During the School Dormitory Check, My Immortality Cultivation Technique Was Discovered

Li Changsheng traveled to a different world, his system awakened, and he was given a set of immortality cultivation techniques. But he sadly discovered that there was no spiritual energy in this world. It was not until the dormitory check that the school beauty brought the student union members to 502 and unexpectedly found an ancient book. "Li Changsheng, what kind of book is this?" The system that had been silent for many years issued a prompt: "1. Continue to conceal it to avoid exposing the existence of the immortal cultivation technique." "2. Tell the truth and be rewarded with 100 experience points in cultivating immortality." Li Changsheng chose the second option without hesitation. "Now that the matter has come to this, I will no longer hide it. This is a genuine book on how to cultivate immortality." Facing the sneers from everyone, Li Changsheng shouted loudly. "Sword comes..." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
