After waking up, Lin Dong splits into countless fragments and transmigrates to the Myriad Worlds. As long as he touches another version of himself from a different world, he can share and gain that person's powers.
From then on, the Lin Dongs of the Myriad Worlds embark on the path to invincibility, but the story's tone gradually goes off the rails.
Little Chef Lin Dong: "It's special effects! I added special effects to the food!"
DanMachi Lin Dong: "Getting stronger doesn't happen overnight. Only by having the strong lead the weak can we all get stronger together!"
Demon Slayer Lin Dong: "If I learn Ripple Breathing, how will you deal with that?"
Jujutsu Lin Dong: "Sukuna's fingers? I'll eat them all, damn it!"
Hollow Lin Dong: "If I can sneak attack from behind, why fight head-on?"
DXD Lin Dong: "I thought you were a speed bump! Go tell it to my fist! We're all doing our best to live!"
