I established the Eternal Immortal Clan by taming beasts.

It's not just the Fiery Tiger of Purgatory.

The Azure Profound Realm Spirit also grasped that feeling.

Unlike the Burning Sky Sacred Sparrow, the Azure Profound Realm Spirit is not a fire-attribute spirit beast. It does not possess the flamboyant and domineering power of flames within its body, and it is not even considered a normal spirit beast.

Kong Yinsang is the core of the Qingxuan Secret Realm, and he is more like the realm spirit of the secret realm.

It is a darling of the laws of space, and has been inseparable from the word "space" since its birth.

It can travel through the void, sense the folds of space, and capture the most subtle fluctuations in the universe that ordinary people cannot perceive.

That's why all the spirit beasts could break through in the secret realm, but he couldn't.

Because among the laws governing the world that constitute the secret realm, only the law of space is incomplete or inadequate.

Therefore, its breakthrough point must be the outside world.

In the end, Lin Che chose the depths of the Black Tooth Swamp, within the ruins of the Thousand Water Beast Taming Sect.

The poisonous miasma over there is decreasing year by year, and the environment is gradually improving under the purification of the White Bone Cleansing Lotus.

When Lin Che first arrived, the place was shrouded in poisonous miasma, so dark that you couldn't see your hand in front of your face and even breathing was difficult.

Now, only the spiritual veins have not been completely purified.

So the Lin family began to gradually renovate the ruins.

The ruins were cleared away, the collapsed stone steps were repaired, and the buildings eroded by time were brought back to life.

The most important formations are also being perfected, including a third-tier high-grade formation that Master Qin has recreated: the Nine Heavens Cloud Realm Formation.

At this moment, the power of the Nine Heavens Cloud Realm Array was turned up to the maximum to prevent it from being detected by the outside world.

The breakthrough of the Hellfire Tiger outside the Lin family territory was also a cover for the breakthrough of the Azure Profound Realm Spirit.

Draw everyone's attention to Shattered Star Lake, and focus all the spies' attention on the Golden Core Spirit Beast, then let the Azure Profound Realm Spirit complete its Core Formation in the Black Tooth Swamp.

Lin Che stood deep within the Black Tooth Swamp, at the highest point of the Thousand Water Beast Taming Sect ruins.

He withdrew his gaze from his surroundings and looked at the deep pool below the ruins.

The original testing ground has been completely demolished, but the pool of water has been preserved.

The pool water was still dark and murky, its depth indiscernible, but compared to many years ago, it could no longer be called a poisonous pool.

The fourth-tier White Bone Pure Lotus still grows in the center of the pool, its petals as white as jade, emitting a soft glow in the dim environment.

Over the years, it has purified most of the poisonous energy in this area. The pool water no longer emits a pungent smell as before, and has even begun to exude a spiritual aura.

The Azure Profound Realm Spirit hovered above the pool, its entire body enveloped in a layer of dark blue light.

The light was very faint, like starlight in the night sky, almost invisible in this dim environment.

Its body glowed faintly.

It wasn't a dazzling light, but a soft, elegant halo, like moonlight filtering through a thin mist onto the water's surface.

The light flickered, like breathing, and with each flash, a faint spatial fluctuation spread outwards.

Lin Che looked at him quietly, without urging him.

He knew that the breakthrough of the Azure Profound Realm Spirit did not require the help of external forces.

The Azure Profound Realm Spirit slowly closed its eyes.

Its consciousness sank into a strange state.

It's not cultivation, not meditation, but a state of communion with heaven and earth.

It felt that it was no longer an independent individual, but had become a part of this world, a part of the air, a part of the wind, a part of those invisible and intangible spatial patterns.

It could sense those patterns before, but could only glide around the edges, like a dragonfly skimming the water.

But at this moment, it felt as if it could "dive" into the depths of those patterns and touch something more primal.

That is the foundation of the laws of space.

It is not of a particular secret realm, nor of a particular space, but rather the most fundamental, omnipresent, and fundamental spatial law that sustains the existence of all things in this world.

It used to be able to glide on those textured surfaces, like a dragonfly skimming the water.

But at this moment, it felt as if it could "dive" into the depths of those patterns and touch something more primal.

The demonic power within his body began to change.

It is not a rushing, turbulent surge, but a slow, rhythmic movement, like the ebb and flow of the tide.

That force spreads outward from its core and then contracts inward, rising and falling, becoming slower and heavier.

Each contraction presses a wisp of spatial power into its nascent golden core.

Each expansion expels impurities from the Golden Elixir from the body.

Strange lights and shadows began to appear in the sky above the canyon.

It wasn't lightning, nor fire, but rather faint folds in space, like crumpling and unfolding a flat piece of paper, leaving indelible marks.

Those wrinkles were clearly visible under Lin Che's "Wind Eye Break" gaze, but even if an ordinary cultivator passed by, he would only feel that the sunlight was a little dazzling, and would not notice anything unusual.

They exist for a very short time, fleeting like ripples on the water, disappearing in an instant.

The light surrounding the Azure Profound Realm Spirit changed from a dark blue to a deeper, dark blue-black, like the night sky.

The light no longer radiated outwards, but instead converged inwards, condensing into an invisible "core" within its body.

That was no ordinary demon core; it was more like a tiny spatial node compressed to the extreme, connecting it more closely with the spatial laws of heaven and earth.

It can no longer only perceive those patterns, but can truly "touch" them, and even "guide" them to some extent.

The whole process lasted a full day and night.

Lin Che stood at the highest point of the ruins for a day and a night without closing his eyes or leaving.

He observed the changes in the light emanating from the Azure Profound Realm Spirit and sensed the intensity of the fluctuations in the surrounding space, not missing a single detail.

The next morning, as the first rays of sunlight shone on the ruins, the Azure Profound Realm Spirit opened its eyes.

The silvery-white halo in those pupils had dissipated, replaced by a more restrained, soft light, like moonlight shining on snow.

Its shape remained unchanged, and its aura was not as sharp as other Golden Core stage spirit beasts, but Lin Che knew that it was different now.

"How is it?"

The Azure Profound Realm Spirit slowly floated to his side, its blue-black light receding.

Its voice resonated in Lin Che's heart, carrying a rare sense of ease and an indescribable sense of satisfaction.

"Not bad." There was no pride or arrogance in his voice, only a calm and composed demeanor, as if he had accomplished something important.

"The outside world is much wider and more complex than the secret realm. In the future, I can go to even farther places."

Lin Che nodded in satisfaction.

During the Foundation Establishment stage, the maximum distance that the Azure Profound Realm Spirit can teleport is 1,200 li.

Twelve hundred li is enough to cover most of Chuyang City and Burning Bone Pass, but it won't be able to go any further.

Now that he has reached the Golden Core stage, that distance has increased again.

With this, the Lin family now possessed its fourth Golden Core stage spirit beast.

……

Time flies, and eight years have passed in the blink of an eye.
