Since the fire in the black nest, the spies of the black nest have informed Sima Yi with a flying pigeon.Sima Yi also knew roughly about the battle situation in Wuchao's grain storage land, and he also made an estimate of every move.If Zheng Feng goes to Fengqiu, after setting the fire, he can completely ignore Yuan Shao's reinforcements and retreat directly from the land of grain to Fengqiu.However, after Zheng Feng set the fire, he went to guard Wuchengchi, which showed that Zheng Feng was already vigilant, and most likely would not go to the dangerous place of Fengqiu.So, he made a quick decision, no longer waited for the rabbit, gave up the sealing of the hill, led the troops to take the path, and rushed to Yecheng.He expected that Cao Cao would not be able to escape from Zheng Feng's palm, so he made a desperate bet to occupy Yecheng before Yuan Shao retreated to Yecheng, intercepted Yuan Shao's back road, and forced Yuan Shao to surrender to him.As long as he gets Yuan Shao's soldiers and horses, he can do a great job, the south can swallow Cao Cao's forces, the north can occupy Yuan Shao's territory, and he can immediately become a powerful overlord.He also informed his eldest son Sima Shi, who stayed in Yanzhou, to draw 5,000 troops from Yanzhou to support, and also instructed Sima Shi to pull Zhuang Ding everywhere to replenish his troops as soon as possible.The news of the fall of Wuchao soon spread to Yecheng, and the guard general Gao Gan was shocked, knowing that Cao Cao must take the opportunity to chase and kill, and the grain and grass of Yecheng were almost transported to Wuchao, and there was no food that could not be guarded for a long time, and Yecheng would be Cao Cao's dish sooner or later.Yuan Shao's general trend has gone, sooner or later he will be annexed by Cao Cao, Gao Gan immediately planned for the future, he took advantage of Yuan Shao's death, occupy a piece of land as king.Yuan Shao went south to fight Cao Cao, leaving his three sons in the north, each of whom guarded a prefecture.Yuan Tan stayed in Qingzhou, Yuan Shang guarded the base camp in Jizhou, and Yuan Xi occupied Youzhou.There is also a sore Beiping, Gongsun Zhan took advantage of Yuan Shao's southward movement to capture Beiping and return to his original home.Gao Gan eliminated these territories one by one, because he only had more than 30,000 troops at his disposal, and he did not have the strength to compete with these people.In the end, Gao Gan locked his eyes on the merger, where there was only one Gao Xiang guarding the town, and Gao Xiang was his relative, and he must be able to give up the merger.Gao Gan immediately sent his family members away first, and let the 20,000 main troops escort them along the road and go straight to the state.When Sima Yi rushed to Yecheng by taking the path, Gao Gan was shocked, he didn't expect Cao Jun to come so quickly, and he didn't have many troops on hand, it seemed that Yuan Shao would even have difficulty retreating to Jizhou.As for Yecheng, it doesn't matter if the senior cadres do, now this city is just Yuan Shao's retreat, so he won't fight hard for it.Gao Gan took advantage of Sima Yi's failure to start attacking the city, so he quietly led all the horses to retreat from the north gate and surrendered Yecheng.Sima Yi was overjoyed and obtained Yecheng without spending a single soldier, which surprised him and made his ambitions even more ambitious.As soon as the 5,000 reinforcements from Yanzhou arrived, he had more than 20,000 elite soldiers to defend Yecheng, and Yuan Shao was dead.The high walls of Yecheng City are thick, and on the side facing the retreat of Guandu, there are two peaks as natural hazards, and no matter how many soldiers and horses Yuan Shao has, he will not be able to fight into it.Sure enough, Yuan Shao retreated here, and now that Yecheng had been lost, he couldn't help but panic.Although Yuan Shao was defeated and retreated, he still had an army of 150,000, and his strength should not be underestimated.Yan Liang and Wen Chou each led 50,000 troops to attack the city, and after two days of fighting, they could not attack Yecheng.The situation was unfavorable to Yuan Shaoyue, the military rations had run out, the soldiers were not full, they began to complain, and deserters began to appear.Sima Yi calculated that Yuan Shao's grain and grass were about to run out, so he sent an envoy out of the city to negotiate, demanding that Yuan Shao surrender to him, and he promised to give Yuan Shao a Qingzhou to live in, and he would be prosperous and wealthy for a lifetime.Yuan Shao saw that there was no hope of returning to Jizhou, and now that the grain and grass were exhausted, the whole army was undoubtedly annihilated, except for waiting for death, the other way was to surrender.But he was not too reluctant to surrender, Sima Yi was just Cao Cao's military advisor, Yanzhou was too guarded, and it would be too embarrassing to surrender to Sima Yi.After hesitating, another soldier hurriedly reported: "Cao Cao led tens of thousands of troops to chase after him, please prepare for the lord." ”Yan Liang, Wen Chou and others were shocked, Cao Cao chased after him this time, he must be killed, and now the soldiers have no fighting spirit, all waiting to surrender, why should they fight with Cao Cao Yuan Shao laughed: "Cao Cao is good, I would rather surrender to Cao Cao than to surrender to a small Yanzhou guard." ”Yan Liang and others also thought that Yuan Shao's idea was good, and it was much better to surrender to Cao Cao than to Sima Yi.So, Yuan Shao ordered the troops to surrender in formation, and he personally raised the white flag to greet Cao Cao.Cao Cao was naturally overjoyed, Yuan Shao still had more than 100,000 soldiers under him, as well as Yan Liang and Wen Chou, two fierce generals, if he got this army, he could immediately wave his army south, attack Wancheng, and occupy Jingzhou, which is not a problem.Cao Cao entertained Yuan Shao's surrender with a high standard, and also called Yuan Shao a brother, in order to buy the military heart of the surrendered soldiers, he promised to give Yuan Shao a lifetime of glory and wealth in front of more than 100,000 surrendered soldiers, and immediately promised to return to the court, and must give Yuan Shao a higher official position.Yuan Shao whispered to Cao Cao: "Sima Yi just sent someone to persuade me to surrender and promised to make me the Taishou of Qingzhou." ”Cao Cao was furious: "What kind of person is Sima Yi, he dares to canonize his official position privately, and I will be him when I turn back." ”Angry to angry, Cao Cao, in order to appease Yuan Shao, simply sealed Yuan Shao as the Taishou of Qingzhou and let Yuan Shao go there to retire.Cao Cao's abacus is jingling, if he wants to unify the north as soon as possible, and Yuan Shao still has power in the north, his three sons occupy Youzhou, Jizhou and Qingzhou respectively.As long as Yuan Shao accepted the Qingzhou Taishou, Yuan Tan, who was stationed in Qingzhou, would be abolished, and the other two sons would also have to return to Shun sooner or later, and the north could be unified.Yuan Shao suffered such a fiasco, and Cao Cao did not kill him or imprison him, which was a great blessing.Now, give him a Qingzhou pension, although he can no longer compete for the world, but still continue to live a life of wealth and wealth, he has already laughed out of his eyes, Yuan Shao immediately knelt down, accepted the post of Qingzhou Taishou, and rushed to Qingzhou.Yuan Shao swore an oath to Cao Cao again and immediately repaired the book to his three sons so that they could join Cao Cao.Cao Cao was overjoyed and ordered Che Zhou and Lü Qian to lead 10,000 soldiers and horses to escort Yuan Shao to Qingzhou to take office, and stay in Qingzhou to assist Yuan Shao.Later, Cao Cao secretly instructed Che Xuan and Lu Qian to closely monitor Yuan Shao, if Yuan Shao had the intention of rebellion, Cao Cao first beheaded and then played Cao Cao and ordered his subordinates to take out the military rations and put them to the surrendered soldiers, so that after they could eat, they would prepare to attack Sima Yi.Xu You hurriedly dissuaded: "Although Sima Yi is ambitious, he rebelled because he knew that his lord was taken captive.Now that the lord has returned, he will not dare to make a mistake, and the lord will not be able to cure his crimes. ”Cao Cao said angrily: "Fortunately, I came in time, otherwise Yuan Shao surrendered to Sima Yi, Sima Yi got Yuan Shao's army, he dared to rebel openly, I will die without a place to be buried, how can I spare him" Xu You persuaded again: "The lord is currently the time to employ people, Sima Yi belongs to the top military division, can fight well, and punish him, the lord is equivalent to losing an arm." ”:
