Qin Chenchen's head exploded, and she hurriedly ran to the door, twisting the doorknob vigorously.

Sure enough, it couldn't be opened.

The door is locked from the outside!

How so? Who locks the door?

Qin Chenchen slammed the door vigorously with his hand, and shouted loudly: "Is there anyone?" Open the door! ”

She was greeted by the fading laughter.

Qin Chenchen sat on the ground decadently, stunned for a while.

Why? She just found a drawing and let people lock it here.

Alas! It's bad luck. It's a pity she doesn't have a cell phone, so she can't call for help!

Now what?

"Come on, help me, I'm locked inside. Are there any cuties passing by outside? ”

Half an hour later, Qin Chenchen's hands were swollen, and her voice was hoarse, but no one responded to her.

She looked out the window at the dim light of the sky: it was getting dark.

"Well, what to do? Could it be that I'm going to spend the night here tonight? ”

Qin Chenchen was tired and thirsty, so he had to take a disposable paper cup from the office, take a glass of water, and then stand by the window and look down.

This is the fifth floor! Underneath is a large basketball court. At the end of the school day, there are a lot of boys who gather to play basketball.

Qin Chenchen pondered, should he call for help to the boy playing ball below?

But that's weird, isn't it? When the boy saw it, there was a girl standing at the window on the fifth floor and shouting, maybe he thought it was a nervous disorder.

So, Qin Chenchen is square again!

She returned to the door, as before, squatting in a deliberate manner, sometimes shouting, sometimes banging on the door.

Her classmates, she thought, were waiting for her. If you can't wait for her, you'll definitely come looking for her. So she was saved.

However, Qin Chenchen did a lot of calculations, but he didn't count a little. Her lovely classmates, by chance, missed her.

Just two minutes ago, when she was standing at the window drinking water and thinking about what to do, her classmates had already visited.

Two classmates came.

Student A said at the time: "Could Chenchen have gone back yet?" ”

Student B: "No, I don't. ”

Student A: "But the senior sister of the student council we met just now said that everyone in the student council is off work. The chairman has also returned home from school. ”

Student B: "Let's take a look and make sure." ”

"Okay......"

So, the two classmates came to the fifth floor, and at a glance, the door of the chairman's office was closed, and a lock was added outside.

Classmate A complained: "I'll just say it, Qin Chenchen must have gone home." ”

Student B was also angry: "Really, he didn't say hello to us when he left." It's too much. Let's go home, tomorrow we can't finish the task, we'll put all the blame on her. ”

And then... Qin Chenchen just missed an excellent opportunity to be rescued!

Another half hour passed, and it was already half dark. Qin Chenchen was completely panicked.

"No, it won't. Do I really want to spend the night here? She hurriedly turned on the lights in her office and began to rummage through pen and paper.

She came up with the only solution: write down the SOS distress signal on a piece of paper and stick it on the window pane.

As long as the font size is large enough, this trick will definitely work.

But Qin Chenchen thought about the problem too simply. This is the fifth floor, and the sky is almost dark, so how big of paper do you have to find if you want the people below to see the word "SOS" clearly? How bold do you have to write?

In this small office, except for piles and piles of A4 fingers, there is no bigger white paper than this.

In the end, Qin Chenchen was completely desperate.

She sat at her desk until it was completely dark.

"Alas! It's going to rain, my mother is going to get married, and God is destined to kill me! ”
