"Of course." The old man couldn't help but look at Bai Song with admiration: "You also minored in chemistry in college?"
"We do have these courses, but they are mainly biochemistry, which is taught in the basic forensic courses." Bai Song did not shy away from it.
The courses in the police academy are quite interesting. Generally speaking, if you are studying criminal investigation, in addition to the courses in your major, you have to take a main course in other majors. If you are studying other majors, you also have to take a main course in criminal investigation, and so on.
"You don't look like you're from Tianhua City?" the old man asked.
"Yes, from Lu Province."
"No wonder, your foundation is pretty good." The old man took out a few more books: "These are all basic university theories. They are textbooks left by one of my students. In addition, you have to study structural chemistry and chemical engineering in college. How about it, are you interested in reading some books?"
"Yes." Bai Song nodded, still very curious about this knowledge.
"Haha, not bad. It's rare to find someone who loves reading." The old man handed the inorganic chemistry book to Bai Song: "Come back to me after you finish reading it."
Bai Song nodded and said that after he finished the judicial examination, he would have other things to read.
"By the way, sir, I still don't know your name."
"My last name is Tang."
Bai Song nodded and said that from now on he could no longer call him "uncle", but had to call him "Old Tang".
Bah, bah, bah, Mr. Tang.
I didn't gain much from the trip, except for this book, Inorganic Chemistry.
After returning to the office, Bai Song flipped through the book. This book was actually nothing valuable and could be bought for just a few dozen dollars online. However, the densely packed notes on it were really amazing. After reading a few pages, Bai Song was speechless.
What is it like to be able to understand the book but not the notes?
…
Bai Song put away the book for the time being, whose value had increased many times because of his notes. There was nothing else he could do. After being busy with several other cases in the past few days, he took the time to read the exam books.
There are still 20 days left before the exam. After finishing my shift tomorrow, I have to go to Shangjing City. Ma Zhiyuan is sending his sister to school, so Bai Song has to go and see her no matter what.
These few months are the most fulfilling months for Baisong. As time passes faster and faster, once he looks back at the past years and finds that he has not wasted his time, he will have a strong sense of satisfaction.
On the weekend, when Wang Liang heard that Bai Song was going to Shangjing City, he also asked to go. Bai Song did not object. He was going to drive there anyway, and he could enter the city by getting a certificate.
This was Bai Song's first time driving to Beijing, so he didn't have much experience. He set off at around seven in the morning and was stuck on the South Fifth Ring Road at around nine in the morning. By the time he met up with Ma Zhiyuan, it was already noon.
Too congested...
This is normal. You know, in 2011, Highway 6 leading to Shangjing City had a traffic jam of 120 kilometers and a world record of 20 days of continuous traffic jam...
It was the first time that Bai Song met Ma Zhiyuan's sister Ma Ningning. Ma Zhiyuan said that he originally wanted to name his sister Ma Ningjing, which means Ningjing Zhiyuan, but his sister didn't like it, so he called her Ma Ningning.
It can be seen that Ma Zhiyuan dotes on his sister very much. This time he came with a lot of bags on his back.
Bai Song helped to pick up the wind and moved things. He also made arrangements for Ma Zhiyuan and his sister. He drove Wang Liang back home in the evening.
Originally, the two planned to go back to their alma mater, but there was so much traffic, so they hurried back. Before leaving, they added each other on WeChat. Bai Song and Xiao Ma promised that if Ma Ningning had any problems, she could contact him, which put their mind at ease.
On the way back, Bai Song was driving and watching Wang Liang happily chatting on WeChat. While stuck in traffic, Bai Song glanced at Wang Liang's phone and asked, "How many years older are you than that girl?"
"Five years old, what's wrong?" Wang Liang answered casually, then froze for a second: "???????"
"What did you say?" Bai Song looked at Wang Liang with a question mark on his face.
"Are you sick? Are you trying to trick me?" Wang Liang was furious. "Who do you think I am?"
“…”
"You!" Wang Liang was angry and put his phone aside. He then saw the chemistry book on Bai Song's car. He didn't know if it was to ease the embarrassment, but he said directly: "I won't argue with you. Read the book."
It was already dark, and the lights on Bai Song's car were better than nothing. Wang Liang actually started reading a book.
Bai Song's raised mouth corners never dropped. Ma Ningning is quite cute. Although she is a child from the mountainous area, her eyes are extremely lively. Although she looks a little rustic now, as long as she spends a year in college, she will definitely be a school beauty. No wonder Wang Liang, a country bumpkin... Well, there is nothing wrong with this description. Aren't brothers used to complain?
"Okay, you didn't even know you held the book upside down." Bai Song glanced at Wang Liang, only to see Wang Liang quickly switch the book over. During the process, he realized that he had not held it in the wrong direction at all.
"Hmm..." This time Wang Liang took five or six seconds to sit down and stared at the long queue in front of him: "At this speed, when can we go home?"
Bai Song didn't care that Wang Liang deliberately changed the subject. He wasn't a gossipy person. "Looking at this, I guess he'll be home around 8 or 9 in the evening."
"I never drove from here when I was studying in college, but now I know..." Wang Liang seemed very satisfied with Bai Song's non-gossiping nature: "I'll treat you to a meal when we get back later."
"Okay," Bai Song accepted it calmly.
"Ha," Wang Liang was very happy. "How come you still have this book? And from what I see, it seems that a girl took a lot of notes. Who?"
Before Bai Song could answer, Wang Liang started gossiping: "That's not right. Didn't Zhao Xinqiao study law? Whose is this? I'm telling you, you can't be indecisive."
"How are you in chemistry?" Bai Song did not answer Wang Liang's question.
"Ha, great! I studied inorganic chemistry in college, and our major is engineering." Wang Liang felt good about himself and read it carefully. After the first glance, he said, "This is the textbook I used when I was in school. My test score..."
"What is this?" Wang Liang flipped through a few pages and looked at the cover again: "This is inorganic chemistry??? This note says...PO4 tetrahedrons and VO4N trigonal bipyramids are alternately arranged through shared oxygen atoms to form a novel V/P/O inorganic spiral chain..."
Wang Liang was confused after reading it. "Brother, tell me, is this really inorganic chemistry?"
"Hmm... didn't you say it later? Inorganic chains." Bai Song made up a story: "Anyway, it's not separated from inorganic chemistry, right?"
"Okay." Wang Liang continued to glance at it. "Okay, I believe you don't have any gossip. The person who wrote this note is probably ten years older than you... It's weird. Why would a big shot use this kind of book to take notes..."
