"I...I don't remember..." Park Sangyou said at a loss, "But, but...that security guard is the seventh-level reformer I mentioned...he should have a gun...

As for the model of firearm I carried, I didn’t pay much attention.”

"Damn it, it seems those three people really came out of this place." Hound cursed secretly, took out a compressed biscuit from his pocket, tore open the package and stuffed it in whole.

Mouth - While performing this series of actions, his eyes were always staring at the front of the tunnel, and the assault rifle was tightly tucked under his arm, maintaining a posture ready to shoot at any time.

Everyone immediately stood up and grasped the weapons in their hands - no one spoke anymore, which made the sound of hounds chewing biscuits very clear in the tunnel.

Ke Lan raised his palm and made a "slowly advance" gesture, letting Valentina control the body and slowly walk forward.

"Leiton, go check this bullet casing." Ke Lan said softly.

Layton nodded, jumped off the back of the mecha, landed on the ground, bent down and picked up the bullet casing.

"It is indeed a 10mm caliber Ark series full-power bullet. The inscription on the bottom is that it was a new product shipped by the military arsenal in 1948..." Layton said, "Furthermore, judging from the propellant residue, the deformation of the shell and the firing pin

Judging from the collision traces, this bullet should have been fired in fully automatic shooting mode...at worst, it was a long burst of more than five rounds."

"Can such a thing be seen?" Zhuo Ligetu said in astonishment.

"Well... I have touched many guns and bullets, so I can still see some differences. What's more, the big guy's original occupation is dealing with weapons, so his judgment is still very reliable." Hound explained the current situation.

, he had no intention of joking anymore.

"But the problem is that if it was fully automatic shooting, this should not be the only bullet casing left behind...could it have been picked up by someone?" Ivan asked.

"Everyone get out of the car." Ke Lan said in a deep voice, "Change to the No. 4 advancement formation and continue to move forward."

The No. 4 advancement formation is a team-sized infantry-tank coordination formation. It is generally used for frontal assaults on local positions that have been washed away by artillery and missiles. Although the reconnaissance team does not have tanks or armored vehicles, it uses mechas to replace combat vehicles.

It is also completely feasible.

Valkyrie One was at the front to clear the way, with Zhuoligetu and Layton in heavy armor on both wings, responsible for fire containment. The others used the mecha as a cover to quickly follow up - everyone put their own

His index finger was pressed against the trigger guard, ready to fire at any time.

After advancing fifty meters along the tunnel, they picked up more than a dozen almost identical bullet casings, which made everyone's nerves become even more tense.

The area where the battle took place should be not far ahead.

"There seems to be something on the ground in the distance?" Layton whispered, turning the beam of the searchlight.

It was a gun, a gun with an exploded barrel. The barrel opened like petals, the torn steel bars were tangled together, and there were still traces of the metal melting and then solidifying again on the surface.

A large-capacity c-mag drum lies quietly not far from the rifle.

"It's an Ark-199 squad-level light machine gun... Judging from the length of the barrel, this one should still be a carbine type with the barrel cut off." Layton said, "Because the caliber of the ammunition used has not changed, it is still a 10mm full-power bullet.

Therefore, the recoil of this thing is much greater than that of the Zero-1 rifle. Without a bracket, only enhanced people or modified people can control the gun in fully automatic shooting."

"My troops never choose this thing. Among squad-level light machine guns, there are many better choices than this thing. This thing has no merit except that it is easy to carry and can be interchanged with the Ark rifle." Hound said.

.

"There is still a difference between the Ark-199 and the Zero-1 rifle... In order to support long-term continuous shooting, the barrels of the original Ark-199 have been specially strengthened. The content of the Nino alloy is around 8%, which requires

The barrel is much more resistant to grass than the Zero-1 gun... To be honest, this is the first time I have seen an exploded barrel.

Ark-199." Leighton shook his head. "Although it is a machine gun, its usage must be mainly long burst and short burst. There will be no problem with the performance of the original barrel. Unless the user fires it in one go.

Only when four or five drums are empty, and there is almost no gap in between, can the chamber explode."

"Then maybe it's not the original barrel?" Hound said.

"It's almost impossible. I think... their project shouldn't be short of such funds, right?" Having said that, Layton still stepped forward and picked up the exploded machine gun.

"It's the original barrel... Hiss, I'm afraid it fired at least a thousand rounds in a row..." Layton pulled out the "Blooming" barrel and took a look at it.

A large-capacity c-mag drum can only hold 80 rounds of 10mm caliber Ark series full-power ammunition, but who would carry a dozen heavy and obstructive c-mag drums on their body?

Even the ammunition chain box weighing tens of kilograms carried on the back of a heavy-arms fireman can only hold 500 rounds of ammunition.

"Look, there are blood stains on the grip and receiver of this gun." Hound said, "Could it be that the gunman was injured when he exploded the chamber? Didn't he even wear armor or protective clothing?"

"It's not like that." Layton shook his head, "If the man was really injured by the explosion, the blood wouldn't have reached the handle."

"It's not just the explosion of the chamber. If he hadn't taken off his armored gauntlets and gloves, there shouldn't be any blood stains on the handle." Ivan said sharply, "But this is good news for us. Apart from these blood stains,

, there are also a lot of muscle tissue fragments left in the anti-slip groove, at least we can use these clues to determine the identity of the gun owner."

There are two most accurate ways to determine a person's identity: bone scans and DNA information. Unlike the old era, which only collected DNA information from people with criminal records, on the Ark, everyone's DNA information is collected after birth.

It will be entered into the archives and tied to his personal file.

The blood stains and muscle tissue were carefully scraped off with steel needles and put into glass tubes containing reagents, and then the glass tubes were inserted into the detection equipment. Fortunately, the reconnaissance team's mission this time was to search and rescue survivors in the mining area.
