"So why didn't I answer her call?"

After figuring all this out, I subconsciously asked a question.

"Because we went to Majia Village to deal with the evil spirits associated with rice dumplings!"

Luo Tianhe said somewhat irritably, then looked at me and continued:

"Have you forgotten? When we came back from Majia Village, Baiyang told us that while we were away, someone called her, and one of the calls was related to this matter. I guess it was that girl who made the call."

Hearing this, Zhang Qiang nodded and said to me:

“That’s right. In this girl’s call log, there are also call messages from your friend Bai Yang. This time she got through, and they talked for about two or three minutes.”

My brain is like mush. I didn't get any rest yesterday, and now I'm doing intense mental work. Even with so many clues, I still can't remember anything.

Seeing my appearance, Luo Tianhe couldn't help but remind me:

"Here's a keyword for you: library!"

Now that things have come to this point, I suddenly remembered.

Bai Yang did tell us at the time that someone had contacted her and said they had encountered a paranormal event.

The woman said she went to the library to look up information, and in a corner, someone handed her a file from behind a bookshelf. But how could someone possibly stand in a corner of the library, behind a bookshelf?

The reason I didn't contact this case at first was because I remembered that the outcome was quite good!

With the ghost's help, the girl found clues from many years ago, which helped the ghost find the murder weapon and bring the killer to justice.

Thinking of this, I couldn't help but look at Zhang Qiang:

"What is this female college student majoring in?"

Upon hearing my question, Zhang Qiang paused for a moment, then replied:

"It seems like he majored in law. If this accident hadn't happened, he probably would have become a lawyer."

It really was her!

Bai Yang didn't say much at the time, but she told us about it as a strange and unusual story when we were chatting later.

The story goes that the girl was looking up information in the old section of the library late at night when she saw a pale hand handing her a scroll through the gap in the bookshelf.

She was terrified at the time, but the thing didn't harm her; it just kept hinting that she should find an old object.

To be precise, it was the murder weapon!

Zhang Wei was quite bold, and being a law student, she couldn't resist her curiosity and the allure of the object, so she actually went to search for it. In the end, she actually found it in an abandoned cabinet in the basement of the library.

It was a rusty paper cutter.

Zhang Qiang, who was standing nearby, realized that the two of us knew something, so he pressed us to tell him what had happened.

So I recounted the story to him.

Luo Tianhe heard me repeat myself, and as if he had grasped something, he said with sharp eyes:

"That's the problem. First, why did the ghost specifically target Zhang? There are so many people in the library every day; she wasn't the first one to want to investigate that case!"

"After all, it's a long-standing unsolved case, and every law student wants to solve it to show off their exceptional intelligence."

"And that is precisely why the school put this file here."

"Secondly, how could it be so sure that the murder weapon was still in the library, and even know its exact location? Why didn't it go and get it itself, and instead had Zhang Wei help it find it?"

"Third, once the murder weapon is found, will the ghost be satisfied and Zhang Wei safe? Now it seems that obviously not. Zhang Wei was murdered, and even her head has disappeared!"

Zhang Qiang, who was listening in, immediately grasped the key point:

"Where is that box cutter now? Was it handed over as evidence in an old case, or...?"

"Bai Yang mentioned it briefly," I replied.

"It seems that after the girl found it, she originally wanted to call the police, after all, it was an old case from many years ago. But the ghost seemed to only want to find the murder weapon to rest in peace. The girl may have thought that the police procedure was complicated, so she followed the ghost's instructions, put the knife back where it was, or disposed of it herself."

When Bai Yang told me the story, I just thought it was a strange tale about helping ghosts for fun, and I didn't delve into the details at all!

So much so that I didn't pay attention to the contradictions in what Bai Yang said at the time.

"Put it back where it was? Or dispose of it?"

Zhang Qiang frowned.

"So, she didn't call the police?"

Hearing this, I felt a bit helpless. Bai Yang was just rambling on, and we just listened to it for fun. Who paid much attention to it?

“I remember when Bai Yang first told us about it, he seemed to have called the police and said that he found the murder weapon with the help of the police.”

"But in the second version, for some reason, it completely changed. It became that Zhang Wei searched for it herself, and the police were not involved at all."

Luo Tianhe tried hard to recall and then said.

I nodded; it was indeed just as Luo Tianhe had said.

"Didn't you notice something was wrong back then, but didn't you ask any questions?"

Zhang Qiang looked incredulous, completely baffled as to what we were thinking.

I shrugged helplessly and explained:

“The situation is a bit complicated. We went to a very far place without her. We thought she was just trying to get our attention by telling us ghost stories.”

"Isn't that how young girls are? So the inconsistencies didn't bother us."

Zhang Qiang was so angry that he gritted his teeth.

But there's no point in pursuing the matter further, especially since our actions were probably the same as most normal people's.

"Go to the library immediately!" Zhang Qiang suddenly stood up and said rapidly.

"Find out the whereabouts of that paper cutter, and retrieve the surveillance footage of Zhang Wei entering and leaving the library, especially going to the underground storage room!"

Zhang Qiang instructed his subordinates to check the surveillance footage, and then immediately drove us to the city library.

Zhang Wei didn't do her research in the university library, since most university libraries are actually study rooms.

This is my first time visiting the city library. The library is huge, but it seems a bit gloomy to me.

I wonder if it's because of the library's rather dark brown walls.

We were received by the deputy curator, a middle-aged man surnamed Li. When he learned that our purpose was related to a murder case, he was very cooperative.

"Zhang Wei, alas, what a pity. She does come here often, especially to the legal documents section and the old newspapers section."

"But I heard she died in a car accident, how could it be related to a murder case? This case has caused quite a stir, and I've heard some rumors that her family is particularly dissatisfied with your police station?"

The middle-aged man surnamed Li was a bit gossipy, which annoyed Zhang Qiang.

I looked at the information Zhang Qiang had sent us on my phone.

This man surnamed Li seems quite capable, but he only became a deputy curator, probably largely because of his gossipy nature.
