It seems that the cause of the explosion just now, which caused the structure of the passage to be unstable, is now showing a hint of collapse.

Sure enough, it didn't take long for the passage to begin to collapse.

Fortunately, the scope of the collapse was not very wide, only a few tens of meters away, and the speed of the collapse could not catch up with them.

The good news is that the collapsing rubble has crushed most of the burst plasma bugs underneath.

Chen Mulin couldn't help but breathe a sigh of relief when he saw this scene from the radar.

But he didn't dare to let the iron pillar rest, and kept his current speed and rushed deeper.

However, the collapse didn't stop the bursting plasma bugs, which were not crushed by the rubble and poured out of the cracks.

Maybe it's the terrain advantage, or maybe it's the spider silk on the ground that makes it easier, and they move much faster than the two of them.

It didn't take long for the nearest burst plasma bug to come up and start to swell, ready to explode.

Although Chen Mulin couldn't see the situation clearly, he could guess a rough idea.

If it is shocked again, it is estimated that it will have to be explained here.

You have to find a way.

If you use the flight system, you are not so sensitive, and without the help of the Xuannu, it is estimated that you will hit the wall of the hole.

Since the plan of using the flight to escape quickly is not possible, then you can only take the initiative to attack and prevent the bursting plasma worm from approaching.

If you use a laser cannon, it is undoubtedly a knife to kill chickens, and the laser cannon will explode after hitting the target, and the efficiency is a little, but it is very likely to cause another collapse, maybe you will not be killed by the plasma worm, and you will kill yourself, and the gains outweigh the losses.

Well, now the only thing that is most practical is to use fire to burn.

But now I am facing a problem, the oxygen at this depth is still very thin, not enough to support the conditions of the fire, and even if it can be sprayed, it is only a small wisp, the kind that can be extinguished by shaking.

"That's right!"

"Oh, I'm a brain, I would have thought that I wouldn't have suffered this crime!"

If he hadn't been seriously injured now, Chen Mulin would have wanted to take off his helmet and give himself a shock.

It turned out that when building the battle armor, Chen Mulin took into account the problem of the thin atmosphere of Mars, and transformed the original flamethrower, from the original lack of oxygen supply, to the oxygen supply from the inside of the battle armor.

Coupled with the Martian oxygen storage technology, even if the flamethrower uses the internal oxygen supply of the armor, it will not cause the oxygen to be depleted too quickly.

Thinking of this, Chen Mulin didn't dare to slack off, and raised his hand to spray a flame at the plasma worm under his feet.

Effective!

Looking at the disappearing red dots on the radar, Chen Mulin hurriedly stopped the iron pillar.

Since burning with fire has an effect, why run again and toss yourself again?

"Don't run, burn them with a flamethrower!"

Hearing this, Tie Zhu stopped, and learned from Chen Mulin to aim the flamethrower at the bursting plasma worm.

Judging from the radar, those plasma bugs also seemed to be scared, and stayed where they were and did not continue to move forward.

They also have a certain amount of intelligence, although the way to attack is to sacrifice themselves to inflict damage on the enemy, but in the case of not being able to attack, they will not rush forward, but will find a way.

Seeing this situation, Chen Mulin gradually relaxed, and when he had free time, he took off the helmet, activated the oxygen mask, and then wiped the blood stains inside the helmet.

After resting for a while, and waiting for the pain to subside a little, Chen Mulin spoke: "Let's go!"

"Let's go back to the base?" Tie Zhu's idea is very simple, since he is out of danger now, and those plasma bugs are afraid of fire, then take advantage of the fact that he should return to the base now, treat Chen Mulin's internal injuries first, find his mother's affairs, and talk about it later.

Chen Mulin nodded and replied: "Yes, let's go back to the base, and then go to your mother when I recover from my injuries!"

There was no choice when it was decided to flee deeper just now, but now that there is a better situation, there is no need to go deeper, and no one knows if this internal injury will suddenly worsen.

"Okay, then where to go?" Tie Zhu looked at Chen Mulin, waiting for his decision.

"Let me see!" Chen Mulin looked at the radar, preparing to find a relatively safe passage back to the ground.

It was at this time that he discovered a surprise.

"Wait, I've decided not to go back to base yet. ”

"Why?" Iron Pillar was curious.

Chen Mulin motioned to the iron pillar: "What do you see on the radar yourself?"

Tie Zhu glanced at it, and after a while, he fell into a state of stupor on the spot.

The radar indicates that there is a humanoid creature nearly a kilometer away from here, and its vital signs are very weak, although the radar is limited, but this does not affect the fact that it can detect the creatures within the range, but it cannot show the specific location.

From this, it can be concluded that the person must have been seriously injured and was in danger of his life at any time.

This just met the physical requirements of Tiezhu's mother, who was seriously injured at the time, and after so many days, if she hadn't died, then this state was the most consistent.

That's why Chen Mulin said that he wouldn't go back, since he had found it, it was better to take it back together.

And looking at her condition, she is not very optimistic, and it is estimated that she will not be able to last long, compared to herself There are still three days, and she estimates that it will be difficult to survive even today.

At the same time, I am glad that it is fortunate that it is here today, if it is tomorrow, maybe a few days later, even if it is found, it will be a cold corpse.

After a long time, Tie Zhu jumped up excitedly: "Found it, finally found my mother!"

"Yes, I found it!" Seeing Tie Zhu's happy appearance, Chen Mulin's mood was also a lot happier.

Seeing the iron pillar, he was almost happy, and Chen Mulin said: "Don't be happy too early, I don't know your mother's specific location yet, and you also see that her condition is not very optimistic." ”

"But you don't have to worry, since the radar can detect it, then your mother should be within a thousand meters, and it shouldn't be too difficult to find. ”

"You stay here first, don't let those bugs crawl over, give me a little time, and I'll find where your mother is." ”

"Well, I'm sure you'll find it!" The sudden good news made the iron pillar dilute the fear in his heart, and he couldn't see the fear on his face when he was dealing with the plasma bug alone.

Seeing this, Chen Mulin also put his mind at ease, sat down on the spot, and began to look for the location of the humanoid creature.

Yes, due to various limitations, the radar can only scan the biological dynamics at a distance of a few hundred meters, and any further ones can only be slightly reminded and cannot be detected directly.

But things are not absolute, and without the help of the base, it is not impossible to carry out long-range detection, such as changing the pattern to a straight line.

Yes, as long as you change the detection mode to a straight line, you can detect the dynamics of creatures within a kilometer, and it will not increase the amount of computation of the warframe.

The only drawback is that it can only detect one direction, and it can't detect the surroundings in real time, so it's okay to find people, but it's very dangerous to use in ordinary times, and you can't find creatures in other locations in advance.

What Chen Mulin has to do now is to sweep it at 360 degrees, designate a good route after finding the target, and strive to rescue it in a short time.
