Courtyard House: Primordial Chaos Pearl

Before the ink of the interdimensional symbiosis covenant had even dried, a pale green energy network, centered on the super symbiotic star, spread outwards to all dimensions of the universe. At the nodes of the network, fragments of the Chaos Pearl intertwined with the energy of the Origin Pearl, transforming into interdimensional portals that tightly linked together the light and shadow civilizations of parallel universes, the ancestral star civilization of the Milky Way's center, the binary star civilization of the solar system, and the nascent civilizations at the edge of the universe.

On the day the portal opened, countless spaceships traversed between dimensions. The Lightwing Ships of the Light and Shadow Civilization brought interdimensional energy conversion technology, capable of converting stellar radiation from different universes into symbiotic energy; the Seeding Ships of the New Civilization were laden with improved Star Wheat seeds, sowing life on barren planets in various dimensions; and the agricultural teams of Earth and Blue Star, armed with hoes and sickles from traditional courtyard houses, cultivated the first batch of interdimensional symbiotic wheat on the fertile soil of a parallel universe.

The myriad-star symbiotic tree on the super symbiotic star, nourished by interdimensional energy, grows ever more luxuriantly. The patterns on its trunk extend to every node of the dimensional light network, each leaf shimmers with starlight from different universes, and each fruit embodies the wisdom of different civilizations. The three elders, Yi Zhonghai, Liu Haizhong, and Yan Bugui, simply built a thatched hut next to the tree, brewing star barley tea every day to entertain visitors from all dimensions.

"After drinking this cup of tea, we'll be a family across dimensions!" Yi Zhonghai tapped his pipe, causing the messengers of the Light and Shadow Civilization to nod repeatedly—though they had no physical form, they could feel the symbiotic warmth in the tea.

Just as the interdimensional symbiotic network was flourishing, a violent energy signal suddenly tore apart the edge of the dimensional light network. The signal carried an aura of destruction, with a frequency identical to that of the Star-Eating Civilization of yesteryear, yet even more violent—it was the Shadow Civilization, predators from the dark dimension, who lived by devouring the symbiotic energy of different universes.

The alarm instantly resounded across all the symbiotic planets in every dimension. The Shadow Civilization's warships were entirely black, their hulls covered with dark patterns that could absorb energy. Like a swarm of locusts, they swept across the nodes of the dimensional light network. Wherever they went, portals collapsed, symbiotic plants withered, and even the branches and leaves of the myriad-star symbiotic tree began to turn yellow.

"The Shadow Civilization's target is the Origin Pearl!" the guardian of the Super Symbiotic Star shouted anxiously. "They want to devour the Origin Pearl's energy and become the overlords of this interdimensional world!"

The alliance urgently activated its cross-dimensional defense line. Lin Dong infused the Chaos Pearl's energy into the dimensional light network, and a pale green light instantly enveloped all nodes; the Crystal Clan's star crystal turrets rose into the air simultaneously, and pale purple beams of light pierced through the dimensional barriers, accurately hitting the shadow warship's dark patterns; the Mushroom Clan's guiding spores transformed into a sky full of spore clouds, forming a protective layer in the dimensional rifts to prevent the shadow warship's invasion; the Light and Shadow Civilization's light-winged ships unfolded spatial folds, trapping the shadow warship in the dimensional rift.

Lin Xiangyang piloted the upgraded Symbiosis, leading the Starship Fleet towards the battlefield. The four large characters "Star River Symbiosis" on the bow of the ship, empowered by the dual energies of the Chaos Pearl and the Origin Pearl, burst forth with dazzling light. The Symbiosis's star crystal shield could absorb the dark energy of the Shadow Warship, and its weapon system, modified by the Star Wheat Seed, could fire beams imbued with symbiotic energy. Each beam shattered the Shadow Warship's dark patterns.

He Yushui and her ecological team stood guard beside the Myriad Star Symbiotic Tree. She infused the tree's roots with the energy of the Origin Pearl and buried the seeds of various civilizations in the soil. Instantly, the tree's branches and leaves came back to life, and pale green energy ripples spread out, repairing the cracks in the dimensional light network. The symbiotic plants that had withered due to the Shadow Civilization sprouted new buds under the nourishment of the ripples.

On the battlefield, the Alliance fleet engaged in a fierce battle with the Shadow Civilization. Earth's farmers piloted agricultural mechs, using modified hoes to shatter the hulls of Shadow warships; Blue Star's energy lifeforms transformed into ribbons of light, entangling the Shadow warships and stripping them of their dark energy; warriors of the nascent civilization, piloting seed-planting ships, planted symbiotic seeds on the wreckage of the Shadow warships—they had once strayed onto the path of plunder, but now, they would use the power of symbiosis to protect the order of the universe.

The battle lasted three days and three nights. When Lin Dong fully fused the energy of the Chaos Pearl and the Origin Pearl, a pillar of light piercing through all dimensions shot into the sky, and the Shadow Civilization's flagship finally collapsed with a deafening roar. The fleeing remnants of the ships were trapped in the dimensional rifts by the Light and Shadow Civilization's light-winged ships, and could no longer wreak havoc.

The cracks in the dimensional light network gradually healed, the symbiotic tree of myriad stars flourished again, and the symbiotic planets in various dimensions returned to their former peace.

At the victory banquet, envoys from various civilizations gathered beneath the Myriad Stars Symbiosis Tree. The envoy of the Light and Shadow Civilization presented Lin Dong with a Light and Shadow Crystal, which could enhance the Chaos Pearl's cross-dimensional resonance ability; the Crystal Clan leader forged a Star Crystal Stele, engraved with the names of all participating civilizations; Yi Zhonghai hung the sickle from the courtyard house on a branch of the Myriad Stars Symbiosis Tree—this sickle had once harvested wheat from Earth, star wheat from the Moon, and red soil wheat from Mars; now, it had become a symbol of cross-dimensional symbiosis.

Lin Xiangyang opened the Lighthouse Log and wrote a new line next to the Interdimensional Symbiosis Convention:

"The transdimensional network connects thousands of universes, and fleeting shadows can cause calamities, but the banner of symbiosis will forever fly in the winds of the universe."

At that moment, a brand new fruit suddenly sprouted at the top of the Myriad Stars Symbiotic Tree. The fruit was completely transparent, containing countless microcosms of the universe within. The guardian excitedly told everyone that this was the Interdimensional Symbiotic Fruit; eating it would allow one to resonate with civilizations across all dimensions.

Lin Dong picked the fruit, divided it into countless portions, and distributed them to each of the envoys present.

As the sweet taste of the fruit spread in their mouths, everyone felt it—heartbeats from different universes resonating in unison.
