Looking at Kai's calm face, the Slaughter King said in a deep voice again, "Pluto, I'll give you a chance. Retreat now, and you will still be my Slaughter King's honored guest."
"And I will fulfill all your wishes, even if it means giving you my Hell Emissary, there's no problem, but she cannot leave Slaughter City."
Kai smiled, "Wouldn't that mean I'd be stuck here too?"
"It seems you insist on fighting?" The Slaughter King's eyes flickered with blood-red light, and he thought to himself, "Pluto has a deep relationship with that Slaughter God from Spirit Hall... I naturally cannot kill him..."
"He's only a Spirit Emperor. I'll just teach him a lesson."
Boom!
Blood-red Killing Intent surged, filling the sky.
In an instant, the entire Slaughter City seemed to boil. Some of the degenerates around were terrified and fled in disarray.
Kai was surrounded by surging Chaotic Aura, appearing in a state of nothingness, neutralizing the Slaughter King's Killing Intent.
"Hehe, Pluto, don't think that just because you possess the Slaughter God Domain, you can use Martial Soul Abilities in a fight with me."
"My Slaughter Domain can restrict your Slaughter God Domain. You still won't be able to use Martial Soul Abilities. Give up, Pluto."
The Slaughter King still hadn't made a move.
Relying on his unique Slaughter Domain, even if Kai possessed the Slaughter God Domain, in his opinion, it was useless.
Kai didn't answer him. Instead, the terrifying Killing Intent within his body transformed into Chaos Light, surging around him. The Chaos Light seemed to have formed a unique Domain, containing vast Killing Intent!
"Chaos Domain!"
"Boom!"
The Chaos Domain blossomed, instantly elevating Kai's aura to its Peak state, and it seemed to suppress the Slaughter Domain!
"Barren Domain!"
With the two Domains superimposed, the Chaos Splitting Axe in Kai's hand unleashed its most powerful force. As the Fourth spirit ring beneath Kai's feet appeared, the Chaos Splitting Axe directly transformed into a Formation and flew out like a flash of light.
"Fourth Spirit Skill, Chaotic Cleave!"
"What!?"
The Slaughter King's pupils contracted slightly, then he directly extended a hand, and surging Killing Intent erupted, forming a blood-red tide that slammed forward.
With a loud boom, the attacks of the two instantly shattered. However, the seemingly formidable Slaughter King retreated two steps at this moment, his arm even trembling violently.
"How is this possible... How can you still use Martial Soul Abilities?"
The Slaughter King's gloomy voice rang out.
"The Slaughter God Domain just evolved a bit. Let's fight with all we've got, Slaughter King."
Kai held the Chaos Splitting Axe, and then the Vermilion Bird Wings appeared behind him, landing in front of the Slaughter King.
After the Slaughter God Domain evolved into the Chaos Domain, it not only allowed Kai to freely use Martial Soul Abilities in front of the Slaughter King, but it also transformed the originally cold and violent Killing Intent into an extremely vast Killing Intent, containing the power of Chaos.
"Good, good!"
The Slaughter King roared and truly made his move.
His figure transformed into a blood-red light, charging towards Kai, clearly enraged.
Kai's Chaotic Aura completely enveloped his body, and then the Vermilion Bird Fire began to rise. Facing the Slaughter King, Kai fearlessly charged forward.
"Boom!"
A terrifying explosion erupted in the sky above Slaughter City.
Even the aftershocks of the explosion leveled the surrounding buildings. The Girl in Black, who had been there earlier, had not left but stood not far away, anxiously watching the battle in the sky.
"He's actually fighting the Slaughter King for me..."
The Girl in Black felt it was unbelievable.
The Slaughter King was a Titled Douluo, and Kai seemed to be just a Spirit Emperor.
How could they fight?
Low rumbling sounds of collision continuously echoed in the air, accompanied by boundless firelight blossoming.
Kai's figure stepped out from within, the Chaos Splitting Axe in his hand reflecting a brilliant light, while simultaneously erupting with Chaotic Aura and the power of Desolation.
"Boom!"
The Slaughter King retreated, looking at the Chaos Splitting Axe in Kai's hand with some doubt.
"What kind of Martial Soul is this? I never noticed it before. This Martial Soul actually possesses such terrifying power..."
Kai pouted, "That guy's terrifying Killing Intent around him is indeed troublesome, but that's all it is."
However, Kai still felt immense pressure facing a powerhouse like the Slaughter King.
This guy's strength had definitely reached the Peak level of ninety-ninth rank, and with his terrifying Killing Intent, even Qian Daoliu was not his opponent.
Even Bo Saixi, without the power of the sea, would probably not be his opponent.
"Pluto, you've angered me."
The Slaughter King unfurled a pair of enormous bat wings behind him, the blood-red light so dense it resembled flowing water, extremely viscous.
"Rumble!"
The Slaughter King's attack was too terrifying, as if it contained world-shaking power. In an instant, it crossed several hundred meters and landed above Kai.
"Chaos Body Protection, Hand of Desolation!"
Simultaneously releasing his Second Spirit Skill and Fifth Spirit Skill, as the Chaotic Aura surged, the power of Desolation suddenly erupted, transforming into an energy handprint that slammed out forcefully.
The energy handprint pierced through the air, striking the flash of light in the sky.
Then Kai attacked again. The Chaos Splitting Axe transformed into a beam of light and struck horizontally. At the same time, the five hundred thousand year spirit rings on Kai's body shone, reflecting a sky full of red light.
"Boom!"
The second martial soul appeared, its light seemingly engulfing Kai. Thunder and lightning flashed across the surrounding area, and a True Dragon coiled in the sky.
"Thunder Emperor Treasure Art's profound mystery, Nine Heavens Tribulation Light!"
"True Dragon Treasure Art!"
At this moment, Kai unleashed the Thunder Emperor Treasure Art's strongest profound mystery, the Nine Heavens Tribulation Light. The thunder and lightning of heaven and earth seemed to pierce through space, transforming into an incomparably terrifying beam of light descending from high in the sky!
The Nine Heavens Tribulation Light erupted with endless runes, which swirled around, exuding scorching thunder power.
At the same time, the shadow of the True Dragon coiled around, once again erupting with brilliant runes, and together with the Nine Heavens Tribulation Light, it slammed down towards the Slaughter King.
In his truly explosive state, the terrifying offensive power Kai displayed at this moment made the Slaughter King's face change, even making him feel incomparably terrified. He subconsciously summoned blood-red aura to protect his body.
"Not good, I can't block it!"
The Slaughter King retreated repeatedly, but he couldn't escape the terrifying attack unleashed by Kai.
The two attacks seemed to pierce through space. The Nine Heavens Tribulation Light descended like divine punishment, containing the true power of the Heavenly Dao Law, and the True Dragon Treasure Art, moreover, manifested endless visions in the sky, unleashing boundless power that enveloped the Slaughter King.
