Return of the War God from Prison

Qin Linchuan, a discarded young master of the Qin family, was framed by his stepmother and imprisoned in the deep-sea prison for five years. In that purgatory, he studied under three masters and mastered combat skills, medical arts, and the art of killing. His body became as hard as steel, his mind as firm as iron, and now he returns with supreme cultivation. The eastern state is in turmoil; the wealthy look down on him, the aristocratic families oppress him, and a marriage contract forces him. He smiles calmly, for he can heal the living with medicine and slay gods with martial arts. He plays the fool, acts decisively, settles old scores, and protects those he should. In this life, he does not seek to be king, but only to take a step on the path to heaven. — Description from novelcodex.org
