Start by Traveling Through Honkai Impact 3rd, Life Simulation Ellie

Ling Tian traveled through time, arriving in a pre-Honkai Impact 3rd civilization and connecting to a system called the "God-Level Life Simulator." But after running through several simulations, Ling Tian suddenly sensed something was amiss in this world. It wasn't normal. Alicia: "Dear Ling Tian, ​​didn't you say you'd always love Alicia?" Mebius: "Little white mouse, didn't you promise to accompany me on my journey to godhood? So, you're backing off now, my sweet little white mouse!" Padofelice: "Brother Lingtian, Sister Weierwei is going to drop some Honkai fission bombs on you because of what happened between you, Sister Ying, and Ah Hua. Come with us! It'll be too late!" (P.S.: The first ten chapters are a bit poorly written. Feel free to skip if you don't like them. Please don't criticize me if you don't like them. Thank you!!!)
