As the alliance was established and developed, Su Yao discovered clues about a mysterious ruin in the ancient documents of the settlement. It was said that the ruin held the root of the high-temperature apocalypse and the ultimate power that could completely change the current situation. Despite the numerous dangers, Su Yao decided to lead an elite team to explore it further.

This team includes Ling Yu, several partners skilled in different supernatural abilities, and top researchers from the settlement. Following historical records, they trekked a long way to the depths of a desert whose landscape had been distorted by intense heat. The air here seemed to be on fire, and columns of molten lava erupted from the ground from time to time.

Finally, they found the entrance to the ruins. It was a massive stone door, covered in ancient and mysterious runes, emitting a faint glow. Su Yao tried to use her spatial abilities to sense what was behind the stone door, but discovered that a powerful force was interfering with her detection.

"This stone gate is not simple, everyone be careful," Su Yao warned.

Researchers began scanning and analyzing the stone door, attempting to find a way to open it. Meanwhile, Ling Yu and the other superhumans vigilantly guarded the surrounding area, wary of any potential dangers.

After some effort, the researchers discovered that these runes seemed to require a specific energy frequency to activate. Su Yao mobilized her supernatural abilities and, according to the frequency calculated by the researchers, slowly injected energy into the runes.

As energy was injected, the stone door slowly opened, and an ancient and powerful aura rushed out. Inside was a long passage, with glowing crystals embedded in the walls, illuminating the path ahead.

They cautiously ventured deeper into the passage, discovering numerous ancient technological devices and strange biological specimens along the way. These specimens all exhibited characteristics of mutation caused by high temperatures, seemingly telling tales of a terrifying apocalyptic world ravaged by heat.

Suddenly, a sharp alarm blared through the passageway. Immediately afterward, a swarm of mechanical golems emerged from all directions. These golems were tall, entirely made of metal, with red-glowing eyes, and wielded various weapons.

"Prepare for battle!" Ling Yu shouted, charging towards the swarm of mechanical puppets. He unleashed his ice-based abilities at full power, continuously firing ice blades and ice spears at the puppets, attempting to freeze their movements.

Other ability users also unleashed their powers. The fire ability user wrapped flames around the puppets, attempting to burn away their internal circuitry; the earth ability user summoned a giant rock fist and smashed it at the puppets; Su Yao used her spatial abilities to disrupt the puppets' attack trajectories and redirect their weapons elsewhere.

However, these mechanical golems possessed extremely strong defenses. They quickly recovered after being attacked and continued their fierce assault. Moreover, they seemed to possess some kind of intelligence, coordinating with each other to form an attack formation.

Su Yao realized that this couldn't go on. She activated the system, trying to find the mechanical puppet's weakness. After a quick analysis, the system indicated: "The mechanical puppet's core energy source is located in its chest area; destroying the core energy source will paralyze it."

Su Yao relayed this information to everyone. As a result, the group changed tactics and began focusing their firepower on the mechanical puppets' chests. Su Yao used a spatial rift to appear directly beside the puppets and then used her spatial ability weapon to pierce their core chests.

With everyone working together, the horde of mechanical golems was gradually wiped out. However, they also paid a heavy price, with several of their companions injured.

Su Yao led her team deeper into the ruins. They arrived at a huge hall, in the center of which was a massive energy sphere, seemingly containing countless secrets.

As they approached the energy sphere, a virtual image appeared before them. The image depicted an ancient sage who slowly spoke: "You have come here to uncover the truth behind the high-temperature apocalypse. The root of all this is an out-of-control experiment. This energy sphere is the key to controlling the high temperatures, but activating it requires a tremendous price. Are you willing?"

Su Yao stared at the energy sphere, deep in thought. Activating it might pose unknown dangers, but if successful, it could save the entire apocalypse. She gritted her teeth and said, "We're willing to try."

The image of the sage nodded and then began to explain how to activate the energy sphere. Following the sage's instructions, Su Yao and the others began preparing for the activation ceremony. They slowly channeled their supernatural energy into the energy sphere, while researchers operated ancient technological devices to guide the energy flow.

As energy was injected, the energy sphere began to tremble violently, and the surrounding space distorted. Su Yao felt a powerful force pulling at her soul, but she gritted her teeth and persevered.

Just as the energy was about to be fully charged, the ruins suddenly trembled violently, as if they were about to collapse. Outside, a terrifying roar came from within, as if a powerful beast had sensed the anomaly within the ruins and was rushing over.

Su Yao faced a difficult choice: continue activating the energy ball or give up on escaping? But she quickly strengthened her resolve and shouted to her companions, "Hold on, we must succeed!"
