On the first day of the eighth month of the summer calendar (October 17 of the Zhou calendar), the Jin army tied the capital like an iron bucket; There is no way to escape, only to defend desperately. The Jin army first carried out several tentative attacks, and they found that the enemy's defense was very tight and the will to fight was very strong.

Xiangong neither likes to fight fortified battles, nor is he too sure about sieges. He asked Guo Yan if the Jin Kingdom would be able to achieve a final victory. Guo Yan replied, yes.

Xiangong asked the deadline again, and Guo Yan said: "On the way, the minister heard the children singing: 'Bingzhi morning, dragon tail Fuchen, all serve Zhenzhen, take the grace of the Yu; The quail is a ben, an army in the fire, and the public is running. 'The kingdom of Yu uses a weekly calendar, and the third day is the first day of the twelfth month; Converted to a summer calendar, it should be at the turn of September and October! In the early morning of the second day, the sun travels to the end of the night, the moon passes through the sky, and the quail fire comes out of the south; It should be then that our army will win. ”

Xiangong asked Guo Yan not to divulge the secret of heaven, and then gathered the generals together to study the siege plan. Among the participants, Zhou Zhiqiao was undoubtedly a special figure, and he gave a detailed introduction to the structural characteristics and defense system of Shangyang, as well as the combat characteristics of Yu Gong and each general.

The Jin people formulated a battle plan based on the battlefield survey and the information provided by Zhou Zhiqiao. After the meeting was dismissed, Duke Xian left Zhou Zhiqiao alone, and he asked Zhou Zhiqiao to secretly get in touch with the party henchmen in the city and wait for an opportunity to make a move to cooperate with the Jin army's battle plan.

The war against the Kingdom of Yu was fierce and arduous: the Jin army attacked the city day and night, and the defenders were undaunted to retreat; The Jin soldiers even climbed to the top of the city several times, but they were eventually thrown to the city by the Yu army. Jin Xiangong and the generals looked at the corpses piling up under the city wall, and they were heartbroken and anxious.

The day of the second child is coming, but the boat is gone; Even Xiangong didn't know whether he had slipped into the city or died in the corpse. On November 29, Zhou Zhiqiao sent news from the city, asking Xian Gong to concentrate his forces on the east and north gates in the early morning of the third day to attract the attention of the defenders, and at the same time set up an ambush at the west gate; He will open the west gate and welcome the Jin army into the city.

Since Xian Gong had never leaked his conversation with Guo Yan to anyone, and the date of the breaking of the city in Zhou Zhiqiao's intelligence coincided with Guo Yan's identification, Xian Gong couldn't help but shout: "God help me!" ”

So he sent a letter to the Emperor the next day, asking for a two-day truce so that they could collect the bodies of the dead. At this time, Yu Ren also felt exhausted, and Yu Gongchou arrogantly agreed to the Jin people's request.

The people of Yu want to take this opportunity to take a good rest. But at the very next dawn, the Jin army suddenly launched another onslaught from the north and east, and the unprepared defenders got up from their exhaustion and slumbered or dragged up, stumbling to the defensive position, and the scene was chaotic. At this time, Zhou Zhiqiao and his henchmen led a group of outlaws to kill the guards of the West Gate and open the city gate; The Jin people who had been ambushed nearby in advance swarmed in, and Shangyang fell.

The Jin army marched into Shangyang, but Jin Xiangong searched the whole city and did not find Yu Gongchou, and later it was reported that he disguised himself as a civilian and drilled out along the drainage ditch of the city wall; Zhou Zhiqiao smiled and said to Xian Gong that this is how he got into the city. Yu Gongchou fled to Jingshi, and was sheltered by Zhou Tianzi, and finally died there.

Jin Xiangong took very drastic measures to deal with the defeated, and if it weren't for the intervention of the important ministers, the famous families of the Kingdom of Yu would have been slaughtered. Xiangong left Rick and Zhou Zhiqiao to deal with the aftermath, and he himself led a large army and returned to the Jin Kingdom with the spoils of war.

The Jin army was stationed on the outskirts of the capital of Yu. At that time, Yu Guo was preparing for a sacrifice, and Jin Xiangong gave the Yu people a huge amount of loot to show his gratitude to Yu Guo for taking advantage of the Tao; Duke Yu warmly retained Jin Xiangong, invited him to stay in the capital for a few days, and attended the ceremony as a special conquistador.

In fact, the plan to eliminate Yu was formulated when he returned to the teacher, and now he has begun to implement it. That night, Jin Xiangong stayed in the Taimiao in the palace. At midnight, Xian Gong led the guards to attack suddenly, and some of them broke into Yu Gong's dormitory and captured him alive; The other part seized the gates and put the outside army into the city. The Kingdom of Yu, the Grand Duchy that was even older than the Zhou Dynasty, was destroyed silently overnight.

Xun Xi escorted Duke Yu and Doctor Jing Bo, Baili Xi and others to Jin Xiangong. For these people, Jin Xiangong felt that they could neither be killed, nor used, nor sold into slavery or imprisoned, and he didn't know what to do with these hot yam eggs for a while.

Jia Hua, the general on the right, said: "It is better to send this group of people to the Qin State as Bo Ji's dowry, as for how Qin Bo treats them, it has nothing to do with the prince." "It turned out that Qin Mugong had a conflict with the people of Yu in the Maojin area in the early years of his ascension to the throne, and Qin Mugong dreamed of killing Yu Gong, and the fat old man of Yu Gong was a heavyweight gift for the people of Qin. Xiangong praised and immediately approved the plan.

After that, Xun Xi brought the BMW and jade bi that were given to Yu Gong to see Gong Xian. Xian Gong grabbed the horse's bridle, opened the horse's mouth and looked at it, saying, "The jade is still the same jade, but the horse has become old." ”

On the issue of dealing with the deceased people of the Yu Kingdom, Xiangong adopted a gentle policy: the nobles basically retained their property, but the land was exchanged for other places; The Jin built a simple temple for the Yu people on the outskirts of the capital, moved the god to the temple, and placed the son of the Yu Gong there, and gave him a small piece of land to continue the sacrifice to the Taibo, Yu Zhong, and the successive monarchs of the Yu State.
