Deep in the maze-like underground of Chungking Tower, sleeping is not the remains of steel and concrete, but an organ that is still crawling.
A Ming, a down-and-out young man with a medical dream but failed in many attempts, rented a subdivided room on the third floor of Chungking Tower in order to survive and found a part-time job delivering linens in the hotel laundry room. His life is cut into numbers accurate to the minute: the dripping water on the wall at 60 BPM is the heart rate that wakes him up; the abnormal sound in the elevator at 01:44 is the signal for the mycelium to wake up; and the blood-red "△" on the calendar behind the door is quietly connecting to form a death hexagon that traps him.
He soon discovered that strange, unexplainable bacterial plaques began to appear on the linens he transported. They only grew on fabrics that were washed and dried at 1:44 in the morning. Following the clues, he stepped step by step into the deeper forbidden areas of the building - the B4 floor that "does not exist" in the official drawings. Here, there was once a painless clinic called "Benevolence", but now it has been transformed into an inverted operating room that violates the laws of physics, an eternal nightmare with inhuman nurses wandering around.
When scientific knowledge collapsed in the face of supernatural reality, Amin discovered that terrible changes began to occur inside his body. The triangular key in his hand can not only open the forbidden door to the truth, but it may also become the murder weapon that initiates his own sacrifice ceremony. He must solve the death mystery entangled with the clinic's bloody past, mysterious symbols and urban legends before the next new moon night.
Otherwise, he will cease to be a seeker of the truth;
It is this living building, the next nourishment to be "digested".
