After defeating the mysterious force, Su Yao and the survivor alliance turned their attention to a wider world. The once prosperous land, now ravaged by heat and disaster, needed a comprehensive and in-depth purification and reconstruction.

Using the system's powerful functions, Su Yao conducted a detailed analysis of global environmental data. She discovered that in various corners of the world, there are still many polluted areas and energy turbulence nodes caused by high temperatures. These areas are like malignant tumors on the earth, continuously emitting harmful energy and hindering the revival of life and the reconstruction of civilization.

Thus, Su Yao led the powerful individuals with special abilities and scientific elites from the alliance on a purification journey. They first arrived at the ruins of a city that had once been a major industrial center. Now, the site was shrouded in a thick layer of black smoke, the air thick with a pungent odor, and scalding corrosive liquid flowing across the ground. Su Yao activated the system's detection function, precisely locating the core of the energy turbulence.

She directed the superhumans to unleash their abilities, constructing a massive energy shield that enveloped the contaminated area, preventing the spread of harmful energy. Then, Su Yao retrieved a specially developed purification device from her spatial storage. This device combined the purification power of technology and spiritual plants, capable of absorbing and transforming harmful energy.

During the activation of the device, it was attacked by monsters formed from polluted energy. These monsters were bizarre in appearance, emitted a foul stench, and their attacks were highly corrosive. Su Yao took the lead, using her spatial abilities to nimbly evade the monsters' attacks while simultaneously conjuring a bright purifying light in her hand. This light was a combination of her abilities and the energy of spiritual plants; wherever it touched, the monsters let out painful roars and their bodies gradually dissipated.

Encouraged by Su Yao, the superhumans also exerted their full strength. Some manipulated wind to disperse the black smoke, while others used water abilities to neutralize the corrosive liquid on the ground. After a hard-fought battle and purification effort, the harmful energy of the city ruins was finally cleared, and the sky gradually revealed its long-lost blue.

As the cleanup campaign progressed, more and more land was restored. Su Yao began to contemplate the reshaping of civilization. Utilizing the civilization database within the system and considering the current living environment, she formulated a completely new plan for civilization development.

In education, Su Yao established new-style schools throughout the alliance. These schools not only impart basic cultural knowledge but also focus on cultivating children's abilities to utilize their special powers, their spirit of scientific exploration, and their environmental awareness. She retrieved a large number of precious books, teaching equipment, and intelligent educational robots from her spatial storage, providing the children with excellent learning conditions.

In the agricultural and industrial sectors, Su Yao guided people to develop sustainable production methods. Utilizing the ecological regulation functions of spiritual plants, she cultivated crop varieties more adapted to the post-apocalyptic environment, achieving stable increases in food production. Simultaneously, she led her research team to develop a series of new environmentally friendly industrial technologies. These technologies, powered by clean energy, can efficiently recycle and utilize resources, avoiding secondary pollution to the environment.

However, just as the process of reshaping civilization was proceeding smoothly, Su Yao's system suddenly detected a massive energy fluctuation emanating from the depths of the Earth's core. This fluctuation seemed to foreshadow an unprecedented catastrophe. Su Yao knew that this might be a deeper crisis behind the high-temperature apocalypse.

She quickly convened the core members of the alliance to discuss countermeasures. After in-depth analysis and the collective wisdom of the group, they speculated that this might be related to a disruption of the Earth's internal energy balance. Perhaps the prolonged exposure to high temperatures caused a change in the energy of the Earth's core, triggering a series of chain reactions.

To uncover the truth and avert this potential catastrophe, Su Yao decides to lead an expedition team composed of top-tier superhumans and geological experts to the Earth's core. They travel aboard a specially modified drilling spaceship, slowly making their way towards the Earth's center. Along the way, they encounter the impact of scorching magma, interference from mysterious energy pulses, and attacks from unknown subterranean creatures.

With her powerful abilities and unwavering faith, Su Yao averted crisis after crisis. At a crucial moment nearing the Earth's core, they discovered a massive energy crystal. This crystal emitted a dazzling light, and its energy fluctuations were the source of the crisis. Su Yao attempted to use her system and abilities to connect with the crystal, trying to stabilize its energy.

After a thrilling energy battle, Su Yao finally succeeded in channeling the crystal's energy into an energy conversion device that she and her research team had prepared in advance. This device transformed the crystal's dangerous energy into clean energy usable on Earth's surface, while also restoring the Earth's internal energy balance.

After returning from the Earth's core, Su Yao and the Survivors Alliance continued their great cause of rebuilding civilization. They knew that rebuilding civilization on the ruins of this high-temperature apocalypse was still a long and challenging road, but as long as they united, relying on their wisdom, courage, and Su Yao's system, space, resources, and superpowers, they would surely be able to create a better future and allow human civilization to shine brightly once again on this land that had endured so much hardship.
