Her words seemed to possess a mysterious magic, instantly turning the once noisy classroom, which resembled a bustling marketplace, into a completely silent environment. Zu An marveled at the extraordinary charm of a beautiful woman.

Yang Wei rolled up his sleeves, feeling full of energy and eager to make a good impression on the goddess. So he used all his knowledge to create twenty difficult questions. He was confident that not only would the students not be able to solve them, but even he himself would probably fail if he didn't think hard for a while.

He could already imagine what would happen next: that guy Zuan would bite his pen to pieces and still not be able to solve the problems, then he would act like a scoundrel and question whether the problems were unsolvable, and then he would reappear amidst the admiring gazes of the students in the classroom, slowly and deliberately explaining how to solve each problem.

Shang Liuyu, standing to the side, must have been starry-eyed too, and might even start to look at me differently from now on.

Thinking of the pleasant things, his mustache trembled with laughter.

No, no, with so many people watching, I need to be mindful of my image!

He coughed lightly and hurriedly took the test paper to Zu An: "You can still regret it now. If you can't solve even one question, you'll have to leave school."

He was only saying that on purpose to show his manners in front of Shang Liuyu, to indicate that he had no intention of arguing with a student. But the atmosphere had been built up to this point, and it was not up to the other party to back down so easily.

Zuan chuckled: "I got them all right, now it's your turn to leave school."

Not to mention Yang Wei, even the other students in the room thought that this guy must not be very smart. Only Shang Liuyu watched all this with a half-smile, as if he had guessed something.

"Ignorant brat, arrogant and conceited!" Yang Wei roared. "Today I'll teach you the price of arrogance!"

Yang Wei's anger level increased by 541!

He was clearly furious that his professional skills were questioned in front of the goddess.

Zuan shrugged and took the exam paper with a relaxed expression.

"That's it?" Zuan scoffed. To be honest, he wasn't very confident that he could answer every question, since he wasn't sure how advanced the math was in this world. But when he saw the questions on the test, he realized that he had overestimated his opponent.

"Instead of arguing here, you should hurry up and finish. If you haven't finished by the time get out of class is over, hehe..." Yang Wei didn't finish his sentence, but the meaning was self-evident.

Shang Liuyu, who was standing to the side, spoke up: "There's not much time left before get out of class ends. Isn't it too rushed? How about this, since the next class is mine anyway, I'll give you half of the class time so you can take your time competing."

Yang Wei was taken aback, but he didn't think Shang Liuyu was speaking up for Zu An. After all, the two were not related. It must be that the goddess was kind-hearted and subconsciously sympathized with the weak, and was also worried that I would be labeled as bullying the weak.

I'm so touched that my goddess is thinking of me like this.

Yang Wei was so excited that tears almost streamed down his face. He nodded hurriedly and agreed, "That's right, Teacher Shang is right. I'll give you another half-class period then."

Anyway, with arithmetic, if you can do it, you can do it; if you can't, giving you more time won't make a difference.

Zuan ignored him and started looking at the first question:

"If three people drink three buckets of water in three days, how many buckets of water will nine people drink in nine days?"

Wei Su, who was standing nearby, saw this and his eyes lit up. He quickly exclaimed, "This question is so simple, I can answer it. If three people drink three buckets of water in three days, then nine people will naturally drink nine buckets of water in nine days."

Upon hearing this, the surrounding students nodded in agreement, with only a few vaguely sensing that something was amiss, but unable to pinpoint the problem.

Yang Wei sneered inwardly. If it were that simple, would he have participated? However, he did not stop the surrounding people from talking, hoping that they would mislead Zu An.

Zuan shook his head. Even elementary school students in his previous life could solve this kind of problem. If three people drink three buckets of water in three days, then three people drink one bucket of water a day. That means each person drinks one-third of a bucket of water a day. If nine people drink one-third of a bucket of water in nine days, then multiply one-third by 81, which is exactly 27.

When Yang Wei saw him write down this answer, his eyes widened instantly. How could this be!

You should know that he saw this question in an ancient book. He got it wrong the first time. Later, he secretly used it to test many of his colleagues. Basically, most people's first reaction was that he was a naive person. How did this guy get it right all of a sudden?

However, this question is not too difficult; it's more of a word trap, and the other person might just stumble upon it by chance.

Hmph, this is the easiest question. The questions after this will get harder and harder. I don't believe you can be so lucky!

However, the other party has already answered one question correctly, so it will probably be difficult to expel him from school according to the previous agreement. Sigh, I shouldn't have made such a sure thing just now.

Upon arriving backstage, Zu An received a surge of anger points from Yang Wei, who was described as "+9+9+9...". Zu An thought to himself that Yang Wei's name truly reflected his character, as he was even stingy with his anger points.

Let's look at the second question:

A farmer's wife was washing dishes by the river. A passerby asked her why she was washing so many dishes. She replied that many guests had come to her house. Two people shared a rice bowl, three people shared a soup bowl, and four people shared a vegetable bowl. She used a total of 65 bowls. How many guests did she have?
