An Qiqi was still busy cleaning up the house with Wang Shulin and Cheng Shaoqing.

The toothbrushes and bedding used by Xu Lingfei and others before were all thrown away by them, but there were also laptops and other entertainment facilities, but An Qiqi was reluctant to throw them away, so they all left.

It can only be said that the house is good when it is big, and it can store a lot of good things.

At this moment, the three of them also came to the study, which was full of all kinds of materials, which was about the place where Xu Lingfei and them used to review.

There are piles of books everywhere, and they seem to be small mountain bags.

"I didn't expect that Xu Lingfei has a lot of review materials."

The three of them were also a little surprised, thinking about the bully who could bend and stretch, it didn't look like a material that would sit down and read a book at all.

But Angel Qi flipped through a few copies casually, and they were all blank.

Blank volumes, blank books, blank notes.

Although there are a lot of things, there are no traces of hard work.

Looking at the furnishings and atmosphere in this study, it is like a kind of camouflage, as if it is hiding something real......

Thinking of this, Angel already felt that things were a little weird, who did Xu Lingfei show at home doing this kind of superficial work?

And when I occupied his house just now, I also felt that he didn't seem to be normal, and when he left, he glanced into the house meaningfully, obviously reluctant to give up something.

And the position that Xu Lingfei was looking at at at that time...... This must be the study room, right?

So while the two boys were going upstairs, Angel looked carefully in the study again.

According to her habit of being an agent, this kind of superficial situation must be to hide some real insider!

Sure enough, the floor under one of the tables was hollow, and Angel discovered the dark grid.

Angel was a little surprised, a student's residence actually has a secret grid, is it so high-end?

Looks like there's something big going on inside.

Opening the dark compartment, Angel took out a small wooden box from inside, red sandalwood, the size of this box, just enough to fit something the size of A4.

Well...... What could it be?

Is it Xu Lingfei's unsightly little yellow 1 book?

Angel opened the wooden box as she thought about it, and then her face suddenly turned embarrassed.

I saw a rolled piece of paper in the box, and when I opened it, it was full of exercises!

It turned out to be a roll?

What are you kidding, such a hidden secret is hiding a roll, or a roll.

Has Xu Lingfei been obsessed with learning to this extent?

Angel Qi looked at the paper in surprise, but this paper didn't look special, it was just an ordinary high school exam paper.

An ordinary test paper still needs to be hidden? Definitely not.

Could it be that this test paper really has some special secrets?

Angel couldn't think of it for a long time, so she simply took out the test paper, folded it and put it in her pocket, then thought about it, stuffed another thing in the box, and put it back in the dark compartment again.

After doing all this, Angel swaggered out.

Let's go back and study this paper carefully, what's so strange about Xu Lingfei's hidden secret, maybe it's the exam question of this ranking exam!

Angel just thought about it casually, but when her thoughts ran here, she also stopped suddenly, and her big eyes blinked.

Belch...... Feel like you've accidentally figured out some big secret?!
