The mental hospital's rule list states five rules: Medication must be taken after three meals a day. The room at the end of the corridor is off limits. After night rounds, patients can move freely on the floor but must not reveal that they are awake. Find the intruder hiding among the medical staff within twenty-four hours.
But the moment Tang Xiaoye opened the list, a line of small blood-red words that only she could see emerged from the paper——
Hidden Rule One: Drugs are protection. The intruder wants you to resist taking your medication.
She is the only one who can see the hidden rules.
The smiling attending doctor said: "You are not a patient. You are the only survivor of the last round of the game."
He was half wrong.
She is not a survivor. She is the builder of this copy system. No. 001.
Five copies, five fragments, five ultimate tortures about "trust", "fear", "truth", "malice" and "sacrifice". Every time she cleared a level, she discovered a backdoor she had left behind at the bottom of the rules—including the modified record that made her sister disappear from the list of survivors.
In the terminal at the top of the tower, her sister had been waiting for her for three years. She must make a choice: break the terminal, all survivors return to reality, and her sister's consciousness dissipates. Or he could stay in the tower, accompany the seventeen-year-old girl, and be forgotten by the world.
