As a matter of fact, once this digging Army knows about it, it's just like that. As long as it's on guard, it's easy to crack it. That is to say, we should send soldiers to dig some big pits behind the city wall, and then put some big tanks in the pits, and send soldiers to listen carefully inside. But the problem is that Cao Cao Jun didn't know which princes in the world (in the game) used this method to attack the city before, so it's normal for Cao Cao Jun to suffer losses.

As soon as Ren Jun's words were finished, Sima Yi immediately responded and said, "Lord, you must immediately find a way to inform general Cao Hong of Qiao County. The lower officials suspect that Huang Zhongjun will also use this method in Qiao County."

Cao Cao suddenly woke up, immediately turned his head to look at his son Cao ang and said, "hurry up, send someone to rush to Qiao County, let them find a way to get into the city, we must inform Zi Lian. In addition, Wen Ruo, who sent an order to Changyi, asked him to write a letter to all the city's generals and officials. In the future, before defending the city, we must guard against this kind of attack. I always feel that among the vassals in the world, it should not be the only way to do this is to recruit the eastern army. "

Cao ang immediately sent someone to do it, and then Cao Cao ordered: "send the army to turn around, return to Changyi, and be ready to defend the East army. If we lose Shanyang again, Yanzhou will have no place for us."

Tens of thousands of troops turned from the former to the latter and returned to Changyi. Although this was a big blow to the morale of the army, they could not care so much at this time. In Dingtao City, there are no more than 30000 troops. These 50000 troops are the last elite army that Cao Cao can bring out. If the East army doesn't care and catches up, it will be more or less dangerous.

As a matter of fact, Huangfu Chaobo also thought that after he conquered Dingtao, he would march South nonstop. But now Cao Cao's army is more than 30 miles away from Jiyin, and only 50 or 60 miles away from Changyi. After nearly 10 days of fighting, his army is far from exhausted, but it has also lost more than 20000 troops. Cao Cao Cao's army is only one day's March In contrast, although they are superior in military strength, they do not have much advantage.

So instead of taking risks, it's better to fight steadily and make progress step by step. In any case, Huangfu Chaobo no longer had the luxury of solving Cao Cao in one year.

The news of Cao Cao's army's withdrawal to Changyi soon spread back to Dingtao city. Huangfu Chaobo didn't care about it, but just gave a faint smile. He had already discussed with pangtong about the next step, that is, to take full control of Jiyin county and Liang County, then wait for the end of Qiao County's war, and then force peiguo, Shanyang and Dongjun. At present, it's very difficult It's pressure to protect Cao Cao Jun.

In fact, another reason for this is that if we really march all the way, the supply line of the army will be too long. If we are not careful, the war will be defeated and the gains will not be worth the losses.

When he got the news of Cao Cao's retreat, Huangfu Chaobo was gathering the generals to discuss the next step of troop deployment.

"Ladies and gentlemen, after Suiyang, the state of Liang, the second county and city of Cao Cao Jun is under our control. Congratulations Huangfu Chaobo smiles to all the people in the hall;

"Congratulations, Lord!" All the people congratulated together;

"this is the result of the concerted efforts of all the officers and men, but the war is far from over, and there are still more wars waiting for the army in the future. I hope the army will continue to work hard."

"We will live up to the trust of our Lord!"

"Just one thing, that is, Dugu Ba and Dugu Tian, the two captains of Dingtao City, have made great contributions to the capture of Dingtao city so easily. However, the biggest Assassin's mace of our eastern army's attack has also been exposed to the world. It is impossible for the future war to be so easy, so you should be prepared for it."

Zhang Ying said: "don't worry, my Lord. I've never been afraid of anyone when I'm fighting in the East."

"OK, OK, general Zhang, that's a magnificent remark!" On one side, Dianwei listened to Zhang Ying's words and burst out laughing.

The rest of the generals also nodded in agreement. Huangfu Chaobo was also very happy to see that his subordinates were so confident. However, he still wanted to remind us: "if we talk about a strong general, I am not afraid of the world's princes, but we can't underestimate the world's heroes. This time, Cao Cao will give us a wake-up call. What's more, the defense of Ren Jun, the governor of Jiyin, is also very good. If we don't have a tunnel to help us, it will be difficult for us to capture this city in one or two months

Everyone nodded thoughtfully. It's true. Although Ren Jun lost his city and fled in a panic, he did a very good job in defense. It can be said that if only on defense, he would be ranked in the top 20 in the East army.

Seeing that all the generals seemed to have realized something, Huangfu Chaobo no longer said much and turned to Pang Tong.

Pang Tong understood and stood up and said, "you guys, after discussing with the Lord, we decided to slow down the attack for the time being. That is to say, we should ignore the main force of Cao Cao's army in Shanyang first, and then we should take full control of Jiyin and Liang. When the time is ripe, we should send troops to Shanyang."

With that, he quickly walked up to the map and pointed to it to explain in detail the arrangements for the later stage of the war.

After another day's rest in Dingtao, the army will begin to divide one into three parts tomorrow. One will be led by Zhang Ying, who will lead 15000 soldiers, 10000 guards and 5000 people in the army, plus 3000 captured by Cao Cao's army. They will attack north and capture the cities of Jiyin north of Dingtao.Huang Wudi led his 15000 troops and the same number of guards, civil servants and prisoners to attack the south. He captured the cities of Chengwu and Danfu. After he captured the cities of Jiyin, he continued to move southward and captured all the cities of the state of Liang.

In this way, it will basically take more than a month. By that time, Huang Zhong's two armies should have occupied the cities of Qiaojun. By then, they will send troops to peiguoshanyang. If Cao Cao's forces can be suppressed in Xuzhou, Qingzhou and the east of Yanzhou within this year, it will have reached the expectation of Huangfu Chaobo.

Two army leaders went out to fight, and Huangfu Chaobo led the guards to defend Dingtao, staring at the elite movements of Cao Cao's army in Changyi.

When Huangfu Chaobo began to arrange the troops to attack on both sides, the war in Qingzhou became more and more fierce. Cao Cao made a single bet and almost transferred all the elite soldiers from the counties in the east of Yanzhou and Qingzhou. Now almost all of these counties are newly recruited soldiers. In a few days, under the county seat, Cao Cao's reinforcements arrived almost every day, which increased the pressure on the soldiers in the county, and the war between the two sides became increasingly fierce.
