Dimensional Fusion: Traveling Through More Than Just Spells and Returning to the Battle

[Spell Return] + [One Punch Man] + [Chainsaw Man] + [Fusion Time Travel] + [The early pace is slow, but the plot advances steadily] I, Li Shiling, a former temporary worker in District 13 of "The Adventures of Jackie Chan", an expert in qi magic, and the fastest time traveler, have just done a big thing—— In the history books of the years, before the Holy Lord rewrites everything, he wrote the ending of "returning home safely" for himself. I succeeded! But the world failed... When I opened my eyes, I returned to the familiar room, quiet and peaceful, everything stayed where it was before I traveled through time. But when I opened the mobile phone page, I found that things seemed different from what I imagined—— "A ghost-level disaster suddenly occurred in Z City, and the 'Gun Curse Demon' resurrected!" "The Hero Association is recruiting a new type of magician, and the salary will be upgraded to A level!" "The special sealed item 'Su Nuo's Finger' mysteriously disappeared" … Neon lights flashed outside the window, and a huge screen scrolled through the scene of King, the "strongest human being", and Satoru Gojo, the "strongest magician in modern times" shaking hands and having a happy conversation - they actually attended a joint press conference called "Science Popularization of the Root Curse Demon and the Weapon Man". If nothing goes wrong, I did "go home". But my world has been saturated, fused, and transformed by rules from three weird universes like venom of different colors. Where should I go from here?
