Jiang Cheng turned to look at Gao Yan. "What's wrong, Mr. Gao? Don't you trust me, Jiang?"

Gao Yan chuckled awkwardly, his expression unnatural as he said, "That's not it at all. I'm just worried about Brother Jiang's safety. After all, we need to be wary of this Yuan Xiaoyi."

"You weren't saying that just now!" The fatty's face flushed red, and he rolled up his sleeves, showing that he had been angry earlier.

"Hehe, it's all a misunderstanding."

"Alright, don't argue." Shen Mengyun looked worried, then turned to Jiang Cheng. "Mr. Jiang, what did Yuan Xiaoyi say?"

Hearing this, Gao Yan and the fatty, Huai Yi, fell silent. Everyone looked at Jiang Cheng in unison.

Jiang Cheng glanced at Gao Yan, who avoided his gaze somewhat guiltily.

"Where's Wang Qi?" After a moment, Jiang Cheng asked.

There was something strange about this guy, so Jiang Cheng was paying special attention to him.

"He disappeared after class. We waited for him for a while, and almost everyone else had left, but we didn't see him," Huai Yi explained.

Shen Mengyun said, "I called him, and he said he was bored and wanted to wander around the school."

Judging from Shen Mengyun's expression, she was also troubled by this loner.

After thinking it over, Jiang Cheng used the shortest possible words to tell everyone the information he had obtained from Yuan Xiaoyi.

This time, there was relatively little information about the library, and Jiang Cheng himself was puzzled by many things. Gao Yan frowned slightly as he listened, obviously suspecting that Jiang Cheng was hiding some of it.

Jiang Cheng didn't bother to explain.

Wang Qi didn't appear until after lunch. In the afternoon, everyone attended classes as usual, except for Jiang Cheng, who was called to Professor Wu's office.

Professor Wu seemed to value Jiang Cheng very much, and he painstakingly lectured him about many important principles, telling him not to waste his time, to strictly discipline himself, and to devote his limited energy to his studies.

It got dark earlier than usual today. It wasn't even 4 o'clock, and the students had already finished dinner and were leaving the school cafeteria.

Jiang Cheng and his group were walking towards the dormitory, talking as they went.

Shen Mengyun looked at the darkness around them, and a worried expression appeared on her face. "It's getting dark earlier and earlier."

"And it's getting light later and later in the morning," the fatty added.

"I guess in a few days, the daytime will disappear completely, and the whole world will enter eternal night." Huai Yi looked at the rows of streetlights on both sides of the road, their dim yellow light giving a feeling of being at the end of the road, making the atmosphere in the group even more oppressive.

Based on the current clues, the Mind-Devouring Demon (shi xin mo) has not attacked them during the day, it seems to only be able to act at night.

But this balance is likely to be broken after the whole world falls into eternal night.

The Mind-Devouring Demon will no longer be restricted and will launch a massacre against the remaining people.

Of course, that's assuming that any of them can survive until then.

Wang Qi raised his head and squinted at the sky.

The sky was like a mass of ink that couldn't be spread out, not just black, but... a kind of indescribable turbidity.

"Three days," Wang Qi said softly.

The fatty turned to look at him, asking in confusion, "What three days?"

"In three days, the daytime will disappear." Wang Qi seemed to be particularly patient with the fatty, and his eyes when he looked at the fatty were also different from when he looked at others.

Jiang Cheng had noticed this at the abandoned playground.

"Three days..." Gao Yan's eyes suddenly paused, as if he had thought of something. "We still have three places left to go: the school library, the sculpture hall, and the swimming pool. The three missing girls are hidden in these three places."

"Have you thought about it? The Mind-Devouring Demon (shi xin mo) followed us in the medical building and the abandoned playground, but it didn't attack us," Jiang Cheng pointed out. "Its only attacks were aimed at preventing us from finding clues, not killing us. Why is that?"

Come to think of it, of the two teammates who died, Shi Xiaoya was killed by the ghost in the medical building's urban legend, and Wen Liangshan died at the hands of the red-clothed ghost in the abandoned playground.

"Because the Mind-Devouring Demon (shi xin mo) can't directly kill us," Wang Qi said, very naturally. "All it can do is follow us and use us to get rid of the girls hidden in the urban legends."

"Every time a girl is killed, the world's daytime will be shortened. When it kills all five girls hidden in the urban legends, the daytime will disappear, and then..." Wang Qi tilted his head with interest, staring at Jiang Cheng. "We'll be the ones to die."

"To be precise, it'll be the ones of us who are still left at that time," Jiang Cheng calmly added.

"That's right."

The two people's conversation opened up new ideas for everyone, and the faces of several people became colorful.

In this mission, the sources of danger are mainly divided into two parts.

One part is the ghosts in the urban legends.

The remaining part is the Mind-Devouring Demon (shi xin mo).

But it is unlikely that the ghosts in the urban legends can wipe them out, and once the girls hidden in the five urban legends are found by the Mind-Devouring Demon (shi xin mo) and killed, the Mind-Devouring Demon (shi xin mo) will become the ultimate unsolvable terror, reaping all the survivors.

"What do we do next?" the fatty asked cautiously.

Whether it's the Mind-Devouring Demon (shi xin mo) or these campus urban legends, it's all the same to the fatty, they can all easily kill him.

"The notebook in the activity center warehouse, remember?"

Shen Mengyun nodded, her eyes also becoming strange as she looked at Jiang Cheng. "Are you saying that if we go to the library today, we'll find the book that corresponds to the number?"

"That book was left by the owner of the museum. Based on the clues we know so far, it should contain the origin of the Mind-Devouring Demon (shi xin mo) and how to deal with it," Jiang Cheng replied.

After returning to the dormitory, everyone hurried to rest, preparing for the night's action.

At exactly 11 o'clock, everyone quietly sneaked out of the old dormitory building and gathered under a crooked-neck tree not far away.

Looking back at the direction of the dormitory building, only a vague outline remained in the dark night. "Let's go."

Led by Jiang Cheng, the group headed towards the library.

Jiangtan University at night was eerily quiet. Although it wasn't the first time they had known this, walking on the dark and silent campus still made them feel uneasy.

Some of the buildings in the distance had lights on in twos and threes, but looking at them for a long time didn't bring comfort, but instead felt even more strange.

Like eyes that had been opened, watching them.

Watching them step by step into the abyss...

Just like Yuan Xiaoyi described, the library was pitch black at night, and there wasn't even a lamp left on to illuminate the front of the door.

But when they got closer, everyone noticed something strange.

The library door was made of glass, and through the glass, they could see a blackboard standing by the door inside.
