Alien Relic Hunter.

Chapter 464 Bullet Cases
"Fuck, fuck..." The emotional hound said "fuck" several times in a row, "Since there is fucking oxygen in this **** place, why the fuck are the three experts from the research institute?" Will he be suffocated to death?"

Although the hound's series of yells contained a lot of content, everyone still understood what he wanted to express, and the atmosphere in the tunnel suddenly became weird.

Layton opened the helmet's visor silently, tried to take a few breaths of air in the tunnel, and then nodded to Ke Lan: "My artificial lung shows that there is no toxic gas in the air, and the oxygen content is at More than 20.00%... Just like most places on Alpha Planet, it can fully meet the survival needs of human beings."

"Isn't the cause of death of those three people suffocation? Then what killed them?" Ke Lan pondered.

"Their cause of death was suffocation, and in the tunnel where the bodies were found, the oxygen content was less than 5.00%, and it was full of highly toxic gases." Ivan said calmly, "The air composition in this tunnel is different from that in that tunnel." .”

"But I can't feel the wind at all." Ke Lan also opened the helmet visor, took off the gloves at the same time, put his finger into his mouth, moistened it with saliva, and raised it above his head, "Tunnel There was also no apparent movement of the air inside."

"Unfortunately, if they can come here, maybe they won't be suffocated to death." Layton sighed.

"Perhaps...they walked out from here?" Ke Lan paused, and then continued, "The direction of the three of them may be completely opposite to ours."

"Then they should have turned back in time when they noticed the lack of oxygen, and they still went in. Isn't that courting death?" Layton wondered, "Could it be that...the direction we're going in is wrong?"

"The place where the three experts would rather suffocate to death than escape, is this front?" Ivan turned his head and looked towards the front of the tunnel.

"Grass... I feel like the hairs on my back are standing up." The hound quickly stuffed the lighter back into his pocket and raised his gun, "Should we... continue to move forward?"

"Could it be... that we passed through another one-way transmission device unintentionally?" Aya Breya looked at Ke Lan, "In this way, the air composition of the two sections of the tunnel is completely different, and there is no gas flow The signs and the deaths of the three experts can be explained."

"If we want to verify this guess, we need to turn back to the corpse." Ke Lan turned his head and looked at the long lines drawn with fluorescent dye on the ground, "It will take nearly twenty hours to go back and forth. , and it may not be possible to get results."

"What are your plans?"

"Keep going." Ke Lan said, "I'm curious what those three experts discovered when they were alive."

"Damn... I thought it was alright at first, but now that I'm doing it like this, the dark tunnel in front of me always looks like a big mouth that eats people." The hound said, and took out a handful of compressed biscuits from his backpack and distributed them to everyone. , "Everyone take a compressed biscuit and put it on their body first. In case there is any unexpected situation and it is too late to eat, take a biscuit to deal with it."

"To be honest, if something unexpected happens later, I'm afraid I won't even have time to eat biscuits." Layton stuffed the biscuits into the carrying case on his chest, "Besides, when a battle breaks out, I guess I don't feel hungry either."

"It means you have never been so hungry that you have hypoglycemia." The hound stood up and chiseled a chestnut on Layton's helmet, "If you have been to the frontline battlefield, you will find that many soldiers are chewing dry food while fighting Those who shoot at the same time have to eat even if they don’t have time... People are like iron rice and steel, understand?”

"Indeed, although the adrenaline secreted when nervous can temporarily block the brain's perception of hunger, the energy consumption is real. Even in a fierce battle, it is possible to fall to the ground with one black eye and one head." Yi Fan added that as a doctor, his words are still very convincing.

"That's right, if you don't listen to the old man's words, you will suffer in front of your eyes. In my opinion, even if you have no actual combat experience, even if you retire, you are still a rookie." The hound began to push forward.

"Can you blame me for this? I applied several times to be transferred to a combat unit, but my superiors didn't agree. Alas, there's nothing I can do about it. It's all because my skills are too good, and the big guys in charge of logistics are reluctant to send me out. Tut tut." Layton counterattacked not to be outdone.

"Tch, if I had been in logistics, I would have been promoted to general officer long ago, and that fat pig of Maginot would have to salute me when he saw me...Look at you, you're still just a technical sergeant until you retire. Isn't it embarrassing?" Seeing that Layton dared to speak back, the hound immediately activated the yin and yang mode.

"Fart, I retired with the rank of lieutenant officer!"

"Is the lieutenant amazing? If you are really capable, you can be a non-commissioned officer in the seventh rank, and you can get the title of a first-class sergeant major. That's a bit of a promise. The lieutenant is a hammer, and the frontline troops can make a lot of money."

"If I could become a first-class sergeant major by being a mechanical repairman, I would have joined the equipment department of the research institute." Layton said, and suddenly patted the Valkyrie type under his buttocks, "But then again, now this The situation is not bad either. The things that the group of elites from the research institute and the top mechanics from the Yip Consortium spend a lot of money on are still being dismantled and played by me. Hey, to reach this level, my life is considered complete gone."

"Look at how promising you are, I don't even want to talk about you, it just lowers my grade." The hound complained.

This time, Ke Lan did not stop the bickering between the two of them. After being pulled by them, the tense atmosphere instantly disappeared without a trace. The agents chatted.

Of course, the content of their chat is more serious than that of Hound and Layton. They are basically discussing how to deal with emergencies, follow-up action route planning and other things. Although the current situation is not optimistic, at least Everyone didn't show too many negative emotions.

But the mecha suddenly stopped.

Everyone stopped talking almost instantly and grabbed their weapons.

About 30 meters directly ahead lay a brass-colored bullet casing on the ground.

The case stands out against the spotless metal floor.

There is no metal-cased fixed-loading ammunition in the weapon list of Alpha civilization. This thing can only come from the human world.

"It's a 01mm caliber full-power shell, which is the ammunition used by the Ark-[-] type and a series of derivative models of the same caliber." Layton said silently.

"Park Shangyou! Do you still remember what kind of weapons those people who entered the lava tunnel were carrying?" Ke Lan suddenly turned his head and shouted at the rescue cabin.

[PS Thank you Xu Ditai and Tudou for the 500 starting coins; thank you for the 100 starting coins who quickly surrendered and tipped. 】
