Lin Yan, a master craftsman from the Ming Dynasty, accidentally traveled to a modern city and was penniless. His only resources were a few "modern antiques" in his luggage and his unique skills. In order to survive in modern society and find the mystery of his return, he was forced to enter the bizarre antique industry. From the confusion of setting up a street stall to becoming a top treasure appraiser and antique master, he has experienced the skyrocketing rise and fall of wealth, the unpredictability of people's hearts, the sweetness and bitterness of love, and the fierce collision of ancient and modern values. The antiquities in his hands are not only priceless, but also affect the greedy eyes of all parties and a palace secret buried by history. In the end, he must make a choice between modern responsibilities, emotions and attachment to his homeland, and uncover the ultimate truth about time travel.
