Genshin Impact: Waiting for a Ray of Light

[Genshin Impact fanfiction] [Proceed with caution: angst] [No CP = ship whoever you want] [Episodic] [Male protagonist] [Xiao, Venti, Zhongli, and other playable characters, along with some minor characters] [Bad ending warning]

Mu Jiangyue is an unremarkable high school history teacher. Half his life was a mess, and the other half was lonely. Perhaps the only thing that set him apart was playing a certain game in his spare time. But who could have guessed that one day he would end up in Teyvat, with a rather strange System to boot, whose motto was “Save the angst, and deliver all beings”?

…I said save the angst, not create new angst, hey!
