Hu Feng, a high school student, accidentally embarked on the road of modifying the world.

Gu Chaoyan is the eldest daughter of the Gu Family, yet the least favorite one. She is mostly despised and belittled by everyone around, only because she isn’t pretty.

Being dragged forcefully, the young man found himself in a world where cultivation and magic exists. In this vast multi-worlds, the blood of the innocent and the blood of the guilt are spilled like it's nothing.

“I finally found you,” The words sent a jolt to his soul as an unknown yet familiar blurred memory played in his mind. Embraced by the unknown woman, they shared a kiss to his surprise.

Wearing a ring that held half of the power of his past life, the young man ventured to find his women and retrieve his lost memories.

Oh yeah, he was transferred naked.
