After all, the process of standardization of Cao's army cannot be achieved in one day, so in the process of manufacturing the catapult car, the parts here are a little worse and that part is a little worse. In the end, the assembly will naturally be a lot different.

Cao Chun wanted to say something, but suddenly heard the horns outside the city ringing together, and the golden drums were made, like a violent hurricane passing by Yuyang City, shaking the earth.

"They are going to throw a stone!"

『Do not to escape!』

The sound of the warning gong seemed to be trembling.

The sound of war drums and horns outside the city became increasingly fierce, as if they were about to directly knock open the Yuyang city gate.

Yuyang City shivered in the torrent and groaned in the impact.

The drums became more and more intense, just like a mountain collapse and a crack in the ground.

With the sound of war drums, stone bullets rose into the air, and the sharp sound of friction between the air sounded like a sarcasm, mocking Yuyang City.

These stone bullets rushed into the sky, and then slowly rose to the highest point under the eyes of everyone, becoming a small black dot, and then fell from the sky like thunder and smashed hard towards Yuyang City!

"boom!"

『Boom! Boom!』

All the meteors fell to Yuyang City.

The walls of Yuyang City trembled and shook at this moment, like a wounded beast, sending out a shrill miserable pill.

The city gate tower on the top of Yuyang City was the first to be hit and suffered a devastating blow.

The stone bombs falling from the sky carried huge kinetic energy and potential energy, easily penetrated the roof of the city gate tower and destroyed the beams and pillars. Soon the city gate tower was flying in the sky with bricks and gravels, creaking and squeaking, and finally collapsed.

In Yuyang City, the temporarily installed horse face is also unable to withstand the attack of stone bullets because of its weak support point and insufficient thickness. As long as it is hit by three or two shots, it will shake and then fall to the city with the next stone bullet.

The utensils and huts piled up on the city wall are all made of wooden structures, and are basically vulnerable. As long as they are hit by stone bullets, they will basically crack and fly, turning into scattered wood.

The only thing that can be persisted in is the city wall of Yuyang.

However, even though Cao Chun has repaired a lot of the exterior wall, its structure is no longer complete. Under the bombardment of stone bombs, many of the blue bricks on the exterior wall collapsed and fell off, revealing the rammed earth layer of the core, like cracked wounds.

As a position to resist the invasion of foreign races in the north since the Spring and Autumn Period and the Warring States Period, Yuyang's city wall is almost the pinnacle of this era. The rammed earth is strong and the stones are neat. Even after experiencing wind, frost, rain, snow, and war, the Yuyang city wall still protects all living things in the city wall as much as possible, just like a mother instinctively guarding her children with her arms, no matter whether the children are well-behaved, stupid or smart, even if they are scarred and bloody.

『Counterattack!』 Cao Chun hid under the battlements of the city wall and grabbed the leader of the catapult cart, 『Counterattack! Did you hear it?! Counterattack no matter what! Otherwise I will chop your head first!』

The leader was sad, "General! I, I...or if I change to a lighter stone bullet, I might be able to throw it further..."

"Then why don't you go quickly!" Cao Chun yelled.

Taking advantage of the catapult outside the city loading the second round of stone bullets, the leader ran away with his head and rolled and crawled away.
