When he was five years old, Xu Feng witnessed his house being burned with blood and fire, and his parents died tragically at the hands of his enemies to protect him. When he was on the verge of death, he was rescued by one of the "Top Ten Villains" who was frightened by the martial arts, and was taken to a desperate place - the Valley of the Villains.
In the past ten years, he has become the only successor in the Valley of the Wicked. He has mastered the poison skills of the evil doctor, the knife skills of the Blood Slaughter, the disguise of the Thousand-faced Man, and the light kung fu of the ghost thief... He has mastered the secret skills of the top ten demons, surpassing his masters, and has become a famous "evil boy in the world" in the Valley of the Wicked.
At the age of fifteen, he was ordered by his master to go down the mountain to seek revenge. The top ten demons thought they would unleash a ferocious beast that would subvert the martial arts world, but they never expected...
He uses poison to save people, sword skills to cut off greed, disguises himself to expose falsehoods, and light skills to help those in need. Wherever he went, the dandy who bullied men and women cried, the bullies in the fish and meat village knelt down, and the sanctimonious hypocrites showed up!
While he acted chivalrously and gained fame far and wide, he also pursued the blood feud of the past. It wasn't until he met her who was as pure as a white lotus, until he lifted the veil of his enemy, that he discovered that behind the massacre there was a shocking secret that could subvert the entire martial arts world...
He is the only descendant of the Valley of Evil and the only chivalrous light in this troubled world.
