I Became Changli to Guard Humanity's Eternal Peace

When anime superfan Lu Changli wakes up in another world, he's granted an S-rank Role-Playing System—and his first character is the legendary Changli. With spiritual energy about to surge across this new reality in just one month, he must master his role to survive. From powerless spectator to cunning mastermind, Lu follows a dangerous path: bystander, pawn, player, and finally—the one who rewrites the rules entirely. As he cycles through multiple personas, all roads lead back to Changli, the guardian destined to protect humanity for ten thousand generations.
