(Genshin Impact fan) (Be careful when entering) (No CP = Eat casually) (Unit text) (Protagonist male) (Mandrill, Wendy, Zhongli and other caliper characters as well as some minor characters) (be warning) Mu Jiangyue is an ordinary high school history teacher. Half of his life is absurd and half of his life is lonely. The only difference may be that he plays a certain game on weekdays. But he never thought that he would be in Teyvat in one day. There is also a strange system that says "Those who save knives will save all sentient beings"... Let you save knives, but not create new knives!
