Therefore, Cao Cao also arranged to strengthen the defense of the city overnight. First of all, he arranged 1000 soldiers in several suspicious places, plus the assistance of 1000 soldiers from prefectures. However, Cao Cao himself must have found no tunnel, so he specially arranged 1000 tiger and leopard cavalry and 1000 Qingzhou soldiers around the four city gates, and 1000 tiger and leopard cavalry and 1000 Qingzhou soldiers to patrol around the city. Once he found any abnormality, he could control the situation as quickly as possible.

In this way, 15000 of Cao Cao's most elite Qingzhou soldiers and tiger and leopard riders have been dispersed. Since the eastern army will attack the city with all its strength, the defense at the head of the city must be strengthened, so another 15000 Qingzhou soldiers have been arranged on the East, South and west walls to assist in defense. Cao Cao himself has only 5000 Qingzhou soldiers and 5000 tiger and leopard riders Riding as the last mobile force.

There was nothing to say all night, and both sides were making final preparations.

A new day has finally arrived. At dawn, the camp of the eastern army is noisy again. All the breakfast prepared in advance has been ready. Not only that, the cooks have also prepared some dry food for all the taxi drivers to take with them. Seeing these things, everyone knows that today's war must not be as simple as usual.

After all the taxi drivers had breakfast in silence, they quickly sorted out their weapons, and then went out of the barracks one by one, quietly waiting for the order of the army to start.

When all the soldiers and horses were ready for the battle, the bugle "Wuwu" of the Chinese Army's big tent sounded, and the bleak bugle reverberated on the field for a long time, and then the armies, led by the generals, slowly approached the direction of Changyi city.

When the first ray of sunshine appeared in the morning, more than 100000 soldiers of Zhengdong had orderly appeared under Changyi city. In the morning mist, red squares loomed in the white haze, silent. In the air, there was only the "Hua Hua" sound of the morning breeze blowing over the flag, and occasionally the snoring sound of the horses Swing.

On the nest car of the Chinese army, Huangfu Chaobo slowly pulled out his sword from his waist with his right hand and waved it forward fiercely. He yelled: "attack!"

Then, the messenger on the nest car raised his flag and waved it toward the front. At the same time, he yelled: "general, you have orders! Attack

"Dong Dong Dong"

In an instant, the biggest drum of the Chinese army was knocked by the drummer, followed by dozens of drums, followed by hundreds of drums of the Western army, followed by the attack.

However, in a few minutes, the battle drums and bugles in the South also sounded one after another, and then spread to the East. For a time, the trumpets and drums of the eastern army outside Changyi echoed over the whole city for a long time.

As early as when the first drum sounded outside the city, the alarm bell on the tower was also quickly sounded. The "Dangdang" alarm bell quickly spread all around the city walls, and Cao Cao Jun in the city quickly ran to the city walls to prepare for the battle.

On top of the Chinese Army's nest car, Huangfu Chaobo looked at the soldiers marching on the drum to attack the city wall without saying a word. The first wave of attack soldiers made adjustments at the last moment. Considering that although the tunnel has basically arrived in the city, it will take some time for it to get through, so the first wave of attack soldiers were replaced by guards, and they will be soldiers For the first wave to attack the city wall, but also for the follow-up troops consumed most of the garrison materials.

When the first bosh soldiers approached the city wall, all the siege equipment of the eastern army were pouring desperately towards the city. Hundreds of stone catapults were constantly firing stone bullets towards the city, suppressing the attack of the city soldiers. Hundreds of well fences are also rapidly approaching the city. On the well fence, thousands of archers and crossbowmen, after reaching their own attack range, will shoot their arrows towards the city. The arrows like clouds are flying towards the city.

Among all the siege battles, Xiandeng is always the one with the biggest casualties. When the first wave of soldiers began to ascend the city, Huangfu Chaobo's order was issued again. The second wave of attack troops, which had already been prepared, quickly set out and approached the city wall. At this time, the war has begun for nearly a quarter of an hour, and the war in Chengtou has become white hot.

At this time, thousands of people were working frantically under the wall of Changyi city. The pickaxes in their hands were working hard to dig in front of them. The excavated soil was directly put into the cloth bags, and then the civilians handed out the tunnels one by one. By this time, the garrison in the city had already found out.

In Changyi City, the sergeant Cao Cao, who is responsible for listening, is still concentrating on monitoring the underground movement. Unfortunately, the huge roar outside the city and the blade impact sound of the sergeant Cao Cao's fighting at the top of the city have made it difficult for him to hear any movement. Even so, the taxi driver in the urn still sticks his ears tightly to the wall of the urn and listens carefully.

Suddenly, the soldiers suddenly got up and reported to the general on the ground: "general, they are coming!"

This is one of the five tunnel excavation sites discovered in recent days. Within hundreds of steps around this place, there are already two thousand Cao Cao soldiers waiting for them.The words of sergeant Weng made all the soldiers around cheer up. They held their weapons tightly in their hands and stared at the ground. They seemed to want their eyes to go directly through the ground to the tunnel dug by the Zhengdong army. Unfortunately, all this was in vain. Their eyes were sore and they didn't see any abnormality from the ground.

The leader nodded at the soldier in the urn and said, "are you sure of their direction?"

"Not yet, but their voices are much louder and clearer than those of the previous two days. It seems that they are digging quickly." With that, the soldier squatted down again and listened carefully.

Seeing this, the soldiers nearby all breathed and held their breath, trying not to make any noise, so as not to affect the soldiers in the urn.

A quarter of an hour later, the sergeant of the urn stood up again and whispered to the captain: "general, they are approaching. Their voice is getting louder and louder. They are more than ten steps away from the urn at most."

With that, the soldier pointed in the direction of the sound, and then he went up to the wall of the urn again and listened carefully.

Seeing this, the leader quickly directed the soldiers to gently surround them in the direction they pointed out, and surrounded all the distance of dozens of steps around the corner. All the people held their weapons tightly, waiting for the soldiers to break the ground.
