Chapter 202: Question-solving Battle

The wind blew up the curtains, making Lian Chengyue unable to see the boy's facial features. He could only see Yang Feng sitting next to him and talking incessantly.

"What's wrong?" Shi Ruzhuo asked him.

Lian Chengyue responded with a puzzling sentence: "The classroom is still empty, why are they sitting in the back?"

Shi Ruzhuo: "Maybe..."

Lian Chengyue: "It seems that they don't like studying very much. Or maybe they came here for other purposes."

Shi Ruzhuo shut up and wanted to persuade Lian Chengyue not to fight with the air.

Five minutes before class started, the students gradually filled the classroom. Lian Chengyue no longer paid attention to the person behind him. He sat in the middle of the first row, took out his notes and began to review his lessons.

Lian Chengyue said: "The content of the class is fleeting. Taking notes can deepen your memory. It's interesting, but this is just an extremely simple technique."

Shi Ruzhuo: ...

Lian Chengyue added: "Using different colored water pens to take notes can help people quickly distinguish between key points, doubts, and ordinary notes. This allows me to deepen my memory of learning content during my spare time. This method is quite unique and I have mastered it."

Shi Ruzhuo: "Please shut up, you are disturbing me while I am reading."

If Lian Chengyue only provided internet access to the village, then Shi Ruzhuo can be said to have provided internet access in the Stone Age. Compared to Lian Chengyue, he lacks one very important advantage: Lian Chengyue is younger than him and more adept at accepting new things.

But Shi Ruzhuo is indeed a well-known genius of Yinbing Pavilion. Every effort brings a reward. In order to continue being a villain in the new world, he is trying hard to memorize Arabic numerals and operation symbols.

Lian Chengyue said: "Senior, are you still memorizing these numbers and symbols? I have memorized these symbols in the last class. You learn a little slower than me, but this is normal."

...You kid, you want to be killed, right?

Shi Ruzhuo was about to scold him when he saw Lian Chengyue looking back. When Lian Chengyue turned around, he asked, "Why are you turning back?"

Lian Chengyue said: "I always feel like someone is watching me."

Shi Ruzhuo was about to laugh loudly when he suddenly noticed that Lian Chengyue was frowning slightly. Considering that perverts like Lian Chengyue usually don't have much expression changes. So today, he actually frowned, and it was obvious that something was wrong.

He waited for the tutor to come on stage with full of questions. The tutor was wearing a Taoist robe and gold-rimmed glasses. This outfit should have made him look very sage, but between his eyebrows there was a kind of harshness and anger that only frustrated people would have.

He doesn't seem to be in a good mood today.

"Gold-rimmed glasses are the uniform of teachers at Yang Zhishui's cram school." Yang Feng whispered to Ning Mingmei.

To show that they have the same...academic authority as Ning Mingmei.

Ning Mingmei said: "I see, it turns out to be a uniform... hm."

Old Seventeen and Old Eighteen were charged with one more crime: imitating Ning Mingmei's makeup.

Yang Feng:?

Ning Mingmei stared at the teacher again and again, but could not see any signs of Old Eighteen and Old Seventeen transforming. He originally wanted to catch Old Seventeen and Old Eighteen in today's class to obtain direct evidence of misappropriating his intellectual property rights, but it seems that he will not be able to achieve this goal today.

System: “Very disappointed?”

Ning Mingmei: "I'm very pleased. Old Seventeen and Old Eighteen have also learned to be their own bosses and have hired workers to take classes as substitutes. They have learned a lot from me."

system:……

The teacher glanced at everyone and asked, "What are you two doing?"

Yang Feng's shoulders trembled - Teacher Tan seemed to be in a bad mood again today.

Tan Shi is an inner disciple working in Sikong Hall. Logically speaking, Sikongtang should have plenty of money. But he was aloof and arrogant by nature, and offended many people early on. Therefore, he has always been depressed and resentful, thinking that he should be more than that.

But in terms of cultivation, Tan Shi is very outstanding. Sikongtang often repaired buildings for Ningmingmei, so Lao Shiqi often had some contact with them. When he started his business, he saw that Tan Shi was being ostracized by the people in Sikongtang, so he kindly invited him to join in, wanting to give him a hand. At the beginning, Tan Shi was also very moved and worked hard.

But as time went on, the conflicts between them became increasingly acute. Tan Shi's mood became worse and worse, and his attitude towards his disciples was not much better.

Everyone stood up in unison - Ning Mingmei was dragged up by the young man next to him. He stared at the group of young girls and boys bowing respectfully to the teacher: "Hello, teacher!"

Tan Shi: "Sit down. Where's the squad leader?"

Under the watchful eyes of the crowd, the young man sitting in the first row stood up again. He has picturesque features and a gentle temperament: "Hello, teacher."

"Please hand out the homework books from last time."

Lian Chengyue is doing well. He has even become the class monitor of the cram school.

The boy was distributing exercise books, and along the way, many girls and boys cast favorable glances at him. Ning Mingmei supported his chin with one hand while watching, his cat's eyes becoming a little bored and empty.

Yang Feng also received Ning Mingmei's homework book. The comment was actually "excellent", it seemed that Yang Feng's performance was really good. Ning Mingmei heard Tan Shi say at this moment: "Where is Yang Feng? Why are you sitting in the back today? Is the one next to you... a new classmate?"

Yang Feng: "Yes. I'll take him..."

"Oh, new student, please write your name on the sign-in sheet later," said the teacher.

Ning Mingmei was sitting in a position that was backlit. The teacher couldn't see his face clearly, but it was common for cram schools like Yang Zhishui to have temporary transfer students. There were also a few curious disciples who looked around, trying to get a clear look at the face of the new transfer student.

Only Lian Chengyue was sitting in the first row at this moment, with his back straight - he was busy studying and had no time to look at the transfer students.

"An alchemy practitioner pours three pounds of water into the alchemy furnace every hour. However, what he doesn't know is that a demon practitioner releases half a pound of water from the small hole under the alchemy furnace every hour. The total capacity of the alchemy furnace is... How long will it take for the alchemy practitioner to fill the alchemy furnace?"

"A sword cultivator was fighting with a great demon. They both started from Yaochuan City at the same time. The demon cultivator fled to the demon world at a speed of... The sword cultivator's speed was... However, after escaping to the demon world, the demon cultivator took a knife and quickly returned to fight with the sword cultivator. How long will it take for them to meet?"

…

Lian Chengyue listened carefully, raised his hand to speak from time to time, and after a question caused a lull in the audience, he went on stage and gave his answer.

Tan Shi was strict with others, but he was very satisfied with Lian Chengyue: "Learn from Lian Chengyue. Look at her, and then look at yourselves."

This statement should be very irritating and should attract hatred. But the person being praised was Lian Chengyue after all.

He has top-notch spiritual roots, studies hard, and has a gentle personality. His only shortcoming is that he is a little illiterate, and he also has a little village internet access.

Therefore, the vast majority of people feel admiration and respect. A few people blushed when they saw Lian Chengyue's handsome face - who wouldn't like a top high school student with a beautiful appearance, noble character, and good study skills?

At this moment, several disciples in the audience also showed very unhappy expressions.

Tan Shi heard the unhappy boos from several disciples. He wanted to scold those people, but when he turned around, he saw that the new disciple was holding his chin and staring out the window.

Kill the chicken to scare the monkey. Tan Shi pushed his glasses and said, "In that case, let's let the two of you compete on the next question. Lian Chengyue, you don't need to go down yet."

Lian Chengyue said: "Okay, Teacher Tan."

"If one more person comes up... well, Merlin, it's you."

Merlin, this name is so unfamiliar.

As the disciples were looking around, a young man stood up from the second to last row by the window. The girl closest to him was the first to see Merlin's appearance. At that moment, she actually let out a cry of surprise.

"oh--"

Amid the disciples' low "ohs" one after another, Lian Chengyue turned around holding the chalk and saw the face of the disciple named "Merlin" clearly for the first time.

Black hair, fair skin, slightly pink cheeks and chin, and a pair of cat-like eyes. The owner of the cat's eye looked a little bored. He walked past the crowd and quickly to the podium.

"Classmate, here's your chalk." Lian Chengyue said kindly.

He handed the chalk in his hand to the visitor. The man glanced at him and took the chalk from his hand.

Shi Ruzhuo: "You gave him the chalk?"

Lian Chengyue picked up another piece of chalk from the table, looking very neat.

Tan Shi watched them interacting coldly. Just as he was about to speak, Mei Lin took the lead: "Teacher Tan, do you have any questions?"

Tan Shi: ...Is this a question for me or for you?

This was Meilin's first time attending class, and Tan Shi wanted to show off his power. He then said, "Let's solve a system of three linear equations first. You two can compete to see who can solve it faster. Mei, this is your first time here today, so let's find out the basics. I saw you were looking out the window just now, so maybe you didn't understand what you were learning very well?"

After he finished speaking, he listed a set of questions on the blackboard.

After Tan Shi finished writing, Lian Chengyue turned around and wanted to say "Let's work hard together" to his new classmates. But he saw that the new classmate was already arrogant and started writing on the blackboard with a piece of chalk.

He wrote those keychain-like numbers very beautifully, but it didn’t matter, because Lian Chengyue wrote them in printed form, stroke by stroke.

The chalk dust fell down, and time passed very quickly, and the two of them wrote out the results at the same time. In terms of time, there is not even a single minute difference.

"This question is relatively simple." Tan Shi was a little embarrassed that he had not completed his goal. He turned to the next question and said, "This one is four yuan per time. You guys try it."

The only sound in the classroom was the sound of chalk rubbing against the blackboard. After a while, they both finished the questions at the same time.

The two unexpected things made Tan Shi feel a little uneasy. The sound of students' discussion gradually emerged in the classroom. Because the speed at which the two of them solved the problem was really too fast.

This speed cannot be determined by the level of proficiency in knowledge. It is a kind of speed in mental arithmetic, a kind of sensitivity to numbers, a kind of speed that seems to be able to get the complete answer at a glance. On the one hand, half of the people were shocked at how fast Lian Chengyue was improving - after all, when he first entered Yang Zhishui's cram school, he couldn't even understand numbers. And more people were shocked by this unknown Merlin.

They had never heard of Merlin's name before. Who was this Merlin?

The discussion in the audience actually had nothing to do with Tan Shi. But when Tan Shi stood on the stage, he always felt that the dense voices in the audience were laughing at him. His back began to tingle. Facing the two people beside the blackboard, he said, "It's quite fast, but these are just mechanical calculations. You guys try to solve this system of linear equations with five variables."

After saying that, he copied the question onto the blackboard. Tan Shi stood between the two of them and copied. But Lian Chengyue's gaze passed him and looked only at Merlin.

For a moment, it seemed as if there were only two of them on the podium.

Merlin didn't look at him, but he didn't look elsewhere arrogantly, or stare blankly at the chalk dust on his fingertips. He just tilted his little head and watched Tan Shi's movements with a look of concentration.

Tan Shi wrote faster and faster, and finally, he put down the last stroke and signaled the two to start.

Lian Chengyue picked up the pen and started writing, but Meilin didn't move. Just when everyone thought that Merlin had reached his computing limit at a loss, and Tan Shi was about to start his speech.

The boy spoke.

His voice was pleasant and clear, but the words he uttered surprised everyone: "Teacher Tan, are you going to let us find a numerical solution for this problem?"

Tan Shi said: "Yes, you can't figure it out?"

"Teacher, the system of equations you gave is not rank-full, and all variables are linearly related." Merlin said.

"..." Tan Shi said, "What do you mean?"

At this moment, Lian Chengyue also stopped writing and just looked at the young man beside him. The boy finally picked up the pen and wrote on the blackboard word by word: "I mean, all unit vectors are vectors of this unit vector——"

“They are all solutions to this problem.”

There was total silence. The boy said, "Teacher Tan, you copied the wrong number here."

The last sentence was like the final word.

And Lian Chengyue also looked at the young man again at this moment. The Qingji Sect always said to guard against arrogance and impatience, but after this young man said this, his expression was calm, but the light in his eyes was flying - he was so proud that he looked radiant. Seeing Lian Chengyue looking at him, he just glanced at him and raised his eyebrows.

Without saying a word.

Tan Shi said: "Haha, ha, I just wanted to test your adaptability. In this case, let's just count this question."

Tan Shi was embarrassed in front of everyone, so he simply turned to the second half of the question book in his hand: "Can 3^(2n+2)-8n-9 be divided by 64? I'll give you a hint for this question..."

He is stuck.

Wait, how do you do this question?

Sometimes graduate students are unable to solve the problems that high school students can solve - one reason is that they have forgotten how to do it, and the other is because there are MATLAB, JupyterNotebook, and all the good computing software. This is what Tan Shi is like at this moment.

Before he finished speaking, the young man said, "It's very simple. Just use mathematical induction."

Tan Shi:?

The young man asked, "Do you know what mathematical induction is?"

…

The boy spoke on the stage for ten minutes and left in a cool manner after finishing his speech, just when Tan Shi was on the verge of an outburst.

Tan Shi was about to get angry - until he glanced at Lian Chengyue beside him. This talented young man was surprisingly graceful at this moment. He helped Merlin pick up the chalk he had dropped on the floor and put it back on the table.

There was even an elegant smile on his face.

Tan Shi was immediately deflated - as an adult swordsman, was he not as good at self-control as a teenager?

To this end, he held his breath and worked hard to complete today's course content. After finishing the class, he threw the pop quiz to everyone and left the classroom.

Everyone in the classroom started doing the questions before they had time to wail. Lian Chengyue spread out the test paper and turned to look at the young man sitting by the window in the second to last row.

The boy didn't even look out the window with his chin in his hand. He was holding a pen and writing quickly on the test paper.

“…He’s very strange.”

Shi Ruzhuo: “Ah?”

Lian Chengyue said: "After the course is over, I need to talk to him for a few words."

The existence of this person is an obstacle for him to become the best student in this cram school.

Lian Chengyue suppressed his inexplicably beating heart and finished the small test paper quickly as before.

When he, as the class monitor, collected the test papers, the other students had already gone outside to rest. The disciples who attend Yang Zhishui's cram school practice their body movements on their own every morning, attend classes in the afternoon until the evening, study on their own at night, and take one day off a week, repeating the cycle over and over again. Before the next Chinese class started, Lian Chengyue came to the boy.

Like Lian Chengyue, there are many people who want to be with the young man. But they were still a little afraid and didn't know how to approach him.
