Rebirth's Omnipotent Travel System

Traveling through the parallel world and living a new life, Tianyi will definitely live a new life. Yu-Gi-Oh!, Attack on Titan, Douluo Dalu, Battle of the Sky, Naruto, Ace Censor... All left his footprints. Looking back, Maoque Wu, Masaki Kyoko, Mikasa, Ani, Christa, Zhu Ziqing, Ning Rongrong, Hinata, Huang Xiaoyan... The author of many works has not read them all, but I will try my best to read them and integrate the protagonist into the plot. As for why I should write it, I will tell you because the girl is beautiful? A harem is a must. Who doesn't have a harem dream? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
