Oh, no! I think it's all sorts of 360 degrees to sweep this area.

This difficulty, to be honest, is a bit big,

For example, it is very simple to hold a long stick and turn it in parallel, but it is very difficult to turn it in all directions, and it is still airtight.

If you're lucky, you'll find it in a circle, but if you're unlucky, you won't be able to find it in half a day.

Fortunately, there is now a clear direction, and it is certain that the signs of life must have come from a deeper depth, and only at that depth can there be enough oxygen.

She definitely didn't have time to bring supplies with her when she fled, and the oxygen mask was so big, if she didn't find a place with oxygen, she would definitely not be able to hold it for so long.

Similarly, now that they are located more than 2,000 meters underground, the detection distance will be reduced by half, and the detection area will be greatly expanded after being reduced by half.

With a clear direction, now Chen Mulin only needs to stir it down like a-stirring stick.

"Found it!"

Fortunately, half an hour later, Chen Mulin finally discovered the location of the humanoid creature.

Sure enough, it was about five thousand meters underground.

"Found it?" Iron Pillar leaned over and said eagerly, "Where is it?"

Chen Mulin shared the detection data on the iron pillar's armor and said, "It's not very far from here, if nothing else, the route we took is the same as that of your mother." ”

"Then let's go down quickly!" Iron Pillar jumped again, as if he had forgotten what he was doing.

Chen Mulin hurriedly reminded him: "You pay attention, the bursting plasma bug is going to be scared!"

"I'm sorry, I forgot!" Iron Pillar bowed his head apologetically, turning around to continue to stop the Bursting Plasma Worm from advancing.

"It's okay, it's good that you didn't come over!" Chen Mulin breathed a sigh of relief, and then continued: "You wait, I'll study the route first, so as to save me from making mistakes again." ”

After nearly half an hour, Chen Mulin was still sitting on the ground and had no intention of leaving.

Tie Zhu looked in a hurry, it had been almost an hour in total, and he had been breathing fire all the time, and if he continued like this, he was afraid that the oxygen would be consumed.

Although he still had an oxygen mask as a backup, Tie Zhu couldn't help but smile and asked, "Isn't it okay?" My armor only has 30% of the oxygen reserves left, and it can continue to breathe fire for half an hour at most. ”

"Come on, give me another five minutes!" Chen Mulin replied, and then continued to study the route.

There is no way to do this, after suffering an internal injury, you have to be careful with every step in the future, plus there is another injured person below, you must study the route well, so as to ensure that nothing goes wrong.

If you go straight ahead, you may be able to get there, but you will inevitably take a lot of detours.

What Chen Mulin has to do is to continue to probe downward, and then calculate two routes and draw them, one for use and one for standby.

About 80 percent of the calculations have been calculated, and it will not be long before the entire route will be drawn.

Five minutes later, Chen Mulin stood up and shared the drawn route with Tiezhu: "It's done, let's go!"

The run continued again, but unlike last time, they had a clear direction this time.

And Chen Mulin also noticed that after burning the spider silk, the crawling speed of those plasma worms would become very slow.

He was pleasantly surprised by this discovery, and after burning the silk for a distance, they managed to shake off the pursuit of the bursting plasma worm, so that they didn't need to continue running, they just needed to take a bigger stride.

"Ahem, cough, ahem!" As soon as he stopped running, Chen Mulin coughed violently and coughed up a lot of blood again.

Tie Zhu stopped and asked with concern, "Dad, are you okay?"

As he spoke, he took out his kettle and handed it to Chen Mulin.

"No need, I'm fine!" Chen Mulin waved his hand: "It's just that I ran too hard just now, just take a little rest!"

"Then let's rest for a few minutes!" Tie Zhu helped Chen Mulin find a rock to sit on, and at the same time he also took off his helmet and drank water.

To be honest, because of his strong physique, he doesn't feel a trace of fatigue now.

I really wanted to continue on the road, but looking at the cheap father in front of him who was injured for himself, he could only wait.

After a few minutes, Chen Mulin's cough subsided slightly, and looking at the anxious iron pillar, he stood up: "Rest, let's continue walking!"

Tie Zhu was still a little uneasy about Chen Mulin's situation: "Either take a rest for a while, right?"

Chen Mulin shook his head: "No, I've rested enough, besides, your mother is more injured than me, I can support it for a few days, and he may not be able to last even a day." ”

"Then, okay!" Tie Zhu thought about it and felt that it made sense, so he helped Chen Mulin to walk down the route.

During this period, Chen Mulin said several times that he was fine and did not need the support of the iron pillar, but he was rejected by the iron pillar, so Chen Mulin had to give up and let him support him to move forward.

All the way was uneventful, and they used the backup route of the main route to skillfully dodge the large and small plasma bugs, and successfully reached the location of the target.

"Here it is!"

Chen Mulin stopped and looked at the radar, and now the distance can find her location without changing the transmitter detection mode, just a few meters in front of her.

"Look for it, it's dangerous here, there are a lot of plasma bugs around. ”

Hearing this, Tie Zhu walked over, this was a multi-channel fork, he turned around there several times, came back and shook his head and said anxiously: "No!"

"How is it possible?" Chen Mulin looked at the radar again to confirm the location: "That's right, the radar station display is in front." ”

He walked over in confusion and looked for it himself, not to mention people, not even a plasma worm.

"It's so weird, is it possible that she will still run away?"

"Could it be that there is a problem with the radar?"

Chen Mulin looked at the iron pillar, but he shook his head and said that the location shown by his radar was also here.

"Since there's no problem with the radar, could it be that she's really here?"

Puzzled, Chen Mulin stretched out his hand and patted the rock wall.

Just such a shot really made him see the difference.

Just like that, the rock wall was concave, and then a layer of skin fell off.

"Disguise?"

Before Chen Mulin was surprised, he found that behind the disguise was a hole, and in the hole lay a Martian, who was the mother of the iron pillar.

Chen Mulin beckoned: "Come here, your mother is here!"

really found it, Chen Mulin couldn't believe that he had really found Tiezhu's mother.

Importantly, she is alive.

Looking at her dying, Chen Mulin felt a kind of sadness, and remembered the scene of the first meeting.

Seven children, six died instantly, only one survived, and also had amnesia, what a blow for a mother.

If there is not a glimmer of hope, it is estimated that she will fight with the plasma worm, and it is estimated that she will not live until now, and her only hope is the iron pillar.
