Eight years ago, a fire engulfed the Lin family, and Ling Chen's parents died. Fortunately, Xuan Jizi rescued him, and he became a disciple and practiced for eight years. Now he comes down from the mountain with Xuanyang Fist and peerless medical skills, vowing to avenge his family. However, as soon as he comes down from the mountain, he is "kidnapped" by Su Qingyuan, a beautiful man who calls himself "senior sister" and rents him together. This direct descendant of the Su family in Longdu not only controls half of the commercial territory of Zhonghai City, but also protects him in every way and has "protecting junior brother" engraved into his DNA.
Childhood sweetheart Shen Weiwei was persecuted by the Wang family, her parents became vegetative, and she was disfigured. Ling Chen came to the rescue, using silver needles to detoxify and remove scars, and even slapped the Wang family in public at the Tianyun Hotel, but unexpectedly involved the shocking conspiracy of the Xia family in Longdu: the fire eight years ago, the mysterious treasure map, the secret realm of Xuanyang where the elixir of longevity can be found, and layers of mist surfaced.
The Xia family used all means to seize the secret realm, sending killers, setting up ambushes, and uniting with the five major families to block it; while Ling Chen practiced Xuanyang Fist to break through the realm, he teamed up with Su Qingyuan to break the situation, from the villa in Zhonghai City to the Xuanyang Temple in Kunlun Mountain, from dealing with mercenary raids to breaking into the secret realm to fight the guardian beasts.
On his road to decisive revenge, he has his beautiful senior sister side by side, his childhood sweethearts by his side, and the secrets of the secret realm intertwined with family grievances - Ling Chen stands with his fists in hand, not only to protect those around him, but also to uncover the truth of the past and make all enemies pay with blood!
