Wang Cai is so powerful that even Mu Can, who has been with him for so long, doesn't know his full strength. Since meeting Wang Cai, Mu Can has never seen an enemy Wang Cai couldn't handle. Whenever Wang Cai took action, he would immediately defeat the opponent. This was true for even the supreme beings of the Supreme Interface, and all other enemies were no different.
Because of this, Mu Can had never seen Wang Cai fight with full strength. The only time he saw Wang Cai at a disadvantage was previously in the Hidden Gold Tomb that sealed the green-haired giant hand. At other times, it was always Wang Cai making others suffer, never the other way around.
