Dragon Emperor's Heaven-Killing Scripture

The good-for-nothing boy fell off a cliff and survived, but got the ancient dragon's blood inheritance! Chen Jin was born with a weak pulse and suffered humiliation in the Chen family. Three years ago, his father died in battle to save the family leader, but he became an abandoned son of the family. Even his childhood sweetheart Chen Qingzhu treated him coldly. In order to collect ten fire grasses, he was forced into a desperate situation and fell off the Black Wind Cliff. But I didn't expect that there would be the remains of the ancient Dragon King at the bottom of the cliff! A drop of dragon's blood enters the body, reshapes the abandoned veins, and obtains the supreme skill "Blue Dragon Transformation Technique"! The fifth level of body tempering was achieved overnight! Those who bullied him, insulted him, and treated him like nothing in the past will all pay the price for their arrogance. And that girl who was once as cold as ice to him will eventually witness him ascending to the Nine Heavens and becoming the only one in all eternity - the Dragon Emperor!
