Because of an accident, Su Mubai came to the Teyvat continent and obtained a system called [Reincarnation of Destiny].
A strong force erases its existence. Only by making people in the world have strong emotions towards him can the memory be restored.

Mavica: I have been chasing your back, and I will not let you leave this time.
Egoria: Judgment of fate, judgment of gods, but your existence cannot be judged.
Raiden Zhen and Ying: We have been pursuing eternity, why can't even your existence be left behind;
Wendy: The wind of freedom will stay for you, but where are you?
