Meng Lanting had long noticed that this man had not spoken a word since the beginning of the class and kept his head lowered.
He looked a little different from other students.
When he saw him raising his hand, he asked the others to be quiet and signaled him to speak.
The male student stood up and said, "Ms.
Meng, I made a bet with my friend that there is a maze map.
We have to go through all the designated places and finally return to the starting point, limiting the path that cannot be repeated.
My friend said that it can be used Mathematics method is the way to go.
I am too low-level and I have been thinking hard and can't find a solution.
Miss Meng, since you can get the position of teaching assistant, you must be proficient in mathematics.
This kind of question should not be a problem for Miss Meng.
The maze students will be grateful.”
After saying that, without waiting for Meng Lanting's promise, he came out of his seat, went up to the podium, picked up a piece of chalk, waved his arms on the blackboard, opened and closed, and only heard the sound of whizzing, whizzing, and white chalk shavings.
It kept falling, and on the board, there appeared an extremely complicated maze diagram full of dots and circles.
There was a commotion in the classroom, and the students were whispering.
"How about Miss Meng, can you please help me?"
After the male student finished painting, he stood aside and looked at Meng Lanting with a faintly proud look.
Meng Lanting immediately sensed the hostility from the other party.
She remained calm and moved her gaze from the other person's face to the maze diagram he had just drawn, and looked at it for a moment.
"Ms.
Meng, my friend cleared the checkpoint in five minutes."
The male student glanced at the people in the classroom and said loudly.
Time passed by minute by minute.
Meng Lanting remained silent.
In the classroom, the buzz from students' discussions grew louder and louder.
Some have doubts, some are confused, and some are dissatisfied.
When a boy saw Meng Lanting looking at the maze map without saying a word, as if he was in a dilemma, his blood suddenly boiled in his chest.
He stood up suddenly and shouted: "Qin Mingzhuan, you are from the political department, just come here. , and you use such a question to make things difficult for others, what do you mean?"
The male student named Qin Mingchuan sneered: "Zhang Longyi, you are from the mathematics department and you can come, but I can't come.
Not to mention, I also said that I just asked Miss Meng for advice.
If she can't figure it out, say Just one word, where are the things that make things difficult?”
There was a loud noise in the classroom, and the relaxed atmosphere just now was gone.
Feng Kezhi didn't know where he got his patience.
He came here because of Lao Yan's words, and then he actually stood on the walkway leading out of the back door of the classroom for almost the entire class.
In front of him were seven or eight students who, like him, had no seats and were standing at the back door to listen.
Everyone's attention was attracted by the young lady with short hair on the podium in the classroom.
No one noticed his presence.
Everything was originally pleasant.
Until this moment. finally here Feng Kezhi's gaze went beyond the seven or eight heads crowded together in front and fell on the young girl in the classroom.
She tilted her face slightly, with a tuft of short black hair sticking smoothly to one side of her jade-like face.
A bright ray of sunlight was shining in from the glass window on one side of the classroom, shrouding her in the middle.
Her eyes kept falling on the maze diagram on the blackboard.
The figure cast by the light remained motionless, as if frozen.
"Assistant Meng, if you can't figure it out, just tell me.
I don't mean anything else, I'm just a little sorry."
The male student named Qin Mingchuan was ready to express the ridicule in his words.

Feng Kezhi's eyes suddenly flashed with a fierce look, and he walked forward to the back door of the classroom.
He raised his hands and was about to push away the students blocking his way.
Suddenly he saw the girl turn around, raise her hands, and signal to the classroom.
The person inside kept quiet and then said: "This classmate, I don't know what so-called mathematical method your friend used to get through this maze in five minutes."
"In fact, let alone five minutes, even if you give him five years, ten years, or even die of old age, he will not be able to get through this maze according to the conditions given."
The classroom that was noisy just now suddenly became quiet.
Qin Mingchuan obviously didn't believe it, and said with a smile: "I'm afraid Assistant Meng couldn't figure it out, so I said that on purpose."
Meng Lanting smiled and pointed to the maze on the blackboard.
"This maze looks very complicated, but no matter how complicated the figure is, if you want to follow the requirements just now, you must meet two conditions at the same time."
"The graph must be connected.
Secondly, the number of odd lines connected to a position in the graph, also known as singular points, must be 0 or 2.
Either none, or at both ends.
This is a necessary and sufficient condition for solving the problem ” She turned to the maze on the blackboard.
"In this maze, although the shapes are connected, all eight points are singular points.
In other words, no matter how long you walk, there is no solution as you call it.
I'm curious, who is your friend?
Can anyone tell me his name?
I would love to ask him how he mathematically navigated this maze."
Feng Kezhi stopped.
There was silence in the classroom.
The boy named Qin Mingchuan gradually shed a layer of hot sweat on his forehead and said hesitantly: "In short, he has solved it."
The students seemed to understand a little bit.
"Qin Mingchuan, whose instructions did you listen to to deliberately cause trouble?"
a boy scolded.
Qin Mingchuan wiped the sweat from his forehead and moved towards the door step by step.
Suddenly he took a lunge and ran for the door, leaving a boo in his wake.
Meng Lanting ignored the escaped person and only said to the students in the classroom: "Actually, this problem is very old.
The Seven Bridges Problem of Königsberg in the 18th century is the originator.
Because of this theory, new mathematics has also been developed.
Branched graph theory and topology.
Especially topology, great progress has been made in the field of European and American mathematics in recent years.
If you are interested, we will talk about it later when we have time."
As she finished speaking, the bell rang for the end of get out of class.
"get out of class is over" she laughed.
The students in the classroom applauded again.
Meng Lanting bowed to the students in return, and the applause became even more enthusiastic.
After things calmed down, many students still refused to leave.
They came over to surround Meng Lanting, talking all over the place and asking her questions of all kinds.
"Ms.
Meng, do you have a boyfriend?"
A boy who was usually glib asked suddenly.
Without waiting for Meng Lanting to answer, he added: "There is a saying in Peiping that Peking University is old and Normal University is poor, but Tsinghua University is a good husband.
It says that male students at Peking University are generally dull, and normal university students are from poor families.
Only Tsinghua University, male students Students are rich and interesting, and are the best candidates for boyfriends.
They are the most popular among female students.

In Shanghai, the male students from our Zhihua University are equivalent to those from Tsinghua University.
If Ms.
Meng doesn’t have a boyfriend yet, she might consider it.
Our most beautiful male student” After he finished speaking, the girls in the classroom booed in disdain, while the boys were excited and agreed.
Meng Lanting put away the lesson plan and said with a smile: "Thank you for your enthusiasm.
I haven't considered it yet.
You students should pray that your absenteeism can escape the professor's roll call."
There was laughter again in the classroom, and the students finally dispersed reluctantly.
"Congratulations, Miss Meng.
Your class was great.
The mathematics department has not felt such vitality for a long time."
Meng Lanting heard a burst of applause, and then the words came.
He turned around and saw Xi Songzhou standing at the front door of the classroom, looking at him with a smile.
Meng Lanting said: "I barely passed it and completed the scheduled lesson plan.
I really can't deserve your praise.
Mr.
Xi, please stop making fun of me."
"I mean it, your class is great.
I'm sure you'll be very popular with the students soon."
Meng Lanting thanked him with a smile.
Xi Songzhou also knew that the political student surnamed Qin in class was deliberately making things difficult, and said: "That political student may have been ordered to come here.
But don't be afraid, he was resolved in your class today, so he should Don't dare to do it easily again It's a violation of the rules.
I will pay attention to it in the future.
If you encounter any abnormality again, remember to tell me immediately.
I will go to them to make it clear and put an end to this.
This is not only a way to make things difficult for you, but also for the sake of the school.
Disturbances of order cannot be tolerated.”
Meng Lanting was actually very clear in his heart.
Nine times out of ten, it should have been done by the person who failed the exam with him this time.
Although he is not afraid of shadows when he is upright, it is still a headache if he is always secretly watched by such villains and has to be careful of being tripped from time to time.
After hearing what Xi Songzhou said, he smiled and said thank you.
Lao Yan just followed him and stopped at the back door of the classroom.
Suddenly he saw Xi Songzhou coming over, chatting and laughing with Miss Meng, and hurriedly said: "Ninth Young Master, do you want to go say hello to Young Master Xi?"
He turned his head and found that his young master had turned around and strode away.
His back disappeared around the corner of the corridor.
He was stunned for a moment.
He turned back again and found that Meng Lanting had taken the lesson plan and was coming out of the classroom with Xi Songzhou.
After leaving, he hurriedly chased after her and shouted: "Miss Meng" Meng Lanting was listening to Xi Songzhou talking about a fund-raising event to be held by the school next week to expand the library.
Suddenly he heard someone calling him from behind.
He turned around and recognized the Feng family's driver, Lao Yan, and was slightly startled.
Then he smiled, turned around and stopped: "Uncle Yan."
Lao Yan quickly walked up to her and bowed: "Don't take it seriously.
Just call me Lao Yan, Miss Meng."
After saying this, he also greeted Xi Songzhou who stopped with him, turned to Meng Lanting and said, "Miss Meng, The master asked me to deliver the things you left in Nanjing.
Wherever you live, I can deliver them directly to your door."

Meng Lanting gave the address of Professor Zhou's home on Difeng Road where he currently lives.
Lao Yan took note of it.
"Has the Ninth Young Master also returned to Shanghai?"
Xi Songzhou asked Lao Yan.
"The Ninth Young Master who just returned last night was here just now."
As Lao Yan finished speaking, he suddenly remembered the previous instructions he had received, glanced at Meng Lanting, and swallowed them back.
Meng Lanting listened to Xi Songzhou and Lao Yan say a few words, waited nearby, and waited for the two to finish speaking before thanking Lao Yan.
"Then she left."
Lao Yan came out of school and described in detail the process of his meeting with Miss Meng and Xi Songzhou.
Seeing his silence, he hurriedly emphasized: "Ninth Young Master, don't worry, you don't let me mention it.
I just said half a sentence in front of Miss Meng."
I didn’t say you were here too.”
Feng Kezhi looked indifferent and said nothing.
He stepped on the accelerator and the car sped away.
He first sent Lao Yan and those things to Difeng Road.
Half an hour later, it stopped at the train station of the Shanghai Military Police Corps in Longhua. before the door. gd1806102:
