Rowling transmigrates into the Marvel universe, only to find himself confronted with a dark cosmos spearheaded by four notorious serial killers. Fortunately, he acquires a mutated map editor. He can freely modify character attributes, create 3D stereoscopic views, distinguish friend from foe, access thousands of skills, transform skill effects, and freely traverse terrain... As Rowling accumulates anomalies and upgrades the map editor, discovering more and more features. With a single thought, he can edit objects, conjure characters and abilities from nothing, create all things, and unleash divine power over the endless universe! Until he becomes an immortal god! From that day forward, Rowling becomes the endless nightmare of OAA, the Supreme God, and other deities.
