Actually, the police had looked at the room before and didn't find anything useful. After looking around, Su He focused her attention on the desk.

"The books here are all ones that Ya Ya likes to read; she just loves reading storybooks."

Su He glanced at the book titles; they were all children's books from that era, such as "Red Tassels on the Battlefield" and "The Story of Painting Spring," some even with color illustrations. A complete set would be quite expensive, but the books she had here were very complete, which showed how much they doted on their daughter.

Su He casually picked up a book and flipped through it, thinking that someone must have seen these before and that no one would notice anything.

But suddenly I felt a flash in my eyes as if I saw some words.

So I quickly flipped through it again, but this time I didn't see it.

However, Su He didn't think she had misread it, so she quickly opened the book and started flipping through the pages one by one.

Fortunately, the book wasn't thick, and when she turned to page 18, she saw a sentence.

It is a sentence written with a fountain pen.

"He's so scary!"

Upon seeing the content, Su He's pupils immediately contracted.

Could this sentence have been left by Xu Jingya?

Song Xiangyu, who was standing nearby, also saw Su He's actions and walked over curiously. Then she saw the words on the book.

He immediately snatched the book from her hands.

Then he touched it with trembling hands.

Tears welled up in her eyes instantly. "What happened? When did Ya Ya write this? I didn't know!"

Upon hearing this, Su He immediately became serious. "Are you sure this is Xu Jingya's handwriting?"

"It's Ya Ya, it's her! When did she write this? Who is she afraid of? Why didn't I know about this?!?"

In the end, Song Xiangyu shouted it out, seemingly annoyed and regretful.

The noise was so loud that even Xu Qinghuan outside heard it, and he quickly brought his daughter inside to check on her.

"What happened?"

When he came in, he was startled to see his wife crying so hard. He wanted to go forward and support her, but it was inconvenient because he was holding his daughter.

Then he looked at Su He with a suspicious gaze.

Seeing this, Su He sighed and explained, "I saw her writing in Xu Jingya's book, the content of which..."

Su He didn't say anything; seeing Song Xiangyu crying so sadly, she didn't know how to comfort her.

Actually, she knew why she was like this. After all, Xu's parents always cared about their daughter, but they never expected that their daughter would have someone she was so afraid of behind their backs. Did that mean they didn't care enough?

She felt even more regretful that if they had been more concerned at the time, her daughter might have told them and wouldn't have died.

Of course, it's no use saying all this now, but it's still very sad to suddenly know the truth.

Upon hearing her words, Xu Qinghuan looked down and saw the book his wife was clutching tightly and the words on it.

His pupils immediately contracted, and his eyes instantly turned red.

He could imagine how guilty his wife would feel seeing these things, and not just his wife, but he felt the same way!

But now that the damage has been done, they can't change it. All they can do is try their best to find out the truth and avenge their daughter!

So Xu Qinghuan forced himself to stay alert and looked at Su He, asking, "How did Officer Su discover this? Is this all there is?"

Su He shook her head. "I just randomly flipped to it. It was a matter of luck. Maybe I just happened to be on that page. As for whether there are any more, I don't know. Did the police check these books when the incident happened?"

"I took a quick look and didn't notice anything, so I didn't pay much attention."

Su He nodded, "Then it's probably something we overlooked back then. We need to check it again now. Could you please bring over all the books that Xu Jingya has read? I need to check them page by page."

"Okay, I'll help you."
