Full defense!
The Legion Commander of the Black Tortoise World Suppressing Camp's First Camp roared.
Boom! Boom! Boom!
The square formation of nearly ten thousand men erupted with their strongest Calamity Power in unison, gathering it together.
The phantom Black Tortoise condensed in the void grew ever more imposing. Dazzling light flashed across its shell, like an impregnable barrier.
Boom!
At that moment, the Star Battle Axe came crashing down upon the Black Tortoise's shell, unleashing violent tremors. Every immortal soldier of the Black Tortoise World Suppressing Camp's First Camp shuddered violently and spat blood.
Yet each of them endured the pain, forcibly maintaining the battle formation as they held on bitterly.
Mu Hanxue and the others fared no better. Using the Sky Slaughter Formation to fight the strong while weak, they too suffered a powerful backlash, each coughing up blood.
Hold on! Kill!
Mu Hanxue shouted, and the battle axe once more gathered astonishing might before erupting with a heaven-destroying, earth-shattering strike toward the Black Tortoise battle formation.
Rumble!
Terrifying thunderous booms rang out as dreadful shockwaves swept in all directions.
The immortal soldiers around the drill ground could not help but turn pale in horror, their faces filled with disbelief.
This collision of battle formations was simply too terrifying. The power it unleashed was not the least bit weaker than a Nine Calamities Transcendence expert unleashing an Immortal Path Technique with all their strength.
Crack!
Vast stretches of void shattered wildly, unleashing surging Void Storms. Cracks also began spreading across the Black Tortoise phantom. Under the Sky Slaughter Formation's axe strike, it broke apart inch by inch before finally collapsing outright.
All the immortal soldiers of the Black Tortoise World Suppressing Camp's First Camp suffered backlash as well. One after another, they were sent flying through the air
