Can You Beat Genshin Impact Without Spending Mora?!

Mora is a pivotal currency in Genshin Impact. It is used to buy and do most things in the game, and having no mora in Genshin basically means that you can't play Genshin. So what would happen if we decided not to spend any throughout the entire game? This is the worst idea I've ever had.
Rules:
I cannot spend mora at any point in the challenge.
All characters are allowed.
