After Su Yao successfully stabilized the energy core of the ruins, the high temperature eased somewhat, but it did not completely dissipate. The land remained cracked and barren, water was scarce, food was difficult to grow, and new crises followed one after another.

Following the system's prompts, Su Yao learned that deep within the remote desert lay a mysterious oasis that might harbor abundant water. This ancient water source, hidden within a special spatial rift before the apocalyptic heatwave, could greatly improve her current situation if it could be activated and utilized. However, the path to it was heavily blocked by raging sandstorms and mutated sand beasts.

Su Yao led her intensively trained team on a resolute departure. They rode in reinforced sand trucks, the wind howling outside and visibility extremely low. Su Yao used her special ability to sense the road ahead, directing the vehicle forward with great difficulty. Suddenly, a mutated sand beast, as large as a mountain, burst forth from the sandstorm. Its body was covered in scales as hard as iron, and every movement caused the earth to shake violently.

Su Yao swiftly ordered her team to form a defensive formation, then leaped into the air, her hands flashing as her supernatural energy coalesced into a dazzling blade of light, which she slashed fiercely at the sand beast. The sand beast, however, shattered the blade with a single swing of its massive claws, demonstrating astonishing power. The team members unleashed their energy weapons, attacking the sand beast's vulnerable spots, such as its eyes. Taking advantage of the situation, Su Yao used her spatial confinement ability to temporarily restrict the sand beast's movements, then concentrated her full power in a final strike, finally leaving a deep wound on the beast. The sand beast, in pain and furious roar, struggled even more frantically.

After a thrilling and grueling battle, they narrowly defeated the sand beasts and continued their journey towards the oasis. As they approached the legendary oasis region, they discovered a faint spatial barrier. Su Yao focused her mind, working with the system to analyze the barrier's mysteries. After several hours of effort, she discovered that the barrier required a specific energy frequency to activate, and this frequency was related to her special ability.

Su Yao adjusted her special ability to a specific frequency and slowly channeled it into the barrier. The barrier began to shimmer with a strange light, and gradually an entrance appeared. The group stepped inside with anticipation, and a lush scene unfolded before their eyes: a clear lake shimmered in the sunlight, surrounded by shady trees, and various rare pre-apocalyptic plants. Su Yao immediately directed her team to set up collection devices, retrieve containers from their spatial storage to store water, and collect seeds and fruits from cultivable plants.

But their idyllic state was short-lived. This oasis seemed to be the territory of some mysterious creature. A group of guardian beings, resembling elves yet exuding a dangerous aura, appeared and attacked Su Yao and her companions for their "invasion." These guardian beings were agile and could manipulate the power of natural elements; in an instant, a fierce wind arose, and branches and vines shot towards the group like sharp arrows.

Su Yao activated the system's defense enhancement function and simultaneously released her special ability to form a protective shield around the team. Knowing that she couldn't rely solely on defense, she took the initiative, using her spatial ability to teleport behind the guardian creatures and unleash a powerful mental shock to disrupt their movements and attack rhythm. The team members also cooperated seamlessly, using energy weapons to maneuver around the guardian creatures.

During the fierce battle, Su Yao discovered a psychic bond among the guardian creatures, allowing them to share information and power. She decisively changed her strategy, focusing her energy on severing this bond with her special abilities, plunging the guardian creatures into brief chaos. The team seized the opportunity, launched a final assault, and successfully repelled the guardian creatures.

Su Yao and her companions returned to the shelter with precious resources. With ample water and new plant seeds, the shelter launched a large-scale planting and breeding program, and people's lives gradually improved. Su Yao also used natural energy elements obtained from the oasis, combined with system technology, to upgrade the shelter's energy system, further improving the living environment and giving people more hope for survival and development in this high-temperature apocalypse. They continued to steadfastly search for life in the face of adversity and pursue the light of rebirth.
