"Not yet. We found a strange stone and asked the angel to bring it back for testing. We will go over to open the lock box later!" Zhuo Yifan nodded and explained.
"Stop chatting now, let's go to the laboratory!" Angel pulled Zhuo Yifan up anxiously and ran to the laboratory on the third floor.
After arriving at the laboratory, Zhuo Yifan handed the stone to the angel and watched her throw the stone on a test bench and started working in a cabinet nearby. After a long time, she found
What comes out is something like a card swipe machine. It just has an extra slender probe for fingerprint scanning. This kind of tool is used in on-site fingerprint extraction in criminal cases.
"This is a fingerprint scanner. As long as the other person's fingerprints are left on those buttons, it will definitely be scanned! As long as they haven't wiped the surface of the buttons after pressing them!" Angel explained.
"Then let's go there quickly!" Zhuo Yifan nodded and said.
Zhuo Yifan immediately took Angel and prepared to leave. As soon as he arrived downstairs, he was stopped by Fenghuang and Ziteng.
"We two have nothing to do, why don't we come with you to have a look, maybe we can be of some help!" Fenghuang took the initiative to make suggestions before Zhuo Yifan could ask.
Zhuo Yifan pondered for a while, then nodded in agreement. Then he drove the three girls back to the basement.
"You are all here?" Xie Dongting looked a little surprised when Fenghuang and Ziteng followed Zhuo Yifan.
"They happened to have nothing to do, so I brought them here. Maybe they can help!" Zhuo Yifan explained casually, and then asked: "After we left, nothing happened, right?"
"No. I'm the only one here, and I didn't find anyone else approaching!" Xie Dongting nodded and said.
"Let me see if there are fingerprints on those four buttons first!" Angel took the fingerprint scanner and went directly to the safe, cleaned out all the bottles and cans inside, and then used the scanner to
I scanned the buttons separately.
"Yes!" the angel suddenly shouted excitedly.
"Have you found the button?" Zhuo Yifan asked energetically.
"That's right, it's just like what you said, only one button has traces of being pressed!" Angel nodded and replied.
"Then what are you waiting for? Open it quickly and take a look!" Zhuo Yifan said with joy on his face.
"Wait..." Xie Dongting suddenly shouted.
"What's wrong?" Zhuo Yifan couldn't help but frowned when he heard this.
"What if this is also a trap set by the Long family? They rely on fingerprints to find the button. I guess the other party can figure it out. They didn't deliberately leave such a loophole for us and let us press the wrong button, right?" Xie Dongting
asked hesitantly.
"I know what you are worried about. What I said is that there is only one button with traces of pressing, not fingerprints!" Angel explained with some dissatisfaction.
"What do you mean?" Xie Dongting asked in confusion.
"Fingerprints have been left on these four buttons. Obviously, the other party has also thought about fingerprint recognition, so each button has fingerprints of different people. This is easy to do, and there is no need to press
Just go down and touch it with your fingers." Angel explained, pointing to the four buttons and continued: "But they overlooked one thing. Some of the chemicals placed outside the safe are volatile.
There is a thin layer of grease accumulated on these buttons, which is difficult for ordinary people to detect. I only saw the clues when I looked at these fingerprints. There is only one button, and the protruding parts around it are relatively clean, which is better than the other three.
The grease on each one should be thinner. It is obvious that part of it was scraped off during the process of pressing and popping up."
