"Rumble! Rumble!"
As that bone-chilling voice rang out, blood-red lightning bolts came crashing down, slamming into Heartless Douluo and Sentimental Douluo's seals. In the blink of an eye, the two Douluos' phantoms vanished completely from the sky!
The instant they disappeared, a blood-red claw large enough to blot out the sky shot out. Like a mountain, it plunged viciously into the silvery-white barrier. In an instant, the entire barrier shattered, utterly unable to resist!
In the blink of an eye, the Blood River God-Slaying Array, which had been compressed within the barrier, surged outward like a flood, sweeping wildly across the surroundings. It seemed as though the vengeful souls of countless Abyssal Creatures clung to it, wailing in piercing agony.
"Open fire!"
At the sight, a commanding voice rang out in the ears of the Federation soldiers.
"Whoosh! Whoosh! Whoosh!"
"Boom! Boom! Boom!"
"Clang! Clang!"
In an instant, countless Fixed-Load Soul Guidance Cannonballs shot skyward like fireworks. The Soul Guidance Detectors above fired crimson Soul Guidance Rays, while the new Soul Tools floating in midair blazed with dazzling light. The next moment, countless scorching, violent storms of Soul Power erupted.
The Abyssal Frontline was instantly shrouded in smoke, and deafening explosions rang out without pause. The Federation's defensive line had been rebuilt and now held a vast stockpile of powerful Soul Tools. It was no longer as fragile as it had been during the Abyss Plane's previous invasion.
Soon, under the ceaseless bombardment of countless Soul Tools, even the divine-level Blood River God-Slaying Array was forcibly halted from spreading any farther.
"Humans, I never expected you to still be holding this line. You've truly surprised me."
Seeing that the Blood River God-Slaying Array had stopped expanding, the Demon Empress hovered above it, gazing down at the entire Federation defensive line.
