As humanity continues to explore the depths of the Earth in search of livable space, a heart-shaking adventure is inadvertently uncovered. On a blustery evening, the Earth's core research team's drilling machine unexpectedly breaks through the rock layer, and a strange light emerges from the depths.

The rock, once thought to be solid, seemed to become transparent under the illumination of this light. Dr. Li, the leader of the research team, stared in disbelief at the scene before him. Beneath the solid rock lay not the lava or deeper layers of rock that one would have expected, but a layer of glittering, translucent crystals, layered one upon another, like palaces constructed of crystal.

"This... How is this possible?" Dr. Li muttered to himself, his heart filled with shock. They carefully operated the drilling machine, attempting to explore this mysterious second underground world. As the drill went deeper, more and more crystals appeared before their eyes, shimmering with a soft light, illuminating the entire space with a dreamlike atmosphere.

The crystals seemed to harbor a hint of life. Dr. Li and his team, donning specialized protective gear, decided to explore for themselves. Passing through a crystal archway, they saw a vast and mysterious crystal world unfold before them.

The crystals here take on various shapes: some resemble towering ancient trees, some resemble soaring phoenixes, and still others stand like silent guardians on the crystal land. A light fragrance permeates the air, bringing peace and tranquility to the mind.

Dr. Li and his team traveled through this crystal world, constantly discovering new wonders. They saw transparent creatures moving among the crystals. They had no physical form, but emitted a faint glow, as if they were born from the crystal itself.

As they explored deeper, they discovered a vast crystal palace. Each crystal in the palace was intricately carved with patterns, telling ancient and mysterious stories. Dr. Li led the team through the palace, hoping to find clues to this subterranean world.

However, when they touched a huge crystal in the center of the palace, the entire crystal world suddenly began to shake. They realized that this crystal seemed to be the core of this world, maintaining the balance of the entire underground world.

Dr. Li and his team decided to stop exploring further to avoid disrupting the harmony of this world. They left this mysterious crystal world with full of wonder and awe, and kept this adventure deep in their hearts.

After returning to the surface, they recorded their experience and decided to keep this secret forever in the history of mankind. And that mysterious crystal world also became an eternal legend in their hearts.

The team members were all captivated by this mysterious and beautiful sight. However, Xiao Yi was different. He gazed at the crystals, his eyes gleaming with a strange light. As someone with innate awakening abilities, he could sense energy flows that ordinary people couldn't perceive.

At this moment, he clearly saw that these crystals contained a vast and vibrant energy. This energy seemed to have life, constantly flowing and swirling within the crystals, forming a series of brilliant energy tracks. These tracks were complex and orderly, as if following some profound law.

What shocked Xiao Yi even more was that he found that the energy in these crystals was surprisingly similar to a certain power in his own space. His spatial ability had always been the power he relied on most, and now, he seemed to have found a resonance with his own power in these crystals.

"These crystals... their power is so similar to my spatial ability!" Xiao Yi was shocked and couldn't help but whisper to himself.

Dr. Li noticed Xiao Yi's abnormality and came over to ask, "Xiao Yi, what did you find?"

Xiao Yi came back to his senses, took a deep breath, and told Dr. Li about his discovery. Dr. Li was also surprised after hearing it. He realized that this discovery might mean that they had discovered a new energy source that was completely different from the existing energy system on Earth.

Xiao Yi closed his eyes and deeply felt the power. It was powerful and pure, as if it had some mysterious connection with his own spatial ability. He tried to mobilize his own ability to resonate with the power in the crystal.

At this moment, a startling thought flashed through his mind. Perhaps the mutated animals and plants that had appeared on the surface earlier had undergone such drastic mutations precisely because they had been influenced by the power contained in these crystals underground.

Once this idea came into being, it burned like wildfire in Xiao Yi's heart. He eagerly told Dr. Li and other team members about his discovery.

Upon hearing this, Dr. Li's eyes flashed with shock and excitement. He realized that this discovery might reveal the secrets of the relationship between the underground world and the surface ecosystem, and even provide new ideas for humanity to resolve the crisis posed by mutant creatures.

These crystals... they are so similar to the crystal cores in the zombies' heads!

This discovery made Xiao Yi almost unable to believe his eyes. He clearly remembered that every zombie's head had a crystal core that shone with a cold light. Those crystal cores contained powerful energy and were the source of the zombies' power.

And now, the scene he saw in this crystal world was an almost perfect reflection of the zombie crystal core on the ground. The energy flowing in the crystal and the flickering light were strikingly similar to the energy in the crystal core.

"Could it be that..." Xiao Yi felt a surge of excitement in his heart, "These crystals are the source of the crystal cores? Are they the ones that give the zombies their power?"
