Can You Beat Genshin Impact Using Only Xingqiu?!

Genshin Impact has a tendency to release characters that sorta replace past characters. Examples of this happening are Barbara with Kokomi, Diluc with Hu Tao, Noelle with Zhongli, and Amber with… well, everyone. However, there are some that still hold their own, even all these updates later. For example Bennett is still one of the best buffers in the game, Xiangling is still an amazing sub dps, and Xingqiu is one of the best and easiest to get hydro appliers in the game. Yes, Yelan and Furina are better, but they’re both a lot harder to get than Xingqiu. With this being said, he's not really a main DPS. With that being said, can Xingqiu do everything on his own with how good he is? Because I'm stupid, I'm gonna answer that question.

Rules:
I can only use Xingqiu in battle
Any puzzles that require another element can be completed with another character
No healing items in battle
No co-op
All swords are allowed
