In fact, Cao Bao's whereabouts are under Yuyi's control, and opening the city gate is also a part of Yuyi's strategy.

However, Yuyi's only miscalculation was to protect Liu Bei's family, focusing on dealing with Lu Bu and protecting Zhang Fei, and this detail was ignored.

After Zhang Fei came out of Xuzhou, less than ten people, Cao Bao had a grudge, so he took advantage of their drunken and unconscious, with hundreds of people to chase, Zhang Fei saw Cao Bao, knowing that he must not be able to get rid of all this, he felt very angry, so he came to him for a decisive battle, fought three rounds, Cao Bao was defeated, and retreated.

At this time, a pair of people suddenly came, it was Yu Yi and Chen Deng who felt, Yu Yi used the flying knife technique, hit Cao Bao's arm, Cao Bao was injured, ran to the river, Zhang Fei took the opportunity to go up and stab Cao Bao in the back of the heart with a shot, and even the man and the horse died in Hezheng

Thinking of the other people in the city who had not yet escaped, Zhang Fei suddenly burst into tears and said regretfully: "These are all my faults!" ”

Yuyi patted Zhang Fei's shoulder and was indifferent.

Suddenly, someone came to report that the other people in the city had escaped, and they had killed a lot of Lu Bu's soldiers, Zhang Fei inquired about the situation, it turned out that Yuyi sent them to lurk in various parts of the city, and when Lu Bu led five hundred people into the city completely, in the dark, he shot Lu Bu behind him with a bow and arrow, so that he was caught off guard.

Zhang Fei then remembered why Lu Bu didn't attack him with all his strength after meeting him, and his expression was nervous, it turned out that someone was attacking his rear.

Zhang Feibai fell to the ground and said, "If it weren't for my brother's assistance, I'm afraid I wouldn't have been able to come out alive." ”

"Wherever the third brother says, they are all his own brothers, but Xuzhou City can't be saved!"

Yuyi sighed.

"Hey, it's all caused by my greed for drinking, so what can I do?"

Zhang Fei felt very remorseful.

Chen Deng stood up and suggested: "The only way to do this is to go to Huainan to find Liu Yuanjun and then figure out another way." ”

Yuyi nodded and said, "Now that Lu Bu has occupied Xuzhou, although we have taught him some lessons, he will be able to recover soon, maybe now that he has gone out of the city to catch up, we should set off quickly." So Zhang Fei took everyone and walked in the direction of Huainan.

After Lu Bu entered the city, he pacified the residents of Xuzhou, and at the same time counted the casualties, in addition to Cao Bao's death, half of the elite troops he brought were also killed, which can be described as a heavy price.

After a while, Chen Gong also entered the city, and Lu Bu couldn't figure out some things, so he asked: "Isn't Zhang Fei drunk, when I met him, the wine hadn't fully woken up, why is there still a resistance force in the city hiding in the shadows and sneaking up on us." ”

Chen Gong actually noticed this, just at this time Gao Shun came over and informed Liu Bei's family of the situation that they were still in Xuzhou, Lu Bu hurriedly sent someone to guard the door of the residence, and ordered that they should not enter at will.

And the rebellion of Xuzhou has also become a mystery. It wasn't until Gao Shun arrived that he knew the situation. It turned out that Gao Shun caught a secret whistle, and learned that it was Yuyi who learned the news of Cao Bao in advance, and deliberately planned it, and then arranged an ambush for the living forces of Xuzhou.

Zhang Fei and everyone soon came to Liu Bei's temporary camp in Huainan, and reported the situation in Xuzhou to Liu Bei.

Everyone was very surprised after hearing this, Liu Bei sighed: "What kind of heart do you have when you get it, and what kind of sadness do you have if you lose it?" ”

Guan Yu said: "Forget if Xuzhou City is lost, what about my sister-in-law?" ”

Zhang Fei replied: "They are all back in Chengzheng"

Liu Bei shook his head, and there were no words during the whole process.

Guan Yu complained: "What did you promise when you were defending the city, do you remember?" What did my brother tell you, now that the city is lost, and my sister-in-law is also in the city, what should I do! ”

At this time, Yu Yi stood up and said: "I am also responsible for this matter, I didn't pick up my sister-in-law in advance, I just thought about protecting the third brother and using the residual strength to make Lu Bu pay the price." ”

Zhang Fei stopped Yuyi behind him and said, "It's all because of my drinking, let me fall under the law now!" "Draw your sword and prepare to kill yourself on the spot!

Seeing this, Liu Bei hurriedly stepped forward to hug it, threw the sword aside, and said: "Brothers are like siblings, wives are like clothes, clothes can be sewn and mended if they are torn, and their hands and feet are cut off, what is next?" The four of us Taoyuan are righteous, not seeking to live together, but to die together, although we have lost our city family now, how can we bear to let my brother die like this, not to mention that Xuzhou was originally imposed on me by Tao Qian, and it did not belong to me in the first place, although my family was robbed, I believe that Lu Bu will not murder him, and he can find a way to rescue him. Third brother, you are just a momentary mistake, and you will not pay for it with your life! After crying, Guan Yu and Zhang Fei both cried.

Yu Yi felt the atmosphere of the scene, and also began to sob, Liu Bei cried for a while, walked up to Yu Yi, and said: "It was the eldest brother who blamed you before, and I hope you can forgive me!" ”

This sentence made Yu Yi feel very warm, the tears in his eyes could no longer be held back, and he came out of his eyes, the four brothers were together, Yu Yi suddenly felt that he was so confused at that time, how could he speculate about the eldest brother like that, he was really narrow-minded.

This incident further eased the relationship between the four brothers, forming an unprecedented picture of unity.

Yuan Shu heard that Lü Bu had attacked Liu Bei's rear and had already occupied Xuzhou, so he sent Ran Lü Bu's place and promised to use 50,000 pieces of grain, 500 horses, 10,000 taels of gold and silver, and 1,000 colored satin to let Lü Bu attack Liu Bei with him.

When these interests were put in his hands, Lu Bu's true face was exposed, and he immediately sent Gao Shun with 50,000 troops to attack Liu Bei's rear.

By the time Gao Shunjun arrived at the place according to the time, Liu Bei had already left.

Gao Shun saw Ji Ling, and the two had a meeting, so they asked him for supplies as requested. Ji Ling said: "Please go back first, let me report to the lord!" ”

So Gao Shun said goodbye to Ji Ling, withdrew his troops and went back, told Lu Bu about the actual situation, and talked about his own opinions, Lu Bu felt a little hesitant.

Suddenly, someone reported that Yuan Shu sent a letter, Lu Bu opened it and read the contents, and said: "Although Gao Shun came according to the requirements, Liu Bei has not been removed, and when Liu Bei is arrested, I will send those materials to you!" ”
