Cao Zhen didn't expect that even though he promised to leave a path for the descendants of the City Lord of Wansheng, the City Lord of Wansheng would choose to disregard his descendants under such circumstances. He also didn't expect that the cowardly City Lord of Wansheng would self-destruct.
Moreover, even if he knew the opponent was about to self-destruct, there was no way to prevent it.
Unless his strength was significantly greater than the City Lord of Wansheng, completely capable of suppressing the opponent, otherwise, it's impossible to stop a True Immortal Realm from self-destructing, because such self-destruction isn't about demolishing the Immortal Palace but rather drawing the power from the Immortal Palace back into the body, exploding their physical form!
After sensing the opponent's intention to self-destruct, his figure quickly retreated.
