Lin Fan glanced at the system list, closed his eyes, and fell into a deep sleep.
The next day, a wisp of warm morning sun passed through the window and gently sprinkled into Dorm 104.
"Jingle bell!"
Almost at the same time, three different rings sounded in the bedroom.
Then, Ma Zhong, Song Yi, and Zheng Jinbao, who had been sleeping soundly, sat up from their beds together and quickly got dressed.
Lin Fan couldn't help wondering, "What's wrong with you guys?"
Yesterday, they had dawdled for a long time before reluctantly getting up.
Today, they were simply like different people.
"Teacher Tian Tian's class, it's Teacher Tian Tian's class!" shouted Zheng Jinbao.
Lin Fan was still puzzled, but he still followed along to get dressed and wash up.
Walking on the way to the classroom, Lin Fan looked at the anxious steps of the three and asked, "Is this Teacher Tian Tian's class very important?"
"Important! Too important! If I don't see Teacher Tian Tian for a day, my whole body feels uncomfortable!" said Zheng Jinbao.
Song Yi said, "Brother Fan, walk faster! Otherwise, there won't be any seats later."
No seats? University classrooms were very spacious.
Lin Fan had gone to class these past two days, and there had always been many empty seats in the classroom.
Today, there wouldn't be seats? Lin Fan carried full confusion and finally arrived at the classroom.
It was only at this moment that he understood why Song Yi and the others had said that.
It was still more than ten minutes before class.
However, the classroom was already pitch-black and packed with people.
Zheng Jinbao pointed to the seats in the back row and said excitedly, "There are still four seats there. Let's go, let's hurry over before someone else takes them."
When Lin Fan and the others sat down, all the seats were already completely filled.
As for those who entered the classroom again, upon seeing the seating situation, they could only sigh helplessly and leave.
Lin Fan asked, "Why are there so many people for this teacher's class?"
"You'll know in a moment," Song Yi said excitedly.
"Jingle bell!"
At this time, the class bell rang.
In an instant, the originally noisy classroom instantly quieted down as if a needle had dropped.
"Tap, tap, tap!"
A burst of crisp footsteps approached from far to near.
Soon, a top-tier beauty walked up to the podium.
She had a cascade of waterfall-like hair, and on her delicate face that could be broken by a blow, she had willow-leaf eyebrows, phoenix eyes, a petite and exquisite nose meticulously carved by God, and a lively cherry mouth.
A white dress outlined her perfect figure.
Coupled with a special charm exuding from her person... as long as one glanced at her, they simply couldn't look away.
Lin Fan couldn't help observing with the Eye of Truth.
Appearance: 98. Favorability: 60. An appearance of 98! Nearly a full score!
Guiding fish to sink and geese to alight, putting the moon to shame and flowers to blush. Perhaps that was referring to her.
No wonder the classmates in class were in such a hurry to come to her class.
Favorability, 60? It reached the passing line of 60 points! Her favorability toward him seemed pretty good? Could this be a teacher who treated every student as a friend?
At this time, Hu Tian, standing on the podium, said, "Today, we will continue to explain "Higher Algebra"..."
Her voice, like her name, was very sweet and rich in magnetism, making people simply not want to miss even a single sentence.
A moment later, Hu Tian wrote a problem on the blackboard: Find all prime numbers p, q, r such that p^q + p^r is a perfect square number.
"Everyone can try to solve it," Hu Tian said.
All the students immediately picked up their pens and continuously wrote on their scratch paper.
They wanted to use the shortest time to solve the difficult problem and thereby gain Hu Tian's attention.
However, soon, the students all scratched their heads in exasperation.
This was because they simply didn't know how to answer it.
Zheng Jinbao anxiously said, "Ma Zhong, haven't you solved it yet? So much time has already passed!"
Ma Zhong said, "Don't rush!"
"Don't let anyone else beat us to it! If Ma Zhong can't solve it, then I hope no one can solve it!" Song Yi prayed silently.
Hu Tian's pair of bright, water-like eyes scanned the classroom a circle, seeming to search for someone who could solve the problem.
Unfortunately, absolutely no one raised their hand to answer.
Thus, Hu Tian said, "Lin Fan, can you come up and solve it?"
Lin Fan slowly stood up.
Immediately, the gazes of all the students fell uniformly on Lin Fan.
That was envy, that was jealousy!
Lin Fan didn't understand why this Hu Tian would suddenly call his name.
He didn't seem to have raised his hand either? Lin Fan first looked at the problem on the blackboard, thought about it slightly, and then walked to the podium, picking up a piece of chalk to write quickly.
If q = r, then p^q + p^r = 2p^q, so p = 2, and q is a prime number.
Therefore, (2, q, q) is a triplet of prime numbers satisfying the condition...
In summary:
(2, 2, 5), (2, 5, 2); (3, 2, 3), (3, 3, 2); (2, q, q), (q = 3)
Soon, the blackboard was filled with a large number of formulas, and the answer was finally derived.
Hu Tian nodded and said, "The solution is very correct, and furthermore, it is even simpler than the calculation method I had in mind."
Lin Fan said, "However, this is still not the simplest problem-solving method."
"Oh?" Hu Tian immediately became interested.
Then, under Hu Tian's expectant gaze, Lin Fan wrote down the problem-solving steps that were nearly half simplified.
When Hu Tian saw this, her beautiful eyes lit up slightly, and she praised, "I never expected that prime numbers could still be calculated this way..."
After a brief ponder, Hu Tian spoke again, "If this method is used, perhaps..."
Hu Tian couldn't help but quickly write on the blackboard.
Q = p1m1 + b1 = p2m2 + b2... pkmk + bk. Q = 41 = 2m + 1 = 3m + 2 = 5m + 1...
Not long after, Hu Tian stopped the chalk in her hand.
Then, she looked at Lin Fan with a look seeking help.
Lin Fan said, "The Twin Prime Conjecture?"
Ever since obtaining the Professor-level Mathematics Experience, he had browsed through quite a few mathematics-related materials, and of course he knew the world-class difficult problem—the Twin Prime Conjecture.
Hu Tian nodded and said, "Yes."
Lin Fan picked up the chalk and quickly wrote below Hu Tian's work.
However, even though Lin Fan possessed the Professor-level Mathematics Experience coupled with Absolute Focus, if he failed to trigger the 5% Flash of Inspiration, he would still be completely unable to solve the Twin Prime Conjecture.
After a long while, Lin Fan also stopped.
Hu Tian said, "The calculation above, if changed to p^q + xb = 3m + 2... What do you think?"
Lin Fan thought for a moment, shook his head, and said, "No, it should be changed to 5p + 5m + p^q..."
The two discussed while writing down the problem-solving steps.
Soon, the entire blackboard was filled with dense formulas.
