All Races Unite to Build a Defense Line, Exploring the Soul Cave's Depths for Corrosion Resistance

After Myriad Arts Academy's emergency meeting ended, cultivators of every race swiftly threw themselves into preparations for the "Extraterritorial Defensive War." The Spirit Clan elders led their foremost scholars in establishing a "Barrier Research Chamber" beside the Origin Rift. By combining origin crystals with the origin runes of the world barrier, they sought a way to reinforce it. Meanwhile, Stone Clan craftsmen led their people to the Nine Great Origins' nodes, using special ores containing Earth Vein Power to forge "Corrosion-Resistant Defensive Arrays" capable of withstanding the Corrosion Origin. Fragments of the Soul Suppressing Seal were embedded at the formation cores to enhance their warning abilities against extraterritorial fluctuations.

Chen Fan and Lin Xiaohu led ten elite disciples from Fusion Academy to Myriad Souls Cave once more—they needed to investigate the Corrosion Origin's properties in depth and find a way to counter it. Before they left, Su Muxue handed Chen Fan an "Origin Detector" infused with the power of the Evil Suppressing Jade Pendant. "This detector can capture the fluctuation frequency of the Corrosion Origin. Once it finds its weakness, it will sound an alert. You must be careful. The Corrosion Envoy may well have laid traps within the Soul Cave."

Chen Fan nodded, tucked the detector into his robes, and led everyone toward Myriad Souls Cave. When they reached the cave entrance again, fine violet cracks had appeared in the area previously sealed by the Soul Suppressing Seal. Fluctuations of the Corrosion Origin continuously seeped from those cracks, while the surrounding rocks had been corroded into dark-purple powder.

"The Corrosion Origin is spreading faster than we imagined." Lin Xiaohu frowned, channeling Soul Suppressing Power into the sealed area and temporarily reinforcing the cracks. "We have to find its weakness as soon as possible. Otherwise, it won't be long before the Soul Cave entrance is completely breached."

The group cautiously entered Myriad Souls Cave. The sight inside was even worse than before: nearly half of the originally pale-violet undead soul origins had been stained deep purple. Countless violet corrosion vines coiled around the undead souls, transforming them into mindless "Corrosion Puppets." These puppets looked much like ordinary undead souls, yet they radiated dense Corrosion Origin aura. Purple corrosion claws condensed in their hands as they howled and charged at the group.

"Careful! These puppets' claws contain the Corrosion Origin. If you're scratched, your origin will be contaminated rapidly!" Chen Fan shouted. The Chaos Power of the Nine Meridians condensed into a "Chaos Corrosion-Resistant Axe"—this time, he had fused a small amount of Soul Suppressing Power into its blade, intending to use the Soul Suppressing Origin against the Corrosion Origin.

The axe blade cleaved toward the foremost Corrosion Puppet. Its violet corrosion claws collided with the blade, producing a sharp sizzling sound. To everyone's surprise, the Soul Suppressing Power on the axe blade actually suppressed the Corrosion Origin temporarily. The puppet's claws froze instantly, then shattered beneath the impact of Chaos Power.

"It works! Soul Suppressing Power can restrain the Corrosion Origin!" Excitement flashed in Lin Xiaohu's eyes. He immediately injected Soul Suppressing Power into the ten elite disciples. "Combine the Soul Suppressing Power with your own fusion power and form corrosion-resistant shields. Don't let those puppets' claws scratch you!"

The elite disciples immediately did as ordered. Some fused Soul Suppressing Power with their blood vitality, forming pale-violet "Blood Vitality Corrosion-Resistant Shields." Others combined it with spiritual energy, condensing violet "Spiritual Energy Corrosion-Resistant Swords." Working together in clear division of roles, their blood vitality and spiritual energy attacks coordinated with the suppressive power of Soul Suppressing Power, swiftly clearing out the Corrosion Puppets along the way.

After they ventured deep into the heart of Myriad Souls Cave, the Origin Detector suddenly emitted a shrill, urgent warning. Its needle spun wildly toward the Soul Suppressing Pool at the deepest part of the cave. "The detector has reacted! The core fluctuations of the Corrosion Origin are near the Soul Suppressing Pool!" Overjoyed, Chen Fan quickened his pace toward the pool.

Beside the Soul Suppressing Pool stood a familiar figure, surrounded by dense Corrosion Origin—it was the Corrosion Envoy from last time! At that moment, he was pouring the Corrosion Origin into the Soul Suppressing Pool, attempting to completely contaminate the Soul Suppressing Origin and open a passage to the outside world.

"I didn't expect you to dare come back!" The Corrosion Envoy turned around, his eyes brimming with icy killing intent. "Today, you will become nourishment for the Corrosion Origin!" With a wave of his hand, countless violet corrosion vines burst from the ground and lashed toward them. The Corrosion Origin on those vines was several times stronger than that of the earlier puppets.

Chen Fan did not dare lower his guard. He thoroughly fused the Chaos Power of the Nine Meridians with Soul Suppressing Power, forming a "Chaos Soul Suppressing Axe," and cleaved at the corrosion vines. Wherever the axe blade passed, the vines were instantly purified, only to regrow moments later—the regenerative power of the Corrosion Origin far surpassed everyone's expectations.

"This won't work! We have to find the Corrosion Origin's weakness!" Lin Xiaohu shouted, hurling the Soul Suppressing Seal into the air. It erupted with pale-violet light, temporarily suppressing the growth of the corrosion vines. "Chen Fan, use the detector to find its weakness. I'll hold off the envoy!"

Chen Fan nodded and immediately activated the Origin Detector. The detector's light resonated with the origin within the Soul Suppressing Pool, and it soon discovered a faint golden fluctuation within the Corrosion Origin surrounding the Corrosion Envoy—it was the Soul Suppressing Origin that had been devoured by the Corrosion Origin!
