I established the Eternal Immortal Clan by taming beasts.

Using the same method, Lin Che and Qingxuan Realm Spirit then arrived at the area in the secret realm where the wood-attribute spiritual energy was most concentrated and pure.

In the very center of the island in the lake, where Kong Yinsang originally lived.

Here, following the profound methods recorded in the "Five Saints Blood Pact Spirit Forging Secret Chapter", Lin Che mixed his own essence and blood with his divine thoughts to condense an extremely complex "Five Spirits Blood Pact Seal".

They successfully established a unique "Origin Blood Pact" with the Azure Profound Realm Spirit, which is essentially closer to the innate wood spirit and controls the origin of the secret realm.

The wood element corresponds to strengthening a cultivator's liver.

The moment the blood pact was established, a pure, powerful, and infinitely vibrant elemental energy of the Wood element emanated from the Azure Profound Realm Spirit and surged into Lin Che's body through the blood pact channel.

Begin tempering the entire body's meridian system.

At first, excruciating pain, accompanied by an indescribable tingling and numbness, instantly spread throughout his body, as if thousands of ants were simultaneously gnawing at and probing all his meridians!

That was the Wood elemental energy forcefully washing over, expanding, and tempering his entire meridian system in the most brutal yet effective way.

Lin Che grunted, veins bulging on his forehead, but he gritted his teeth and used his secret technique to guide the power.

Seven days later, the persistent intense pain, soreness, and numbness gradually subsided, replaced by a strange warm sensation spreading deep within the meridians.

The originally tough but limited tendons and ligaments, under the continuous nourishment and forging of the Wood elemental energy, began to become more flexible and elastic, like an old vine giving birth to new branches.

Gradually, extremely elegant cyan spiritual patterns faintly appeared on the major tendons around Lin Che's body, appearing and disappearing intermittently.

With a slight exertion, he felt that the strength of his tendons and muscles and his endurance had increased by about half a percent compared to before!

With every movement, the transfer of power becomes smoother and faster, and the recovery speed is also significantly accelerated.

"This is just the beginning of the wood element tempering." Lin Che finished his practice, feeling the changes within his body, and was quite satisfied.

"Once we gather all five elemental beasts and form a complete five-element cycle, we can truly begin the systematic 'Five Saints Spirit Forging.' At that time, the comprehensive strengthening effect on the body will truly manifest, far surpassing what it is now."

On the very day that the wood element tempering began to show results, an unusual and violent fluctuation came from the volcanic region of the western part of the Qingxuan Secret Realm.

The transformation of the Yaren Beast has finally reached the most crucial and dangerous step!

……

Lin Che and the Hellfire Tiger were already waiting in the distance.

At this moment, the fur of the Yaren Beast had completely changed from dark gold to a suppressed dark red, as if lava was flowing inside its body, or as if it had been soaked in blood and dried up.

Even from a great distance, an extremely violent, ferocious aura, as if it were about to tear everything apart, rushed towards us, causing the surrounding air to distort slightly.

"It's about to begin!" Lin Che said in a deep voice, his expression serious.

As if to prove his words—

"boom!!!"

A deep, thunderous roar, like thunder from the earth's core, suddenly erupted!

The "Earthly Fiend Golden Spirit Eye," originally generated by the Azure Profound Realm Spirit, now seemed to be completely detonated by some kind of catalyst within the Yaren Beast!

The crimson lava, streaked with dark gold threads, erupted forth with a thunderous roar.

It transformed into a thick pillar of fire, several meters in diameter, instantly engulfing the crouching figure of the Yaren Beast!

At the same time, the various third-order spirit ores and metal scraps that Lin Che had piled up around the Yaren Beast beforehand, like small mountains, all emitted a buzzing tremor as if they could not bear the weight!

The pure golden spiritual energy and the sinister military aura accumulated over the years inside the ore were forcibly drawn away by the molten gold evil fire and the suction force emanating from the bloodline of the Yaren beast.

Transforming into countless streams of energy, some as dazzling as golden rainbows and others as dark as filthy blood, they surged wildly towards the central pillar of fire, like rivers flowing into the sea, and entered the body of the Yaren Beast!

"roar--!!!"

Even though it had already prepared itself to endure inhuman pain, the Yaren Beast still let out a deafening roar of extreme pain, yet fierce and unyielding, the moment the incomparably violent energy was forcibly poured into its body!

The sound waves whipped up the flames, and scorching air currents swept in all directions.

That was no ordinary fire, but a "Melting Gold Fiend Fire" that combined pure earth vein fire and fierce metal spirit fire!

It penetrates everywhere, burrowing into every pore of the Yaren Beast, scorching every inch of flesh, pounding every bone, and scouring every meridian!

This kind of forging is not just high-temperature roasting, but also the sharp cutting of metal evil energy and the erosion and penetration of earth fire evil energy, the level of pain is far beyond imagination.

The Yaren Beast's dark red fur danced wildly amidst the towering pillar of fire.

Sometimes it turns black and curls up, and sometimes it regenerates rapidly under the nourishment of the surging golden spiritual energy, becoming more resilient and shimmering with a metallic luster.

The cycle repeats itself endlessly, like undergoing the most brutal yet most effective process of tempering and refining.

The pupils of the ferocious tiger in the Purgatory suddenly shrank to pinpoints.

Having been through it all, it could naturally understand the extreme pain that the Yaren Beast was currently enduring—a pain so intense that it could instantly shatter the soul and turn the body of an ordinary third-tier demon beast into ashes.

But what shocked it even more was that the figure at the center of the pillar of fire, despite trembling violently, maintained the same posture of stretching its neck towards the sky and crouching to gather strength.

He even actively activated the violent demonic power within his body.

Guide this "forging" power, which is capable of destroying everything, precisely flow to the blood vessels, bones, and joints throughout the body, especially to the old wounds and dark marks left by past battles!

The burning of flames and metal seemed to last for an unknown amount of time, as long as an eternity, yet also as short as a fleeting moment.

The roar of the Yaren Beast gradually changed.

The pure scream of pain transformed into a deeper, more suppressed growl, as if squeezed from the deepest part of the chest.

It contains not only pain, but also an unbridled ferocity and indomitable will that has been brewing to the extreme!

Its body seemed to shrink and solidify slightly in the raging flames, but the outline of every muscle became incredibly clear and smooth, and the lines were full of explosive power and beauty.

A layer of fine, mysterious, and seemingly naturally formed dark gold patterns began to emerge on the dark red surface, faintly forming a structure resembling some kind of armor.

Lin Che's expression suddenly changed: "Now!"

Without hesitation, he raised his hand and waved it. The three drops of precious dragon blood, which had been prepared and sealed in the ancient jade, transformed into three golden-red streaks, radiating a faint dragon's might.

Ignoring the raging molten gold fire that blocked its path, it precisely pierced the three vital points of the Yaren Beast at the center of the fire pillar: its brow, heart, and dantian!

"Awooo—!!!"

The moment the dragon blood entered its body, the roar of the Yaren Beast suddenly rose.

It became incredibly high-pitched and desolate, even strangely mixed with a trace of the power of a true dragon's roar that did not belong to it, as if it came from the ancient primordial world!

Its body suddenly swelled up in the pillar of fire.

The molten gold flames burning all over its body seemed to have met their nemesis. Instantly, they were suppressed by a more powerful, noble, and domineering golden-red light that burst forth from within, and then were frantically devoured and absorbed by it!

The already incredibly sharp claws grew another half foot, and in the cold light, fine, dark gold patterns resembling dragon scales faintly appeared. A touch of gold and red at the tip of the claw seemed to drip lava.

The bone blade on his right arm underwent a complete transformation, shedding its bone structure and turning into a dark golden, curved blade about three feet long with a perfect arc!

The blade is as thin as a cicada's wing, yet it flows with blood-red dragon-shaped patterns. With a gentle swing, the surrounding air emits a mournful sound as if it is being cut, leaving behind golden cracks that linger for a long time.

A terrifying aura, far more refined, concentrated, and ferocious than before, was emerging.

It was mixed with a faint but real dragon's might.

Like a peerless ferocious god who had been asleep for ten thousand years suddenly awakening, it erupted with a roar centered on the Yaren Beast, sweeping across the entire volcanic area!

The surrounding molten metal flames were extinguished by this aura, with most of them suddenly going out.

The piled-up ore hills seemed to have undergone thousands of years of weathering, losing all their luster and turning into a pile of ordinary gray-white stones.

The Hellfire Tiger involuntarily lowered its body, letting out a low growl as if issuing a warning, its eyes filled with shock and vigilance.

The sense of oppression emanating from the Yaren Beast at this moment is completely different!

The flames and the soaring golden-red light slowly subsided and calmed down.

Above the Earthly Fiend Golden Spirit Eye, a brand new figure, exuding a suffocating presence, stood proudly.

Its body shape is more proportionate and agile than before.

Its entire body is covered with a layer of dark gold, with a dense outer skin that looks as if it were forged from a hundred-times-refined divine gold and then overlaid with fine dragon scale patterns.

It appears to have a deep, understated luster, yet it exudes an indestructible texture.

Its claws slammed into the scorching rocks, which silently crumbled into dust.

The curved dragon blade on his right arm hung down naturally, its tip lightly touching the ground, leaving a deep, bottomless cut.

What's most intimidating are those vertical pupils, still blood-red, but now containing not only ferocity, but also the coldness, rationality, and arrogance of a top predator.

The spiritual pressure emanating from its body had clearly reached the level of a fourth-tier superior ferocious beast!

Yaren Beast, successfully advanced! Bloodline transformation, rank leap!

Perhaps, it should now be called—the Yaren Beast!

It slowly turned its head, its pair of scarlet, cold vertical pupils first looking at Lin Che in the distance.

The fierce and violent glint in his eyes quickly subsided, transforming into a deep sense of awe and gratitude.

It lowered its now even more majestic head and let out a low but clear hiss, carrying a sense of submission and closeness, towards Lin Che's direction.

Then, its gaze swept towards the Hellfire Tiger not far away, a familiar, eager, and fiery fighting spirit flashing in its eyes.

Sensing this gaze, the Hellfire Tiger stood up, shook its massive head, and responded with a powerful roar that showed no weakness. Its crimson-gold eyes also ignited with fighting spirit.

Yaren Beast has been undergoing bloodline advancement for a long time now, and he has been patiently waiting for it.

Lin Che looked at the powerful Yaren beast, which had successfully undergone a perilous transformation, and a look of satisfaction flashed across his eyes.

"The experimental plan is more than half successful."

Once the bloodline of the Yaren beast has fully stabilized and adapted to its new power, he can try using the power of the system to perform another targeted upgrade.

At that time, the speculation about whether dragon-type spirit beasts can transform into dragons by increasing the purity of their bloodline will be truly verified!
