Shen Zhui, a down-and-out young man who works in the antique street, is responsible for the secrets of a thousand-year-old family that has made fortunes. When a torn scroll of "The Map of Mountains and Rivers" fell into his hands, the dust-covered door to the dragon's cave burst open. Faced with the thousand-year-old tomb that has been exhausted, the dangerous Zongzi, and the various forces coveting the treasure, Shen Zhui relies on his ancestral dragon-hunting secrets and a pair of eyes that can see through illusions to make his way step by step in the darkness. Others' treasure hunts lead to a narrow escape, but his treasure hunts empty out the entire underground treasure house! "I can get out of this dragon's lair as soon as I come in. As for the things inside... It should naturally change its owner."
