Reincarnated as the God with a Thousand Faces, and Was Disliked by the School Beauty!

A thousand-faced creature that traveled through time and resembled slimes was rejected and sold off by the reborn empress at the beginning. The new owner also gave me a shameful name - Dudu! When everyone laughed at me for being the most useless beast, the [Strongest Transformation System] was quietly activated. Deinonychus is just the beginning, Titan Giant, Abyss Demon Dragon... Are all my incarnations! Many years later, the empress broke through the cycle of reincarnation and returned, vowing to eliminate the karma of her previous life. She slashed at my seemingly harmless body with her sword, but she hit a pair of candle dragon eyes staring at her. "I heard that you once disliked me?" Empress: ... Is it too late to regret now?
