"Uh......h Kalala......"

The noose disc is slowly locking the safety valve

The steel cable that was put into the cave from the construction truck had bottomed out, and there was no movement in the tunnel. It seems that the intelligence of the defense equipment inside has determined that the noose is not worth triggering its defense arrangement.

Liu Dongfang and his two comrades-in-arms were about to go down to the tunnel, when Liu Yuxin hung the laser Gatling in his hand behind the mecha and took the lead in holding the steel cable

"Let me go down first, right? I have a wider detection range than you."

Liu Dongfa nodded at his two companions and made way for Liu Yuxin

Liu Yuxinxin slid down with her hands and feet clamping the cableway, and dived rapidly with a long series of radiant sparks in the piercing friction sound.

"It's coming!"

Just when Liu Yuxin descended to more than two hundred meters, the frozen soil on the four walls of the cave began to show traces of cracks everywhere, and small black spiders squeezed out of the cracks and rushed to the surface of Liu Yuxin's mecha desperately.

The few spiders who were lucky enough to climb onto the mecha let out squeaky screams, and then exploded into a cloud of white light at the same time, and in an instant, bright white arcs swam around Liu Yuxin's mecha's body, and the crackling electric shock sound was endless.

The mecha's display device flickered slightly a few times in the violent electromagnetic shock, and then returned to normal.

"Luckily, I was prepared!"

After learning that she might suffer an electromagnetic attack below, Liu Yuxin deliberately strengthened the mecha's electromagnetic resistance, and now it seems that this cautious decision is wise. This small, defenseless spider has a power that is extremely asymmetrical to his appearance. If left unprepared, it is estimated that most of the active Union equipment will be paralyzed into a pile of scrap metal due to the burning of electronic components.

"Tom!"

The mech's foot armor slammed into the hard ground at the bottom of the tunnel, crushing several self-exploding spiders that had barely had time to hide in the cracks in the walls.

"Brother Liu, there are a lot of powerful self-detonating electromagnetic spiders in the cave, and my laser Gatling circuit has been burned out, you have to load up the electromagnetic protective equipment before coming down."

After Liu Yuxin finished speaking, she turned on the searchlight on the mecha and transmitted the situation at the scene with images.

Now he was in what looked like a huge artificial tunnel. Meteorites tens of meters in diameter fell from the sky, piercing the surface of the earth and cracking the brittle and hard permafrost, tearing the tunnel apart and collapsing part of it, but the general structure remained intact. The smooth and smooth walls and the hard floor made of unknown metals show the extraordinary level of craftsmanship here. Liu Yuxin looked around for a while, but didn't find the demon seed that was supposed to be here.

"Tom"

"Tom"

"Tom"

With three loud bangs in a row, Liu Dongfa and his teammates landed one after another, one of them still carrying a huge storage box. There is no doubt that they have also been baptized by spiders, and there are scorched black marks everywhere on the silver-white armor on their bodies.

"How? What did you find? It is not supposed to be a natural formation, but the database does not say that there is such a man-made structure under the Antarctic land. ”

The meaning of Liu Dongfa's words is also very clear, this is not the property of the alliance, and it may not even be built by humans.

Liu Yuxin pointed to the black road

"These are not the materials we use conventionally. I just tried it, and those black metals are so hard that they can even be compared to our external armor."

It turned out to be paved with the external armor of the battleship! How bad does that have to be?

"What to do? Are we divided into two ways? ”

Liu Dong pointed in two opposite directions

"It's better not to"

Liu Yuxin took off the laser Gatling with her backhand, took out the spare parts from the storage box, and replaced the burned-out starting circuit

"Judging by the defensive arrangement here, their level of technology is at least not lower than ours. Before we know their attitude towards us, we should gather together and have a plan for each other."

Liu Dongfa and the three of them switched to the squad channel to discuss Liu Yuxin's proposal, although Liu Dongfa trusted Liu Yuxin very much, but for a soldier, the first place is still to complete the task given by the superior.

"What do you think? I think it's better to act together."

Liu Dongfa is naturally biased towards Liu Yuxin's proposal.

"Brother Fa, this place is a bit evil, I think what Brother Yuxin said is very reasonable. I don't know which group of turtle grandsons live in this place, and the door is a dismount. We can't let them take advantage of it."

"Brother Fa, let's act together. The technological level of this force hidden underground is not lower than ours, so we can't be sloppy."

Seeing that his team's opinion had been agreed, Liu Dongfa cut back to the public channel

"So let's choose a path"

Liu Yuxin pointed to the left with her hand

"That's it!"

Although there was no clue about finding the demon seed, Liu Yuxin always felt that something kept calling for her at that end. If you don't figure it out, you won't feel comfortable.

After walking along the wide road for a while, the eyes suddenly opened up. They came to a hall where the flat metal road came to an abrupt end.

"Oh my god! What happened here? ”

Looking at the hall in front of him, which did not have an inch intact, one of the team members couldn't help but exclaim

In this hall of thousands of square meters, the walls around it are full of craters burned by energy weapons, one after the other, one on top of the other, and all the eyelets are like hornet's nests.

"It's an alien invasion!"

Liu Dongfa picked up a piece of carapace on the ground, held it in his hand, and analyzed it with a mecha instrument.

He had seen a tragic battlefield like this not long ago. Could this be another relic of the Giants? But why did the xenos clean up the battlefield this time?

Why not consider that it was the underground civilization that won the final victory in this conflict? The fact that the tunnels have not been repaired so far speaks volumes.

"Be careful, everyone, the xenos may not have left!"

Liu Dongfa put the carapace in his hand in the storage space of the mecha and opened the safety of the electromagnetic rifle in his hand

High-level xenomorphs can even lie dormant for tens of thousands of years. Although this place may seem to have been free of biological activity for decades, it does not mean that it is safe.

"Little Five, compare the information of these carapaces to see if there are any creatures that match"

"Okay!"

Xiao Wu responded crisply

"Xiao Wu is the al butler of my personal terminal, linked to the database of the 521 base"

Due to the deactivation of his terminal not long ago, Liu Dongfa and them saw Xiao Wu for the first time, and Liu Yuxin introduced it for everyone. In his mind, Xiao Wu has always been a friend, and it is a necessary etiquette to introduce it to others and make it accepted by the public. As for the constitution of the Union, to hell with it! Since waking up, Liu Yuxin has never seen an evolutionary who truly abides by the law.

"Found it! The carapace displayed by the owner is highly similar to the shell of a multi-legged ancient rock shale, but hundreds of times harder than the original, and is likely to be a completely new xenomorph that has not yet been discovered! ”

This place is not without xenos! This discovery shocked everyone. So why have they never been found on the ground? Could it be......

"Their war with the underworld civilization is still not over!"

Liu Dongfa and Liu Yuxin said in unison

By this time, the course of events had been slowly outlined.

The Antarctic continent is not not alienated, but because the permafrost is easy to crack, most of the meteorites fell into the interlayer of the ground, and after the wind and snow covered, they were all isolated to the ground, quickly catalyzing a number of species sleeping on the permafrost.

And the reason why these xenomorphs have never shown up is undoubtedly the demon seed.

At the beginning of the fall of the Demon Seed, the relatively weak xenomorph did not prevent the underground civilization from collecting it. But they still keep the subterranean civilization under their bay. Over time, the xenomorphs grew stronger and slowly began to advance into the fortress. And this hall, which has been reduced to ruins, should be an important entrance to the fortress of underground civilization.

After Liu Dong sent them to report the information and speculation, the command was silent for a while. Then came the order of the lieutenant general

"Keep going!"

Bastard! They are well aware of what's going on here!

You know, there might even be a whole alien race here! Continuing to investigate is undoubtedly self-defeating! Shouldn't the normal procedure be to suspend exploration and return to base in the long run?

At this time, Liu Dongfa and the others also somewhat understood the meaning of the high-level, and for a while there was only the sound of heavy breathing in the channel. Silence lasted for a few moments

"Keep going! At least we need to figure out how much of a threat these xenomorphs can pose to humanity."

Liu Dongfa thought about it, isn't his duty to find out all potential dangers for human beings? The degree of danger does not justify oneself in passing the buck.

He turned his head to face Liu Yuxin's mecha again

"It's too dangerous ahead, so you might as well go up. You're not an active-duty serviceman, they won't say anything"

"Brother Liu, you haven't been with me for a day or two, do you say I'm that kind of person?"

Liu Dongfa was speechless for a while, and reached out for a long time to pat Liu Yuxin's shoulder.

"Good brother, it's my honor to know you!"

"It's also my pleasure to meet you!"

Another hand came up

"We don't believe it, just a few bugs that don't know what they look like can keep us here!"

"Hey, you two took both of his shoulders, what about me?"

The last person walked over and gently hammered Liu Yuxin's mecha in the chest

"Brother, enough men! I'll invite you to drink when you go back! ”

Liu Yuxin smiled heartily

"Okay, we're done! After going back we went to the best bar in the safe area for a drink. I'm in for a treat, don't fight with me! I just happened to make a small fortune recently. ”

"For the Alliance!" x3

Three hands were placed on top of each other

Liu Yuxin hesitated for a moment and put her hand up

"For the ...... of humanity"
