A brief introduction to the story of Lai Buyi, a dragon seeker and swordsman.

In Song Dynasty, Lai Chengshan, a famous geomantic master, sought auspicious caves for local tyrant Qinhuai (the father). However, it is clear that the Qin family is rich and heartless, and a demon minister will bring disaster to the country and the people, and he also wants to play on the grave to extinguish his arrogance. However, Qinhuai, a senior in high school, forced him to swear. If the Qin family is in trouble, the Lai family will suffer first. Due to repeated leaks, Hou Cheng suffered a disaster and lost his son many times, which affected his youngest son, Lai Buyi.

After a night of heavy rain, the coffin of cloth rushed out before he died. The dreamy old man (Yu Ming) once performed his wonderful work to save him, and gave him a life-long stunt to transform Buyi. The old man even gave Buyi a dragon sword and told Buyi to use what he had learned to solve the danger of his life.

Lai Buyi is proficient in numerology, solves problems for others, and takes saving the country and the people as his own responsibility; However, his life was dominated by fate, and he suffered many disasters. At that time, Song Gaozong Kang Wang (Li Longji) was hunted down by nomads from behind, and Buyi stepped forward to help Kang Wang secretly. He used magic to let Kang Wang ride a mud horse across the river and set a fire dragon array in Jingu. With a flick of the finger, the nomads from the army retreated. Buyi was named a Buddhist for his meritorious service in rescuing Kang Wang, which made his friend Fu Tianhua (He Baosheng) jealous.

Our country does not hesitate to please treacherous court official Qin Gui and compete with Buyi. Lai Buyi and Tianhua used to be friends in need, but in the end they will fight to the death. Buyi has unique skills, but he can't make self-determination all his life. He has an iron heart, but he still can't beat Long Mai's established providence in the Song Dynasty.

Although Buyi is surrounded by three confidantes, including the fallen princess Zhao Rong (Li Meifeng), the princess of the State of Jin Wan Yanfeng (Lin Qixin) and the bosom friend Mei Qing (Liang Xiaobing), Buyi is hard to kill with his sword, nor can he share his white head with him. Buyi thought that he was doomed to be lonely all his life, and he couldn't help feeling sad. And how to solve the friendship between Buyi and Tianhua? Qin Gui's slanderous remarks mean that the Buyi people have made amazing achievements, which is bound to be a catastrophe. Emperor Gaozong decided to hunt down Lai Buyi, a geomantic master who defended his country with his sword and fought against his fate. Can he turn the tide and eliminate this disaster?
