Instance Raider: Worlds Beneath My Feet

After the cataclysm, monsters roamed everywhere. Reincarnation Space became humanity's last hope. Everyone who turned eighteen had to enter film or game instance worlds to complete tasks in exchange for points, which could be used to acquire cultivation techniques, superpowers, weapons, and opportunities for longevity. The strongest among them could destroy entire nations. Many died horribly because they were unfamiliar with the storylines of those instances. Leon was transported into this world, knowing every storyline, every opportunity, and every trap. He also awakened the Reincarnation Assistance System. The previous owner of his body had endured endless humiliation while pursuing Raelynn, but Leon immediately cut off all emotional ties and resolved to turn the tables using his foreknowledge. For his assessment instance, he chose a familiar instance, seized key items, gathered allies, intercepted hidden rewards, foiled others' schemes, and earned top scores, leaving all other newcomers far behind. From then on, he traveled through countless instances across various realms, mastering multiple forms of supernatural power. He crushed veteran reincarnators and rival prodigies alike, competed for primordial inheritances, built his own faction, and steadily rose to dominance. In the end, he swept through all the cycles of reincarnation and claimed the supreme throne of Reincarnation Space.
