Courtyard House: Primordial Chaos Pearl

As the Starship-2 departed Haumea, the pale blue plumes of methane ice volcanoes still shimmered in deep space. This time, its destination was the more distant dwarf planet, Makemake. This celestial body, on which the Soyuz spacecraft has placed high hopes, has a surface temperature of -200°C. Due to the presence of large areas of liquid methane lakes and a more temperate geological environment, it is speculated that it may harbor complex ecosystems. Inside the capsule, symbiotic plant seedlings, acclimatized to the cryogenics of Haumea, are thriving. Ecological monitoring chips transmit data in real time, and the Beacon V7.0's "Multi-Ecological Adaptation" module has been pre-loaded with Makemake's environmental parameters, awaiting the unlocking of new cosmic secrets.

"Distance from Makemake: 1.2 million kilometers. Estimated arrival time: 96 hours." The navigator reported, "Makemake's gravitational field is relatively stable, and there is no significant geological activity in the liquid methane lake area, so the landing risk is low."

Lin Xiangyang stared at the spectral analysis data: "We have detected organic molecules such as methane and ethane in the atmosphere of Makemake, and there are also faint biological fluorescence signals, which most likely come from life activities in the liquid methane lake. The Lighthouse has locked onto the area with the strongest fluorescence as a priority detection point."

Yan Jiecheng inspected the underwater detection equipment: "The improved cryogenic submersible of Chaos Pearl has been debugged and can work normally in liquid methane at -200℃. The high-definition camera and biological sampler on board can capture the morphology of multicellular organisms and collect samples."

He Yushui then summarized the progress of the Earth's Green Veins Project: "The first batch of symbiotic plants has been planted in the pilot desert in Northwest China. Ecological monitoring chips show that the plant roots have penetrated 3 meters into the soil, with a significant sand-fixing effect, soil moisture content increased by 12%, and microbial activity enhanced by 30%. The transformation of saline-alkali land around the courtyard has also started, and the elderly are helping to take care of the seedlings."

On the ninetieth day of the voyage, Makemake finally appeared on the observation screen. It resembled a warm, lustrous piece of jade, its surface dotted with vast expanses of dark blue liquid methane lakes. The edges of these lakes were covered with pale purple crystalline material, and bioluminescence, like scattered diamonds, adorned the surface, shimmering with a dreamlike halo under the starlight. The Starship-2 entered its orbit, and the mapping radar penetrated the lake's surface, transmitting images that astonished everyone:

The lakebed is covered with a soft, carpet-like layer of organisms, which are translucent milky white with fine pores on their surface. They resemble sponges on Earth but can freely expand and contract in liquid methane. Even more surprising is that these organisms have symbiotic bioluminescent microorganisms, which produce the fluorescence, forming a "multicellular organism-microorganism" symbiotic system.

"It's a multicellular organism!" He Yushui exclaimed excitedly. "It has a complex cell structure, exhibits tissue differentiation, and can synthesize organic matter using methane. It's the most complex life form that humans have discovered on distant planets so far!"

A cryogenic submersible descended into the lake and collected samples of multicellular organisms and lake water. Test data showed that the cell walls of these organisms contain special lipids that can resist extreme low temperatures and methane erosion; their secretions are rich in polysaccharides and proteins, which can promote root growth in symbiotic plants and enhance the plants' adaptability to methane environments.

"This is a cosmic gift!" Lin Dong presented sample data at the alliance video conference. "The secretions of multicellular organisms on Makemake can be used as an 'interstellar ecological activator' to build green veins on various planets, especially to improve the survival rate of symbiotic plants in extreme environments."

Just as the exploration of Makemake was making a breakthrough, an emergency alert came from Haumea: "Massive eruption of methane ice volcanoes! The eruption covers 30% of the symbiotic plant growing area, methane concentration has surged, symbiotic plant growth has stopped, and ecological monitoring chips show that leaf chlorophyll content has decreased by 40%!"

He Yushui immediately activated the emergency plan: "The Starship-2, carrying a 'low-temperature cooling module' and an activator made from the secretions of multicellular organisms from Makemake, will be dispatched to Haumea for emergency assistance; at the same time, the ecological control parameters of the lighthouse will be adjusted to guide the Haumea outpost to reduce the light and nutrient supply to the symbiotic plants and reduce metabolic consumption."

The Starship-2 changed course mid-journey and sped towards Haumea. Upon arrival, the cryogenic cooling module rapidly lowered the ambient temperature in the eruption area, inhibiting the diffusion of methane vapor. An activator was sprayed onto the leaves and soil of the symbiotic plants. After 24 hours, monitoring data showed that the plant chlorophyll content began to recover, root activity increased, and the ecosystem gradually stabilized.

Meanwhile, the Earth Green Vein Project has brought good news: the symbiotic plant coverage rate in the pilot desert of Northwest China has reached 20%, forming a large green vegetation belt, and the frequency of sandstorms on the edge of the desert has decreased by 50%; the transformation of saline-alkali land around the courtyard has been successful, and the improved soil can now grow wheat and vegetables. Yi Zhonghai, Liu Haizhong, and Yan Bugui, along with their neighbors, harvested the first batch of "Green Vein Wheat" in the fields. The wheat ears were full and the grains were golden.

"Lin Dong, we did it!" In the video call, Yi Zhonghai held up freshly harvested wheat, his face wrinkled but beaming with a bright smile. "The wheat grown in saline-alkali soil yields even more than before, and it tastes even better! This is all thanks to you!"

Liu Haizhong held up a newly written calligraphy scroll with four powerful characters: "Stars and Earth United." "This calligraphy is for you," he said, "wishing the Earth's Green Vein Project continued success, and wishing the green veins of distant stars eternal vitality!"

Yan Jiecheng's wife held up a plate of freshly steamed buns, still piping hot: "These are made with wheat grown in saline-alkali soil. You can taste the flavors of home even in space! Once the Earth's Green Veins Project is widely implemented, all the deserts and saline-alkali lands across the country can be turned into fertile fields!"

Looking at the familiar courtyard and golden wheat fields on the screen, Lin Xiangyang's eyes welled up with tears: "Grandpa Yi, Grandpa Liu, Grandma Yan, thank you for your contributions. The Earth Green Vein Project has attracted the participation of more than 50 countries around the world. We plan to establish new pilot projects in the Sahara Desert in Africa and the Great Artesian Basin in Australia, so that symbiotic green veins can spread to every corner of the earth."

Beside the liquid methane lakes of Makemake, cryogenic submersibles continue their explorations; symbiotic plants on Haumea are revitalized under the action of activators; Earth's deserts and saline lands are being covered in green, and Starship-2 ships shuttle through interstellar space like a link connecting the stars and the earth.

Standing on the observation platform of the starship, Lin Dong gazed at the bioluminescence on the surface of Lake Bird God and the green veins transmitted from Earth, his heart filled with unwavering certainty. From the improvement of agricultural machinery in traditional courtyard houses to interplanetary ecological networks, from the exploration of life on distant planets to the environmental transformation of Earth, humanity's journey has never been about conquest, but about symbiosis—symbiosis with the universe, symbiosis with nature, and symbiosis with each other.

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

"The light of Bird God Lake teems with life; the green veins of Earth are renewed by stellar technology. The ultimate meaning of interstellar exploration is to let the wisdom of the stars nourish the earth, and let the vitality of the earth reflect the galaxy. May the light of Bird God illuminate a more distant journey, may the green veins of Earth extend to the ends of the universe, and may humanity and nature embark on a covenant of eternal coexistence."

Lin Dong looked at the sentence with anticipation in his eyes. The Alliance has set its sights on Eris, the edge of the solar system, as their next target. There, perhaps, there exist even more extreme environments and more unique life forms, waiting for humanity to discover, protect, and coexist with them.
