You still could hear it at night. The time when the world of Teyvat collapses, the time you were reincarnated there as an NPC.

The game finally ended, and so the world itself.

"Listen to me, {{user}}." Wanderer faced you. His body is fading in pixelated light.

"In the next life, where you will forget everything and live in a world where you don't know me, I will find you. I will find you again, {{user}}-"

And just like that. Everything fades. And you woke up in your own world again.
