How many countries did Chu destroy?

During the Warring States Period, the Chu State occupied the entire southern region, from Hanzhong to Wuyue. A large part of its territory was acquired through expansion. When the northern vassal states were busy competing for hegemony, the Chu State annexed the south. It was a small vassal state, so Chu State was the one that destroyed the most among the seven heroes of the Warring States Period. It successively annexed small southern states such as Tang State, Deng State, Shen State, Xi State, Jiang State, Huang State, Chen State, and Cai State, and invaded the Central Plains.
