The huge sinkhole was pitch black, especially in the diverted magma, which was full of weirdness. Pen, fun, and www.biquge.info

Even the most well-trained and experienced explorers would not easily enter such a cave. Chi Jia and the others reported their findings, and on the one hand, they sent drones into the sinkhole cave for further reconnaissance, and on the other hand, they continued to advance along the Mariner Valley, and landed on the plateau in the middle of the Mariner Valley.

The team members dressed in individual armor walked out of the landing ship one after another, and the first to step on the Martian ground was naturally the captain Chi Jia.

Because the gravity is smaller than that on the earth, even with the adjustment effect of individual armor, the expedition members still feel that their actions are too easy, and they can jump dozens of meters away with a slight jump, which is still the situation that they have not opened the strength of individual armor.

Some samples were taken and a few photos similar to those of tourists were taken, but the thoughts of the team members were not here, and the huge sinkhole cave became a big mystery in everyone's minds.

Even Tashvi, who was most excited about arriving on Mars, was not interested at all at the moment, and said to Huang Quan naggingly: "There must be something under that big hole, otherwise it is impossible to separate even the magma." ”

Huang Quan shoveled away a stone with a tool, and actually saw a blue light inside, it was a very beautiful sapphire, Huang Quan smiled and put the gem in his pocket, and said: "Okay, don't think about it, no matter what you find down there, it has nothing to do with us." ”

Tashvi shouted: "How can it not be related to us? That's what we found. ”

Huang Quan said sarcastically: "Do you think you can still share the benefits for us?" Not to mention that we just saw the sinkhole, such a discovery is not enough to provide us with any benefits, maybe you can name the sinkhole cave. ”

"Yes, yes, even if it's a name."

The peculiar sinkhole cave on Mars also attracted Bai Zhongqi's attention at the first time. The drones sent by Chi Jia and other expedition members are not responsible for controlling and monitoring themselves, and they have their own special personnel to deal with them, and Bai Zhongqi is also quietly in Ruyi City, watching the pictures sent back by the drones.

The sinkhole cave is not only large in diameter, dozens of kilometers in size, but its depth is obviously somewhat unexpected.

Bai Zhongqi squatted in front of the surveillance screen, pinching his beardless chin, and thought, "This big hole won't lead all the way to the center of the earth." ”

Not long ago, the matter of Cui Haixing has already made Bai Zhongqi have a shadow on the center of the earth. Although the planetary life of the Emerald Starfish is in a state of consciousness chaos, if it is not for special detection methods, it will not know what difference it is from normal planets. But not knowing that the planetary life that was born hundreds of millions of years ago and has terrifying power made Bai Zhongqi full of vigilance about anything that the Iridium people did not understand.

When playing the game, Bai Zhongqi was happy to see any unexpected situation, even if it might catch him off guard, forcing him to load the archive and start again. But in reality, every unexpected discovery made Bai Zhongqi nervous.

It's a pity that this is the universe, a place of infinite possibilities. Even if the Iridium United Empire is so powerful, it will still capsize in some gutter, and if Bai Zhongqi, as the head of state, makes a major mistake, it may even make this empire doomed.

Dozens of dragonfly drones suddenly entered an open place after going deep into the sinkhole cave for tens of thousands of meters, and at the same time, the body of the drone suddenly became extremely inflexible.

Bai Zhongqi's eyes narrowed, and he quickly found the reason. The dragonflies' sensors show that they are in an environment of only 1.5 Earth's atmospheres.

The atmospheric pressure of Mars itself is lower than that of Earth, and the pressure on the drone will continue to increase as it enters the sinkhole and goes deeper and deeper. But for some reason, after suddenly entering this open field, the atmospheric pressure actually changed drastically.

"These ......"

Bai Zhongqi had already seen the surrounding environment through the dragonfly's camera at this time. He jerked up from his seat, his eyes shining.

"It's a man-made ecosystem." Mo Laitong, the director of the Imperial Research Academy, who was also looking at the surveillance images, recognized all this at a glance.

More pictures were passed on, so that the hologram in front of Bai Zhongqi could present him with a more complete picture of the pattern. In the picture, several dragonfly drones are flying high in the sky, as if hovering among the clouds. The entire zenith is full of blue sky and white clouds, which is very similar to all the blue sky and white clouds in Ruyi City.

Relying on spectral scanning, the drones were able to discover that directly above them was the big hole they flew down. But the man-made biome system here obscures the big hole, and while it won't be a problem to pass, it looks like it doesn't exist.

From the fake zenith to the "ground", the distance is about 800 kilometers, such as the artificial ecosphere of Yicheng, which is much larger.

Mo Laitong was checking all the detection data sent back by the dragonflies, and said: "The fake star hanging on the zenith is really glowing, so this man-made biosphere system must still be maintaining normally, and it is more realistic than the biosphere system of our Ruyi City." ”

Bai Zhongqi watched this amazing scene, silent, and the first question that came into his mind was, why does there exist such a huge man-made ecosystem under Mars?

The environment here was clearly built to suit the living habits of the primates, and there are various races in the galaxy that tend to prefer different environments. Some races prefer oxygen-rich environments, while others prefer more sulfide or nitride in the air. Some tend to have a carbon-dioxide-rich atmosphere, while non-carbon-based animals are even more diverse.

Bai Zhongqi made a quick decision and sent more reconnaissance vehicles into the sinkhole. It took him nearly a day to finally get a rough idea of the scope of the man-made ecosystem under this huge sinkhole.

This underground man-made ecosystem covers an area of more than 40 million square kilometers, with complete topography, landforms, rivers and lakes. Unlike the man-made biosphere built by the Iridium, there is no life here, there is soil on the ground, but there is no vegetation, let alone animals. Even in the sampled soil, no microorganisms were found, but it was filled with organic matter.

And in this empty underground world, a huge building that leads from the "ground" to the "sky", that is to say, a height of 800 kilometers, stands in the middle of the man-made biosphere underground.

This obvious man-made building should be the main control platform of the underground man-made ecosystem. It's just that this building, which is like the Tower of Babel, is somewhat similar in shape to the Mayan pyramids, with a square base, and the upper layer is another square formed by the four midpoints connected by the midpoints, and the upper layer is a square formed by the midpoint connecting lines, and the cycle repeats itself until the highest point.

This huge building full of mystery made Bai Zhongqi first think of words like "temple" or "altar". There is no doubt that the building is of a very high level of technology and is able to sustain a man-made ecosystem of more than 40 million square kilometers.
