Even in Hell, We Have to Save Lives and Heal the Wounded

[Thriller game + no system + no/single female protagonist + crazy doctor =? Fierce ghosts are rampant, and strangers retreat. The hell where there is no daylight is full of mysterious alien worlds. Li Yongye, who traveled through the world for no reason, looked at the bloody sun. "Where... Is this?" Ghosts mourn, dragons pull coffins... Compared with these horrors, what is more terrifying is human nature. Ghosts eat people, people eat people! In this dark world, there is another doctor whose mission is to save lives and heal the wounded. Salesman: I am very grateful to God for curing my mania and letting me know for the first time that I have mania. Skeleton monster: The divine doctor cured my osteoporosis, and now I am lying quietly in the grave and having a good sleep. After the four forbidden areas, there is another humanoid forbidden area... (Ps, there is a high probability that there will be no female protagonist)
