Under the glory of Longzhou City, there is a ruins buried for thousands of years.
The demolition of old cities, the excavation of subways, and the laying of foundations for high-rise buildings. Every time the ground is broken, taboos sleeping underground are awakened.
They do not commit crimes directly, but use rules as a cage and obsession as a blade.
Tampering with memories, creating loops, amplifying the darkness of people's hearts, causing ordinary people to collapse and disappear without even realizing it.
Chen Yan, a restorer of old objects, was born with the ability to see reverberations, obsessions and shadows of rules.
His parents died young and his grandfather disappeared. A bronze lock dragged him into the darkest secret of the city.
He has no magical powers, no magic, only his eyes, hands, and an extremely calm heart.
Observe the rules, break the cycle, calm the residual thoughts, and suppress the Yin Ruins.
Su Qinghe, the female police officer of the cold case team, only believes in evidence and does not believe in strange forces.
From the initial confrontation and suspicion, to the only companion willing to step into the dark night with him.
The two use reason to fight against absurdity, and human hearts to fight against the unknown.
The Night's Watch lineage is divided, the good ones are in peace, and the villains are raising tricks.
Longzhou is not a city, but a place sealed in ancient times.
And Chen Yan is the key and the last lock.
When the rules collapse, ruins spread, and the world falls into a long night.
What he wants to keep is never an old alley, but the sobriety and survival of the entire city.
