I'm Fan Xian's Dimwitted Younger Brother

Born as Fan Xian's twin brother, Li Chengyou suffered a brain injury during an attack at birth. From then on, his mind remained as innocent as a child's, though his extraordinary martial bones were unlike anything the world had ever seen.

Recognized by Emperor Qing at the age of six, he became the only “foolish” prince in the Great Qing imperial palace. Yet amid everyone's hidden schemes, he was the one patch of pure ground where people were willing to offer their true hearts. Emperor Qing forged him into a secret human weapon, his elder brothers sought in him the warmth they had lost, and Fan Xian never forgot the little “shadow” who had followed him around the seaside in Danzhou.

The court was rife with intrigue, while danger lurked throughout the martial world. When a shocking conspiracy finally erupted at Mount Dadong, Emperor Qing coldly ordered, “You'er, kill him!” But the blade was pointed at his own flesh-and-blood elder brother. What choice would fate force him to make?

When an innocent heart faces imperial power and its machinations, can this pure ground, nurtured with true affection, become the last light to illuminate this dark age?
