The Black Flame Lord deftly avoided the impact, its wings flaring as it soared above the Magma Demon King, then suddenly swooped down, its claws engulfed in ghostly black flames, reaching for the Demon King's head.

The Magma Demon King reacted swiftly, raising its head abruptly, meeting the Black Flame Lord with its hardened skull.

Once again, they collided, producing a loud bang.

The Black Flame Lord was sent flying backward from the collision, while the Magma Demon King received a claw that left a crack on its lava armor.

The area affected by the battle expanded further and further; the mountains of Flame Mountain continuously collapsed under their impacts, countless burning boulders tumbling down, crashing towards the base.

The demons on the mountain were in dire straits; whether they were low-level demons or high-tier Tier Six demons, all were caught in the midst of this Tier Seven Demon King clash.

Some low-level demons were burned to ashes by the flames, leaving not a trace; some Tier Six demons were turned to ash by the falling black flames; others were engulfed by magma, turning into a pool of pus in their painful wails, suffering heavy casualties.

The Demon Source at the center of Flame Mountain was also affected, as the ceaseless energy impacts rendered the once-stable demonic qi turbulent and restless, the vortex trembling violently, like a bomb about to explode, at any moment on the verge of collapsing.

The space around the Demon Source began to warp, and some low-level demons who approached were instantly torn to pieces by the twisted space.

As the battle continued, the two Demon Kings were fighting with blood-ridden eyes, having completely lost their senses.

The Black Flame Lord no longer held back, pushing the black flames within to their utmost, becoming a black fiery meteor, surrounded by countless black flaming halos, exuding an aura of destruction, crashing towards the Magma Demon King.

The Magma Demon King also fought with abandon, condensing the lava power throughout its body onto its fists, the magma on its fists roiling incessantly, forming two gigantic lava vortexes, charging towards the Black Flame Lord with unyielding momentum, smashing fiercely.

"Boom——!!!"

A tremendous earth-shattering noise echoed as the two collided fiercely.

The horrific energy erupted instantly, forming a huge energy mushroom cloud, soaring into the sky, dyeing the heavens a dark red. The energy shockwave spread in all directions, causing the ground to collapse, the mountains crumbled, Flame Mountain collapsed under the impact of this energy, leveling the entire mountain, leaving only a massive crater.

The Demon Source was thoroughly destroyed in the explosion, black demonic qi gushing out like a flood, forming a giant black smoke column in the air, then dissipating into nothingness.

The destruction of the Demon Source made the demonic qi throughout the Infernal Demon Sea chaotic, countless demons felt this change, plunging into panic.

Boom boom boom!

The battle reached a fever pitch, the two Demon Kings had lost all sanity, solely intent on killing each other.

It's unknown how long it lasted, the battlefield a complete wreckage.

The Black Flame Lord lay on the ground in a sorry state, its wings burned away, leaving only half on each side, the remaining parts still smoldering, its left arm reduced to ashes, revealing the white skeleton.

Its body covered in wounds deep enough to see the bone, black blood coursing from the wounds, its breath greatly diminished, like a candle in the wind, any moment ready to be extinguished.

The Magma Demon King wasn't faring much better, one eye burned to a hollow, molten lava flowing steadily from the hollow eye socket. Half its body scorched black, the originally thick lava armor now dilapidated, exposing the equally charred muscle tissue. It knelt on the ground, each breath a painful gasp, its breath greatly diminished.

The two once-unmatchable Tier Seven Demon Kings now mutually devastated, amidst these ruins, only the heavy breathing remained, seemingly recounting the epic battle's brutality.

Around lay deadly silence, only occasionally interrupted by falling rocks, adding a touch of desolation to the wasteland.

Just then, a mysterious figure silently appeared high above, witnessing the scene below, a slight curve of a successful scheme playing at his lips.
