Trainee patrol officer Levi inherited a strange Kui pattern jade pendant left by a distant relative. During a late-night patrol, he witnessed a night shift security guard being instantly torn to pieces and annihilated by an invisible monster. In extreme fear, the jade pendant suddenly became hot, and severe pain tore his forehead, and then a cold, inhuman vertical pupil "Eye of Mountains and Seas" suddenly opened!
The neon lights of modern cities twisted and peeled in his eyes, revealing the hidden terrifying truth. The ferocious "mountain and sea beasts" wandered and hunted in the dark alleys; the "people of the mountains and seas" who looked like humans but behaved mysteriously walked indifferently among the crowd. Levi was forced to become the only voyeur of this supernatural hunting ground. The patrol badge could not provide protection. He must rely on this eye that brings endless nightmares to trace the truth in the shadow of the bizarre city.
And the jade pendant that is close to the chest is sending out a silent and blood-thirsty pulse towards the sneaking monster, leading him into a deeper vortex of darkness and the cruel trial of his own destiny.
