Courtyard House: Primordial Chaos Pearl

As the dawn light of Vesta illuminated the edge of the rift valley, the Red Star-130H geological adaptive agricultural machine had already begun ice-breaking operations. The improved superlattice drill bit rotated and drilled into the surface, precisely reaching the ice layer at a depth of 320 meters. White ice chips slowly rose under low gravity, like a silent snowfall. Simultaneously, Chaos Beads-optimized low-temperature solidification slurry was injected into the borehole wall to prevent rock collapse, and a passage to the deep ice vein was gradually taking shape.

"Ice extraction is progressing smoothly. We can extract 10 cubic meters of pure water per hour, which fully meets the initial needs of the outpost," the operator reported. The water level monitoring curve on the screen was steadily rising, and the water treatment module had begun to decompose the ice water into hydrogen and oxygen to replenish the energy reserves of the Starship-1.

Yan Jiecheng stared at the readings of the rare earth detector, his tone excited: "The highest concentration of rare earth minerals is found 3 kilometers east of the rift valley, with lanthanum and cerium content reaching 85%! We can use the 'in-situ leaching + superconducting purification' technology to extract them directly underground, avoiding large-scale surface excavation that could damage the geological structure."

Lin Xiangyang added, "Lighthouse V5.0 has simultaneously generated mining paths for the veins, avoiding key areas of the ice layer, and has also set up geological monitoring points, deploying a micro-seismic sensor every 10 meters to prevent mining from causing cracks."

Just as ice mining and rare earth extraction were proceeding simultaneously, the micro-seismic sensor suddenly issued an urgent alarm:

[Strong geological tremors detected] [New cracks appear at the edge of the rift valley] [The cracks have reached a length of 50 meters and are spreading at a rate of 0.5 meters per minute] [Only 100 meters from the ice mining tunnel!]

The ground-penetrating radar image on the observation screen shows a dark red crack, winding like a venomous snake, extending towards the ice-breaking passage. Vesta's deep rock layers already had numerous hidden fractures due to the impact; the disturbance from rare earth mineral mining, coupled with the stress release caused by the melting of the ice layer, ultimately led to geological instability.

"Stop mining operations immediately!" Lin Dong decisively ordered, "Switch the Red Star-130H model to reinforcement mode, carry high-strength shape memory alloy anchor bolts and solidification grout, and drill holes along both sides of the crack for reinforcement; Xiangyang, activate the Lighthouse's 'Geological Emergency Simulation' to predict the crack's spread path and plan a safe evacuation route."

Lin Xiangyang's fingers flew across the keyboard, the Lighthouse system's computing power was at full capacity, and a simulation of the crack's spread was quickly generated on the screen: "It is estimated that the crack will reach the ice channel in 15 minutes. A reinforced barrier must be built around the channel!"

Yan Jiecheng personally operated the Hongxing-130H agricultural machine. The robotic arm precisely drilled holes, and shape memory alloy anchor rods were embedded into the rock strata like steel nails. Solidifying grout was then injected, which quickly solidified upon cooling, forming a sturdy protective wall. However, the cracks spread much faster than expected, approaching the reinforced barrier in just 10 minutes.

"The barrier can't hold!" Yan Jiecheng roared. "The ice passage is at risk of collapsing; we must abandon part of the passage and blast away the path of the crack!"

Lin Dong's eyes sharpened: "Agreed. Use a directional blasting module to detonate 5 meters in front of the crack to create a shock-absorbing zone; at the same time, close the sealed door at the front of the passage to protect the already mined ice layer and equipment."

The shockwave from the directional blast propagated underground, and the crack spread curve on the observation screen instantly flattened. Fifteen minutes later, the vibrations stopped, and the crack finally stopped in front of the shock-absorbing zone, only 3 meters away from the ice passage. Inside the command cabin, everyone breathed a sigh of relief, their backs soaked with sweat.

He Yushui wiped the sweat from his forehead and suggested, "This crack was caused by an imbalance of geological stress, so we can't continue mining blindly. We can adjust the plan and first use the root system of symbiotic plants to reinforce the surface—its roots can secrete organic cement to form a stable structure with the soil, and then gradually advance the mining."

Lin Dong nodded: "Let's do it this way. Yu Shui, you're in charge of sowing symbiotic plant seeds around the cracks and in the outpost area; Yan Jiecheng, replan the rare earth mining route to avoid stress concentration areas; Xiang Yang, optimize the lighthouse's geological monitoring algorithm to improve the sensitivity of vibration early warning."

The sowing of the symbiotic plants went more smoothly than expected. He Yushui and her team scattered seeds coated with microbial agents on the ground around the cracks. With the help of a small amount of water from the melting ice, the seeds sprouted within 24 hours, and their tiny roots spread rapidly, forming a fine net that firmly held the loose rock strata.

"The microbial inoculant can accelerate seed germination, and the organic binder secreted by the roots has begun to play its role," He Yushui reported. "Microseismic monitoring shows that the stability of the rock strata around the crack has increased by 40%, and after another week of growth, it will meet the geological conditions required for mining."

At the same time, the alliance has also made breakthroughs in rare earth purification technology. Lin Dong combined the "superconducting magnetic separation purification technology" improved by Chaos Beads with the leaching processes of various countries to develop an integrated solution of "in-situ leaching - superconducting purification - recycling", which increased the rare earth extraction rate from 80% to 95% and did not produce wastewater pollution.

"Superconducting magnetic separation technology can accurately separate different rare earth elements with a purity of 99.9%." Lin Xiangyang presented the purification data at the alliance video conference. "These rare earths will be used in the manufacture of next-generation aerospace materials, which can improve the radiation resistance of starships by 40% and double the wear resistance of geologically adaptive agricultural machinery."

The Alliance Council quickly adopted a rare earth resource allocation agreement: "Allocation will be based on 'mining contribution + technology investment + demand priority,' with Red Star Agricultural Machinery taking the lead in mining and refining, ESA responsible for material processing, and Brazil, India and other countries receiving priority application quotas to jointly promote the upgrading of interplanetary agricultural equipment."

When the news reached the courtyard, the Interstellar Agriculture Museum erupted in cheers. Yi Zhonghai, Liu Haizhong, and Yan Bugui, along with the children, excitedly discussed the geological model of Vesta and the specimens of symbiotic plants.

"Lin Dong and his team are amazing! Not only did they find rare earth elements, but they can also use plants to reinforce the planet's surface!" Yi Zhonghai exclaimed. "This is true harmony between humanity and nature!"

Liu Haizhong held up a calligraphy scroll he had just written, bearing four powerful characters: "Solidify the Soil and Enhance the Treasures." "I'm giving this to them, wishing them a smooth journey on Vesta, and that they make good use of rare earth and water resources!"

Yan Bugui said with a smile, "I've already included the rescue stories from the geological fissures and the soil-stabilizing principles of symbiotic plants in the museum's explanations. The children are all captivated by them, and many say they want to study geological engineering in the future to protect planets in space!"

Seeing the museum during the video call filled Lin Xiangyang with warmth: "Grandpa Yi, Grandpa Liu, Uncle Yan, thank you for your support. The geology of Vesta is now stable, and rare earth purification is progressing steadily. Once the first batch of purified rare earth is transported back, we can manufacture a new generation of aerospace equipment!"

On Vesta at night, the lights of the outpost mingled with the starlight. Symbiotic plants had formed a lush green belt around the cracks, their roots firmly anchoring the rock strata; in the rare earth purification workshop, superconducting magnetic separators were operating at high speed, the purified rare earth ingots gleaming with a metallic luster; the ice mining channel had been reinforced and resumed operation, with pure water continuously being delivered to the outpost.

Standing before the observation screen, Lin Dong gazed at the rift valleys and vegetation belts of Vesta, his heart filled with unwavering certainty. The crisis posed by the geological fissures not only led them to a safer development model but also validated the ecological value of symbiotic plants. In the future, they will focus on "ecological reinforcement + precision mining" to transform Vesta into a "resource and material hub" of the asteroid belt.

Lin Xiangyang walked to his father's side and wrote a new note in the lighthouse system's log:

"The Rift Valley is in peril, but we break through with wisdom; rare earth elements shine, and we achieve harmonious coexistence. Every challenge on Vesta teaches us to be more respectful and innovative. May we, with ecology as our foundation and technology as our wings, continue to write a harmonious chapter in interstellar agriculture and resource development on this planet."
