At ten o'clock in the evening, the lights in the main teaching building of Maple Grove Academy were all turned off, and only one window on the second floor was on.

In the student union office, Lin Jiujiu was the only one.

Ok！ That's perfect!

She finally closed the folder and tapped the back of her neck, which was a little sore, and smiled with satisfaction.

Since the beginning of high school, she has served as the student president of Maple Grove Academy, and has hosted two campus open days, which have been very successful, and have even become the school's signature event.

Every year from January to autumn, almost all students are eagerly waiting for the Maple Grove Academy Campus Open Day!

This year, she is about to graduate, and she must hold this year's open day well, so that it will become a legend in the history of Maple Grove Academy just like herself!

Lin Jiujiu stood up, put the folder back on the top of the bookcase, locked it, and pulled it again to make sure that the lock was secure, and then put the key into his schoolbag.

Before the open day, this key will only be kept by her.

The process, projects, and attendees of the event are also kept confidential, and even if it is a media interview, she forbids students to reveal a word!

There is no expectation without secrets, no surprises without expectations, and no legends without surprises!

Now, she has only two big wishes -

First, do a good job of this campus open day!

Second, get that boy named Mu Feng into Fenglin Academy!

After she graduated, Maple Grove Academy still needed an excellent student president.

Now, none of the young masters and daughters on campus can be favored by Lin Jiujiu and be his heir.

And Mu Feng of Mingde High School, although he is a little mysterious, Lin Jiujiu believes in his vision.

He is gentle and weak on the outside, but he is actually very powerful and strong!

If you get him to the Maple Grove Academy, you will definitely be able to continue the glory of the school!

Lin Jiujiu thought about his plan, and when he walked out of the school gate excitedly, the road was already very deserted.

She wanted to take a look at the bus in the palm of her hand to see if there was any bus home, and her hand reached into her trouser pocket and touched it, it was empty.

Hey, what about the phone?

You won't be left in the office and forgotten, right?

Lin Jiujiu smiled bitterly and flicked his head.

That boy named Mu Feng is really amazing.

Just because she thinks about him, she doesn't leak anything, and she even forgot to take her mobile phone!

I had no choice but to go back.

She returned to the student union office, opened the door and entered, and turned on the lights.

As soon as the room lit up, Lin Jiujiu's footsteps stopped, his brows sank, and his eyes suddenly became sharp.

She has been strictly trained by her detective father since she was a child, and with just one glance, she can find that there are at least three places in the office, which are different from when she left!

For example, when she leaves, she must close the windows to prevent heavy rain from pouring in at night.

And the curtains flutter slightly, indicating that the windows are not closed firmly!

The trash can under the window has also been moved...... Half a foot away!

The most obvious is the bookcase with glass doors!

The three-layer shelves, how much information to put in, what they are, and how they are sorted, are all regular.

But now, at least one, two, three...... Right! There are four documents, and the location is wrong!

Just five minutes after she left, someone came in this office again, and opened the bookcase!

And the key is still in the palm of her hand!

Thief!

Thieves have been here!

Perhaps, stay in this office!

Lin Jiujiu's sharp gaze slowly swept ahead.

Where people can be hidden, there are no obvious traces of movement.

So, the most likely place for a thief to hide is-
