Lu Yao accidentally transmigrated to the world of Honkai: Star Rail and awakened the Myriad Worlds Curio Merchant System. From then on, he embarked on a life of commerce!
Jarilo-VI, Bronya: "Th-this... In another world, there's someone who looks exactly like me? What? You call her Twin Turbo Duck?!"
Seele: "Black Seele and White Seele? I'd quite like to meet them!"
Xianzhou Luofu, Qingque: "Where'd you find this Pink Elf model? She's pretty cute. The Elysian Realm? Hmm, there's a place like that in the starfields? Never heard of it!"
Armed with the Myriad Worlds Curio Merchant System, Lu Yao traveled among the various factions of the Star Rail World, selling all kinds of strange goods. Later, he happened to acquire a Void Gate. From the other side of the gate came a voice: "Sigh, life on the moon really is boring. I kind of miss Mei..."
Lu Yao declared, "Oh! It's time to take my business into the Honkai 3rd world!"
