The person Jiang Nianfeng went to find was his childhood sweetheart's playmate, when she was a child, her family lived next door, and the two had been studying in the same school until they went to high school, and the girl's father was also her father's colleague, so the two families were also very close.

The girl's name is Bai Jialu, and the friends who played with her when she was a child all called her "fake deer", only Jiang Nianfeng called her "Lu Lu", and why there is a deer in the name, and later Bai Jialu and Jiang Nianfeng said, and the rest can't remember clearly, I only remember that her parents knew her because of Li Bai's "Visiting Dai Tianshan Taoist Priest Encounter", and there is a sentence here "Lin Shen saw the deer", so he gave this word to his daughter's name. Lulu has a more introverted personality, every time she goes out to play, she is with Jiang Nianfeng, if Jiang Nianfeng is not there, she would rather not go out.

And once Jiang Nianfeng took Lulu out to play, and was called away by his mother for a while. On that day, Lulu was bullied by the senior children and ran home crying, Jiang Nianfeng secretly ran to fight with the senior children after he found out, trying to get justice for Lulu, but he was also beaten. Then, Jiang Nianfeng discussed with his parents that he wanted to practice sanda, saying that it was to strengthen his body, but when his parents heard it, they were very happy and let him go to school.

At the beginning, it was really hard to study, especially when I practiced basic skills, and I had to get up early on weekends, but Jiang Nianfeng gritted his teeth and persevered, thinking that when he finished practicing, he would find the senior "revenge". Thinking about it now, I was really innocent at that time, I just wanted to help my partner breathe, no matter how hard it was, I persevered, and it was thanks to that decision that I later won the Sanda National Championship.

After graduating from junior high school, Bai Jialu was sent by his parents to a private school, and the intersection between the two gradually decreased, and he only had the opportunity to meet during the New Year's holidays. In Jiang Nianfeng's eyes, this sister has never grown up. And the reason why I went to Bai Jialu was because Bai Jialu's brother was from the Criminal Investigation Department of the Zechuan City Public Security Bureau, and he was familiar with fingerprint collection and comparison, and Bai Jialu always stuck to her brother to teach her when she was a child, so she also learned some, and simple fingerprint collection can still be done.

This week, Bai Jialu's private school happened to be on vacation, so she went home. Finding Bai Jialu, Jiang Nianfeng directly expressed his intentions, and after listening, Bai Jialu said: "This is not difficult, but you have to get your squad leader's fingerprints first, otherwise there is no way to compare." ”

So, Jiang Nianfeng thought about where to get the squad leader's fingerprints, he couldn't press one on his hand, and he couldn't mix them with other people's fingerprints. Suddenly, his eyes lit up, and he said to Bai Jialu: "Yes, the squad leader has a cup, which seems to have been purchased by his relatives from overseas, and he never lets others touch it, and there should only be his fingerprints on it." ”

The two rushed to the school in a hurry, before the boss Yan gave Jiang Nianfeng a key to the classroom door, which came in handy, because they were going to go to the picnic the next day, most of everyone went back to change their clothes, plus the time was not early, and those who studied also brought back the books.

Walking to the class leader's desk, seeing that the cup was not taken away, the two saw that there was no one around, so they hurried to start collecting. I saw that Bai Jialu evenly sprinkled the black powder of the special material prepared in advance on the outer wall of the cup, and then shook it gently to let the excess powder fall, and the fingerprints were immediately revealed. Jiang Nianfeng couldn't help but praise loudly on the side: "Talent, talent." ”

"What are you stunned about, take a picture." Seeing Jiang Nianfeng happy next to him like a fool, Bai Jialu urged him to quickly take a picture of his fingerprints. After the photograph, the fingerprint powder was extracted again with white adhesive paper. After doing this, the two cleaned the surface of the cup and hurriedly left, although it was not a bad thing, but it was not easy to explain if someone else bumped into it.

The first step is to get the squad leader's fingerprints, and the second step is to prove that the counterfeit coins have the squad leader's fingerprints. In order to protect the integrity of the fingerprints, Jiang Nianfeng put the money in a transparent bag. Bai Jialu looked at these counterfeit coins and shook his head, Jiang Nianfeng saw this, and asked a little weakly: "What?" Can't extract this? ”

Bai Jialu frowned: "Not really, it's just that I don't have the ability anymore, I have to go to my brother, he happens to be on duty in the unit today, fortunately, the money looks relatively new, there shouldn't be many people's fingerprints." ”

The two of them didn't care about resting and went straight to the Public Security Bureau, and when they got to the door to register, they took three steps and two steps and ran to the Criminal Investigation Department, saw Bai Jialu's brother, and roughly told him what happened.

After a little understanding, my brother spoke: "It stands to reason that I shouldn't do these things, it's not custom-made, but let's make an exception today." Hearing that his brother was reluctant at first, Bai Jialu pursed his lips and was about to have a seizure, but as soon as his brother's words changed, Bai Jialu immediately hugged his brother's arm and said: "Brother is the best." ”

"Lulu, Xiaofeng, you two sit here first, and I'll go to the collection room." After confessing to the two of them, he took the bag of money into the collection room.

After about an hour, my brother came out with his things. Jiang Nianfeng asked anxiously, "Brother, how is it, can you collect it?" I saw my brother take off his white coat and put it aside and said, "Well, I got it, but there are many, and there are five of them more clearly, let's look at these five first." ”

"Wow, my brother is the best, how did you do it, teach me next time." Bai Jialu shook his brother's arm again and said. "You can't get this at home, you need some materials, in fact, it's not difficult, it's iodine fumigation, I told you before, I'll teach you next time." Seeing his sister's naughty and adoring appearance, my brother couldn't be happier.

Then, the elder brother transferred all the fingerprints of the head of the cup collected by Jiang Nianfeng and the five fingerprints just extracted to the computer for comparison, and when the comparison reached the fourth, the surprising result appeared, and the fingerprint similarity reached 98%. Seeing this result, Bai Jialu jumped up happily, and Jiang Nianfeng was also relieved, with such evidence, he was not afraid of the squad leader prevaricating and denying it.

The elder brother sorted out the two fingerprint patterns and the comparison results and handed them to Jiang Nianfeng, Jiang Nianfeng thanked him again and again, and then left with Bai Jialu. After coming out, Jiang Nianfeng took a hard breath, and Bai Jialu said jokingly after seeing it: "What's the matter, the gas is not enough?" Jiang Nianfeng said with emotion: "That's not it, I just feel a lot more relaxed in an instant, I didn't expect that the good and evil of people's hearts have to be pondered and experienced now, and it is really indispensable to guard against people." ”

"Then you have to be careful in the future and protect yourself, Xiao Fengfeng." Bai Jialu pretended to caress Jiang Nianfeng's back and said. "What about me, you little devil who doesn't dare to go out?" Jiang Nianfeng was not to be outdone, and also teased Bai Jialu. "You •••••• stop for me" Bai Jialu just raised his hand and was about to hit Jiang Nianfeng, Jiang Nianfeng ran away. On the brightly lit road, the two chased after each other, like when they were children.

Tired of running, both of them stopped out of breath, and when they recovered, they realized that they hadn't bothered to finish their meals all afternoon. So we went to the snack bar I used to go to to eat something, and ordered two of my favorite hot and sour noodles, which actually came from Baijialu. When I was a child, I didn't have much pocket money, and the two of them could only buy one thing, Jiang Nianfeng would accommodate Baijialu every time and order a hot and sour powder. And now, there is no need to accommodate, and Jiang Nianfeng has long been used to it.
