This is How Immortals Cultivate

Good news: Fang Suichu has transmigrated to a world brimming with spiritual energy, waking up to find himself within a sect as a newly initiated disciple, complete with a system. Bad news: This immortal world is fake. The so-called immortal path here is closer to Chinese Cthulhu mythos, involving the cultivation of various bizarre curses. Furthermore, the so-called newly initiated disciples are actually being sold to these strange sects as cultivation materials. Even worse news: Fang Suichu's system genuinely believes this to be a legitimate world of cultivation.
