Zhao Shanhe, a locksmith in the market, accepts special orders with his superb craftsmanship. After opening the ancient box, he awakens the inheritance of Qimen Dunjia Lock Dao. He knows that locks can lock spiritual energy and suppress evil spirits. The secret rooms of old houses in the city are full of spiritual locks of cultivation. From then on, he bid farewell to the ordinary lock-picking business and became a "locked master", specializing in opening spiritual locks for monks, protecting the peace of the city, and starting a legend of urban cultivation.
