Courtyard House: Primordial Chaos Pearl

The Starship-2 navigates the darkness at the edge of the solar system, the pale purple plume of its nuclear fusion reactor the only light in this desolate stellar region. Ahead, Eris emits faint infrared radiation—this dwarf planet, more distant than Pluto, has a surface temperature as low as -240°C, making it the coldest celestial body ever explored by humankind. Its cosmic ray intensity is 1000 times that of Earth, yet the detection of infrared signals suggesting silicon-based life has made it the ultimate challenge of the "Extreme Green Vein Extension Project." Inside the capsule, symbiotic plant seedlings, triple-modified for cold and radiation resistance, grow quietly. The ecological monitoring chip and the "cosmic ray protection" module of the Lighthouse V8.0 work in real time, acting like an invisible shield to protect the life within the capsule.

"Distance from Eris: 1.5 million kilometers. Estimated arrival time: 120 hours." The navigator reported, "The intensity of cosmic rays at the edge of the solar system continues to rise, exceeding the safety threshold. The lighthouse needs to activate enhanced protection mode."

Lin Xiangyang immediately took action: "Lighthouse V8.0 has activated the 'multi-layer protection' strategy—the outer energy shield deflects high-energy particles, the middle rare-earth alloy shell absorbs radiation, and the inner symbiotic plant mucus coating absorbs residual rays. Currently, the radiation intensity inside the cabin is controlled within a safe range, and the ecological cabin parameters are stable."

Yan Jiecheng inspected the extreme cold detection equipment: "The superconducting cryogenic detector improved by Chaos Bead has been debugged and can maintain sensitivity at -240℃. The drill bit adopts 'quantum heating' technology, which can melt the ice layer instantly and avoid low-temperature brittleness."

He Yushui also updated the progress of the Earth's Green Veins Project: "The pilot project in the Sahara Desert of Africa has completed the planting of symbiotic plants on 100 square kilometers. The sand-fixing technology brought by the Chinese team is combined with the local drought resistance experience, and the plant survival rate has reached 85%. There have also been breakthroughs in the transformation of saline-alkali land in the Great Artesian Basin of Australia. Symbiotic plants are mixed with native pasture grasses to form a stable grassland ecosystem."

On the 100th day of the voyage, an unexpected event struck: "Cosmic Ray Storm Warning!" The system alarm blared, "A high-intensity gamma-ray burst is approaching the starship. Estimated contact time: 10 minutes. Its intensity is 5 times that of the previous burst!"

On the observation screen, a dark red cloud of radiation rapidly approached, like a gigantic maw ready to devour everything. These extreme cosmic rays can penetrate ordinary protection, damage biological DNA, and even paralyze electronic devices.

"Activate emergency protection immediately!" Lin Dong decisively ordered. "Adjust the starship's attitude, aligning the thickest protective surface with the direction of the radiation burst; shut down non-essential electronic devices and activate backup power; switch the ecological cabin to 'hibernation mode' to reduce the metabolism of symbiotic plants and minimize radiation damage; face the sun and use the lighthouse's computing power to simulate the radiation burst's trajectory and find weak points to avoid."

Lin Xiangyang's fingers flew across the keyboard, and countless data points flowed rapidly across the screen: "There is a weak 'gap' in the ray burst, only 5 kilometers wide. We can adjust our course to pass through it, but we need to control our attitude precisely, and the error cannot exceed 100 meters."

Yan Jiecheng gripped the control lever: "Leave it to me." The Starship-2's attitude fine-tuning engines ignited continuously, precisely cutting into the narrow safety gap before the cosmic ray storm arrived. Outside, a dark red radiation cloud roared past, and the pale blue halo produced by the collision of the energy shield and the rays illuminated the hull. Inside, the radiation monitoring instrument's pointer jumped violently, but it never exceeded the critical value.

Three days later, the Starship-2 successfully reached Eris's orbit. This icy celestial body, its surface covered with thick methane ice and ice crystals, lacked an atmosphere. Numerous impact craters, like giant footprints, gleamed with a deathly white light under the star's faint illumination. The mapping radar penetrated the ice layer, and the images it transmitted were astonishing:

200 meters below the ice layer lies a huge liquid water cavity. Under the combined effect of the decay heat of radioactive elements and the residual heat of the Earth's core, the water here remains at a liquid state of -10°C. Countless translucent ice crystal-like organisms float in the water. They are hexagonal, like snowflakes on Earth, but they can move slowly in the extremely cold and strong radiation environment. Their bodies shimmer with faint silicon-based fluorescence.

"It's an ice crystal life form!" He Yushui exclaimed excitedly. "Its cell structure doesn't contain carbon; instead, it's based on silicon. The ice crystal layer on its surface can reflect cosmic rays, and the liquid silane inside can store energy. It's a typical prototype of silicon-based life!"

A cryogenic probe submerged into a liquid water cavity and collected samples of the ice crystal organism. The data showed that this organism can convert cosmic rays into energy; its surface ice crystal layer is rich in special silicon compounds, which can significantly enhance the material's resistance to cold and radiation; its metabolic products can promote root growth in symbiotic plants under extremely cold conditions, potentially forming a "silicon-based-carbon-based" cross-species symbiosis.

Just as the exploration was progressing smoothly, the Earth Green Vein Project brought good news of cultural integration: the nomadic people of the Sahara Desert in Africa combined symbiotic plant cultivation with traditional "desert oasis" maintenance experience and invented the "water-following planting method", which moves the planting with the rainy season and increases the speed of green vein extension by 30%; the Aboriginal people of Australia used the ancient "slash-and-burn" technique to improve the soil, which complemented the nitrogen-fixing ability of symbiotic plants and made the saline-alkali land quickly fertile.

"This is the core significance of the Earth's Green Veins Project," Lin Dong remarked at the alliance's video conference. "It's not simply about exporting technology, but a deep integration of culture and technology. The survival wisdom of every nation is a valuable asset for ecological transformation."

The news spread back to the courtyard house, and the Interstellar Agriculture Museum erupted in cheers. Yi Zhonghai, Liu Haizhong, and Yan Bugui, along with a group of students from Africa and Australia, were learning about symbiotic plant cultivation techniques in the fields. The elders explained decades of farming experience from the courtyard house in simple language, while the students shared the ecological wisdom of their respective hometowns.

"Lin Dong, our courtyard house has now become an 'international agricultural school'!" During the video call, Yi Zhonghai beamed. "These foreign kids are learning so diligently! We teach them composting and seed selection, and they teach us to identify drought-resistant plants in the desert. Learning from each other is better than anything else!"

Liu Haizhong held up a calligraphy scroll he had just written, bearing four powerful characters: "Cosmic Coexistence." "This calligraphy is dedicated to all the world's ecological guardians. May the green veins of Earth spread across all five continents, and may the green veins of distant stars extend into the depths of the universe!"

Yan Jiecheng's wife, holding a plate of pastries made from a mixture of African millet and Martian wheat, smiled and said, "This is a 'symbiotic cake' combining Chinese and foreign elements; it tastes delicious. You must try it when you return from Eris!"

Looking at the joyful scene on the screen, Lin Xiangyang felt a surge of warmth in his heart: "Grandpa Yi, Grandpa Liu, Grandma Yan, thank you for your efforts. The ice crystal biological samples from Eris have been collected. Their silicon compound technology will allow green veins to grow in even more extreme environments. When we get back, we'll apply this technology to the Earth's green vein project, so that oases can grow in deserts and polar regions!"

Inside the liquid water cavity of Eris, ice crystal organisms are still moving slowly, their bodies glowing like stars; inside the Starship-2 cabin, symbiotic experiments between symbiotic plants and ice crystal organism samples are underway, and data from the ecological monitoring chip shows that the plants' cold and radiation resistance has increased by 60%; across Earth's continents, green veins are taking root and growing in different cultural soils, forming a magnificent picture of "stars and earth united, coexisting in the universe".

Standing on the observation platform, Lin Dong gazed at the icy surface of Eris and the green images transmitted from Earth, his heart filled with unwavering certainty. From the small side room of a traditional courtyard house to Eris at the edge of the solar system, from the improvement of a piece of agricultural machinery to an ecological network spanning planets and cultures, humanity's path of exploration has always been one of embracing nature with reverence and walking hand in hand with an inclusive spirit.

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

"Eris is frigid, its ice crystals containing silicon; its celestial veins connect the globe, their cultures intertwined. The ultimate answer to interstellar exploration lies not in conquering the vastness of the universe, but in understanding the depth of life; not in cutting-edge technology, but in the connection of hearts. May the light of Eris's ice crystals illuminate the unknown, may the soul of Earth's green veins connect the world, and may humanity and all life together safeguard the safety of the galaxy."

Lin Dong looked at the sentence with longing in his eyes. The Alliance has launched the "Extrasolar Exploration Program," targeting the Earth-like planets of Alpha Centauri, where there may be more mature ecosystems waiting for humanity to discover, protect, and coexist.
