Xiaoxiao's insomnia has been going on for almost a month. During the day, she sat on the bed and looked at Xiao Zhou and Xiao Yao with misty eyes and slow movements, and looked at Lingzi's empty bed for a while, feeling that time seemed to be frozen. She couldn't go anywhere but her dorm, she couldn't do anything in it, and she knew that there must be a few pairs of despicable eyes watching her every move in some dark corner. For more and more time, Xiaoxiao even wished to be disappeared immediately after her last adventure, but nothing she had expected happened. At night, Xiao Zhou and Xiao Yao and Yi were sleeping on their backs on the bed, and if it weren't for the slow breathing that drove their chests to rise and fall, Xiaoxiao would feel that she was staying with two cold dead bodies. She was conscious as she lay on the bed tossing and turning to torture herself, and she even began to regret that she hadn't eaten the food laced with unknown drugs in the infirmary, "When will these days end?" Xiaoxiao thought desperately as she looked at the darkness on the ceiling above her head, but when she wanted to cry uncontrollably, she found that her tears had already dried up unconsciously.

At three o'clock in the morning, Xiaoxiao climbed down from the bed to get the cup on the windowsill, which was the milk she had to prepare for herself at this time every day. After many experiments, Xiaoxiao found that only by drinking a glass of milk at 3 a.m. could she sleep in a daze for an hour before dawn, and this hour was a life-saving hour.

"I really don't want to die quietly in torment. Xiaoxiao said to herself while picking up the cup on the windowsill.

Just when the mouth of the cup was about to touch Xiaoxiao's lips, Xiaoxiao suddenly found that today's milk was a little different from usual, and there was a layer of blue reflection floating on the surface of the milk, and in that layer of reflection, it seemed to show its own distorted shadow. At first, Xiaoxiao thought that the blue light was a reflection of the night outside the window, but when she turned her back to the window and held the milk in front of her and looked down closely, she realized that the faint blue color was the color of the milk itself. Xiaoxiao turned the cup slowly, the light blue milk gradually became transparent, and she found that her own shadow that appeared in the cup just now was slowly sinking to the bottom of the cup. She held the cup above her head, and finally found a note at the bottom of the cup that had been glued at some point, and there was nothing special on it, only a number: 22.

Xiaoxiao put down the cup and turned to look out the window at the darkness that she was already familiar with in the early hours of the morning, and she kept guessing the meaning of the number in her mind until she remembered Reiko's death.

"Lingzi saw the number 21 when she died, is it just a coincidence?" Xiaoxiao was thinking of this, when suddenly a thin hand stretched out from her left side, which was holding the glass of milk she had just put down, and at this time the cold glass had been attached to the left side of her face.

Xiaoxiao was too weak to tremble, she just wanted to turn her head to see who the person behind her was, but from the right side stretched out another hand, and five fingers like dead branches slowly clasped her mouth.

Xiaoxiao clenched her teeth with the last of her strength, her hands naturally hanging down at her sides, but she could no longer obey her domination.

"Drink it. The voice in my ears was dry and harsh, revealing a terrible poison.

The hand that was clasped on Xiaoxiao's mouth increased its strength, and finally Xiaoxiao couldn't bear the pain and opened her mouth. Holding up the glass of blue milk with her other hand, Xiaoxiao saw with a pair of wide eyes that the cup was tilting to her lips until a cold, strange-tasting liquid poured inexorably into her esophagus. Xiaoxiao's stomach twitched in pain at first, and then it became a fragile container exposed to the night, Xiaoxiao could even hear the sound of milk splashing in her stomach, and she felt like a human skin bag.
