Tie Zhu and Chen Mulin walked side by side, constantly looking around: "Dad, what kind of place is this, I'm a little scared!"

After all, he is not very old, he is equivalent to a teenager on Earth, and his previous memories are gone, so it is normal to be afraid of these dark and narrow passages.

Chen Mulin comforted: "Don't be afraid, it's just an ordinary tunnel, as long as you don't encounter strange beasts, there is not much danger." ”

In fact, let alone an iron pillar, Chen Mulin was also a little worried, several underground experiences made him know the hidden crisis here, although the biggest danger came from the alien beast, but it was not certain that this was absolute.

For example, the cockroach excrement I stepped on last time, just the excrement has a strong corrosive ability, who knows if it will catch fire?

Thinking about it again, this is the territory of plasma worms, maybe their feces still have the ability to paralyze, and it should be themselves who should be afraid, after all, they don't have a strong physique.

But it can't be helped, who makes themselves older.

"But, I'm still afraid!" Tie Zhu did not become bold because of Chen Mulin's words, he still couldn't control the fear in his heart, took Chen Mulin's hand, and moved forward very slowly.

Chen Mulin stopped, looked at Tie Zhu and said helplessly: "In this way, let's open the barrier, you follow me, and I'll explore the way!"

"Okay, okay, I see!" Tie Zhu nodded, opened the barrier, and consciously retreated to the back, just sticking to Chen Mulin's back, not daring to go too far, and glancing behind him from time to time.

Chen Mulin froze, looked at the radar and continued to move forward.

Gradually, the depth came to about two thousand meters, and there was no incident all the way, without encountering any emergencies.

Thanks to the bioradar, Chen Mulin was able to bypass the place where the alien beasts gathered.

It's just that he is still very uncomfortable, too aggrieved, because the bioradar is affected, the detection distance is too small, so the travel speed is unusually slow.

There is no way to do this, and this situation may not be improved until it reaches about 5,000 meters underground.

But this is also just a guess, there may be plenty of oxygen underneath, but there may not be energy crystals.

If not, the signal will continue to be limited, and it will be equally difficult without the help of the base equipment.

At present, it can only be like this, what Chen Mulin wants now is to help Tie Zhu find his mother first, and then find an excuse to return to the base after figuring out this place.

He knew in his heart that it was too difficult to find someone here, although it was not as good as the needle in the sea, but it was not far off, after all, there were still a bunch of fierce beasts here.

Just when he went down to about three thousand meters, Chen Mulin finally discovered something unusual.

"Iron Pillar, what do you think it is?"

In the distance, Chen Mulin saw a filamentous object, covering the cave wall, and there was a large group of small creatures crawling around on it, and he didn't know what it was.

Since there are still a lot of small creatures underground, because they do not pose a threat and will affect the sensitivity of the radar, Chen Mulin shielded some smaller creatures on the radar, and it is normal that he failed to detect these creatures in advance.

Chen Mulin's sudden opening startled Tie Zhu slightly, and after he came to his senses, he glanced in the direction that Chen Mulin was pointing: "It looks like a little spider." ”

"I think so too!" Chen Mulin nodded and plucked up his courage: "Let's go, go and see!"

"No, I don't want to go over!" Tie Zhu pulled Chen Mulin, with a look of fear in his eyes, and Chen Mulin couldn't leave no matter how he dragged him.

Helplessly, Chen Mulin began to reassure: "Direction, according to my experience during this period of time, the smaller the size of the alien beast here, the weaker the attack power. ”

He pointed to the little spiders crawling around and said, "As far as those tadpoles are the size and size, they are not even a threat, and they can trample a large group of people to death with one foot." ”

Tiezhu finally relaxed: "That, okay then!"

That's it, Chen Mulin walked over with the iron pillar.

The closer he got, the more Chen Mulin gradually saw the appearance of the creatures.

"Sure enough, it's a spider!"

"Looks like this is the spider's lair!"

Walking to the little spider, Chen Mulin squatted down, very curious, wanting to see what was the difference between the spider on Mars and the spider on Earth.

After taking a closer look, Chen Mulin muttered, "No, this thing can't be the larvae of plasma worms, right?"

"Tiezhu, come and see, do you want to be a little plasma worm?" Chen Mulin looked back at Tiezhu, but found that he had been hiding behind him, and he didn't dare to look at it.

Chen Mulin scolded with a smile: "What's there to be afraid of, it's all too big, and you're still afraid of the small ones?"

Tie Zhu still kept shaking his head, but he didn't look at it.

Suddenly, Chen Mulin thought of a symptom, claustrophobia, maybe Tiezhu is claustrophobia, in this environment, his heart will be greatly impacted, if it is not for a belief in his heart, maybe he will not follow in.

With that, Chen Mulin shook his head and began to study these insects on his own.

The more he looked closely, the more certain he was that this was the larva of the plasma worm.

Similarly, the abdomen glows blue and the shape is similar, the only difference is that the bodies of these bugs are translucent.

But this does not deny that they are not plasma worms, after all, they are larvae, and translucency is very common.

If it's really plasma worm larvae, then this is not the territory of spiders, but the territory of plasma worms.

Think about it, there is plasma insect activity on the ground above here, which is only a few thousand meters, and even the cockroach's nest has a large space five thousand meters below, and the territory of plasma insects cannot be such a small area.

Based on this speculation, it is impossible to find the Martian habitat in this area, which is the territory of the plasma worm.

Now that you have the answer in mind, there's no point in continuing to explore.

But looking at the iron pillar, Chen Mulin felt that he still had to explore deeper, and it was good to go through the motions, just carefully avoid the plasma worms to ensure that he could return safely.

Thinking of this, Chen Mulin began to greet Tiezhu: "Let's go, the next road is estimated to be dangerous, let's be careful!"

"Uh-huh!" Tiezhu nodded, eager to move forward.

For him, although he has a claustrophobia, it is much better to keep moving forward than to stop.

If you stop, you will feel trapped in the dark, but when you walk, you will feel that you are looking for a way out, and you will give yourself a psychological comfort.

This is not the most important thing, the important thing is that when you walk, you will be affected by the process of finding your mother, so as to dilute the fear in your heart.

Nodding at the iron pillar, Chen Mulin took the lead in stepping over the group of small plasma worms and continued to move forward with the iron pillar.

However, they still accidentally touched the spider silk.
