Legend has it that tens of thousands of years ago, there was a paradise where many dragons lived. Because the real dragons needed to absorb a lot of true qi, the air on the earth became thin and humans were on the verge of extinction. In order to save humans, the survivors created weapons to kill dragons and began to kill dragons. The dragons fled everywhere. The last dragon escaped to the Central Plains and sealed the hope of the dragons underground. The energy that burst out when the dragons died filled the air. People who practiced called it dragon soul. Tens of thousands of years later, Bai Wuxia from the dragon slayer came to the Wan family to look for the escaped real dragon and hid his identity in the Wan family. The protagonist Wan Yi is a waste youth of the Wan family. By chance, he obtained the soul power of the real dragon. It happened that the court was preparing to conquer the Wan family, so the story of the three parties of the dragon slayers, the Wan family and the court happened. In the end, Bai Wuxia and the court eunuch Yu Huatian both died in the Wan family, and also killed the head of the Wan family, Wan Tianba, and the young genius of the Wan family, Wan Sen. But according to Wan Yi, Bai Wuxia and Wan Sen were not really dead.
