I established the Eternal Immortal Clan by taming beasts.

Wisps of smoke curled upwards, and the calming fragrance of the wood lingered slowly within the cave, adding a touch of solemnity to this crucial moment.

Lin Che sat cross-legged on the central futon, his back straight as a pine tree.

His eyes were slightly closed, his breathing was deep and long, and he was adjusting himself to an unprecedented peak.

Along the way, he gathered knowledge about foundation building.

I understand that the most important thing in foundation building is essence, energy, and spirit.

All three are indispensable, because the essence of Foundation Building is a complete leap in life level, a comprehensive "evolution," which cannot be achieved by simply accumulating spiritual power.

The Qi within is spiritual power, which is fundamental to cultivators.

One must cultivate Qi to perfection, with the Dantian Qi vortex full and surging, and the spiritual power overflowing, in order to generate sufficient "pressure" and "density" to complete the qualitative change from gaseous to liquid state under the guidance of the cultivation method, transforming spiritual energy into true essence.

This is the foundation of energy, just like the bricks, stones, and earth needed to build a tall building; it is the most important.

With spiritual power far exceeding that of ordinary cultivation techniques cultivated through a Heaven-rank technique, coupled with the Holy Spirit Root making the spiritual power absorbed by him extremely pure, this aspect of refinement will absolutely not be a problem.

God refers to the spirit and soul.

During the foundation-building process, spiritual energy undergoes a qualitative change, the physical body transforms, and energy surges violently like a river bursting its banks.

Without a highly concentrated, resilient, and powerful divine consciousness as a "helmsman" to provide precise guidance, one may fail to establish a foundation at best, or even have their meridians shattered and their path to enlightenment severed at worst.

His "Ten Thousand Beasts Paying Homage to the Ancestor" is a Heaven-rank cultivation technique, mainly designed to make the master's soul incredibly powerful, thereby enabling him to control all spirits. It inherently emphasizes refining the spirit, making his soul strength far surpass that of others of the same rank, allowing him to control spiritual power with ease.

However, it falls slightly short in terms of refinement.

During the Foundation Establishment process, gaseous spiritual energy is compressed into liquid true essence, and the internal pressure generated during this process is terrifying.

If the physical body is not strong enough, the meridians and dantian will be like a fragile, narrow path suddenly hit by a flash flood, with only one way out: collapse.

This is why cultivators over sixty years old, whose vital energy and blood begin to decline, have a significantly lower success rate in Foundation Establishment.

It takes an ordinary person with a mid-grade spiritual root thirty or forty years to reach the perfection of Qi Refining. During this time, they also need to spend time improving their cultivation and earning resources. Where would they find the time to cultivate their physical body?

But Lin Che is different! He possesses the Holy Spirit Root, so his cultivation speed is already astonishing. Furthermore, he has the spiritual power of his natal spirit beast to nourish him, giving him the energy to pursue the most perfect Dao foundation.

To achieve immortality, one's foundation must be extremely stable.

To this end, he painstakingly collected various body-refining techniques and used the system to help them advance their ranks, eventually choosing the "Nine-Refined Golden Body".

This seemingly simple and unadorned spiritual-level cultivation technique directly targets the essence of the physical body.

This technique does not pursue flashy supernatural powers or induce special physical constitutions. Instead, it uses nine extreme "forging" processes to sculpt the physical body into a flawless form, like refined gold that has undergone countless hammerings.

After ten years of arduous practice, he pushed this technique to the ninth level, the "no leakage" realm. The pain he endured during this time, including the tearing of tendons and bones and the steaming of qi and blood, was beyond description.

Without the unwavering will honed in his early years as a demonic cultivator, and his most instinctive thirst for power, he might not have been able to persevere.

Otherwise, I wouldn't have this flawless body with its dragon-like energy and inner radiance.

Another advantage of this body-refining technique is that it will not cause any conflicts when switching to other advanced body-refining techniques.

This allows Lin Che to continue cultivating a high-level body-refining secret technique after he reaches the Foundation Establishment stage!

……

With a slight thought, a flash of white light appeared beside him, and the Heavenly Sacred Sparrow quietly appeared, gracefully landing on the futon beside him.

Now, she is exceptionally beautiful, with a powerful physique like an eagle, a wingspan of nearly four meters, and a streamlined body covered with crimson jade-like feathers that have a warm luster and a faint golden glow.

The natural heat emanating from her body caused the air to distort slightly, and the pure and intense spiritual pressure far exceeded that of an ordinary Qi Refining Perfection cultivator.

His golden eyes, still haughty as ever, now looked at Lin Che with barely concealed excitement: "Is it starting?"

She had already reached the peak of Qi Refining, but due to the bond of her natal spirit contract, she and Lin Che cultivated together and grew together, which is why she was stuck at this level.

Otherwise, with his extraordinary bloodline and Lin Che's generous support, he would have already reached the Foundation Establishment stage.

"Yes, today." Lin Che gently stroked her shimmering feathers, feeling the close connection between their spiritual energy fluctuations. He took a deep breath, his eyes sharp and resolute: "Let's begin!"

"Alright!" The Burning Heaven Sacred Sparrow nodded solemnly, suppressing the excitement in his heart, and quickly calmed his mind and adjusted his state.

A man and a sparrow sat facing each other.

The two auras began to slowly merge and resonate, gradually becoming one.

This is the mystery of the natal spiritual contract—cultivating life and spirit together to reach the peak!

Ordinary cultivators rely on Foundation Establishment Pills to forcibly expand their meridians with their potent medicinal power, causing a surge of spiritual energy to impact their dantian.

When a cultivator who practices the Myriad Beasts Paying Homage to the Ancestor Technique possesses a high-quality natal spirit beast, as long as the cultivator takes the first step to initiate Foundation Establishment and removes the restriction on realm, the natal spirit beast can begin Foundation Establishment as well.

By utilizing the abundant spiritual energy fed back by the spirit beast during its foundation-building process, one can also draw upon the spiritual power within one's own dantian to form a tide and complete a breakthrough.

It can be said that as long as a cultivator has mastered the Body Refinement Technique and cultivated the Myriad Beasts Paying Homage to the Ancestor Technique, even if they have a low-grade spiritual root, they may be able to establish their foundation without using a Foundation Establishment Pill!

Two days passed quietly, and the energy within the cave had reached its peak. The spiritual power of humans and birds blended seamlessly, becoming indistinguishable from one another.

Foundation building, officially begins!

Lin Che focused his mind on his dantian and circulated his cultivation technique with all his might. The originally steadily rotating spiritual energy vortex was suddenly activated and began to compress wildly inward!

The balance was instantly shattered, and the spiritual energy became violent and chaotic, like a swirling vortex.

Almost at the same moment, the Burning Sky Sacred Sparrow clearly sensed that the invisible barrier blocking her way had shaken violently due to Lin Che's initial impact, and a crack had appeared!

Without hesitation, she activated her bloodline with her thoughts, and the crimson-gold Phoenix Blood True Fire instantly enveloped her dantian. Instead of compressing it roughly, she began to refine and purify the gaseous spiritual energy in a way that was more in line with the origin of her bloodline, causing it to actively transform into a higher level of liquid true essence!

"boom--!"

As if a volcano that had been dormant for ten thousand years had finally erupted, a pure, explosive, yet sacred fire-attribute primordial spiritual power surged into Lin Che's dantian through that natal spiritual contract!

This power far surpasses the effects of ordinary spiritual energy tides. As soon as it entered, it instantly transformed into a sweeping crimson-gold lotus storm, completely devouring, shattering, and assimilating the already chaotic spiritual energy vortex within Lin Che's dantian, turning it into part of the storm!

"Hmph!" Intense pain shot through his limbs and bones, his meridians bulged as if they were about to burst.

Lin Che's forehead instantly broke out in fine beads of sweat, and his body trembled slightly, but he clenched his teeth and kept his mind clear.

He fully activated the Myriad Beasts Paying Homage to the Ancestor Technique, using his extraordinary divine sense as a rein to forcibly restrain and organize this torrent of destruction and rebirth, compressing it little by little into a massive ball of spiritual energy that was spinning wildly and struggling violently in the center of his dantian!

The divine sense was like an invisible giant hand, continuously pouring in and constantly increasing pressure!

The color of the gas cloud deepened, gradually transforming from a gaseous state into a dense, viscous mist, like an unyielding spiritual liquid. Its internal energy surged, emitting a deep rumble.

Compression! More compression! Divine consciousness is nearly exhausted!

At the very center of that extremely thick cloud of spiritual liquid, a dazzling golden light, like the rising sun, suddenly burst forth!

"Tick-tock".

Like sweet dew falling into a jade plate, or like the first sound of the universe at the beginning of creation, it is crisp and contains boundless vitality.

A drop of perfectly round, flawless liquid true essence, as brilliant as pure gold and containing immense power and life force, quietly condensed at the very center of the cloud and dripped into the bottom of the dantian.

Then came the second drop, the third drop... the tenth drop, the hundredth drop...

As if it had triggered a resonance between heaven and earth, a chain reaction suddenly erupted, and the entire cloud of spiritual mist completely collapsed, transforming into a refreshing "True Essence Rain"!

Countless liquid true essences fell densely like raindrops, converging and merging, eventually forming a small but shimmering pool of liquid true essences at the bottom of Lin Che's dantian, radiating a vast aura and boundless vitality!

The moment the first drop of natal essence was born, an unprecedentedly powerful sense of strength, like a warm current or an electric current, instantly swept through the entire body!

Under the influence of purer and more vibrant liquid true essence, the meridians are ruthlessly widened and strengthened, becoming far more resilient than before.

The internal organs are deeply nourished by this pure energy, impurities are eliminated, and they radiate even more powerful vitality.

Bone density increases dramatically, revealing a jade-like luster; the body's blood and qi surge like the Yangtze River, roaring and vigorous, and vitality is as strong as fire.

His divine sense surged wildly at an unprecedented speed, expanding his perception range several times over. With the slightest thought, the tracks of insects crawling in the cracks of rocks outside the cave, and even the subtle flow of spiritual energy in the air, were clearly reflected in his "mind," revealing his keen insight.

Foundation laid, success achieved!

Almost at the same instant that Lin Che successfully established his foundation and completed the leap in his life level, a scorching, noble, and powerful spiritual pressure suddenly spread out beside him, scorching the air in the cave and slightly distorting it, making the fragrance of the calming wood seem even stronger.

The Heavenly Sacred Sparrow raised its long neck and let out a clear, melodious chirp that pierced the soul.

Her crimson-gold wings shimmered with light, as if she were draped in a sacred robe of flames, and her molten-gold eyes shone with divine brilliance, exuding majesty.

The moment Lin Che successfully established his foundation and broke through the shackles of their shared realm, she naturally and smoothly entered the Foundation Establishment realm as well!
