Li Yanling was not afraid, and said solemnly: "You don't have this ability, but workers' security does. Any of us will leave fingerprints on that thing when we take it. We just need to use scientific and technological means to remove the fingerprints on these things. Fingerprints, you can know who this thing is."
People in this era still have the concept of fingerprint technology. But she came from a later life, so she is familiar with this thing. At that time, ordinary people knew what was going on even if they hadn't used any fingerprint technology.
However, people in this era are different, because fingerprint technology has not yet been popularized at this time. We usually don't have the chance to know each other at all, and of course we don't know. Fortunately, however, fingerprint technology has begun to develop. She remembered that this technology already existed in the late 1950s.
In the 1970s, fingerprint technology had already played a certain role in solving crimes. It's just more difficult, and there are certain technical difficulties, which are not used much. But fortunately, this technology already exists and has been used.
But the people around me don't understand, what I heard is very fresh¡ª¡ª
"What? Fingerprints? The fingerprints on our fingers can still stay on those things? Why didn't I see it!"
"She must be lying, why didn't I see any fingerprints on the yellow paper!"
"That's because you are uneducated!" Li Yanling despised those two people without hesitation. "Fingerprint technology has been developed more than ten years ago, and now some cases are investigated using fingerprint technology. As far as I know, indenazine Ketones, a chemical, can be used for fingerprinting at crime scenes."
Those two people were scolded for being uneducated, and they almost scolded others. They both graduated from high school, so why are they uneducated? But when they heard Li Yanling's profound words, they had a feeling that they couldn't understand, but they felt very powerful!
Don't talk about them, the group of people around are also confused, but everyone saw that what Li Yanling said was straight and honest, and it didn't seem like a lie. Everyone became curious for a while.
"Oh, is there really such a thing? Can our fingerprints really detect it?"
"I don't think she is lying, and if you don't look, she is not afraid at all. I think this thing may not belong to them!"
Zhu Qingjun was also confused, but the more he listened, the more frightened he became!
Because he doesn't think Li Yanling is lying, this woman is very wicked. Is there really any fingerprint technology? Can his fingerprints really be found out?
Thinking of how many times he had grabbed those two pieces of paper, he panicked.
The more flustered he was, the less he wanted Li Yanling to check her fingerprints: "Don't listen to her nonsense, arrest her!"
"She's not talking nonsense!" Cao Jingxiu's gentle voice sounded at this time.
His voice is very special, gentle and pleasant, and he stands out from the crowd. Everyone turned their heads to look at Cao Jingxiu.
Cao Jingxiu looked at Li Yanling in surprise. When Li Yanling mentioned the fingerprint technology just now, he was already very surprised. He didn't expect Li Yanling to know this.
He knew about fingerprint technology, and he learned about it by chance. But he didn't expect Li Yanling to understand! And Li Yanling knew more than he did. She also knew what ninhydrin was.
