The city walls today were not as sturdy as iron like everyone thought. They were not built with regular boulders, but with materials like stones, yellow mud, glutinous rice, glutinous rice juice and lime. Chengan District was just a relatively remote district in the north. How sturdy could the city walls be?
It could block ordinary attacks without a problem, but it was somewhat insufficient to counter Jiang Pengji's improved catapults.
Moreover, it was a giant catapult. In theory, it could even make a deep hole in the city walls of Shangjing that year, let alone the city walls of Chengan District. The city walls were solid, but the power of the extraterrestrial objects was beyond imagination.
Even a demolition crew was not that cruel!
Except for Jiang Pengji, Zhang Ping and the audience in the streaming room, no one knew that the catapult was actually that powerful.
