Alien Relic Hunter

"Fuck, fuck..." The emotional hound said "fuck" several times in a row, "If there is fucking oxygen in this damn place, why are the experts from the three institutes fucking Will he be suffocated to death?"

Although the series of shouts by the hound were extremely pregnant, everyone still understood what he wanted to express, and the atmosphere in the tunnel suddenly became weird.

Layton silently opened the mask of his helmet, tried to take a few breaths of the air in the tunnel, and then nodded to Ke Lan: "The results of my artificial lung show that there are no toxic gases in the air, and the oxygen content is within More than 20%...just like most places on Alpha Planet, it can fully meet human survival needs."

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

"Their cause of death was suffocation, and the oxygen content in the tunnel where the bodies were found was less than five percent and was full of highly toxic gases." Ivan said calmly, "The composition of this tunnel and the air there are not the same. Are not the same."

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

"It's a pity. If they could have come this far, they might not have been 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. If they still bravely walked in, isn't this looking for death?" Layton asked doubtfully, "Could it be that... we are going in the wrong direction?"

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

"Fuck... I feel like the hairs on my back are standing on end." Hound hurriedly put the lighter back into his pocket and picked up the gun, "Are we... still going forward?"

"Could it be that... we accidentally passed through another one-way transmission device?" Aya Breya looked at Ke Lan, "In this way, the air composition of the two tunnels 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 go back to the corpse." Ke Lan turned around and looked at the long lines drawn with fluorescent dye on the ground, "Going back and forth will waste nearly twenty hours. , and the results may not be obtained.”

"Then what are your plans?"

"Keep moving forward." Ke Lan said, "I'm very curious about what those three experts discovered while they were still alive."

"Damn... I thought it was okay at first, but now that I'm doing this, the dark tunnel in front of me always feels like a big mouth eating people." Hound said, taking out a handful of compressed biscuits from his backpack and giving them to everyone. , "Everyone should first put a piece of compressed biscuit on him. If there is any unexpected situation and it is too late to eat, just take a piece of biscuit to deal with it."

"To be honest, if there is any emergency later, I'm afraid I won't even have time to chew biscuits." Layton stuffed the biscuits into the carrying bag on his chest. "Besides, when a battle breaks out, it's probably I don’t feel hungry anymore.”

"That's because you're not so hungry that you have hypoglycemia." Hound stood up and poked a chestnut on Layton's helmet. "If you have been to the frontline battlefield, you will find that many soldiers chew dry food while fighting. Those who are shooting at the same time have to eat even if they don’t have time... People are like rice and steel, do you understand?"

"Indeed, although the adrenaline secreted when you are nervous can temporarily block the brain's perception of hunger, the energy consumption is real. Even in a fierce battle, you may lose your eyesight and fall to the ground." 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 the consequences. In my opinion, a guy like you with no actual combat experience will still be a new recruit even if he retires." Hound began to push further.

"Can you blame me? I applied several times to be transferred to a combat unit, but my superiors didn't agree. Alas, there's nothing I can do. It's all because I'm too skilled, and the big guys in charge of logistics are reluctant to send me out. Tsk, tsk, tsk." Layton countered not to be outdone.

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

"Fart, when I retired, I held the rank of lieutenant!"

"Is a lieutenant great? If you are really capable and can serve as a seventh-term sergeant and hold the title of first-class sergeant major, then you are still promising. A lieutenant is a hammer, and the front-line troops can make a lot of money."

"If I could become a first-class sergeant as a mechanical repairman, I would have joined the equipment department of the institute long ago." Layton said, suddenly patting the Valkyrie One under his butt, "But then again, now this The situation is not bad either. Those top guys from the research institute and the top mechanics from the Yip Consortium have spent a lot of money to build things, but I haven’t been able to take them apart for fun. Hey, if I can reach this point, my life is considered complete. ”

"Looking at your potential, I don't even want to talk about you anymore. You've simply brought me down." Hound complained.

This time, Ke Lan did not stop the two of them from bickering. After being pulled by them, the originally tense atmosphere disappeared without a trace. Even Aya, who had always had a straight face, relaxed and whispered to her hands. The agents started chatting.

Of course, the content of their chat was much more serious than that of Hound and Layton. They were basically discussing how to deal with emergencies and follow-up action route planning. Although the current situation is not optimistic, at least No one showed too many negative emotions.

But the mecha suddenly stopped.

Everyone stopped talking almost instantly and grabbed their weapons.

About thirty meters ahead, a brass-colored bullet casing lay on the ground.

The shell casing stood out on the spotless metal floor.

The alpha civilization's weapon list does not include metal-cased fixed-loading ammunition. This kind of thing can only come from the human world.

"That is a ten-millimeter caliber full-power cartridge case. It is the ammunition used by the Ark-01 type and a series of derivative models of the same caliber." Layton said silently.

"Park Sangyou! Do you remember what weapons those people who entered the lava channel carried?" Ke Lan suddenly turned his head and shouted to the rescue cabin.
