The powerful consciousness emanating from the "Heart of the Frost Source" surged through Su Yao and Ling Yu's minds like a tidal wave. They instantly experienced countless images of coldness and loneliness, as if they were in the icy world at the beginning of the universe.

"Is this... it showing us its memories?" Ling Yu said, enduring his headache. Su Yao gritted her teeth, trying to stay awake. Her system was rapidly analyzing the information being transmitted by this consciousness, attempting to find a way to deal with it.

In the scene, the "Heart of the Frost" was originally the guardian of the world's balance, its power maintaining climate stability. However, an unknown disaster shattered this balance, and a large amount of negative energy poured in, polluting the "Heart of the Frost" and leading to the arrival of the apocalyptic extreme cold.

"It wants us to purify it," Su Yao concluded through system analysis. But purification would come at a huge cost; they would have to inject their special abilities and life energy into the "Heart of the Cold Source" to have any chance of survival.

“We have no other choice.” Ling Yu’s eyes were firm. He took the lead and walked towards the “Heart of the Frost Origin”, placing his hand on the ice crystal. His ice-type power began to flow in continuously, and a layer of blue light emanated from his body.

Su Yao looked at Ling Yu and placed her hand on his without hesitation. She activated her spatial ability, transmitting her energy through a special spatial channel. At the same time, her system was also providing full assistance, adjusting and stabilizing the energy output.

As energy was injected, the light of the "Heart of the Frost Source" flickered, and that powerful consciousness returned, this time as an emotion of pain and struggle. Their bodies began to bear an immense burden; the cold seeped into them from within, every inch of their skin feeling as if it were being pierced by a thousand needles.

"Hold on!" Su Yao shouted, feeling her consciousness fading, but her inner belief sustained her. Their life energy was constantly draining away, and their bodies were growing weaker and weaker.

Just as they were about to run out of energy, the "Heart of the Frost" suddenly unleashed a powerful suction force, drawing away all their remaining energy. Everything went black before their eyes, as if their souls had been ripped away.

After an unknown amount of time, Su Yao slowly awoke to find herself in a strange space. It was a vast, white world with no upper or lower boundaries, surrounded by flowing energy light.

"Where is this?" Su Yao's voice echoed through the space. Suddenly, she saw Ling Yu's figure, who also looked bewildered. At this moment, the consciousness of the "Heart of the Cold Source" reappeared, this time much gentler.

It told them that this was its core space, and their sacrifice had successfully activated the purification process. But the purification still required a ritual: finding three hidden energy keys in this space to open the door to the purification core.

Su Yao and Ling Yu began their search in this strange space. The space seemed infinite, and they could only explore it using their senses and the fluctuations of their special abilities. Su Yao used her spatial abilities to traverse different areas, while the system continuously scanned for energy anomalies.

Finally, at the center of an energy vortex, Su Yao found the first energy key. This key was like flowing light, and holding it in her hand, she could feel a warm power.

Ling Yu continued his search and found the second key in an area composed of energy threads. This key resembled an ice sculpture, exuding an aura of coldness and purity.

With two keys in hand, they became even more eager to find the third. After a difficult search, they discovered the third key within a seemingly ordinary white energy cluster. This key was golden, with intricate patterns representing balance and order.

They arrived at a massive portal of light, carrying three keys, and inserted them into their corresponding slots. The portal slowly opened, revealing a purification core radiating dazzling light. They knew the final challenge lay ahead: to completely purify the "Heart of the Frost Source" and restore life to the world.
