The Trans-Dimensional Mist churned violently as the Wall of Unknown appeared. Countless frenzied Energy Threads scattered like startled fish, only to gather around the wall and form vortex-like Energy Flow. The wall was not a physical structure, but an Energy Barrier woven from countless unknown runes. The runes flickered with shifting light, and each flicker carried the cold rhythm of "No Passage," as if it were the first gate of the Trans-Dimensional Unknown Domain, cutting off outsiders from prying into the secrets of the Origin.
Xuan Fu's Trans-Dimensional Primordial Light hovered before the Wall of Unknown, while his Spiritual Sense spread out at full strength in an attempt to decipher the mysteries of the runes. These runes possessed neither the rigid quality of rules nor the flexibility of the void. Nor did they resemble the traits of Forms of Power such as plurality or unity. Their arrangement and combination followed an entirely new logic that Xuan Fu had never encountered, as if it were an "Origin Law" independent of every known power system.
He tried injecting his Trans-Dimensional Primordial Light into the runes, hoping to find a way through. However, the moment the light touched the wall, the runes instantly repelled it. The force of the rebound contained pure repulsion. It neither harmed nor corroded him, yet it precisely kept foreign energy outside the wall. Xuan Fu could even sense a hint of "discrimination" within that repulsive force, as if it were judging whether he possessed the qualifications to pass.
"This Origin Wall isn't merely a Defensive Barrier. It's more like a trial of qualification." Xuan Fu muttered to himself. Countless thoughts flashed through his Trans-Dimensional Primordial Light. "To pass through, I must understand the logic of the Origin Runes—or gain the Guardians' approval."
He did not recklessly attack again.
