As mentioned earlier, Zheng Gongzi's class established Gongzi as the king during the period when Zheng Chenggong was detained by the Jin people. Later, the doctors staged a coup d'état and killed Gongzi, and Gongziban and his henchmen fled to Xu.

The exiles were warmly welcomed by Xu Linggong, who hoped that the exiles would eventually return to Zheng and drive out Zheng Chenggong. If the wish is realized, Zheng Guo will have a regime that is friendly to Xu Guo.

In the summer of this year, Zheng Chenggong and his doctors led an army to march west with the Jin division to conquer the Qin State, and the prince defended the country; There are no heavy troops in the country, and it looks very empty.

Gongziban and his brother Ziyu thought that the opportunity had come, and happily prepared to return to China to make a big move: this time he wanted to overthrow Zheng Chenggong's rule and establish himself as king. Xu Linggong was so happy that he immediately gave them a large amount of money, weapons and equipment, and fifteen chariots.

Gongziban led a group of people through the border of Xu Zheng, and in front of him was his base camp - Ziyi. After Zheng Chenggong was reinstated, he sent a world-famous figure for his cruelty, Gongsun Wu, to serve as the doctor of Ziyi. Gongsun Wu was also a political enemy of the childe class, and as soon as he took office, he began to purge people related to the childe class. In order to curry favor with Zheng Chenggong, but also to vent his grievances against Gongzi's class, and in order to make profits, Gongsun Wufu did a lot of outrageous bad things, he continued to expand the scope of attack, and finally offended all the aborigines.

Gongziban hid his whereabouts, and he first sent a few cronies into the city, and those people contacted several family leaders, and the leaders gathered their families. One night, Gongziban and his followers quietly came to the west gate, and the aborigines killed the soldiers guarding the gate, and then opened the city gate to let Gongziban enter the city. The rebels immediately poured into the officials' quarters, only to have Gongsun Wu and his subordinates torn to pieces by the angry soldiers and disarmed before they could assemble their troops.

The people gathered around Childe's class, carried him on their shoulders, and sent him to the square in front of the Ming Hall. At this time, countless people with torches had gathered in the square.

Childe Ban boarded a chariot and said to the people, "I'm coming back late, you're suffering!" "The people wept bitterly when they remembered the ordeal they had endured during this period. Gongziban accompanied the people to shed tears for a while, and then continued: "Back then, the prince was detained by the Jin people, and the country had no owner, so I became the king." I never think about my own self-interest, and what I do is good for the public.

"But the son has no way to kill. After Junbo was reinstated, I immediately expressed my loyalty to Junbo, but Junbo was bewitched by Gongzi, and not only did not listen to my explanation, but instead decided that I was a usurper, and sent Gongsun Wu here. If I want to usurp the throne, why should I stand up? Why don't you take the position yourself? Besides, you all know that Gongsun Wu is a vicious dog raised by Gongzi, who climbed to a high position by persecuting innocent people and gaining the trust of the monarch by flattery.

"So, all this is the result of Gongzi's conspiracy, he wants to occupy Ziyi by persecuting me, and he can only send his own people into Ziyi by destroying you. So it doesn't matter if I'm here or not - you're dead. In this case, there is only one way left before you: the only way to end your suffering is to kill Gongzi.

"Gongzi has many enemies, and I still have strong supporters in Xinzheng; As long as we enter Xinzheng, at least half of the people will support us. And as soon as Gongzi dies, I will tell the truth to the world, and the prince will regret it, and he will restore my official position, and you can continue to maintain your freedom and status. If you want to live, come with me, and I won't force it if I'm afraid of death, but every time you have one more, our hope of victory will be greater. ”

Supporters cheered loudly with torches, but most remained ominously silent, and Childe rewarded each supporter with a sum of money. The next day, he looked at the team around him and felt that there was still a shortage of manpower, so he recruited a group of outlaws with a lot of money. Then he led this group of rebel forces to rush towards Xinzheng with great momentum.

Zheng Guoguo had several old men in addition to Gongzi at that time. For various reasons, they didn't know what was going on in Ziyi. Sometime in mid-June was the day of Zheng Mourning's death, and the doctors were busy preparing for the sacrifice.

The spies of the Childe class were the first to infiltrate Xinzheng, and they quietly found the henchmen of the childe class and told them the plan. On the night of June 15, the henchmen in Xinzheng City eliminated the soldiers guarding the gate and opened the gate to let Gongziban in. Rioters stormed the streets of Kui in droves, armed with torches and weapons, emboldening themselves with rude language and shouts. The rebels rushed towards the temple with torches, but they were stopped by Gongzi and the palace team halfway down the road.

Neither side could figure out the details of the other, and neither dared to rashly launch an attack. Childe ordered Childe's class to withdraw from the capital. But Gongziban said that they rushed back to worship Zheng Mourning Gong; No one is qualified to prevent a prince from entering the temple to offer sacrifices to the ancestors.

Gongzi was furious: "It has been three years since you were convicted and fled, during which time you have neither asked the monarch for forgiveness, nor have you shown repentance, nor have you ever returned to China to participate in a sacrifice; Now he took advantage of the monarch's war to break into the capital with this group of subordinates, falsely claiming to sacrifice to the ancestors? I will never allow you to desecrate the temple! If you don't retreat, I'll kill you!" ”

Childe's class was shocked by Childe's aura, and his left and right instigated him to attack the enemy immediately, Childeban's swallowed spit and said: "My friends are not ready, I don't want you to die in vain, let him live one more night." Wait for tomorrow to join forces with reinforcements, and then kill Gongzi. ”

In this way, he did not dare to fight the palace guards, nor was he willing to withdraw from the capital, so he decided to retreat to his old mansion to make another plan. Childe Ban led the rebels to retreat slowly, and Childe did not dare to force the enemy, he just ordered to hold on to various important defensive points.

The mansions of Gongziban and Gongziyu have been owned by Dafu Ziyin and Ziyu, and these two people were originally political enemies of Gongziban; At this time, the rebels should not be allowed to seize their homes. The two doctors armed all the people in the family who could be armed, and personally led the family to resist the invasion. But there were so many rebels that the two families were broken in a matter of moments, and the two doctors were finally killed because they were outnumbered.

Gongzi didn't dare to go to the rescue—he had too few troops in his hands; And although there are not many people in Xinzheng City who support the child's class, there are many people who hate themselves. Gongzi's belief is that as long as the enemy does not attack the Gonggong Palace and Taimiao, he will never take the initiative to attack.

The whole city spent the night in a state of anxiety. Gongzi sent many lobbyists to the homes of the major clans, begging, demanding, or threatening them to help the office fight the traitors; On the other hand, Childe's class is doing the same thing, except that he uses threats much more often than Childe.
