"But I can’t feel the wind at all." Kelan also wore a helmet and mask and took off his gloves. He put his finger into his mouth and held it over his head after wetting it. "There is no sign of tunnel gas flowing."

"It’s a pity that if they could get here, they might not be suffocated," Leighton sighed.
"Maybe … that’s where they walked out?" Kelan paused and continued, "The three of them may go in the opposite direction to us."
"Then they should turn back when they notice the lack of oxygen, and they should go in anyway. Isn’t this a death wish?" Leighton wondered, "Is it wrong for us to go in this direction?"
"Let three experts suffocate rather than escape from the place?" Ivan turned to look at the front of the tunnel.
"Grass … I feel the hairs on my back stand up." The hound quickly put the lighter back in his pocket and picked up the gun. "Shall we … go on?"
"Could it be … that we accidentally passed through another one-way delivery device?" Ayabuliya looked at Kelan. "In this way, the gas composition of the two tunnels is completely different, and there is no sign of gas flow, so the deaths of the three experts can be explained."
"If we want to test this guess, we need to turn back to the corpse." Kelan looked back at the fluorescent dye on the ground and pulled out the long lines. "It will take nearly twenty hours to get the results once and for all."
"What are your plans?"
"Go on," Kelan said. "I’m curious about what those three experts found when they were alive …"
"Mom … it feels ok now. I think the dark tunnel in front always feels like a big mouth." The hound said and took out a handful of compressed biscuits from his backpack and distributed them to everyone. "Everyone should take a compressed biscuit first. If there is any accident, take a biscuit to deal with one."
"To tell you the truth, I’m afraid there won’t be any emergency when I’m eating cookies." Leighton stuffed cookies into his chest carrying gear. "Besides, I guess I won’t feel hungry when fighting breaks out."
"That’s because you’ve never been hungry enough to have hypoglycemia." The hound got up and scratched a chestnut in Leighton’s helmet. "If you’ve been to the first-line battlefield, you’ll find that many soldiers have to eat while chewing dry food and guns in wartime … people are iron rice or steel, understand?"
"It’s true that although the renal gland hormone secreted when nervous can temporarily block the brain’s perception of hunger, the energy consumption is real, and even in fierce fighting, it is possible to fall down with one eye black," Ivan added. A doctor is still very confident in his words.
"I just don’t listen to the old man and suffer. At present, it seems to me that a guy with little actual combat experience like you is still a recruit even if he is retired." The hound is pushing his luck.
"Can you blame me? I applied for several times and wanted to be transferred to the combat unit. I didn’t agree. Alas, there was no way to blame me for being too good at managing logistics. Those bosses were reluctant to send me out. "Leighton countered not to be outdone."
"If I had been a logistics officer, I would have been promoted to a general officer. Ma Qinuo, the fat pig, had to give me a gift when he saw me … See if you are a technical sergeant after retiring?" Seeing that Leighton dared to talk back, the hound immediately started the got mode.
"Bullshit! When I retired, I was a junior officer!"
"Lieutenant is great? If you really have something to do, you can hang a first-class master sergeant title for the seventh sergeant, which is still a bit of a promise. The junior officer is a hammer and a front-line army. "
"I would have joined the equipment department of the research institute if I had been able to do mechanical repairs to the first-class master sergeant," Leighton said, suddenly patting Valkyrie on the bottom of my ass. "But then again, this situation is not bad now. The top mechanics of the research institute and Yip’s consortium have spent a lot of money to pound things out, and I have not taken them apart to play. My life has been complete."
"I don’t even want to talk about you because of your promise. It lowers my level," the hound vomited
This time Koran didn’t stop two people bickering by them, so the tension vanished. Even Aya, who had been keeping a straight face, relaxed and chatted with his agents.
Of course, their chat is much more serious than that of Hound and Leighton. They mainly discuss things such as handling unexpected situations and planning follow-up routes. Although the situation is not optimistic, few people do not show too much negative emotions.
But the mecha suddenly stopped.
They almost instantly stopped talking and grabbed their weapons.
There was a brass shell lying about 30 meters ahead.
This shell case is spotless, and the metal floor stands out.
There is no metal shell in the Alpha weapon list. This thing can come from the human world.
"That’s a 10-millimeter powerful bullet shell, ARK-1 and a series of derivative ammunition with the same caliber," Leighton said silently.
"PiaoShangYou! Do you remember what weapons those people brought into the lava tunnel? " Kelan suddenly turned to the capsule shouted
Chapter four hundred and fifty-nine Blasting gun
"I … I don’t remember …" Park Shangyou said with some measures. "But, but … that security guard is the person I have been to … he should have a gun … I didn’t pay much attention to what type of gun he was carrying."
"It seems that those three fucking people really came out of this place." The hound scolded a compressed biscuit from his pocket, tore the package and stuffed it into his mouth. During this movement, his eyes were fixed on the assault rifle in front of the tunnel and he kept a gun shooting positions tightly under his armpit.
Everyone immediately got up and grasped the weapon in his hand-no one spoke again, which made the hound chew biscuits very clear in the tunnel.
Koran raised his hand and made a gesture of "slowly advancing" to let valentina control the body and walked slowly forward.
"Leighton, you go and check this shell" Kelan said lightly.
Leighton nodded his head and jumped from the back of the mecha. He bent down to pick up the shell casing.
"It’s really a 10 mm Ark power bomb. Look at the inscription on the bottom. It’s a new product from the military arsenal in 1994 …" Leighton said. "Moreover, judging from the residue of propellant and the impact marks of the shell shell deformation, this bomb should be shot out in automatic shooting mode … at worst, it will be a long shot of five bursts."
"This kind of thing can also be seen?" Zorig figure some surprise asked.
"Well … you can still see some differences when you touch a gun and play more bullets. The big guy’s original occupation is dealing with weapons, and his judgment is still very reliable." The hound explained that he was not in the mood to joke about this situation
"But the problem is that if it is an automatic shooting, there shouldn’t be this one … was it picked up by someone?" Ivan asked.
"Everyone’ cars’" Kelan sank. "Change the No.4 propulsion system and move on."
The No.4 propulsion formation is a team-scale coordinated formation, which is generally washed by artillery and missiles in frontal assault. Although the reconnaissance team has no tanks and armored vehicles, it is feasible for the mecha to replace the chariot position.
The two wings of the front road of Valkyrie’s one-style roof are wearing heavy armor. Zorig Tu and Leighton are responsible for fire containment, while others follow up quickly with the help of mecha bunkers-everyone keeps their index finger close to the trigger retainer surface and is ready for fire at any time.
After advancing 50 meters along the tunnel, they found more than a dozen almost identical shell casings, which made everyone more nervous.
The fighting area should be not far ahead.
"There seems to be something in the distance …?" Leighton low said the searchlight beam turned in the past.
It’s a gun. The barrel of a blasting gun bursts like petals to tear the steel bars and entangle them. There are still traces of metal melting and solidification again on the surface.
A large number of c-mag drums lay quietly not far from the rifle
"It’s Ark－199 shift-class light machine gun … depending on the barrel length, it should still be the carbine type with truncated barrel," Leighton said. "Because the caliber of ammunition has not changed, the recoil of the 10-millimeter powerful ammunition station is much greater than that of a rifle. If there is no support, automatic shooting will have reinforcement or transformation personnel to control the gun."
"Our army has never chosen this thing. It is much better to choose this thing in the shift-level light machine gun. This thing is not only easy to carry, but also can be replaced with Ark rifles at will," said the hound
There is still a difference between ARK-199 and Type I rifle … The original ARK-199 barrel can support long-term continuous shooting. The content of Nino alloy is much more resistant to grass than that of Type I barrel … To tell the truth, it is the first time I have seen ARK-199 blasting chamber. "Leighton shook his head." Although it is a machine gun, the way to make it is definitely long-shot and short-shot. There will be no problems in the performance of the main original barrel unless the messenger hits four or five in one breath.
"That may not be the original barrel?" Said the hound
"It’s almost impossible. I think … their project should not be so bad?" Say so Leighton or stepped forward to pick up the machine gun that exploded.
"It’s the original barrel that’s right … psst, I’m afraid it’s less than one thousand rounds of continuous shooting …" Leighton pulled out the "flower" barrel and took a look.
A large number of C-MAG drums can hold 10 mm Ark power bombs, but who will carry a dozen heavy and obstructive C-MAG drums?
Even a heavy gunner carrying a chain box with dozens of kilograms of heavy ammunition is only 500 rounds of spare ammunition.
"You see there is blood on the handle and the case of this gun," said the hound. "It’s not that the gunman was injured when he exploded, is it? Did he even wear armor and protection? "
