Following Yao Ao's order, all the standby beast slaves let out roars one after another.
These magical beasts contained the cultivators from the three major Dou Ancestor sects who had died in that ancient war. They never imagined that even 300 years after their deaths, they would still be forced to participate in battle.
A torrent of steel-like beast slaves charged forward, kicking up immense clouds of dust and sand.
Only when the horde of beast slaves got closer did Xiao Yan clearly see that these beast slaves were actually the magical beasts of the Magic Beast Mountain Range.
The stampeding magical beasts came in all shapes and sizes. Some were like gigantic pythons, extremely thick and over a dozen meters long. Flames coated their entire bodies, leaving a trail of charred black marks on the ground as they slithered. Others resembled crabs with eight legs; though not very large, they moved with lightning-like speed as they darted to the very front.
It could be said that over these 300 years, countless strange magical beasts had fallen victim to Yao Ao's vile methods and been turned into beast slaves.
Xiao Yan's eyes sharpened and he unleashed the Mad Lion Chant. However, unlike before, the illusory figure appearing behind him was not the Blood Fury Mad Lion but the Eight-Winged Flame Demon Tiger.
Blood Fury!
Xiao Yan stomped heavily on the ground. The illusory figure of the Eight-Winged Flame Demon Tiger behind him mirrored the action with its massive paw. Instantly, eight cracks spread out from where his foot landed as scarlet magma surged forth in all directions.
Boom! Boom! Boom!!! The magma's destructive force was unleashed. The Mad Lion Chant was originally a Dou Technique that combined Dou Qi and physical strength. Now, with the support of the Eight-Winged Flame Demon Tiger's power and the strength of the Ten Thousand Beast Flame, even Xiao Yan's mere wave of his hand possessed immense destructive power.
Back then, when Yun Yun had summoned four tornadoes with a wave of her hand, it was only about this level of power. Xiao Yan had now touched upon a bit of the strength of a Dou Emperor.
The terrifying magma instantly melted the charging beast slaves the moment it slammed into them. Even bodies that had been enhanced by the Ten Thousand Beast Flame were unable to withstand this blood-red magma.
Xiao Yan didn't stop his offensive momentum as he gazed at Yao Ao who was hiding behind the beast slaves not far away. The Dou Qi within his body circulated as if it had gone berserk while the Ten Thousand Beast Flame continuously condensed!
"Mad Demon Blaze!"
The eight fiery wings behind him suddenly spread open. Xiao Yan let out a shout and the wings flapped forcefully. The illusory figure of the Eight-Winged Flame Demon Tiger behind him opened its mouth wide and spat out an incomparably scorching blaze, just like how the Demon Tiger had unleashed its Beast Skill Demon Blaze in the past.
Borrowing the power of Xiao Yan's Dou Techniques, Dou Qi, and the Ten Thousand Beast Flame, the Beast Skill of the Eight-Winged Flame Demon Tiger was recreated in another form!
Roar!! The entire cave trembled when the Demon Blaze was unleashed. The former Lord of the Magic Beast Mountain Range could destroy the sky above and the earth below. Even though the power of this Demon Blaze was less than one percent of the original, it was still extremely terrifying.
One of the special abilities of the Ten Thousand Beast Flame was that it could transform Dou Qi and Dou Techniques to recreate the Beast Skills of ten thousand beasts!
Even Mu Long, who had already retreated to the cave entrance and was ready to flee at any moment, couldn't help but be horrified when he saw such a demonic flame attack. The Eight-Winged Flame Demon Tiger had once been a peak Rank 7 magical beast, and the power of its ultimate Beast Skill made even him tremble a bit.
Every kind of Heavenly Flame in this world should never be underestimated. While its inherent power might not be high, its unique abilities were always extraordinarily mystical.
Yao Ao's expression changed drastically when he saw this world-destroying Demon Blaze rushing over. He also controlled the Ten Thousand Beast Flame and used his powerful Spiritual Strength to form a fire shield to protect himself.
"Spiritual Medicine Fire Shield!"
He couldn't bring out the special abilities of the Ten Thousand Beast Flame and could only use the portion he had snatched away as an ordinary fire source!
Even though many beast slaves had used their bodies to reduce the power, Yao Ao's fire shield could not withstand the attack and was sent flying with a loud crash. After that, he staggered back several steps and spat out a mouthful of blood.
The offensive didn't slow for a moment.
With an explosive boom, Xiao Yan activated his Exploding Steps. Coupled with the acceleration from the flapping of the eight wings, his speed was simply too fast to be seen.
Breaking through the waves of fire, Xiao Yan instantly closed in on the retreating Yao Ao. His right hand tightly grasped the Heavy Xuan Ruler as he swept it horizontally across Yao Ao's body.
Crack crack crack! The sound of shattering bones echoed with a crackling sound. The sheer physical strength of Xiao Yan at this moment was nothing short of terrifying.
The onslaught came like a torrential storm. The eight wings spread open as he chased after Yao Ao while frantically hacking with the Heavy Xuan Ruler.
Both Xiao Yan and Yao Ao knew that the outcome of their battle depended on who could endure longer. The power the Eight-Winged Flame Demon Tiger had preserved within the Ten Thousand Beast Flame was very little. It was just an ephemeral flash of brilliance, while Yao Ao was a complete soul body.
If Xiao Yan couldn't turn Yao Li's body into a bloody pulp and force out Yao Ao's soul before the borrowed strength dissipated, he would lose.
The opposite was true for Yao Ao!
Mu Long had already stopped attacking. He knew the victor would soon be decided. If Xiao Yan won, he would immediately flee without saying a word. But if Yao Ao won, he would instantly move to capture the Amethyst Winged Lion King.
"Yao Ao! This is the end!"
Xiao Yan kicked Yao Ao out of the air and slowly descended to the ground. The Heavy Xuan Ruler in his hand had become incomparably scorching hot.
Flame Splitting Tsunami! This was currently Xiao Yan's most proficient and powerful Dou Technique!
With a thunderous boom, scarlet flames gushed out from the Heavy Xuan Ruler the moment Xiao Yan's power erupted. Streaks of flames shot into the sky from the ruler, illuminating the entire underground world.
The erupting light resembled a long river of history, and the moment this river appeared, the spirits of various magical beasts stood within it.
The Flame Splitting Tsunami fused with the Ten Thousand Beast Flame and obtained the boost from the power of ten thousand beasts. Under this kind of power, everything else seemed so insignificant. This was the flame formed from the spirits of ten thousand beasts gathered in the Magic Beast Mountain Range over hundreds and thousands of years. Any existence would be instantly crushed under this power!
"Flame Splitting Tsunami—Ten Thousand Beast Flame Wave!"
Xiao Yan swung the Heavy Xuan Ruler toward Yao Ao not far away, unleashing his strongest blow. The Ten Thousand Beast Flame transformed into a hundred-meter-long fiery radiance. This radiance contained the power of ten thousand beasts, as if ten thousand beasts were stampeding within it.
Yao Ao let out an angry roar as he saw the Ten Thousand Beast Flame Wave charging at him. He knew this was Xiao Yan's final strike. As long as he could withstand it, he would win!
Countless beast slaves charged toward the Ten Thousand Beast Flame Wave like moths to a flame, but no matter how many came, they were all turned to ash in an instant.
"Do not underestimate the Yao Clan! High Di Class Dou Technique—Pill Spirit Garden!"
A series of clear, crisp sounds rang out as Yao Ao poured out several dozen to over a hundred medicinal pills from his storage ring. Healing pills, strength-enhancing pills, detoxification pills—whether they were 1st, 2nd, or 5th tier, he emptied them all out.
Using his incomparably terrifying Spiritual Strength, he controlled all the medicinal pills and arranged them side by side to form a beautiful and serene pill garden!
He could actually use medicinal pills to unleash a Dou Technique. This completely exceeded Xiao Yan's imagination!
The power of ten thousand beasts versus a hundred pills!
The terrifying Ten Thousand Beast Flame relentlessly melted the pills, while the medicinal effects of the pills worked to quell the flames.
Seeing the two energies clashing more and more fiercely until they gradually began to die down, Yao Ao burst out laughing, "Hahaha!! I have the last laugh! How could the remnant soul of a mere Rank 7 magical beast be a match for me, Yao Ao! The Ten Thousand Beast Flame is mine!"
Illuminated by the scarlet firelight, Xiao Yan also revealed a smile as he watched the Ten Thousand Beast Flame Wave that was about to be completely extinguished.
"You have no other means of defense left, do you?"
Yao Ao's heart skipped a beat when he heard these words. A feeling of extreme unease suddenly welled up in his heart.
The underground world that was originally illuminated bright red by the Ten Thousand Beast Flame suddenly saw the appearance of a second color.
Bone-white!
A bone-white flame slowly rose into the air, and at the sight of it, the pupils of Yao Ao, Mu Long, and the Amethyst Winged Lion King all contracted violently.
"Holy crap! You have a second Heavenly Flame?!!"
With a crisp sound, Xiao Yan lightly flicked his finger as if he were flicking off cigarette ash. A wisp of black flame rapidly crashed into the Bone Chilling Flame like a tiny spark. The black flame was so faint that it was almost imperceptible.
When Xiao Yan first refined the Nihility Devouring Flame, he noticed that Mao Wu did not dare to enter the storage ring to touch the Bone Chilling Flame.
The Nihility Devouring Flame could devour anything, even the flames of other Heavenly Flames could be devoured into energy, all except for the Essence Flame of a Heavenly Flame.
Because once the Essence Flame of a Heavenly Flame encountered the Essence Flame of another Heavenly Flame, the result would be—
"You probably don't know, but true art is... an explosion."
With a snap, the black spark made contact with the Bone Chilling Flame.
A beam of dazzling bone-white light replaced everything else as it cast its glow onto Yao Ao's horrified face.
BOOM!!!
