I tried again, but the engine was still in a failed state.

Chen Mulin shook his head helplessly: "It seems that things can't be recovered in a short period of time!"

He took out the kettle and shook it, and there was silence for a moment.

"You really can't just sit still!"

"It's time to act!"

After thinking about it last night, he made a bold decision.

That is, if the engine hasn't been restored today, take the risk to explore this underground world.

This is also a helpless move, even if those cockroaches do not come back, they will face the problem of not having water and food.

Since there are living things in this underground world, it is impossible to be without water and a source of food.

If you do this, you might as well explore, maybe you can find drinking water and food in the next space, and then survive first, and when the engine is restored, then come back here.

As for the vehicles outside, there is no need to worry about the protection of the defense system at all, as long as the energy crystals are not consumed, the vehicles and equipment are safe.

Anyway, now that I have a map of the underground passage, it won't be difficult to return here, and I won't get lost underground.

As for the eight drones, let them continue to move forward, and one day, they may be able to calculate the entire structure of the underground space, so that the chances of spotting Martians will also increase.

made a decision, and Chen Mulin switched the live camera back.

"Brothers, come back to your senses!"

"That's right, my flight system has failed, it's not clear when it will be back in use, I don't have food now, and I only have just over a liter of water left, and if I continue to consume it like this, I will definitely die!"

"After careful consideration last night, I decided to go to this underground space and explore this mysterious world, since there are creatures here, there is definitely water for so long, this is my only hope to live!"

"But don't worry, except for the flight system, all the functions of this suit are normal, there are endless energy crystals here, and there is no need to worry about energy problems, and there is plenty of air, the temperature is stable at about twenty degrees day and night, as long as I can find food and water, it is not a problem to survive, and when the engine is restored, I will be able to return here through the map, and return to the surface and return to the base." ”

[Barrage: The summary is very detailed, according to me, it should have been like this a long time ago, life is full of infinite hope, good luck!]

[Barrage: I'm about to vomit, won't we be asked to count the rice grains next time?]

[Barrage: It's good, it's good, I also support doing this, but there's a problem, don't keep letting us count the rice, okay?]

[Barrage: Pretend to compare once, and then let me count the rice, and I'll take it off, do you believe it?]

[Barrage: Good luck, we support you spiritually!]

......

"Okay, my, I shouldn't have asked you to count the rice, not next time!"

Chen Mulin apologized very sincerely, but in his heart, he was thinking about whether he should let them count the rice grains next time, to be honest, this is not difficult for Chen Mulin, as long as the lens in the farm is adjusted slightly.

Of course, this is just to think about it, he still has a good conscience, and it is just a helpless move to let them count the rice, so they should be quiet.

"Alright, without further ado, let's go now!"

Chen Mulin glanced at the map, randomly picked a space that seemed more likely to find a water source, and found the right direction and plunged into the passage.

Chen Mulin didn't have any expectations for the distance of the first kilometer, he had seen it through the lens of the drone, in fact, there was nothing special about it, it was just an ordinary passage, and the rock wall was inlaid with energy crystals.

It was also because of these energy crystals that Chen Mulin's signal could be maintained, otherwise he would not dare to explore rashly.

Walking to the site of a collapse, Chen Mulin pointed the camera at where.

"You see, this landslide was originally a passage to the ground, that is, a passage for those cockroaches to get out, and the collapse was caused by the shock wave of the explosion, and almost half of the passage collapsed, and it was impossible to dig through it. ”

According to the three-dimensional map owned by Chen Mulin, there are indeed passages to the ground above here, and there are dozens of the same passages, but they have all collapsed.

Because this place is the closest, it is the most complete collapse, the 4,500-meter passage has collapsed by almost half, and the rest of the slightest has also collapsed hundreds of meters, there is no way to dig it up, and hard digging may also cause a secondary collapse.

After a little glance, Chen Mulin continued to move forward.

It took Chen Mulin five minutes to walk the distance of the first kilometer, and he did not encounter any danger on the way, nor did he encounter any other creatures, perhaps because this is the territory of cockroaches.

"It's not far away where the drone loses its picture, I have to hurry up and see what caused it, explain in advance, I may lose the picture later, but don't worry, I will broadcast the whole voice broadcast for you, it will definitely not be boring!"

There were still a few hundred meters away, Chen Mulin quickened his pace and trotted over.

In the distance, a disgusting scene came into view.

"Hey, it's disgusting! This can't be cockroach snot, right?"

Chen Mulin stepped forward and looked at it with disgust, not daring to get too close.

Yes, the walls of the cave are covered with green slime, forming a film that blocks the way.

There is no doubt that this is arranged by the cockroaches, and the rear is their territory, and it is normal to use it to protect the territory.

Now that I finally know why the drone lost its footage, it's no wonder that it's green when it's covered with a layer of slime.

Fortunately, Chen Mulin is prepared, and those things manufactured behind have anti-corrosion coatings, otherwise the drones will have to be scrapped.

If you want to move on, you have to go through this green film, which is unacceptable and disgusting!

"It looks like the only way to move forward is to burn him with fire!"

Chen Mulin raised his hands, and the mechanical arm opened a hole, revealing two spouts, and flames erupted with it.

The flame burns with green slime, making a sizzling sound, and the burned slime releases a thick puff of black smoke?

It was a toxic gas, but fortunately, Chen Mulin was still wearing a helmet, otherwise he would have fainted to death.

Soon, all the slime was burned up, and only a dark trail remained in the distance.

"That's it!"

"Let's move on, be careful!"

If you have this distance, you are leaving the territory of the cockroach, and perhaps the cockroach territory is also dangerous, but other places are unknown, and you may encounter more dangerous creatures.

Maybe the next one is the territory of the big spider, or the territory of the big lizard, and there may be some unknown substances that are harmful to the human body.

All in all, the trip won't be too easy.
