Bai Mei, the peerless master known as Dugu Qiufei, withdrew from the world sixty years ago and lived in seclusion on the top of Kunlun Mountain.

Lu Xiaoyu (played by Lu Zhengyu) is the only disciple of Baimei's sect, but Baimei has been reluctant to teach him peerless martial arts. However, one day, Baimei was plotted against him. Before he died, he handed over the first volume of the secret book "Peerless Martial Arts".

It was given to Lu Xiaoyu, while the second volume was in the hands of the "Three Saints of the Demon Sect".

The so-called "Three Saints of the Demon Sect" are Junzi Dao, the extinct master Tai and the nameless lonely old man. In order to avenge his master, Lu Xiaoyu practiced martial arts hard every day. Four years later, he embarked on the road of revenge.

After that, he went through many tribulations and finally defeated the Three Saints of the Demon Sect and regained the "Peerless Martial Arts".

However, when he opened the secret book, he saw an unexpected scene.
