บท 198: Chapter 198: What do you want to do when you go back to the past?

Wang Yunxiao suddenly remembered something: he had looked over all his brothers but had completely forgotten Zhou Qing.

Besides meeting her last night, he had never seen this girl who seemed to have no presence at all.

Hold on, let me sort this out.

If time had rewound and Zhou Qing hadn't hanged herself, would the ghost that passed him the rope last night still exist?

If time rewinding could bring the dead back to life, then could the casualties from the teams that fought last night be revived?
