When the ancient secret treasure legend quietly spreads in the tomb robbing world, a fierce competition surrounding the mysterious ancient tomb begins. Zhang Xunlong, the 28-year-old descendant of the ancestral Mojin School Captain, is wearing a black outfit, a cape, and black boots. He has a tall and resolute figure and a resolute face. He and his old friend Li Sanpao are determined to find out the truth. On the one hand, he is to inherit the family skills, and on the other hand, he is looking for his missing grandfather. However, the insidious and cunning "Shadow-faced Fox" Horse-faced King is like a poisonous scorpion in the dark, always coveting the ancient tomb discovered by Zhang Xunlong, trying to seize the opportunity and monopolize the treasure.
Zhang Xunlong and Li Sanpao went deep into the eerie ancient tomb, as if they had stepped into the abyss of death. The traps are like deadly poisonous snakes, ready to swallow them up at any time; the mysterious curse is like invisible shackles, tightly binding their footsteps. Just when they were almost in despair, Professor Chen, an elegant, easy-going and knowledgeable archaeologist, appeared. He originally regarded tomb robbing as an act of destroying cultural relics, but seeing that Zhang Xunlong was not just seeking profit, he decided to cooperate with him and use his tomb robbing experience to solve the mystery of the ancient tomb. This brought a turning point for Zhang Xunlong in his predicament.
However, the road to cooperation has not been smooth sailing. The horse-faced king has set up many conspiracies, like an airtight net, in an attempt to catch Zhang Xunlong and others. Li Sanpao was seriously injured trying to save Zhang Xunlong, and they paid a heavy price.
In this thrilling tomb robbing adventure, when personal interests conflict with the mission of guarding the secrets of the ancient tomb, how should Zhang Xunlong make a choice? How should humans find a balance between greed and protection, destruction and inheritance?
