Feel Sorry! He Loves to Tease the Evil Host

[Two male protagonists + quick travel + 1v1 double cleansing + independent unit story + crazy criticism of yandere + forced love] Baizhu, the little immortal who has just ascended, is accidentally tricked into doing tasks by a system that is about to be scrapped. In different worlds, he always encounters some strange male protagonists. World One (Normal): The cold CEO who is plagued by cold poison loves to take him to a private room and let him feed the medicine himself. "Baizhu, don't leave me. No medicine will work. You are my only antidote." World 2 (somewhat abnormal): A photophobic boy with a red snake tattoo on the back of his hand seems to be hiding some dark secrets. Living in darkness for many years, he was lonely and cold-blooded, and did not know what warmth was. Until that person appeared and became the only light in his life. "Brother, don't leave. Without you, I will die." ..... The further back you go, the system discovers. The little fairy it abducted seemed not as innocent and weak as it imagined. Is it using Baizhu to accomplish its performance, or has it been used by him to do something? It is unknown.
