Just tonight, the professor would work in his office until ten o'clock, and then on his way back to the family home, he was knocked unconscious by two drunken men.

Collapsed in the cold night for two hours, and was finally taken to the hospital by the enthusiastic night returnees.

After treatment, life is worry-free and looks the same as usual.

But ten years later, the professor will accidentally become a demented old man because of the heavy blow to the brain tonight.

Jiang Fan came to ask questions to see if he could make the professor stagger the attack three or four hours later.

After the professor finished the topic, he asked Jiang Fan if he understood, Jiang Fan naturally understood, and concisely said his understanding.

Professor Li nodded when he heard this, and there was a lot of smile on his face, and he seemed to be very satisfied.

Professor Li was very kind to the motivated student, asked him if he was cold, went to get the kettle, and said that it was cold to drink some hot water.

Jiang Fan was sensible, and hurriedly took over the water and boiled water.

At the sound of the kettle, Professor Li asked him to sit, got up and found a book, handed it to him, and spoke.

"Jiang Fan, study hard, I read your homework this morning, and I found that your talent is good, because you answered very rigorously, but I found that I still underestimated you, the question you asked just now is better, which proves that you are still good at thinking, this is especially important, whether it is to engage in scientific research or do business in the future." ”

Jiang Fan nodded to indicate that he was taught, and flipped through the book given to him by the professor in his hand, he had also gotten this book before, but it was only when he was in his junior year, perhaps, at that time, he really entered Professor Li's eyes, but now it has been advanced by nearly two years.

The book is Professor Li's private collection, from mechanical mechanisms to mechanical materials, from mechanical applications to electrical combinations, mixed with a large number of cases and projects, all of which are projects that professors have participated in over the years, which can be called precious.

He flipped through the book and was grateful that this book would allow a robot to have a complete mechanical design idea, and would allow a robot to take at least a few years of detours, standing on the shoulders of his predecessors, and always be able to see farther and go better.

Professor Li explained the general idea of the book and then inspired him.

"Some may not be very well understood, but don't be discouraged, learn slowly, you can come to me, you can also check the information, and you will understand slowly. ”

Jiang Fan nodded, then got up to get the water that had been boiled, and poured a cup for the professor, who asked him if he drank tea, and he was not polite.

After the professor finished explaining, Jiang Fan stood up solemnly and bowed to the professor.

"Thank you, Professor Li. ”

Professor Li waved his hand and asked him to sit down.

Then the two chatted for a while.

In the end, Jiang Fan had to quit and leave, because the professor said that he had to be a little more busy.

After Jiang Fan came out, he stayed not far from the school gate, and in the cold wind, he waited for two hours.

At night, he lit up his phone, and the time showed 10:40 p.m.

He breathed a sigh of relief, since he had taken up the professor for a while, probably tonight's events wouldn't happen again.

Jiang Fan breathed a sigh of relief, but he didn't leave there.

He decided to wait for the professor and watch him get home safely.

He moved his cold hands and feet, but his heart was warm, and it was a very meaningful thing to be able to change his bad luck so that the professor would not be stupid and confined to a wheelchair.

The professor hasn't come out yet, but a stout middle-aged man has come out.

The middle-aged man walked out of the school gate and greeted the tall man who was approaching, the tall man was holding two bottles of wine in his hand, and after the two approached, he raised his head and poured wine.

It was late at night, and in the winter night, there was not a single pedestrian, only two men pouring wine.

Jiang Fan, who was standing in the shadows, was not noticed by the two men, because of the lush greenery at the door, Jiang Fan was standing in the shadows on one side.

Late at night, drunk, two men.

At this moment, countless thoughts in Jiang Fan's mind exploded.

It's not an accident, it's deliberate.

The middle-aged man who came out of the school gate must have been staring at the professor just now, and since he came out, it means that the professor is about to come out.

The two men poured alcohol to find a reason for themselves to beat people: to get drunk and make trouble. Even if he is caught in the end, there is an explanation.

At this moment, he is unprecedentedly calm, and calling the police probably doesn't work, there is no reason.

Even if you make up a reason and wait for the police to arrive, it's too late.

While he was thinking about this, he had already lightened his pace and walked towards the campus.

The two men had finished their wine and walked a little farther away, but it was the only way for the professor to go home.

I didn't walk a few steps into the campus when I saw the professor.

Jiang Fan thought of the words and greeted him.

The professor was a little surprised to see him, but he was relieved to see that he still had the book in his hand.

"Study so late, pay attention to your body. ”

Jiang Fan's face was serious.

"Professor, there's a very strange situation, don't leave yet. ”

The situation is urgent, to make a long story short, Jiang Fan said a little more reasonably based on his own speculation.

It was indeed his guess, because in his previous life, the two drunken murderers tonight were not found in the end, and the final definition of the case was an accident.

Jiang Fan said that he was reading the book given by the professor tonight, and he encountered a problem, and wanted to go back and ask for advice again, and when he met a sneaky person, he paid attention to it, but he was not embarrassed to trouble the professor again.

But when I went back to the study room to read again, I encountered a problem again, and I was unwilling, and I wanted to ask for advice, but I saw that the person hadn't left yet.

It was late, only the light in the professor's office was still on, and he had some thought in his mind, so he stared at the man.

After the lights were turned off in the professor's office, the man quickly walked out of the school gate, met with another person, and began to pour alcohol without saying a word.

Winter night, nearly eleven o'clock in the evening.

Under the street lamps on campus, Jiang Fan's voice was fast and not flustered, mixed with the sound of the wind, and the air was a little unusual.

Halfway through Jiang Fan's speech, Professor Li's face had become ugly.

Through Jiang Fan's words, he already sensed the danger, and besides, he had some guesses.

Where there are people, there are rivers and lakes, and there are rivers and lakes, and there are grievances, Professor Li is not a person who is dedicated to research in the school, he supports his own team, and has participated in many projects in the society.

Generally speaking, people who are touched by their interests will pinch their noses and admit it, because their skills are not as good as others, and at most they feel a little resentful.

But there are always one or two bastards, who are lucky, who do things that are foolish, and who are still proud and think they are smart.

By the time Jiang Fan finished speaking, the professor had already approved Jiang Fan's guess.

"Jiang Fan, your guess should be true. ”

Jiang Fan frowned and asked the professor if he had offended someone.

The professor nodded, simply explaining that it was just a guess and not yet certain.

Jiang Fan thought about it and looked at the professor firmly.

"Then grab those two guys. ”

The professor was stunned for a moment, looking at Jiang Fan's sincere and determined expression, he found that he was still a young man who underestimated the appearance of this student.

When ordinary people encounter this situation, they should want to protect themselves from harm, in fact, Professor Li just thought so.

But this student actually proposed to take the initiative and arrest people.

Jiang Fan's words are not over.

"Professor Li, I'm still scared now, if it weren't for the two people who just happened to bump into them, I don't dare to imagine what they would do, they deliberately drunk themselves, and they will definitely not show mercy when they make a move, then you will be in danger, although you have only taught me for half a year, but I don't want to teach you to suffer a little damage, catch them, find out who is behind the scenes, and punish them with the law. ”

Jiang Fan's words were not sensational, and they were a bit simple and straightforward, but the professor felt the students' heartfelt concern and respect.

The professor was moved, and his gaze at Jiang Fan was also soft and loving.

Professor Li is not a cowardly character, and he naturally wants to catch the person who insults him, but there is no good way.

There is no reason to call the police.

How could he, an old man, catch two middle-aged people?

Jiang Fan was not in his consideration, because there was no reason for the students to follow the teacher into danger.

Jiang Fan looked at the professor and shook his head, knowing what the professor meant.

So he pointed to the security room and quickly explained his method.

The professor was stunned again, looked at Jiang Fan appreciatively, and then probably had an idea in his heart.

Time is urgent, no more nonsense, teaching this kind of intellectual, naturally not the kind of character that is easily humiliating, but also in front of one of his own students.

There was only one security guard in the security room, a strong man in his forties, who was a little drowsy.

The professor briefly explained the situation, and the security guard's eyes lit up, as if he felt that he had encountered a big event, and he had a sense of accomplishment in solving the case and arresting the criminal, and immediately contacted another patrolling security guard, and his tone was a little excited.

"Professor, what do you say, I'll listen to you. ”

According to the method that Jiang Fan said, Professor Li said that the situation was complicated, and there was no reason to go up and arrest people directly, so he could only wait for the other party to strike first, and then there would be a reason.

The middle-aged security guard waited for the professor to finish speaking, and without saying a word, he took off his uniform and changed clothes with Jiang Fan.

This is Jiang Fan's method, let the security guard pretend to be a student, and work with the professor to ensure safety.

He wanted to follow the professor himself, but the professor wouldn't allow it.

Jiang Fan glanced at the sticks in the security room, picked them up, and stuffed the professor and security guards in their clothes.

"In this way, nothing goes wrong. ”

As he spoke, another patrolling security guard also rushed over.

The professor didn't talk nonsense anymore, and went straight out of the school gate with the security guard.

Jiang Fan and another security guard were guarding the school gate, and when they heard the shouting, they rushed over.

As soon as the professor and the two men went out of the door, they saw the two people who were about to commit murder not far away.

The two men approached and began to hurl insults without warning.

"Get out, don't get in the way of Lao Tzu. ”

"Good dogs don't get in the way. ”

Jiang Fan probably understood.

In the previous life, it should have been these two sentences that angered the professor, and the professor should have wanted to reason with them, so they took advantage of the situation to beat the professor.

Even if he was arrested in the end, it was only because of a battle of words.

Jiang Fan was still not at ease, thought about it, and said to the security guard next to him Let's go over now, the security guard didn't think much about it, and followed behind Jiang Fan.
