Facing the current situation in Puyang City, Cao Cao was really a little worried, and he felt that he was only afraid that he was in a desperate situation.

Maybe Cao Cao still has a way, that is, surrender, but Cao Cao is naturally unwilling, and besides, many relatives of the Cao family and the Xiahou family have died in the war with Zhu Weijun, Cao Cao really can't let go of all this and bow down to Zhu Wei.

In desperation, Cao Cao could only choose to continue to defend Puyang City.

For this reason, in the area of the city wall where the Zhu Weijun piled up the earth, Cao Cao originally asked people to construct a defensive wall on the city wall, so that after the Zhu Weijun rushed up the city wall, they could not directly kill everywhere on the city wall, while Cao's army could resist the attack of the Zhu Weijun behind the wall.

However, the ramparts that were built on the city wall were soon smashed by the rocks thrown up by Zhu Weijun's thunderbolt catapults.

Then Cao Cao asked people to construct layers of defensive lines in the city, even if Zhu Weijun broke through the city wall, he was also ready to continue to fight with Zhu Weijun in the city, continue to resist and delay Zhu Weijun's time, and consume Zhu Weijun's grain and grass.

Now for Cao Cao, only by delaying time, only by making Zhu Wei's food and grass insufficient, can he force Zhu Wei back and let him survive in Puyang City.

In this way, as time passed day by day, nearly half a month passed, and the mound ramp that Zhu Weijun piled up outside the eastern city wall of Puyang City was about the same height as the city wall of Puyang City.

So on a crisp autumn day at the end of September, Zhu Wei's general attack on Puyang City was also launched.

Zhu Weijun gave up harassing attacks on the other three parts of Puyang City, leaving only some of the troops still guarding the besieged camp to prevent Cao Cao from breaking through and escaping.

Then Zhu Wei placed all the siege equipment outside the east city of Puyang City, and at least twenty thunderbolt stone throwers continued to throw stones at the city wall.

Then at least forty or fifty mobile arrow towers were erected outside the city, and nearly a thousand archers shot feathered arrows at the city wall from the high platform of the arrow tower to suppress the defensive actions of the Cao army defenders on the city wall.

It can be said that under the suppression of Zhu Weijun's throwing stones and feather arrows, there is almost no area on the front city wall where Cao's soldiers can stand safely.

In this way, under the urging of the earth-shattering war drums in Zhu Weijun's main formation, Huang Zhong's Huainan battalion obtained the first task of attacking the city, so Huang Zhong personally led the elite of the 8,000 Huainan battalion to rush to Puyang City along the mound ramp.

With the efforts of Zhu Weijun for nearly half a month, the slope of the mound leading directly to the head of the Puyang city wall and the ground is about 120 degrees, and the ramp from the top of the mound at the head of the wall to the ground at the bottom is about 300 steps.

And the entire ramp is at least more than 100 steps wide, which means that there can be seventy or eighty soldiers who can charge the city wall side by side, but in a few breaths, they can rush to the city wall.

At the same time, it was enough for four or five thousand soldiers to attack on the city wall, so Huang Zhong's Huainan battalion of eight thousand siege troops was divided into two batches, which formed a dense shield array, and steadily charged up along the mound ramp towards the east wall of Puyang City.

Huang Zhong and Chen Ji, the general of the Huainan battalion, also hid in the first batch of shield arrays.

They would follow the first group of soldiers to rush up the city wall, and use their martial arts to break through Cao's defenses, thus opening the way for the follow-up soldiers to come immediately.

As the commander of the Huainan battalion, Lu Su, who is now also wearing clothes and armor, is hiding in the second batch of shield arrays, and he will be responsible for commanding the follow-up Huainan battalion soldiers to go up in time to support Huang Zhong.

When they charged, the thunderbolt stone throwing cart and the archers on the moving arrow tower were still throwing stones and shooting feather arrows, suppressing the movements of the Cao soldiers on the city wall, especially in the area of the city wall connected by the dirt slope, which made the Cao soldiers dare not approach at all.

With the rumbling of war drums in Zhu Wei's army, although Cao Jun knew that Zhu Wei's army was attacking the city, they were helpless.

At this time, a large number of Cao troops gathered in the inner side of Puyang East City, in the area where the Thunderbolt Catapult could not attack, it was also ready to go up to meet the upper city wall of Zhu Wei's army at any time, as long as Zhu Weijun went up to the city wall, then Zhu Weijun's Thunderbolt Catapult would also stop throwing stones, and then it would be the moment when the war really began.

In the face of the stones thrown in the air, it is really not something that human power can compete with, and now even if they go up, they will die as many as they want.

At this moment, Cao Cao and a group of civil and military generals also stood on a high platform built in the city, watching the battle on the city wall in front, and under the city wall was also full of Cao Jun's soldiers and generals, who would follow the instructions at any time to go up and fight with Zhu Weijun on the city wall.

"Knock... Knock..., knock... Boom! ”

The war drums and trumpets in Zhu Wei's army soon underwent some changes, so the thunderbolt stone-throwing cart that had been constantly throwing rocks finally stopped, and the battlefield seemed to be a little calmer suddenly.

But soon in front of the city wall of Puyang City, the Zhu Wei army, who had already reached the edge of the city wall, suddenly let out a burst of shouts and killing, and then the first wave of 4,000 Zhu Wei soldiers bravely went to the city wall to kill.

Although the city wall here is full of rocks thrown by stone-throwing trucks, and the ground is mostly full of potholes made by rocks, no one cares about this at this time.

The soldiers of Zhu Wei who killed the city wall quickly divided into two military formations, and rushed along the city wall to both sides, as if they were preparing to take the outer city defense of Puyang City along the city wall first.

Of course, the Cao army, which had already prepared to meet the attack, also rushed towards the location of Zhu Weijun, and on the city wall about fifty paces wide, the soldiers of the two sides finally fought together.

The battlefield on the city wall is not very wide, and those who can fight at the same time are only dozens of soldiers at the forefront, which can be said to be the battle between the two armies at the forefront.

At this time, the Cao army was naturally the elite of the soldiers, so at the initial moment, the two sides seemed evenly matched, and the soldiers of the two armies were all building a shield array, almost only colliding and squeezing each other, competing for strength.

Even if a soldier stabs a ring-headed knife from behind his shield, it will often be blocked by the opponent's shield, or slashed at the soldier, blocked by the thick iron-inlaid armor, unable to deal any damage.

However, Zhu Weijun's side seemed to have expected this possibility, so just as the front was at a stalemate, two soldiers in the rear suddenly took out a fist-sized black iron ball from the cloth bag on their backs.

The surface of this iron ball seemed to be full of cracks, more like a lot of broken iron pieces were inserted into the loess inside, and they didn't know what was formed by the gum, and then they took out a small bamboo tube and inserted it into a place, as if it had penetrated into the core of the iron ball.

Soon they lit the fuse in the small bamboo tube with a fire breaker, and seeing that the spark quickly entered the small bamboo tube along the fuse, and then burned into the core of the iron ball, the two soldiers threw the iron ball into the Cao army array in front......
