Zuo Feng raised his hand and opened his mouth, intending to stop Tiegada's actions, but after thinking about it, he ultimately did not.
Although the test of the Six-Slash ability had not been completed, Tiegada at this moment had already displayed an uncontrollable desire.
Zuo Feng thought for a moment and then allowed Tiegada to continue its behavior.
The Six-Slash Zombie could be catalyzed again, but Tiegada's evolution was rare and precious. Zuo Feng also wanted to see what level Tiegada would reach after completely devouring a Six-Slash Zombie.
As Tiegada approached, the Six-Slash Zombie's struggles became more violent, and a rare glint of fear flickered in its eyes.
No matter how it struggled, it was all in vain under the restraint of the a-level metal chain.
Tiegada approached step by step, its massive body like a moving mountain, bringing an endless sense of oppression.
"Roar..." Tiegada suddenly opened its large mouth, and four silver fangs gleamed with cold light, biting fiercely towards the Six-Slash Zombie's forehead slash.
Everyone watched this scene dumbfounded, originally thinking that Tiegada would devour the entire Six-Slash Zombie.
However, Tiegada instead pounced the Six-Slash Zombie to the ground, and the moment its four silver fangs deeply pierced the Six-Slash Zombie's brow, the silver light on its body suddenly surged, spreading like a tide from the point of contact to its entire body.
A ripple of distortion appeared in the air, as if energy was being extracted and reorganized in an instant.
As the silver light flowed, the Six-Slash Zombie's body trembled violently, as if every inch of muscle was being torn and reorganized by some invisible force.
Tiegada's silver light and the blood-red patterns on the Six-Slash Zombie's body fiercely intertwined, as if two completely different forces were vying for dominance.
The Six-Slash Zombie let out a sharp roar, its voice mixed with pain and unwillingness, but as the silver light became more dazzling, its struggles gradually weakened.
Everyone's pupils constricted, only to see the Six-Slash Zombie's blood-red patterns rapidly dim under the erosion of the silver light, and then those patterns seemed to be peeled off from beneath its skin, turning into streams that flowed into Tiegada's body through the wound where Tiegada's fangs had pierced.
Visibly, the silver patterns on Tiegada's body became deeper and more intricate, with a blood-red pattern slowly emerging in the center, as if a touch of crimson was dotted in a silver ocean.
Tiegada's body trembled slightly, as if enduring some violent energy impact.
A strange energy fluctuation filled the air, carrying the chill of metal and the stimulating sweetness of blood.
Zuo Feng's eyes narrowed, keenly sensing that after Tiegada devoured the Six-Slash Zombie's slash energy, its aura was undergoing a drastic change, and all the vertical slashes on its brow had turned silver.
A blood-red core was dotted in the center, like a beating heart within silver lightning.
And the fourth vertical slash was slowly condensing at a visible speed, the originally illusory trace gradually becoming clear, until the fourth vertical slash was about to fully form, then it stopped growing.
Zuo Feng's heart jolted; he could clearly perceive that Tiegada had now surpassed any previous evolution, not only absorbing the Six-Slash Zombie's core energy but also transforming it into a part of itself.
This was a qualitative leap, as if breaking through a long-standing constraint.
Tiegada directly skipped a major level, just one step away from entering the ranks of four-slash variant species.
Moreover, the change in the color of the vertical slashes and the crimson infiltration, as well as the blood-red tinged silver patterns on its body, seemed to imply some kind of mutation in Tiegada at the fundamental energy level.
This mutation was not a simple strengthening, but a fusion evolution with some unknown characteristics.
As for the specific changes, they remained to be observed, but everyone could clearly feel it.
Tiegada now clearly exuded a terrifying pressure, as if a violent but not yet fully released power was contained within its body.
Compared to the Six-Slash Zombie at its peak, its aura was dozens of times stronger.
Tiegada slowly raised its head, and its originally cold metal pupils now contained a crimson glow mixed with silver, even its nails and hair were turning silver, with intricate silver patterns appearing on the surface, slowly flowing like living things.
That blood-red pattern was like a meridian, running through Tiegada's entire body of silver patterns, faintly emitting a terrifying and eerie glow.
It wasn't until several tens of minutes later that Tiegada's aura gradually stabilized.
Zuo Feng, Da Bai Tu, and Da Mi Tao exchanged glances again, their eyes filled with undisguised joy and excitement.
If Tiegada could evolve, did that mean other variant species could also evolve in this way?
However, now was not the time for testing.
Lu Zhuoyan leaned towards Zuo Feng, whispering excitedly, "Congratulations, Brother Zuo!"
Anyone who wasn't a fool could see that Tiegada had completed a qualitative leap, and as Tiegada's owner, Zuo Feng was undoubtedly the most benefited person.
Moreover, Huo Yao Base and Firefly were allies; the stronger Firefly became, the more beneficial it was to Huo Yao Base.
Zuo Feng's lips curved slightly, and he nodded gently, but his mind remained calm; the experiment had to continue, but a new Six-Slash Zombie needed to be catalyzed, which would also allow these leaders to witness firsthand the growth rate after the pathogen outbreak.
The Six-Slash Zombie in the arena was now completely dead, its brow slashes and body patterns entirely devoured by Tiegada, leaving only a shriveled husk.
Zuo Feng pondered for a moment, then gestured to Da Bai Tu. Da Bai Tu understood, and led Tiegada to immediately turn and walk towards Firefly Base.
Zuo Feng smiled and said to everyone, "Please wait a moment, you will soon see the birth of another Six-Slash Zombie."
Upon hearing this, everyone showed expectant expressions, nodding in agreement.
Mao Wudi frowned slightly, staring at the shriveled corpse in the arena, deep in thought.
"Left Leader Zuo, may I examine this corpse to see if it has a loss crystal, and how many lines of loss crystal it will produce?"
Zuo Feng was slightly taken aback; he hadn't really paid attention to this aspect, but since Mao Wudi asked, he himself wanted to see, so he nodded in agreement.
After receiving permission, Mao Wudi slowly walked towards the shriveled corpse. He directly stabbed his spear into the corpse's heart. Presumably because the energy had been sucked dry, Mao Wudi's spear precisely and unimpededly pierced into the corpse's heart.
With a crisp "crack," Mao Wudi's spear tip prised out a dull, blood-red crystal.
Mao Wudi picked up the crystal, examining it carefully, his brows gradually furrowing. The crystal was already covered with shattered cracks, almost without any luster, as if it could break at any moment. It was likely that all the internal energy had been sucked dry, and even the loss crystal had not been spared.
A gentle breeze swept across the area, stirring up some dust. The blood-red crystal in Mao Wudi's hand trembled slightly in the wind, then with a "snap," it completely shattered into countless particles, scattering in the wind.
Everyone's eyes narrowed, not because of the broken loss crystal, but because everyone clearly saw that the surface of the blood-red loss crystal had eight clearly visible lines, which meant it was an—eight-line zombie crystal!
