Sass stood in place, dumbfounded, muttering to himself:

"It's over, it's all over, it's all over now..."

The Lifebound Demon Flame is the concentrated energy and half the potential abilities of the Demon Race, with unimaginable lethality.

However, using it will cause the Demon Race to drop several realms in power, making it a mutually destructive ability.

The enormous noise attracted everyone's attention.

Whether it was Gongsun Ruyan and the others or the hundreds of subordinates on Manhattan's side, all eyes were fixed on the explosion.

Gongsun Ruyan and the others clearly saw the danger, the hand holding the sword trembling incessantly.

Zhuge Wushuang was the fastest to react, charging forward instantly, with his Longsword aimed directly at the Nine Netherworld Demon Monarch.

"Seeking death!!"

The Nine Netherworld Demon Monarch shouted fiercely, and demonic qi surged from his body.

"Wushuang!"

Yang Yan's voice suddenly rang out, though it seemed ethereal:

"This head is mine to take!"

Zhuge Wushuang abruptly halted, casting a somewhat suspicious glance in Yang Yan's direction.

Yang Yan appeared all in black, his clothes no longer in sight.

He looked a bit disheveled, but seemed unharmed.

"You're doomed."

Yang Yan looked at the Nine Netherworld Demon Monarch, who was in shock, and pronounced each word clearly.

In a brief moment, the Demon Monarch's shock turned to fear.

He no longer hesitated, transforming into a cloud of black mist, hastily fleeing!

Manhattan was important, but his life was even more so!

As the advance troop of the Demon Race, he was the first to break through the Heavenly Dao Barrier and reach Earth, indicating the extraordinary status of the Demon Monarch.

However, crossing the Heavenly Dao Barrier had cost him dearly.

Now, even if he fled with all his might, his speed was just average to Yang Yan.

Yang Yan raised his right hand, and Star Night slashed down fiercely.

Whoosh!

A blade that was visible to the naked eye whizzed out, chasing after the fleeing Nine Netherworld Demon Monarch at incomparable speed.

Slash!

The cloak on the Nine Netherworld Demon Monarch immediately split in two. 𝘧𝑟𝑒𝑒𝘸𝘦𝘣𝑛𝑜𝘷𝑒𝓁.𝘤𝘰𝓂

Then, a massive wound appeared from top to bottom.

White, ghastly bones and his abdomen were exposed to the air.

A torrential rain of blood began to fall, drenching dozens of Manhattan's subordinates below.

The Demon Monarch stayed momentarily in the air for a few seconds, mouth agape as if to speak.

Finally, he just slightly opened his mouth, unwillingly glancing at the sky before his body heavily crashed down.

"Star Night——"

Yang Yan looked at the knife in his hand and smiled wanly.

Only then did Zhuge Wushuang notice that Yang Yan's face was somewhat pale, his complexion changing as he immediately rushed forward.

"It's nothing."

Yang Yan lifted his head to glance at the nearby Zhuge Wushuang, forcing a difficult smile.

"Sigh——"

Sass sighed heavily, sitting cross-legged in mid-air, uttering strangely pronounced words as if chanting something.

Meanwhile, he slowly raised his right hand, and a white light whistled out, striking Yang Yan accurately and enveloping him swiftly.

The injuries in Yang Yan's body began to heal rapidly at a visible pace, his aura becoming increasingly stable.

A moment later, Sass withdrew his hand, falling powerlessly from the sky.

"You!"

Zhuge Wushuang saw Yang Yan's injuries improving, but Sass had stopped, turning in mild anger.

She happened to see Sass falling and was about to rush to help.

But Yang Yan's speed was much faster than hers.

In an instant, he disappeared from his original spot, appearing beside Sass and catching him firmly.

He then floated gently to the ground, carefully placing the nearly unconscious Sass.

"The Dusk Race truly lives up to its reputation; I'm already more than halfway recovered."

Yang Yan said with a smile.

Elder Sass, now drenched in sweat, sat weakly on the ground with a bitter smile:

"Moonlight Emperor, I've done my best. With injuries like yours, without heavenly materials and earthly treasures or long-term recuperation, it's hard to recover fully."

To be honest, Sass was filled with immense astonishment towards Yang Yan.

Living for so many years, it was his first time knowing someone could survive the Lifebound Demon Flame of the Demon Race.

Moreover, the gap between them wasn't vast, both being in the Emperor Realm.

Even knowing the Nine Netherworld Demon Monarch was grievously injured, the Lifebound Demon Flame was still formidable, and Yang Yan enduring it indicated his strength.

"How long until you fully recover?"

Yang Yan could see that Sass had exhausted much effort in aiding him, and couldn't help but ask out of concern.

Though Sass had his reasons, hoping Yang Yan might help save the Dusk Race with full strength, a favor is a favor, and Yang Yan remembered it.

"About a few days for full recovery."

Sass weakly waved a hand, indicating he was fine.

"That's good."

Yang Yan nodded and turned back to the battlefield.

Gongsun Ruyan and Fu Changjian seemed stimulated, completely ignoring defense and engaging in frenzied slaughter.

After confirming Yang Yan was alright, Zhuge Wushuang hesitated a bit but then re-entered the battlefield.

These hundreds were definitely Manhattan's elite troops.

Each individual's prowess was formidable even outside, at least SSS-level battle strength.

The black aura emanating from them showed they had undergone special augmentation.

Precisely for this reason, Yang Yan and his side felt no qualms.

Sass had already warned that once tainted by demonic qi, these people's demon nature would only grow worse.

Eventually, they'd fully demonicize, turning into machines of slaughter.

However, the Ten Swords under Yang Yan, having fully liberated their strength, were all top-notch existences.

Especially now, with three swords combined, the so-called elite seemed utterly vulnerable.

"Kill!"

"Kill!!"

"Kill!!!"

The final shout came from Yang Yan, his energy the greatest.

With Yang Yan's participation, the battlefield became a one-sided massacre.

Once the dust settled, Yang Yan sheathed his blade, standing silently.

By then, he was dressed in new clothes, his complexion returning to normal.

Fu Changjian and his two companions, swords in hand, silently followed behind Yang Yan.

Judging by their aura, they were like unsheathed swords, chilling and glimmering!

"Manhattan, will you come out yourself or do I have to destroy everything here?"

Yang Yan stood there quietly, then gave a slight smile.

In his perception, he couldn't detect any presence.

No wonder Manhattan had appeared so confident before; he had to admit there was something eerie about this place.

Nonetheless, he continuously observed the situation, secretly releasing his Divine Sense to seal the area.

If anyone attempted to leave, he would definitely know.

After a full minute of silence, Yang Yan's powerful Divine Sense had nearly turned the place upside down, yet he found nothing.

From start to finish, Manhattan showed no reaction.

"If that's how it is, then I'll just destroy the place and be done with it."
