There was silence. Pen, fun, and www.biquge.info

Complete, suffocating silence.

Silent.

Walking in from the door, the entire second floor is a reading area for ordinary books, and a large space extends in all directions.

The floor is covered with the same light grey carpet as on the ground floor.

Teru Kazama and her assistant Eri Fukatsu walked in this reading area, and the silent building was not even audible in the footsteps.

And.

Even with sunlight streaming in through the windows, the large free reading area on the second floor is quite dim.

"It's really a great place to read a book. Kazama glanced around and found the low shelves of magazines and books, and searched for the computers for the collection - nothing was wrong.

On the opposite side are three rows of large wooden bookshelves.

The spine of a large number of books is directed in the direction of Kazama.

Although it is only a local library in Rice Flower Town, the appearance of three rows of bookshelves running smoothly into the depths is still very solemn.

There are longitudinal passages between the bookshelves and the bookshelves, and there are four passages including the left and right windows.

Kazama and his assistant make their way through the passage between the computer and the magazine rack.

After passing through the sides of the three bookshelves, they were greeted by a wide space of square stools arranged parallel to the bookshelves!

"Alright, let's get to work. Kazama's eyes were clear and focused, and he didn't glance at the assistant next to him.

"Yes!" replied Eri Fukatsu in a low voice.

From the investigation box, she handed the white gloves used for on-site forensics to her medical examiner.

Her hands were snow-white and warm, and in this yellowish light, they were as translucent as ghee, and if she were hungry, she would have been eager to bite on it.

Kazama doesn't look greedy.

The gloves handed by the other party were slowly put on both hands, and the ten fingers moved flexibly.

Follow.

Under the gaze of Eri Fukatsu, he fumbled for a bottle of yellow powdered agent in the investigation box she was carrying on one shoulder, which was the 'glowing ammonia' often used by forensic doctors.

Luminous ammonia, also known as luminol.

It is a yellow crystal or beige powder at room temperature, which is a relatively stable chemical reagent, and luminol is a strong acid, which has a certain stimulating effect on eyes, skin and respiratory tract.

Kazama stood on the wide place, spraying liquid on stools, carpets, and walls with a watering can!

Eri Fukatsu graduated from Saitama Medical University.

And since there is naturally no shortage of basic skills to be able to act as an assistant to the forensic doctor, she quickly recognized that this should be spraying luminol reagent, no wonder Forensic Kazama told her not to turn on the lights before coming here.

She obediently went to turn off the lights in the area.

Then she immediately returned to Kazama's side, staring at the place where the luminol reagent had been sprayed as if it had a great attraction, so that her eyes did not turn a glance, and her eyes were fixed on the spray!

Kazama gently sprayed everywhere where he smelled an unusual smell.

Then they slowly waited for the change, and the very curious young detective team sneaked in from behind.

"Sister. What is this?" Ayumi, a curious little girl, stood at the entrance of the passage and asked Eri Fukatsu with great interest.

Eri Fukatsu frowned slightly, her eyes moved away from the floor, still not smiling, her expression was as cold as ice, she glanced at Ayumi and slowly explained: "This is called Lumino." The purpose of this stuff is simple, even if the blood stains at the crime scene have been wiped or removed, the investigating medical examiner can still use luminol to locate them. ”

His eyes shifted to Kazama.

Eri Fukatsu's eyes didn't blink: "Actually, the forensic doctor sprayed luminol and an activator solution in the area to be investigated, and the iron in the blood immediately catalyzed the luminous reaction of luminol, causing it to produce a blue glow. The amount of catalyst used in this reaction is very small, so luminol can detect traces of blood. ”

Eri Fukatsu's mouth closed, and then continued, "The glow lasts for about 30 seconds, and you can see from a long-exposure photograph that its surroundings should not be too bright. ”

She spoke calmly, as usual, and her gaze was unwavering.

"Huh?" Harata and Ayumi were dumbfounded when they heard this, and they only felt that everything that Eri Fukatsu said was as difficult to understand as the Book of Heaven!

And Conan and Mitsuhiko listened to it with relish, saying that they had learned.

"Eri Fukatsu, you've learned the basics well. ”

Kazama smiled slightly, and looked at the assistant with an indifferent face gently, with recognition on his face.

Hearing the words-

Eri Fukatsu's expression remained the same, but the cold smile gradually changed its taste.

Her world suddenly became quiet, and what she read just now was actually memorized by her from the school!

But when Kazama told the Twilight Police Department just now that she would give him ten minutes to find clues, she was really shocked.

Because.

When she came, she didn't think of using this trick at all, and second, she couldn't be sure if the missing person really had an accident in this library, and third, she couldn't accurately find the place of the incident in such a short time!

From experience

Survey ideas

Ability to judge

She is inferior to Kazama in all aspects.

"Damn, I'm not a few years older than me, maybe younger than me. Eri Fukatsu glanced at the smiling man sitting opposite, still as calm and introverted as before, wanting to suck in the hearts and minds of those who saw it!

Her gaze flashed with a hint of complexity, and her bright pupils were like discolored amber, constantly changing colors.

Kazama just glanced at her and then looked away, so he didn't notice her changes, and even if he saw it, he would only laugh it off.

Keep your eyes on Ayumi and Motota.

Kazama's slight smile was tinged with a warm breath: "Actually, it's not complicated, the luminol reaction in criminal investigation, in layman's terms, is that as long as there is blood splashed and stained on any object at the scene of the murder, no matter how it is removed afterwards, as long as it is sprayed with luminol reagent and observed in a dark environment, the original bloodstained place will have a blue-white fluorescence due to the fluorescence reaction." ”

"Of course, hydrochloric acid can also be used, just because there are blood stains, and it is okay to react to them, but it will leave traces of the reaction. ”

"I see, Brother Kazama, I understand this time. Ayumi suddenly smiled.

"Well, I Yuan Tai also understands. Yuan Tai stood next to her and shouted.

"Hmm. Kazama smiled faintly and took out another UV lamp from the box.

This is a professional UV lamp.

The power is comparatively large.

It is specifically designed to detect fingerprints and footprints, and of course, it can also show a luminol reaction!

"It's amazing, Ayumi, Motota, look at it!" Mitsuhiko's voice of surprise clearly entered everyone's eardrums.
