Then, accompanied by the fire, five earth-shaking sounds of cannons rang one after another.

"Boom boom boom boom boom boom boom!"

Driven by huge kinetic energy, five huge stone bullets weighing 250 kilograms were shot out from the thick gun barrel. After a short flight for a while, they hit the wall of Hangu Pass heavily, causing countless smoke.

At this moment, countless Qin soldiers on the wall felt that their feet suddenly and violently shook, and many unprepared people fell to the ground.

Bai Qi also staggered under his feet. If it weren't for the place where he was standing far from the place where the stone bullet shot, the chief general of the Qin army might have made a big mistake like his many subordinates.

However, at this moment, Bai Qi had no intention of taking care of these things. He pulled away the guards gathered around him, rushed directly to the edge of the wall, and looked at the place where he was shot.

Five very obvious big pits appeared on the wall of Hangu Pass. Countless sand and stones fell in the pit. There were also very obvious cracks on the walls around them, extending two or three meters away in all directions like spider webs before stopping.

No matter how calm he was on weekdays, Bai Qi couldn't help but look extremely surprised on his face.

Suddenly, Bai Qi started shouting wildly.

"Boundist, where is the Bowman? Shoot me and shoot hard, don't let the Zhao people continue the weapon!"

On Pingtou Mountain, Bao Yuan was also stunned.

Just one round of artillery bombardment has caused such obvious damage to the wall. If there were a few more rounds...

This effect is really too strong, and I don’t know how many times stronger than a catapult!

Zhao He laughed and said to Bao Yuan: "Do you understand now? Due to the shooting arc of our catapult, the stone bullets fell directly above the city wall, that is, the top of the rectangle consisting of length and width, which can stand on the top of the city wall, so the high wall can provide enough buffering force to resist. However, this kind of heavy artillery is different. The shells of heavy artillery are similar to vertical shooting, so it directly bombards the plane composed of length and height in front of the city wall, and the thickness in front is far insufficient compared to the top. With the increase in power and the reduction in thickness... you see, this is what we see now."
