A Journey Beginning in Teyvat

A boy with no memories arrives in Teyvat. What does the future hold for him? With all kinds of powers at his disposal, will he become a Traveler in Teyvat, a captain in the world of Honkai, or perhaps a Doctor in Terra?

Mo Huiyan: I want it all.

This is a crossover fanfic set across multiple worlds. So far, the plan is Genshin Impact, followed by Honkai Impact 3rd, and then Arknights. (I guess writing fanfiction really suits me.)
