Although the necks of the deceased were completely severed as if they had been beheaded, as Conan had found at the scene, the relevant laboratory reports and bleeding status proved that it was a postmortem wound, and a large-caliber bullet in the chest cavity was the anterior wound, which was the most likely cause of death.

"Tell me, there's something special about that bullet, isn't it?" Gregory seemed to have been waiting for this answer, and only then did he concentrate. "Tell me, guess why I had to let you and the little girl do it, instead of letting two familiar people do it."

"That warhead, a large-caliber warhead, should be from a pistol in terms of volume, and the twisted shape of the end of that warhead seems to be more common in strong charges. In other words, a strong charge of ammunition fired from a large-caliber pistol. And another interesting thing is that there are no scratches on the bullet that has been squeezed over the rifling, and it feels like the gun used is a ......"

"Smoothbore pistol, right?" Gregory nodded, and finished what he hadn't said for Qianyu. "Don't you think it's a lot like something you gave someone?"

"Well, like I shot Gin at his smoothbore pistol." Qian Yu did not shy away from it, but nodded very dryly. "I don't think there are many people in the world who do this."

If other characteristics may be other people's firearms, such a large-caliber smoothbore pistol, I'm afraid only Gin will use it.

Smoothbore, this is something that has been abandoned in the minds of ordinary people, after all, the absence of rifling means that the accuracy of the fired ammunition will be very poor, and it will not meet the needs of most weapons at all.

However, this is not very important for weapons that do not pursue range, such as smoothbore guns for tanks and smoothbore guns for close-range combat. At such distances, even with smoothbore shooting, it is still effective to achieve sufficient accuracy.

And when the defect of the lack of accuracy of the smoothbore weapon will not have a serious impact, the advantages of the smoothbore itself will also be revealed - due to the production process and its own characteristics of the rifle, its structural strength will be damaged to a certain extent, and the loss in the firing process will be extraordinarily large, so the smoothbore will have stronger lethality and sustainable combat capability.

It was for this reason that Gin chose a smoothbore design for his pistol - even if he didn't care about the maintainability of the smoothbore, which no longer required Chiba to be busy all day, he would never allow a rifled gun to fire dozens of strong-charge ammunition and then explode, a design that might not even survive a tug-of-war. What's more, the smoothbore gun itself can withstand higher chamber pressure and accept stronger high-charge bullets, helping the 12.7mm large-caliber pistol achieve quasi-hand gun level power.

All of this is familiar to Chiba, because these are exactly what Chiba has personally finalized, and they are also the close-range weapons that Gin loves the most, as he updates and maintains them day after day.

And now, the traces of such a gun have appeared on Hotaru's friend.

Regardless of whether Hotaru was aware of this or not, Fujiwara was absolutely capable of discovering that this was the bullet used by Gin - although he was not officially in the establishment, the gossip he had heard from famous people in Belmode was enough to let him know that Gin was a madman who pursued combat power in such an extreme way.

This is the main reason why Gregory finally chose to let the two rookies, Chiba and Gray Hara, come to dissect, and desperately hide from Fujiwara and Hotaru. Before figuring out what was going on, Gregory needed to stabilize the two time bombs that could be detrimental to both the organization and Gregory because of this discovery.

"What do you think is going on?" Grigory asked in a deep voice. "As a firearms expert, I'd like to hear from you."

"Gin's gun, it doesn't mean that Gin fires," Chiba's language was quickly organized. "This is a large-caliber pistol with a strong charge, I think the average adult can't use it effectively if he is not trained, even if it is a master like Fujiwara's brother who has a relatively full understanding of firearms, and also has a better understanding and psychological expectations of strong charges, it also takes a certain number of run-in and learning to control it, right? And Gin...... He is now in the form of a child, according to you, and he has already become smaller by the end of August, and his physical qualities, such as strength and the like, are absolutely impossible to support such a large gun. This is true even if he has used it many times and accumulated countless experiences, because he has never shot a child like this. ”

"Hmm," Grigory nodded. "It's pretty much what I thought, but the question is, if it wasn't Gin's gun, who else could have fired it, and do you know of anyone who could do the same?"

"I've definitely lost my hands on the organization, after all, this kind of gun has a lot of limitations, and I think more people may choose to equip a short-barreled smoothbore shotgun at close range, which is much more threatening than a smoothbore pistol in close combat (I should have mentioned earlier that short-barreled shotguns have a larger scattering range, so they can hurt the enemy if they are not completely aimed at the enemy.) Chiba shook her head. "Ordinary people...... Rye, for example, was a well-known shotgun faction in the organization before he was exposed, and liked to wear short-barreled shotguns with a rope over his shoulders and hide them under his clothes. And Gin, as you know, wears a trench coat, which is too draggy, and the process of taking it out is not as good as that if you use a shotgun...... Slim-fitting shirts and suits are as convenient as suits, and they're also easier to stand out from a soft trench coat in the wind or similar. At the same time, although the shotgun may have the advantage of being easier to hit, the high-powered pistol is a more powerful choice as long as it can be targeted, and Gin has the reflexes and marksmanship to quickly lock on to the opponent - plus I haven't heard of Gin having a good taste for capturing enemies, no matter who kills him directly, so it is much more reliable to give him a pistol that can retain lethality after directly breaking through heavy body armor than a shotgun that can crack the bone at most when encountering heavy body armor. ”

"So, that is, this gun should not come from someone we know, but from someone we don't know, is that what it means?" Grigory summed it up this way. "It's a real nuisance...... But the serial cases on both sides have come to the door. ”

"A series of cases on both sides?" Thousand Feathers raised an eyebrow. "What does that mean?"

"The members of the organization's sniper team are constantly being assassinated, and their families are also threatened," Gregor used the cane in his hand to point at the information he had just put down, and pushed it in front of Chiha. "And the other one is this, the dead related to the water department, this Miss Nami is the second."

"These two ...... It can't be together, right? After searching for information, Qian Yu asked a terrible question. If the people who want to torture Sister Hotaru are the same people as the people who are not good for the organization, maybe it will be more convenient to explain the coincidence of time, after all, such a thing as serial murder can't happen at the same time for no reason, right? In particular, it occurs between two groups of people who are linked. ”

If the couple of Fujiwara and Hotaru is used as an intermediate hub, then the two sets of assassinations are completely corresponding—although Chiba didn't know about it, Grigory still knew: Fujiwara was in fact a former member of the sniper team, but because it was not officially formed, he never became a regular member.
