Legend has it that in ancient times, nine powerful men sealed the "Secret of Immortality" they knew throughout their lives in nine different ancient tombs before they died. Each tomb contained a page of the "Nine Nether Secrets". The "mystery of immortality" can be solved by collecting all nine pages of secret records. However, every page of the secret book is guarded by a fatal curse and mechanism, and no one has successfully collected them for thousands of years.
Very suspenseful, a bit like Tomb Raiders Notes
The content is beyond common sense!
