Time Travel·nano Core

I am a time-traveler named Chenye. This is my second time-travel. I have time-traveled into an animation with a not-so-good ending. For this reason, I decided to use the power I gained from my first time-travel to save this imperfect ending. Warning before viewing: This is a test work, I am also a novice, my writing is not good, please forgive me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
