Chen Xiaochuan, a poor antiques apprentice, has a huge debt of 300,000 yuan and is trapped in a dilapidated old shop. In a desperate situation, he accidentally awakens the power of story echo - whenever he touches an ancient object with his fingertips, he can listen to the dust-laden past and glimpse the hidden secrets of the old owner's past.
In order to repay a huge debt, he was forced to take over a series of bizarre treasure appraisal commissions. Since then, he has entered the underground antique black market where fish and dragons are mixed, and has been gradually involved in the center of the whirlpool of thousands of years of antiquities. His innate superpower is the only core key to unlocking the ultimate truth of the ancient heavenly lock. Lin Wanying, a top cultural relic restorer with a mysterious life experience, is an orphan of an archaeological team and possesses the lost spirit of Wen Yu, who can sense the flow of spiritual energy in ancient objects. In order to find the bronze compass left behind by her missing father, she took the initiative to approach Chen Xiaochuan. It was originally a trial cooperation to get what they needed, but she was gradually moved by the purity and tenacity in his bones, and became his most reliable confidant and ally in the ups and downs of the antique conspiracy.
Zhou Ye, the man behind the black market in the city, was once a top treasure appraisal expert in the industry. Because of his obsession with believing that things are more valuable than people, he secretly controlled the undercurrent of cultural relic smuggling. He pretended to help Chen Xiaochuan, but in fact he planned to use his superpower to break the heavenly lock. He even secretly hid half a jade seal with the power to reverse time and space in his hand, and his ambition was hidden in the abyss. The mysterious gatekeeper of the antique city, Lao Huai, is half-blind and taciturn. In fact, he is a descendant of the royal craftsmen of the previous dynasty. He is born with the ability to understand the voices of artifacts. He cleans the broken ancient mirror every day, and this bronze mirror is the original carrier of the story's echo power. He silently and secretly guided Chen Xiaochuan, just waiting for the destined person to repair the Tiangong Lock and rescue the soul of his granddaughter trapped in the ancient artifacts.
