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.
Now, seeing the living Zhou Qing in person threw his mind into chaos.
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?
Moreover, Zhou Qing is a ghost; if she's still around, what about during the day?
Wang Yunxiao suddenly understood Yan Yu'an's anxious emotions.
Time-Space Retrospection wasn't such a simple issue; it could lead to a series of problems down the line.
To put it in terms the average person could understand: one is the butterfly effect, the other is the grandfather paradox.
