After tireless efforts, he finally discovered where someone had tampered with Su Qingqing—it turned out to be a part of her brain cells.
This part of the cells controls the entire nervous system, which is why Su Qingqing was not under her own control.
Since the cells are very small and numerous, the most important thing is, once these cells are damaged or die, Su Qingqing might end up as a vegetable, or disabled, or even dead. Therefore, he was at a loss as to what to do, not knowing what method to use to ensure Su Qingqing's safety and make these cells return to normal or eliminate these mutated brain cells.
When he was perplexed and troubled, a soul-like voice came from somewhere: "Yifan, is that you?"
The voice was very similar to Su Qingqing's.
Lin Yifan suddenly looked up and saw Su Qingqing's soul, and also saw Su Qingqing's shadow.
