For unknown reasons, an era silently came to an end, all realms were separated, ancient giant spirits disappeared one after another. Thousands of years later, young Nie Tian managed to travel back into ancient times with the help of a drop of blood…

Reborn with the “Devil’s System,” he must now collect souls, gain abilities, and exact revenge on those who ruined him.But each power comes with a cost—and the devil never makes a deal without expecting something in return.As Elias grows stronger, unlocking deadly skills and forming uneasy alliances, he faces an even darker truth: his rebirth is part of a much bigger, bloodier plan.
