In 263 AD, after the policy of rest and recuperation was implemented, Wei's strength was greatly enhanced and the combat effectiveness of the army was significantly improved. Compared with Shu and Wu in the Three Kingdoms period, Wei had overwhelming advantages in all aspects. Under this favorable condition, Zhong Hui, the general of Wei State, led an army of 1.8 million, and the soldiers attacked Shu State in three ways. Wei Yan, a general guarding northern Shu, wanted to defend Jiange and Wei Jun according to his geographical advantages. Zhong Hui has been a fool for such a long time. He thought he was on an expedition from Wei to Shu, and his soldiers, horses, grain and grass could not stand the test of time. At this moment, I suddenly thought of a plan to let Wargo lead 30,000 soldiers to sneak into level tone and surprise Chengdu. Although it was a risky move, it was a shoo-in and the result was unexpected.

Wargo's troops arrived at the gates of Chengdu, and Liu Chan, who was trapped in Chengdu, did not resist, so he led the civil and military officials to surrender in Kaesong. At this point, Shu, which had existed for forty-two years, perished. At that time, there were tens of thousands of military forces in Chengdu, with plenty of food and grass, and reinforcements from all walks of life were coming, while Wargo had only thirty thousand military forces, so why did Liu Chan surrender in Kaesong?

When Wargo destroyed Zhuge Zhan's main force in West Shu in Mianzhu, the small court in West Shu was very scared and began to discuss the future of the regime and the emperor Liu Chan. Someone suggested: "Shu and Wu formed an alliance and should belong to Sun Wu in the east." Some people say: "The seven counties south of Xishu are extremely dangerous, and it is easy to defend but difficult to attack, so they should move to the south." However, more ministers know that the tide is gone and they don't know what to do, so they have to keep their mouths shut and keep silent. What King Beidi said in this discussion is unknown to future generations. The most likely thing is to echo the ministers' motion, surrender to Wu Dong or establish an exile government in the south and south. At this time, Qiao Zhou, who has always been neglected, stood up and put forward several unquestionable reasons to oppose it: First, since ancient times, he has never been sent to other countries to be emperors; I fled to Wu today, so I should surrender to Wu. Second, obviously, the big one can swallow the small one, and the small one can't swallow the big one. Admit this, and you will know that Cao Wei can annex Sun Wu, but Sun Wu cannot annex Cao Wei. Instead of surrendering to Sun Wu, a small country, how to surrender to Cao Wei, a big country? Third, modesty is a shame. Surrender to Dongwu means surrender to Cao Wei again. Where can I lose face again? Drop Wu first, then Wei! Instead, it is better to surrender to Cao Wei in one step. After blocking this road, Qiao Zhou changed the subject and blocked another road from south to south. First, if you want to move the capital to the south, you should plan ahead and make good arrangements. Only in this way can you stand there. In Enemy at the Gates today, the disaster of national subjugation is just around the corner. From courtiers and scholars to soldiers and civilians, it is hard to say who is loyal and reliable and who is not. I'm afraid there will be an unexpected mutiny on the day when the emperor leaves. Where can you escape to the south? Although everyone has lost the power to fight back, they are worried: "Today, Wargo is about to arrive in Chengdu, and it is just around the corner to break the city and destroy the country. If he refuses to surrender and gives us a decent chance to step down, what should we do? " Qiao Zhou said: "Fang has not surrendered to Cao Wei, and the situation determines that Cao Wei has to accept the surrender of the West Shu Kaicheng. After surrendering, I will be treated with courtesy. " Probably seeing the hesitation, Qiao Zhou then patted his chest and said, "After your majesty's surrender to Wei, if Cao Wei doesn't crack the soil and seal you, I will ask to go to Kyoto and fight for justice."

If your majesty goes south today, the officials and people in Yizhou will either be killed by their parents or leave their homes, and the flight or rebellion will inevitably accelerate. I hope your majesty will make a decision to surrender as soon as possible, and Cao Wei will still get the title land, so don't surrender after going south, as that will be a serious disaster. "

Liu Chen, the king of the northern land, regarded Yizhou regime usurped by his grandfather Liu Bei as private property. After his father Liu Chan decided to surrender, he went home and killed his wife cruelly, then committed suicide, and became a martyr for the regime of Xishu in despair.

The suicide of his son, Liu Chen, did not bring him a glimmer of hope, nor did it inspire the officers and men in West Shu to swallow mountains and rivers. In front of Liu Chan, there is no other way but to surrender. After some preparation, he tied himself up and let people carry coffins, and Kaicheng surrendered to Wargo, thus ending the warlord regime of Liu and his son for 53 years since AD 208.
