The Eighty-Eight True Yang Building.
Dense, countless Wind Blade Birds descended upon the allied forces like a dark cloud covering the sky.
These Wind Blade Birds had beaks as sharp as swords and their wings were curved and sharp like scythes. They flew with extreme speed, leaving afterimages in the air as they charged fearlessly.
"Kill, kill, kill!" Hei Lou Lan roared. Black smoke roiled violently around him, splitting into countless black tentacles that seized and devoured the surrounding Wind Blade Bird.
The fierce battle had been going on for an hour. The army and the Wind Blade Birds were locked in a deadly struggle, both sides suffering heavy casualties.
The ground was carpeted with the bodies of birds, as well as a large number of dead Gu Masters.
"Aaaah..." Hei Lou Lan bellowed, his eyes bloodshot. He suddenly stretched out his right hand.
His hand formed a claw, and countless dark streams of light materialized out of thin air. They swirled briefly in the sky before gathering into the center of his right claw.
In the blink of an eye, hundreds, thousands of dark streams converged into a black sphere of light in Hei Lou Lan's claw, like a hundred rivers flowing into the sea.
The sphere was an unfathomable deep black, rotating rapidly, emitting a sound like a roaring wind and thunder.
"Go!" Hei Lou Lan's eyes suddenly flew open wide. With a great shout, he gathered all his strength and fiercely raised his right claw towards the sky.
Holding the black sphere, he looked as if he was lifting a weight of a thousand jun. His entire movement was slow and strenuous.
With this motion, the sphere slowly rose into the sky.
In midair, it rapidly expanded. In just a few short breaths, it actually swelled to the size of a small mountain!
For a moment, the black sphere occupied a small part of the sky above the allied forces.
Countless Wind Blade Birds were caught within it, instantly eroded and corroded into nothing, not even their bones left.
The entire process was silent, bizarre and utterly domineering, sending a chill down the spines of those who witnessed it.
This was Hei Lou Lan's signature killer move — Dark Tide!
The Dark Tide lasted for the span of six breaths, killing tens of thousands of Wind Blade Birds.
The Wind Blade Bird flock was too large, and they were all gathered in the air above the allied army, so the casualties were shocking.
After the Dark Tide disappeared, a clear hole appeared in the sky. But soon, the surrounding Wind Blade Birds filled it in like flowing water. The sky above the Gu Master allied forces was once again occupied by the Wind Blade Bird flock.
This was already the twenty-fifth level of the sixty-eighth floor of the Eighty-Eight True Yang Building.
The number of Wind Blade Birds was truly too great. It included a large number of Bird Kings, making the obstructing force too powerful.
In fact, based on their previous experience, it wasn't hard to guess that clearing this level must have a special trick. However, Hei Lou Lan chose to directly rush in with brute force, mobilizing all the power he could to bulldoze through.
This drew the frenzied counterattack of the Wind Blade Birds.
"Haha, kill all these dead birds!" Over there, Ye Li Sang burst out laughing. Hei Lou Lan's outburst had stirred his fighting spirit.
The Ye Li family was equally famous as the Hei family, both being super forces with a Gu Immortal in command. Ye Li Sang and Hei Lou Lan held equal status, both being the current clan leaders of their super forces.
Seeing Hei Lou Lan use his killer move to annihilate a massive number of Wind Blade Birds, he naturally did not want to be outdone.
"Watch my newly developed killer move — Fire Fiend!"
Ye Li Sang let out a loud cry, his sleeves fluttering. His true essence exploded, frantically stimulating the Gu worms in his hands.
With a *whoosh*, flames erupted from his whole body, flaring up to the sky and forcing the surrounding Gu Masters away.
Within a radius of several hundred paces, only he remained.
He shook his body, and the towering flames burning fiercely around him separated a part, forming a three-zhang tall vajra completely made of flames.
The face of the Flame Vajra was ugly, with fangs and strange horns, its muscles bulging. This was the Fire Fiend!
The Fire Fiend shot into the sky, charging wildly in the air. Every Wind Blade Bird it encountered was ignited instantly, screeching loudly as they burned.
As it passed, flames raged in a line. A large number of Wind Blade Birds were roasted in the blink of an eye, falling to the ground with heavy *thuds*.
The Fire Fiend rampaged in all directions, immediately attracting the attention of many birds, significantly reducing the pressure on the army of Gu Masters on the ground.
"What a 'Fire Fiend', it's nothing special!" In the distance, Hei Lou Lan laughed loudly, proud and ostentatious.
Ye Li Sang cackled loudly as well: "Clan Leader Hei, take another look!"
As he spoke, he shook his whole body continuously, shaking off flames to form more Fire Fiends.
Hei Lou Lan's expression changed. It wasn't just him, even Fang Yuan in the army narrowed his eyes. The Fire Fiend's power was so astonishing, and yet there was more than one?
The Eighty-Eight True Yang Building brought opportunities. It wasn't just Fang Yuan, Hei Lou Lan, and the others who were improving; all the other Gu Masters were also making great gains.
It was only when six Fire Fiends had joined the battlefield that Ye Li Sang's flames were completely shaken off.
"Six Fire Fiends, that's manageable..." Fang Yuan retracted his gaze.
Hei Lou Lan's expression also relaxed slightly.
