I'm in Yellow Maple Valley, and I have one equipment slot!

"Damn human! I'll kill you!!!"

Inside the great formation, the level eight giant bird heard the mournful cries of its race outside and became extremely enraged!

It suddenly transformed into human form—the old man in black reappeared, with only one and a half black wings remaining on his back, and the wound on his stomach was hideous and terrifying. Although he had forcibly stopped the bleeding with his demonic power, his internal organs were still vaguely visible, a shocking sight!

At this moment, his killing intent towards Zhou Yuan had reached its peak!

"Break it!"

The old man in black roared and waved his hands repeatedly, sending streaks of black light crashing wildly against the array's protective barrier!

Under a series of attacks, the already crumbling Ninefold Sealing Pill Formation finally gave way.

"boom--!"

The light shield shattered completely!

The array plate shattered, the array flags broke, and this array that Zhou Yuan had painstakingly crafted over many years was destroyed in an instant!

The old man in black rushed out of the formation, his blood-red eyes fixed on Zhou Yuan, as if he wanted to devour him alive!

"Human! I will devour your flesh, bite by bite! I will grind your bones to dust—!"

He roared, flapped his wings, and transformed into a black streak of light, rushing straight towards Zhou Yuan!

However, the moment he broke through the formation—

Zhou Yuan was already fully focused and ready with his trump card!

Spirit Prison!

A dark black prison mark shot out from Zhou Yuan's palm!

This is a high-level low-tier spell.

It needs to be fused and refined by combining pure spiritual power with a portion of divine soul power.

The Prison Seal possesses some intangible and intangible characteristics, giving it a strong ability to penetrate physical defenses and energy shields, and even ignoring defenses to a certain extent!

Upon seeing the black light approaching, the old man in black instinctively waved his hand, unleashing several wind blades in a barrage!

However, the wind blade passed straight through the prison seal, as if it were just an illusion!

"What?!" The old man's pupils contracted.

He hurriedly activated several more wind walls to block in front of him.

However, the black prison seal passed through without any hindrance, as if those wind walls didn't exist at all!

What the hell is this thing?!

The old man was terrified and tried to dodge.

But the speed of the prison seal suddenly increased dramatically, and it instantly entered his body!

"What?!"

The old man in black looked down at his body and found no wounds, nor did he feel any pain.

But the next moment, his expression changed drastically!

His demonic power—was imprisoned!

After the black prison seal entered his body, it transformed into an invisible "spiritual prison," sealing all the demonic power nodes in his body!

Despite possessing the formidable physical body of an eighth-level demon beast, he couldn't mobilize a single trace of demonic power at this moment!

"Go to hell!"

Zhou Yuan had been waiting for this moment!

He flicked his finger, and a beam of blood shot out!

Blood Spirit Diamond!

This is a secret technique he obtained from the Yue Emperor, which compresses the spiritual power in his body dozens of times and condenses it into a physical form of magic power. He usually keeps it within his body and activates it instantly when facing an enemy!

This technique is incredibly fast and focused on breaking through defenses, making it an excellent means of ambushing and finishing off enemies!

A flash of blood!

It was so fast that even divine sense could hardly detect it!

The old man in black had just broken free from the "Spirit Prison" and hadn't even had time to feel relieved—

"puff!"

The Blood Spirit Diamond pierced his skull with unparalleled precision!

His movements came to an abrupt halt, and the fierce light in his eyes dimmed at a visible speed, finally dissipating completely.

The corpse of the eighth-level transformed demon fell from the sky and crashed heavily onto the scorched earth, kicking up a cloud of dust.

"call……"

Zhou Yuan let out a long breath, and his tense nerves finally relaxed slightly.

But he did not go forward immediately.

The ancient white jade mirror still maintained its defensive light shield, and its protective aura had not dissipated.

He stood cautiously in place, quietly observing the corpse for a moment.

There was no movement.

Zhou Yuan was still uneasy.

He raised his hand and unleashed a massive fireball that struck the corpse.

Flames roared and engulfed the corpse.

The body remained motionless and unresponsive.

Zhou Yuan was finally completely relieved.

He stepped forward and waved his hand to extinguish the flames.

The surface of the corpse was only slightly charred. After all, it was an eighth-level demon beast with a strong body, and a mere fireball could not burn through it in a short time.

But at this moment it was a real corpse and no longer posed any threat.

Zhou Yuan took out the Green Radiance Sword and carefully dissected the hideous head.

Several feet away, he used his magic to condense an invisible hand, reached into the skull cavity, and took out a fist-sized, pitch-black demon core from the bloody mess.

The demon core of an eighth-level demon beast!

A glint of excitement flashed in Zhou Yuan's eyes.

However, at this moment—

A phantom, miniature black bird suddenly leaped out from the demon core, heading straight for Zhou Yuan's face!

That is the essence of this transformed great demon!

It wants to possess Zhou Yuan!

"I've been on guard against you for a while now!"

Zhou Yuan sneered, showing no sign of panic.

How powerful was his divine sense? Its terrifying strength surpassed that of the early Nascent Soul stage. How could this wisp of severely injured and dying essence possibly shake it?

A layer of cyan light instantly covered his palm, and with a swift movement, he firmly grasped the mini black bird that had charged at him!

The spirit struggled and screamed wildly in his palm, but like a caged bird, it was all in vain.

Zhou Yuan took out a blank jade bottle, stuffed the essence into it, and then used his magic to set up several layers of restrictions at the mouth of the bottle to ensure that it could not escape.

Now, the problem is completely solved.

He put away the jade bottle and turned his gaze to the black demon core in his hand.

However, when his divine sense probed into it, his brows furrowed slightly.

The demonic power within this demon core has already been largely lost.

That makes sense—the level eight demonic bird first fought a fierce battle with the blue-robed old monster, sustaining serious injuries, and was then ambushed, trapped, severely wounded, and finally killed by him. Throughout the process, it consumed a huge amount of demonic power and lost countless amounts of blood.

It's already incredibly fortunate that this demon core was preserved.

"A demon core with such severely depleted demonic power is probably no longer of any value for alchemy," Zhou Yuan said with some regret.

But instead of discarding it immediately, he had a thought and equipped it to his sixth equipment slot.

A pale blue light screen appeared in my mind:

[Equipment Slot 6: Crow Demon Core (Level 8)]

[Effect 1: Increases comprehension of Wind-attribute escape techniques!]

[Effect 2: Increases the chance of breaking through the Nascent Soul bottleneck!]

Zhou Yuan's pupils suddenly dilated!

Increase the chances of breaking through to the Nascent Soul stage!

Even if it's just a "slight improvement," even if the demon core loses most of its demonic power and its effect is greatly reduced.

But the weight of those few words is enough to drive any Core Formation cultivator mad!

Nascent Soul Formation—that is the ultimate goal that countless Core Formation cultivators strive for their entire lives but can never achieve!

Five hundred years of lifespan may seem long, but in the face of the insurmountable barrier of Nascent Soul formation, ninety-nine percent of Nascent Soul cultivators will perish along the way.

In the end, it turned into a handful of yellow earth.

This demon core, once equipped, can increase the chances of forming a Nascent Soul!

Even the slightest glimmer of hope is enough for Zhou Yuan to cherish like a treasure!

"Good! Good! Good!"

Zhou Yuan exclaimed "Good!" three times in succession, his heart filled with barely suppressed joy.

Although this trip to the outer seas was fraught with life-or-death crises like the one with the blue-robed old monster, the final harvest of this demon core that can increase the chances of Nascent Soul formation made it all worthwhile!

He carefully put away the demon core and was about to leave.

A mournful cry echoed from the sky.

The three level-six black demonic birds, their bodies covered in scorch marks and their feathers disheveled, finally managed to break free of the sea of ​​fire.

They hovered in mid-air, looking down at the king's corpse, and let out mournful cries.

The voice contained sorrow, anger, and even more so, endless despair.

Zhou Yuan raised his head, looked at the three level-six demonic birds, and a smile appeared on his lips.

"Since your king is dead, you may go with him."

His magical power had already been fully restored through the powerful enhancement of his equipment slots!

Zhou Yuan made a hand seal, and the two golden dragons condensed and took shape again!
