To comprehend all laws and attain immortality

The earth roared and trembled; another fierce battle was about to begin.

Chang Yuan tightly bound the Soul Devouring Beast King's neck like a black iron chain, straining to tighten it.

Taking advantage of the opportunity, Hulu pounced forward, its claws tearing fiercely at its chest, ripping off large chunks of stone armor. Just as it was about to suck the bright red blood, it was kicked in the chest by the Beast King, flying backward like a boulder with a broken string, crashing down and collapsing half of the mountain, where it was completely buried by glacial debris.

Hulu barely managed to push aside the rubble, but before he could get up, Chang Yuan was forcibly ripped off his neck by the Beast King and slammed down on it.

"Bang!"

With a muffled thud, the gourd was knocked to the ground again, causing excruciating pain in his chest, almost suffocating him.

Su Nanzhi also sensed the critical situation. Looking down into the abyss below the tree, she turned and gritted her teeth, saying, "Fellow Daoist, please wait here. I'll go and help!"

She naturally saw the stone tablet as well, and was unwilling to leave just like that.

Just then, Gu Fan grabbed her and said in a deep voice, "Wait, I think I've found a way to break the deadlock."

His tone was calm and composed, without the slightest hint of panic, instantly stabilizing Su Nanzhi's mind.

Although Hulu and Changyuan were at a disadvantage, they still managed to tear through the Beast King's defenses with brute force. Large pieces of rock-like scales peeled off its body, revealing the flesh underneath that shimmered with a bright red spiritual light.

In fact, Gu Fan had already noticed something was wrong when he received the blood of the Soul-Devouring Beast earlier.

The blood flowing from the Soul-Devouring Beast was not ordinary beast blood; it had no bloody smell whatsoever. Instead, it resembled a thick, mellow spiritual liquid. Moreover, there was no sign of internal organ pulsation within its body; only the meridians throughout its body carried surging spiritual energy.

As a cultivator of the Creation Lineage, he vaguely sensed at the time that this Spirit Devouring Beast was definitely not something born naturally from heaven and earth.

At this moment, Gu Fan's eyes narrowed, and he quietly activated his Myriad Manifestations Dharma Eye.

The crisscrossing meridians, under the Dharma Eye, transformed into a flowing rune diagram, which bore a striking resemblance to the Return to Primordial Runes that he had been studying day and night!

Gu Fan suddenly understood: 'The Spirit-Devouring Beast was created by the Master of the Yin-Yang Palace using Yin-Yang magic; its essence isn't a demonic beast, but rather some profound magical technique!'

Why can the Soul-Devouring Beast devour magic?

Why are there no male or female Devouring Beasts?

Why are there no cubs in the canyon nest?

Once you understand this, all your doubts will be resolved.

Gu Fan's gaze was fixed on the center of the rune diagram.

That place is the core hub for the flow of meridians, and also the only fatal weakness of the Soul-Devouring Beast King!

......

On the other side, Hulu and Changyuan struggled to their feet, staring at the Soul Devouring Beast King with fierce light in their eyes, roaring as they charged forward.

Just then, Gu Fan's voice transmission suddenly entered their minds.

The two paused, instantly understanding, a resolute glint in their eyes.

The Soul-Devouring Beast King had already launched a fierce attack. After running two steps, it flapped its wings and leaped up, bringing a foul wind as it descended from the sky, its sharp claws aimed straight at the gourd.

Hulu and Changyuan swiftly dodged the sharp claws, one to the left and one to the right. They then pounced simultaneously, biting the beast king's forelimbs tightly and dragging it backward with all their might, forcibly pulling the Soul Devouring Beast King upright.

Just then, a dazzling sword light suddenly shone!

Su Nanzhi understood Gu Fan's meaning and poured all her magic power into the short sword without releasing any spiritual light. The sword's edge emitted a chilling, sharp light, like a golden lightning bolt breaking through the air.

The sword light flashed and disappeared in an instant, so fast that only a blur remained.

"bite--"

The Soul-Devouring Beast King trembled violently, and a small hole was torn open in the center of its chest, from which viscous spiritual liquid gushed out.

The cavity wasn't large, far less noticeable than the wounds inflicted by the gourd and Chang Yuan, but it was precisely the core hub where its meridians flowed. The Beast King let out a resentful roar, its aura instantly dissipating, and it slowly collapsed to the ground, lifeless.

"D-It's done?"

Su Nanzhi stared wide-eyed, her face filled with disbelief.

Just now, she took a desperate gamble, relying entirely on Gu Fan's guidance—your private mobile library, accessible anytime—and actually killed that arrogant and ferocious beast with a single sword strike.

She turned to look at Gu Fan, a hint of reverence even rising in her bright eyes.

This wasn't the first time she had witnessed Gu Fan's mysterious nature.

"Splash!" "Splash!"

With the death of the Soul-Devouring Beast King, Hulu and Changyuan were also completely exhausted and collapsed to the ground.

Chang Yuan shouted in a hoarse voice, "Boy, how many years has it been since I've suffered like this!"

"Thank you for your hard work, senior."

Gu Fan spoke in a deep voice, nodded, and walked straight toward the gourd without stopping.

Although Changyuan's scales and armor had fallen off and its body was covered with claw marks, none of them were deep. This was due to both its strength and its rich combat experience.

But gourds are different.

It is usually mischievous and likes to act childishly towards Gu Fan, but once it receives an order, it will do its best and disregard its own safety.

That's why it was the most seriously injured. It had been holding on with a fighting spirit, but now that it was exhausted, it could hardly even get up.

After examining the gourd, Gu Fan walked to the beast king's corpse, took out the jade bottle, and caught the blood flowing from the hollow in its chest until it all stopped.

This blood had no bloody smell, and its spiritual energy was so pure that it was enough to draw a third-tier spiritual talisman; it was excellent talisman ink.

Then, he turned around and walked to the gourd, pouring bottles of blood into its mouth without hesitation.

"Gulp, gulp..."

Hulu gulped down several bottles before finally managing to sit up, quickly shrinking to about two feet in size. He snuggled into Gu Fan's arms and fell asleep immediately.

Gu Fan gently stroked its back and stuffed a healing pill into its mouth. Seeing that the wound on its chest was gradually closing and the bleeding had stopped, he felt relieved and put it into the spirit beast pouch.

On the other side, Chang Yuan, without needing Gu Fan's prompting, got up on his own, picked up a bottle of beast king's blood, and drank it heartily.

"Slow down, senior, there's still quite a bit left." Gu Fan chuckled upon seeing this.

Chang Yuan snorted coldly: "You're actually quite generous today!"

Most of the blood was fed to the gourd. Gu Fan kept two bottles as reserves, and the rest went into Chang Yuan's mouth.

Su Nanzhi had no objection to this.

After Chang Yuan also retreated into his spirit beast pouch to digest the spiritual liquid, the spiritual light of the remnant body of the Spirit Devouring Beast King gradually dissipated, eventually turning into a pile of ordinary rocks.

......

Beneath the ancient tree, in the pitch-black abyss.

Following the golden light, Gu Fan and Su Nanzhi slowly descended.

After descending a hundred feet, the golden light became even more dazzling, and the third transmission stele suddenly appeared before their eyes. On the stele, the Daoist text of the second part of the "Innate Two Elements Transformation and Divine Evolution Chapter" slowly floated.

Standing in front of the stone tablet, Gu Fan frowned slightly, suddenly thinking of the Gu brothers.

Along the way, they never saw any trace of the two again.

"Fellow Daoist Su, do you think the Gu brothers might have also been here?" he asked in a deep voice.

Su Nanzhi was taken aback upon hearing this, then shook her head: "It shouldn't be. Although the brothers are strong when they combine their powers, they only use Yin-Yang magic. Without a powerful spirit beast like you to assist them, those magic spells would only become nourishment for the Devouring Spirit Beast King..."

Su Nanzhi stopped mid-sentence and couldn't continue.

She paused mid-sentence, a flash of inspiration crossing her eyes, and exclaimed, "Could it be that the reason this Soul-Devouring Beast King is so strong is because they fed it?"

Gu Fan nodded heavily: "That's most likely the case."

He had long harbored doubts.

A late-stage third-tier beast king capable of devouring spells—if he hadn't had two third-tier spirit beasts to restrain him and hadn't used his Myriad Manifestations Eye to see through his weaknesses, even a late-stage Golden Core cultivator might not have been able to kill him.

But he did not believe that the Gu brothers were dead.

Given their cunning and strength, even if they couldn't win, escaping would be no difficult task.

A cold glint flashed in Gu Fan's eyes as he said in a low voice, "You'd better not let me catch you."
