After Destroying the Heavenly Dao, I Became My Nemesis's Master

It was hardly unusual for Si Ti, the undying and immortal demon who terrorized the Six Realms, to get into a fight with Jing Yue Jie Yu, the War God of the Divine Realm, and apparently smash a space-time vortex to pieces in the process. After accepting the premise of "returning to five hundred years ago," she found herself in the deepest part of the slums in Fufeng City. The courtyard was dilapidated, its surrounding wall half-collapsed, and desolation lay everywhere. In one corner, a scrawny child stood with his head bowed, blood all over his mouth and his whole body trembling. Behind him, the rotting corpse of an adult woman was wrapped in a rough straw mat, the stench hanging in the air. Beside the child was a wooden sign, a few crooked words scrawled across it: Selling myself to bury my mother Four copper coins After tossing down a few copper coins, Si Ti picked up the child and leisurely left. Once she had roughly scrubbed him clean, the child finally revealed a tender, familiar face. Si Ti sneered. "Now that you're in my hands, you're finished." "Go buy some clothes. Pick the gaudiest colors you can find. I want to see what kind of child a Demon God can raise." At the same time, the streets of Changhe Street in the Eastern Zhou Kingdom were strewn with corpses, and blood flowed in rivers. Cries of anguish rose one after another, reaching the heavens. Jing Yue Jie Yu made his way through the sea of corpses and pulled a little girl from a blazing fire. "From today onward, you are my junior sister. Your surname is Ai, and your given name is Liu Yu. Follow the righteous path and learn right from wrong. You must never become a demon again..."
