The old lady's words sounded illogical, but they actually revealed too much information.

First of all, before graduation, Cheng Yun went home to find a passbook, which means that the time point was after the start of the second semester of her senior year.

There were 300,000 yuan on the passbook, according to the old lady, Cheng Yun took it all, and did not send the passbook back after that.

Even if you need to collect some materials for your graduation project, it won't cost as much as 300,000 yuan.

Obviously, this reason was made up by Cheng Yun to deceive her grandmother.

But why did she deceive people?

Where did the 300,000 go to be spent?

With such a question, Chen Aiqing looked at the old lady and continued to play the role of "Cheng Yun": "Grandma, don't worry, I haven't moved the money, I haven't moved a cent, it's just about to graduate, there may be some places that cost money, so take it first, and when you graduate, find a job, everything will be stable, you can put it up again and keep it for me, okay?" ”

When the old lady heard her say this, she smiled: "I'm not worried about the money, I'm worried about you, my poor child, my parents went early, and I am still dragging an old woman by my side, I can't help anything, and I have to burden you at every turn......"

Chen Aiqing hurriedly comforted: "Grandma, what are you talking about, you are my grandmother, and it is right to take care of you." ”

As she spoke, she lowered her eyes, not daring to meet the old lady's gaze.

Grandmother, if Cheng Yun really became like that because of Chen Chen, then Chen Chen must be responsible for her death.

And as Chen Chen's own sister, I really can't think of any way to compensate for it except to take good care of you.

But for now, we have to get the box out.

Thinking like this, Chen Aiqing stood up: "Grandma, you watch TV for a while, I forgot my phone in the room, I'll take it down." ”

The old lady seemed to have forgotten what she had just said, and the trace of sadness that was revealed was lost in an instant as soon as she said it.

I saw her eyes staring at the TV, as if she was integrated into the plot of the TV series, and nodded "mmmmmm".

Walking back to the bedroom, Chen Aiqing leaned down again.

This time, she stretched out her arm, grabbed the handle on the side, and dragged the box out in one fell swoop.

It hadn't been cleaned for a long time, and the box was covered with a thick layer of dust.

Chen Aiqing took two tissues from the bedside table and wiped the surface of the box before opening it.

On the top layer is the death certificate issued by the hospital, as well as some supporting documents that Chen Aiqing later went to the police station where Cheng Yun's household registration is located.

When you take away these documents, you will see a student ID, a library card, and a cafeteria meal card with a cartoon card holder.

Chen Aiqing took a deep breath and continued to flip through the things below.

The diary with a light green hard-shell cover, when she first sorted things out, she roughly flipped through it, and there was nothing suspicious.

Cheng Yun is a very persistent person, unlike her, who once made up her mind to keep a diary and keep an account book, but after three days of fishing and two days of drying nets, she gave up after a few days.

Although only one or two sentences were recorded under each date, after a long time, a thick diary was also densely written.

Just when Chen Aiqing put down the diary and was about to go through the things that followed, suddenly there was a date recorded on the page, which attracted her attention.

In the past few days from March 5th to 7th, Cheng Yun did not keep a diary.
