Watching at Midnight, Hiding Shadows in the Dark

At one forty-seven in the morning, there was only the cold white light of the mobile phone tearing through the darkness in the rental house. Lin Yan thought it was just an ordinary night alone, until a strange handwriting appeared out of thin air on the lock screen - that unknown existence accurately understood his sleeping posture, body feeling, and even all his secret movements. It doesn't break into a room, but it's everywhere. What's even more frightening is that Lin Yan found that his body began to undergo strange changes, and he could "perceive" things hidden in the shadows. Under the neon lights of the city, the darkness is never empty. When the invisible surveillance turned into a life-threatening pursuit, Lin Yan had no way out and could only bite the bullet and step into this silent hunt.
