Reincarnated as an Empty Shell, but Not Entirely Bound by the Plot

This book is about an ordinary Genshin Impact player who dies suddenly at around 4 a.m. after grinding for five-star artifacts with perfect substats. He is reincarnated as Aether, the Traveler, just as the journey across Teyvat is about to begin, and comes with a System that lets him change certain parts of the story, or at least the author thinks so. Read the book to find out more. j
