The number jù is very poor, and I don't know how long it can last, so I implore everyone to support and let the ants see a little hope!

**************

Hotels, guest houses, Internet cafes, bathing centers, and so on are often the easiest places to hide dirt and dirt, so they are also the focus of this police investigation.

Everyone who has been involved in criminal investigation knows that generally if someone escapes and arrives in a city, they will generally choose such an inconspicuous place to stay, especially those places like black Internet cafes and black bathing centers.

There is no need for identity registration information at all, you can live casually, and the main thing is that the price is cheap and not attracting attention.

So in fact, as long as the police are serious and willing to sweep these places, even if they are cuddling grass and beating rabbits, they will definitely be able to find out a lot of people they want from these places.

However, Huanghai City has a population of more than 10 million, and the urban area stretches over 100 square kilometers, with thousands of hotels, guesthouses, Internet cafes, and bathing centers.

If you want to sweep all these places, it is not a workload that can be completed in one or two days, even if you mobilize all the tens of thousands of police forces in the city and do a big sweep, I am afraid that it will not be completed without three or five days of effort.

Wei Zhengming communicated with his superiors, but he used all the police forces that could be used in the city.

Even many old ladies who usually manage logistics and work in the office have all been sent out, this time the matter is not an ordinary case, this Wang Ba box, at least seven or eight provinces have committed crimes, and everyone has nothing to do with him.

But this time in Huanghai City, Wei Zhengming arrested him.

The reason why he wanted to arrest this guy was not only for his top flower feather and bright future, but mainly because of his strong sense of responsibility as a police officer.

Another point is that after this case. In any case, he has been appointed by the above to become the first brother of the Municipal Criminal Investigation Brigade, and at the same time enter the Standing Committee of the Municipal Bureau and concurrently serve as the deputy director.

Of course, this is also the reason why Jing Nan compromised and made concessions with the above, after he progressed to that position, I am afraid that he will not have much energy to supervise the criminal investigation situation on the side of the serious crime team, and at that time, his identity will probably be more of a politician. And not the police anymore.

So he wants to concentrate on doing a good deed and practical thing for the people before his identity is completely changed!

In the past few days, Wei Zhengming has been rooted in the office of the city bureau every day, waiting for the news ahead, and at the same time coordinating the city's police search and investigation.

All the soldiers in his hands were also scattered, and some of them were responsible for sweeping and touching the platoon. There is also a group of people, under the leadership of Shen Chunyang, who went to Yangcheng Prison, where the transaction was made.

Yangcheng Prison is a Class A prison around Huanghai City, and it is generally held in it. They are all serious offenders, life sentences, death sentences, death sentences and the like, and most of them are detained here.

Shen Chunyang took Li Xiangdong and An Jianing straight here. Mainly for one person, this person is named Qi Baoshan, and he was sentenced to life imprisonment. The crime is the crime of manufacturing and selling arms without permission!

If this Qi Baoshan is judged from the current point of view, this guy can be regarded as a talent, in the early years, he was a mechanic, and later he was able to make very precise firearms with very simple machinery by virtue of his own thinking.

Later, after the case was discovered, after this guy was arrested, according to his confession, in order to make guns, he also taught himself advanced mathematics, physics, and human body science and other professional knowledge.

If this is put in the United States, this is definitely the subject of an inspirational movie.

And if it were in the United States, with his skills, he could have earned a fairly high income as a pure handmade gun technician!

It's a pity that he was born at the wrong time, and he mastered the technology of making guns well, but the technology of reincarnation was rotten at home, and he was directly reincarnated in China.

At the beginning of his earliest entry into the industry, he relied on his own exploration to create a pistol with quite high accuracy and reliable performance, which was later discovered and reported, and the public security arrested him.

The local military industrial enterprises in Huanghai City started to love talents, and felt that this young man was good, loved to specialize, and had technology in his hands, so they pleaded with the public security and asked him to come over.

At that time, the people in the public security system saw that this kid making guns was a hobby, and it did not bring much danger to the society, so they agreed to the request of the military industrial enterprise.

So this guy turned into a technical commissioner at the Huanghai City Arsenal.

Originally obsessed with firearms manufacturing, now into the arsenal, this Qi Baoshan can be regarded as a dragon into the sea, after entering the arsenal, not only the technology has been improved by leaps and bounds, even the design concept and ideas have been greatly improved.

Later, his involvement was more extensive, from manufacturing pistols, to submachine guns, to rifles, and even bullets, and he soon became a technical pacesetter in the factory.

It stands to reason that he can be regarded as famous, and he lacks nothing, after all, the treatment of the arsenal is never bad, not to mention that he is such a technical expert.

It's a pity that this guy is a gun idiot with a short circuit, he thinks he is right to build a gun, but what is this gun used for?

This gun is taken out to kill! But he was stuck in such a small factory, designing and producing firearms, but after these firearms were produced, they were taken by the army to be realized, and those that were unreasonable were directly sealed.

Even if it's easy to use, it's also a gun in storage, and it's only taken out for people to use when it's usually trained, what is this?

The gun simply didn't play its intended role.

So this guy secretly produced a lot of guns privately, and then spread them to the society through various channels.

During that period, there were many gun-related cases in Huanghai City and even in Donghai Province, and the social security conditions deteriorated several times for a time.

The pressure on the leaders above and the commanders and fighters of the public security system is extremely great.

Later, several criminals involved in gun-related cases were arrested in a row, and finally Qi Baoshan was plucked out of their mouths.

And this guy was later sentenced to a life sentence for the crime of manufacturing and selling guns and ammunition without permission.

And this time, Shen Chunyang took Li Xiangdong and them to find this guy, mainly to ask one thing from his mouth, that is, whether the Wang Ba box had bought bullets from him.

Is there any communication between the two of them, after all, the bullet of the Wang Ba box, the southern fourteen-year pistol used is really too special, eight millimeter caliber.

Such a caliber is converted according to imperial units. 320 inches, such a size caliber, even foreign countries are rare.

Not to mention in China, there is no firearm that uses bullets of such caliber, so the Wang Ba box is not only an antique, but even the bullets he uses are also antiques.

Since it is an old antique, the number of bullets in the world should not be much, but this Wang Ba box has traveled through seven or eight provinces, and no less than ten cases have been committed.

Among them, there is no need to talk about murder and robbery, even if it is blocked by the police, there are two or three shootouts with the police, and countless bullets are fired.

According to approximate statistics, there are hundreds of rounds of bullet casings of eight-millimeter caliber bullets found at the scene alone.

In this way, this guy's bullets can be fully supplied, especially after the public security forces later identified those shells.

Except for a small number of antique bullets that are decades old and left behind, most of the other bullets are modern imitations.

This can't help but make people wonder, who made this bullet?

You must know that the manufacture of this bullet is not so simple, and the knowledge and manufacturing technology involved in it are even more difficult than making a rifle.

Without the guidance of professionals, it is difficult for ordinary people to be able to make professional bullets.

The Ministry of Public Security once calculated the lethality of the bullet casings left by the man and the bullets he fired, and the bullets fired by the Wang Ba box were no worse than the southern bullets used by the Japanese back then, and even more powerful than the original version, and more stable.

This shows that these bullets are not from ordinary people, but considering the current situation in the country, there are only a handful of people who can make such bullets.

And in the northern region, thinking about it, the only person who can make such a bullet is this Qi Baoshan who is imprisoned in this prison!

After he was arrested, he only confessed to a few cases of making and selling guns, but he was also an expert in making bullets, who knows if he made some bullets and sold them at that time?

After all, when he was in the Huanghai City Arsenal at that time, all kinds of machinery and equipment and raw materials could be accessed, and there was no monitoring equipment in the factory at that time, and there was no computer Internet transformation, so it was easy for the workers to use some leftovers to do some private work.

So everyone thought about it, and used this bullet as a breakthrough to find Qi Baoshan's head.

Even if he didn't make the bullets himself, given his relationship with the underground gun dealers, maybe he would know who made them.

As long as the person who can find the person who provided this bullet to the Wang Ba box, then the identity of the Wang Ba box may be found out earlier.

Find out the identity of this guy, then you are one step closer to arresting this guy.

This is the main purpose of Shen Chunyang and Li Xiangdong's trip to Yangcheng.

Along the way, Shen Chunyang introduced Li Xiangdong and An Jianing to the glorious deeds of Qi Baoshan back then, this guy not only has a hand in making guns, but also has very accurate marksmanship.

He is not only the technical backbone of the Huanghai City Arsenal, but also the No. 1 school gunner, and every gun produced on the production line has to be fired several times in his hands, and the accuracy and reliability of the gun have been determined...... (To be continued......)
