Tomb Raiding Sign-In: I Cheat in The Grave Robbers' Chronicles World

(The plot diverges considerably from the original.) After an unexpected transmigration, ordinary young man Lin Feng finds himself in the mysterious world of The Grave Robbers' Chronicles, where he becomes a seemingly ordinary tomb raider with lofty ambitions. The moment he wakes, he obtains a “Tomb-Raiding Sign-In System.” Each time he enters an ancient tomb, he can sign in and receive a mysterious reward. Basic tomb-raiding skills, techniques for breaking ancient mechanisms, danger warnings, even the long-lost legacy of the Nine Gates... The System's sign-in rewards gradually help him make a name for himself, and the Nine Gates begin to take notice of this mysterious “younger generation.” During one life-or-death tomb expedition after another, Lin Feng meets Wu Xie, Zhang Qiling, Wang Pangzi, and other companions who would trust one another with their lives. Together, they journey to the Bronze Gate and gradually uncover the age-old mystery of immortality. Yet as the System's functions continue to unlock, Lin Feng begins to suspect that none of this is merely coincidence. Wang Clan assassins watch from the shadows, the Nine Gates simmer with hidden currents, and his System seems to be closely connected to the unknown secret behind the Bronze Gate. Will he sleep alongside the Bronze Gate and guard the mystery of eternal life, or break free of death's shackles and return to the real world? Faced with the choice between immortality and finding his way home, what will Lin Feng do? The System's ultimate mission is slowly coming into view, and a battle of destiny to the death is about to begin...
