Jiangcheng pursed his lips, his tone tinged with sadness. He exhaled and said, "I don't want the tragedy to repeat itself."

This scene rekindled hope in Yuan Xiaoyi's eyes, and her pale face even regained a hint of color. She recalled, "Senior, the school library and the abandoned playground, like the medical building, are all recognized as some of the most ominous places on campus."

"Xiao Hui often went to the library to read, so she knew more about it than we did. She would privately tell us things about it."

"Compared to other libraries, Jiangtan University's school library has many strange aspects." Yuan Xiaoyi hesitated for a moment, then continued, "For example, it closes at 9 p.m., and all teachers and students must leave."

"After everyone leaves, the library doesn't leave any lights on at night, nor does anyone stay on duty. I heard that even the school security guards avoid patrolling there at night."

Mentioning the night patrol, Jiangcheng suddenly thought of the two security guards he had encountered outside the abandoned playground last night.

The security guards still dared to glance at the abandoned playground, but they avoided the school library at night.

By comparing the two, Jiangcheng gained a new understanding of the library's terrifying nature.

After all, this was also the origin of the Devouring Heart Demon.

Yuan Xiaoyi didn't seem to think so much, and just continued, "Of course, these can only be said to be strange, but... but the fact that the fourth floor of the library is empty is very bizarre."

Perhaps worried that Jiangcheng wouldn't understand, Yuan Xiaoyi reorganized her words and explained, "Senior, you may not know, but our school's library looks big, but the interior space is very unreasonable. It can't accommodate many students."

"It's usually fine, but when it comes to exam week or other important times, there simply aren't enough seats."

"Our students, and some teachers, have complained to the school many times, but the school always finds excuses to prevaricate."

"They say that the building is too old, the waterproofing on the fourth floor is not good, and it needs to be repaired before it can be used. They already have plans and ask us to wait patiently for the arrangements."

"But..." Yuan Xiaoyi looked up, her eyes filled with doubt as she looked at Jiangcheng, "A teacher once told us privately that since she came to this school, the school has been saying that it would renovate the fourth floor of the library, but it has been delayed until now without any action."

"By the way," Yuan Xiaoyi lowered her voice, "this teacher graduated from our university more than 10 years ago."

Jiangcheng had been to the school library, and the interior space layout was indeed strange. According to the story told by Curator Zhou, it was arranged by the Night Watchers.

Jiangcheng believed that what Curator Zhou said was true.

And the purpose of such an arrangement was naturally related to the Devouring Heart Demon.

Jiangcheng had already thought through the whole story in his mind, but he didn't show anything on his face. He just nodded and said, "Xiaoyi, are you saying that there's something wrong with this library?"

The angle of his question was just right, not delving into any particular detail, otherwise "Yuan Xiaoyi" would easily see through his disguise.

"Yes, Senior. If it were just a simple leak, how could it be delayed for so long? After all, repairing the fourth floor of the library would also be beneficial to the school."

"Then one day, Xiao Hui came back from the library and found us, mysteriously telling us that she finally knew why the fourth floor of the library had been abandoned until now."

"It wasn't because the school said the building was old or that there was a leak, but because of a case many years ago."

Hearing the word "case," Jiangcheng sat up straight subconsciously. The main event he had been waiting for had finally arrived.

After dragging things out with Yuan Xiaoyi for so long, the ominous feeling in his heart became more and more obvious. If he continued to delay, something might happen.

"What case?" Jiangcheng tilted his head and asked naturally.

"It was a long time ago, dating back decades, to when Jiangtan University was first established," Yuan Xiaoyi recalled.

"The building existed before the school was built, but it wasn't a library then. As for what it was, Xiao Hui said she didn't know."

"Anyway, later the building was assigned to the school for use, and the school renovated and rebuilt it into the library it is today on the original foundation."

"Oh, right, Xiao Hui also said that the library had a fourth floor back then."

"I mean, the fourth floor was usable," Yuan Xiaoyi emphasized.

"It's just that the location wasn't very convenient and the lighting wasn't good, so it was used to store some unpopular books, and very few people came here to borrow them."

It seemed that the word "unpopular" gave Jiangcheng a hint. He looked at Yuan Xiaoyi with a confused expression and asked naturally, "What kind of books were they? Do you know?"

"It was..." Yuan Xiaoyi recalled, "It seemed like there was history, but according to Xiao Hui, it wasn't official history, but some unverifiable unofficial history. There were also some foreign language books, with black covers, that looked very thick and heavy."

Frowning, Yuan Xiaoyi seemed to be searching in her mind, "Xiao Hui mentioned it to me, but I... but I can't quite remember."

At the same time as hearing these words, Jiangcheng suddenly felt a chill, as if a cold steel knife was scraping against his skin.

The next second, following the direction of that cold feeling, Jiangcheng noticed that it was the corner of Yuan Xiaoyi's eye!

She was secretly observing him.

No.

She was testing him!

Crap...

A chill ran through him, and Jiangcheng instantly knew where he had revealed himself.

It was the books.

The other party only casually mentioned that the fourth floor of the library stored some unpopular books, but he reacted like a cat that smelled fish.

Unless... he knew something beforehand related to the books, he wouldn't have reacted like that.

Now that things had come to this, Jiangcheng certainly wouldn't be foolish enough to think about explaining or making up for it. After a moment, Jiangcheng gave his answer.

He turned his head and looked at Yuan Xiaoyi with a puzzled expression, a hint of barely suppressed anxiety on his face, and urged her, "Xiaoyi, now is not the time to be mysterious. Think carefully, what kind of books were on the fourth floor of the library?"

"Anything Xiao Hui mentioned, you must tell me, tell me completely. Maybe one sentence could save a life."

After saying these words, Jiangcheng seemed to be in a bad mood, his tone weakened, and he even showed a hint of regret, "Xiao Lin and Xiao Ting are already gone. A large part of the reason is that the preparation work was not done well. If... if I had asked more questions at the time, maybe they wouldn't have died."

"Senior," Yuan Xiaoyi seemed to have suddenly remembered something, "I remember now. Xiao Hui said that there was a sign hanging on the bookshelf where the foreign language books were stored on the fourth floor, and it was also in a foreign language."

"After translating it, it seemed..." she paused, "it seemed to be about... occultism."
