Walking in the vast desert, I could still look at a ray of sunlight to discern the direction, but the wind flew sand and rocks together, and I couldn't see the direction at all, so I could only rely on the perception of the earth's magnetic field to continue to move forward in one direction, but the speed of progress became quite slow.

groping forward in the yellow sand in the sky, all he thought about was how to go deep into the underground and completely clear the alien lair, thinking that the system was finally arrogant and prepared for a big benefit delivery with no difficulty task, but in fact, it seemed that it was not that simple to clear the alien lair.

Obviously, the nuclear bomb attack was aimed at the alien, but the underground cave was too deep and was not injured at all, it is certain that before the nuclear bomb was used, all the things such as ground-penetrating bombs and incendiary bombs were used, and they couldn't work at all, so the nuclear bomb was used, and obviously the effect was still not obvious.

Therefore, the task of clearing the alien nest is really not that simple, and the number of aliens is too much, and there are not a thousand but eight hundred in the previous wave of wild brushing, and it seems that the number has not decreased at all.

To be honest, I really can't figure out why these aliens have made such a huge nest in this desert, and they can breed so many of them, there are no animals in this desert at all, so what do so many aliens grow up eating?

Could it be that aliens can still eat sand directly? This is obviously unlikely, although the alien creature is strange, it is a carbon-based creature after all, and it must not be able to eat sand directly to reproduce.

So what else can be eaten in this vast desert, it is definitely not cannibalism, it has advanced hundreds of kilometers from the underground cave **, and still no cities and villages have been found, in fact, it is unlikely that there will be a dense population in this dry desert.

In addition to the occasional encounter of some snakes, insects, rats, ants and other small animals in the desert, these things are too small to become alien hosts, and of course they cannot parasitize and reproduce quickly. Even if the alien has evolved its own way of growth in order to adapt to survival and reproduction, and no longer needs to parasitize and reproduce in the body of large animals, but it always needs food to grow up directly from the larvae, but there is nothing in this desert, what is there to eat?

“…… Could it be that the Xenomorphs have evolved the ability to survive on oil? ”

Suddenly, I thought that when I fell into the cave just now, I vaguely smelled some oil, but I suddenly thought of an alien that could get nutrients from oil.

Speaking of oil, in fact, most of the oil should also be derived from animal corpses, and even some microorganisms can use oil as food, so it doesn't seem too strange that the perverted alien has evolved the ability to absorb nutrients from oil in order to survive and reproduce. As for the ability to dig tunnels, it is completely possible to absorb the genes of some animals that are good at digging holes to evolve the corresponding ability......

The more I think about it, the more I think it's possible, but if that's the case, it's really a big trouble, this desert area on the edge of the Mediterranean Sea seems to have an extremely large amount of oil deep underground, if those aliens can really rely on oil to reproduce, that amount is really terrifying to imagine.

If you want to completely wipe out the alien lair, unless you take a small nuclear bomb directly into the center of the underground lair and detonate it, only in this way can you completely destroy the deep-rooted lair, but the problem is that the mission time is only 12 days, where to get a small nuclear bomb in such a short time?

According to the analysis of some information collected when I was bored before, the US military has deployed a lot of tactical nuclear bombs similar to B-61 in overseas military bases, especially in European countries, which are quite small in size and can be easily loaded into the space-time channel, and they have stealth equipment and a magical hand-held laser cutting equipment, so it is possible to get a nuclear bomb quietly.

It's just that that thing should have a password, and even if you get it without a password and successfully send it into the depths of the alien cave, there is no way to detonate it, and it feels a bit of a headache to think about it.

……

The sandstorm gradually stopped, jumped and glided, the average speed of movement was nearly 80 kilometers per hour, and it has been moving in the northeast direction, because the location where the escape pod fell is relatively close to the Mediterranean Sea, it may be two or three hundred kilometers, and it is believed that it will not take a few hours to reach the Mediterranean coast.

There are many human cities on the Mediterranean coast, and as long as you foresee human beings, you can understand in detail what the current situation of the world is, and whether there is a large army of human beings preparing to launch a military operation against the alien lair. If there is really a large army of humans acting together, then he still has a considerable chance to take the opportunity to enter the depths of the alien lair and destroy the alien queen......

Suddenly, he heard the fierce machine gun sound in the distance, and immediately stopped jumping and gliding, but quickly ran to a large sand dune, took out his binoculars and followed the place where the gunfire came from.

However, a foot chariot was ambushed by more than a dozen aliens, but the situation was not as one-sided as in the movies of the former country, and the small force of human beings was easily ambushed and killed by the aliens.

In fact, several people in the infantry chariot were carrying large-caliber machine guns, especially the large-caliber Vulcan machine gun installed on the infantry chariot, which was simply a big killing weapon, and the aliens who rushed up were instantly beaten into a sieve and had no chance to get close.

It's just that the machine gun is easy to use, but it consumes too many bullets, but after a while, the ammunition was basically beaten, and although the dozens of aliens who were ready to ambush had all been shot, more than a dozen crawled out of the sand dunes not far away......

A few GIs cursed, and the sound of machine guns rang out one after another, but they quickly ran out of ammunition, and although they successfully shot seven or eight aliens, seven of them managed to avoid the attack without any serious injuries.

The equipped grenades were also thrown, but the results were almost equal to zero, the speed of the alien was too fast, and it was difficult for those flying shrapnel to cause any serious damage to the alien, and several soldiers drew their pistols one after another and continued to shoot, but unfortunately the results were still equal to zero.

Seeing that a few aliens were about to rush onto the chariot to complete the kill, those soldiers also took out daggers and were about to fight for their lives, Zhang Tiancheng, who had been preparing for a long time, finally launched a sniper operation.

It is said that although the moving speed of the alien is fast, it is also very fast for human beings, in fact, the moving speed is only fifty or sixty kilometers per hour, and when Zhang Tiancheng runs the true qi to his eyes, the dynamic vision is more than ten times faster than that of ordinary people, so in Zhang Tiancheng's opinion, those running aliens seem to be quite slow......

About 320 meters away from the target, the initial velocity of the reinforced heavy sniper bullet is about 1200 m/s, tracking the line of the alien forward slightly ahead of most of the body and firing decisively, after firing a bullet, the muzzle of the gun is instantly fine-tuned, aiming at the first half of the other alien forward route and shooting again.

After completing the shot, he instantly turned the muzzle of the gun again, and continued to aim at the next target, relying on the physical nerve reaction speed that far exceeds that of ordinary people and the stronger dynamic vision, he fired seven shots in a row in a high-precision sniper ......

Seven quickly approached the alien of the infantry chariot, four were killed on the spot, and the other three were also seriously wounded, and were shot by the ensuing reshoots, and in just over a second, several GIs on the chariot were about to kill themselves by drinking bullets.

He also put down his pistol and looked at the mysterious sniper who appeared on the sand dunes not far away, and couldn't believe that such a difficult sniper mission could be completed in such a short time in this world.

"Thank you...... You help...... We...... Delta 3rd Detachment ...... The ...... of the 15th Patrol Group "Seeing Zhang Tiancheng approaching, the captains of the soldiers finally said thank you with an extremely awkward Chinese, and by the way, they also reported their unit numbers.

I wasn't even curious at all that Zhang Tiancheng appeared here with an oriental face and a heavy sniper, so it was basically certain that this time to deal with the alien crisis should be the world's military forces united in a real sense.

"Thank you, everyone is human and should help each other, but I am a secret operation this time, and the ammunition is a little insufficient, can I go to your camp to replenish it?" Zhang Tiancheng talked nonsense, it was true to add some ammunition, and of course he wondered if there was a chance to contact the next one to kill the underground alien lair.

"No problem...... You can as much as you want, as long as you move your back...... Take ...... casually," the team leader assured directly.

"Then what are you waiting for, hurry back to the base!" As he spoke, he jumped directly into the chariot.

"Dude, our tank is broken, but reinforcements will be there soon!"
