Li Yifei treated Xu Zhenguo for a week, killing off the cancerous lesions inside his body. This process wouldn't be too fast, especially since it's not Li Yifei himself, and it's dealing with cancer cells. Xu Zhenguo is now in the metastasis stage, almost late-stage. Many organs have undergone some degree of pathological changes. If it weren't for this accident with Li Yifei coming over to check, it might not have been discovered, and by the time he really felt something was wrong, it would probably have been too late.
After this week's treatment ended, Li Yifei checked again and found that Xu Zhenguo had completely recovered. However, since some organs had undergone pathological changes, he still needs some time to slowly recuperate and recover. Even so, this result is enough to make Mother Xu very happy. Nowadays, she has nothing but praise for her son-in-law Li Yifei, utterly satisfied.
