In fact, when Guo Yingyi and Du Ji sent people to Chang'an for help, the Cui brothers had already realized the seriousness of the matter, and as the envoy of Jiannan Jiedu, he could only really control the surrounding states of Chengdu and Jinniu Road, and he could not block Lychee Road at all.

Guo Yingyi and Du Ji concentrated all their forces in Yuzhou, which was enough to ensure the smooth passage into Shu.

Cui Ning knew that if he waited like this, he would sit back and wait, he had lost the initiative and had to take it back with his own hands.

He and his brother Cui Mi led the unity battalion out of the nest, and only sent some weak remnants to provoke under the city of Yuzhou, in an attempt to induce the other party to fight them in advance.

However, this kind of strategy did not work for Guo Yingyi and Du Ji, who knew the strength of the unity camp well, and besides, they were not people who dared to take risks and be greedy for great achievements. As long as they retreat behind Yuzhou City to ensure the safety of the Lychee Road into Shu, Li Siye will naturally send elite superior troops to quell the rebellion, and this kind of credit is nine out of ten.

After Cui Ning Cui Mi's siege failed, he finally determined that the situation was not good, hurriedly withdrew to Chengdu, and requisitioned a large number of grain and grass to hoard, once the imperial army arrived, they could only retreat to defend.

At the end of October, Zang Xiyan led his army to Yuzhou, and after the three parties converged, they determined the unanimous leadership and began to march along the Shuzhong Basin to Chengdu, and finally lined up under the city wall.

The Cui brothers' foundation in Chengdu City is not stable, and the grassroots officers in the unity camp generally do not have any hope that they can control Shuzhong, since the decision to rebel for a month, their sphere of influence is still two hundred miles around Chengdu, not to mention that Chang'an has personally sent troops to the field, how can a small arm be twisted over a thigh.

Zang Xiyan not only fought very slippery, but also a good hand at manipulating people's hearts, after he led his troops into the city of Chengdu, he did not directly attack the city, but sent soldiers to continuously shout, and sent people to the city to launch cloth communications.

King Yong said that he did not understand the situation in Shuzhong, and the establishment of a staff system in the army should have been gradual and gradual, which caused the high-level of Shu to react aggressively, not only would he not pursue the majority of officers and soldiers in the unity battalion, but even Cui Ning and Cui Mi brothers would be lightly punished.

Many soldiers and grassroots officers of the unity battalion have picked up such cloths, and when the information reaches Cui Ning and Cui Mi, the entire unity battalion will already know about it. The biggest disadvantage of people in high positions is that the delay in the transmission of information is too long.

Cui Mi came to his brother with an arrow wrapped in cloth, and said with a solemn expression: "Brother, please look, this is the besieging army shooting in tonight. ”

Cui Ning carefully read the contents of the silk book, and couldn't help frowning, Cui Mi asked tentatively next to him: "Brother, look, does King Yong mean to let us go." ”

"Lie to the ghost," Cui Ning patted the case table with his palm and reprimanded his brother for not firmly harboring illusions about the enemy: "Intercepting the imperial court and supporting the army to stand on their own, which one is not a major crime of killing the head, Li Siye is not as weak and easy to fool as the Li Tang royal family, he has the intention to kill!" He has sent a large army to the city, and you can imagine how serious this matter is! ”

"Once you and I listen to him, withdraw our defenses, go out of the city and surrender, strip off our military power and be sent to Chang'an, then it will be the swords and I will be the fish."

Cui Mi sighed and said, "You and I don't believe the nonsense of the imperial court, but I can't guarantee that the brothers under my command will believe it." ”

Cui Ning's head suddenly cooled, and he asked in a cold voice, "What does this mean?" ”

"More than one arrow was fired by the enemy, and hundreds or thousands of silk books wrapped in strips of cloth fell in the city. The rest was picked up by the brothers. ”

"Bastard! Finished! Cui Ning stomped his feet hysterically, and then looked up to the sky and sighed: "Are you and my brother going to die in this Chengdu city today?" ”

He suddenly turned to Cui Mi and asked, "How many people in the solidarity camp are really loyal to you?" You can not be afraid of the temptation of the enemy's division. ”

Cui Mi didn't understand what he was going to do, and said vaguely: "Three thousand, no, two thousand!" ”

"I also have a thousand tooth soldiers under my command, before some people open the city gate against the water, you go back and pack up the gold and silver, and I will also take some things, we will lead these 3,000 people to Tubo, and use the power of Tubo to snatch back Shuzhong."

"Wait." Cui Mi asked in a daze: "He may accept us if we go to Tubo, but how can they help us recapture Shuzhong, and are they willing to do things that are not beneficial to Tubo?" ”

Cui Ning snorted: "Of course not, I will exchange Shu County for more than ten prefectures and thirteen prefectures of the West Baoning Prefecture in exchange for the conditions for Tubo Zampu to send troops, and at the same time nominally submit to Tubo and accept Zampu's canonization." ”

Cui Mi opened his mouth wide in horror: "Are you going to betray the country for glory and be willing to be a national thief?" ”

"It's true to be a national thief, but I am a traitor to survive, if your brother doesn't take refuge in Tibet, it will be a dead end. I'm just trying to preserve myself by using the power of Tibet. ”

Cui Mi can't reprimand her brother's actions, no matter when they are tied together, they are always tied together.

He immediately went down to gather his generals, gathered some of his cronies and their men, and waited for Cui Ning's order to withdraw from any gate of Chengdu City.

The people in the unity camp in the city were panicked, and the low-level officers didn't know what Cui Ning was thinking now, they secretly didn't know how many times they discussed, and came to the conclusion that Cui Ning would never be buried with him, but he would also be given the opportunity to surrender in person.

They waited for about five or six days, and the Yong army led by Zang Xiyan also waited outside the city with confidence, knowing that if Cui Ning resisted stubbornly, most of the soldiers in the city would not follow him.

The sudden news came sixteen days later, and suddenly Cui Ning's tooth barracks and Cui Mi's cronies disappeared from the city overnight.

Before the Cui brothers fled, they blocked the news, only the two of them and a few cronies around them knew, they pretended to make a plan to attack the enemy army at night, and then gathered 3,000 guards in the backyard of the Jiedu Envoy's mansion, quickly left the city from the north gate, and fled in the direction of Yazhou.

The first day of the brothers' escape had not yet been discovered, and the army in Chengdu was still patrolling the city walls in a regular manner, but the generals soon found that they could not find the commander, and their way to the Jiedu envoy's mansion was blocked by the steward. But the shrewd generals quickly sensed the anomaly, and the fact that the Cui Ning Cui Mi brothers, who had been patrolling the city walls day and night, now showed that they had not shown up for a long time.

One of these generals is named Zhang Xiancheng, who is an old qualification in the Jiannan Army, but because his father Zhang Shouqi was prematurely belittled by the imperial court, he did not get the glory of his father, and his promotion in the army was relatively slow, and he was only a marching Sima of the unity battalion. However, because of his old qualifications, he still has a lot of weight in the camp.

Zhang Xiancheng realized that something was wrong, and saw the steward's eyes flickering, so he asked with both soft and hard: "Steward Cui, now it's not as usual, the imperial army is under the city wall outside, Dr. Cui and Cui Jun can't come out to preside over the situation, the soldiers will be unstable, once the city is broken, can I afford the responsibility or can you bear it?" When the army enters the Jiedu Envoy's mansion, will you fall to the ground in the same way? ”

The steward snorted and retorted: "Could it be that if you wait one more day, the city will be breached, what does Ah Lang do to raise you generals?" ”

"Do you know how to fight? I don't know what defeat is! If the imperial army invades the city, not only will our lives be lost, but your head will also be moved! ”

The steward shuddered in fright, timidly looked at the several military leaders behind Zhang Xiancheng who were holding their anger, and quickly pulled Zhang Xiancheng aside, and said in a low voice: "It's not that I don't want to reveal it, it's just that there are many people, and I'm afraid that it will cause a big disaster." ”

"Not to mention that the disaster is greater, but now you will only tell me that there is only one person."
