The giant flying saucer finally flew to an altitude of 100,000 meters above the crater and hovered still, as if waiting for the group of flying saucers below, and as if it was on alert, using its powerful detection system to find intruders.

Of course, the giant flying saucer was parked at an altitude of 100,000 meters, and Erdan could not see it with the naked eye, and what he could see was almost a hundred or so small flying saucers that were "lai" in the volcanic cave.

More than 100 flying saucers were scattered and flew back and forth in the cavern with a diameter of 80 kilometers, as if looking for something. The flying action of the flying saucer is very vigorous and fast, even the complex of helicopters and fighters on our planet is not comparable to it. They can stand their flat disc body up 90 degrees and fly up and down, backward and left, and at various angles. Basically, we can think of any flight posture, it can do.

Flying saucers, flying saucers, what do you mean by not leaving in the volcanic cave? Show off your driving skills? Having a flying skills competition? Like Mount Olympus to make a final goodbye? Or are you really looking for an intruder?

Huh, intruder? Are there invaders on Mars?

Yes, it has to be! For example, Comrade Li Erdan, a visitor from the "alien planet".

Erdan's heart couldn't help but raise his throat, and he was very worried that these flying saucers were looking for him and Alice.

But isn't it, just now Erdan threw a stone into the crater, and he was cheeky and sang loudly, and when he was tossing on the top of the volcano, it was so loud that it was impossible for the Martians to find him. If it is discovered, it is to be characterized as an intruder. For the invaders, it is strange that they are not destroyed.

After the Martian saucer swarm flew out, the beam of light from the bottom of the volcano suddenly faded, and the hole below seemed to be closing.

Alice had to use her divine sense to remind Erdan, "Brother, hurry back to the flying saucer, it's not appropriate to stay here for a long time, we have to leave." ”

With a whoosh, Erdan flew out, not towards the flying saucer, but at the pillar of light, responding: "The flying saucer is in your charge, don't use weapons until you have to." I went to the bottom of the crater to see what was going on. ”

I have to admit that Erdan is now becoming more and more curious about aliens. He was curious to know the question, how many aliens are there on Earth right now? Where are they sneaking up on Earth? What the hell are you going to do? ……

Alice recognized a disobedient master with such a personality, it was really unlucky, and it was possible to put herself in it. But she couldn't help but listen to the words of the second egg's master, so she could only get angry. At this moment, there was no pretty figure of her in the flying saucer, because the power of her brain's mind turned into a beam, tightly surrounding the left and right of Erdan.

The words are divided into two ends. The Kukulkan UFO is hiding in a large crack in the inner wall of the crater, blocked by rocks, and it is still in a stealthy state, and the "Martians" will not be able to detect it for a while and a half.

Erdan's Yang God flew unscrupulously to the crater shrouded by the pillar of light in a stealthy state, and condescendingly, he saw a scene that he would never forget. At the bottom of the volcano at a depth of 10,000 meters, a huge "door" is closing, and the light is shining from this "door", bright white as a laser. This door is also very special, it is not the door that we usually use that rotates around the pin, but a kind of mechanism door that shrinks from the periphery to the center, and N parts are embedded together, like a transformer, which can be large or small. The Underworld Eggs inside the door couldn't be seen because the light was too bright, although the light was getting weaker as the door closed.

The maximum diameter of the flying saucer that flew out first was 500 meters, so the door at the bottom of the volcano must be greater than 500 meters, and the second egg was 1,000 meters in sight, which was exactly the diameter of the pillar of light. Although 1,000 meters is very large, it is much smaller than the 80,000-kilometer crater, and even if the crater gets smaller and smaller the further you go, the area at the bottom is several kilometers.

And above the "door", how can there be so many volcanic rocks? In this case, the "door" is closed, and even if someone goes down to the bottom of the volcano, he will not be able to find his deposit. This can completely explain the fact that we find light coming out of the caves on the earth, and people can't find the source of the light after entering it. If the rock of the cave could open and close, glow when opened, and return to its original state when it was closed, who would be able to find out.

Even if the sun is directly above the crater, it cannot illuminate the bottom of the volcano at a depth of 10,000 meters, so it is in a state of darkness all year round, unless the doors of the underground world are opened.

It's all here, so why not take a stroll inside before the door closes? Anyway, I can penetrate the wall, even if the door of the underground world is three meters thick metal, I can still pass through.

Just do it when you think of it, the second egg who is not afraid of heaven and earth has always been like this. His body was upside down, his head down, his legs up, and his posture was so handsome, that he flew towards the gate of the underground world that was about to close.

One qiē will be revealed after the second egg enters the underworld.

The "underground" world, a mysterious place, often appears in film and television literary works, and it is rendered so well that viewers yearn for it. Before entering the underground world, a scene had already appeared in Erdan's mind: a psychedelic city, gorgeous light and shadow, high-rise buildings, wide roads, all kinds of vehicles speeding on the road, flying saucers scurrying in the air, and Yan zhòng's deformed "humans", extinct animals and plants,......

Last time in Beijing, the Underground Civilization Exploration Center, when Erdan went to the "General's Banquet", he met a professor named Wang Zhi from the Department of Geophysics of Beijing University, Professor Wang Zhi is a loyal fan of the "Earth Hollowness Theory".

Could there be an underground world hidden inside the earth?

It is quite possible alas! I haven't seen it again, who the fuck knows.

The depth of more than 4,000 meters is enough for the second egg to fly for a while. But just as he was complacent about his stealth skills, a Martian flying saucer spotted him and flew towards him many times faster than him, all the same time various weapon systems in place, such as a laser cannon aimed at him.

Although the second egg is invisible, it is not "traceless". The volcanic dust in his path changed, meaning that he stirred the currents. This clue is enough for the UFO's keen detection system to detect the anomaly. Moreover, the UFO's super electronic computer can also sketch a humanoid shape that looks like two eggs according to the number jù transmitted back by the detection system. Of course, the Martians may have other magic weapons, which can detect stealth objects, after all, their technology is not generally advanced, and even advanced to the point that we can't even think of it with our heads.

At this moment, Li Erdan was pouting and flying to the bottom of the volcano, not noticing that he had been detected by the Martian flying saucer.
