"Boom!"

The massive halo surrounding them trembled fiercely after forcibly enduring Yang Yan's strike.

Manhattan stared at the scene in shock, his mind blank.

This was the barrier he believed to be invincible!

He had expended countless resources and time, secretly constructing the array in the Arctic, all for this very moment.

How could this happen?!

As the light screen quaked like breaking ice, fragments began to fall from the barrier.

"No! This is impossible! Absolutely impossible!"

Manhattan widened his eyes, shouting hoarsely, unable to believe the sight before him.

"Demon Monarch! Quick! Stop him! Stop him!"

Manhattan pointed at the advancing Yang Yan and shrieked, while he hurriedly retreated in fear.

The Nine Netherworld Demon Monarch appeared reluctant.

He knew the terror of Yang Yan.

Yet, Manhattan was crucial to the Demon Race's plans and couldn't die—at least not yet.

Especially now, the Celestial Demons desperately needed his cooperation.

Otherwise, breaking through the Heavenly Dao Barrier with their power would inevitably take more time and cost.

They could wait no longer.

"Damn!"

Seeing Yang Yan charging forward, the Nine Netherworld Demon Monarch gritted his teeth and met him head-on.

Manhattan's face changed drastically as he quickly retreated.

The Nine Netherworld Demon Monarch, shrouded in demonic energy, recklessly charged at Yang Yan, which caught him off guard.

It seemed the Demon Race highly valued Manhattan.

In an instant, Yang Yan's killing intent intensified.

If that was the case, he'd ensure Manhattan was left behind today!

"Hehe! Defeated opponent, haven't I hurt you enough?"

Yang Yan sneered, mocking.

Last time, he had accidentally let the Nine Netherworld Demon Monarch escape, vowing next time to kill him outright.

Unexpectedly, they met quickly, and without fear, the Demon Monarch charged in, leaving Yang Yan not holding back.

"Insignificant human, if my power weren't compromised, you wouldn't dare be so arrogant!"

The Nine Netherworld Demon Monarch jumped in rage, his right fist carrying tremendous force.

Boom!

A mass of demonic energy tore through the air, crashing towards Yang Yan with violent momentum.

Yang Yan remained unmoved, standing his ground.

Only when the Demon Monarch's fist was close did Yang Yan swiftly strike back.

Incredibly fast, outpacing the opponent!

Boom!

Two mighty forces collided, and a sound like a nuclear explosion echoed in the air.

"Kill!!!"

At this moment, Manhattan's densely packed troops began an all-out charge.

Gongsun Ruyan and others glanced at the sky battle and rushed forward to join the fray.

Only Sass stood at the rear, anxiously watching the clash between Yang Yan and the Demon Monarch.

After the strike, Yang Yan stood his ground, not taking a step back.

Meanwhile, Nine Netherworld had flown back hundreds of meters, stopping now.

Demonic energy surged around him, healing the damaged body.

Yang Yan pointed at the Demon Monarch, raised his eyebrows, and said disdainfully:

"Your Demon Race really is like an unkillable cockroach, your self-healing ability is strong."

The Nine Netherworld Demon Monarch didn't understand what cockroach meant, but he sensed the ridicule in Yang Yan's words.

Gritting his teeth, he suddenly smiled at Yang Yan:

"You're not feeling well now, are you? Insignificant human, succumb to the Demon Race's assimilation! I'll torment you later!"

"Hmm?"

Yang Yan's eyes flickered with confusion.

Suddenly, Sass's voice echoed loudly from the rear:

"Yang Yan! The demonic energy has entered your body. If you don't find a way to expel it quickly, you might be slowly assimilated!"

What the heck?

Though Yang Yan didn't quite understand, he quickly checked his body's condition.

When he punched earlier, the demonic energy on the Demon Monarch's fist seemed to halve upon contact.

Did it enter his body?

"I'll help you!"

Sass gestured, sending a sacred white light into Yang Yan's body.

The white light illuminated Yang Yan internally, faintly radiating outward.

"What's this?"

The Nine Netherworld Demon Monarch's face darkened intensely.

He stared at Sass, his gaze sharp with hatred, wishing to tear him apart.

Sass remained unfazed.

He had absolute faith in Yang Yan.

Though the Demon Race was formidable, the Demon Monarch was badly injured now, unable to exert his full power, hardly a threat.

Indeed, under the sacred light's illumination, the black demonic energy had nowhere to hide.

Yang Yan noticed the two energies battling within his body, fiercely consuming one another.

However, the dark demonic energy was evidently at a disadvantage, slowly dissipating.

With a target, Yang Yan wasn't idle.

Concentrating his mind, he wrapped the demonic energy within his own power, forcibly expelling it.

After completing this, Yang Yan smiled back at Sass:

"Elder Sass, just for this gesture, I'll definitely save the Dusk Race."

Upon hearing Yang Yan's words, Sass was visibly moved, promptly shouting:

"Moonlight Emperor, even ordinary members of the Dusk Race can perform this!"

Yang Yan was delighted by Sass's response.

Squinting, he again fixed his gaze on the Nine Netherworld Demon Monarch with amusement.

In an instant, a cat-and-mouse atmosphere started to spread across the scene.

"Nine Netherworld Demon Monarch, should I kill you, or capture you to interrogate for information on the Demon Race?"

Yang Yan said with a smile.

"Boy, you dream!"

The Nine Netherworld Demon Monarch trembled and roared.

Simultaneously, he swung his right hand, a massive black fireball emitting scorching brilliance appeared out of thin air.

"Yang Yan, be careful! It's the Demon Race's Lifebound Demon Flame! He's gone mad!"

Sass reacted in shock, urgently warning.

Fearing Yang Yan might confront it head-on.

"Lifebound Demon Flame?"

Before Yang Yan could grasp its meaning, the flame rapidly closed in.

Standing still, the Nine Netherworld Demon Monarch's face turned pale.

His demeanor weakened, no longer resembling a mighty figure.

Yet, the Demon Monarch laughed brazenly.

Especially as the flame neared Yang Yan, his laughter grew more wild.

Yang Yan was ready to slice the so-called Demon Flame apart.

"Bang!!!" 𝙛𝒓𝓮𝙚𝔀𝒆𝒃𝓷𝒐𝓿𝙚𝓵.𝙘𝒐𝒎

The flame seemed to have a mind of its own, exploding suddenly before Yang Yan.
