Tomb Robbery Sign-In: I Am Cheating in the World of Tomb Robbery Notes

(It deviates a lot from the plot of the original work.) After an unexpected time travel, ordinary young man Lin Feng fell into the mysterious world of "Tomb Robbers' Notes" and became an ordinary but ambitious tomb robber. As soon as he woke up, he was given a "Tomb Robbery Sign-in System". Every time he entered an ancient tomb, he could sign in and receive mysterious rewards. Basic tomb robbing skills, ancient mechanism cracking techniques, danger warnings, and even the long-lost inheritance of the Nine Sects... The system's sign-in rewards gradually made him stand out, and people in the Nine Sects gradually noticed this mysterious "junior." During the tomb explorations where he narrowly escaped death, Lin Feng met Wu Xie, Zhang Qiling, Fatty Wang and other partners who depended on each other for life and death. They go to the Bronze Gate together and gradually uncover the eternal mystery of "immortality". However, as the system functions continued to be unlocked, Lin Feng also faintly realized that all this was not just a coincidence. The assassins of the Wang family are secretly watching, and there are undercurrents among the Nine Gates, and his system seems to be inextricably linked to the unknown secret behind the Bronze Gate. Should he sleep with the bronze door and guard the mystery of eternal life, or should he break through the shackles of life and death and return to the real world? Faced with the choice between immortality and return, how will Lin Feng respond? The system's ultimate mission gradually emerges, and an endless battle of fate is about to begin...
