Cao Cao did not really retreat, but withdrew the troops besieging the city on three sides, and the 200,000 troops were all stationed in the west of Tancheng. After the Dongda camp was broken through by Liu Zeqing, Cao Cao also realized the severity of the problem, and opening his five fingers to hit people was not as powerful as clenching his fists. Now that the reinforcements from Qingzhou are coming, if they continue to besiege the city on all sides, it is easy to be broken by the reinforcements from Xuzhou and Qingzhou, so Cao Cao chose to set up a large camp in the west of the city.

Liu Ze personally went out to the west gate to investigate, Cao Cao's camp was extremely strong this time, with deep trenches and high fortifications, and he was heavily guarded, and now he would definitely suffer a lot if he wanted to do some tricks such as raids.

However, after Cao's soldiers withdrew from the siege, the internal and external traffic of Xuzhou City was restored, but Liu Ze was not prepared to transfer the army of the Zhangshan battalion into Xuzhou City. Once the whole army enters the city, Cao's soldiers will return to the siege, and the situation of Xuzhou City will be restored to its original state. Therefore, Liu Ze ordered Guan Yu and Tian Kai Kong Rong to still be stationed in Zhangshan, and at the same time strictly guarded.

Tao Qian and the military attachés of Xuzhou secretly breathed a sigh of relief, this Liu Zefang came, and solved the crisis of Xuzhou, although Cao Cao still did not retreat, but at least Xuzhou City has passed the most critical moment. However, in the following troop strategy, the generals of Xuzhou had a great divergence.

The officials headed by Cao Bao insisted on sticking to the fortification, believing that Cao's army was too powerful to fight with it in the field, and that they had to rely on the fortified city and thick walls to defend the city, and they would naturally retreat after Cao's soldiers ran out of food.

Chen Deng and others insisted that Cao Bing was newly defeated. The Xuzhou army should be vigorous and cooperate with Qingzhou reinforcements to expel Cao Cao from Xuzhou, and Cao's soldiers stayed in Xuzhou for one more day, and I don't know how many Xuzhou people were slaughtered.

Tao Qian was at a loss and asked Liu Ze: "I don't know what Runde Gong has?" ”

Liu Ze said: "I still have some personal relations with Cao Cao, so it is better to repair a letter in Xia and send a messenger to Cao Ying, persuade him to say and quit the army, if he doesn't obey, and then fight with him." ”

Tao Qian shook his head and smiled bitterly: "A certain and Cao Cao have a grudge against their father for murder. How can it be resolved lightly? A few times ago, Cao Cao destroyed the book and beheaded the envoy, but he couldn't do it even if he wanted to, but he was afraid that the public would send people to the past for fear of being harmed. ”

Liu Ze smiled indifferently and said, "I have the same friendship with Cao Cao." The Yellow Turban was recruited to fight Dong Zhuo, and there was always a little thin face in the war. Even if he does not agree to peace, he will not lose his old feelings. If he is willing to retreat, he will save the trouble of swords. ”

Tao Qian nodded yes. Liu Ze wrote a letter back to the barracks. After writing the letter, Liu Ze was about to send a personal guard to send the letter to Cao Cao, Xu Shu said on the side: "Lord, how can you send someone over casually to persuade Cao Cao, it is better to go by his subordinates, and move him with affection and reason, maybe Cao Cao will agree to the lord's peace." After Cao Bing withdrew from the siege, Liu Ze transferred Xu Shu over, but Jia Xu still stayed in Guan Yu's camp.

Liu Ze hesitated, although he said that he had a good relationship with Cao Cao, but the current Cao Cao is not Cao Cao a few years ago, because of the revenge of killing his father, Cao Cao was anxious to red-eyed, seeing people killing people and slaughtering the city, if it weren't for Cao Cao's scorched earth policy, Xuzhou would have fallen long ago, after all, it is impossible for Xuzhou officials to be greedy for life and afraid of death, it is Cao Cao's massacre policy that cut off the idea of surrendering, so he swore to defend the city with Tao Qian.

Sending a small soldier to the past and sending Xu Shu over are completely two different concepts, Xu Shu is his own capable strategist, and there is no room for error.

"Cao Cao is red-eyed at the moment, if he doesn't recognize his six relatives, won't he give Yuan Zhi's life in vain?"

Xu Shu smiled slightly and said: "Don't worry, don't say that the lord still has a friendship with Cao Cao, but with his incorruptible tongue, even if he can't persuade Cao Cao, it is more than enough to protect his own safety." What's more, his subordinates and Cao Cao's adviser Guo Jia had studied in Yingchuan Academy, and they had the friendship of classmates, or they could borrow it. ”

Liu Ze thought about it, this time to envoy Cao Ying, he really needed a person like Xu Shu who could speak well, so he nodded and agreed.

Just as Xu Shu was about to leave, Pan Feng came to report that Zhang Min had been arrested. Liu Ze was overjoyed and asked about the situation in detail.

It turned out that Zhang Min killed Cao Song's entire family, and after intercepting the treasure, he fled to Huainan. Originally, he planned to go to Huainan to join Yuan Shu, but halfway through, he thought that he had worked hard to risk being wanted by Tao Qian and Cao Cao, and once he escaped to Yuan Shu, these treasures were likely to be swallowed by Yuan Shu, and he would not be in vain. It is more likely that Yuan Shu did not dare to offend Cao Cao, and after swallowing the treasure, he gave himself to Cao Cao, so he had to let Cao Cao peel off his skin and tear off his heart. So after thinking about it, he didn't dare to go to Huainan, but switched to his hometown in Runan and went to Jigong Mountain to fall into the grass.

Jin Yingwei has an all-pervasive intelligence network, and soon detectives out Zhang Min's whereabouts. How did Zhang Min's hundreds of soldiers be the opponent of Jin Yingwei, Jin Yingwei dived up the mountain in the middle of the night, and in one fell swoop took out Zhang Min's lair, captured Zhang Min, tied up five flowers, poured them into a sack, and sent them to Xuzhou overnight.

Liu Ze nodded secretly, capturing Zhang Min was equivalent to adding new chips, and it was still very certain to persuade Cao Cao to withdraw his troops. However, Liu Ze has a bigger bargaining chip, that is, Lu Bu will sneak attack Cao Cao's lair, but the only thing that is uncertain is that history does not accurately record the exact time of Lu Bu's sneak attack on Yanzhou, and Liu Ze is not sure whether Cao Cao has now received the news that Lu Bu copied his lair.

According to common sense, Liu Ze, who knew about this historical event, did not need to spend troops at all, he only needed to stay honestly on the tall and sturdy walls of Xuzhou City and wait for Cao Cao to retreat. But in this way, what is Liu Ze's merit in rescuing Xuzhou? With 20,000 horses to Xuzhou to play soy sauce, can you get the support of the people of Xuzhou? Therefore, the top priority is to persuade Cao Cao to retreat as much as possible before Cao Cao gets the news of the sneak attack on Yanzhou, even if he can't sue for peace, he must fight with Cao Cao, but how to grasp this time node is enough for Liu Ze to worry about his nerves.

Xu Shu took a few entourages, escorted Zhang Min, and went straight to Cao Cao's camp.

Cao Cao's camp gate was heavily guarded, with swords and guns, and as soon as Xu Shu approached the camp gate, the guards shouted sharply: "What person? Hold it! ”

Xu Shu said calmly: "A certain is a subordinate of Liu Ze and Liu Taishou of Pingyuan County, and he has come to see Cao Yuanjun. ”

A general flashed out of the camp and shouted: "Duke Cao has an order, all envoys from Xuzhou will be killed!" Come on, take it for me! ”

The soldiers guarding the door immediately stepped forward and prepared to capture Xu Shu, who was surrounded by Jinying guards, not to be outdone, and confronted each other with knives. The general was furious, and he drew his sword and said: "How can this be reasonable, in front of my Cao Ying, I dare to be so rampant, take it for me!" ”

Xu Shu smiled and said: "The two countries are fighting each other, and they don't kill the envoys, is this the hospitality of Cao Envoy?" ”

"Why do two countries not fight each other? Tao Qian killed my Taigong first, Cao Gong has an order, Xuzhou up and down, never leave a living mouth, in order to sacrifice the spirit of Taigong in the sky! If you dare to come to the next book, touch your neck first! ”

At this time, a person came out of the camp, with a crown and a Confucian costume, with a pale face and a thin face, but his eyes were bright and bright, flashing with a wise light, and when he saw Xu Shu, he said in surprise: "Where did Yuan Zhi come from?" ”

Xu Shu smiled and arched his hand: "Brother Fengxiao, don't come to harm?" ”

The general said in surprise: "Guo Junshi, do you know this person?" ”

Guo Jia was Cao Cao's military advisor at this time, and said with a slight smile: "General Zilian, this is my classmate and friend, Yingchuan Xu Shu Xu Yuanzhi." ”

Zilian is Cao Hong's cousin, he saw that Guo Jia and Xu Shu were old friends, so he was no longer embarrassed and let Xu Shu into the camp.

"I heard that Yuan Zhi was directly invested in Liu Runde's account, I don't know what happened here today?" Although he hadn't seen him for many years, Guo Jia obviously knew that Xu Shu had defected to Liu Ze, and it seemed that Cao Cao's secret agents were not eating dry food.

Xu Shu took out Liu Ze's letter and said: "Today, my lord specially ordered Shu to come to reconcile with Cao Gong, this is a letter from my lord to Cao Gong, please Feng Xiao Brother to forward it to Cao Gong." ”

Guo Jia received the letter in his hand and said: "Cao Gong is too angry because of the Taigong's affairs, and his heart is unsettled. With that, Guo Jia gave up his hand and went straight to see Cao Cao.

Cao Cao was losing his temper because of Yu Ban's East Camp for Liu Ze's attack, and was reprimanding Yu Ban and Mao Jue in the big tent, and the two did not dare to speak, and when they saw Guo Jia coming in, they shouted to Mao and the others: "You two retreat, if you are afraid of the battle and slack off the army's morale, you will not be forgiven!" ”

Yu Ban Mao Jue and the two retreated in panic.

"Why is the lord so angry?" Guo Jia said.

Cao Cao's face softened slightly, and he sighed and said: "Yu Ban Mao Ji's thirty or forty thousand horses, but he can't stop Liu Ze's three thousand cavalry, what use do you say you want them?" ”

Guo Jia smiled slightly and said: "The lord is not the usual saying that Liu Ze's cavalry is unparalleled in the world, the Qingzhou soldiers have just been included in the establishment and have not yet been trained, how can they compete with the plain archers who have defeated the wolf cavalry and the Xiliang iron cavalry, and its defeat is also reasonable." If the lord wants to get the strength to compete with it, it must be the tiger and the leopard. ”

The Tiger and Leopard Cavalry is an elite ace unit that Cao Cao has worked hard to build in recent years, which is commanded by Cao Chun as the cavalry governor and formed by the black horse of the party in the state. This is also Cao Cao in the battle of Dong, has a new understanding of cavalry operations, especially after seeing the power of Liu Ze's cavalry new harness, the formation of a strong cavalry has become one of Cao Cao's biggest dreams, he clearly understands that the future cavalry will no longer be an auxiliary army, but will become the main force on the battlefield to be invincible, who has a strong cavalry, who will become the master of the battlefield.
