Seeing that the main general was in high spirits and regarded death as home, the panicked Cao Jun was greatly encouraged, and finally calmed down, clenched his weapon, and followed Xiahou Yuan to prepare for a bloody battle with the enemy.

Cao's army is the elite, and the 10,000 horses led by Zhao Yun are also not weak, but they are the men and horses when Liu Yong conquered Changsha, and later after entering Xiangyang, he was worried about the instability of Jiangling and transferred to Jiangling to prepare for the unforeseen army.

When the two armies met, the stumps immediately flew around, blood splattered, Cao's army was demoralized, and the killed kept retreating.

Xiahou Yuan was a general under Cao Cao, extremely brave, the moon slashing knife in his hand flew up and down, and the Jingzhou sergeants were killed one after another, and no one could stop him.

But after all, Cao's army was truncated into two sections, just now was stoned to death and wounded five or six hundred people, and was shot by a rain of arrows, trampled on each other and killed and injured seven or eight hundred, and now there are only more than 1,000 people left here, and under the disadvantage of the number and low morale, the killed are losing and retreating.

Xiahou Yuan slashed dozens of people in a row, covered in blood, seeing that the defeat was decided, even if he himself was extremely brave, but his two fists were invincible to four hands, and in the end, even if he died in battle, it was difficult to recover the defeat.

"Climb over the mountains and retreat to the West City!" Xiahou Yuan couldn't care about his grief anymore, and ordered angrily.

A thousand Cao troops broke through the encirclement and walked over the mountains under Xiahou Yuan's moon slashing knife, but lost more than 300 people again.

Du Xun led people to chase and kill all the way through a mountain before returning to the military pass.

Zhao Yun originally wanted to ambush Xiahou Yuan in person, but he was afraid that Wuguan would be lost, so he didn't dare to leave without permission, knowing that Du Raid would be difficult to leave Xiahou Yuan behind, he was still helpless.

After praising Du Xian, Zhao Yun immediately wrote two secret letters and handed them over to his confidants in Xiangyang and Zang Ba Daying.

Three days later, after getting the report of Zhao Yun's battle, Liu Yong was overjoyed, and at the same time got the report that Yu Ban had returned to Xuchang, and the rebel general Wen Ping also led 5,000 men and horses from Pingyu to Linying, Liu Yong decisively ordered Guan Ping to withdraw to Kunyang.

Hefei City.

At this moment, it is close to the Mid-Autumn Festival, and nearly a month has passed since it was surrounded by the Jiangdong army. Zhou Yu's plan to "exterminate grain" did not play a decisive role as previously expected. Although the food in Hefei City was consumed a lot by these tens of thousands of rats, because Zhang Liao and others organized the military and civilians of the city in time to carry out rodent extermination, most of the rats were extinguished in time, and the remaining food was still enough for the people of the city to support for half a year. It seems that Cao Jun in Hefei has successfully escaped the catastrophe again.

But just when Zhang Liao and the others were just relieved and planned to laugh at Zhou Yu's absurd tricks, the real catastrophe followed. In the summer and autumn, the vegetation was rotting, and it was the time when the plague was frequent, and although the rats in the city were extinguished, the corpses of dead rats were everywhere, and the plague soon began to break out in the city.

Zhou Yu calculated very accurately, he was waiting for this moment. After discovering that the plague was beginning to occur in the city, Zhou Yu decisively took advantage of the last wave of precipitation in autumn to dig up the water and flood the city of Hefei.

At that time, Liu Fu built Hefei City to be extremely strong, and the location of the city was not a low-lying area, although Zhou Yu sent people to dig up the water, but it was not enough to wash away the city, the city water was waterlogged, but it was just not to the foot surface.

In normal times, this method of digging water to flood Hefei would not have played a crucial role at all, but at such a moment of plague outbreak in the city, the effect is fatal.

The carcasses of rats carrying the plague were soaked in dirty water and quickly spread to the whole city, and the drinking water in the city was soon completely polluted, and once the water was contaminated, the plague naturally spread rapidly. In just half a month, thirty percent of the soldiers and civilians in the city were infected with various epidemics, and the heavy ones died after not being able to support them for a few days, and the light ones vomited and leaked. In January, the city of Hefei has become a plague-ridden dead city.

This is Zhou Yu's plan.

As long as he can break through this important military town leading to the north, even if he kills all the people in the city, all he gets is an empty city, and Zhou Yu will not hesitate to do it.

When the people and defenders of Hefei City were suffering from purgatory, in Shouchun, Xu Chu was still working overtime to build the Shaobi Dam. Because the last wave of precipitation in autumn was more violent than in previous years, and the flood swelled and broke the originally repaired embankments in several places, the date of Xu Chu's army coming south to Hefei had to be postponed.

Just when Cao Cao ordered Xu Chu to rush to work day and night to repair the embankment, the news from Hefei was getting worse and worse every time. The latest emergency report was sent by Xue Yi, the supervising army, saying that Zhang Liao and Le Jin were both infected with illness and could not see things, and the defenders in the city had become trapped by illness and basically lost their combat effectiveness, and Hefei City was already in danger.

The snowflakes like a distress report made Cao Cao's mood heavier, he really didn't expect Zhou Yu to be so ruthless, in order to get Hefei City, he did not hesitate to use such vicious methods. The situation was far worse than Cao Cao had expected, and the illness of Zhang and Le made him realize that he was afraid that Hefei would not be able to wait for the moment when his side repaired the embankment and the army rushed to the rescue.

After further weighing, Cao Cao had to make a difficult decision, ordering Zhang Liao and Le Jin to abandon the city and break through to retreat to Shou.

Zhou Yu, who was besieging the city, seemed to have calculated that Cao Cao would make this decision, so not long ago, he ordered the siege of the north of the city to be withdrawn, and took the initiative to give up a mouth to the enemy. A few days later, Xue Yi in the city received a secret order from Cao Cao, which made everyone breathe a sigh of relief.

That night, Xue Yi took the sick and weak General Zhang Le, led 2,000 troops who were still capable of fighting, and quietly went out of the north gate under the cover of night, and walked by land to Shou inside and outside. At dawn the next day, when the remaining military officials in the city learned that the main generals, assassins and other high-ranking officials had abandoned the city, they decisively opened the city gate and surrendered to Zhou Yu.

After besieging the city for more than two months, Zhou Yu finally planted his banner at the head of Hefei.

The residents of Hefei City are basically infected by the epidemic, and Zhou Yu has long been prepared for how to deal with the people suffering from the plague.

He first ordered that another isolation camp be set up ten miles outside the city, and that those civilians who had not been infected with the disease should be moved to the isolation camp to prevent them from spreading to the outside world. For those civilians who had contracted the disease, Zhou Yu allocated them several days' rations, and gave them some old, obsolete boats, and drove them north along the river to the Cao Zhan area on their own.

Zhou Yu's move is another ruthless move, which clearly has the meaning of chasing trouble and going north. These tens of thousands of infected people, once they go north to the Shouchun line and enter the densely populated Central Plains, will inevitably cause considerable panic, and once the epidemic they carry spreads, the consequences will be very serious. And these people are the people under Cao Cao's rule, if you Cao Cao don't save them when they die, and refuse to accept them, you will definitely lose people's hearts. If you take in these epidemic people, but you don't handle them well, causing the epidemic to spread in the Huaibei area, it will also cause resentment.

No matter how Cao Cao responds, in the face of Zhou Yu's ruthless move, he will always have to pay the price.

"Whatever you want!" Zhou Yu stood at the head of Hefei City and laughed.
