At the dawn of the Galaxy Cosmos, a wisp of "Dark Entropy Force" emerged from the dissipation of chaos. It absorbed negative energies across the cosmos, gradually gaining consciousness and proclaiming itself the "Lord of Dark Firmament." Its true form was a swirling mass of dark purple mist, capable of devouring light and disintegrating energy. Most terrifying of all, it could tamper with the "will" of living beings—merely injecting a wisp of Dark Entropy Force into a creature would turn it into a puppet driven solely by destruction.
The Lord of Dark Firmament's ambition was to bring all universes under the "Order of Dark Entropy." It viewed the vitality and order of the Galaxy Cosmos as "superfluous impurities," believing that only when everything returned to the虚无 state of dark entropy could the universe reach its ultimate form. To this end, it built the "Palace of Dark Firmament" in the "Abandoned Cosmic Zone," forging "Dark Entropy Orbs" using the cores of devoured planets. Each orb could contaminate an entire galaxy, slowing time, compressing space, and ultimately turning the galaxy into nourishment for dark entropy.
The first invasion began in the "Glowing Star System." The Lord of Dark Firmament dispatched its "Shadow Legion"—once guardians of planets, now controlled by Dark Entropy Force. These legionnaires snuck into the core of the Glowing Star System with Dark Entropy Orbs. In just three days, thirty planets in the system lost their light, their inhabitants became puppets, and even the stars began to emit a dark purple glow. When news reached the Galaxy Guardians Alliance, Ling Yuan and his comrades felt an unprecedented pressure—they faced no ordinary evil force, but an entity that sought to subvert the very essence of the universe.
The Lord of Dark Firmament's true trump card was the "Cage of Ten Thousand Universes" plan. It collected ninety-nine Dark Entropy Orbs, intending to detonate them at the "Space-Time Hub" of the Galaxy Cosmos. When detonated, the Dark Entropy Force would form a massive net covering the entire universe, trapping all galaxies in a state of dark entropy—even time reversal and space travel would be impossible to break through. To stop this, the guardians split into three teams:
1. Ling Yuan led Yan Feng and Lei Ze to launch a frontal assault on the Palace of Dark Firmament, drawing the Lord of Dark Firmament's attention.
2. Xing Lan and Yue Li headed to the Space-Time Hub, attempting to destroy the Dark Entropy Orbs in advance.
3. Xuan Ying and Qing Mu sneaked into the depths of the Palace of Dark Firmament to find the weakness of the Lord of Dark Firmament's true form.
When the battle erupted, the Lord of Dark Firmament unleashed terrifying power. With a single wave of its hand, it summoned a Dark Entropy Storm. Yan Feng's flames were devoured instantly, and Lei Ze's thunder dissipated into nothingness the moment it touched the storm. Ling Yuan exerted all his strength to unleash the Spiritual Core of Lingyuan Star, barely holding back the storm—only to be surrounded by the Lord of Dark Firmament's puppet army. In this crisis, Xuan Ying suddenly emerged from the shadows behind the Lord of Dark Firmament, stabbing its misty form with a shard of Void Star Crystal. This weakness was discovered by Qing Mu, who, through communication with cosmic plants, learned that although Dark Entropy Force could devour energy, it was extremely sensitive to substances containing "the essence of life."
The Lord of Dark Firmament screamed in pain, its misty form churning violently. Enraged, it struck Xuan Ying with a blast of Dark Entropy Force, sending him flying. But in that brief gap, Xing Lan had already wrapped the Dark Entropy Orbs at the Space-Time Hub with star power, and Yue Li released the power of lunar radiance to purify the dark entropy contamination on the orbs. When the last Dark Entropy Orb was destroyed, the Lord of Dark Firmament's "Cage of Ten Thousand Universes" plan collapsed completely. The Palace of Dark Firmament began to crumble, and the Dark Entropy Force in the Abandoned Cosmic Zone gradually dissipated.
Unwilling to accept defeat, the Lord of Dark Firmament tried to detonate its own Dark Entropy Force, intending to perish together with the Galaxy Cosmos. Seeing this, Ling Yuan immediately united all the guardians, channeling their spiritual power, star power, flame, thunder, lunar radiance, shadow power, and life force into a single "Galaxy Guardian Light Shield." This shield not only withstood the impact of the Dark Entropy explosion but also reversed the effect, purifying part of the Dark Entropy Force within the Lord of Dark Firmament's true form.
In the end, the Lord of Dark Firmament's true form was sealed by the light shield in the rift of the Space-Time Hub. It lost the ability to devour energy, forced to watch as vitality reblossomed across the Galaxy Cosmos from within the rift. The puppets it had controlled gradually regained their consciousness as the Dark Entropy Force dissipated. Standing before the Space-Time Hub, Ling Yuan looked at the Glowing Star System, which had reignited in the distance, and whispered: "The order of the universe is not defined by nothingness, but forged by every spark of vitality and every act of guardianship."
Later, the Galaxy Guardians Alliance established a permanent outpost at the Space-Time Hub. The legend of the Lord of Dark Firmament became a profound warning across the cosmos—never underestimate the power of life and order. No matter how powerful the darkness, as long as the guardians stand together, there will always be light to pierce through the void.
