I live in the Martian wilderness!

The unique "mortise and tenon interlocking structure" of the Mars bricks demonstrated its power at this moment.

No cement is needed between the bricks. As long as they are aligned with the locking points and dropped, they instantly form a rigid whole, just like gears meshing.

One floor, two floors, three floors... the walls grew rapidly, soon exceeding Gu Yu's height.

Gu Yu looked up at the empty area above him: "Xuan, let's change tactics. I can't reach up there anymore, let's switch to the ground pre-installation mode."

"Understood, Lieutenant Colonel. The procedures have been updated."

This time, after the robotic arm picked up the brick, it did not lift it directly. Instead, it suspended the brick at the height of Gu Yu's chest and slightly flipped it to reveal the groove at the bottom of the brick.

Gu Yu picked up a sealing strip and, using the elasticity of the rubber, pressed it forcefully into the tenon groove at the bottom of the brick.

Thanks to the interference fit, the sealing strip is firmly held in place and will not fall off.

"All installed, send it up!" Gu Yu patted the brick.

The robotic arm then rose high, like a giraffe stretching its neck, carrying the brick with a "sealed bottom" to a height of 3 or 4 meters.

"Aim...and drop!"

Although they were several meters apart, Tissot's sensor accuracy was sufficient to compensate for the lack of line of sight.

The brick fell precisely, and the sealing strip at the bottom perfectly engaged with the protrusion on the top of the brick below.

This method of loading on the ground and delivering goods from high altitude is extremely efficient.

As noon approached, with the last brick being inserted, only a few centimeters of irregular gap remained between the entire wall and the groove at the top of the hole.

This is also the most crucial step – capping the roof.

This is a dead end, also known as a "sealing gap," where a formed brick cannot be inserted, and the robotic arm is powerless to do so.

"Xuan, raise the Sky Shuttle's repair platform and send me up there."

Gu Yu stood on the hydraulic lifting platform on the side of the Sky Shuttle, and with the hum of the motor, he was sent to the top of the cave, which was 5 meters high.

He gripped the flexible injection tube connected to the Shenggong module tightly in his hand.

"Give me the remaining sealing strips."

Gu Yu took the rubber strips handed to him by the robotic arm and forcefully stuffed them into the deepest part and sides of the crack in the top of the wall, as a "temporary dam" to block the fluid.

"Activate the divine process, inject 'A-3 Geopolymer Adhesive,' pressure 50%!"

Driven by the pump pressure, the gray, viscous slurry was slowly injected into the gap between the top of the wall and the rock groove through the pipe.

This material not only has strength comparable to rock, but also has a unique characteristic—a slight volume expansion during solidification.

It will act like an ever-expanding wedge, generating enormous tension that will firmly "push" the 5-meter-high wall between the top of the hole!

"Sizzle—"

Gu Yu held the microwave transmitter of the Shen Gong module and swept it across the injection port.

The slurry rapidly polymerizes under microwave heating, emitting a puff of white smoke, and hardens into a gray rock seal within minutes.

Gu Yu lowered the platform, took a few steps back, and looked up at the towering, dark red wall in front of him.

The black basalt bricks and dark brown rubber lines resemble a heavy dam, completely blocking out the emptiness and desolation behind it.

"Done!" Gu Yu breathed a sigh of relief. "Xuan, let's retreat to Oasis One. Go inflate this new area!"

……

A few minutes later, Gu Yu returned to the Oasis One command center and went directly to the environmental control console.

He found the UI for "ECLSS supplement pump" on the program page and clicked, "Xuan, prepare to pressurize."

"Lieutenant Colonel, I had already rehearsed the pressure-increasing plan before you gave the order."

"If we use the ECLSS supplemental pump that comes with Oasis One to pressurize the 600 cubic meter space in the backyard to 0.8 atmospheres, it is estimated to take 14 hours."

"14 hours? That's a bit long."

"Yes, Lieutenant Colonel. So I suggest you choose another option."

Xuanjian brought up a 3D model of the Tissot on the screen and highlighted an interface on its side.

Next to it is a video showing the tent being inflated during the rescue of the Zhurong ship.

"We can replicate the successful experience of waking up the Zhurong ship by utilizing the 'heat exchange and gas circulation module' on the Tiansuo."

"Its power is five times that of the ECLSS pump, and it can directly blow hot air using nuclear waste heat."

"Through a multi-functional fluid transport cable, the Tissot is used as an external booster pump, which is transferred via the Oasis One's external service panel to directly inflate the backyard."

"The total time is expected to be reduced to less than 3 hours."

"This is true industrial-grade speed!" Gu Yu finally smiled. "Let's do it!"

Without the slightest hesitation, he fastened his combat suit and helmet again, opened the airlock, and stepped into the frigid Martian evening.

The sky outside had completely darkened, with only the huge searchlight of the Sky Shuttle illuminating the open space in front of the shelter as if it were daytime.

"Xuan, hand me the multi-functional fluid transport cable."

The mechanical arm on the roof of the Tianshuo car was already ready. It deftly removed the thick, python-like black cable from the side bracket and slowly handed it to Gu Yu.

The pipe was extremely heavy; even under the low gravity of Mars, Gu Yu felt as if he were carrying a solid iron rod.

He gripped the silver metal connector at one end of the cable with both hands and aligned it with the interface marked "Environmental Recirculation Output" on the side of the Tissot vehicle.

"Xuan, wait a moment. There's a little dust on the interface. Let me clean it first."

Gu Yu did not force it in directly, but carefully wiped the sealing ring of the interface.

In such high-pressure operations, even a tiny grain of sand could cause a fatal leak.

After confirming that everything was correct, he used both hands to push the heavy connector in slowly.

"Click—"

With the heavy-duty latch automatically engaging, Gu Yu dragged the other end of the pipeline toward Oasis One.

He skillfully lifted the dust cover of the "front-end service panel" next to the airlock, revealing a row of neat, standardized interfaces underneath.

Align the connector with the port marked "External Fluid/Gas Injection" and push it in again.

"Click—"

The second click of the latch sounded.

Thus, a lifeline connecting Tissot and the oasis was established.

"Done."

Gu Yu clapped his hands, turned around, and returned to the warm command cabin.

He looked at the two green connection indicator lights on the screen, which were both lit up, and gave the final instruction.

"Open the bypass valve on Oasis One's pipeline to direct the externally injected gas directly to the backyard ecological area."

"Tissot gas supply mode activated! Full power!"

[Process begins]

"boom--!!!"

The Tissot's air intake grille, like a whale, greedily devours the cold, thin Martian atmosphere.

After passing through the internal filter, the gas is directly pumped into the scorching heat exchange loop of the nuclear reactor.

The -60°C gas was instantly heated to 80°C. Then, it was forcibly pressurized by a 15-kilowatt turbine fan and rushed into the Oasis One's pipeline network along the thick cable!

Inside Oasis One, this violent heat flow did not enter the sophisticated circulation system of the living area.

Instead, it was guided directly to the airlock in the backyard of Oasis One by a bypass valve that Gu Yu had just opened remotely.
