The more he dug down, the more the area of the energy crystal was exposed, the more surprised Chen Mulin became, and he unconsciously opened his mouth wide.

"Oh my God, such a big piece!"

Now the physical strength just dug out has exceeded his estimates.

Chen Mulin couldn't help but speed up the excavation, and finally the volume of this energy crystal was determined, with a diameter of about three meters, just enough to pass through the passage above.

It's a round energy crystal.

"It's time to test the strength of Krypton One!"

Chen Mulin hugged the energy crystal with both hands, trying to move it out in one fell swoop.

Maximum power output!

"Up!"

With Chen Mulin's loud shout, Ma Krypton No. 1 began to exert his strength.

After a little stalemate, the energy crystal rose from the ground and was picked up by Chen Mulin.

Almost step by step, Chen Mulin placed the energy crystal under the passage.

Looking back, he saw that there was a passage beneath the pit of the energy crystal.

"What's going on?"

"Brothers, I found out that there can be a passage!"

Chen Mulin immediately walked over to check.

However, the searchlight did not reach the bottom, and it was pitch black below, like a bottomless abyss.

Then, he noticed that the oxygen level in the place had actually begun to rise.

"Is it ......?"

After thinking for a moment, Chen Mulin suddenly became excited.

He had been speculating that there was an extremely oxygen-rich underworld underground, and that the oxygen content had begun to rise when the passage was dug up.

This is enough to prove that the guess was correct.

Although it is not certain whether the end of the passage is the world inhabited by Martians, there is definitely enough oxygen in it to survive.

In any case, this is a clue that must not be let go, and now that the equipment level has gradually risen, he is confident that he will make a safe trip.

He decided to go down and find out.

However, before going down, all the energy crystals must be transported out to facilitate the next action.

Chen Mulin first climbed up to the passage, took a chain, hoisted the energy crystals up, and returned again after loading all the energy crystals onto the transport truck.

Now at the entrance of the passage, Chen Mulin did not rush down, but greeted the sailors first.

Because he didn't have the budget to go deeper underground, the signal repeater he prepared had been used up, and eighty percent of the signal would be interrupted after entering, so give them a preventive shot first.

"Let me remind you, the signal may be interrupted after entering this channel, I have set up the signal to interrupt the live broadcast room and the camera will be automatically switched, you must be prepared to count the rice seedlings. ”

[Barrage: I'm against it!]

[Barrage: Strongly protest, go back and get a few more repeaters.] 】

[Barrage: Oppose plus 1, protest plus 1......]

"Opposition is invalid, protest is invalid!"

Chen Mulin ignored them, didn't make any preparations, and jumped down directly at the passage.

The descent went faster and faster, and the depth went from 500 meters to 1,000 meters, then 2,000 meters, then 3,000 meters...... It wasn't until it was close to five thousand meters that a wave of air erupted from the soles of Chen Mulin's feet and stopped steadily, and the depth at this time just came to five thousand meters.

Just as Chen Mulin thought, when it was about a thousand meters, the signal was interrupted.

As he thought, it was filled with enough oxygen to survive, the amount of oxygen on Earth, perfect for living things.

He didn't rush to turn on the searchlight, the first thing Chen Mulin did after landing was to check the bioradar, wanting to detect the location of the creatures here, and prepare for a preemptive strike while the creatures here had not yet discovered their whereabouts.

"Bugs, where are you, Daddy!"

As the radar scanned, red dots began to appear on the screen, quite a few of them, scattered all around, leaving a large gap in the middle, and there was only one red dot in the center of the gap, which looked like a pilgrimage.

"Why is this happening?"

Chen Mulin touched his chin and muttered to himself, thinking about it.

Like pilgrimage, this situation is not only found in human society, but is common throughout the biological world, even plants.

It's like a giant tree, there are definitely no tall trees around it, at most some shrubs and other vegetation, or vines.

It's like a wolf pack, when the wolf king is eating, other wolves don't dare to approach at will.

Suddenly, a trace of uneasiness rose in Chen Mulin's heart.

"Could it be...... This is the nest of the big cockroaches?"

The more you think about it, the more likely it is that if it is the territory of the Martians, it will definitely not be so dark here.

Why, because it can be seen from the lighting of the tent that the Martians also need light.

The only thing left is the speculation of the cockroach nest, after all, such a large group of cockroaches cannot be ruled without a king.

Of course, the possibility of other creatures is not ruled out, but these possibilities are not as high as the probability of cockroach nests.

When Chen Mulin was thinking, he found that those red dots actually moved, and they were approaching in his direction.

"Oops, found out!"

Chen Mulin's heart immediately lifted.

Do you want to run?

Maybe they're just moving around casually, just by chance.

However, those red dots didn't give Chen Mulin much time to think, they began to speed up and get closer, and they were still swarming.

"Damn, it's really coming at me, are these big insects so smart?"

Chen Mulin didn't dare to stay any longer, and hurriedly started the flight system.

The moment he took off again, he turned on all the searchlights, just such a rare opportunity, it's a pity not to see what the cockroach king looks like, he can't waste such an opportunity, how can he let the equipment shoot it.

As the searchlight turned on, a behemoth revealed itself under the illumination of the light.

"I'll go, it's a monster!"

Chen Mulin's jaw was about to hit the bottom of the helmet.

The big cockroach looks the same as other cockroaches, and in addition to its particularly fat belly, its body size is countless times larger than other cockroaches, just like the little monster in Ultraman.

There is no doubt that this thing can kick a building with one kick.

Besides, that's a huge army of cockroaches.

The people who can stay next to the king must not be some good stubble, just take the one that rushes to the front, for example, the physique is the size of a truck.

This is nothing, in addition to the cockroach king, Chen Mulin also found several small western-style buildings in the rear of the cockroach colony.

If it is said that the one who rushed to the front is only the cockroach general, then the next few are the princes, who are definitely the absolute overlords under the cockroach king.

At the same time, Chen Mulin found that this space is also extremely huge, and it is initially estimated that the land area of at least one small town is indispensable, with a radius of dozens of kilometers.

According to normal circumstances, it is impossible for Chen Mulin to estimate the area of this place by relying on searchlights alone, but it is full of crystals that can reflect light, and when it is illuminated, the entire space is brightened up by one point.

Those crystals are all energy crystals!

Especially the one under the cockroach king, at least the size of a building, it is really greedy to look at.

In this instant, the entire space was in full view, and the next moment Chen Mulin rose to the sky and flew up along the passage, whether it was a huge energy crystal or a cockroach king, everything was in vain.
