Brother! This is the adoption certificate. I don't want your sister-in-law!

The midterm exams were fast approaching.

The day before the exam, the atmosphere in the classroom was as tense as a taut string.

Fang Yu flipped through his textbook noisily, muttering to himself, forgetting the next sentence after memorizing the previous one.

A few girls in the front row huddled together, quizzing each other on chemical equations. The person who got it wrong had to buy a bottle of soda.

Even Li Ze, for the first time ever, disregarded discipline because he himself was frantically flipping through his notebook of wrong answers.

It seems that in order to maintain his image as class monitor and a model student, Xiao Li is quite diligent.

Su Xiao wasn't particularly nervous.

During this period of time, he received mixed doubles tutoring from Xu Niannian and Su Wanning. Although he dared not say that he made leaps and bounds, he at least evolved from "not understanding anything at all" to "being able to understand most of it".

Chemistry was the subject in which he made the most progress.

After all, Xu Niannian, who was first in the class, provided tutoring throughout the process.

One major problem that makes it difficult for struggling students to improve is that they don't understand the material and don't know who to ask.

Xu Niannian's existence solved Su Xiao's problem, and could solve almost 95% of the problems he couldn't solve.

As for the remaining 5%, forget about it, since Xu Niannian doesn't know it, and I don't need to know it either.

He was hunched over the table flipping through Xu Niannian's chemistry notebook when he suddenly felt someone gently touch his arm.

Xu Niannian turned to the side, holding a slip of paper in both hands, and handed it to him.

The strip of paper was torn from the exercise book and folded neatly.

"What, is this a cheat sheet? You even copied the chemical equations?" Su Xiao asked curiously.

No, no.

Xu Niannian quickly shook her head, her voice trembling with nervousness.

Su Xiao took it and unfolded it.

A line of neat, small handwriting was written on it, each stroke carefully outlined: "Do your best on the exam! Strive to pass chemistry!"

At the end, I drew a small smiley face, but it was drawn crookedly, probably because it was the first time I had ever drawn something like this.

Su Xiao felt a warmth in her heart, but a mischievous smile appeared on her face as she tucked the note between her fingers and waved it.

"Why do I only need to pass chemistry? What about math? English? Physics? Do you look down on the other subjects?"

Xu Niannian lowered her head, her fingers gently rubbing the edge of the textbook.

"If you fail chemistry, the teacher will transfer you to another school."

Su Xiao seemed to remember.

He Shaojun did say that if Xu Niannian failed the midterm chemistry exam, he would have to move away from her.

He had said those words a month ago, and he had almost forgotten them himself, but Xu Niannian remembered them clearly.

He tilted his head to look at her, and the corners of his mouth slowly curved up.

"What, you don't want me to be transferred?"

Even though she knew it was teasing, Xu Niannian still blushed and nodded earnestly.

She nodded very slightly, but each nod was forceful.

Why?

Xu Niannian didn't even think about it, her voice soft.

"Because you were transferred, I won't have any students anymore."

student.

Su Xiao was stunned for a moment.

When he asked her questions, he would always call her "Teacher Xu" with a playful smile.

"Teacher Xu, how do I do this problem?" "Teacher Xu, I forgot to bring my homework, can I borrow it?" "Teacher Xu, don't go, I have another problem."

He shouted it so casually, never thinking that those two words carried any weight.

But Xu Niannian kept it in mind.

She had never been a teacher, never been needed by anyone, and never been called "Teacher Xu" by anyone who looked at her with that earnest gaze, waiting for an answer.

She probably regarded those two words as some very precious title, keeping them hidden in her heart and carefully cherishing them.

Su Xiao reached out and pinched her cheek; it was still so soft and smooth.

"Then I'd better study hard for the exam."

He loosened his grip, twirled the pen between his fingers, and chuckled, "If you do well on the exam, we can continue our passionate teacher-student romance."

Xu Niannian's face turned red again.

She didn't dodge, but simply lowered her head, and the corners of her mouth curved up without her even realizing it.

The midterm exams lasted two days.

I took the exams in the morning and then again in the afternoon. By the time I finished the last exam, I felt like my whole body was about to fall apart.

When Fang Yu came out of the exam room, his eyes were glazed over. He said that he had written the formula for the last big math question wrong, losing twelve points for nothing.

Li Ze was flipping through the wrong questions in his notebook, checking the answers. The more he checked, the paler his face became.

Su Xiao tossed her pen into her bag, leaned against the corridor railing, looked at the gloomy sky, and let out a long sigh.

Unlike before, this time after the exam, his heart was at ease, not dead.

He could understand about 70% of the questions. He did the ones he knew how to do, and for the ones he didn't know how to do, he wrote down some steps. At least he didn't hand in a blank paper.

As for the results, we'll see when the results are released.

He has more important things to do now.

The day after the exam, Su Xiao brought out the six boxes of USB drives she had stockpiled at home early in the morning.

These past few days, he's been keeping a close eye on tech newspapers and online forums to check market prices. The price of a 128MB USB flash drive has tripled, rising from thirty-three to just over one hundred.

The market is experiencing a shortage of supply, with wholesalers scrambling to buy goods, and many stalls have already sold out.

But he knew in his heart that this surge was short-term, and once upstream production capacity caught up, prices would plummet back down like a roller coaster.

Knowing when to stop is the best policy.

He hired a few elderly men who were sunbathing at the entrance of the residential area to help him move the boxes. He paid each of them ten yuan. The men happily carried the six large cardboard boxes into the taxi.

When we arrived at the second floor of the Guochu Computer City, the area with the USB flash drive stalls was even more bustling than last time.

The counter was crowded with people, some buying in bulk, some grabbing goods, and others holding cash and asking around, "Do you have any in stock?"

The numbers on the price tag were erased and rewritten, then erased again: 110, 115, 118. Each time the price was refreshed, it went up a little.

Su Xiao pushed the cart around, asking each shop about the purchase price.

Some stores offered 110, some offered 112, and the highest price offered was 115.

He didn't rush to make a move. After wandering around for a while, he finally found an inconspicuous stall in a corner.

The shop owner was a straightforward man in his early thirties. After looking at his goods, he immediately quoted a price of 120.

"Six hundred, all taken. Cash on delivery, bank transfer."

Su Xiao didn't waste any words and wrote down her bank card number on a piece of paper and handed it over.

Seventy-two thousand yuan.

My phone vibrated; a text message alerted me of a balance change.

He leaned against a stone pillar at the entrance of the computer mall, looking down at the bank's text message, his mouth practically stretched to his ears in a wide grin.

We're finally rich!

Several colleagues who had just watched him sell were still gossiping, saying that he had acted too hastily, that the price of USB flash drives would definitely rise again tomorrow, and that he would lose several thousand yuan on this trip.

Su Xiao put the bank card in her pocket, too lazy to explain.

Prices may indeed rise tomorrow, but what about the day after tomorrow, and the day after that? Who knows?

I'm now giving this advice, "Know when to stop," free to those colleagues who are criticizing him.

Stepping out of the Guochu Computer City, a chilly autumn wind swept over me.

Su Xiao zipped her school uniform all the way up, stood on the steps at the main entrance, watching the cars coming and going on the street, and pondered her next move.

Seventy thousand yuan in start-up capital is neither a lot nor a little.

What should we do? We can't expect to trick the school's young lads into buying secondhand phones.

After all, there are only so many young men with a certain level of energy, and the spending power of other students cannot keep up.

Moreover, Su Xiao was also worried that if one day the young man discovered that the phones he sold them were refurbished second-hand phones, he might kill himself.

Just then, a young couple walked by.

The girl, linking arms with the boy and resting her head on his shoulder, said sweetly, "Honey, I heard Orange Isle nearby is really beautiful. Let's go there for a stroll."

The boy patted her hair. "Let's go."

Su Xiao's ears twitched.

Want to wander around?

He stood on the steps, his mind suddenly spun like a lightbulb had been switched on.

Old mobile phones, old MP3 players, old computers, and old digital products.

These items are everywhere in the student market. Where there are sellers, there are buyers; where there are buyers, there are refurbished items; and where there is refurbishment, there is a price difference.

Damn it, I'm going to get into secondhand recycling!
