The average detective knows what kind of gun the bullet is fired from, but this is enough for an arms smuggler, and there is always a track to follow of a bandit like this who uses the same weapon in large quantities.

The pit bull revolver is designed to be a personal self-defense weapon, not only slow rate of fire, but also short range, not very suitable for use in home care, can only play a little role in urban street fighting, so the sales volume in the whole arms smuggling has not been large, not a large volume of arms smuggling, only large arms dealers have inventory.

In Shanghai, only Sun Wei and Huang Jinrong were able to sell bulldog revolvers in such large quantities, and after the robbery of the Xiangfu gold store, Sun Wei asked Sun Li to investigate the sales books of pit bulldog revolvers, and happened to find the sales records of nine pistols, so he sent someone to investigate the buyer's situation.

In the era of the late Qing Dynasty, anti-reconnaissance technology was already a very high skill, and it was naturally impossible for a small deflated person like Sui Yongzhi to understand it, and they only thought that everything would be fine if they hid themselves from being discovered after the deed was completed, but they did not know that the clues in the previous preparations might betray them.

The gold, silver and jade looted by the Guangdong Associated Press from the Xiangfu Gold Store alone weighed hundreds of catties, and its total value had reached nearly 100,000 taels, which was half of the wealth of the Xiangfu Gold Store.

Such a large batch of gold, silver and jewelry is naturally not something that ordinary pawnshops can digest, and even if the pawnshop originally intended to take over, the news of the transaction cannot be completely blocked, and the government and the owner will naturally be able to detect the rumors, so Sui Yongzhi has died down since he robbed this business, and he will only sell it in a dispersed manner after the matter calms down.

After the predecessor Sun Wei turned the object of suspicion to the Yuelianhe and Sui Yongzhi, he sent his own Sanguang yards to infiltrate the Yuelian, which was expanding vigorously, and then after more than half a month of investigation and covert visits, although he did not find the exact location of the gold and silver jewelry, he was able to determine that the jewelry was indeed robbed by the Yuelian.

The reason why the predecessor Sun Wei did not take immediate action after detecting the robbers was that on the one hand, he wanted to survive the foreign bosses who wanted to catch the house, and on the other hand, the Sanguang yards he sent to the Yuelian News Agency had not yet found the hiding place of the stolen gold, silver and jewelry, and according to the information from the investigation, this location was only known to Sui Yongzhi himself.

After all, the concession is different from the Manchu government, and any criminal case needs to be tried by the public party, and it is difficult to convict the public party in the absence of evidence.

In Sun Wei's view, hundreds of catties of gold, silver and jewelry are not a thing that can be hidden in the corner, and there are only three places to hide such a large amount of property, one is the safe of the bank, one is the mezzanine of the family's house, and the last place is the most common means of the rich man in the countryside, which is directly buried in his own yard.

The first bank safe was quickly eliminated by Sun Wei, because he knew that the major banks in China had not yet opened this business, so the rest was only placed in the mezzanine of the house or buried in the yard.

In order to find the specific location of Sui Yongzhi's hidden stolen gold, silver and jewelry, the predecessor Sun Wei had already found out the real estate owned by Sui Yongzhi and the Yue Lianshe Society, but although these two concealment methods were the most stupid, they were also the most effective, otherwise they would not have been used by the landlords and wealthy for thousands of years.

What the predecessor Sun Wei can't do doesn't mean that Sun Wei himself can't do it, Marx once said that science and technology are productive forces, and this kind of problem that has plagued treasure hunters for thousands of years can still be deciphered with advanced science and technology, and the tool to decipher it is just a small metal detector.

In the previous life, the metal detector has been regarded as a tool on the bad street, and its types alone are divided into electromagnetic induction type, X-ray detection type, and microwave detection type, which has brought great convenience to the personnel of archaeological work and tomb robbery.

The manufacturing process of metal detectors is troublesome and troublesome, and it is simple to say, mainly depending on what kind of metal detector is needed.

Like X-ray detection type, microwave detection type of these two metal detectors in the manufacturing process is a lot of trouble, is Sun Wei with the current resources in his own hands can not be manufactured, and for the most primitive metal detector like electromagnetic induction type is much simpler, its material is nothing more than a few coils, instruments, dry batteries, this is the previous life in high school exposed to the knowledge of physics eddy current.

Regarding the robbery of Xiangfu Jindian, Sun Wei is confident that he can solve the case within two days, and one of them is still prepared for the manufacture of metal detectors, but considering that it is too deliberate to solve the case so quickly, it is easy to make the arrester think that he actually knew who was committing the crime, so he asked the chief inspector for seven days.

In the report, Jiang Xue described in detail the entire process of Sun Wei's leading the central patrol house patrol and arrest operation and the entire process of the trial of the Li Gang incident, the length of the article is at least tens of thousands, and I don't know how Jiang Xue wrote it, and the text together with the photos of Li Gang and others being arrested occupies the entire page of the newspaper.

Perhaps it was a deliberate flattery of Sun Wei, Jiang Xue did not write about Li Gang's request for Sun Wei to let his family go in the report, which made Sun Wei couldn't help but breathe a sigh of relief after reading the report, after all, a perfect hero and a hero with bad deeds and purpose are not the same in the hearts of the people.

After reading the report of "Declaration", Sun Wei picked up the number tray automatic telephone on his desk, and then dialed the phone number he had asked for from Jiang Xue during the interrogation.

"Hello, this is Jiang Mansion, who are you looking for?" The person who answered the phone was a woman, and her voice sounded quite young, but even if the phone was lost a lot, Sun Wei could hear that the voice was not Jiang Xue's.

"Hello, I'm Inspector Sun Wei of the Central Patrol House, and I'm looking for Miss Jiang Xue Jiang." Sun Wei said softly.

"I'm sorry, my young lady is resting, if Inspector Sun has something, I can convey it to you after the young lady wakes up." The woman on the other side of the phone said.

"Oh, it's not a big deal, when your young lady wakes up, please help me convey it, just say that Sun Wei thank her for her mercy, and I will invite him to dinner when I have time." Sun Wei said

"Okay, is there anything else Inspector Sun has to do?"

"No, thank you, goodbye."

"Goodbye!"

At the Jiang Mansion in the French Concession of Shanghai, a middle-aged woman who looked graceful and luxurious in both her dress and her expression and posture answered the phone and asked, "Xiaohong, whose phone is it?" ”

"Madam, it's Inspector Sun Wei from the Central Patrol House of the Public Concession, who called and said he was looking for the eldest lady." Xiaohong replied.

"It's him again, he hurt our Xiaoxue all night yesterday, and today he came to disturb Xiaoxue again. Xiaohong, did Inspector Sun say on the phone that he was looking for Xiaoxue? Jiang's mother, who loves her daughter very much, said indignantly.

"Inspector Sun didn't say anything specific, just asked me to help him convey a thank you to Miss." Xiaohong said.

"Got it, go get busy." Jiang Mu nodded and said.

Jiang's mother went upstairs to see her daughter after Xiaohong left, but she bumped into her daughter who had just gotten up in the corridor.

"You kid, you only slept so late yesterday, why did you get up so early today?" On the corridor, Jiang's mother said to Jiang Xue, who was already dressed neatly, with a look of pity.

"Hehe, thank you for your concern. However, the newspaper has recently been revised, and there are a lot of things to deal with, so I can't watch everyone busy and sleep at home, so that others will gossip. Jiang Xue smiled like a flower and dragged her mother's arm and said coquettishly.

"Let them gossip when others gossip, you have to marry a girl sooner or later, what's the use of a good job." Mother Jiang pinched her daughter's cheek lovingly, and then continued while following her daughter downstairs: "You don't want to go to the newspaper office today, I have recently called the editor-in-chief of your newspaper and asked for leave for you." ”

"Mother, how can you do this, and don't ask me if I agree or not." Jiang Xue was dissatisfied with her mother's decision, and said coquettishly in a long voice.

"You're my daughter, can't I, a mother, restrain me?" Jiang's mother said.

"Mother, now we are all about freedom and equality, and everyone should have their own rights and decide their own affairs, even if they are parents, they can't interfere." Jiang Xue retorted.

"Your father and I really shouldn't have sent you to study abroad, you see what a well-behaved daughter she was, what has become of her when she comes back, what kind of democracy and equality is when you open your mouth and close your mouth, and you have forgotten all the etiquette and religion of our ancestors." Mother Jiang said with a little remorse.

"Mother, the reason why our country is always bullied by foreigners is that our countrymen are too conservative, and only by learning the things of foreigners can our country become strong." Jiang Xue said.

Although Jiang's mother is Zhu Baosan's daughter, Zhu Baosan has not yet developed when she was born, so she naturally has no ability to take her to the concession to receive a new type of education, and after Zhu Baosan has made a career, she has reached the age when she should get married, so this twist and turn made her only receive a few years of private school education, and she read most of the books that teach women's morality, such as "Female Commandments", "Internal Training", "Female Analects", "Female Fan Jielu" and other books that teach women's morality.
