The black car honked its whistle, apparently urging Zhao Ersheng to pass.

However, Zhao Ersheng is still hesitating, obviously, the magic of the bicycle is much greater than that of a car.

"Let's take your dad's car back!" Geng Chaozhong said helplessly.

"Spoiled!"

Zhao Ersheng flattened his mouth, picked up his schoolbag and ran back.

"Remember to teach me how to ride a bike when you have time!"

When he opened the car door, Zhao Ersheng suddenly waved his hand at Geng Chaozhong.

"You're pestering someone to teach you to ride again?"

In the car, Zhao Kezhen, who was sitting in the back seat, had a smile on his face.

Only when he sees his daughter will he take off that taciturn mask.

"yes, this guy is interesting!" Zhao Ersheng's face was full of innocence.

"I think he's a little older than you!"

The car had already turned around, and Zhao Kezhen stared at the back of the young man riding a bicycle in front of him.

"I don't know, I didn't ask, but he's an old-fashioned person, just like you, Dad." Zhao Ersheng smiled.

The sedan had gradually caught up, but before the car could overtake the young man, the young man rode the car and turned a corner, and Zhao Kezhen couldn't help but feel a little regretful.

"How did you meet?" Zhao Kezhen seems to have a small talk without a match.

"I met him in class, and he was the assistant director of the library." Zhao Ersheng said.

She was also looking at the vanished figure in front of her.

Zhao Kezhen noticed his daughter's expression, which was the reason why he inquired about the news - although his daughter was careless, she was not a White Lotus, perhaps out of a father's instinct, Zhao Kezhen would be vigilant against anyone who approached his daughter.

"Well," Zhao Kezhen pondered for a moment, as if thinking about how to phrase it, "Ersheng, college is not as good as middle school, you also know your father's identity, many people may, may approach you for some purpose, can you understand?" ”

"Dad!"

Zhao Ersheng covered his ears, obviously it was not the first time Zhao Kezhen had said this.

"My daughter is not a fool, this person usually ignores me, that is, today, didn't you call me to talk! That's ......."

Speaking of this, Zhao Ersheng suddenly remembered that Geng Chaozhong didn't let him tell his father that he knew him just now.

"Oh, by the way, did you tell the people at the school what I said?" Zhao Kezhen also remembered this incident.

"Tell," Zhao Ersheng seemed to be a little worried, looked at Zhao Kezhen with wide eyes and asked, "By the way, Dad, how do you know that the people from our school went to the back alley of the Japanese Consulate, and there are no marks on them." ”

"Ha, there are so many people in your school, how can I recognize them." Zhao Kezhen laughed.

"And how did you recognize that?" Zhao Ersheng suddenly became curious.

"Guess."

"Hate, you tell me!"

The father and daughter made a fuss for a while, and then Zhao Kezhen spoke:

"I didn't recognize people, I recognized cars."

"Car?" Zhao Ersheng was a little puzzled.

"Yes, Yanda's bicycle is unique, have you forgotten?" Zhao Kezhen laughed, in front of his daughter, he was always so easy to be happy.

"Oh, come to think of it, it's a little different." Zhao Ersheng touched his head with a sudden realization.

"Yes," Zhao Kezhen looked at his daughter with a smile, "The bicycles in Quanbeiping are all similar in style, the height is very short, and the wheels are sparse, which can be recognized at a glance." Only the bicycle of Yanda was imported from the United States by your principal Situ, the beam is very high, the wheel hub is dense, and the bicycle is like a windmill spinning, so we all call it a flower wheel bicycle. ”

"Yes, yes, our Yanda bike is just good-looking! It's like riding a tall horse! Zhao Ersheng's eyes showed a look of reminiscence.

"Guess why American bikes are taller than those in Peking?" Zhao Kezhen asked with a smile.

"Because foreigners are tall! So their bikes are a little bit taller too, am I right? Zhao Ersheng clapped his hands and said.

"Yes, many of the bicycles in Peking are still produced by the Japanese Fuji self-propelled wheel factory, even if they are domestic, they are all imitations of Japanese cars, only American cars look like this, so I recognized them at a glance." Zhao Kezhen said with a smile.

In fact, if he saw other bicycles in the alley, he really wouldn't necessarily let the driver give way, just because he knew that the middle-aged man was Yan Da and his daughter were in the same school, so he showed goodwill - this so-called love house and Wu.

If Geng Chaozhong knew that he was recognized like this, he was afraid that he would have to hit the wall with his head, because he thought it was so complicated!

"By the way, what are you Yan University teachers doing there on bicycles? It wasn't a safe place, and I'd seen people walk through it, just glance inside, and then be dragged in and tortured by Japanese agents. Zhao Kezhen seemed to remember something.

"Teacher? You say that the cyclist is the teacher? Zhao Ersheng's eyes lit up.

"Yes, I am in my forties with a beard, and I am either a teacher or a faculty member," Zhao Kezhen replied casually, suddenly finding that her daughter's expression was a little strange, and asked with concern: "What's wrong?" ”

"It's nothing," Zhao Ersheng quickly shook his head, "I'm wondering which teacher it is." ”

"I don't know, it's quite face-stricken, I know most of the teachers in your school, I haven't seen this person, it should be a newcomer, so I asked you to notify me, so as not to be arrested by the consulate and cause trouble at that time." Zhao Kezhen didn't think much about it and shook his head.

"Are you sure the guy is in his forties and still has a beard?" Zhao Ersheng's eyes were a little puzzled.

"yes, what's wrong?" Zhao Kezhen glanced at her daughter suspiciously.

"Nothing, I didn't find that person either." Zhao Ersheng lowered his head thoughtfully.

...........

Geng Chaozhong didn't know all this, he was now busy getting close to Professor Wu in the physics laboratory.

I didn't go far after going out just now, I bought a few ink clay from the market, and Geng Chaozhong quickly returned to school.

This Professor Wu came back from studying in the United States, responsible for the teaching and experimental work of the entire physics department of Yan University, and almost did not leave the school on weekdays, that is, in the dormitory and the laboratory, reading books, eating, all of which were for the students to do the work, when Geng Chaozhong arrived, Professor Wu was still in the laboratory, holding a steamed bun in one hand and staring at the spectrometer in front of him with the other.

"Professor Wu, I am the associate Zhou Xuanhe of the library, and there are a few new scientific research papers of Dr. Li Qingxian in the library, would you like to take a look?"

Geng Chaozhong asked, standing outside the laboratory.

"Dr. Lee's dissertation?!"

Professor Wu was also only in his thirties, with unkempt hair and glasses, and dressed as a typical nerd, and when he heard Geng Chaozhong say the three words Li Qingxian, he jumped up at once.

Li Qingxian, but a well-known doctor from the University of Illinois, specializing in the study of magnetite crystal magnetism at low temperatures, is the first person to observe the magnetic cooling effect, and is also a Chinese, after returning to China after 33 years of study, he is now the director of the physics department of Soochow University, and is a well-known scientist in the country.

"Yes, I just arrived, I was afraid of disturbing your research, so I didn't bring it here, I just passed by the laboratory, and I will tell you." Geng Chaozhong said with a smile.

"Ahem, if you bring it here, it's over, I don't bother here." Professor Wu was speechless.

"This," Geng Chaozhong hesitated for a moment, and said hesitantly: "Actually, you have already borrowed five books here, and according to the regulations, these books can only be taken out of the library unless a few more books are returned." ”

There is a rule in the library that students can only borrow two books at a time, and the teacher is better and can borrow five, and if you want to borrow more, you can only borrow one and return one.

"Ahem, then what kind of bend are you turning, just say no!" Professor Wu glared at Geng Chaozhong, picked up a few books from the table and stood up, "Dr. Li's dissertation, that's more important than anything else, what is my research?!" Where, take me there! ”

After speaking, he left the spectrometer and walked out, Geng Chaozhong hurriedly let go of the door, but his eyes were fixed on a bunch of keys on the experimental table.

"Let's go! What are you still doing? Professor Wu saw that Geng Chaozhong was still waiting and urged.

"When you're gone, no one will look at the lab." Geng Chaozhong said helplessly.

"That's right." Professor Wu reacted immediately, rushed to the laboratory table with an arrow, picked up the key and locked the door, and then hung the key on the keychain around his waist.

It's just that he didn't realize that the key was not hung on his waist at all, but came to Geng Chaozhong's hand.

"Nerds are good liars......"

Geng Chaozhong muttered to himself, then put the key in his trouser pocket.

Professor Wu was in front and Geng Chaozhong was behind, and the two walked towards the library one after the other, while Geng Chaozhong had already done his hands and feet in his trouser pocket, pressing the keys one by one on the ink in his pocket.

When he entered the door of the library, Geng Chaozhong saw an opportunity and easily hung the key back on Professor Wu's waist.........

.........

When Professor Wu read the book, he saw that at ten o'clock in the evening, several students on duty in the library had already yawned, but Geng Chaozhong glanced at Professor Wu and found that behind the thick glass lenses of this guy, there was still a flash of excitement, and he didn't look like he was going to leave.

Geng Chaozhong was very helpless, but in the library for the past few days, the behavior of these professors has long been strange, to be honest, not only teachers, but also some students often stay up late in the library, which is why the library has to recruit people.

"Ladies and gentlemen, go back first, I'll be here to guard, and I'll be on duty tomorrow according to the arranged shift." Geng Chaozhong commanded.

"Good!" A few classmates packed up their books and left the library.

In the huge library, there were not a few people left, and Geng Chaozhong looked at Professor Wu's appearance of forgetting to sleep and eat, and his heart was slightly moved.

China, it is such a group of people who support the country to stand tall!

It wasn't until twelve o'clock in the evening that Professor Wu stretched his waist and stood up, he glanced at his watch, and then woke up like a dream to find that the surroundings were already empty, and when he saw where Geng Chaozhong was still sitting and yawning, he couldn't help but say apologetically:

"Assistant Manager Zhou, I'm really sorry to delay your rest."

"It's okay, I don't have anything to do when I go back, in fact, you can take these books back and read them."

"I forgot just now." Professor Wu scratched his fluffy hair embarrassedly.

Geng Chaozhong laughed, he didn't mind, and when Professor Wu left, he went upstairs to notify the students who were still studying hard to leave.

As long as the students do not leave, the library management will not take the initiative to notify them to leave, unless the library is cleared after 12 o'clock in the evening.

Geng Chaozhong closed the door and went out, and found that the light was actually on again in the physics laboratory, and he couldn't help but sigh - this Professor Wu is really too diligent, and now it seems that it is easy to steal the key, but it is difficult to enter the laboratory!

........

Early the next morning, taking advantage of the fact that there were not many people in the library, Geng Chaozhong was about to take a moment to go out to distribute the key, but saw Zhao Ersheng walking in with a few books.

However, this little girl is a little strange today, after glancing at Geng Chaozhong, she didn't say hello, she put the book on the table without saying a word and turned around and left, Geng Chaozhong was even more strange in her heart, did this little girl find something?

"Miss Zhao, don't leave yet." Geng Chaozhong opened his mouth and stopped her.

"What's wrong, what's wrong?" Zhao Ersheng's voice was as low as a mosquito, and he didn't dare to look up at Geng Chaozhong's eyes.

"It's not me who has a problem, it's you who has a problem." Geng Chaozhong said.

"I'm fine, I'm just here to return the book, and I'll leave after returning the book." Zhao Ersheng's tone revealed a bit of panic.

Geng Chaozhong sighed secretly, this little girl must have known something, otherwise it wouldn't be like this.

"There is no one in the morning, I'll go out for a walk with you," Geng Chaozhong pointed out the window, "I didn't let you tell your father the reason yesterday, I'll tell you today." ”

"Forget it, I won't listen."

Zhao Ersheng's face was pale, waved his hand, and turned around in a panic and ran.

Geng Chaozhong looked around, and when no one was paying attention, he quickly chased out, only to see Zhao Ersheng running fast in front of him, as if he had encountered something terrible, this rich lady seemed to be really scared.......

However, Yan Yuan was too big, Geng Chaozhong was tall and long-legged, and he chased after her in a few arrow steps, and grabbed her weak shoulders.

"You, don't come here." Zhao Ersheng turned his head and looked at Geng Chaozhong timidly.

"Your dad must have told you something," Geng Chaozhong looked directly at Zhao Ersheng's timid gaze, "That's right, the middle-aged man your dad saw yesterday is me." ”

"I don't know anything, I won't say anything." The little girl shook her head like a rattle.

"You know, but it's not a bad thing, and I'm not a bad person." Geng Chaozhong's eyes were firm.

"My dad said that good people and bad people can't see their faces." Zhao Ersheng trembled his lips and squeezed out a few words.

Geng Chaozhong couldn't cry or laugh for a while, he understood Zhao Ersheng's psychology, he was both scared and curious, this is really a simple and cute little girl.

"But you know I'm not a bad person, otherwise, you wouldn't be here today." Geng Chaozhong had a smile on his face, and gently dragged Zhao Ersheng to the lake.

"You say, I'll listen."

Zhao Ersheng suddenly calmed down, perhaps realizing that Geng Chaozhong didn't dare to do anything to her on campus.

"Sit down!"

Geng Chaozhong pointed to the stones by the lake and sat down first.
