The Beast King let out a roar, and the gigantic black sphere in front of it smashed straight towards the center of the battlefield.

At this moment, the Fire Feather Golden Eagle simultaneously released a fireball to intercept.

Seeing this, the beasts lost all will to fight. They hurriedly retreated, gazing at the Beast King with terror-filled eyes.

They were puzzled, risking their lives for the enemy, yet in the end, the enemy wanted to slaughter them.

A loud explosion rang out, and terrifying energy waves spread directly from the battlefield center.

Except for the Monarch-level Guardian Beasts, able to withstand it unharmed, all other Guardian Beasts were flung away by the energy.

Seeing this, everyone hurriedly ordered their Guardian Beasts to retreat.

The entire battlefield was emptied in an instant.

The Beast King looked at the retreating Star Beasts and directly lashed its tail to start slaughtering the Lord Level and below Star Beasts.

Seeing this, Wang Haichuan couldn't help but frown. The Beast King's actions left him baffled; even if its subordinates fled, it shouldn't slaughter them.

However, he had no intention of stopping it, since internal strife amongst enemies was favorable.

Yet, Wang Haichuan had a vague sense of foreboding without knowing why, and all he could do now was wait.

As time passed, the beast herd was quickly slaughtered to extinction.

At this moment, the Beast King's eyes were filled with bloodthirsty madness.

It raised its head and let out a roar, and the Iron Feather Divine Eagle, which had been fighting the Double-Winged Demon Tiger, suddenly flew over.

Its claws held a transparent crystal stone the size of an adult's fist.

Seeing this, Wang Haichuan frowned, as he didn't recognize the item, but the deathly aura it emitted was extremely unsettling.

"Not good, quickly stop it," Elder Wu exclaimed.

Without hesitation upon hearing these words, Wang Haichuan immediately ordered the Fire Feather Golden Eagle to attack, but it was too late.

The Iron Feather Divine Eagle had already flown above the Beast King and threw the transparent crystal stone towards it.

Seeing this, the Beast King twisted its serpent body, bouncing its massive snake form upwards, and opened its blood-red maw, swallowing the transparent crystal stone whole.

Unable to stop it, Wang Haichuan quickly turned to ask, "Elder Wu, what is that?"

With a troubled expression, Elder Wu replied, "It's an Earth Rank Lower Grade Undead Crystal. Once a Star Beast ingests it, it can absorb souls from its surroundings and forcefully transform into an Undead Element, with a chance to enhance its quality. The Beast King intends to use it to break through to King Level."

Hearing this, Wang Haichuan's expression suddenly changed. Everything from the beast tide to the recent massacre was a setup for this moment.

And everyone was merely a tool for its ascension to King Level.

"Is there any way to stop it?" Wang Haichuan asked sternly.

Shaking his head, Elder Wu replied, "During the transformation, the Undead Crystal forms an Undead Barrier. Even King Level Guardian Beasts struggle to break it. All we can do now is wait."

"Wait for what?" Wang Haichuan asked sternly.

"Wait until it completes its transformation. If its quality isn't enhanced, then we might have a chance to kill it. Whether we survive depends on luck," Elder Wu said with a sigh.

At this moment, the Beast King raised its head, a poignant and harrowing screech emanating from its mouth, enveloping it in an invisible barrier. Then, a multitude of souls floated across the battlefield, drawn irresistibly towards the Beast King's body, including those of Star Beasts and humans.

The Beast King's agonizing cries grew louder, as its massive serpent body rolled within the barrier, crashing into the ground repeatedly, trying to alleviate its pain.

Witnessing this, everyone displayed shocked expressions. Apart from the Beast Masters on the battlefield, no one else knew what was happening.

However, seeing the Beast King's state left everyone extremely uneasy.

At this moment, Elder Li seemed to recall something and urgently spoke up, "Guardian Beasts with Purification Skills from the Light Element could purify these souls, potentially disturbing the Beast King and causing its transformation to fail."

Upon hearing this, Wang Haichuan was overjoyed. He quickly issued orders for all eligible Guardian Beasts to immediately start purifying the souls.

But after the order was transmitted, only a dozen or so met the criteria.

Light Element Guardian Beasts were already scarce, and those with Purification Skills were even rarer.

Now, it was just a matter of trying anything in desperation, purifying what they could, rather than waiting to die.

As time passed, the Beast King's cries grew louder, its soul absorption rate accelerated, its range expanding continuously.

The Beast King's body had already started to change; its originally dark scale armor began to fall off, its flesh gradually dissolving, some parts even revealing ghastly white bones.

Though the Beast King appeared extremely pitiful, its aura showed no sign of diminishing; instead, there was a faint sense of breakthrough.

This made Wang Haichuan's frown deepen, his expression growing increasingly grim.

He attempted several attacks on the barrier, but the results matched Elder Wu's predictions, leaving him helplessly staring at the Beast King, praying for its failed ascension.

Time ticked by, the Beast King's flesh completely dissolved, leaving only a stark white skeletal snake, its cold snake pupils replaced by twin blue flames.

"Roar"

A roar of unwillingness erupted from within the barrier, indicating the Beast King had completed its transformation.

And the barrier hindering everyone vanished in an instant.

Seeing this, Wang Haichuan displayed instant joy; although the Beast King had completed its transformation, luck seemed to have abandoned it. Its quality hadn't improved; otherwise, it would already have stepped into King Level.

"All Monarch-level Guardian Beasts, heed my orders; attack with all your might. We must prevent it from absorbing any more souls, or we'll all die if it advances to King Level," Wang Haichuan said sternly.

Listening to this, everyone nodded gravely.

As the Guardian Beasts charged forward, the Ghost Fire flickered in the Beast King's eyes as it let out a low growl, summoning all the distant Star Beasts.

The battle ignited again, but this time the Beast King did not initiate an attack. Twisting its body, it floated in mid-air.

It opened its massive maw, drawing forcefully towards the distant corpses, and dozens of souls were sucked into its mouth at once.

It had reached the Monarch-level Peak aura, showing signs of increasing further.

Seeing this, Wang Haichuan was terrified to let it absorb anymore, urgently commanding the Fire Feather Golden Eagle to attack the Beast King.

In response, the Beast King showed no interest in engaging with Wang Haichuan. With a flicker, it charged towards the corpse-laden trap.

After transforming into the Undead Element, the Beast King's speed experienced a qualitative leap, now possessing the ability to fly. With intent to evade, the Fire Feather Golden Eagle couldn't affect it.

In the blink of an eye, it appeared over the trap, where roughly two thousand Star Beast corpses lay. If all these souls were devoured, it might break through its shackles, stepping into the King Level it desperately coveted.
