Through the night vision device, after the color imaging processing, on the helmet of Zhang Jun and the mermaid, the scenery can only be seen in the daytime. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Thousands of crimson rock towers, erected between the heart of the volcano and the red sand, are overwhelmed by the heavy sense of presence, mysterious and eerie, and terrifying.

It's like you'll never know what's going on here, how many untold stories are there.

"Such a terrifying place is the hometown of Xiao A's mouth, and what kind of terrorists do you say, this is simply a ghost town!"

The conch subconsciously shuddered.

"Those are cut by sandstorms and wind-blown sand, and for them, this is a gift from heaven to them!

In the past, many of their homes were destroyed by terrorists, and he said that the terrorists' base was in this terrifying underground.

I'm not sure you'll have seen that the most piled up of these towers wasn't built by their people at all.

You can send someone to see it. ”

After communicating with Xiao A, Xiao Yi looked at them and said.

"Conch, you're from the drone unit, and you should have no problem with intense reconnaissance of the place two kilometers away from being discovered, right?"

The mermaid looked at the conch and said.

"Small Meaning"

The conch came out of his pocket, cleared a box, and after pressing a certain switch, it belonged to the flying Martian drone, which appeared in the palm of his hand.

Buzzing flew away from the palm of his hand.

……

Through the real-time monitoring of the information transmitted by the drone, they quickly discovered that the rock building, which also looked like a holy relic, was surrounded by a flying Martian.

Sensing the danger, let the drone that flew out return at the first time.

Buzz!

"The other party's drone uses the same frequency, and if it weren't for my drone's quick response, we might have been exposed."

Analyzing the data on the virtual big screen, the conch recovered the drone.

"We can't get close at all, let alone with this big guy, it's easy to expose our whereabouts."

Ma Chao looked at Xiao A, who had been standing aside, and said.

"Little One, ask Little A, is there any other way to get to that place? For example, underground caves and the like. ”

Zhang Jun looked at Xiao Yi and said.

“……”

"He said it, but he said that it was their family's holy place, and ordinary people couldn't go in, he couldn't go in, otherwise he would be cursed to death."

Xiao Yi answered truthfully.

"You let Xiao A talk about the map, and we'll just go."

The mermaid, who is good at psychological portraits, doesn't want to continue to collect medicine like this.

“……”

After Xiao Yi's efforts, Xiao A, who originally insisted that if they went in, they would also be cursed, finally chose slippers to wish them good luck.

The strange thing is that Xiao A seems to be very talented in drawing, and in front of them, he directly draws the map with his fingers.

Looking at the twists and turns of the cave, they probably understood what Xiao A meant, if ordinary people go in, they will definitely turn around, but for these people, everything is not a problem.

Soon they appeared, at the entrance to this underground corridor, tick! Tick! The sound of running water reminded them of the cave and made them embark on a journey.

"God of War, my head hurts!"

As soon as he walked about fifty meters, Xiao Yi suddenly shouted.

"White horse, my head hurts! Somewhat out of breath! ”

Xiao San shouted.

"My head hurts! I can't breathe. ”

Xiao Er said.

“……”

"Let's run back!"

Ma Chao, who sensed the danger, reacted at the first time and ran back.

When they reappeared in front of Xiao A, looking at Xiao Yi's painful appearance, Xiao A's mouth was full of words like curses and retribution.

……

"Little One, don't go in, we're all fine because of our oxygen mask helmet, you stay here and wait for us."

The mermaid looked at it with a serious expression, and they said that they returned to normal not long after they came out.

"Are you really okay?"

Xiao Yi, who was full of terrifying memories just now, was a little worried about Zhang Jun.

"It's okay, our helmets are pretty good."

Zhang Jun looked at Xiao Yi and said.

“……”

"I believe that just now everyone has passed through the nanobots in the helmet, and we still have Martians who inhale helium-3."

Conch said with a serious expression.

"Helium-3 is a colorless, odorless, odorless and stable helium isotope gas, which is generally stored in gas cylinders at high pressure.

The natural helium-3 content is 1.38x10-6.

Asphyxia occurs when helium-3 levels increase so that oxygen levels fall below 19.5 percent.

Originally, the oxygen content of the Martian air was very low, and after passing through helium-3, they reacted.

I've just transmitted the discovery back to the base, and I'm afraid this natural helium-3 cave has already been known to the terrorists.

Everyone knows that helium-3 does not support combustion gases, so it is not so scary.

No need to worry! ”

The mermaid said as she walked.

"Mermaid, I suddenly have a bad feeling."

Zhang Jun said as he walked.

"Why?"

Asked almost in unison.

"Xiao A, he also said just now, that map is based on the murals handed down from our ancestors to show us, and there is a place in which a circle is drawn, could it be an underground lake?"

Zhang Jun said as he looked at the virtual map of the oxygen mask.

"The boat is naturally straight to the bridge, what's the use of thinking so much."

Mermaid said.

……

"There are still ten centimeters to the end, comrades, please transfer me back to the base, my mission is complete."

When the tunnel-digging robot completes its task, it immediately speaks.

Compared to Lan Lifei, the others were a little surprised and shocked.

"It's amazing, which means we have to dig the last ten centimeters by hand."

Said the missile.

"That's right!"

Lan Lifei took out the quantum transmission device in her hand for the first time, and after pressing a certain switch, this tunnel robot disappeared in front of them in the blink of an eye.

"I'll dig it alone, you don't have to meddle."

Lan Lifei's Shuangquan at this moment had turned into the blade of a tunnel robot and began to dig in front of them.

"Captain Blue, don't you need our help?"

Bai Xue asked sincerely.

"My sixth sense tells me that it's dangerous up there, so I'll do all the work! You should know that the effect of my Soldier Wolf Pill is to increase my sixth sense. ”

Lan Lifei said.

"Everyone is ready for battle, who knows what's up there!"

Bai Xue gave the order at the first time.

"Got it!"

The stars reacted in the first place. (To be continued.) )
