In Academy City, magic and science coexist in an unwavering power struggle. Toma Kamijo, an academically-challenged student in Academy City, wields the power of the Imagine Breaker in his right hand, which allows him to completely negate all supernatural powers – as well as his own luck. When he happens upon a mysterious nun named Index, whose mind has been implanted with the Index Librorum Prohibitorum – 103,000 ancient texts banned by the Church – Toma’s luck is about to be pushed to its limits when he finds himself in the middle of a war he never expected!

Xiang Yu was perfectly content with his mediocre life on Earth—average job, average apartment, average everything. That is, until he woke up in the legendary World of Cultivation, where martial artists fly through the skies and immortals battle over ancient treasures.There's just one problem: Xiang Yu wants absolutely NONE of that action.Armed with only his wits and a peculiar system that doubles his exp every 24 hours, Xiang Yu has one goal: become powerful enough to live in peace without getting involved in those ridiculous “protagonist” situations. No ancient tombs. No tournament arcs. And for heaven's sake, stay FAR away from anyone named Chen Mo, Lin Feng, or Li Yao—those names practically scream “main character who will drag me into deadly situations!”Starting with strength stats so pathetic he can barely lift a cultivation manual, Xiang Yu must somehow survive long enough for his exponential growth to matter. After all, doubling zero cultivation talent still equals zero... at first.Follow Xiang Yu on his hilarious journey from zero to hero as he desperately tries to stay invisible while his power skyrockets beyond control! Watch as he dodges cultivation tournaments, avoids suspicious elders bearing gifts, and runs the other way whenever someone mentions “ancient inheritance” or “chosen one.”Join the adventure of the most reluctant cultivator in history whose only wish is peace and quiet, but whose exponential growth makes him the most terrifying force this cultivation world has ever seen!

The apocalypse descends, zombies and monsters appear, followed by System Leveling, which grants skills to all survivors.With the collapse of law and order, some become powerful while others remain weak, and so the dark ages begin.
