Liu Qianqian's voice is very nice and magnetic, although she just asked politely, and her tone was plain.

"Oh, I was fascinated by reading the book just now, and I don't know how long it has been?" As he spoke, Chen Hao took out his mobile phone.

"It's past ten o'clock, and the door closes in less than half an hour." When Chen Hao looked at his phone, Liu Qianqian had already looked at his watch.

The library closes at half past ten, and the others who left may have come early, left early, and went back to take a shower.

"Well, I'll go back and see it again. Aren't you leaving? Chen Hao thought about it, he couldn't watch much in the past ten minutes.

"I'll leave when I'm done with this question, and I don't plan to borrow this book." Liu Qianqian came here to do her homework, and she put the reference books back after finishing her homework, saving the trouble of borrowing books.

"Oh, I see you're doing math, do you want me to show you this?" Chen Hao noticed that Liu Qianqian was doing math homework.

Tsinghua University, no matter which department or major, mathematics is a subject that must be studied in the first and second years.

"Oh, well, well, I'm sorry for you." Liu Qianqian heard Chen Hao's words, thought about it, there is not much time now, this topic has not been fully understood, if someone helps explain it, it will be much better than finding information by yourself.

After taking Liu Qianqian's homework book, Chen Hao browsed the questions and quickly understood them. As a public subject in the first year of Tsinghua University, he has almost finished reading one-yuan calculus. And Liu Qianqian's homework topic is just the content of the second chapter, about the topic of differentiation.

This course is not very difficult, for the big bull, it is even very simple, too simple. However, girls do have some disadvantages in mathematics, Liu Qianqian is a special student in English, science is not a good subject, about differentiation is an important knowledge point in college mathematics. Maybe you don't understand enough, so it's normal for the question to get stuck.

Chen Hao combined the content of the textbook with the exercises, and after some explanation, Liu Qianqian quickly mastered the practice of the questions. Chen Hao used to be an ordinary student, and he had his own experience with the problems that students of this level would encounter when learning a knowledge point. Now he doesn't have to worry about such a problem, but the head of the analysis is the Tao, so that Liu Qianqian can quickly understand the places that confuse her.

No one who can be admitted to Tsinghua University is mentally retarded in learning. Chen Hao helped her solve the homework problem at once, and sorted out the content of this chapter for her by the way. Liu Qianqian has basically mastered the content of this chapter.

"Thank you, otherwise, I wouldn't have finished my homework today." Liu Qianqian said politely, with sincerity in her tone.

Although it was only ten minutes, Chen Hao's explanation went from shallow to deep, pointed out the key points, and sorted out the whole content, which made her gain a lot. Because of this, Chen Hao's perception has changed a lot.

"No thanks, it's almost time, let's go out first." Helping Liu Qianqian is just out of friendship and help for beautiful women.

"Well, okay, you go first, I'll put the book back and leave." Liu Qianqian said and turned around with the book.

Chen Hao wants to borrow books and register. When the registration was finished and was about to leave, Liu Qianqian came over, and the two walked out of the library together.

"By the way, my name is Liu Qianqian. Still don't know what your name is? When picking up the car, Liu Qianqian suddenly asked.

"My name is Chen Hao. I already knew your name. Chen Hao said with a smile.

Liu Qianqian was about to say something, when the phone rang suddenly, she took it out and looked at it, it was her roommate's phone. raised his head to look at Chen Hao, showed an apologetic expression and said, "I'm sorry, I'll answer the phone, you go first, thank you today." ”

Chen Hao smiled, and saw that Liu Qianqian had already picked up the phone, so he didn't say anything more, and stepped on the bicycle to prepare to go back to the dormitory.

"Hey, Xiao Ling,..., why are you so noisy, where are you?" Liu Qianqian didn't seem to hear what was said clearly, and asked loudly.

"What? So what to do? Liu Qianqian's voice was eager.

Originally, Chen Hao was leaving, but he heard Liu Qianqian's anxious and uneasy voice. He turned around again.

"What's wrong? Is something wrong? Seeing Liu Qianqian's anxious look, Chen Hao asked with concern.

Liu Qianqian was feeling overwhelmed, looking at Chen Hao's concerned look, and said, "My roommate had an accident at the bar, let me hurry over." ”

"What's going on? Why didn't you call the police instead? Chen Hao asked suspiciously. What's the use of calling your girlfriend in an accident at a bar, it's better to call the police first if you have this time.

"I don't know the specifics, she said she was harassed while dancing, and she won't let her go now." I didn't explain it on the phone just now, and I hung up all of a sudden.

"And what are you going to do now?" It's a strange matter, but it also needs to be dealt with.

"Either I'll go over and take a look, or call the police if it doesn't work." Liu Qianqian has never been exposed to such a thing, and she can't think of any way to deal with it.

"Since they didn't call the police, there is no danger. But since they want you to come over, it won't be good if you don't figure things out. Why don't I go with you, it's not safe for you to go to the bar alone. "If you don't know something, forget it, and since you have encountered it, it is not good to treat it as if you didn't see it.

"Is that good? Otherwise, I'd better go by myself. "Liu Qianqian and Chen Hao have just met after all, and they don't want to trouble others. But if I really go there alone, I'm a little worried.

"It's okay, everyone, since you have something, take it as a help." Chen Hao smiled indifferently. Then he asked, "Is it far away?" Is it too late to ride a bike? ”

"It's a little far, over there at the Electric Power University, Xiaoling has classmates who go to school there, so I made an appointment to go over and play." Liu Qianqian explained.

"Oh, in that case, let's drive over there. You pick up the car first, and we'll go there together. ”

"What's the car? I don't have a car. Liu Qianqian thought that Chen Hao asked her to drive, and felt that there was some misunderstanding.

"Oh, I mean I have a car, you pick up the bike and follow me over to pick it up." Chen Hao knew that Liu Qianqian had misunderstood.

"Oh, I'm sorry, but I didn't ride here. My dormitory is not far from here, why don't I go and pick it up? Liu Qianqian looked a little embarrassed.

"Forget it, if you don't dislike it, I'll give you a ride." Chen Hao felt that if he said this to Liu Qianqian, it was really not the rhythm of saving people.

Sitting behind Chen Hao's car, Liu Qianqian looked a little shy. Although it was night, others couldn't see it, but this was the first time I sat in the back of a boy's car, and I always felt a little confused. In college, a man riding a bicycle with a woman always feels like a pair of lovers.

"Is this your car?" Seeing Chen Hao open the door of the Audi, Liu Qianqian asked in a little surprise.

"No, friend. Get in the car first, let's hurry over. Chen Hao shouted.

Northeast Electric Power University, about a few hundred meters away from the south school gate, in a bar called 'Providence'. Two girls and three boys were sitting together, eating and drinking, and chatting happily.

"Tian Haifeng, I have already made an appointment with you, and I regard it as a return to your favor. In the end, I don't care, I won't do anything like this again. If Qianqian knew about this, she would definitely be angry. It was a girl who spoke, and she looked a little good, it turned out that she was Liu Qianqian's roommate Xiaoling.

Xiao Ling and Tian Haifeng are both from Yanjing, and the two were boyfriend and girlfriend in middle school, but they have broken up now. Although they broke up, the two were still friends, and this time they asked out to play, and Xiao Ling brought her roommate Qian Haiyue with her.

Originally, a few people drank together, chatted, and went out to dance from time to time. But chatting and chatting about roommates and school flowers, and then when several men learned that Tsinghua's school flower turned out to be Xiao Ling's roommate, they expressed their hope to make a friend. Xiao Ling was reluctant at first, but in the end, it was Tian Haifeng's identity as a former boyfriend that made Xiao Ling loosen. Xiao Ling also had to use some small means to deceive Liu Qianqian, because she knew that if this was not the case, a good girl like Liu Qianqian would not come here.

Just looking at the exchange of glances between several men from time to time, with obscene expressions and meaningful smiles, Xiao Ling always felt that something was wrong. But since they have deceived Liu Qianqian, we still have to do a little drama later, don't let Liu Qianqian see it, otherwise my friends won't have to do it.

Chen Hao drove very fast, but it took more than ten minutes to come to the said bar. Stopping the car, Chen Hao didn't open the door directly and got out of the car, looked at the door of the bar, and found nothing abnormal, before he said to Liu Qianqian: "Wait a minute, you go in first, I'll follow you, we pretend not to know each other." You look for your classmates, and I'll follow to see the situation. ”

"Oh, good. Then if you don't see the situation right, call the police. I feel like they've met **. Although Liu Qianqian was very worried, with Chen Hao by her side, she was also more down-to-earth, at least there were boys.

"Don't worry, I'll show up when you need help." Chen Hao comforted.

Walking into the bar, the dim lights, roaring sounds, noisy screams, and writhing body made Liu Qianqian feel uncomfortable for a while. She'd never been to a place like this before, and looking at the swaying, obscene action on the dance floor, she wanted to leave right away. But when she saw Chen Hao behind her, she mustered up her courage and walked into the hall.

"Here she is. It was the girl with long ponytail hair, a white shirt, and blue jeans. Xiao Ling, who was sitting in the booth, saw Liu Qianqian come in and reminded him loudly.

A few people looked over, only to see a slender beautiful girl looking around, her impeccable face was nervous and anxious, and the dim light could not hide her stunning demeanor.

Seeing this, several boys couldn't help but swallow their throats, and the ** in their hearts was about to move.
