the blue cube called Beth. oh no. (Genshin Impact)

the fact that the game recommended me to look at the guide, that was insulting in my opinion. "hey, you didn't do well enough, so here's the guide to help you."
i got the cube down to half health. Kaeya is the strongest character next to my main character, so I have to level his weapon up somehow even though i got zero clue on how to get the things that i need.
oh, by the way, i was exploring.
