I live in the Martian wilderness!

Gu Yu breathed a sigh of relief, but the work wasn't over yet. "Xuan, prepare to activate the Divine Craftsmanship Module and execute the filling and sealing procedure."

This 3D printing module, codenamed "Miracle Worker," operates on a principle hundreds of times more complex than the original technology of 2025. It is more like a mobile materials processing plant and a super kiln.

The harvesting arm at the front of the module is inserted deep into the edge of the gap between the rock wall and the base module, drawing in rubble and Martian soil.

After rapid screening, these local materials are fed into the mixing chamber and injected with additives.

Subsequently, two fluids were precisely pumped in: one was the "high-temperature geopolymer adhesive" that was carried in, and the other was "10% enriched boron carbide nanoparticles".

With high-pressure injection, the mixture filled the gaps.

But this is not the end, but the beginning.

The microwave array behind the printhead is activated instantly, converting the surging electrical energy of the Tianchi battery pack into a high-frequency energy field, which is then injected into the newly filled material.

Immediately afterwards, a high-power laser beam swept across the surface, instantly raising the core temperature to 2450℃!

At this terrifying temperature, the Martian basalt regolith underwent a physical phase transition instantly.

The originally loose sand particles melted directly and then formed complex chemical bonds with the geopolymer binder.

Within seconds, the flowing lava cooled and solidified, forming a deep black basalt glass.

During this process, the boron carbide particles mixed in are uniformly sealed within this dense glass matrix.

It is not only a perfect airtight ring, but also a highly efficient neutron absorption shield.

After radiation from deep space penetrates the thick wall, the remaining secondary neutrons will be captured by this boron-doped glass.

Through the helmet's thermal imager, Gu Yu saw that the gaps were emitting a dazzling white light, which was the terrifying heat released when the rock was instantly sintered!

Within just half an hour, all the gaps between the base module and the rock wall were completely sealed by this super composite material that integrates load-bearing capacity, airtightness, and radiation protection.

"The final step is to seal it with a dustproof cap."

The Shen Gong module once again stirred up the surrounding loose soil, mixed it with short-cut basalt fibers, and sprayed a 30-millimeter-thick protective layer onto the surface of the glass ring that had just cooled.

This rough "dust cover" will protect the delicate glass enclosure from sand and dust erosion and electrostatic adsorption over the next few decades.

[Filling and sealing complete. Internal structural integrity 100%, airtightness meets standards. Surface neutron flux has decayed below the safe threshold.]

After doing all this, Gu Yu finally parked the Tissot at the entrance of his new home and connected it to the thick, high-power cable.

This steel behemoth will become the eternal guardian and energy core of this home.

"Xuan, activate the environmental control system. Begin pressurizing the base."

"Command confirmed. Open the external air intake valve and begin pumping in the multi-stage filtered Martian atmosphere."

The air pressure reading on the screen jumped slowly, strictly executing the aerospace-grade "staged pressurization procedure" to prevent air pressure surges from impacting the newly sintered sealing layer.

"Phase 1: Air pressure 0.1 atm. Acoustic leak testing is underway... No whistling sound from the sealing layer, airtightness is good."

"Phase 2: Air pressure 0.5 atm. Structural stress monitoring normal... No cracks found in the basalt glass sealing ring."

Gu Yu stared at the screen, watching the cabin model representing "home" gradually change from red to green.

Ten minutes later.

"The air pressure has reached 1.0 atmospheres, the carbon dioxide concentration inside the cabin is 96%, and the temperature has risen to 22°C. All environmental indicators are perfect."

"very good."

Gu Yu took a deep breath and unbuckled Tissot's seatbelt.

He walked through the docking passage on the side of the Tissot and arrived at the airlock leading to his new home, where the indicator light was already a reassuring green.

"laugh--"

As the hatch slid open, Gu Yu stepped inside.

The soft lights on the walls were already on, illuminating the entire room as bright as day. The air circulator fan hummed softly, as if welcoming its owner home.

He raised his hand and pressed the unlock button on the helmet.

"Click".

Gu Yu finally took off his heavy helmet.

He stood in his brand-new home and took a deep breath.

The high concentration of carbon dioxide instantly filled his lungs, giving him a feeling of satisfaction similar to oxygen intoxication.

Although the air was dry, it carried a faint smell of ozone—that was the smell of his home.

"Xuan, report on the final status of the 'Oasis One' shelter."

"Understood!" Xuanjian's clear voice echoed in the cabin, no longer through bone conduction headphones, but through real air transmission.

Data streams and external monitoring images are projected onto the holographic screen in the command center.

"The main body of the command module has been perfectly embedded into the rock wall interface, and the external basalt glass gas seal ring has been completely cooled and solidified. Laser radar scanning has not detected any structural microcracks."

On the screen, the view switched to footage taken by the Sky Surveyer from a distant high ground.

From this perspective, the entire shelter resembles a fortress deeply embedded in the shadow of the crater.

The futuristic, silver-gray metal hull was firmly locked within the ancient Martian rock face by a black basalt dust cover.

It created a strong visual impact—it was the forced implantation of civilization into barbarism!

Xuanjian pulled up a 3D structural diagram of the base. "Captain, the current internal shelter is divided into two main functional areas."

"The safe zone, which is our command and living quarters, is maintained at a constant temperature of 22°C and a constant pressure of 1 atmosphere. Backup power is at 40% remaining."

"You can rest in this area without wearing combat gear."

Gu Yu looked around; everything was exactly the same as what he had seen on the Candle Dragon One: control consoles, folding beds, food heating units…

The only difference is that the items here no longer float around, but land steadily on the ground.

Xuanjian highlighted the latter half of the structural diagram: "The industrial expansion area, that is, behind the command cabin, is that unmodified natural lava pipe."

"Pipe status: vacuum, darkness, extreme cold. You must wear combat gear to enter."

Gu Yu walked to the innermost part of the room, to the round hatch leading to the backyard, and pressed the open button.

"laugh--"

As the hatch slid open, no gas rushed in because there was a vacuum behind it, but a visible white chill rushed out.

Behind the door was complete darkness, so he turned on the powerful searchlight mounted on the outer wall of the hatch.

A dazzling beam of light pierced the darkness in an instant, illuminating a magnificent yet desolate underground world.

The walls and ceiling are rough, dark gray basalt, full of traces of ancient lava flows, reflecting a cold, hard luster under the light.

This natural cave was much taller and more spacious than the command center he was in, and it stretched deep into the earth.

Gu Yu closed the door to the backyard, shutting out the darkness and cold once again.

He walked back to the center of the command module, where there were no longer any physical windows that allowed direct access to the universe.

The only window is a 4K resolution holographic screen that takes up the entire wall.

At this moment, the screen is displaying high-definition footage transmitted in real time from the external camera of the TianShuo engineering vehicle—a magnificent purple sunset on Mars.

Exhaustion gripped his entire body. He sat down in the chair in front of the control panel, and his nerves, which had been tense all day, finally began to relax a little.

Because on this desolate planet, he finally drove in the first nail for himself and for human civilization!
