[Fanfan+adventure+daily+single female protagonist]
This is not the original Teyvat, but the Teyvat that the star train came to hundreds of millions of years ago.
Ye Bufan was originally a happy commander at the Star Railway and a fun-loving person. However, he was teleported to the Teyvat continent by Aha, where he met the person who would accompany him throughout his life.
Traveling to four countries together, he was thwarted by his boss Happy Star.
During the journey, he suspected that he had been to Teyvat before.
