Shen Yue, female, 12 years old, has a smooth life (probably), her head is open and open, her previous wish in life is that she hopes that the person she likes can also like herself, and now her wish is to open this door with a fingerprint lock to usher in a comfortable and comfortable weekend.

But she doesn't have the knowledge to open the fingerprint lock in her head at the moment.

She only knows how to open the iris lock and the 64-bit combination lock.

However, the fingerprint lock should be similar to the iris lock, as long as the biological data can be extracted, the lock can be opened.

Is the method of iris extraction the same as that of fingerprinting?

Shen Yue took out her mobile phone and was about to B degree, when she was suddenly stunned, yes, she forgot, her mobile phone was no longer the same mobile phone at the beginning.

She...... B degree has been lost.

Things have to start from two days ago, that day Shen Yue didn't know why she had an ulcer, so she took out her mobile phone B Why did people grow ulcers.

The answer given by degree B is: Thank you, you may have cancer, and it is recommended to go to the hospital for examination.

Shen Yue was shocked, he didn't expect such a good thing, so he quickly found his eldest brother and expressed his desire to go to the hospital for the rest of his life.

Under the eldest brother's seriousness, black lines on his face, and some inquiry, her B degree left her mobile phone forever.

Although she can still bring back the B degree, the eldest brother will be unhappy.

So Shen Yue gave up asking about B degree, and instead opened her class group.

Although she always let herself go at school, she also clearly understood that her classmates were amazing.

When I peeked at the group yesterday, I also saw a classmate discussing the feasibility of the crime method in the criminal investigation novel, maybe she could ask how to collect fingerprints.

Shen Yue opened the class group with the group name "Cute Love, Three Heads", at this time, Ye Yin was competing with other classmates in the group to find out who could solve the same problem in more ways, and the small photos jumped out one by one, and it could be seen that these people were very fierce.

And Qing Xiaoyu sent a message from time to time to record the scores in real time for the two of them, and by the way, they coaxed.

Shen Yue clicked on it and glanced at it, saying that he couldn't understand it, and retreated again.

Thinking early in the morning, she is worthy of being a person with three heads, she is different, she has only one, so she doesn't think.

Shen Yue looked at the screen and didn't start typing until the picture stopped swiping.

[Excuse me, how can I collect fingerprints at home?] 】

Shen Yue sent out a message and began to stare at the screen waiting for a reply.

Soon, Qing Xiaoyu was the first to reply to her.

Why do you need fingerprints at home? Is something happening? Do I need to call 110 for you? 】

Shen Yue saw that Qing Xiaoyu had misunderstood, so he hurriedly explained.

[I want to enter my fourth brother's room, but his room is locked, and I wonder if I can unlock it by taking fingerprints.] 】

After Shen Yue said this, the group was silent for a while, and Gao Qin broke the peace.

【Yue'...... We're already mature first-year junior high school students, so it's a shame to peek at my brother. 】

Shen Yue: ?

[He was crying, and my eldest brother said that no matter what might happen to him, he wanted me to bandage his wounds. 】

Shen Yue didn't say anything about his deal with his eldest brother.

Trading this kind of thing, it doesn't work to say it.

And Shen Yue's words, I don't know what switch was turned on, and everyone in the group suddenly became excited.

One after another, people who usually diver began to pop up, and one message after another continued, and a closer look was actually all about how to extract fingerprints.

Shen Yue looked over one by one.

[There is a method for extracting fingerprints from smooth and non-porous surfaces such as glasses, window frames, and switches.] First of all, use a soft fluffy brush to gently brush off the fingerprint dust on the smooth surface of the object, these dust were originally stuck in the fine slits of the fingerprints by sweat, after removing them, the hidden fingerprints are exposed, and then press the clean adhesive tape on the fingerprints, and then pick up the tape and press it on a piece of paper, and the fingerprints will remain on the paper. 】

Shen Yue remembered it and continued to read the next one.

[Find a piece of money that your brother has taken, or other pieces of paper that he has touched, spray ninhydrin on it, and then iron the paper with a heated iron, wait for a while, and the fingerprints will come out. 】

Shen Yue crossed it directly, what ninhydrin, she didn't have.

[Try it with iodine vapor.] 】

[How about going to the police uncle and buying a laser gun that can take fingerprints?] 】

[Since you can find a police uncle, why don't you just call 119? ] 】

When Shen Yue saw this, something crossed his mind and suddenly realized.

That's right, why did she waste so much effort to extract fingerprints, if it was really like the eldest brother said that the fourth brother was very dangerous in the room alone, and when she studied the fingerprints, the fourth brother would be cold.

That doesn't seem to work.

And she asked the housekeeper just now, and only the eldest brother can open the fourth brother's room, that is to say......

Call the police.

It makes sense.

She's just a little kid, what can she do!

Shen Yue gradually lost herself in the self-hypnosis of the children, and decisively took out her mobile phone to call the police.

Just when she was clearly articulate and her mind clearly described the dangerous situation that the fourth brother might encounter in the room to the other side of the phone, a housekeeper passed by Shen Yue and immediately ran over to stop her when she heard the call.

After apologizing three hundred times, I managed to hang up the phone.

The housekeeper touched the non-existent sweat on his head, and taught Shen Yue in a serious manner, "Little Miss, you can't call the police casually, and the security resources need to be reserved for those who are really in need." False police reports are punishable. ”

Shen Yue nodded, took back his mobile phone from the housekeeper's hand, pointed to Shen Jize's room and said, "But the eldest brother said that the fourth brother is injured, and he will be in danger regardless of his words." ”

"Hurt?" When the housekeeper heard this, he suddenly became nervous, and hurriedly called the bodyguard at the door to call in, and he didn't know where to find the tools, and began to attack the door of Shen Jize's room with the most primitive method, and finally succeeded in opening it.

And almost at the same time as the door was opened, the atmosphere became tense.

Shen Yue leaned over to look and saw Shen Jize sitting on the bed, and his bed had been dyed a lot red, even if he looked at it from a distance, he felt shocked.

Seeing the door suddenly opened, Shen Jize was startled and shouted at the door, "Don't come here!" Don't come! ”

The housekeeper was very helpless, but it didn't seem to be the first time he had seen this kind of scene, so he could only slow down his voice and persuade, "Si Shao, you are injured and need to be bandaged." ”

"You go, leave me alone."

"Four Young ......"

"You go, woo woo woo." I cried again.

Shen Yue watched in amazement, but after thinking about it, it seemed that he could understand this feeling.

It's weird, I don't want to think about it, let's complete the task first.

So Shen Yue ignored Shen Jize's whining and resistance, walked directly to his bedside, lifted the quilt, found the wound, and began to disinfect.

Shen Jize looked frightened when he saw Shen Yue approaching him, but the more he got to this time, he was even more speechless, and he could only keep shedding tears, looking so pitiful.

For the first time today, Shen Yue experienced what it was like to have an incessant whining sound.

Moreover, in the process of bandaging, Shen Yue also discovered that Shen Jize's body seemed to be different from ordinary people, obviously it was just an ordinary wound, but the amount of bleeding was far greater than that of ordinary people.

Coagulation abnormalities.

No wonder the eldest brother asked her to come in and take a look, otherwise it would really be cold.

After finding the medicine to stop bleeding from the bottom of the first aid kit and applying it to Shen Jize, Shen Yue put an oversized band-aid on Shen Jize's wound.

Let's live!

Shen Yue appreciated the success of his labor, took a photo, and sent it to his eldest brother, indicating that he had completed the task, and then decisively threw away the first aid kit on the spot, left in style, returned to the bed, and slowly lay down.

Shen Jize stared blankly at the back of Shen Yue simply leaving, and froze.

Is she just gone?

Don't ask anything?

She was crying all the time, and she wasn't curious?

And why do you want to help yourself bandage your wounds?

Shen Jize had a lot of things to ask, but he didn't ask a word.

He was afraid.

The housekeeper stood at the door without speaking, and when he saw Shen Yue leaving, Shen Jize also stopped his tears before he spoke, "Si Shao, the first aid kit is under your bed, and now the little lady has sent another one, next time you must bandage the wound in time." ”

Shen Jize looked at the first aid kit that Shen Yue left in place, looked at his wound again, and suddenly pressed his hand heavily on the wound.

It hurts.

It turned out not to be a dream.

In addition to the eldest brother, will there be other people who care if he is not injured or not?

Shen Jize couldn't be sure, and he didn't dare to be sure.

At this time, Shen Yue was already lying on the bed, reporting the results of fingerprint collection to her cute classmates with three heads.

[I didn't take my fingerprints, and I smashed the door directly.] 】

Soon, the group discussed it again because of this sentence, and finally came to a conclusion.

[The optimal solution is often the most simple way, such as why should I write the process if I can do mental arithmetic?] 】

[Upstairs is right.] 】

【+1】

【+2】

【+10086】

[So I only wrote the answer to my math homework, why did Mr. Niu say me? 】

[How do I know, he also said me.] 】
