Three years ago, Ye Chu was forced to take the blame for his eldest brother and sent to prison. In prison, a mysterious old man took him as a disciple and taught him martial arts and medical skills. The old man told him: You possess the true dragon bloodline, but your true dragon bone was dug out, producing resentful dragon Qi; if it cannot be resolved, you will not live past twenty. Three years later, after getting out of prison, the Ye family actually made him marry into the Jiang family as a matrilocal husband to bring good luck to the comatose eldest miss. Everyone sneered at him as a trashy son-in-law. But what they did not know was that Ye Chu's master was precisely the Pharmaceutical Emperor renowned throughout the world. Even less did anyone know that the day his true dragon bloodline awakens, the entire Jiangdu will tremble because of it. Once the true dragon comes out of prison, the winds and clouds of the world change.
