At the same time, he was flipping through books and found relevant problem-solving cases.
The female teacher looked at Lin Beichen flipping through books as he walked and couldn’t help but chuckle a few times.
"There are no answers in the books!"
"There are only cases, but even if there are cases, you can’t understand them without explanations!"
"If you can’t solve it, I will report to the principal, and you won’t be allowed to miss any class in the future!"
"Also, you must complete... complete..."
Before the female teacher finished speaking, Lin Beichen had already walked up to the blackboard with the book in hand, without pausing or looking at her.
Instead, he grabbed a piece of chalk, and with a few swift moves, wrote down the answer!
Just like that, effortlessly!
Without even making a draft, he directly wrote down the answer next to the equal sign!
In the distance from his seat to the blackboard, Lin Beichen had already completed the calculation in his mind!
Before the female teacher finished speaking, she was stunned into silence!
She looked in disbelief at the string of numbers near the equal sign, thinking it was impossible!
"Teacher, did I get it right?"
Lin Beichen still asked the female teacher respectfully whether the answer was correct.
In fact, he didn’t know this mathematical formula at all before the female teacher called on him.
But during his walk to the blackboard, with his extraordinary talent, he inferred the solution to the problem on the board by comparing it with the cases in the book and completed the calculation in his mind.
The class instantly went silent, everyone held their breath and stared at the blackboard, waiting for the teacher’s response!
This also made Han Yuan, Liang Dong, and Wu You, who sat next to Lin Beichen, break out into a cold sweat for him.
"The answer is correct!"
The female teacher was shocked for a moment before finally giving a reply. She tried to control the shock on her face, but her heart was already in turmoil!
She never thought that someone who had hardly attended her class could so easily solve a mathematical formula that she had just improvised!
She was convinced that this answer couldn’t be found in any book!
Nor could it be found online!
It was a spur-of-the-moment question, and even seniors would struggle to solve it in such a short time.
Moreover, he did it without making any drafts!
"I’ll give you another problem. If you can solve this one, you can come and go from my class as you please!"
The female teacher still didn’t quite believe it, thinking maybe Lin Beichen just happened to have studied this problem before; otherwise, such talent would be astonishing!
"Sure, teacher, go ahead!"
Lin Beichen agreed without thinking, respectfully made a gesture of invitation, and then stepped aside to wait.
The female teacher then wiped the blackboard clean and started writing with chalk once more. This time it took a bit longer as she calculated in her head for a while.
She changed the problem midway, editing it several times!
In the end, she incorporated all the knowledge she had learned from this course over the past few years into this one problem!
She thought that if he could solve it, she would give him full marks for this course!
The entire blackboard was filled with dense numbers and symbols, covering every corner!
The top students and class representatives in the classroom, upon seeing the full blackboard of numbers and symbols, immediately gave up!
They didn’t even bother flipping through their books, as there were no such complex mathematical formulas in the freshman textbooks.
Everyone unanimously believed that the teacher was making a statement!
Aiming to break Lin Beichen’s arrogance! And to demonstrate to everyone that there is no end to mathematics!
That what everyone learned is merely superficial, not even at the threshold!
This problem left everyone in the classroom feeling utterly bewildered!
"Go ahead!"
The female teacher handed the chalk to Lin Beichen and then stepped aside.
However, this problem indeed stumped Lin Beichen. To him, it was like asking a kindergartener to solve a problem that even a high school teacher couldn’t solve!
"Teacher, I can’t solve this problem!"
Lin Beichen honestly conveyed his current predicament.
This statement lifted a lot of weight off the shoulders of everyone in the classroom, as the question itself was headache-inducing. If someone could solve it, that would be unbelievable!
And this person hadn’t even been to class a few times, so what did that make those who attended every day?
Upon hearing this answer, the female teacher finally showed a calm smile, adjusted her glasses, and said:
"It’s normal not to be able to solve it, sit down and pay attention in class!"
"Being able to solve the first problem shows you have some talent, but in the face of boundless mathematics, it’s far from enough!"
Lin Beichen shook his head and said, "Teacher, there’s a mistake in this problem!"
"Based on the final formula, it has hundreds or even thousands of solutions!"
"...."
Upon hearing this, the female teacher gasped, staring intently at the string of characters Lin Beichen pointed out!
Sure enough, as Lin Beichen said, she had used multiple formulas to increase the difficulty, overlapping them, and included the most challenging formulas from the entire semester!
She hadn’t carefully examined the compatibility of these formulas when combined.
The female teacher then recalculated using her notes and filled two pages of scratch paper, finally confirming that Lin Beichen was right!
She was shocked!
She scrutinized Lin Beichen with disbelief, even suspecting that a new math prodigy was about to be born!
After a while, the female teacher finally withdrew her gaze, corrected the erroneous characters in the formula, making the entire calculation process coherent and error-free!

"Alright, you can give it another try!"
The female teacher stepped aside again, handing the chalk to Lin Beichen.
This time, though, Lin Beichen didn’t write the answer directly as before.
"Teacher, may I borrow your notes on the calculation?"
The female teacher felt puzzled. The notes only proved there was an error and had nothing to do with the final answer!
Thinking it wouldn’t help with solving the problem, she handed them to him.
Lin Beichen took the notes, instantly running calculations in his mind, and quickly grasped the teacher’s problem-solving approach!
But it still took him a long time, over half an hour, before he finally wrote the answer on the blackboard.
The female teacher took a look and exhaled deeply, "Beichen, from now on, you can come and go as you please in my class!"
After saying that, she left the classroom. They had already been dismissed for a while, and everyone stayed to see if the final answer was correct.
Upon receiving the teacher’s reply, the entire classroom erupted in excitement!
At that moment, Lin Beichen became a legendary figure in their eyes!

Within the Divine Light Country, at Shenzhao University.
Hao Jianhua, along with the remaining students who participated in the academic exchange at Shenzhao University, did not rush back to Great Xia.
After learning that Lin Beichen was safe and had been sent back to Imperial Capital University by the Security Bureau, and that all the procedures for their group had been completed with the Security Bureau’s involvement,
There was no longer anything to worry about.
So Hao Jianhua continued the academic exchange at Shenzhao University with the remaining students, ensuring that they prepared summaries and reports of their exchange experiences.
Followed by various networking gatherings, photography sessions, and handshakes and photo-ops with Shenzhao University President Nohara Hikofu.
The goal was to maximize the impact of this academic exchange, showcasing it to the media and other rival universities.
It also added credibility to Imperial Capital University.
Even though the volcanic activity within the Divine Light Country continued, the academic atmosphere at the university remained vibrant and unaffected.
After a week of completing all the projects and procedures of this academic exchange, Hao Jianhua finally led the students away from Shenzhao University and headed back home.
