a big disaster. The most angry is Ling Yin Zinang, who is determined to restore his former hegemony, but as soon as Chen Guo is pulled over, Zheng Guoren came out to smash the field. The king of Chu Gong ordered Yin Zi to attack Zheng. Zi Nang decided to settle the matter, and if he could not make the Zheng people submit, he would erase Zheng Guo from the territory of the Spring and Autumn Period. Zi Nang had been preparing for the war since the summer, gathering troops, making siege equipment, and then beginning various tactical training; He also recruited auxiliary armies, miscellaneous servants, baggage, and pack animals from neighboring nations and tribes.

After the winter, the Chu army was fully prepared to go on the expedition, so it confidently went north to attack Zheng. The allied forces went north out of Fangcheng Mountain, crossed Rushui and Yingshui, first surrounded the former capital of Xu (Xu had already taken refuge in Jin at this time) and captured the target in a short time. The enemy continued north with captured high-ranking nobles.

Zi Nang demanded that the coalition army "fully show its anger against Zheng Guo, but not kill innocent people, and violators will be punished", and as a result, the coalition army became the largest bandit army in the whole world. Where the army passed, towns were destroyed, houses collapsed, and the land was in shambles, and the Zheng people fled with their families and mouths.

The Chu army continued to move north, and the Xinzheng was like an iron bucket.

At this time, the doctors of Zheng Guo had a great disagreement about whether to fight or peace: Gongzi Jia (Zisi's brother Zikong), Gongsun Yu (Gongzi Yan's son?? ), Gongsun Shezhi (Gongzi Xi's son Zizhan) advocated sending envoys to the Jin State for help; Gongzi Luo, Gongzi Fa, and Gongsun Lu (Zi'er, the son of Gongzi who went to illness) hoped to negotiate peace with the Chu State. The other doctors stood on the side of their superiors and quarreled with the doctors of the same rank opposite.

Both sides have fully expounded their reasons, and neither has been able to convince anyone. Later, Zisi said: ""Zhou Poems" said: 'The clear of the river, how much is life? Zhaoyun inquired a lot, and his job was actually Luo. 'The more clans involved in the scheme, the more dissatisfied the people will be with the outcome, and the less likely it will be. The country is at a critical juncture, and we will obey the state of Chu to resolve the disaster. Once the Jin master comes, follow the Jin kingdom. We respectfully offer coins and silks to serve those who come, which is the way to preserve small countries. Isn't it nice that the enemy can't inflict harm, and people won't get tired? ”

Gongsun Shezhi said: "The reason why a small country can be safe is because it uses faith and righteousness to serve a large country. Small countries have lost their credibility, and wars have come day and night, and the country has no time to die. Zheng and Jin have already held five alliance meetings, and once they reneged on the alliance, although the state of Chu can save me, what is the point?

"Even if the State of Chu treats our country well, our country will not get good results, not to mention that the State of Chu just treats our country as a border town? So you can't take Chu. It's better to wait for the Jin army: the Jin State has just come out of the Ming Dynasty, there is no contradiction between the four armies, and the relationship between the Eight Qing is harmonious, and Zheng Guo will definitely not be abandoned. The state of Chu is far away, and the food is about to run out, so it will definitely not be able to stay for a long time. I heard, 'The rod is not a letter.' 'Isn't it okay to strengthen the garrison to make the Chu division tired, and to wait for the Jin army with a cane?' ”

But Zisi had already been intimidated by the intimidation of Zhongxingyan, and he felt that it was better to simply break off the alliance than to be threatened by his allies. He went on to say: "The poem says: 'Condo, the husband is not needed. Speaking in court, who dares to take the blame? If you are a bandit, you can't use it. 'Are you entitled to be held accountable for making a wrong decision?' So please follow Chu, all the responsibility is borne by me alone. ”

The decision was thus made, and Zisi sent an envoy to the Chu military camp to ask for peace talks with the Chu people. The two men then signed an alliance and held a bloody ceremony, and the Chu army released the captive Zheng people, returned the looted property to the victims, and then turned around and returned home.
