I'm Doing Version Rollback in the Weird World

Others have traveled through time and brought their own system, card drawing, and old man. Lin Yuan traveled through time, and there was only a line of version numbers in his left eye. The skill is broken? Rollback - the residual copy is returned to the full version. Arms corroded by spider venom? Rollback - Return to the intact state one hour ago. Besieging the city with weird positioning beacons? All rolled back - the twelve black pillars retreated into ordinary quartzite, and not a single one remained. Outside the city, the strange son "Mirror" stared at him all night. It has copied all martial arts and swallowed all laws - but this thing called "rollback" cannot be copied. It said: "You are not Origin. You are much weaker than him." Lin Yuan said: "But I left one more thing than him - notes. When he leaves, I can take over." The mirror was silent for a long time. "Reverter - you are the only human being who can return the weird to a normal creature."
