Qin Bangcheng, the chief of the investigation section, is an extremely experienced criminal investigation seller, in this special era, he does not know how much about guns and explosives, and he is very familiar with firearms and the underground black market in Shanghai, and he reports on the investigation of explosives and firearms.

"Director, let's talk about explosive......s first" Qin Bangcheng is 42 years old, he used to be a detective for 12 years and solved countless cases, but he was not promoted, it was Li Junhao who took control of the police department, transferred him to the reorganized investigation department, and promoted him to the chief of the detective section, he admired and was convinced by this young boss, plus the role of the red bottle, extremely loyal! This time Li Junhao was assassinated, and his heart was full of anger, and he vowed to find out the black hand behind the scenes.

"Minister Wang's previous judgment was very right, the explosives in the drainage well are TNT, commonly known as yellow explosives, this kind of explosives are mainly used by the military of various countries, and it is difficult for ordinary people to come into contact with ......," Qin Bang said, "Therefore, TNT is rarely seen in the market, and there are few black market sellers, and they have a tacit understanding with each other, and they will not sell TNT to people they don't know, because once something happens, the consequences will be very serious......

"I've personally inquired and no one has sold TNT on the black market for the past three months, and although it's not 100% certain, it's more likely that they bought it three months ago, or they have other sources of TNT, and I'm leaning towards the latter.

"The firearm used by the killers was a modified German-made MP18, with the wooden butt cut off and only the grip remaining, which reduced the length and volume, but was very demanding for the user......

"Just now after listening to the results of Section Chief Green's investigation, I have an idea that these five Chinese should also have military experience, because it is difficult for ordinary people to come into contact with MP18 weapons."

Hearing this, Li Junhao and the others all nodded in approval.

Qin Bangcheng continued: "I checked these 12 MP18s, all of which are imported from the original German factory, although they are only seventy percent new, but they are well maintained...... Considering that this is already a relatively old firearm, the number of such original goods existing in China will not be too much, I judge that these guns are the weapons used by the national army during the last Shanghai Sea War, and they were collected by people with a heart and kept until now. ”

His statement made everyone's eyes shine, in this way, there is a goal to point to - the national army was defeated and withdrew from Shanghai, and there was not even a chance to clean up the battlefield, this force that can take out 12 original MP18 at a time is about to come out: the Japanese army!

Although it is said that gang forces such as the Green Gang also have this possibility, considering the style of these gangs, it is impossible to endure the old guns that were obtained two years ago, let alone maintain them so well.

At this time, Zheng Pingru asked: "Section Chief Qin, is it possible that the killer bought this batch of guns on the black market?" ”

Several others had the same question, and nodded in agreement.

Qin Bangcheng knew her, and replied politely but resolutely: "Secretary Zheng, this possibility is extremely small, black market sellers will not keep this easy-to-sell weapon for so long without making a sale, on the one hand, because this is an old gun, and the more you keep it, the more it can't be sold at a high price;

"On the other hand, these are used old guns that require daily maintenance to ensure reliable performance, and can be used for the same amount of effort and time, after all, they are in the black market business for high profits!"

As soon as everyone thought about it, this was indeed the truth, and they all agreed with this statement.

Qin Bangcheng added: "Another point, although the number of 12 MP18 is not too large, the vast majority of sellers in the black market can't get it, not because of financial strength, but because the quality of these guns is too uniform, and it is much more difficult to get 12 original old guns at one time than to get 12 new guns, imitation guns or new MP38s!" ”

It's not hard to understand this, MP18 has been born for more than 20 years, and it has been almost 20 years since it first entered China, and then MP28, MP38 and various imitations have emerged in an endless stream, and it is easier to get any new gun than this half-old MP18!

At this time, Li Xiaoyu suddenly said: "In addition to the Japanese, the Kuomintang can also take out these guns!" ”

Hearing this, everyone was stunned and didn't know how to answer - theoretically it was possible, but if someone on the Kuomintang side did this, the nature would be too bad, and the consequences would be something that everyone didn't want to think about.

Li Junhao waved his hand and said, "Don't think about this first!" Go ahead! He actually thought about this problem, but he really felt that it was impossible, needless to say, the military commander, who also had this ability, would not dare at all! The rest are the leaders of the Kuomintang, but they have no reason to do so!

Jiang Anhua, the head of the operations section, said: "Boss, I have arranged for the monitoring of No. 76 and the brother of the Japanese gendarmerie to report that I have not found anything abnormal in the past few days, but I heard about Liu Geqing, so I am a little suspicious that the little devil named Akagi Qinzhi is behind the ghost!" ”

Well? Li Junhao admits that he has neglected this devil a little! He hit and humiliated this guy in front of him twice, it is very reasonable for him to take revenge on himself, and with the identity of this devil, he also has this ability......

Wang Renqiang shook his head, but he didn't immediately say what he thought, but motioned to the last section chief, who had been silent, to speak.

The head of the internal affairs section, Telep Hofen (Bi), is the chief housekeeper of the investigation department, usually a little low-key, but he is a person with a show, Li Junhao once checked his file, knowing that he is a high-achieving student who graduated from the University of Brussels, and has good attainments in telecommunications and machinery, not long ago he has secretly arranged for him to set up a telecommunications detection room of the investigation department, so that he is also in charge, but this is investigating the case, what role can it play? He was curious.

Huo Fen is a light brown haired, thirty-year-old, somewhat urbane man with glasses, who has been silently drinking tea and listening since he came in, and was then signaled by the minister before he spoke: "Boss (he is the first foreign police officer to call him that), this afternoon, Minister Wang came to me and carefully checked the telephone line in your office to make sure that there was no stringing or eavesdropping, at least not within the police station. ”

Hearing his words, everyone immediately became energetic, this means: Is there a possibility that the director's office phone has been tapped?

Hoffen continued: "After confirming this, with the support of Minister Wang, I connected the telephone lines of the director's office with three multimeters, and tested the voltage and current changes when hanging up and making and connecting the phone fifteen times, and found that there was a considerable deviation from the normal value, with a variation range of more than 40 ......percent."
