The reclusive Xiao Shi suddenly acquires an invincible cultivation System and sets off on a journey around (and through) various worlds!
Jujutsu Kaisen: "Oh, you want to destroy humanity? You're even worse than Honkai. That won't do. Take this personality-correction punch!"
Chainsaw Man: "The Chainsaw Devil? Isn't that just a dog? Why don't you all become my dogs instead?"
Naruto: "Susanoo? Not bad, but is it as good as my unyielding Rasengan?"
Type-Moon: "Gate of Babylon? Try my newly learned Knight of Owner, an armament that makes a knight invincible! Hand it over!"
Gundam: "My Authority actually works on Alaya? Then let's all go, Bael!"
Genshin Impact: "The Heavenly Principles? Isn't that just a grasshopper? Fine, today I'll finally get my revenge!"
Honkai: Star Rail: "You look just like an old fossil. Can you do that thing? You know, that thing: inch power, skull-cracking!"
Honkai: "Old Antique, open the door! Look what I brought you!"
Fu Hua stares at the Xiao Shi before her, deep in thought. One arm is wrapped around a potted plant (of the Imaginary Tree), while the other holds a bubble gun (spitting out World Bubbles). A huge necklace (strung with cocoons of Finality) hangs around her neck.
(A crossover fanfic with Xiao Shi as the protagonist. The characters will grow, the plot will be heavily reworked, and unresolved regrets will be addressed, while keeping everyone as in character as possible.)
