Delivery rider Lin Feng is involved in an antique mystery that spans a thousand years in order to save his childhood sweetheart Zhou Xiaoman. Ever since he bravely rescued a child who fell into the water by the Yunlan River, the ancestral dragon-patterned jade pendant around his neck has been showing strange phenomena repeatedly, and he was even chased by a mysterious man in black on a rainy night. In order to solve the mystery of the Blood Jade Pixiu, Lin Feng was forced to step into the undercurrent of Qingtan Lane Antique Street and discovered that the entire street would "come alive" at midnight.
As the investigation deepens, an underground labyrinth map engraved on the back of the jade pendant gradually emerges, pointing to the depths of the Binhai International Financial Center. The sky-high three million life-saving money is just the stepping stone to attend the "Yunfan" treasure appraisal auction. When the green light at the bottom of the river lifts the fishing boat into the sky, Lin Feng finally understands: Grandma's words before her death, "The dragon is about to swim back to the river," actually hide the key to changing the fate of the family.
This adventure that spans reality and history will soon reveal the ultimate secret that a line of treasure appraisers has guarded for thousands of years under the fangs of the bloody Pixiu...
