Feng Dexuan understood wrongly: "That's the same, it's not good to trouble people." ”

"Otherwise, you should study by yourself first, and write down what you don't understand. I'll copy the class notes in detail and show them to you, if you don't understand it again, then there is no choice but to ask the teacher. ”

Song Yiyi didn't want to explain to her, so she didn't say anything more.

The people in the car discussed about it, and the car also drove to the mouth of the alley.

Song Yiyi smiled at Feng Dexuan, Ma Yuanshan, and Cao He: "It's troublesome, I'm going to play my role." ”

The three of them also laughed, and after half a day's work, the relationship naturally became a lot closer: "You hurry up and go home and lie down." ”

"When I go back to school today, I'll help you ask for leave!"

Song Yiyi was just about to get up, but remembered something: "Brother, you went to the Public Security Bureau to remind the case that the 100 yuan and a portrait in the hands of the gangsters can be used as evidence." After handing it in, try to keep people touching it with their hands as little as possible. ”

Seeing that everyone showed puzzled expressions, he explained: "If the person surnamed Tang refuses to confess who instructed him, it is recommended that the public security check the fingerprints on the physical evidence." If the paper used for the portrait had Jing Ningyi's fingerprints on it, it would not be easy for him to get away with it!"

"Even if he's not the principal, he's an accessory! ”

Song Yiyi and Song Zi'an glanced at each other, and Song Zi'an immediately understood what his sister meant, the real punishment is not on the surface!

When Song Yiyi got out of the car and walked into the alley, Jiang Xinyong stepped on the accelerator and went straight to the Municipal Public Security Bureau.

Feng Dexuan admired Song Yiyi's mind very much, looked at the old man, and easily thought about it, and he could think of fingerprints.

But there is still something she doesn't understand: "I've heard that everyone's fingerprint is different. But how can fingerprints on portraits and coins be extracted?"

Ma Yuanshan and Cao He didn't know anything about this, frowning and trying to think of a way.

Song Zi'an taught him this knowledge when Grandpa Song and Grandma Song taught him the high school curriculum step by step, but it was only a passing one.

Seeing that no one answered, he took the initiative to say: "It is to spray a chemical solvent on the fingerprint blot, and after a series of chemical reactions, the fingerprint will be clearly revealed." ”

Ma Yuanshan put his hand on the seat in front of him, leaned forward, and spoke to Song Zi'an, who was sitting in front of him, with a sideways face: "It's chemistry! Actually, when I was reviewing for the college entrance examination, I was quite interested in physics and chemistry, but I didn't have enough time to learn them by myself, hey!"

Song Zi'an knew that the three people behind him were all classmates who helped his sister today.

Although my sister didn't need the help of others to deal with those little gangsters, she took 10,000 steps back, she couldn't run, if she really ran, ordinary and ordinary people couldn't catch up, but he was still grateful to these three people.

So, he half-turned around and smiled at Ma Yuanshan: "Actually, if you learn Chinese medicine well, both yourself and your family will benefit for life!"

"If you really like it, think of it as your hobby. ”

Being so close, Ma Yuanshan saw it very clearly, and sighed secretly in his heart: If you look at it from a distance just now, you can know that this person is good-looking, can it be bad! Song Yiyi's own brother, as long as the brother and sister are a little similar, then this brother will look good. Now take a closer look, good guy, a boy, how can his skin be so good!

Ma Yuanshan blinked, retracted his gaze, and always stared at others like this, which was too rude: "Actually, I really went to the bookstore, and I wanted to buy a few books on physics and chemistry and science, and it would be good to know more about some superficial knowledge, but unfortunately there were basically none." ”

"It's all textbooks or exercise books, and I don't plan to learn them in depth, but now I can't read those boring formulas and principles at all, hehe. ”

Song Zi'an felt that this little favor could still help: "You give me the address of your school, my grandfather and grandmother are engaged in physics and chemistry, I will write to them, and if there is such a book, I will send it to you." ”

Ma Yuanshan didn't expect that Song Zi'an would be able to help when he met for the first time, this is really a real person, and hurriedly thanked: "That's really good, thank you." ”

Song Zi'an looked as warm as jade, and he had already looked at Feng Dexuan dumbfounded. She has always had a crush on this type of person.

Feng Dexuan was bubbling in her heart: her brother is a military cadet, that is, although he looks elegant, he is actually not a weak scholar, but has a force value, and may be quite powerful!

Feng Dexuan stabilized his mind, his friend's brother should not be bullied! He is a principled person, so what should he do...... Since it's the elder brother, isn't it also my brother!

Thinking of this, Feng Dexuan, who thought he had solved the problem perfectly, looked at Song Zi'an with confidence.

Cao He was not willing to lag behind and joined the conversation: "I have long heard that Song Yiyi has an elder brother, and he is really a talent when I see it today!"

Song Zi'an knew that he had nothing to say, so he also released his kindness and greeted him.

Cao He suddenly remembered a question, because the atmosphere of the chat just now was too good, and he asked with a bald mouth: "Brother Song, how old are you this year? I am twenty-four years old this year." It's enviable to look at the kind of person you should be young!"

Song Zi'an's eyebrows didn't move, but the corners of his mouth were slightly upturned: "It's not that I look young, it's that I'm really young, I'm nineteen years old this year." ”

Cao He was surprised, and thought about it for a while, this is reasonable, my brother is three years older than my sister, what a reasonable thing.

Ma Yuanshan was also surprised: "We really made a fuss, Brother Song Yiyi, you are two years younger than me!"

Feng Dexuan, who is conservative in her heart, is even more wailing in her heart, her brother is actually three years younger than herself, he is a little brother, oops, it's really unexpected!

Suddenly, that surging girl's feelings were blown away by the strong wind and disappeared without a trace!

Besides, Song Yiyi walked home quickly, and sure enough, she saw that Luo Jinhuan had already put on her coat and was about to go out. Hurriedly stepped forward and shouted, "Master, I'm back, are you in a hurry?"

Luo Jinhuan looked at Song Yiyi: "No, how long has it been since school was out! What happened to you today?"

Song Yiyi and Luo Jinhuan entered his room, and they didn't hide it, and told them all about what they encountered after school.

Luo Jinhuan's face turned pale: "This family is simply shameless! I'll go to Jingquan's leader to ask how he educated the child!"

Song Yiyi grabbed Luo Jinhuan in anger: "Master, don't be angry, my brother and I will clean him up, don't you get angry!"
