My name is Shen Zhao, and I live in a seemingly normal city. This place will seep out mist that shouldn't exist at night, and there are things hidden in the mist - they imitate people and lurk in campuses, office buildings and even homes. There was a great disaster twenty years ago. The "door" sealed underground cracked, and whispers from other worlds began to corrode reality. The country secretly established the "Night Watch" organization to use superpowers to suppress pollution. I am gifted with the ability to see the thread of truth and am the last "successor of enlightenment". Jiang Linxue is the school beauty and the most dangerous obsession. She remembers that she died once ten years ago. We were both acting, she was undercover and so was I. One day the principal called her and me to the office and handed her a bloody contract: Do you want to find out the truth about your parents' death? The price is to sign your name and become a night watchman in either life or death. Under the city, Cthulhu-like tentacles are pulsing slowly. And my sunny smile is just a mask used to hide fear.
