Age of Cataclysm: I can light up the technology tree

Looking at the "soil" that had turned into crimson debris, Bai Yixuan's face turned ugly.

"broken."

He whispered, "How long of drilling steel pipe have we prepared?"

Hong Fan thought for a moment: "To be on the safe side, I probably carried him about thirty meters away."

"What's wrong?"

Bai Yixuan breathed a sigh of relief and pointed at the drill hole a few centimeters in front of him: "Look, the drill drilled five meters, and all that came out was dust and fine particles."

"Professor Lu estimated at that time that the depth of this part was only two to three meters!"

After hearing this, Hong Fan also realized the problem.

Bai Yixuan continued with a slightly solemn expression: "Currently, we don't know how deep this part is. Fortunately, we brought a thirty-meter drilling steel pipe. Otherwise... I guess we wouldn't even be able to see the shadow of the underground ice!"

While talking, Bai Yixuan installed the drilling steel pipe back on the drilling machine.

"Go on, I hope we can find so-called Martian life within the length of the steel pipe."

…

At the same time, inside the American Mars module one thousand meters away.

"Bip! Blop! Blop!"

Just as everyone was getting ready to go to bed and end this tiring and depressing day, a piercing alarm sounded from the speakers of the Mars cabin.

Andrew, who had just laid down on the single bed, suddenly opened his eyes and jumped up from the ground like a carp.

What's going on? !

Listening to the alarming siren, a flash of anger flashed in Andrew's eyes.

Damn it, aren't the Xia people coming again? !

Without time to think too much, he put on his clothes casually and ran directly in the direction of Cabin No. 1.

Tens of seconds later, Andrew pushed open the closed door of Cabin No. 1.

He immediately looked towards the radar.

Nothing unusual.

He was stunned for a moment, then turned around and glanced around.

The next moment, his pupils shrank suddenly!

"Captain! What's going on?!"

Bruno and Joey's inquiries came from behind: "Are the Xia people here again?"

"no!"

Hearing Andrew's response, Bruno and Joey relaxed slightly, and the expressions on their faces relaxed a lot.

"There is something wrong with our central control computer..." Andrew hurriedly walked inside and said a "hot" sentence.

"hiss!"

"WTF??!"

Bruno and Joey gasped suddenly, and their eyes widened suddenly!

…

"Bruno?" Andrew looked at Bruno sitting in front of the computer solemnly, and asked in a low voice: "What's going on?"

As he spoke, Andrew's eyes were filled with panic and uneasiness.

This is the central control computer!

Once something goes wrong, the three of them will die in this small Mars cabin!

Bruno typed on the keyboard a few times and looked at the several lines of error codes that appeared on the screen. His face instantly turned ugly.

He slowly turned his head and glanced at Andrew beside him with deep meaning: "Captain, you were right."

"There's something wrong with our air circulation equipment."

"To be precise, there is a problem with the carbon dioxide absorber in the air circulation equipment."

"According to the current progress, in about three days, the Mars cabin will be filled with a large amount of carbon dioxide and other toxic gases."

"Even if there is enough oxygen, excess carbon dioxide can kill us."

Andrew's expression changed drastically.

In panic, an idea flashed in his mind: "Bruno! I remember that Pathfinder 3 carried some accessories. Is there a carbon dioxide absorber among them?"

Before Bruno could reply, Joey on the side said: "Yes! There must be!"

"To prevent accidents, NASA specially equipped two complete sets of air circulation equipment!"

Upon hearing this, Bruno breathed a sigh of relief.

The original solemn expression disappeared, replaced by an indescribable sense of relaxation.

He lightly shrugged and said in a joking tone: "Everyone, this is a false alarm!"

"I thought we had to ask Xuannv 2 next door for help. Now it seems that our NASA is quite reliable!"

He was joking as he opened the door of Mars Module No. 1: "Come on, you two, let's go to the warehouse to find spare air circulation equipment!"

…

Mars module No. 3.

As a warehouse that supports the lives of three astronauts for three months, the largest number of items in No. 3 cabin are various compressed foods.

Of course, in addition to a variety of compressed biscuits, NASA also "thoughtfully" prepared some instant cans to improve the meals for these astronauts.

Although the taste of these instant cans is not very good, they are still much better than compressed biscuits.

Andrew and Bruno moved the boxes full of food and fresh water aside in front of them with great pain.

"Found it!"

Andrew looked at the box with the air circulation equipment logo engraved in front of him, and his eyes suddenly lit up.

Hearing Andrew's voice, Bruno also breathed a sigh of relief.

"I finally found it..." Bruno reached out and wiped the beads of sweat on his forehead, "We almost rummaged through this warehouse!"

As he spoke, Bruno reached out and tugged on his collar, and said with a strange expression: "By the way, do you feel a little stuffy?"

"Have carbon dioxide levels started to rise?"

Joey raised his watch to look at the data, then rolled his eyes.

"What are you talking about?"

"The current carbon dioxide concentration in the cabin is 0.1% higher than normal. It's strange that you can feel it!"

"It's purely psychological!"

Bruno smiled awkwardly and squatted down to help Andrew drag out the big box.

After the box was opened, the three astronauts looked at the brand new air circulation equipment inside, and a hint of relief flashed in their eyes.

"I remember that the air circulation equipment needs to be replaced outside the Mars cabin, right?" Andrew frowned as he found the carbon dioxide absorption device from it, "It seems that we have to go out of the cabin again."

...

Mars cabin No. 5.

As the only channel between the Mars cabin and the outside world, the airlock cabin plays a huge role.

When leaving the cabin, the airlock cabin can ensure that the cabin has the same air pressure as the Martian atmosphere.

When entering the cabin, the airlock cabin can ensure that the cabin has normal atmospheric pressure.

These two points not only ensure the safety of the Mars cabin, but also the safety of the astronauts.

Andrew and Bruno, wearing bulky silver-white space suits, looked at each other through the arc-shaped glass masks.

The next moment, Andrew reached out and pressed the button on the console.

"Beep!"

"Pressure balancing..."

"Pressure balanced!"

As the green light came on, Andrew squatted slightly and grabbed the outer gate leading to Mars at the end of the airlock with both hands.
