He took Chi Xiao's books and test papers out of his shopping bag, transferred them to his backpack one by one, and unexpectedly pulled out a light yellow envelope.

He bent down and picked it up.

"Yo, love letters?"

Although he felt that the student's privacy should be respected, Si Yan didn't control his hand much at that moment, and when he was thinking about whether to open it, his fingers had already picked up the paper clip on the cover of the envelope.

Unlike what he imagined, this wasn't a love letter, it was an old, handmade birthday card.

It was Chi Xiao's own handwriting, and it was given to him, the date was September 10 last year, which was Teacher's Day and his birthday.

The handmade greeting card is very beautifully made, and the handwriting on it is also very neat, but I don't know why it didn't reach him in the end.

When Si Yan folded it back and played it back, he saw the reason on the back, and the handwriting was obviously much messy:

I'm really ridiculous, what age is it, high school students still send handmade greeting cards to teachers?

If someone knows about it, you'll laugh off your big teeth, right?

But what can I do, there is not a penny in my empty pocket, I have never had the luxury of how rich my parents can be, as long as ...... It's enough to make me look up and be a human being, but why can't I even ask for it?

Why is God so unfair to me.

……

"Hey."

Si Yan's second sigh of the night.

This child is really overwhelmed by poverty, and the important thing about gifts is never the price, but the heart.

Instead of putting the envelope in his backpack, he placed it on the bookshelf he used to place the gifts from his students.

The next day.

Chi Xiao got up very early as usual, and when he woke up, he found that Si Yan was sleeping on the sofa in the living room, and his heart did not affect the master's consciousness as a guest, and after a simple wash, he quietly left the teacher's apartment.

He had fifty dollars in his pocket and a flip phone that was an antique in the era of smartphones.

He used this mobile phone to send a text message to Han Bo: On the rooftop of the north building of the teaching building, come alone.

He originally wanted to trick people into going outside the school, near the last comic show, but he felt that there were too many unstable factors outside the school, and it was easier to stay in school, just because the third year of high school was on vacation, and the other grades had not yet returned to school, and there were no students in the empty teaching building, which was a godsend.

System Jun felt the murderous aura in his body, and chanted the scriptures in his mind: civilized society, civilized society, civilized society......

Clinker's classmates who usually hated its broken thoughts the most were very calm today, completely ignoring his existence.

Chixiao was fully prepared and waited quietly on the roof of the teaching building.

God help me, today's day is extraordinarily hot, the sun is very dazzling at nine o'clock, and the time passes minute by minute, and the flowing air is gradually heating up.

Half past ten.

It was already very hot and dry, and with a creak, the iron door of the roof opened.

Chi Xiao squinted, counting down to one, two, three, and the moment Han Bo's unbeaten head was revealed, he had already pounced on it, wrapping two washed and yellowed laces—which he had just pulled out of his shoes—around Han Bo's neck.

He didn't hesitate for half a second, and directly poured all the strength of his body into the two shoelaces, which instantly made Han Bo's face flush.

[Ahhh Civilized society, dear! 】

Oh, civilization.

He has been treated 'civilly' in his life.

[Let go! Ancestor, he's really going to die! 】

Going to die?

When he was about to die, what were the people around him doing, they were laughing, they were proud, they were admiring their proud 'work'.
