Furthermore, with the improvement of education in China, there is no longer a need to go abroad. China's education system is already quite advanced, and coupled with a safe living environment, not many people want to go abroad anymore.

After they finished speaking, the two of them sighed in unison and turned their gazes to Qi Jiu.

Qi Jiu: "..."

If she says that she has lived abroad since she can remember, will she be beaten?

That being said, there are advantages to living abroad, but they also had a wonderful childhood that she never had. China's safe society is indeed unmatched by many other countries.

It is precisely because of the country's prosperity and strength that China has occupied a significant position on the international stage.

"Actually, there's no need to be so scared. After all, when you go abroad, you'll only encounter humans, not zombies or any unknown creatures. If you do encounter them, just shoot them dead, right?"

Yu Qi and Chang Xiaoyuan: "..." That actually makes sense.

Are gun regulations not so strict in other countries?

Wait, what are they thinking?

"Um... Qi, could I borrow some of your time at lunchtime? There are some things I don't understand, could you help me with them?"

Yu You, who had never had a chance to speak before, finally found her opportunity.

Qi Jiu nodded. "Sure."

Since they've already asked, there's naturally no reason to refuse, and refusing now wouldn't be a good opportunity.

"Then you..."

"Forget about them. Ruoruo has a habit of taking a nap, and Anran and the others have important things to do at noon. What, are you afraid I can't teach you by myself?"

Before Yu You could finish speaking, Qi Jiu interrupted her directly, a faint smile playing on her lips as she stared straight at her.

After she finished speaking, Yu You could only wave her hand.

"No, what I was thinking was... it would be great if we could study together, and we could discuss the questions we didn't understand."

"Sorry, I don't have time," An Ran refused expressionlessly.

He understood Qi Jiu's intention the moment she uttered the first word.

Even if Qi Jiu hadn't said anything, he probably still wouldn't have agreed. He hadn't liked Yu You since their first meeting, and considering how he had used Qi Jiu before, he now wouldn't even want to look at her twice.

After the meal, in a private classroom, Qi Jiu looked at the notebook in her hand and pursed her lips.

"I remember this perfectly clearly, so what's wrong with it?"

The information in this notebook is quite clear. If you memorize some of the information, you can just apply it directly to make the product. People who can come here must be pretty good at studying, right?

If we call her over now, it's either because she genuinely can't do the problem, or she has other things to do.

Yu You was taken aback, and her smile became somewhat forced.

"I don't really understand this formula, and I'm not very good at it. For example, the teacher has explained this problem before, and I know how to solve it if I look at the detailed explanation, but if there is no explanation, I don't know anything about it."

In other words, you can understand the process, but you don't know where to start.

Upon hearing this, the girl nodded.

He picked up a ballpoint pen from the side and began sketching in his notebook with a flourish.

"This is the process. See if there's anything you don't understand, and tell me if there is."

Yu You took the notebook, and as soon as her eyes fell on the calculation paper next to it, the smile on her lips froze.

What is this? The process is so simple? How could anyone possibly understand it? Many steps are missing; no matter how hard you try, you can't possibly process it.

I didn't even understand the beginning of the process, let alone the later steps.

She recognizes all the numbers in her notebook now, but when they're put together...

"that……"

"Hmm?" Qi Jiu pulled out a thick book entirely in English from somewhere and was now engrossed in reading it.

Seeing this, Yu You smiled, her face flushing slightly, but she couldn't utter a word. Wouldn't it be too embarrassing if she hadn't understood a single step?

"It's nothing, I just wanted to thank you for taking the time to teach me."

After she finished speaking, the girl nodded and turned her gaze back to the book in her hands.

Watching her movements, the smile on Yu You's lips slowly faded, and in the end, she could only stare blankly at the process in her hands.

After an unknown amount of time, Qi Jiu glanced back at her watch. Meanwhile, Yu You had her calculations on a piece of paper beside her. However, her expression remained grim.

"Do you understand now?"

The little girl's lips curved into a smile, making Yu You's smile appear forced. "See, I understand now."

As soon as she finished speaking, a glint of light flashed in her eyes. "Excuse me, Qi, could you please take a look at this question again?"

Surely I can't not understand all the solution processes?

Qi Jiu nodded readily, glanced at the question, and began to sketch on the scratch paper.

Within minutes, the calculation paper showed a neat and orderly process.

Yu You quickly brought the scratch paper to her eyes, the anticipation in her eyes slowly fading. She subconsciously glanced at Qi Jiu, seeing her engrossed in her book, and didn't know what to say.

Who taught her this problem-solving approach? Will the teacher really give her marks for something so concise?

“Qi Jiu…”

"Um?"

Qi Jiu answered quickly, putting down the book in her hand. "What's wrong? Finished reading?"

Yu You pursed her lips, her face flushed, and her fingers, which were gripping the notebook, turned white unintentionally.

"So, could you help me take a look at this process?"

I originally intended to point to the first line of the process, but I continued pointing downwards.

Upon seeing this, a smile flashed in the girl's eyes, and she began to explain earnestly.

After an unknown amount of time, Yu You looked at the pile of processes that had been derived on the scratch paper, and forced a smile.

"Oh, okay..."

The calculation process was like looking at a book written in a foreign language, and Yu You was completely bewildered. What was all this about? She couldn't follow this line of thought at all.

"Then this..."

"You're still here?"

An Ran and her friends arrived at the classroom door at some point, and Leng Ruo was with them as well.

The girl glanced down at her watch. Sure enough, time flew by. In just a few questions, the lunch break was over in the blink of an eye.

"Does time really fly by?"

Yu You looked at the process on the scratch paper with some annoyance, her brows furrowed so tightly that she looked like she could trap a fly in her hair.

I didn't understand a single question, and all this time was wasted?

The girl looked at the people at the door, waved, and said with a hint of regret. "In that case, let's call it a day."
