In the TV show 'Fantastic Doctors,' Liu Zhen Wei and others were tasked with performing a kidney transplant for Li Heng. There is a specialized system responsible for the allocation of kidney donors, and the hospital cannot simply grant a kidney transplant to anyone. This is done to protect the patients and also safeguard the hospital and doctors, thus involving a third party with no vested interests.

Initially, it was not Li Heng who needed the kidney transplant, but another critically ill patient named Dong Biao. Unfortunately, Dong Biao's kidney source encountered a delay, and he passed away before receiving the transplant. At this critical moment, Li Heng's condition worsened, and Liu Zhen Wei decided to use the delayed kidney source for Li Heng instead.

Is this an act of saving a life? However, this action is against the rules and can potentially lead to legal consequences. After all, Dong Biao passed away without receiving the kidney, and Li Heng received a kidney that was originally intended for someone else. The police and the hospital administration need to investigate these circumstances. Liu Zhen Wei prevented Chen Hui from participating in the surgery to protect him.

Chen Hui, who is unable to communicate normally with others, may not withstand the scrutiny of the police and hospital investigation. Liu Zhen Wei is also afraid that Chen Hui might say something incorrect, which could harm others and himself. To avoid any potential harm outweighing the benefits, Liu Zhen Wei decided to remove Chen Hui from the operating room.
