The thin and tall director of Ochiai breathed a sigh of relief, lowered his head, as if there was no more moral pressure on his shoulders, and asked, "Where are the loopholes?" ”

As soon as this remark came out, it was directly equivalent to the admission of Director Ochiai, most of the museum staff were surprised, even Xiaolan was a little incredulous, it was hard to imagine that the curator who was interested in introducing the artworks of the museum in the afternoon would commit a criminal act.

Chen Jun pointed to the scarlet blood stains on the wall, "Right there, that is a very unusual point, because the artwork and paintings that were originally under those labels are all gone, leaving only blood."

It would be reasonable to say that someone had emptied all the artworks and paintings in the exhibition hall, but why not remove the "Heavenly Punishment" as well? ”

This can only indicate that the murderer is likely to be a person who loves paintings and cannot bear to defile them. ”

Director Ochiai raised his head, a smile appeared on the corner of his mouth, and his eyes were full of love and yearning, "I love those paintings, they are like my children, of course they can't be defiled." ”

"Whoever defiles me, I will fight with whomever I want!" He changed his words and showed fierce eyes, but immediately lowered his eyebrows, "What else?" ”

"There's one more piece of critical information."

Chen Jun closed his eyes slightly and thought about it, feeling the changes around him, and after a few seconds, he opened his eyes and asked, "A person like you, Director Ochiai, who regards art as a treasure, should have done a good job in protecting artworks, and today I also saw you teach Kuwata who is not wearing gloves a lesson." ”

Such an inconsequential and incomprehensible question puzzled many police officers, but Xue Sui showed a slight smile on the side.

Director Ochiai said with pride, "Of course, in Tokyo, I believe that there are few people who can do as well as Ochiai in terms of the means of protecting artworks." ”

"This is very consistent, before entering this exhibition hall, I had a slight feeling that the temperature of the exhibition hall has risen compared to the outside world, and the air is relatively dry, if I guess correctly, these are the conditions for the protection of artworks."

Director Ochiai nodded: "Yes, in order to protect those "delicate" artworks, the exhibition hall has been professionally controlled and adjusted, not too high nor too low, the temperature is kept at 18'C to 24'C all year round, and the relative humidity is below 40%. ”

"Since the temperature control and humidity adjustment have been done, Director Ochiai must have taken care of the artwork more carefully." Chen Jun smiled lightly and looked at Xue Sui beside Xiaolan, "I don't know much about art conservation, but my girlfriend Xue Sui knows these things very well." I would like to ask, how to maintain calligraphy and painting, and how to maintain armor in the face of bronze and ironware? ”

Xue Sui glanced at him, "The maintenance of calligraphy and painting should avoid sunlight, ultraviolet radiation, reduce photography, reduce cold light, and the surface of calligraphy and painting should be treated with insect and mildew prevention, and it is best to place it in a special closed display case." ”

"Bronze and iron, like armor."

Xue Sui looked at the bloody armor on the physical evidence, "Not so valuable, it must be kept dry in the air, dust and rust must be removed, it needs to be cleaned with a pubescent cloth and a soft brush, and the surface maintenance needs to be coated with a layer of melted natural paraffin, or coated with a layer of silicone to prevent harmful gases and moisture corrosion." ”

"Natural paraffin wax or silicone!"

Chen Jun snapped his fingers, "I'm sure Director Ochiai used one of them. ”

Director Ochiai said, "Natural paraffin! ”

Chen Jun said calmly: "That's right, the light gray suit of the director of Ochiai is made of polyester, which is polyester fiber, hydrophilic, and easy to absorb moisture. According to the time of the crime at 4:30 and now at 6:15, you haven't had time to change your clothes, and now the surface of your suit is already stained with natural paraffin wax when you wear the armor. ”

"The Metropolitan Police Department of Japan should not be equipped with trace substance detection equipment, but the laboratories of Tokyo University and related medical universities will have scanning electron microscopes, X-ray energy spectrometers, and Fourier (microscopic) infrared spectrometers for the detection and comparison of criminal components.

"Very scientific verification method, forensic medicine is great, I hope you, the corpse whisperer, can get justice for more wrongful deaths in the future."

The old man smiled and shook his head again, "But this person is not worth it at all, this wolf-hearted demon, for his own selfish interests, he wants to destroy the sacred art museum, it is unforgivable, I know that my behavior is also stupid, just like the painting "Heavenly Punishment", although the righteous knight stabbed the demon to death, he himself suffered the baptism of demon blood, which means that he was also violated by the devil, and he became a demon..."

Soon after, Director Ochiai was taken away by the police.

Chen Jun took off his milky white medical gloves, and immediately the scene burst into amazing applause, dedicated to the corpse whisperer, and saluted with breathtaking eyes.

After a long break, Officer Twilight came over on behalf of the police to thank him and asked a question:

"Now it seems that all this is too deliberate and too coincidental, it seems to be completely like a performance under the monitor, inducing and pushing us step by step, especially the name in that note, the paper has signs of wear, like scratches from the tip of a pen that cannot be written, but when we search for physical evidence that is a ballpoint pen that can write in good handwriting, what is going on?"

Xue Sui jumped and ran over, put her arm around Chen Jun, and said happily for Chen Jun, "It's not impossible to achieve such an effect. ”

"For example, at the right time, when no one is paying attention, use the bag meter, and the pen in the deceased's hand that cannot write should still be on the curator."

A few steps away, Conan held back the words on his lips.

This experience is still the first time he has "enjoyed"

"Big brother Ito, is the forensic really a corpse whisperer?" He still couldn't help but ask.

"What do you say?"

"There is a very famous Chinese forensic scientist in the United States, and I admire him, his name is Li Changyu, who completed four years of university courses in two and a half years: law, criminal, biology, and chemistry. He received his M.S. in Biochemistry and Molecular Chemistry and Ph.D. in Biochemistry from New York University.

He is also one of the most well-known police elites in the United States, and has participated in the investigation of more than 6,000 major criminal cases in various states in the United States and 17 countries around the world, presiding over more than 300 cases on average every year. Including several classic cases: the rape and murder of a 13-year-old girl, the murder of his wife by the director of public security, the case of the destruction of the body by a wood chipper, the murder of his wife by Simpson, etc. ”

"Corpses can speak, but they must be based on scientific evidence and professional testing instruments, and forensic doctors must have extraordinary courage, experience and logical judgment ability.

Forensic science is a discipline, a science, and a system, but today and many countries around the world are limited by knowledge, thinking, technical ability, and talent reserves, so there is room for detectives to survive, hahaha..."

Conan: "....."

Seeing the two of them leaving, how did he feel as if his identity had been seen through.
