Lin Dong, an eighteen-year-old boy, lives in the seemingly peaceful and peaceful Licheng. His father, Lin Beiyang, is a famous martial arts gym owner in the town, and his mother is a virtuous man who manages the family. However, a fire that killed neighbor Lei Heng's wife ten years ago opened a bottomless rift between Lin Lei's family. What was once a baby kiss has become an embarrassing past.
When Lin Dong's childhood sweetheart Lei Shanshan asked for help late at night and began to explore the truth behind the rift between the two families, he accidentally got involved in a huge conspiracy surrounding the rare medicinal material "Blood Poria". The mysterious "Black Evil Sect" forces quietly infiltrated into Licheng and used ruthless methods to target the Lin family many times, and firmly controlled Lei Heng.
The grievances of the past have not yet been resolved, and new crises are approaching like dark clouds. Lin Dong and his father Lin Beiyang were forced to join forces and go deep into the crisis-ridden Wangxian Mountain to break into the "Blood Cave", the secret stronghold of the Black Evil Sect. However, what awaits them is not only ferocious enemies and weird traps, but also a cruel truth that can overturn ten years of knowledge. At the critical moment of life and death, the grudges of the previous generation were settled in the most tragic way, and Lin Dong was also forced to grow rapidly in the tempering of blood and fire.
