Is Chapter 16 B or C?

The title "River God" actually represents a kind of mockery and ridicule.

But when Xu Qiao shouted like that, it actually gave off a strange sense of power and sanctity.

It's like when a fat guy in a later generation shouted "YYDS" during a live stream, and from then on, that slogan became synonymous with "NB".

At this moment, the word "god" seemed to be given a new definition.

Class Three used to have two gods, but now only Jiang Xun deserves that title.

In just two months over the summer vacation, his score soared from over 300 to 598!
He went from being one of the worst students in the class to second in the class, second only to Yang Kaiyi, who was in first place.

He topped the grade in mathematics, surpassing the second-place Yu Sheng by 13 points!
This was unprecedented in the entire history of Yinxian No. 1 Middle School, to the point that even the principal was alarmed.

He personally spoke with Lao Zhu, urging him to make sure Lao Zhu nurtured this promising talent.

Even if some people still had doubts, they dared not discuss them openly at this point.

When Jiang Xun scored 485 points, they still had the right to discuss it; now that he has scored 598 points, they feel terrified even to discuss it.

At best, this kind of thing is detrimental to class unity; at worst, it affects the development of the school!
This is God, who cannot be named or looked upon directly.

During the first math class, Jiang Xun still didn't listen to the lesson, but instead picked up a book called "Wealth Mindset" and started reading it.

He borrowed this from the bookstore. There are several bookstores near the school gate where you can borrow books, but most of them sell novels.

He had to visit several bookstores before he was able to borrow a few useful books.

Besides "Wealth Mindset," he also has "Deep Cognition" and "Beyond IQ," among others.

Although these books cannot provide Jiang Xun with any skills, they can increase his mental attributes.

However, according to the progress of the book's collection, even if he finishes reading "Wealth Mindset", he will not be able to gain 1 point of mental energy.

He has noticed that the difficulty of improving the three-dimensional attributes increases as you progress, and many skills cannot increase attribute values ​​after they are acquired.

For books that purely increase attributes, you need to read several to gain just one attribute point.

Therefore, it is obviously unrealistic to expect to quickly grow into a fully leveled human.

At that moment, math teacher Shi Tingbo was just going over the 12th multiple-choice question on the monthly exam, which was the most challenging multiple-choice question.

Given that a, b, and c are all positive real numbers, and a + b + c = 3 and ab + bc + ca = 2, find the minimum value of a + b.

The problem seemed simple, but when Shi Tingbo asked everyone about their thought process, the whole class fell silent; not a single person spoke.

Even Zhang Tao, who scored 108 points on the test, kept his head down and didn't dare to look Shi Tingbo in the eye.

At this moment, everyone's eyes subconsciously turned to Jiang Xun in the corner.

If we were to say who in the class is most likely to answer this question correctly, it would undoubtedly be the top student in the grade who scored 137 points.

This test paper was very difficult, with a passing rate of less than 10% for the entire grade, and fewer than 30 students scoring above 100.

Jiang Xun's ability to surpass Yu Sheng, who had long held the top spot in the grade, and achieve a high score of 137 under these circumstances speaks volumes about its significance.

"Jiang Xun, why don't you say something?" Shi Tingbo said, seeing that everyone was looking at Jiang Xun.

Jiang Xun glanced at Brother Bo, then reluctantly put down the book "Wealth Mindset" in his hand and casually picked up Xu Qiao's test paper from the side.

Clearly, he didn't even bring the test paper, because he had no intention of listening at all.

He was still wearing his blue and white school uniform, with his jacket zipper open, revealing his slightly protruding pectoral muscles.

With a height of 179 cm and a relatively robust physique, he already possesses a certain imposing presence, like a lion gradually growing into adulthood.

Under the watchful eyes of all his classmates, his clear voice, tinged with a hint of laziness, rang out in the quiet classroom:
"Since a+b+c=3, we can directly express c as c=3(a+b), and substitute this expression into ab+bc+ac=2."

"We get ab + (a + b)(3(a + b)) = 2, which simplifies to: ab = (a + b)23(a + b) + 2."

"Then we use the basic inequality to get (a+b)2≥4ab, and substitute ab=(a+b)23(a+b)+2 into the above equation."

“得到(a+b)23(a+b)+2≤(a+b)2/4,3(a+b)212(a+b)+8≤0。”    “最终解得a+b的最小值为6-2倍根号3。”

Jiang Xun spoke slowly and steadily, making sure everyone could hear him clearly.

Some students with a better foundation fully understood his problem-solving approach, and their faces showed an "I see" expression.

Those who didn't understand were also impressed but didn't get it.

Without the teacher leading the way, everyone spontaneously clapped, and most of them wore expressions of admiration and envy.

If Jiang Xun is only slightly better than others, some people might disagree.

But his math score, which is in a league of its own in the entire grade, can only make people sincerely say – NB!

Shi Tingbo nodded with a big smile, looking at Jiang Xun as if he were looking at his own son.

“Very good, Jiang Xun, please have a seat.”

After Jiang Xun sat down, he slapped the test paper onto Xu Qiao's face, who was showering him with compliments, and continued to study his book, "Wealth Mindset."

"He looks so irritating." Yang Kaiyi, who had been watching Jiang Xun the whole time, couldn't help but wrinkle his nose when he saw Jiang Xun's nonchalant demeanor.

"What did you say?" Xie Xiaoqian asked instinctively from the side.

Seeing Yang Kaiyi shake his head and remain silent, she continued speaking to herself:
"Why do I feel like this guy is getting more and more handsome? Do people with good grades just have some kind of aura about them?"

"Boring." Yang Kaiyi shook his head and wrote down the ideas Jiang Xun had just explained on the test paper.

A few minutes later, the bell rang, and Jiang Xun felt his eyes getting sore. He decided to go to the corridor to relax by looking at the pretty girls on the playground.

Just then, a delicate fragrance, like a rare orchid in a secluded valley, accompanied by a faint scent of a young girl, appeared before him.

"This, question 16, could you explain it to me?" Yang Kaiyi stood there prettily, looking at him somewhat shyly.

Today, Yang Kaiyi wore a pure white lace-trimmed short-sleeved top and skirt, and her long black hair was tied up with a white ribbon.

A black ribbon tied into a bow was tied in front of her chest, and a few catfish whiskers were casually scattered on her pretty face.
Her large, dark, bright eyes were watery, with a pure yet tender quality that could make anyone lose their will to resist.

She was originally wearing a school uniform jacket, but she took it off at some point.

Looking at the stunningly beautiful girl before him, Jiang Xun recalled a similar scene from a long, long time ago.

It was rare for the beautiful class monitor to ask him a question again, so he couldn't resist teasing her and deliberately put on a sullen face, saying:

"I won't explain. You beat me up last time I asked you to help me with a problem."

Xu Qiao, who was standing next to him, couldn't help but give him a thumbs up. It was really impressive that he could refuse the class monitor's question so directly.

Yang Kaiyi blushed. She hadn't expected that after finally mustering up the courage to come over, she would be rejected.

However, she knew Jiang Xun was joking with her, so she wasn't angry. She whispered:
"I'm sorry. I apologize to you."

"An apology is enough," Jiang Xun insisted.

"Then what else do you want?" Yang Kaiyi glared at him, thinking, "Do you really think I have no temper?"

"Unless you answer one question for me."

"Say!"

Is it B or C?

"Jiang Xun!!"
