In a few days under Puyang City, Xu Rong had reorganized the troops and horses. All the wounded soldiers were arranged by him to return to Baima city. With them, there were also the wounded among the 20000 Cao Cao Army prisoners. As for the other Cao Cao Army prisoners, Xu Rong would use them to fill the River and open the siege channel.

As for the guards of Baima city and Baima port, they were also transferred to Puyang City camp, and the soldiers of the two defense departments were handed over to nearly ten thousand wounded soldiers.

In addition to the 20000 troops transferred from the superior Prefecture and the 10000 garrison transferred from the white horse, Xu Rong added all his suitable soldiers to several schools, and all other soldiers were reorganized into several units.

On the 15th, Xu Rong began to arrange for Cao Cao's captives to fill the river and open the siege channel to Puyang City.

At the same time, the five thousand digging soldiers of the Dugu brothers began to work. They began to dig tunnels from a forest five miles north of Puyang City. The five thousand digging soldiers were divided into ten teams by the Dugu brothers. Each team was equipped with five hundred prisoners to transport the excavated soil. At the same time, they dug ten passages into Puyang City.

According to the result of Dugu Xiong's three brothers' negotiation, it takes four to five days to dig all the five tunnels from Wuli outside the city. The most difficult position is the distance between the moat and the city wall. Therefore, Xu Rong is going to take Puyang in five to six days.

Although there is a tunnel in preparation, Xu Rong's attack is still pressing step by step, so that Cao Jun in the city has no time to consider other things.

In the first day, Xu Rong ordered the prisoners of war to reclaim the river regardless of casualties and open the siege channel. In less than one day, Xu Rong filled the moat of Puyang City again at the cost of killing and injuring 2000 prisoners, and prepared nearly 30 siege channels. This is the third time that the moat of Puyang City has been filled in less than a year.

After a night's silence, the next day's attack officially began. Although Xu Rong's attack always seemed so tepid, he was quite prepared for the rhythm of the attack. It was often that the soldiers of the previous round were still on the way to retreat, but the soldiers of the next round had already started.

In the past, several rounds of attacks ended at the end of the day. Although the number of soldiers killed by Cao Cao was limited, the pressure on the city remained.

Not only that, every round of attack does not use ordinary soldiers, but in a certain round of attack, there are dozens of soldiers in the barracks. In this way, Cao Cao's soldiers at the head of the city are miserable. At the end of the day, they dare not relax.

Xu Rong's command once again surprised everyone. At night, in Huangfu's Chaobo camp, the generals were full of confidence in the capture of Puyang.

In Puyang City, however, Cao Cao's army lamented again. Although Cao Cao didn't want to admit it, he knew in his heart that he had been defeated by Xu Rong twice in a row, and if there was no accident, there would be a third.

Cao Cao thought about the morale of the army and his own face, but Xia Houdun didn't think so much about it. Cao Cao couldn't do some things, but he had to do them.

In Puyang City, in the county government, Cao Cao was also gathering the generals for discussion. When Cao Cao finished speaking, Xia Houdun got up and said, "general, in my opinion, we must consider withdrawing our troops. Our army was defeated and demoralized. Less than 20000 of the 50000 troops fled back to the city, and there were only more than 20000 of the 5000 garrisons in the city. The sergeant of Sizhou outside the city came to attack with the threat of victory. Judging from today's war, Xu Rong is not an easy man to fight with. Instead of fighting with Sizhou army in Puyang City, he might as well lead these 20000 elite soldiers to break through, preserve their strength, and get there Then we will fight with the SZU army. "

"Yes, Lord, this is the elite after the real war. With them, we can successfully train more powerful soldiers." Yue Jin said on one side;

"Puyang City is solid, and the Sizhou army has begun to attack the city. How can we give up so easily? We are not as good as Sizhou army in field combat. Can't we defend according to the city?" Cao ang retorted immediately;

Cao Anmin also stood up: "yes, even if we want to retreat, we have to tear a few pieces of meat from Huangfu Chaobo, otherwise we will come back in vain."

Several veteran generals are quite cautious, especially Xia Houdun. Together with Cao Cao, he suffered losses in Xu Rong's hands several times. A few years ago, Cao Cao almost fell into his hands, and Huangfu Chaobo rescued him. Now, a few years later, he did not expect that Xu Rong would become a subordinate of Huangfu Chaobo.

When he saw Xu Rongzhi outside the white horse city, Xia Houdun still had the idea of revenge. But a few days ago, a big war once again brought him back to reality, and Xu Rongyi hit him so hard that he could hardly fight back.

In today's war, Xia Houdun obviously felt that Xu Rong didn't do his best, but he still let his army have some left and right branches. So when it came to the discussion in the evening, he didn't hesitate to break through.

In his view, there were only 15000 elite soldiers left in the 50000 army, and the remaining nearly 10000 soldiers served as a cover for the army to break through the encirclement. With these 15, 000 elites for the rest of the world war, it will only take a few months to replenish them.

But the two young generals are still unconvinced. Although their army has failed in the field battle, can't they defend the city?According to Cao Cao's heart, in fact, he also wanted to lead the troops to retreat immediately. But facing his eldest son and nephew, Cao Cao didn't want to admit defeat so easily. You know, this is their first battle. If the army breaks through the encirclement before it is defeated, it will be very disadvantageous for their future leadership.

Thinking of this, Cao Cao looked at the two military advisers beside him. Sima Yi was too young. Seeing that Cao Cao looked at him, he immediately proposed that he should not give up easily.

Cheng Yu, however, stroked Hu and said nothing. Seeing Cao Cao Chao, he didn't answer immediately. Instead, he stood in front of the map and said nothing.

After a long time, Cheng Yu asked Cao Cao, "has the Lord ever heard from Cao Hong?"

Cao Cao was stunned and said, "Zi Lian sent someone to send news the day before yesterday that he has captured yongqiu. According to his itinerary, he should arrive at the foot of Chen Liucheng today. Zhong De's intention is that

"Yes, since we have to leave sooner or later, we just need to ensure the combat power of the most elite soldiers. The longer we delay, the longer we can fight for general Zilian."

"That's right," said Xia Houdun, clapping his hands. "It's Mr. Cheng. Since we can't keep Puyang, we'd better fight for more time for Zilian."
