Cracks as thick as fingers appeared on the black rocks that were as smooth as mirrors. Then, they spread out like ripples. Eventually, in cracking sounds, the rocks crumbled, and the city wall collapsed. Even many Crouching Tiger Cannons and Fiery Crow Ballista fell to the giant pit of collapse. A lot of disciples of Roaring Tiger Hall broke their arms or legs and were bleeding when the cannons and ballista hit them!
The towers on the city were all bearing dozens of times the standard gravity. People with low Cultivation and the defensive weapons alike were crushed to smithereens!
Of course, elsewhere, the Couching Tiger Cannons and the Fiery Crow Ballista were in zero gravity. They were floating in midair, shaking, together with a lot of broken rocks. The disciples of Roaring Tiger Hall were waving their hands and feet in midair as if they were being drowned. However hard they struggled, they could not reach the land.
Boom! Boom! Boom! Boom! Boom!
