Qingyun Lane in Nandu City hides too many secrets. For example, Chen Yan, the young owner of Chenji Grocery Store, appears to be an ordinary shopkeeper who guards peach trees and charms, but in fact he is the last generation successor of Maoshan Shu.
When under the reinforced concrete of the modern city, ancient space cracks quietly opened, strange shadows from another world wandered through the mirror, and the residual sound of the old stage echoed in the office building, Chen Yan's peaceful life was completely broken. Holding the mahogany sword left behind by his master, he not only wanted to cover up traces of the supernatural in the flashing neon lights and prevent the ferocious forces from the outside world from pouring into the world, but he also had to follow the guidance of the cracks and step into one bizarre plane after another - where there is a world of cultivation where spiritual energy is revived, there is a demonic realm where technology and magic are intertwined, there is also the lost inheritance of Maoshan Shu and the buried past.
From the deep alleys of the city to the sky of another world, he is a guardian walking on the edge of two worlds and a lone traveler in pursuit of the truth. But what overflows from the cracks, in addition to danger and disputes, seems to be a secret related to his life experience that has been sealed by time.
When modern science meets ancient magic, when the fireworks of the human world collide with the strangeness of the other world, this adventure that begins in Qingyun Lane will eventually reveal all the answers about "world" and "people".
