Ling Yichen stepped forward, a dazzling light erupting from his body, a light like a blazing blade, rushing towards the dark phantom. "We will not allow you to ruin our mission!" he roared. Su Ran followed closely behind, his sword flashing with impenetrable speed, slaying the approaching dark phantoms one by one.

Jun Mo Ran and Lin Shi Ya cast powerful magical shields behind them, enveloping Ling Yi Chen, Su Ran, and Chen Yu. Their shields shimmered brightly under the attack of dark forces, remaining unbreakable despite the immense pressure. Inside the shield, Chen Yu continued playing his instrument; his music penetrated the shield, resonating with the "Star Abyss Core" to ensure the repair work was undisturbed.

In the fierce battle, Ling Yichen and Su Ran gradually became exhausted, but their belief never wavered. They knew that if they gave up, all their previous efforts would be in vain, and the entire spacetime would be plunged into endless darkness and chaos.

Jun Mo Ran felt a pang of pain in her heart as she looked at Ling Yi Chen's exhausted figure. Ignoring the depletion of her own magic power, she resolutely stepped out of her shield and joined the battle. A dazzling chain of magical light appeared in her hand, moving like a nimble dragon, weaving through the horde of dark phantoms and binding them one by one.

Seeing Jun Mo Ran's actions, Lin Shi Ya followed without hesitation. She cast a powerful forbidden magic spell. Although this spell would cause her great harm, she couldn't care less at this critical moment. The light released by the forbidden spell shone like dazzling stars, completely annihilating the dark phantoms.

As the dark forces dissipated, the "Core of the Star Abyss" finally returned to its former peace and stability. The pale blue light radiated evenly and softly, the surrounding spacetime distortions completely disappeared, and everything returned to normal order.

Ling Yichen, Jun Mozhan, and their companions gazed at the restored "Star Abyss Core," their hearts filled with relief and pride. They had successfully undertaken the great mission of restoring the order of spacetime, saving the entire universe with their courage, wisdom, and faith. Their names will forever be etched in the river of time, becoming an immortal legend, inspiring future generations to face difficulties and challenges with unwavering courage and perseverance.
