GENSHIN: Devourer of Archons

(NO ARCHONS WERE HARMED) Without further ado: a person from our world ends up in Genshin Impact. He knows a bit of the canon and wants to use this knowledge to gain something useful for himself. He hasn't received any major advantages and will focus on alchemy and crafting cunning evil plans. In many fantasy stories, there's a System that all residents of the world have, but I don't recall a protagonist choosing to create such a System as their main goal to sit at the top and reap all the benefits. After all, if you think about it, the Genshin world already has individual elements that could be used to construct it... So, meet the future (in a very, very distant future) planetary Archon and God of the System!!! English is not my native language
