Former detective Shen Qinglan was involved in a strange world called the "Psychic Examination Room".
Here, the ultimate obsession of mankind is the rule of killing.
Everyone said that she was the sharpest knife in the examination room, rational and cold-blooded, and was born just to pass the test.
Until she met Gu Qingci, a folklore professor who seemed gentle but could see through the nature of the rules at a glance.
· In the midnight subway where resentful spirits are rampant, Shen Qinglan is responsible for violently breaking the situation, but Lu Qingci can whisper its true name.
· In the cursed space with an upside-down mirror image, Shen Qinglan deduced a way out, but Gu Qingci's intuition pointed to the only door to death.
When the coldest ice meets the warmest light, they become the most feared combination in all examination rooms.
But when Shen Qinglan discovered that Gu Qingci seemed to be closely related to the ultimate secret of the world——
Her hand holding the gun wavered for the first time.
"Gu Qingci, are you my way out or my final exam question?"
