You were made to take the blame and go to jail, but you weren't made a master of both medicine

Five years ago, Qin Ran, who was mentally challenged, was forced by her parents to take the blame for her brother!
In the Dragon Prison, he learned extraordinary skills from his masters: medicine, martial arts, and magic, which he mastered with ease.
Five years later, he was released from prison with extraordinary skills.
I am no longer the mentally challenged person I was five years ago.
My adoptive parents and those who tried to bully me, prepare to tremble.
Watch as Qin Ran dominates the battlefield, charms beauties, and shakes the world with his martial arts.
The world is destined to tremble beneath my feet.
Global alert! The dragon has been released from prison, invincible...
