In the summer, Qi Xianggong sent an invitation to Zheng Guoren to join the alliance. At that time, the matter of Qi Xianggong's murder of Lu Huan Gong was spread among the princes, and the princes hated and feared Qi Xianggong. The sacrificial foot persuaded Ziqian to decline the invitation, but Gao Qumi kept encouraging him to go to the meeting.

Zi Qian thought about it again and again and adopted Gao Qumi's opinion. He said that Qi is strong and Zheng is weak, and Gongzi is suddenly entrenched in Liyi, and now that Qi is showing favor to Zheng Guo, he should take the opportunity to make friends with a big country to protect Zheng Guo's safety. Saizu had a premonition that a catastrophe was imminent, and he couldn't travel under the pretext of poor health, so he took Gao Qumi to the meeting.

On July 4, the two sides met at Shouzhi (southeast of Sui County, Henan) as scheduled, and to his surprise, Qi Xianggong brought a large number of troops.

Qi Xianggong has never liked Zi Yan (because the two have had a conflict before), but given that Zi Yan behaved subserviently this time, he didn't hate each other so much in his heart. Qi Xianggong asked Zheng Guo to cooperate with Qi to destroy Ji Guo and help Wei Huigong restore the throne; In return, Qi Guo will help Zheng Guo solve the Zitu problem. Zi Qi fully agreed with the other party's proposal, and the two sides began to feast after blood.

The banquet scene was very warm, and people frequently raised their glasses and talked and laughed loudly. The more they drank, the more speculative they became, the closer they became, and finally they simply squeezed into a table. But just like the last time there was a conflict, after a few hours of drinking, Zi Yan's terrible mouth began to talk nonsense again.

He said, "That old man doesn't want the widow to attend the alliance, guess what the widow said?" The other party replied casually: "Yes, how do you say it?" Zi Qian continued: "The widow said, I am not the Duke of Lu Huan, nor did I marry the sister of the Marquis of Qi; Even if I marry her, I won't take her to the meeting, how can Qi Zhu'er be a widow? Hahaha, what do you think of my answer? ”

Wenjiang is a forbidden place that Qi Xianggong can never touch; Zi Yan's voice was so loud that everyone present heard it, and the scene suddenly fell silent. Qi Xianggong's eyes suddenly cracked, and his face was like pig's liver. He jumped up, hugged Zi Yan's head, and broke his neck in one fell swoop; Before Gao Qumi could draw his sword, he was subdued by the Qi drinking friends around him.

Qi Xianggong placed a charge on the spot for the two: "murder of Zhaogong", so it seems that what he did was righteous. Qi Xianggong escorted Gao Qu Mi back to Linzi, punished Gao Qu Mi for the crime of killing the king, and broke him alive in public; His corpse was thrown into the wilderness for birds and beasts to eat.

Duke Xiang of Qi killed the monarchs of the two countries within half a year, and the princes were shocked by his cruelty, and no one could figure out where the Qi country would go. Lu Zhuanggong said: "If justice cannot suppress evil, what is the use of insisting on justice? "Upholding justice and suppressing evil are two different issues. The only one who can kill that tyrant is someone more evil than him. ”

After Zi Yan's death, Saizu summoned Ziyi back from Chen State and established him as Zheng Bo. Later generations said, "Sacrifice enough to save yourself from calamity because of your wisdom." Confucius said, "That's so." ”

In the winter of that year, there was also a turmoil in the royal family.

King Huan of Zhou had a son named Wang Zike (Ziyi), and his mother was King Huan's favorite concubine. Wang Zike was extremely doted on by his father because of his mother. King Zhou Huan gave his favorite concubine the treatment of a queen and Ziyi the treatment of a prince - he handed Ziyi to Zhou Gong Hei and asked Zhou Gong to teach this child wholeheartedly. You must know that the Duke of Zhou has been the royal family for generations, and only the crown prince can enjoy the honor of becoming a disciple of the Duke of Zhou. Later, it was common to see Wang Zike and the prince dressed like twins, walking side by side with the prince behind King Huan.

Doctor Simber was a close friend of Zhou Gong and an important member of his staff. Xin Bo persuaded the Duke of Zhou: "The concubine is like the queen, the concubine is like the concubine, the country has two Zhengqing, and the scale of the other city is comparable to the capital, these are the causes of turmoil." The first two are already there! Don't be careful! ”

Duke Zhou did not accept Simber's advice, in fact, when he received the order to serve as Wang Zike's teacher, he began to plan to put Wang Zike on the throne.

Simber is still loyal to the Son of Heaven, he feels the seriousness of the situation, and suspects that Zhou Gong has ulterior ambitions, so he still shows his loyalty to Zhou Gong as always, but secretly he is collecting evidence of the crimes of the Wang Zike group.

In the tenth year of Duke Lu Huan, that is, the year of the battle between Zheng and Lu Lang, the right secretary of the dynasty, Duke Lin's father, was forced to flee because he offended King Zhou Huan, and this incident made the royal power fall on Duke Zhou alone.

After the death of King Huan of Zhou, the position of the new king was unstable, and the Duke of Zhou monopolized the government. The Duke of Zhou thought that the time had come, so he planned to kill the king of Zhou Zhuang and establish Ziyi as the king.

Zhou Gong was the first to inform Xin Bo of the usurpation plot, and Xin Bo held back the anger and fear in his heart and expressed his firm support for Zhou Gong's criminal plan; But he turned around and reported the news to King Zhou. King Zhou Zhuang decided to plan the plan, and he and the doctors set a trap; Zhou Gong was completely kept in the dark, so he got in without thinking. As a result, the conspiracy was crushed, the Duke of Zhou also died under the chaotic blade, and Wang Zike fled to Nanyan.
