"If you ask me this question, who can I ask?" Even at this time, Shimamoto Hikonari did not give up, and argued: "If you insist that I answer, I can only guess that this gelatinous substance may have been left on this tall glass wine glass!" ”

Lin Jiangbei picked the gelatinous substance off the wine glass with the tip of a needle, and showed the silver sub-rain rice new desert powder particles adhered to the other end of the gelatinous substance to Shimamoto Hikonaru.

"Hikonari Shimamoto, if this gelatinous substance was originally left on this tall glass, then how do you explain that the other end of it also has sub-rain rice powder particles sticking to it? Could it be that when you show your fingerprints, you will first pick up this gelatinous object and spray it with sub-rain rice new desert powder particles and then stick it to the wine glass again, and then use a duster to spray sub-rainy rice new desert powder to make the fingerprints visible? Lin Jiangbei said with a sneer.

"That may be the fact that the manufacturing plant of Yayu Mi New Desert Powder accidentally mixed in the gelatinous substance during production, how do I know what is going on!" Shimamoto Hikonari can only pretend to be a scoundrel.

He didn't expect that as a personal disciple of Japan's first criminal investigation master, Nanba Saburo, he would one day be forced into such a situation by a Chinese criminal investigator in a place like Shanghai.

Lin Jiangbei was also angry and happy by Shimamoto Hiko.

Similarly, he didn't expect that Shimamoto Hikosei, the senior detective of the patrol room of the Ministry of Industry Bureau and the senior disciple of the Japanese criminal investigation master Minami Saburo Minami, faced with the moment the forged evidence was exposed, his reaction was no different from that of the thugs who were lying on the ground and rolling on the streets of Shanghai, and they were able to play a scoundrel regardless of their face.

This kind of goods is destined to be born in Japan, if it is really born in Shanghai, it is estimated that it will be one of the most unpopular gangsters on the street!

"Hehe, how do you know?" Lin Jiangbei chuckled, his face suddenly became stern, "How could you not know?" ”

He shook the gelatinous particles on the tip of the millineedle with his hand, and continued: "Shimamoto Hikosei, you just admitted that you are a personal disciple of the Japanese criminal investigation master and head of the Security Division of the Police Security Bureau of the Ministry of Internal Affairs, Nanba Saburo, and you have studied with him for three years. So the original Nanshi paper fingerprint extraction method created by Saburo Nanba will not be taught to you, right? ”

"What is Nan's Adhesive Fingerprint Extraction? I didn't know! Shimamoto Hikoto's premonition saw that the "Jackson Ren" in front of him even knew about the Nan's adhesive paper fingerprint extraction method created by his teacher, Saburo Minami, and he understood that it would be difficult for him to get through the test today.

His only hope now is that this Mr. "Jackson Ren" only knows that his teacher, Saburo Minamiba, has created the Nanshi adhesive paper fingerprint extraction method, but he does not know the details of the process of how to make the adhesive tape.

Because of Mr. Nanbazaburo's original Nanshi adhesive paper fingerprint extraction method, the key secret is how to make adhesive paper that can extract fingerprints that remain on the surface of the body. This core process is the real secret of Saburo Minamibaza.

Shimamoto believes that as a Chinese-American criminal investigation expert, even if there are channels to learn that Nanba Saburo created the Nanshi adhesive paper fingerprint extraction method, it is absolutely impossible to know the core adhesive paper production technology process of Nanba Saburo Nan's adhesive paper fingerprint extraction method!

As long as you don't know how the adhesive tape is made, then it is impossible to come up with physical evidence that you used adhesive tape in the previous forgery of evidence. Without physical evidence, no matter how arrogant the Americans are, they would not dare to convict a Japanese senior detective lightly on the territory of East Asia!

"Hehe, you don't know the Nan's paper fingerprint extraction method at all?" Lin Jiangbei smiled lightly again, and looked at Shimamoto Hikonari playfully, "Do you think that as a personal disciple of Nanba Saburo, you don't know that Nanba Saburo's original Nanshi Adhesive Paper Fingerprint Extraction Method will be believed?" ”

"Whether you believe it or not, anyway, I just don't know what Nan's paper fingerprint extraction method is!" Hikonari Shimamoto said with his neck straight.

Seeing that Lin Jiangbei had been arguing with Shimamoto about this Nanshi plastic paper fingerprint extraction method, Colonel Price couldn't hold back his curiosity and asked Lin Jiangbei: "Mr. Ren, what exactly is the Nan's plastic paper fingerprint extraction method?" ”

"Colonel Price," Lin Jiangbei explained to Colonel Price, "After the fingerprints on the surface of the object are displayed, the fingerprints must be extracted so that they can be preserved as evidence." ”

"The earliest fingerprint extraction technology is photographic extraction, that is, the fingerprints on the surface of objects are photographed and preserved. For example, in the case of Leonovsky's poisoning, Leonovsky's four fingerprints, as well as Major West's Bryan's forged fingerprints, all use this photographic extraction technology to preserve fingerprints. ”

"Actually, in 1928, Mr. Richard Drew of St. Paul, Minnesota, USA, invented scotch tape. Then people in the criminal investigation community began to try to use this kind of scotch tape, also known as adhesive tape, to extract fingerprints on the surface of the product. ”

"So in addition to the photographic fingerprint extraction technology, there is another technology for extracting fingerprints attached to adhesive tape."

"It's just that because this adhesive tape is relatively poor and is easily affected by air humidity, it can usually only be used in dry air environments. If it is used in a place with a humid climate or humid air, the fingerprints will soon be blurred and lose the significance of evidence. ”

"This makes it impossible for countries with humid oceanic climates like Japan, as well as humid climates like Shanghai, to use this convenient adhesive paper fingerprint extraction method to preserve the fingerprints of crime scenes."

As the first person in Japan's criminal investigation circle, Saburo Minamiba was very dissatisfied with this situation, and was determined to develop a glue paper fingerprint extraction technology that adapts to Japan's humid maritime climate. Finally, in 1931, a special adhesive paper was developed that could clearly extract fingerprints under humid air conditions and could be stored for a long time. ”

"In order to distinguish it from the technology of extracting fingerprints with adhesive paper invented by Mr. Richard Drew, within the Japanese criminal investigation circles, the technology of extracting fingerprints from this special adhesive paper invented by Saburo Nanba became the fingerprint extraction method of Nan's adhesive paper."

Seeing Lin Jiangbei talking eloquently to Colonel Price, Shimamoto Hikosei was shocked and frightened in his heart. He really didn't expect that Lin Jiangbei not only knew about the Nan's paper fingerprint extraction method, but also knew so much about the characteristics of the Nan's paper fingerprint extraction method.

He had a not-so-good feeling in his mind. Since this Mr. "Jackson Ren" understands the characteristics of Nan's fingerprint extraction method so well, is it possible for him to understand the original special adhesive tape manufacturing technology created by Mr. Nanba Saburo?

Lin Jiangbei glanced at Shimamoto Hikosei's face, smiled coldly, and continued to say to Colonel Price: "Of course, compared to the adhesive tape invented by Mr. Richard Drew. The manufacturing method of this special adhesive paper is more complicated and cumbersome. ”

Speaking of this, he turned his head to look at Shimamoto Hikosei and said: "Shimamoto Hikosei, I will now tell you about the specific process of Mr. Nanba Saburo's special adhesive tape manufacturing, and if there is anything wrong in the middle, please also ask you, Mr. Nanba Saburo's personal disciple, to help me check and see if what I said is right!" ”

Hikonari Shimamoto gritted his teeth and said nothing. In his heart, he was praying frantically, "Jackson Ren" was deceiving him, and it was impossible to really master the special adhesive tape manufacturing technology of Mr. Saburo Nanbazai.

"In order to make this special adhesive tape invented by Mr. Saburo Minamibaza, the following items are first needed." Lin Jiangbei looked at Shimamoto Hikosei and said unhurriedly: "There are one and a half pieces of animal glue that are nine inches long and three inches wide, 8CC of distilled water, 6CC of glycerin, and 0.5 CC of acetic acid. Mr. Hikonari Shimamoto, I wonder if there is anything missing from what I said? ”

How is this possible!

Hikonari Shimamoto was struck by lightning.

Although he had guessed in his heart that this Mr. "Jackson Ren" might really know about the special adhesive tape manufacturing technology invented by Mr. Saburo Minamiba, but at this time, he heard "Jackson Ren" say that the items needed to make special adhesive tape were just as bad, and he still couldn't hide the shock in his heart.

"Hehe, Shimamoto Hikosei, although you didn't answer my words, but looking at your face, I also know that what I just said is exactly what I said in terms of the type and weight of the items."

Lin Jiangbei smiled faintly, ignored Shimamoto Hiko's reaction, and continued: "The utensils needed to make special adhesive tape are a beaker, an enamel cup, an alcohol lamp, a tripod and a pair of wire yarn, a measuring cup, a glass rod, a few waste photo negatives, and several pieces of glass. ”

"The manufacturing steps are to first soak the animal glue in water to make it soft, put the waste negative on the glass, surrounded by glass strips, put the animal glue and distilled water in the beaker, and put the beaker in the enamel cup with water, then boil and mix thoroughly, inject glycerin after 40 minutes, add acetic acid after 10 minutes, and then 5 minutes, then mix, dump on the waste negative, cool every 24 hours, and cover it with a layer of film, that is, it becomes a transparent special adhesive tape."

"When taking fingerprints with this special adhesive tape, the sticky side falls on the fingerprint of the powder, lifts it with smooth and average force, so that all the fingerprints are left on the adhesive tape, and then gently lifts it, and the fingerprints will be very clearly printed on the special adhesive tape."

"The fingerprints are so clear that they can even be transferred from the special tape to another item again. This is also where Nan's specialty adhesive tape is more powerful than the transparent adhesive paper invented by Richard Drew! ”

When Lin Jiangbei said this, he walked up to Shimamoto Hikocheng again, stretched out his hand and gently lifted Shimamoto Hikocheng's chin, and looked at him with a smile: "If I guessed correctly, you should have obtained the item with West Bryan's fingerprints from other sources, and then used the special adhesive paper such as Minami Saburo to extract the fingerprints of West Bryan on it, find out the clearest one of them, and then print it on the top of the tall glass wine glass containing poisoned wine, so as to create the West · Evidence that Major Brian poisoned Leonofsky! That's why Major West Bryan's fingerprints have gelatinous particles on them. ”

"If it weren't for the fact that I happened to know Nanba Saburo's Nan's adhesive paper fingerprint extraction method, and I also knew Nanba Saburo's specific special adhesive paper manufacturing technology, maybe I would have been fooled by you this time!"
