Courtyard House: Primordial Chaos Pearl

On the day of the full moon marking the completion of the interstellar symbiosis hub on Blue Star, the light from Alpha Centauri happened to sweep across the crystal fragment at the top of the hub, and pale green energy ripples spread out like waves, connecting with the signals of the interstellar symbiosis network. Inside the hub, the technology taught by the Flowing Light Civilization was being rapidly assimilated by the human team—the base of the interstellar portal had been completed, and the resonant energy of the Chaos Bead and the Earth's core crystal source was continuously being injected into the energy tank of the base; the construction of the first batch of interstellar spaceships was also nearing completion, and the flagship ship, named "Symbiosis," had been covered with a superlattice alloy shell improved by the Chaos Bead, shining brightly in the dock.

Lin Xiangyang stared at the energy calibration data of the portal, his fingertips swiping rapidly across the screen: "The resonant frequency is stable at 99.9% of the Symbiotic Alliance's standard value. After completing the final stress test, the portal will be able to achieve precise jumps within a range of 10 light-years. The Symbiotic's power system has also been debugged, integrating the Chaos Bead's dark matter energy and the space drive technology of the Flowing Light Civilization, achieving a speed of 0.5 times the speed of light."

Yan Jiecheng stood on the bridge of the Symbiosis, directing the robotic arms to install the final energy shield panel. "This ship is the culmination of cooperation between humanity and interstellar civilization." He patted the cold alloy bulkhead, his tone full of pride. "The outer shell can withstand neutron star radiation, and the ecological module is equipped with the most complete symbiotic system on Earth. Even if we drift in a desolate star field for ten years, we can still be self-sufficient."

He Yushui's team was busy with another major project—cultivating an "Interstellar Symbiotic Seed Bank." They sealed Earth's wheat and rice, microorganisms from the subglacial lakes of Pallas, multicellular organism samples from Makemake, and energy plant seeds from Earth into specially made crystal boxes. The surface of the crystal boxes was engraved with a courtyard-style wheat field pattern and incorporated the ripple marks of energy life forms. "These seeds are the sparks of human civilization," He Yushui said, holding a crystal box with solemn eyes. "No matter which star system we fly to, we must sow the seeds of symbiotic hope."

On the eve of the Symbiotic Alliance's near completion and the portal's stress test, Beacon V13.0 suddenly detected three unfamiliar energy signals rapidly approaching Earth from a direction 5 light-years away. The signal frequencies closely matched the Symbiotic Alliance's bands, yet carried a unique crystalline resonance characteristic.

"They're visitors from the Alliance!" Lin Xiangyang quickly decoded the signal, a look of surprise on his face. "They claim to be from the Crystal Clan civilization, from the Proxima Centauri system. They came specifically to communicate after receiving our symbiotic network signal."

On the day the Crystal Clan's spaceships arrived, the sky above Blue Star seemed to be covered with shattered diamonds. Three spaceships, shaped like giant crystals, trailing dazzling crystalline contrails, slowly docked at the symbiotic hub's spaceport. When the hatches opened, what emerged were not energy beings, but a group of life forms completely transparent, their bodies flowing with crystalline liquid—their bones were pale purple crystals, their blood was liquid energy slurry, and as they moved, their bodies shimmered with tiny crystalline lights, creating a fascinating contrast with the energy ripples of Blue Star.

"Greetings, symbiotic beings of Blue Star." The leader of the Crystal Clan was a slender woman whose voice was as clear as the clinking of crystals. "We are the Crystal Clan, home to crystal veins in the universe, and skilled in bio-crystal cultivation techniques. We have heard that Blue Star has established an interstellar symbiotic hub and unlocked the symbiotic code between the Chaos Pearl and the Crystal Source, so we have come here specifically to learn and exchange ideas."

Lin Dong, representing the humans of Blue Star, led the Crystal Clan visitors on a tour of the Symbiotic Hub. When they reached the exhibition area and saw the symbiotic plants that integrated species from multiple planets, and witnessed the harmonious coexistence of energy lifeforms and humans, the Crystal Clan leader's eyes gleamed with astonishment. "We always thought that symbiosis could only exist between crystal veins and energy sources," she remarked. "We never imagined that carbon-based lifeforms, energy lifeforms, and plants could construct such a perfect symbiotic system."

During the exchange, the Crystal Clan brought a precious gift—a "Star Crystal Grass." This grass, rooted in crystal veins, can absorb cosmic rays and produce crystal seeds containing pure energy. It not only enhances the resilience of symbiotic plants but also provides clean energy for interstellar spaceships. "The symbiosis between Star Crystal Grass and Blue Star's energy plants will surely produce unexpected results," the Crystal Clan leader said, handing the Star Crystal Grass seed to He Yushui, his eyes filled with anticipation.

Humanity reciprocated with a special gift from the Crystal Clan—soil from the courtyard house, and symbiotic wheat seeds cultivated within it. "This is the beginning of our civilization," Yi Zhonghai said, leaning on his cane as he walked forward unsteadily. "Back then, we planted wheat in this soil just to fill our stomachs; now, we bring it with us to explore the starry sea so that all civilizations can share the warmth of symbiosis."

The Crystal Clan leader accepted the soil and seeds, her crystalline fingers gently caressing them, a soft ripple spreading through the crystalline essence within her. "This gift is more precious than any energy crystal," she said solemnly, carefully placing the soil and seeds into the crystal box. "We will take it back to Proxima Centauri and plant it in our crystalline home, so that the fragrance of wheat from Blue Star may permeate the cosmos."

During their time together, the Crystal Clan and humans sparked countless innovations through technological collaboration. Together, they improved the Symbiosis's energy system, using Star Crystal Grass seeds as auxiliary fuel to triple the ship's endurance. They also jointly developed the "Crystal Energy Symbiosis Shield," which combines crystal energy with the energy ripples of Earth to protect against various risks during interstellar travel.

The pressure test of the portal was also successfully completed. When the blue light of the Chaos Pearl and the green light of the Earth's core crystal source were simultaneously injected into the base, a pale green light gate with a diameter of 100 meters burst open, and on the other side of the gate, the brilliant star map of the Vega Galaxy was clearly reflected.

On the day the Symbiosis was completed, all the residents of Blue Star gathered at the spaceport. The elderly people from the courtyard held the crystal box of the interstellar symbiosis seed vault and personally sent it onto the spaceship; the four characters "Star River Symbiosis" written by Liu Haizhong were engraved on the bow of the Symbiosis; Yi Zhonghai gave Lin Xiangyang a sickle he brought from the courtyard.

"Take it to the stars." The old man's voice was hoarse but firm. "I used it to harvest wheat back then, and I will use it to harvest the hope of the universe in the future."

Lin Xiangyang took the sickle, his eyes slightly red. He turned and climbed onto the bridge of the Symbiosis, where Lin Dong, Yan Jiecheng, He Yushui, and two Crystal Clan advisors were already waiting.

"Symbiosis, set sail!"

With Lin Xiangyang's command, the Symbiotic Ship slowly departed the spaceport, its pale green energy flames merging with the light of the interstellar portal. The moment the ship passed through the portal, a thunderous roar of cheers erupted across the sky above Blue Star.

On the observation platform of the hub, Yi Zhonghai, Liu Haizhong, and Yan Bugui exchanged a smile as they watched the light gradually disappear through the teleportation portal. Behind them, the seeds of Star Crystal Grass had already sprouted in the soil of Blue Star, and the pale purple crystalline sprouts were wrapped with energy ripples from Blue Star.

Lin Xiangyang stood by the porthole on the bridge, gripping the sickle from the courtyard house, gazing at the sea of ​​stars rushing past outside. He opened the lighthouse log and wrote a new line:

"The Symbiosis Ship sails through the cosmos, the Crystal Clan, sharing a common origin, speaks of symbiosis. From the wheat fields of the courtyard to the interstellar routes, humanity's footsteps have never ceased. May this journey allow the seeds of symbiosis to take root and sprout in every corner of the universe."

On the radar screen of the Symbiotic Spacecraft, the lights in the Vega system grew brighter and brighter; the home of the Flowing Light Civilization was now close at hand. And in the far reaches of the cosmos, countless lights from Alliance civilizations awaited their encounter with Earth.
