Having endured this brutal battle, the Cosmic Peace Alliance, while temporarily repelling the dark forces, paid a heavy price. Many planets were ravaged, countless lives perished in the flames of war, and an atmosphere of sorrow and exhaustion permeated the alliance. However, Su Yao knew clearly that there could be no relaxation at this moment; they must quickly rally to prepare for the even more intense retaliation that the dark forces were about to unleash.

Su Yao organized the alliance's research capabilities to conduct in-depth research on the weapons and equipment captured from the battlefield by the dark forces. Through arduous analysis, they discovered that the dark forces had incorporated a new type of dark matter energy source into these weapons. This energy source was not only incredibly powerful but also capable of distorting space and interfering with the normal functioning of supernatural and psychic abilities. To counter this new weapon, the alliance's scientists worked day and night, combining the technological achievements of Earth's civilization with advanced technologies from other civilizations, and finally developed an energy neutralization shield. This shield can effectively resist the invasion of dark matter energy and, to a certain extent, restore the normal effectiveness of supernatural and psychic abilities within its area of ​​influence.

At the same time, Su Yao realized that defense alone could not completely defeat the dark forces. The alliance needed to take the initiative, find the dark forces' stronghold, and uproot them. She led an elite expeditionary force composed of the alliance's bravest warriors, most powerful ability users, and most perceptive psychics on a journey full of unknowns and dangers.

The expeditionary force traversed the universe, gradually approaching the core area of ​​the dark forces, relying on the psionicists' keen sense of the dark aura. However, the dark forces seemed to have already sensed their arrival, setting up numerous traps and powerful fortifications along their inevitable path.

As the expeditionary force entered a mysterious nebula region, they were suddenly encountered by a powerful spatial storm. This storm was not naturally formed, but artificially created by dark forces using dark matter energy. The space within the storm was violently distorted, instantly tearing many warships to shreds and plunging the soldiers into dire straits. Seeing this, Su Yao immediately used her spatial abilities to try and stabilize the surrounding spatial structure. She carved a temporary passage through the storm, allowing some warships and personnel to pass safely for the time being. However, the energy of the spatial storm was too immense, and Su Yao gradually felt overwhelmed.

Just then, Ling Yu led a group of ice-type ability users to step forward. They unleashed their abilities to the fullest, releasing frigid energy that combined with Su Yao's spatial abilities. The cold energy alleviated the spatial distortion to some extent, giving more expeditionary force members a chance to escape the storm's ravages. With everyone's concerted efforts, the expeditionary force finally managed to cross the spatial storm, but suffered heavy losses.

Continuing their journey, the expeditionary force arrived at the core planet of the dark forces. This planet was shrouded in a thick shield of dark energy, surrounded by countless powerful defensive structures and warships. Su Yao knew that a direct assault would inevitably result in massive casualties, so she decided to use her psionic and spatial abilities to find a weak point in the shield and launch a surprise attack.

The psionicists focused their attention, unleashing powerful psionic fluctuations to probe every corner of the shield. After much effort, they finally discovered an anomaly in the shield's energy fluctuations. Su Yao acted decisively, using her spatial abilities to teleport herself and an elite squad to the vicinity of the anomaly. Under the cover of her squad members, Su Yao unleashed her spatial abilities with all her might, attempting to tear open the shield.

However, the dark forces had deployed a large defensive force around the shield, and Su Yao and her companions were met with fierce attacks as soon as they appeared. Dark creatures surged in like a tide, and beams of dark energy shot towards them. Undeterred, the expeditionary force members engaged the enemy in a desperate battle. The superhumans unleashed their unique skills, while the psionicists used their mental powers to disrupt the enemy's movements. The warriors fought valiantly, defending the Alliance's honor with their lives.

In the midst of the fierce battle, Su Yao discovered a crucial control node in the dark forces' defense system. Ignoring the danger, she charged towards the node alone. As she approached, Su Yao was personally intercepted by the dark leader. The dark leader was even more powerful than before; his dark energy burned like black flames, attempting to devour Su Yao.

Su Yao engaged in a breathtaking duel with the Dark Leader. She used her spatial abilities to maneuver against him while simultaneously unleashing mental attacks with her psychic energy. The Dark Leader, equally determined, constantly shifted his attack methods, using dark matter energy to suppress Su Yao. At a crucial moment in the battle, Su Yao recalled the hardships and mission she had undertaken, and an immense surge of power welled up within her. She perfectly fused her spatial and psychic abilities, unleashing an unprecedentedly powerful strike.

This attack struck the Dark Leader squarely in the heart, severely injuring him. Simultaneously, it successfully destroyed a key control node in the Dark Forces' defense system. The Dark Planet's shield instantly developed a massive breach, and the Alliance Expeditionary Force seized this opportunity to launch a full-scale offensive. Warships rained down on the Dark Planet, and the superhumans and warriors charged into the enemy ranks like tigers. After a bloody battle, they finally and completely destroyed the Dark Forces' stronghold.

With the defeat of the dark forces, the Cosmic Peace Alliance ushered in a true glimmer of hope. Civilizations united more closely in this arduous war, working together to rebuild and develop the universe. Su Yao became an eternal hero of the Alliance, her deeds inspiring generations to strive tirelessly to safeguard cosmic peace. In this vast universe, the flame of civilization will continue to burn, shining even brighter, and humanity and other Alliance civilizations will stride confidently towards an unknown yet hopeful future.
