There was no light in the cave deep underground, and they didn't dare to turn on the flashlight, because although the alien did not have glasses, it also had a photoreceptor organ similar to the human pineal gland, and if the light was turned on, even if it was an LED cold light source, there would still be a risk of exposure.

As for that kind of mysterious ability, if it weren't for the situation of silence, it wouldn't be able to really see everything around you, but fortunately, I had thought that I would encounter this situation, so I borrowed the assistance of two infrared cameras and AR glasses on two inlaid visors, and barely solved the problem of not being able to see things.

However, after some delays in data conversion, his vision was seriously affected after all, and he could only grope his way forward very slowly and cautiously, carefully avoiding some passing aliens with his keen perception.

Although the infiltration is quite smooth, the speed is really slow, maybe the speed of the advance is only a little more than a kilometer per hour, and in order to maintain the energy of the stealth chip to continue to maintain the Zerg, basically they will act for two minutes and then hide in a suitable place to rest for a minute.

It has been eight hours of cautious progress from the entrance of the cave, and it has been nearly ten kilometers in the underground cave**, but it still has not reached the real alien lair, and some sticky oil is often seen on the walls of the cave around, and from time to time there will be some eating aliens.

Those aliens really took the oil as food, like licking honey, maybe the oozing oil was eaten, so this lair deep into the underground world was not drowned by the oozing oil.

Seeing those eating aliens, in fact, Zhang Tiancheng also wanted to find a place to live and rest and eat, and by the way, he replaced the diapers that were a little embarrassing, but unfortunately there were aliens everywhere, and from time to time along the way, he would encounter groups of aliens, and there was no place to find a place where he could safely remove his armor......

"Boom!" A loud bang swept with a violent shock wave, and the violent vibration caused a lot of caves to collapse the walls around it, and in an instant, countless aliens swarmed in the direction from which the vibration wave came.

Obviously, he was attacked by a ground-penetrating bomb, and there was more than one, and after a while, he remembered the successive explosions, and Zhang Tiancheng was also nervous, afraid that some ground-drilling bomb would hit his head.

However, this violent explosion attracted a large number of aliens away, and Zhang Tiancheng also took the opportunity to speed up his progress, relying on his keen perception, and moved backwards towards those passages where aliens constantly appeared.

The frightened Zhang Tiancheng took advantage of the chaos and quickly rolled to the side, and the few heads who were tripped by the alien sniffed suspiciously, and then turned around and quickly moved towards the place where the gunshots came from in the distance.

After stumbling and lurking forward, it lasted for nearly an hour, and finally the emperor lived up to his painstaking efforts and discovered a super-large alien lair in the depths of the ground more than six hundred meters above the ground.

In a huge pool of crude oil, tens of thousands of aliens are sucking crude oil, and their bodies are growing at a speed that is almost visible to the naked eye, and at what growth rate, it may only take four or five days to grow into an adult.

There are also mountains of alien eggs on the side, is there a small alien hatching out into the huge oil pool, indeed, as guessed, this alien has successfully evolved the ability to directly hatch a small alien to obtain nutrients from the oil no longer needs the host to provide nutrients.

The Alien Empress is not a machine with dozens of eggs, like a machine that lays eggs, dozens of eggs are produced every second, and then transported by some aliens to the vicinity of the huge crude oil pool for storage......

……

I thought that it would be smoother to quietly remove the big shield and open the lid in such an open place, take out the explosives from the passage and bury them in those cave walls, because I had tried to sneak into several other alien small nests before and were not discovered, but this time it was quite unexpectedly discovered.

As for why it's not clear, maybe it's because the alien queen's perception is stronger than that of ordinary aliens, I haven't really encountered the alien queen before, so it's not clear, but it's lucky, a large number of adult aliens were attracted by the large-scale invasion of the human army a few kilometers away, and most of the people who stayed in the cave were underage aliens, although the number was as high as tens of thousands, but it couldn't stop Zhang Tiancheng from killing the dozens of alien queens.

Holding the big shield to dodge and jump everywhere, the golden machete appears and disappears from time to time, and every time it appears, it is always accompanied by the head of an alien queen being cut off, although those alien queens are very agile and powerful, but the alien eggs in their stomachs are very slow to move, and they can't avoid Zhang Tiancheng's pursuit at all.

The price is, of course, the set of super alloy armor that is there, and the potholes are corroded by the terrible alien blood, even if the gold leaf treatment is carried out under the special plugging material of the shell, it still can't stop the highly corrosive blood of the alien empress, and even the two-meter-long gold machete has some corrosion.

However, the success of the gaga of more than thirty alien mothers, these small costs are also worth it, but this nest has not been completely destroyed, the task is still not completed, and the armor is corroded and even began to affect the ability to act, a ruthless simply unloaded the armor on his body, stuffed into the time and space channel, and at the same time pulled the rope bundles of explosives were pulled out and smashed at those eggs, and then turned around with the big shield and rushed out wildly.

It's just that I suddenly found that a few passages were completely blocked by the aliens who came back, and there was no possibility of rushing out at all, and there were a lot of aliens crawling all over the cave walls and beginning to harm themselves, and the extremely corrosive blood was like rain pouring down on it.

The body was splashed to a trace, and green smoke rose in an instant, and the true qi energy was frantically consumed, and the shield could hold on for a while, but these alien laws have been completely crazy after all the mother emperors were killed by the hateful humans, and they must pull this invading human race to their deaths......

"Damn, the plan really can't keep up with the change!" With no way out, the only way left is to enter the space-time passage to go to the Silent Hill World, and I don't know if this is considered an unauthorized departure from the mission world, but the current situation Alien has been prepared to die together, and there is no way to break through from that cave entrance.

In the end, he still activated the only remaining true qi, and his body instantly shrunk a lot, and then reversed the shield and opened the lid directly from under the hood, and instantly entered the world of Silent Hill, of course, he pressed the remote control at the moment of drilling into the world of Silent Hill.

The shock wave of the explosion even came from the space-time channel, and the person was directly washed into the air, and looked at the extremely serious corrosion on his body, and even saw the bones in several places, so he could only take out a group of spirit grass and take it down, and at the same time take out the tattered dragon cloak that was corroded and put it back on.

With the assistance of the spirit grass, the body completely recovered in the blink of an eye, and even the tattered cloak was completely recovered, and a white light directly appeared in the sky at the unified time, and the surrounding space was distorted.

This time, I just took the spirit grass and my body was at its peak, but I didn't faint because of the shuttle, and I clearly felt a time and space shuttle.

Looking at the slightly unfamiliar underground secret room, the nervous mood was completely relaxed, and finally there was no son, so he quickly opened the space backpack and found that the more than 100 kilograms of dog's head gold, seven or eight large diamonds, and the set of gold armor weighing 200 kilograms were still there.

It's just that when I saw that message reminder, I felt a little bit of pain, and I had to break into the Silent Hill world for refuge in the face of a very high risk of hanging, but it was still judged to be an unauthorized escape from the mission world, so the huge reward was gone.

However, in the end, the explosion ignited the natural gas of the cave, and then further ignited the crude oil, which in turn caused a chain reaction, and the explosion stretched for more than ten kilometers, so completely destroying the alien nest that was more than 600 meters deep underground was considered to have completed the task, so there was no additional punishment.

Of course, looking at the hundreds of kilograms of gold and several large diamonds, as well as more than a dozen very awesome scientific and technological equipment for selection, this harvest can also be regarded as unprecedented in history.
