A Galaxy of Interwoven Defenses

In the third month of stable collaboration between the old and new defense lines in the Rainbow Meadow, "glowing veins" grew on the sixth annual ring of the Twin-Realm Tree. These veins, like "miniature defense line trajectories," sometimes "overlapped" with the Symbiosis Mark of the old ones, and sometimes "intersected" with the tender patterns of the new buds, eventually converging at the center of the annual ring into "a miniature galaxy"—with "countless points of light" floating in the river, each point of light representing "a successful collaborative protection," shimmering with "the old's composure" and "the new's agility."

The transparent tree of the seed absorbed this galaxy into the Memory Light Stone, and its trunk and intertwined branches with the Twin-Realm Tree began to "grow along the veins." The Time Fruit on the branches became "semi-transparent," revealing "the patterns of interwoven old and new energies" within the flesh: the old energy was like a "steady river," and the new energy was like a "leaping stream," eventually converging to nourish "the kernel with a double luster." "Cooperation is not 'who follows whom,' but 'water flows into a river, streams converge into a sea.'" The roots of the transparent tree "extended outward" along the trajectory of the defense line, weaving "a wider net of light" in the void. The nodes of the net contained both "coordinates of the Symbiosis Mark of the old existence" and "tender patterns of the new buds," like a "star map marking the positions of all guardians."

In Luoyu's diary, the interwoven defenses are depicted "like a dynamic tapestry." She uses silver threads to draw the defenses of the old, existing ones, and gold threads to draw the defenses of the new sprouts. The two lines are "sometimes parallel, sometimes intersecting" on the paper, and at the intersections, "small points of light automatically emerge"—those are moments of coordinated protection. She draws a time when dealing with Void Spores, where the large spiral of the Light Vortex "encircles most of the spores," while the small tent of the Vortex Sprout "precisely catches the few that slip through." She draws a time when Angular Nebula "blocks the most powerful impact," while the small wall of the Angular Sprout "cleans up the remaining fine sand." Most ingeniously, the light filament ring of the Shadow Sprout and the fragments of the Old Shadow "form a filter layer," which can both "block impurities" and "let sunlight pass through."

"They are like two complementary umbrellas, one to withstand the wind, the other to shield from the rain." Beside the brocade painting, she wrote the same sentence with two different colored pens, "Our defense line is a miracle where 1 plus 1 is greater than 2." The words written with silver thread were steady, while those written with gold thread were lively, yet they "perfectly overlapped" at the end.

In Qingxian's harmonious symphony, the "flowing sound of the Milky Way" is added. She makes the piano music imitate the "fusion of old river and new stream": the old melody is like a "low-lying riverbed," supporting the new melody as it "flows lightly"; when the new melody encounters a "rapid rhythm," the old melody will "immediately slow down, supporting its rise and fall"; when the old melody "becomes calm," the new melody will "jump out lively notes, injecting vitality into it." As the movement begins, the Milky Way in the rings of the Twin-Realm Tree suddenly "flows along the light network," transmitting the energy of the old and new defense lines "to every node," allowing even the outermost Shadow Sprout to "feel the power of the Light Vortex," and allowing even the core Angular Nebula to "touch the dynamism of the Angular Sprout."

"In harmonious music, there is no 'protagonist,' only 'harmony.'" Qingxian looked at the light network, where old and new energies "alternated like breathing," and suddenly understood the true meaning of the defense line: it's not about "who protects whom," but about "each becoming the other's support," allowing the power of solitude to "form an unbreakable net."

Beside Yanche's symbiotic wooden plaque, a "Defense Line Honor Wall" has been erected. The Star Core Stone on the wall record "details of each collaboration": "17th defense, 92% coordination between the old and new defense lines, 0.3% of spores slipped through the net"; "42nd defense, energy consumption reduced by 60% compared to individual defense"; "89th response, the new sprouts proactively adjusted the angle of the defense line, reducing the pressure on the old beings by 30%." But the most striking thing is not the data, but the "handprints" on the edge of the stone slabs— the Symbiosis Mark markings of the old beings and the tender markings of the new sprouts "overlapping" together, like countless "clenched hands."

"Honor isn't about 'who did better,' it's about 'we did very well.'" Yanche watched as the Light Vortex and Vortex Sprout compared their marks before the wall of honor, their spiral bodies and the light beads reflecting each other's light. He planted "Circle Coordination Grass" at the foot of the wall, the grass leaves swaying simultaneously with the energy fluctuations of the old and new defense lines. "Even the grass is learning our tacit understanding."

In the Star Orbit Root Network's logic log, the "cooperative algorithm" has been upgraded to a "Symbiotic Neural Network." This network no longer relies on "preset instructions," but instead allows the energy of the old and new to "freely exchange data": Star Orbit Rune will pass on their "experience in dealing with turbulence" to Angular Sprout, while Angular Sprout will feed back "newly discovered energy buffer angles" to Star Orbit; Light Vortex and Vortex Sprout share the "optimal spiral angle for capturing stardust," and Old Shadow and Shadow Sprout exchange the "latest frequency of filament connections." On the blank pages of the log, the new runes have drawn an "energy cycle diagram," which has no "starting point and ending point," only "infinitely looping arrows," labeled. "The best cooperation is when energy 'comes alive' between each other."

Late that night, a sudden, intense energy surge emanated from the void—more powerful and rapid than ever before. The old and new defenses remained calm. The runes of the Star Orbit Root Network were the first to calculate the impact angle. The old beings' defenses contracted inward by 0.3 light-years, forming a solid core; the new beings' defenses expanded outward by 0.5 light-years, creating a flexible outer layer. When the impact arrived, the outer layer of new beings acted like elastic cushions, first weakening the energy's sharpness; the inner layer of old beings acted like sturdy shields, blocking the remaining impact force. The two worked together seamlessly.

After the impact, the defenses remained intact, and the galaxy within the rings of the Twin-Realm Tree suddenly "expanded," with countless new points of light "joining in," making the galaxy "even more dazzling." The spiral of the Light Vortex gently touched the light orb of the Vortex Sprout, "You did better than I did the first time"; the Angular Nebula rubbed its armor against the fragment of the Angular Sprout, "The pressure was just right"; the fragment of the Old Shadow and the light filament ring of the Shadow Sprout "clutched tightly," needing no words, yet understanding each other's "pride."

The Boundless Wind swept through the surging galaxy, carrying the energy of collaboration, towards "all worlds that need to stand shoulder to shoulder." Hidden within the wind was the wisdom of interwoven defenses, the secrets of energy cycles, and the Root Language inscribed atop the wall of honor:

"So-called collaboration means that the old are generous with their experience, and the new are not afraid to try; it means that you understand my composure, and I understand your agility; it means that defenses intertwine into a galaxy, and agreements are woven into a net of light, so that we can support each other and write a longer and brighter story of protection."

Meanwhile, the old and new defense lines continue to "optimize and coordinate," the Milky Way "flows wider and wider" in the rings of time, and the light network "weaves denser and denser" in the void; the handprints on the wall of honor "increase and increase," and the leaves of the Coordination Grass "become more and more lush." The guardianship of the Root Network Sea of Stars, in the tacit understanding of the old and new working side by side, has become "an unending symphony," with every note saying, "Together, we fear no storm."

Just like the drawing on the latest page of Luoyu's diary: in the night sky, the light of the old and new defense lines intertwine to form a "giant constellation", the shape of which is "a circle without gaps", and in the center of the circle, the annual rings of the Twin-Realm Tree are "constantly gushing out galaxies" -- that is the miracle of the intertwined defense lines, the eternity woven by the agreement.

The wind continues to blow, the Milky Way continues to flow, the optical network continues to weave, and the collaborative protection of the Root Network Sea of Stars, with the old and the new standing side by side, is heading towards a more vast distance.
