Wizard of science

"This test? No." Vice Principal Mira answered simply, looking at Dale Duncans and saying, "He didn't go to most of the tests in the courses. Although he went to the tests in a few courses, he only went to the test." He took one look at the test papers and left directly. He had failed in all these courses."

"Is Professor Flo's astrology and Professor Moko's arithmetic the same?"

"Yes." Mira nodded, "I also specifically told this distinguished guest that I hope he can attend, but he just showed up and left without even writing his name. To be honest, I can't even imagine it. , these two lecturers with bad tempers know what this situation will look like."

"Try to appease him as much as possible." Duncans said calmly, looking unconcerned. "It seems that our Mr. Li He is indeed a bit special. But after all, he brought the first generation of Duncans' ring. As long as he doesn't cause big trouble, , let him do whatever he wants. Normally, Ms. Mira, if you pay more attention, tell me in time if there is any special situation."

"Okay, principal." Mira responded and turned to leave.

When he was about to reach the door, he suddenly thought of something. He stopped, turned his head and looked at Duncans and said: "By the way, Principal Duncans, there is one thing, a little thing about our Mr. Li He during the test. Originally, I don’t want to say it, but I thought you might want to know about it.”

"oh?"

"This Mr. Li He submitted blank papers for all course tests, but there was a trace left on the arithmetic test paper given by Professor Moko."

"Did he answer the question?"

"No, he changed the question."

"Changed the question?"

"Yes." Mira nodded and explained, "The arithmetic test paper was given by Lecturer Moko himself. The last question is to prove a certain result. It roughly seems to prove that a traveler wants to travel several towns, and the shortest time is 23 days. , write down the proof process. But our Mr. Li He did not make any proof, but crossed out 23 days and changed it to 18 days."

Duncans frowned slightly after hearing this: "Our Mr. Li He is really interesting. Can you find his test paper? I want to take a closer look."

"Okay, I'll go look for it." Mira nodded and left.

Duncans sat behind the desk, thought for a moment, shook his head slightly, and saw that Mira had not come back for a long time. He stopped waiting and continued busy reviewing documents.

…

Time passes and night falls.

After Duncans finished reviewing the last office document, he stood up from behind his desk, moved his somewhat rigid body, looked at the window next to him, and found that it was already evening.

"It's been so long..." Duncans gently thumped his waist and whispered.

At this time, he glanced at the corner of the table, where there was a piece of papyrus. When he took it over, he found that it was Li He's arithmetic test paper. He didn't know when Mira found it. He didn't notice it at all. .

After a brief glance, he found that it was exactly what Mira said. Li He didn't even write his name on the entire test paper, but only changed the title of the last proof question.

"What's this?" Duncans couldn't help but smile. After a hard day's work, he was too lazy to think about it. He put down the test paper and walked outside, preparing to return to his residence and take a good rest.

In his opinion, Li He, the person who holds the original Duncans' ring, is indeed very special, but as long as he doesn't cause any trouble to Renza University, it doesn't matter. He and the University of Renza were accommodating enough to accommodate a special guest.

With this thought in mind, Duncans walked to the door and took one foot out, but the other foot stopped in mid-air and did not fall down for a long time.

He turned his head and looked at the blank test paper on the table, his eyes flickering. After a few seconds, he turned back and carefully read the proof questions that Li He had revised.

The question was not complicated. Duncans already understood it after reading it once, so he picked up a blank piece of papyrus and began to calculate.

After a while, at the end of the calculation, a result appeared - 23.

"It is indeed the 23rd day. Lecturer Moko personally set the questions. There shouldn't be any problem. It is indeed that I have overthought it." Duncans smiled at himself, put down the pen and paper and prepared to leave.

But after not taking a few steps, he came back with a deep frown, holding a quill and calculating quickly again.

"No, no... There is another solution to Lecturer Moko's question. The traditional answer is 23 days, but if another solution is used, it should be..."

"Shashasha..."

Duncans wrote quickly, and in a moment a new result came out - 21.

Seeing the result of his writing, the corner of Duncans' mouth twitched.

twenty one?

So was he wrong, or was Lecturer Moko wrong?

or……

Duncans looked at the modified 18 on the test paper and felt that the number was particularly dazzling, making his eyeballs hurt.

He took a deep breath, reorganized his thoughts, and calculated again.

21…21…21…

Several times in a row, he got the result 21. Duncans pursed his lips and fell into a long silence while looking at the papyrus.

After a few minutes, he exhaled, walked to the window next to him, and pulled a rope with a blue tie.

"Jingle Bell!"

The bell connected to the rope rang. After a while, the office door opened, and the old butler Balin appeared: "Sir, do you have any orders?"

"Go and invite Lecturer Moko over."

"Lecturer Moko? Now?" The old butler Balin confirmed with some surprise, "His temper is very weird. It's not working time now. Can I call him?" The old butler Balin still knows this lecturer Moko very well. His academic level is very high, but his temper is very bad. When he loses his temper, no one will give him face, including Principal Duncans.

Duncans also understood, rubbed his brows and said, "If you have a nicer attitude, just tell him that you have something important to do with him."

"Okay, then I'll give it a try." The old butler Balin turned and left.

…

After a while, rapid footsteps sounded from outside the door, accompanied by Bahrain's voice: "Mr. Moko, please slow down, slow down..."

"Why should I be so slow? Duncans is looking for me, and I'm still looking for him. Where did he find this group of students? They are becoming more and more outrageous, and he is becoming more and more disrespectful of me as a lecturer... hum... …”

Following the sound, a one-meter-five-headed little old man walked into the office angrily.

He had thin hair, triangular eyes, and a flat nose. He was wearing a gray vest with the buttons crooked, and his face was full of anger.

"Principal Duncans!" After walking through the door, Moko walked quickly towards Duncans and asked unceremoniously, "The number of students in the university is getting worse. If this continues, I doubt if I can stay. What’s the point? It’s probably a pure waste of time.”

"Don't be anxious yet, Lecturer Moko." Duncans smiled and pointed to some papyrus on the table, "Take a look at this first."
