I live in the Martian wilderness!

"Captain, your suggestion is highly feasible," Xuanjian's voice rang out. "Although we don't have a blackout curtain, we can print one."

"Printing? Using divine power?"

"Yes, I have designed an ergonomically customized sleep mask for you based on your facial 3D scan data."

On the screen, a 3D model of an eye mask with a streamlined design that perfectly fits Gu Yu's facial contours was displayed.

"The material is a flexible carbon nanotube composite material with a printing thickness of 0.5 mm. It has 100% physical light blocking rate and excellent breathability."

"Estimated printing time: 7 minutes. Material consumption: approximately 3 grams of carbon."

Gu Yu looked at the design drawing, feeling both amused and exasperated, his voice tinged with a helpless self-deprecation:

"Using a multi-billion dollar machine to print an eye patch... This is probably the most extravagant thing I've ever done in my 24 years of life."

"Okay, start printing. And while you're at it... engrave a 'Zzz' design on it for me." Gu Yu rarely joked with Xuan Jian.

When Gu Yu took out the custom-made eye mask, which felt like the finest silk, from the retrieval port of the Divine Craftsmanship module, he was once again impressed by the power of the Divine Craftsmanship.

The lining of the blindfold automatically adjusted to fit the shape of his nose and eye sockets, ensuring that not a single ray of light could get in.

Gu Yu lay in his sleeping bag, enjoying the perfect darkness. "That'll do for now. I'll definitely build a bedroom for this light bulb in the backyard later."

[Sol 8, 20:00]

After an unknown amount of time, Gu Yu was awakened by a gentle wake-up music.

He took off his eye mask, glanced at the timer, and realized he had slept for a full four hours. This was the deepest and most restful sleep he had had since landing on Mars.

The physical fatigue vanished, replaced by a feeling of invigorating energy.

He took a tube of military nutritional paste from the locker and squeezed it into his mouth. The familiar nutty paste, though not exactly delicious, was the most efficient way to replenish his energy.

They ate while watching the panoramic screen.

Night had fallen, and the Martian sky was a deep indigo blue.

Phobos, which Earthlings call "Phobos," was like a bright diamond, slowly gliding across the sky.

Everything seemed so quiet.

Gu Yu glanced at the communication control panel; the signal indicator light on it was still red.

"Xuan," he spoke slowly, a hint of anticipation in his voice, "has the window of opportunity not arrived yet?"

Gu Yu glanced at the communication control panel; the signal indicator light on it was still red.

"Xuan," he spoke slowly, a hint of expectation in his voice, "did you receive any news while I was sleeping?"

"Captain, in the past 6 hours and 15 minutes, the Zhurong has not received any downlink signals from Tianwen-1. The communication window has not yet opened."

"Okay." Gu Yu nodded, not feeling too disappointed.

He sat back down at the control panel, a satisfied expression on his face as he reviewed his achievements.

"It's been less than two Martian days since we last sent a photo of Earth, hasn't it?"

"The exact time is: 1 Martian day 21 hours 45 minutes, Captain."

"Ha..." Gu Yu couldn't help but chuckle. "We've accomplished so much in less than two days."

"The well is drilled, the water problem is solved, and even the spirulina has been planted. If the command headquarters finds out, they'll probably be shocked."

"Xuan, give me a summary. All the substantial progress we've made since we sent our first message."

"Then prepare a concise and clear report, and send it back as soon as the window of opportunity appears."

"I want them to see that their astronauts aren't just waiting to die on Mars, but are pioneering new frontiers!"

"Understood, Captain. Generating the [Shennong Project Phase One Results Briefing] for you."

As Xuanjian's voice fell, several clear entries immediately appeared on the holographic screen, each followed by a series of exciting data and video materials.

I. Core Resource Acquisition: Water Resources

Results: Drilling has been successfully conducted to a depth of 20 meters outside the shelter, and the existence of a high-purity, potable freshwater ice layer (H₂O > 99.8%) has been confirmed.

Key equipment: The high-power deep well heating rod of Zhurong-1 has been successfully manufactured using in-situ Martian materials (iron oxide, carbon) and the "Shen Gong" module.

Production capacity assessment: The theoretical daily water production capacity exceeds 2000 liters, which fully meets the needs of survival and subsequent agriculture.

Video materials included: a video and data analysis of the crystal-clear ice core sample, as well as a 3D model of the heating rod and resistance test data.

II. Food Production System: Photobioreactor

Results: The "BZ-03" photobioreactor has been successfully assembled and started in the command compartment using spare parts provided with the ship.

Production status: High-protein Spirulina spores from the "Hope Seed Bank" have been successfully introduced into the culture medium, and the "space breeding" spectral scheme has been activated.

Growth forecast: Based on current light and temperature data, the first harvest is expected in 7 Martian days, and initial protein self-sufficiency is expected in 15 Martian days.

Video footage: The accompanying image shows the culture medium appearing as a faint green hue under a light pinkish-orange illumination, providing real-time monitoring.

III. Energy and Material Situation

Energy: The TianSuo nuclear power system is operating normally, with stable output power. The "Tianchi" battery pack currently has 77% charge. Energy reserves are extremely abundant.

Key consumable: A-3 geopolymer additive; initial stock was 50 kg, and after completing the three tasks of shelter sealing, well cementing and water tree modification, a total of 5.29 kg was consumed.

Current remaining inventory: 44.71 kg (89.4%).

[IV. Preliminary Results of Scientific Exploration (Supplement)]

Geological findings: The coordinates of the "Land of Adventure" have been successfully obtained and analyzed, along with complete geological core samples from the surface to a depth of 20 meters.

Major discovery: For the first time, it has been confirmed in the field that there is an ancient pure water ice layer with H₂O purity higher than 99.8% at a depth of 18 meters underground in this area.

This discovery overturns the traditional model that "groundwater in mid-latitudes must be high-salinity brine"!

Astrochemistry has revealed that isotope ratio analysis of ice core samples, specifically the deuterium/hydrogen ratio, provides new and compelling direct evidence for the existence of ancient Martian oceans.

Video materials: Includes ice core sample analysis videos and related spectral data.

Gu Yu looked at the near-perfect report card line by line, and the smile on his face grew wider and wider.

He glanced at the remaining amount of "89.4%" and nodded in satisfaction.

That 50 kilograms of "super glue" is his strategic reserve for building larger-scale greenhouses and facilities in the future, and he must use it sparingly.

This is no longer a simple progress report.

This is a balance sheet and a feasibility study report.

It was the most powerful answer I could give to the command center and to everyone who cared about me, demonstrating that I was able to survive!

"Xuan, the report content is confirmed to be correct and is listed as the highest priority for issuance."

"Now, we just wait for the signal."
