645: Both sides suffer heavy losses!

Boom!

Nine attacks struck the Formation diagram, erupting with a deafening roar.

The Bagua Formation Diagram trembled violently in an instant, and even the golden light upon it dimmed slightly, but it managed to hold firm in the end.

"Hmph, you do have some skill."

You Zhengyang sneered, his figure flickering as he instantly appeared above the Formation diagram. He reached out and grasped the air; the seal instantly shrank and returned to his palm, which he then slammed downward.

Immediately, a powerful Immortal Qi erupted from all around You Zhengyang.

"Shatter for me!!"

Rumble!!!

The other eight Elders also held nothing back, frantically driving the Immortal Qi within their bodies, clearly intending to end the battle quickly.

Crackle... pitch-black cracks began to spread across the surface of the Formation diagram, as dense as a spiderweb.

"Heavenly Demon Legion! Give it your all, we must hold! This Chaotic Soul Mountain is a vital location for our Sect; it must not be lost!"

Duanmu Qin's face flushed red, and the veins on his forehead bulged, clearly pushed to his limit.

Ten thousand members of the Heavenly Demon Sect roared in unison, pouring out their cultivation without reservation, desperately maintaining the operation of the Formation diagram.

Under the mutual stalemate, the Bagua Formation Diagram teetered on the verge of collapse, and at the final moment, it was ultimately broken through.

Accompanied by the sound of the Formation shattering, a massive surge of energy, guided by the seven Elders of the Heavenly Demon Sect, charged straight toward Chaotic Soul Mountain!

This single strike caused a hundred thousand Cultivators to perish on the spot!

Truly, human lives were like grass... Seeing the Formation broken in one hit, the Heavens Mandate Sect's eyes showed a flash of excitement. You Zhengyang led the charge toward the Heavenly Demon Legion, while the other eight Elders caught their breath and struck again!

One person sacrificed a blood-colored long saber, its blade wrapped with countless vengeful souls emitting shrill wails;

Another pinched a hand seal, summoning a vast army of skeletons that swarmed down toward the legion of ten thousand below;

Yet another directly burned their essence blood to perform a forbidden technique, their Aura skyrocketing several times over.

For a time, the sky above Chaotic Soul Mountain was shrouded in lights of various colors, with explosions echoing one after another.

The Void Realm collapsed inch by inch, revealing pitch-black cracks in time and space.

The violent aftershocks of energy swept down along the Formation; many Cultivators who were mining had no time to flee and were directly shaken into a bloody mist.

Screams, explosions, and the clashing of Magic Treasures intertwined into a symphony of death.

"Kill!"

The ten-thousand-strong legion of the Heavenly Demon Sect had also completely seen red.

Groups of hundreds formed battle arrays, turning into flows of black current as they charged fearlessly toward the nine Elders of the Heavens Mandate Sect.

An Elder of the Heavens Mandate Sect was besieged by hundreds of Supreme Realm Cultivators, his body blasted with several bloody gashes, but he only gave a savage laugh and opened his mouth wide to spit out a glob of black flame.

The flame instantly expanded, turning into a sea of fire that swallowed those hundreds of people whole.

Shrill screams rang out as those Cultivators struggled and rolled in the flames, turning to charcoal in the blink of an eye.

"Beasts!"

Duanmu Qin's eyes nearly split from rage as he shattered an immortal shield protecting a Heavens Mandate Sect Elder with one palm, followed by a punch to the opponent's chest.

Crack!

The sound of ribs breaking was clearly audible.

That Elder spat out a mouthful of blood and flew backward several hundred feet, slamming hard into the mountainside and smashing a huge crater into the hard rock.

"Heavenly Demon Sect! You've ruined my Heavens Mandate Sect's ten-thousand-year plan; today shall be a fight to the death!!!"

He spoke harshly, then simply wiped the blood from the corner of his mouth and charged forward once more.

The battle between the two sides entered a fever pitch.

Time passed minute by minute.

Half an hour later.

The Heavenly Demon Sect's legion of ten thousand had lost more than half its number, and the remaining soldiers were all wounded, their Auras withered.

The Heavens Mandate Sect side was not much better off.

All nine Elders were injured; two of them were severely wounded with unsteady Auras, clearly at the end of their rope.

Three others had basically lost the strength to fight further, their Auras incredibly weak, and even their Realms had dropped slightly.

One had already fallen... Duanmu Qin panted heavily, looking at the equally bedraggled You Zhengyang across from him, a hint of wariness flashing in his eyes.

Even with the advantage of terrain and the assistance of the ten-thousand-strong legion, they could only fight to this state.

The foundation of the Heavens Mandate Sect was truly unfathomable.

"You Zhengyang, if we continue to fight like this, both sides will only suffer!"

Duanmu Qin spoke in a heavy voice, attempting to call a halt to the battle.

You Zhengyang sneered and did not answer, instead raising his hand. In his palm, a glob of dark red light began to condense.

That was his trump card.

A forbidden technique.

Once used, his cultivation would skyrocket three times over for a short period, but the price was that for the next thousand years, he would be incredibly weak and could only go into secluded meditation within the Sect to heal.

Seeing this, Duanmu Qin's pupils suddenly constricted.

He no longer hesitated either, biting the tip of his tongue and spitting out a mouthful of essence blood onto a simple, ancient token floating before him.

The token instantly erupted with a dazzling golden light, and a vast pressure diffused from it.

That was a life-saving measure left by the Sect Master of the Heavenly Demon Sect.

It could summon a Clone of the Sect Master, possessing half a percent of his strength.

The Aura of both sides climbed to the extreme at this moment.

The surrounding Void Realm began to warp, unable to withstand this terrifying pressure.

You Zhengyang looked at the token in Duanmu Qin's hand with great wariness, his forbidden technique remaining unactivated for the time being.

"You Zhengyang!! What exactly do you want?! For a mere Chaotic Soul Mountain, is it worth your Heavens Mandate Sect risking your lives like this?! Won't this just benefit the Guiyuan Sect!"

Duanmu Qin suddenly roared, his voice tinged with urgency.

You Zhengyang's movements paused slightly as he looked at him coldly, the forbidden technique in his hand flickering, looking quite terrifying.

The other seven Elders also quietly stood behind him.

"I have no interest in Chaotic Soul Mountain at all!"

You Zhengyang said coldly.

Seeing this, Duanmu Qin spoke again:

"If that is so, Elder You, although we have grievances with your Heavens Mandate Sect, we haven't reached the point of a life-and-death struggle. Why have you suddenly attacked our door today, insisting on putting us to death?!"

Duanmu Qin asked through gritted teeth, his tone carrying a hint of incomprehension and anger.

"If there is truly some misunderstanding, we can sit down and talk! Why make things reach such a state, causing both houses to have their Origin Qi severely damaged?!"

Hearing this, a flash of mockery appeared in You Zhengyang's eyes.

"You stole my Heavens Mandate Sect's supreme treasure, and you're still putting on an act here?"

He smiled coldly, his killing intent increasing rather than decreasing.

"Duanmu Qin, do you take me for a fool?! If you hand over the stolen item, I will withdraw immediately!"

Duanmu Qin was stunned, then his expression became somewhat confused.

"What does Elder You mean by this? We have guarded this place for a hundred years and have never left Chaotic Soul Mountain, let alone stolen your Sect's supreme treasure! Could there be a mistake?!"

His voice carried a hint of urgency; he clearly was truly unaware of the situation.
