I live in the Martian wilderness!

[Mars Day 11, 18:30]

As evening fell, the Tissot truck, fully loaded with raw materials, slowly drove back to the gate of the shelter.

Gu Yu parked the Skywatch back in its original position, connected it to the charging station, and then returned to the warm cockpit of the Skywatch.

"Xuan, start the 'low-temperature grinding' program and grind all the raw materials we collected today into powder, then sort and store them."

"Understood, Lieutenant Colonel. Automated grinding operation initiated. Expected completion of 1.5 tons of sulfur powder production in 8 hours."

Gu Yu leaned back in his chair, feeling the dull vibrations coming from inside the Divine Craftsmanship Module, but he didn't want to move at all.

From the early morning exploration to the afternoon's remote control and forced mining, he was somewhat exhausted.

"Lieutenant Colonel," Xuanjian's voice rang out at the opportune moment, "before you rest, I need to report to you on the latest progress of the Shennong Project."

"Oh?" Gu Yu's spirits lifted, and his fatigue dissipated somewhat. "Tell me about it."

On the main screen, the real-time monitoring screen of the "photobioreactor" immediately switched to the main screen.

In the video, the once clear liquid inside the winding glass pipe has now been tinged with a light emerald green.

"Reporting to the Colonel, 49 hours have passed since you sowed the first batch of Spirulina platensis spores two days ago."

"Under the continuous irradiation of the space breeding spectral scheme, all algal species have been activated and entered the logarithmic growth phase. The current biomass density has reached 0.8 g/L."

Xuanjian stood beside him, projecting a steep curve representing the growth rate.

"Based on the current growth rate, we expect to be able to carry out the first harvest in 5 days, which is the 16th Martian day."

"However," Xuanjian then issued a warning, "this small reactor has a volume of only 120 liters."

"At the latest, the algae density inside will reach its saturation limit by the 14th day."

"Before that, we must transplant them into large 'racetrack pools,' otherwise they will stop growing due to overcrowding, or even die in large numbers."

Gu Yu looked at the timeline filled with a sense of urgency and nodded.

This means that he must spend the next few days both "farming" and completing "infrastructure construction".

"Very good." He quickly assumed the role of commander. "Then, based on our mineral exploration results today, devise the most efficient engineering plan for the next few days."

"Plan generated, Lieutenant Colonel." Xuanjian's efficiency was terrifying. A clear Gantt chart appeared on the screen.

[Phase I Ecological Zone Construction Plan]

Day 12 (Preparation Day):

Daytime: 160 "carbon-sulfur composite interlocking bricks" (Mars bricks) will be mass-produced automatically by the Shenggong module, with an estimated time of 13.5 hours.

Evening: You personally operate the Tissot to move all the bricks and construction tools to the designated construction site in the backyard.

Nighttime: Tissot recharges and recovers.

Day 13 (Construction Day):

Full Day: You will need to complete the construction of the partition wall with the laser guidance and assistance of AI. Estimated time: 8-10 hours.

Day 14 (Final Day):

Morning: Conduct final airtightness testing on the walls and begin initial pressurization and heating of the "Phase I Ecological Zone".

Afternoon: Prepare the printing materials for the running track pool, in preparation for the "Printing Pool" work on Day 15.

"A perfect plan." Gu Yu looked at the tightly linked schedule and felt a sense of security.

On one side, an automated factory is firing bricks; on the other side, spirulina is quietly growing in a biological laboratory.

The fact that the two key technology trees could advance in parallel gave Gu Yu a great sense of satisfaction from strategic planning.

Gu Yu relaxed, took out a tube of nutritional paste from the storage compartment, and squeezed it into his mouth.

He held the nutritional paste in his mouth, watching the green color on the screen slowly intensify, then glanced at the mountain of yellow sulfur outside the window.

In this wasteland, anything that reminds him of the earth is priceless. And he is creating these "flavors" with his own hands.

"Xuan, today's work is finished." Gu Yu shut down most of the Tian Shuo system, leaving only the automation program of the Divine Craft module.

After connecting to the airlock, Gu Yu, exhausted, returned to Oasis No. 1 Shelter.

The main lighting in the command cabin had been turned off, and the entire space was enveloped in a light pink glow emitted by the "photobioreactor".

The strange light, a mixture of red, blue, and green light, bathed the walls and ceiling in a dreamlike hue.

The faint emerald green inside the pipe seemed even more intense than during the day.

Countless tiny bubbles slowly rose under the light, like a cosmic nebula full of the mysteries of life.

He took off his helmet, feeling the warm, carbon dioxide-rich air, and all the muscles in his body gradually relaxed at that moment.

Another, more practical physiological need arose.

Gu Yu shook his head with a wry smile and walked into the small sanitation unit in the corner of the shelter.

Here, he could finally temporarily shed his heavy armor and solve the problem in a more "civilized" way.

A few minutes later.

"Sizzle—"

A slight motor hum lasted for a second, followed by a crisp "glug" sound of air being pumped out. The status light on the pump changed from red to green.

I stopped paying attention to the stars outside the window, and I stopped thinking about tomorrow's project.

He crawled into his soft sleeping bag, put on his eye mask, and fell into a deep sleep bathed in the soft pink light.

...

[Mars Day 12, 07:00 AM]

What woke Gu Yu was not the alarm clock, but Xuan Jian's crisp voice, which carried a hint of "taking credit," ringing out precisely on time.

"Good morning, Lieutenant Colonel. Tissot's energy reserves are at 98%. Automated grinding tasks have been exceeded."

Gu Yu rubbed his sleepy eyes and sat up. The main screen had automatically switched to the material warehouse monitoring screen of the Shen Gong module.

In the video, the huge external silo is completely filled with a fine, bright yellow powder.

"We have already prepared 1.6 tons of high-purity sulfur-based adhesive powder, and we can start today's work at any time."

Gu Yu was pleasantly surprised by the number. "Well done, Xuan."

After washing up, I sat back down at the command post. "Xuan, we have two critical tasks today: the carbon fiber plates for the runway pool and the Martian bricks for the partition walls. I need the most efficient production plan."

[The design plans for the "Phase I Ecological Zone" have been retrieved for you.]

The plan has been generated.

[Day 12 Production Plan]

Phase 1 (8:00 AM - 10:00 AM): Low-temperature printing of carbon-sulfur composite boards.

[Task]: Produce all the "carbon-sulfur composite panels" needed to build two runway pools (15 square meters + 5 square meters).

[Working Time]: Expected to take only 2 hours.

"The core advantage of this task lies in 'low-temperature molding.' Simply heat sulfur to its melting point of 120°C to turn it into 'hot melt adhesive,' which can then be bonded to the carbon foam skeleton."

"The total printing material weighs approximately 334 kilograms, and the total energy consumption is estimated to be only 100 kilowatt-hours. It can be completed in 2 hours at a power output of 50 kilowatts."
