Childe was killed during a fight and Zhongli couldn't stop mourning his death. One day zhongli found a strange relic from the abyss and upon touching it he was teleported into a strange and modern world. It wasn't like tevyat at all, it was just like earth. Before he could investigate further he was stopped by a familiar face and voice.

"Who are you?! How did you break into my house?"

The person infront of him looked like Childe, it was him but a alternate version of him. His name is Ajax.
