Hunting eighth-level and ninth-level magical beasts was extraordinarily difficult, and the preciousness of their Magic Crystal Cores went without saying. Yet the Magic Crystals found at the core of this Magic Crystal ore vein had actually reached the level of seventh and eighth-tier Magic Crystal Cores, with a rare few even comparable to ninth-tier Magic Crystal Cores.
Under the glow of the torches, the semi-transparent Magic Crystals reflected a mesmerizing light.
At the end of the excavated passage stood a door.
A door that should not have existed in this plane.
"My Soul Power can't detect it at all—as if it doesn't exist. What on earth is behind this door?" Lin Lei felt a chill of unease. His Mental Power couldn't penetrate the door in the slightest. In such a mysterious place, would it be wise to intrude?
Lin Lei turned to look at Buck. "Buck, have you been inside?"
Buck nodded. "I have. It's precisely because I've been inside that I'm so shaken."
"But my lord, you should transform before entering. When you step through that door, there's an extremely powerful wave of energy that attacks. If your defense isn't enough… the door's barrier alone will kill any trespasser." Buck said gravely.
Lin Lei was secretly alarmed.
Buck was now a Saint-level Undying Warrior—the most defensively powerful of the four ultimate warriors. If even he said something like that… then the strength of that attack was easy to imagine.
Lin Lei removed his outer garment, revealing a powerfully built physique, and transformed directly into a Dragon Blood Warrior. Deep cyan dragon scales imbued with a lustrous sheen instantly covered his entire body. Lin Lei swept his dark-golden eyes across the mysterious 'door' and stepped right through.
"Ssssss—"
Blade-like waves of energy furiously slashed at Lin Lei ten thousand times over in the instant he crossed the threshold, the continuous assault so rapid it was almost simultaneous. Sparks even erupted from the surface of his deep cyan dragon scales.
"This place…"
The moment Lin Lei stepped inside the door, he was stunned. The scene on the other side was entirely beyond his expectations. Behind the door lay a miniature space resembling a 'transparent bubble.' This miniature space was a spherical chamber, roughly ten meters in diameter.
A spherical space, approximately ten meters across.
Inside the spherical space, it was arranged like a cultivation chamber. There was only a simple bed, a table, and a chair. This spherical space was protected by a membrane that shielded it from outside interference and destruction.
Looking up and around, beyond that transparent membrane churned the chaotic spatial currents.
Spatial currents of every conceivable color swirled wildly, and spatial rifts appeared and vanished from time to time. The terrifying power within them was enough to make Lin Lei shudder just from looking.
"Lord Lin Lei." Buck stepped in behind him. "I was in disbelief when I came here too. Tell me—how do you explain this?"
Lin Lei took a deep breath. "As far as I know, the countless planes all exist within the spatial currents. Take the Yulan Continent plane, for example—in any direction, if you reach the boundary, you'll find spatial currents. Once one's strength reaches a certain level, one can perhaps carve out a small space within the spatial currents."
Lin Lei examined the spherical chamber carefully.
"This spherical, independent space must have been the cultivation chamber of an extremely powerful expert. Moreover, this expert was likely someone from the Yulan Continent plane. Or at the very least… they once were."
Lin Lei couldn't help but feel immense admiration for the powerhouse who had created this small space.
"Carve out a small space?" Buck marveled.
"Didn't the four Supreme Gods each create a Supreme Divine Plane? And didn't the seven Highgod Chief Gods create seven Divine Planes?" Lin Lei smiled. "Creating a small plane of one's own—there are experts capable of that."
Lin Lei understood that even lower gods had only just comprehended the 'Domain of God.' To form a fixed, small plane within the spatial currents was far beyond what an ordinary person could accomplish.
Buck's eyes lit up. "Lord Lin Lei, now I understand why that massive Magic Crystal ore vein appeared. Look—the elemental density inside this chamber is terrifying. Even someone like me with mediocre Element Affinity can clearly feel every type of element. And besides the various elements, there are other forms of special energy as well."
Lin Lei could also sense the dense World Elements surrounding them.
Earth, Fire, Water, Wind, Lightning, Light, and Darkness—all seven systems were present at an unprecedented density. Beyond these seven, Lin Lei also detected other surging energies—some similar to Sesser's power, others radiating a terrifying aggressiveness, and still others brimming with vitality…
"That should be the energy of the four Supreme Gods." Lin Lei knew that besides the seven elements, there were four other, far more mysterious types of special energy.
Lin Lei looked at Buck. "That door should be the junction between this space and the Yulan Continent plane. I suspect it's precisely the existence of this chamber that attracted vast quantities of elements to gather around it, which is what caused this enormous, ellipsoidal Magic Crystal ore vein to form with that door at its center."
"However…"
"That mysterious expert's cultivation must have been from a very, very long time ago." Lin Lei was certain of this.
"Oh?" Buck looked at him quizzically.
"Without that mysterious expert actively cultivating here, there would have been no mechanism to draw in such massive quantities of World Elements. We've been in the Domain of Chaos for quite some time now—if we hadn't excavated this Magic Crystal ore vein, who would ever have discovered the huge amount of Magic Crystals hidden here?"
Lin Lei smiled. "By the laws of formation, before such a massive Magic Crystal ore vein could come into being, there must have been an enormous concentration of World Elements gathering here first. For a vein of this magnitude to form, the degree of elemental convergence would have been absolutely terrifying. Surely every expert on the entire Yulan Continent would have noticed it."
"Yet no one in recorded history has ever mentioned such a thing. That means this mass elemental gathering must have occurred an extremely long, long time ago."
As he spoke, Lin Lei suddenly closed his eyes and sat down cross-legged.
"Lord Lin Lei?" Buck called out softly.
