During the long and arduous search, the teams went through countless hardships and finally brought exciting news one after another: all five sacred objects had been found.

Deep within the metal mine, the first team, after a fierce battle with mutated metal creatures, discovered the Golden Relic was a metallic heart radiating dazzling golden light. It contained pure and powerful metallic energy, seemingly the very soul of the mine. When the team members retrieved it, the entire mine trembled slightly, as if weeping for the loss of this heart.

The second team, navigating through layers of poisonous fog and mutated plants in the heart of the ancient forest, found the sacred wooden artifact—a branch of life radiating a vibrant green light. This branch was teeming with life, each leaf seemingly whispering secrets of the ancient forest. As it was carried away from its original location, the surrounding plants seemed to rejoice, as if knowing it would shoulder the responsibility of saving the world.

In a hidden ice cave in the polar ice field, the third group, after a grueling struggle against an ice-type behemoth, successfully obtained the sacred water artifact—a translucent, azure ice crystal sphere. The sphere seemed to seal within the millennia-old cold and purity of the polar region; it was icy cold to the touch, yet brought a sense of tranquility.

The fourth group, braving the scorching lava and the onslaught of fire spirits in the center of the lava lake at the base of the volcano, found the sacred fire artifact—a Flame Spirit Flower burning with an inextinguishable flame. The flower's petals danced and leaped like flames, releasing enough heat to instantly reduce everything around it to ashes.

In the underground chamber of the desert ruins, the fifth team overcame numerous traps and obstacles, defeated sand monsters, and unearthed a sacred earth artifact—an ancient and heavy stone of the earth. Its surface was covered with mysterious runes, radiating a steady and powerful earth-elemental energy.

When the groups returned to the human settlement with the sacred artifacts, the entire settlement was abuzz with excitement. People saw a glimmer of hope, and their yearning for survival rekindled. With reverence, Su Yao presented the Five Elements Sacred Artifacts to the Yanliang Sacred Qilin.

The Flame-Cool Sacred Qilin gazed at the Five Elements Sacred Objects, its eyes gleaming with excitement. It slowly rose, its body enveloped in a vibrant interplay of flames and cool energy. Following the Qilin's instructions, Su Yao placed the Five Elements Sacred Objects within a specific array.

In an instant, the Five Elements Sacred Artifacts released a dazzling array of colors, which intertwined and converged to form a massive pillar of energy that shot towards the Flame-Cold Sacred Qilin. The Qilin roared to the sky, absorbing this energy infused with the power of the Five Elements. Its body began to change; its scales, which had been somewhat dull due to the seal, regained their dazzling brilliance, and its wounds healed rapidly under the nourishment of this powerful force.

As power was continuously injected, the Flame-Cool Sacred Qilin gradually recovered to its peak strength. It gently waved its claws, and a cool energy wave spread outwards, causing the high-temperature radiation to show signs of weakening wherever it reached.

However, this move also attracted the attention of the remnants of the dark organization. They knew that if the Flame-Cold Sacred Kirin fully recovered its power and helped humanity, they would completely lose their chance to wreak havoc in the high-temperature apocalypse. Therefore, the remnants of the dark organization colluded with some superhumans and mutated creatures whose minds had been warped by the high-temperature apocalypse, forming a huge evil alliance that surged towards human settlements.

Su Yao sensed the enemy's approach. With a determined look, she stood beside the Flame-Cool Holy Qilin. "Qilin Divine Beast, the forces of darkness are attacking. We must fight side by side." The Flame-Cool Holy Qilin nodded in acknowledgment, transferring a portion of its restorative power to Su Yao and her team members, greatly enhancing their abilities.

Su Yao led her team to set up a solid defensive line in front of the settlement. Ling Yu's ice-type ability, enhanced by the power of the Qilin, could instantly freeze large areas; the earth-type ability user could control a giant rock golem, which would stand in front of the enemy like a small mountain; Su Yao used her spatial ability to create spatial mazes to trap the enemy inside. At the same time, she also analyzed the enemy's weaknesses through the system and directed the battle.

The Flame-Cool Holy Qilin charged into the enemy ranks, unleashing alternating bursts of flame and coolness, causing the Dark Alliance to crumble wherever it went. However, the enemy was numerous, including powerful superhumans and mutated creature leaders, and the battle remained deadlocked.

At this critical moment, Su Yao discovered a dark energy tower behind the Dark Alliance, continuously providing them with energy. "We must destroy that energy tower!" Su Yao thought to herself. She selected several elite team members and, using their spatial abilities, quietly slipped through the enemy's lines, heading towards the dark energy tower.

A final battle that will determine the fate of humanity has erupted in front of human settlements. Whether Su Yao and her companions can successfully destroy the Dark Energy Tower, use the power of the Flame and Cold Holy Qilin to completely defeat the Dark Alliance, and save humanity from the apocalypse of high temperatures remains to be seen.
