This novel is inspired by the Chinese Danmei novels.

When Jiang Yao first encountered Luo Xiao, the young boy resembled a piece of white paper. He was pure and untainted by the greed and despair of the outside world. Even so, the demon was moving forward, little by little and introducing various colors to this unblemished blank piece of paper, and slowly it turned into the most vivid and breathtaking painting.

Luo Xiao's path takes him on a journey across the continent with the purpose of tempering himself through bloodshed and battle. By his side is Jiang Yao, a deadly guardian angel, ready to protect him in times of need, but after understanding the beauty of the diverse world, Luo Xiao is not longer willing to merely be protected and stay away from all approaching dangers.

As the vast world allows Luo Xiao to embrace his future, he now aspires to stand at the top of the world alongside the Seventh Demon Prince, fighting to carve a path forward with relentless fierceness, ignoring fatigue and pain.
