Boom! Boom! Boom!
The phantom projections of the great horn blazed across the sky in all directions, unleashing a tempest of attacks.
Surrounding Snow Blade Ancestor, freezing cold energy radiated outward in waves. Surging blue frost crashed toward Jiao Lianying's forces in layer after layer.
Two of the Central Continent's Eighth Transformation Gu Immortals within the Jiao Lianying gritted their teeth and held their ground, while the other Gu Immortals behind them scrambled to repair the Immortal Gu House, all drenched in sweat and panic written across their faces.
At Snow Blade Ancestor's side, Lord Purple Mountain radiated a blinding violet glow that illuminated the entire Great Snow Mountain Blessed Land.
The Central Continent side attacked the Great Snow Mountain, while Lord Purple Mountain was responsible for defending this blessed land. This blessed land was the very foundation of the Reversed Fate Sacrifice Refinement Grand Formation—as long as it held, the Central Continent was doomed to fail.
"What are we going to do?" At this moment, a trace of panic surfaced on Bi Chentian's face. "If this goes on, not only will we fail to save Zhao Lianyun and Ma Hongyun, we might even lose this Immortal Gu House and ourselves along with it!"
As the leader of this operation, Wei Lingyang's expression was utterly grave.
The situation before them was extremely unfavorable for the Central Continent side.
One could even say there was not a shred of hope left.
According to the Central Continent Gu Immortals' battle plan, they were originally supposed to split into two forces. One force would temporarily tie down the Heavenly Palace of Fortune Suppression, while the other would rescue Ma Hongyun and Zhao Lianyun, then immediately rendezvous with the first force and withdraw from the Northern Plains.
But now, the force at the Great Snow Mountain Blessed Land could barely keep itself alive, while the other force was still counting on them for rescue.
After all, this was the Northern Plains, not the Central Continent.
Three Eighth Transformation Gu Immortals, three Immortal Gu Houses, and numerous other Gu Immortals—and they still felt pitifully outmatched.
Of course, this was partly because the Northern Plains Gu Immortals had come prepared. Giant Sun Immortal Venerable's plan from back in the day was something the Central Continent side had known nothing about.
The Central Continent had launched a powerful strike, and according to the ambush plan, there had been a very real possibility of success.
However, as events unfolded, the ambush devolved into a frontal assault, and Ghostly Soul Demon Venerable's arrangements only made things worse—plunging the Central Continent Gu Immortals into such a passive and perilous position, hanging by a thread.
Wei Lingyang's mind raced with calculations.
After a long moment, he clenched his teeth savagely, as though summoning every ounce of strength in his body, and gave the order: "We're retreating!"
Forget about Zhao Lianyun and Ma Hongyun.
With the appearance of Lord Purple Mountain, the situation had already exceeded Wei Lingyang and his group's capabilities.
Any further delay, and the Central Continent side would suffer even greater losses!
Wei Lingyang decided to withdraw immediately—fall back into the Black Heaven, rendezvous with the other two Immortal Gu Houses, and flee back to the Central Continent together.
With the Jiao Lianying determined to leave, even Snow Blade Ancestor and Lord Purple Mountain combined would not be able to stop it. After all, they had no Immortal Gu House and could not withstand the Jiao Lianying's headlong charge.
But!
Just as the Jiao Lianying was about to burst out of the Gu Formation, an abrupt change erupted.
The entire Great Snow Mountain Blessed Land convulsed with violent tremors.
The sky shattered and the earth split!
"What's happening?!"
"The blessed land seems to be collapsing!"
Zhao Lianyun and the others, along with the remaining surviving Peak Lords, were all struck with utter shock.
Rumble, rumble, rumble.
Amid the thunderous, muffled roars, snow peak after snow peak began to crumble.
"What's going on!?" Astonishment also appeared on Snow Blade Ancestor's face.
"The entire Grand Formation is collapsing on its own," Lord Purple Mountain said, his eyes shooting out purple light. Then he abruptly corrected himself. "No! This formation..."
Before he could finish, the Gu Immortals present heard wave after wave of surging water.
The next instant, a raging torrent materialized seemingly out of thin air, sweeping across in all directions!
It was the Heavenly Secret Realm—the Reverse Flow River!!
"Damn it, my wife!" Everything happened far too fast. Snow Blade Ancestor tried to rush back toward the First Snow Peak, but halfway there, he was engulfed by the Reverse Flow River's torrential current.
