I Was Terminally Ill and Was Fed the Secret Book of Cultivating Immortality.

Fang Hao, who graduated from university, was diagnosed with terminal cancer. Feeling cold, he gave up and continued treatment and chose to return to his hometown, preparing to spend the last few months with peace of mind. An express delivery shattered the peaceful life he had imagined. Someone actually mailed him a copy of the secret book and resources for cultivating immortality. Fang Hao practiced it doubtfully, but he didn't expect it to be true. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
