Female Lead: Lin Zhao (24), a graduate student in archaeology. Her grandfather was a former member of the Nine Gates and once served as Chen Pi A Si's deputy. Due to her unusual bloodline, she was chosen by the Tomb Keeper System. Cool on the outside but warm-hearted within, she excels at deciphering ancient scripts and solving mechanical puzzles, and feels a fated familiarity with Zhang Qiling.
System: The Bronze Lamp's Guidance, shaped like a bronze goose-and-fish lamp that can be stored inside a pocket watch. Its objectives are clear: before Zhang Qiling enters the Bronze Gate, repair the fractures in his memory, stop the backlash of immortality, and uncover the ultimate secret behind the System. It issues time-limited missions. Failure costs lifespan points, starting at 100 years; reaching zero means death.
Worldbuilding: Combines the original setting of The Grave Robbers' Chronicles, including the Nine Gates, the Zhang family, the Bronze Gate, and the Ultimate, with a new Tomb Keeper system: an ancient, mysterious organization dedicated to protecting the Ultimate. The System is its last surviving legacy, and its goal is to correct the imbalance of the Ultimate caused by human greed.
