We guard the night until dawn.
But what if light itself is the deepest lie?
The Night Watchers have been hiding in the darkness for generations, fighting bloody battles with the "dark tribe" that erodes reality.
Lin Che, an ordinary newcomer in District 3, awakened the "forbidden blood" that frightened the dark tribe in a desperate situation.
This talent made him a hope, and also revealed the cruel life experience of his "Experimental Subject 007".
The butcher's knife in District 1 has been raised, and the former companions have become cold monitors.
When the truth of the organization, the origin of the Dark Tribe, and one's own destiny are intertwined,
Lin Che must make a choice before this chess game comes to fruition——
Should it become a destroyed anomaly, or... Redefine what a guardian is.
My blood is the poison that the dark tribe fears most.
My file is the organization's top secret.
My code name: Experimental Subject 007.
My new mission: find out what I am before I'm killed by one of my own.
