In the mysterious and dangerous core of that turbulent spacetime, Ling Yichen, Jun Mozhan, and their companions remained vigilant even after successfully repairing the "Star Abyss Core." They knew that many obstacles still lay ahead before they could completely escape their predicament and find their way back to their respective timelines. Every step forward felt like trekking through a thicket of thorns, filled with unknowns and challenges, but with unwavering faith, tenacious perseverance, and deep camaraderie and understanding, they steadily moved closer to that hopeful exit.

With the repair of the "Star Abyss Core," the surrounding spacetime turbulence has gradually subsided, but some unstable energy fluctuations remain. These fluctuations, like ghosts lurking in the shadows, occasionally create small spacetime vortexes. Ling Yichen walked at the forefront of the group, carefully sensing the changes in the surrounding energy, gripping a spiritual energy shield tightly in his hand, ready to deal with any unexpected situations. Jun Mo Ran stood beside him, the tip of her wand shimmering with a soft light. That light, like a searchlight, pierced through the slightly chaotic spacetime around them, illuminating the path forward for everyone.

Suddenly, a massive spatial vortex appeared ahead, shimmering with strange light and radiating a powerful suction force. Upon seeing this, Su Ran immediately drew his sword, plunged it into the ground, and chanted incantations. A golden sword aura surged from the blade, rushing towards the vortex in an attempt to counteract some of the suction. Chen Yu swiftly took out his musical instrument and began playing a lively melody. The tune contained unique energy fluctuations that, combined with Su Ran's sword aura, formed a temporary barrier before the vortex.

However, the power of this spacetime vortex far exceeded their expectations. As time passed, cracks began to appear in the barrier, and the suction force grew stronger. Ling Yichen's eyes narrowed, and he turned to Jun Mo Ran, saying, "Mo Ran, let's launch an attack together and try to break through the core of this vortex." Jun Mo Ran nodded in agreement, and the two stood side by side, simultaneously casting spells. Ling Yichen formed hand seals and shouted, unleashing a blazing flame from his hands, which surged towards the vortex like a roaring dragon. Jun Mo Ran waved his wand, and countless ice arrows followed closely behind the flame. The ice arrows and flames fused together, triggering a violent energy explosion within the vortex.

The explosion caused a brief disruption in the spacetime vortex. Lin Shiya seized the opportunity, using magic to create a narrow passage within the vortex. "Quick, everyone follow me!" she shouted. Without hesitation, the group rushed into the passage. Inside, they felt pressure from all directions, as if countless invisible hands were squeezing them. But they supported each other. Ling Yichen and Su Ran led the way, using their own strength to withstand the pressure; Jun Mo Ran and Lin Shiya maintained a magical shield in the middle; and Chen Yu stayed behind, using music to stabilize everyone's emotions and strength.

Having finally traversed the spacetime vortex, they arrived at a strange spacetime labyrinth. The labyrinth's walls were composed of crystals shimmering with various lights, radiating a captivating brilliance while also possessing a bewitching power. Anyone drawn to the light would be trapped in endless illusions.

Ling Yichen was well aware of the dangers involved. He closed his eyes and relied on his powerful spiritual senses to find his way forward. Jun Mo Ran stood to the side, taking out a crystal-clear bead from her bosom. She had obtained this bead by chance during a previous adventure, and it was said to be able to resist the invasion of illusions. She released the power of the bead, enveloping everyone and keeping them conscious.

Within the labyrinth, they encountered phantom monsters formed from spacetime energy. These monsters were ethereal in form, yet their attacks were incredibly fierce. They could traverse spacetime, launching surprise attacks. Su Ran wielded his sword, engaging the phantom monsters in a fierce battle. His swordsmanship was sharp and unpredictable, each strike accurately targeting the monsters' vital points, but the phantom monsters were numerous and constantly regenerating.

Seeing this, Jun Mo Ran and Lin Shi Ya exchanged a glance, then simultaneously cast their spells. Jun Mo Ran's magic transformed into a sea of ​​flowers, the blossoms emitting a captivating fragrance that weakened the phantom monsters. Lin Shi Ya, on the other hand, summoned bolts of lightning that crisscrossed the flower sea, obliterating the phantom monsters weakened by the fragrance.

Chen Yu carefully observed the structure of the maze, noticing a pattern in the light emanating from the crystalline walls. He took out paper and pen from his bookcase and began recording the flashing frequency and color changes of the light. After some research, he finally discovered the maze's pattern. "Everyone, follow me, follow this route," he called out. Following Chen Yu's directions, the group cautiously made their way through the maze, eventually successfully escaping the time-space maze.

At this moment, they sensed the spacetime energy around them becoming increasingly pure, and the exit seemed to be just around the corner. But as they continued forward with hope, a massive spacetime gate appeared before them. The gate was covered with complex runes, emanating an ancient and mysterious aura. Ling Yichen stepped forward, attempting to decipher the runes, but he discovered that these runes were unlike any he had ever seen before; they contained extremely profound spacetime mysteries.

Jun Mo Ran arrived at the door and gently placed her hand on it, attempting to communicate with it using magic. Suddenly, a powerful force emanated from the door, forcing Jun Mo Ran back several steps. Ling Yi Chen quickly supported her, asking with concern, "Mo Ran, are you alright?" Jun Mo Ran shook her head, a resolute glint in her eyes: "This door seems to require specific power to open. We need to work together to find a solution."

The group gathered around the door, discussing how to open it. Chen Yu suggested that the runes might be related to some kind of temporal code, and they needed to find the corresponding code to open the door. So, they began searching the surrounding area for clues. Su Ran discovered an ancient stone tablet nearby, engraved with some blurry patterns that seemed to have some connection to the runes on the door.

Lin Shiya used magic to clearly reveal the patterns on the stone tablet. Chen Yu carefully studied the patterns, combining his understanding of spacetime knowledge with calculations, and finally derived a possible code. Following Chen Yu's deduced code, Ling Yichen channeled his power into the runes on the door. Jun Mo Ran, Su Ran, and Lin Shiya also gathered their power into Ling Yichen, and together they launched an attack.

Under the impact of the immense force, the runes on the door began to flash with dazzling light. As the light flickered, the door slowly opened, and a familiar aura surged out from within. It was the aura of their respective timelines; Ling Yichen sensed the prosperity and tranquility of the Shenghua Dynasty, while Jun Mozhan seemed to see the bustling traffic of the modern world. They knew that after countless hardships and dangers, they had finally overcome numerous obstacles and were approaching the exit, about to return to their own timelines and begin a new chapter.
