Genshin AU - Infected

*This fanfic is based on the AU made by @peixti on instagram. Make sure to check out her work. The cover is also a drawing made by her. Make sure to follow her for the original (and better) content* The world has lost its shine, that much he knew. It took just a glance, and the slanted perspective gave out more than enough. It was dead, in its own right. The world as he knew it was placed aside for the time being, until he'd figure out both what happened to him, and what was forcing the infection to spread. What was the cause? How did it all even get there? Too many questions, and only a single person to try and find them. It was time for Ken to do what he knew best and cut apart all his foes.
