The Immortal Has Come to Open a Time Gate for the Nation, Just for Fun

March 2026: A powerful immortal with a chuunibyou, goofy style opens a space-time passage for Huaxia, leading to Earth 2 a hundred years in the past, in 1926, so Huaxia can make its mark there.

At first, everyone seriously assumes that this is a large-scale transmigration. But before long, they realize that the powerful immortal is actually an adorable goofball who has brought along several beautiful fairy sisters to join in the fun. In effect, he has given everyone an invincible cheat. The story's style veers further and further off course: on one hand, they earnestly transmigrate in organized groups to develop Earth 2, fight the Japanese invaders, and teach the Westerners a lesson; on the other, they keep the big shot happy to get all kinds of superpowers and real-life anime figurines. Every so often, they also pop over to worlds with completely different styles, from cultivation to science fiction. In short, they build things while having fun everywhere, with the big shot serving as everyone's invincible System cheat.
