Locksmith Qin Feng inherited his ancestral business. When he opened the copper lock of a century-old house, he accidentally discovered that there was a mysterious formation engraved in the lock core. With the help of the ancestral "formation-breaking key", he unlocked the seal core and obtained a cultivation treasure. Only then did he realize that the Qin family's lock-opening technique was actually a branch of the ancient "formation-breaking technique". From then on, he used the lock shop as a cover and relied on his lockpicking skills to quietly unlock the dusty secrets of cultivation in the corners of the modern city, and stepped into the mysterious world hidden in the secular world.
