A Marriage Contract Will Lead to Three Years in Prison, and You Can Go Out of Fengshan Mountain to Listen to the Dragon's Chant

Three years ago, Lin Ao was murdered and imprisoned. His family was wiped out, leaving only his sister missing. He fell into Longtan Prison, the most dangerous prison in the world, and met the divine enlightenment. And he possesses supreme medical skills, financial resources, rights, and various lost skills. When the opportunity came in three years, the cold poison in the master's wife's body was expelled, and it was time for Lin Ao to go down the mountain for revenge. I was told that there were seven senior sisters of my own at the foot of the mountain. He took the aid his master's wife gave him and went down the mountain. As soon as he arrived at the bottom of the mountain, he met his sister in front of the grave, who was being humiliated by his boss. After some investigation, I found out that my sister had been subjected to such inhuman torture over the years. Lin Ao will definitely repay all the hatred he had from three years ago and in the past three years a hundredfold!
