Police Detective

　　 "It's okay." The uncle couldn't help but glanced at Bai Song: "You still minor in chemistry in college?"

　　 "We have these courses, but mainly biochemistry, forensic basic courses." Bai Song did not shy away.

The police academy’s courses are quite interesting. Generally speaking, if you are an investigator, in addition to this major, you have to learn a major course in other majors, and if you are in another major, you should also learn an investigation. The main lesson, and so on.

　　 "You don't look like a person from Tianhua City?" the uncle asked.

　　 "Well, from Shandong Province."

"No wonder, the foundation is pretty good." The uncle took out a few more books: "These are the basic theories of the university. It is a textbook left by a student of mine. In addition, the university also needs to study structural chemistry and chemical engineering. Why? So, are you interested in reading?"

　　 "Yes." Bai Song nodded, still curious about this knowledge.

　　 "Haha, yes, it's rare for someone who likes to read." The uncle handed the inorganic chemistry book to Bai Song: "Come back and find me after reading it."

　　 Bai Song nodded, and when the judicial examination is over, there will be other things to watch.

　　 "By the way, uncle, don't you know what your name is?"

　　 "My name is Tang."

　　 Bai Song nodded, he can no longer be called the uncle, he must be called Tang.

　　 呸 呸 呸, Mr. Don.

　　 I didn't have much to gain from a trip. I only got such a book, Inorganic Chemistry.

Back at the work, Bai Song flipped through the book. This book is actually nothing precious. You can buy it for dozens of dollars on the Internet, but the dense notes on it are really amazing. After reading a few pages, Bai Song is a bit speechless. .

　　 I can understand the book, but I can’t understand the notes. What is the experience?

　　...

　　 For the time being, I put away the book that has increased its value many times due to notes. Bai Song has nothing to do. After busying with several other cases in the past few days, he took the time to read the exam book.

　　 There are still 20 days of exams. After the shift tomorrow, I have to go to Beijing. Ma Zhiyuan sent his sister to school. Bai Song will check it out anyway.

　　 These months have been the most fulfilling months for Baisong. When time goes by faster and faster, and once you look back at the past years, once you find that you are not wasteful, you will have a very strong sense of satisfaction.

　　 On the weekend, when Wang Liang heard that Bai Song was going to Beijing, he also asked to go. Bai Song did not object. He was going to drive anyway, so he could enter the city by applying for a permit.

　　 This is the first time Bai Song drove to Beijing. He didn't have much experience. He set off at 7 o'clock in the morning and was blocked on the South Fifth Ring Road at 9 o'clock in the morning. When meeting with Ma Zhiyuan, it was already noon.

　　 too blocked...

　　 This is also normal, you know, the No. 6 highway leading to Shangjing City, there was a traffic jam of 120 kilometers in 2011, the world record of continuous traffic jam for 20 days...

　　 It was the first time that Bai Song saw Ma Zhiyuan’s younger sister Ma Ningning. He heard Ma Zhiyuan say that he wanted to name his sister Ma Ningjing, Tranquility Zhiyuan, but the younger sister didn’t like it, so she called Ma Ningning.

　　 It can be seen that Ma Zhiyuan is very fond of his sister, and this time he is also carrying a large bag on his body.

　　 Bai Song helped to pick up the wind, and moved things by the way, arranged for Ma Zhiyuan and his sister, and drove Wang Liang back at night.

The two originally planned to go back to their alma mater, but it was too congested, so they hurryed back and added WeChat before leaving. Bai Song and Xiao Ma promised that if Ma Ningning had anything to do, they could find him. A worry.

　　 On the way back, Bai Song drove the car and watched Wang Liang’s WeChat chat very happily. Taking advantage of the traffic jam, Bai Song glanced at Wang Liang’s mobile phone: “How old are you than this little girl?”

　　 "Five years old, what's the matter?" Wang Liang answered casually, and then he was taken aback for a second: "?????"

　　 "What did you say?" Bai Song looked at Wang Liang's face with a question mark.

　　 "You have something wrong with me?" Wang Liang was furious: "Who do you think of me?"

　　"..."

"You!" Wang Liang got angry and put his phone aside. Only then did he see the chemistry book on Baisong's car. He didn't know if it was to ease the embarrassment. He said directly: "You don't have the same knowledge as you~www.novelmtl.com ~Reading."

　　 The sky was dark, and the lights on Bai Song's car were better than nothing, and Wang Liang actually read the book.

　　 The corners of Bai Song's raised mouth never let go. Ma Ningning is very cute. Although he is a child from the mountainous area, he has very smart eyes. Although he looks a little rustic now, as long as he has been polished for a year in the university, he is definitely at the school level. It is no wonder that Wang Liang is a turtle .Well, there is nothing wrong with this description, isn't it just for complaining.

　　 "Okay, I don't know if I took the book upside down." Bai Song glanced at Wang Liang, and saw that Wang Liang quickly exchanged the book, only to find that he hadn't taken the wrong direction at all.

　　 "Huh..." This time Wang Liang took a full five or six seconds to sit down, staring at the long dragon in front: "At this speed, when can I go home?"

　　Bai Song didn't care that Wang Liang deliberately changed the subject, he was not a gossip, "Looking at this, it is estimated that it will be eight or nine o'clock in the evening when you go home."

　　 "I never drove a car from here before when I was studying in university, but now I know..." Wang Liang seemed very satisfied with Bai Song's non-gossip attribute: "Go back later, I will invite you to dinner."

　　 "Yes," Bai Song accepted frankly.

　　 "Ha", Wang Liang was very happy: "Why do you still have this book? And I look at it~www.novelmtl.com~ It seems that a girl takes a lot of notes? Who?"

　　 Before Bai Song answered, Wang Liang started gossiping himself: "No, isn't Zhao Xinqiao studying law? Who are you? I can tell you that you can't half-hearted."

　　 "How is your chemistry?" Bai Song did not answer Wang Liang's question.

"Ha, I've studied inorganic chemistry in university, but our major is engineering." Wang Liang felt good about himself, looked at it carefully, and at the first glance, he said, "This is what I went to school. The textbook of the time, my test score..."

"What is this?" Wang Liang turned a few pages, and then read the book cover again: "This is inorganic chemistry????? This note says...PO4 tetrahedron and VO4N triangular bicone share oxygen. Atoms are arranged alternately to form a novel V/P/O inorganic helical chain..."

　　Wang Liang looked confused after reading, "Brother, tell me, is this really inorganic chemistry?"

　　 "Well... Didn't you talk about it later, what is the inorganic chain." Bai Song wrote in a mouthful, "It doesn't deviate from inorganic chemistry anyway, right."

"Okay." Wang Liang continued to scan his eyes, "Okay, I believe you have no gossip. The person who wrote this note is estimated to be ten years older than you... It's strange, how can you use it? This kind of book to take notes..."
