Back to the 1970s: Building My Fortune Through Time Trading-Chapter 468: Writing an IOU

The old man changed places with Wang Weimin opposite him and picked up the book Su Xiaoxiao had just finished reading, casually flipping to a page.

Seeing the content, the old man glanced at the confident woman opposite him, paused in his actions, and flipped two pages further.

Clearing his throat, he began, "Given a triangle with sides of 3, 4, and 5, determine if it is a right triangle."

Wang Weimin frowned slightly upon hearing this. Why is the old man posing a question now? Isn’t this supposed to be an assessment of textbook theorems? Moreover, this problem often trips up students who confuse "conditions" and "conclusions."

The old woman next to him was bewildered, being illiterate and unable to understand, but it didn’t matter. Seeing the serious expression on the teacher opposite, she figured the problem wasn’t simple, which was good enough.

As long as it makes the little girl stumble, she’ll be satisfied.

Just waiting to see Su Xiaoxiao’s embarrassment, she then heard Su Xiaoxiao speak leisurely, "3²+4²=9+16=25=5², satisfies a²+b²=c². By the reverse Pythagorean theorem, it’s a right triangle with 5 as the hypotenuse."

Su Xiaoxiao felt the problem was very simple, thinking the old man was deliberately giving her an easy one. She smiled gratefully at him.

To her surprise, the old man was somewhat shocked after hearing her answer, then picked several more, all of which Su Xiaoxiao answered smoothly.

In the end, the old man looked at Su Xiaoxiao with appreciation, applauding and praising, "Good, good, very good indeed."

Even Wang Weimin was stunned.

Unexpectedly, Mr. Su said he remembered, and he really did remember.

Not only remembered but could also flexibly apply it in real-time. This learning ability is truly exceptional.

Having taught for so many years, he had never encountered such a clever student.

Given time, this little girl’s future is indeed limitless.

The old woman couldn’t understand their question and answer but gradually realized something might not be right through the amazed stares of the people around her.

"Oh, my stomach hurts so much, it’s killing me, I need to rush to the toilet."

Saying this, she grabbed her bundle from under the seat, ready to make a run for it.

The next moment, her arm was caught by a small hand: "Grandma, a bet’s a bet, you wouldn’t be thinking of reneging, would you?"

Why is this darn girl so quick to react?

"Look at what you’re saying, girl, I’m not that kind of person. I just have a stomachache and need to go to the toilet. You wait a moment, okay? I’ll definitely give you the money when I get back."

She said, preparing to escape, but Su Xiaoxiao continued to hold onto her arm without any intention of letting go.

"What is this little comrade doing? I’m about to soil my pants, and you still won’t let go! I already told you I’d give it to you when I returned, and my seat is still here. I will definitely come back."

Su Xiaoxiao squinted and smiled at her, "Grandma, why don’t you give me the money first, and you can go after?"

"I’m about to burst, it won’t take long, I’ll surely give it later..."

She said, breaking free from Su Xiaoxiao’s hand, walking quickly towards the exit, only to find her bundle seemed to be held by someone.

Turning around, she saw it was the darn girl again. Is she never done?

The old woman was almost spitting blood with anger, "I already said I’d give it to you, why are you being so relentless? So many people are watching, I’m definitely not running off, relax."

"Grandma, that’s not what I mean. Look, the toilet is so small, it’s inconvenient for you to take so many things. I’ll watch them for you, don’t worry, I’ll definitely keep a good eye on them."

The old woman: "..."

This darn girl, she just wants to take advantage of the situation and run off with the bundle. She’ll be arriving at her station soon, and by hiding in the toilet for a while, she can get off the train directly, and the girl won’t be able to find her.

Wang Weimin next to her also came to his senses, chiming in, "Auntie, Mr. Su is right. You can leave your things here; with so many of us, they definitely won’t be lost."

Old woman: Damn it, this isn’t about losing things!

She wants to run, damn it!

With so many people present, running off seems impossible.

She could only pretend to go to the toilet, then came back trying to play the sympathy card with Su Xiaoxiao.

"Girl, you see, Grandma was just joking with you. No need to take it so seriously, right? Grandma admits you’re talented in studying, much better than my grandson. You see, Grandma’s family is very poor, really can’t take out the money..."

She thought the girl wouldn’t dare continue asking her for the ten bucks, seeing her age and hearing her words. 𝑓𝑟𝑒𝘦𝓌𝑒𝑏𝑛𝑜𝘷𝑒𝘭.𝒸𝘰𝑚

Just as she thought this, she heard Su Xiaoxiao say, "Grandma, are you trying to default on the debt?"

The old woman: "..."

Before she could speak, people around started to gossip.

"The betting was initiated by the old lady earlier. What now? Lost and wants to default? At such an age, it’s shameless."

"Tsk tsk tsk, planning to leverage her age to go back on her word, really not nice."

"Of course, if the girl lost earlier, would she say the same? Isn’t this about thinking the young girl is easy to bully?"

A group of people expressed their indignation, pointing fingers at the old lady.

The old woman felt humiliated, endured it, and pitifully looked at Su Xiaoxiao, "Girl, Grandma really doesn’t have the money, how about this, I have only two bucks, I’ll give them both to you..."

Before she finished speaking, someone nearby said.

"Oh, isn’t that Secretary Zhang’s mother from our village? Always looking down on others? What now? Secretary Zhang has fallen? And pretending to be poor?"

"Hey, don’t say it, but it’s true. Young comrade, don’t be fooled by the old woman; her son is a secretary to a big leader, the family’s condition is very good, how could she not afford ten bucks?"

Su Xiaoxiao was a bit hesitant before, worried that the old lady’s family was really troubled, after all, she didn’t expect these ten bucks to make her rich, just wanted to teach the old lady a lesson.

Who knew this old lady was so shameless.

"Grandma, you proposed the bet. Your son is also a leader, how come you’re so unreasonable? If this gets out, it’s not a good look for your son."

The old woman hated hearing anyone say anything about her son. To her, her son was extremely promising, first among their ten-mile circle.

"What nonsense are you talking about, girl? I didn’t say I’d renege, just don’t have enough money now, giving you part first, what’s wrong with that?"

The old woman said with self-righteousness, reaching into her pocket to take out two bucks and slap them into Su Xiaoxiao’s hand: "Here’s two bucks first, I’ll write you an IOU for the rest."

"Fine, then write the contact address and name clearly on the IOU, just can’t be random, there are fellow villagers on this train, I’ll need to verify..."

The old woman gritted her teeth, "Write it, just write it, I don’t know how to write, you can write it, I’ll stamp it."

This darn girl is so stubborn, but it’s okay to write it. She overheard that the girl was a salesperson at the Binhe City department store; surely she won’t travel so far to ask for money at her house?
