Courtyard House: Primordial Chaos Pearl

In the midsummer of the Hongxing Agricultural Machinery Industrial Park, a groundbreaking test is underway in the underground laboratory of the R&D center. Inside the temperature- and humidity-controlled sealed cabin, the "Hongxing-110" deep-space breeding agricultural machine stands quietly, its entire body covered with a radiation-proof alloy coating. The seeding head at the end of the robotic arm is aimed at the artificial lunar soil in a specially made container. This is a simulated soil created by the R&D team in conjunction with the aerospace department, mimicking the weathered layer of the moon. It has coarse particles, no organic matter, and contains trace amounts of perchlorate.

Lin Dong stood in front of the observation screen, clutching a copy of the latest lunar environmental data from NASA: "The moon's low gravity, strong radiation, and constant floating lunar dust will not only damage the precision components of agricultural machinery but also affect the respiration of plant roots. More importantly, the lunar soil lacks humus and nitrogen, so even if space rice seeds can germinate, they will have a hard time surviving."

He Yushui pulled up the closed-loop ecological experiment data from "Lunar Palace-1" and swiped his finger across the crop growth curve on the screen: "We need to build a miniature closed-loop system so that agricultural machinery can not only sow seeds, but also achieve the integration of 'planting-waste recycling-nutrient cycling'. Referring to the CELSS technology principle, we can convert the astronauts' domestic wastewater and plant straw into nutrient solution, so that we can get rid of our dependence on Earth for supplies."

Yan Jiecheng was debugging the multi-mode power system of the agricultural machinery, sweat beading on his forehead: "I drew on the PHEV hybrid technology of the mountain 'agricultural tank' to design a solar-nuclear dual power module for the deep-space agricultural machinery. During the lunar day, it is powered by flexible solar panels, and at night, it switches to a small nuclear battery to ensure 24-hour uninterrupted operation. However, the problem of lunar dust has not been solved. In the simulation test, the sensor probe has been blocked by dust three times."

That night, Lin Dong entered the Chaos Space. He input the particle hardness and buoyancy characteristics of lunar dust into the simulation system, and combined this with modified nanomaterials cultivated from Chaos Beads to develop a "self-cleaning, non-stick coating." This coating's surface can form nanoscale protrusions, causing lunar dust to automatically roll off due to gravitational imbalance. It also possesses radiation resistance and high-temperature resistance. Addressing the problem of barren lunar soil, he optimized the microbial fermentation module of agricultural machinery, creating an "ecological inoculant" from cyanobacteria and nitrogen-fixing microorganisms. This inoculant is planted in the soil along with the seeds during sowing, degrading perchlorate and fixing atmospheric nitrogen to provide nutrients for plant growth.

Three months later, the "Hongxing-110" deep-space breeding agricultural machine completed its adaptation testing at the Jiuquan Satellite Launch Center. The machine adopts a modular design, folding to only one-third of its original size, meeting rocket payload limitations. Its AI terrain response system can autonomously plan paths on the uneven lunar surface, avoiding craters and rock obstacles. Even more impressive is its closed-loop ecological function: plant straw is decomposed by microorganisms into nutrient solution, and wastewater is treated and recycled for irrigation, achieving a water recycling rate of up to 95%.

Just as preparations were underway to launch the cargo spacecraft for the lunar exploration mission, the European Space Agency (ESA) extended a cooperation invitation. They were interested in Hongxing Agricultural Machinery's closed-loop ecological technology and hoped to jointly develop a lunar agricultural base: "Although our MELiSSA project has achieved partial material recycling, its agricultural machinery adaptability is far less mature than your technology." Lin Dong readily agreed, and the two parties reached an agreement: Hongxing Machinery would provide deep-space agricultural machinery and technical support, while ESA would be responsible for launch and lunar base infrastructure construction, jointly creating an "International Lunar Agricultural Experiment Zone."

The news sent shockwaves through the global aerospace community. NASA proactively offered technical exchanges, hoping to introduce the "self-cleaning anti-stick coating" and eco-friendly microbial agent technology; the UAE space agency even signed a direct order, planning to apply the deep-space agricultural machinery technology to a Mars simulation base. Yan Jiecheng once again took the lead, assembling an international technical team to travel to Europe to participate in project coordination, translating the agricultural machinery operation manual into multiple languages ​​including English, French, and German, and optimizing the seed-discharging pressure control of the seeder for the low-gravity environment on the moon, ensuring precise seed placement in the soil.

Domestic applications have also yielded surprising results. The R&D team has "downgraded" and modified the closed-loop ecological technology of deep-space agricultural machinery, launching the "Hongxing-110B" intelligent agricultural machine suitable for mountainous areas. In the hilly citrus orchards of Chongqing, this "mountain version of deep-space agricultural machinery," with its tracked chassis and AI obstacle avoidance system, nimbly navigates between narrow rows of fruit trees, precisely fertilizing and irrigating, and even fermenting fallen leaves and dead branches into organic fertilizer on-site, achieving an ecological cycle in mountain agriculture. Local fruit farmers give it a thumbs up: "In the past, planting fruit trees in the mountains relied entirely on manual labor. Now, the machine is even more meticulous than people, increasing yields by 30% and reducing costs by half!"

That late autumn, the first batch of equipment from the International Lunar Agriculture Experimental Zone was launched into space aboard a cargo spacecraft. At the launch site, Lin Dong, with his middle school-aged son Lin Xiangyang, watched the launch vehicle pierce the sky, their eyes filled with anticipation. Lin Xiangyang, wearing a jacket printed with the words "Hongxing Tuoyu," held a "Mars Planting Concept Diagram" he had designed: "Dad, when I grow up, I'm going to send our agricultural machinery to Mars, so that it'll be full of crops too!"

Lin Dong patted his son on the shoulder, his gaze fixed on the distant starry sky. From small renovations in a traditional courtyard house to agricultural experiments on the moon, from single-machine improvements to global technological cooperation, Hongxing Agricultural Machinery's progress has never stopped. In the laboratory, improvement plans for the dense, oxygen-deficient Martian soil have been launched; in the industrial park, the cultivation of a new generation of radiation-resistant space crops is underway; at overseas bases, technicians from different countries are working side by side to make Chinese agricultural machinery technical standards a global consensus.

As night deepened, the lights of the Red Star Industrial Park shone brightly against the starry sky. Lin Dong knew that the first green sprout on the moon would eventually emerge from the soil under the care of the "Red Star-110" agricultural machinery; and this red star rising from the courtyard would also cross the stars and write a new chapter in human agricultural civilization in the more distant universe.
