At the same time, my wife is myself.

After Qian Yuan was hit by a dump truck and flew away, he came to the seventh singularity of FGO, the absolute Warcraft front. What should he do if the world is about to be destroyed?
Fortunately, when he was created and flew away, his soul was copied into many copies and spread throughout the heavens and worlds.
Mei from Honkai Impact 3rd, Rai Kagetsu from Genshin Impact, Rin Tohsaka from Warcraft V, Shoko Toyokawa from MyGO, Ai Haibara from Detective Conan, W from Arknights, Illya from Majiki, Athena from Godslayer...
Qianyuan can share power with myself in different dimensions and travel through the world, but why am I only a girl in other worlds?
My wife is actually me?
