Translator: Atlas Studios Editor: Atlas Studios
Yue Xin put down the first aid kit first and prepared to break in as the next step. She pressed her palms together facing the door and prepared to use the divine power in her memory. She was no longer an ordinary Yue Xin, but the Yue Xin who had learned how to pick locks in her memory!
Just as Yue Xin found a wire to show off her skills, she suddenly realized that the door of her house was locked with fingerprints. Boohoo…
Yue Xin, female, 12 years old. Perhaps everything went too smoothly. Her brain was a cheat. In the past, her life wish was that the boy she liked would like her too. Now, her wish was to open the door in front of her and obtain the weekend life she had dreamed of.
However, the memory in her head did not have any knowledge about unlocking the fingerprint lock. She only had knowledge about unlocking the iris lock and the 64-bit password lock. However, the fingerprint lock should be similar to the iris lock. As long as she could extract biological information, she could open it. Was the method of extracting the iris the same as the method of extracting fingerprints?
Yue Xin took out her phone and was about to search on Baidu when she was stunned. That’s right, she had forgotten that her phone was no longer the original phone. She had already lost Baidu…
She had to start from two days ago. That day, for some reason, Yue Xin searched on Baidu for why people had oral ulcers. The results of the search shocked Yue Xin. It was suggested that she might have cancer and that she should go to the hospital for a checkup.
She did not expect such a good thing to happen. She immediately ran to look for her brother and expressed her wish to spend the rest of her life in the hospital.
Big Brother listened to her seriously and asked her questions seriously. Then, her Baidu disappeared from her phone. Although she could download it back, she was certain that Big Brother would be unhappy.
Yue Xin had no choice but to open the class group chat. Although she always slept in school, she knew that her classmates were very powerful. Yesterday, she was bored and looked at the class group chat. She even saw someone in the class discussing whether the modus operandi of a mystery novel was feasible. Perhaps she could ask if someone knew how to extract fingerprints.
She opened the class group chat. At this moment, Yan Ye was competing with his classmate in solving the questions. Whoever could solve the same question with the most methods would win. Seeing the photos popping up in the group chat, it could be seen that this competition was very intense. Li Xiaoyu would occasionally post the real-time scores and make a fuss.
Yue Xin took a look and didn’t understand, so she left again. After waiting for a while, she entered the group to take a look. The pictures in the group had already stopped scrolling, so she typed a message and sent it.
[Excuse me, does anyone know how to extract fingerprints at home?]
After sending the message, she stared at the phone screen and waited for a
reply.
Very soon, Li Xiaoyu replied: [Why are you taking fingerprints at home? Did something happen? Do you need me to call the police for you?]
Yue Xin saw that Li Xiaoyu had misunderstood and quickly explained: [No, I want to enter Fourth Brother’s room, but he won’t open the door for me. I just want to know if I can open the fingerprint lock by extracting fingerprints.]
After she sent this message, the group was silent for a few seconds. Gao Yue was the first to send a message to break the silence. “Xin, we’re already junior high school students. You can’t peek at your brother.”
Yue Xin was speechless.
[He’s injured and crying in his room. My brother said something might happen to him if I were to leave him alone. He asked me to bandage his wound.]
Yue Xin didn’t say anything about the deal. It wouldn’t work if she said anything about the deal.
Her words seemed to have turned on some strange switch. The people in the group suddenly became excited. People who usually didn’t talk jumped out and sent messages one after another. They were all about fingerprint extraction.
Yue Xin looked at them carefully.
[Fingerprint extraction is only applicable to smooth and holeless objects such as glass, window frames, switches, and so on. The first step is to gently sweep the dust off the fingerprints on the surface of the object with a thin and soft fluffy brush. This dust is stuck in the gap of the fingerprint. After removing it, you press the fingerprint with clean sticky tape. Then, you pick up the tape and press it on the clean paper. The fingerprint is then extracted onto the paper.]
Yue Xin nodded, indicating that she had remembered. She began to read the next message.
[Find a piece of bill that your brother has held, or any paper that he has touched. Spray it with ninhydrin and iron the paper with a heated iron. Wait for a moment, and the fingerprints will show.]
Yue Xin simply looked at the next line. Where could she find ninhydrin?
[Try it with iodine steam.]
[How about getting a police officer to buy a laser gun that can detect fingerprints?]
[If you can find the police, why don’t you just find a fireman to break the door?]
When Yue Xin saw this sentence, she suddenly had an idea. Why did she have to spend her brain cells to extract fingerprints? The butler had just said that other than him, only Eldest Brother could open Fourth Brother’s room. In other words… it was better to call the police. She was just an underage child.. What could she do?
