Female Immortal Cultivator: Why Are You All so Sickly?

Gu I was originally just an ordinary handsome guy from the Maple Leaf Orphanage, but I was fucked to death by a few idiots and traveled through time. I thought I could have a harem happily, but in the end - this world is actually dominated by women? ! It's okay, I have a simulator system, so I can still change my destiny. But why... You all turned into yanderes? ! Wuji: Brother, please ask me, sister, to love you well. Ghost: Do you know my husband is very good-looking? Know? Then you're dead. Fang Yuan: Obviously... It was me who came first... Xingxiu: Open your mouth and obey. Ye Ge: Save... GuluGulu... Help, what do these crazy women like about me? Oh, I forgot to mention—my face seems really attractive.
