In a perfect world, you start by relying on your own strength.

The Cave Heaven is both a realm of cultivation and a transcendent method of cultivation. Cultivators can use the Cave Heaven to absorb the essence of heaven and earth, comprehend the origin and profound meaning of Dao talismans, understand the order of the universe, replicate the creation of heaven and earth within themselves, and form their own small world. This is the way of the Cave Heaven.

The so-called "Cave Heaven Realm" refers to the creation of an ancient and immortal spatial passage within or outside the physical body, condensing a pure land, or even creating a complete world.

Shi Geng had long since grasped the mysteries of the cave heaven, and he had honed the Blood Moving Realm to its ultimate limit. All his breakthroughs came naturally.

"Boom—!"

A deafening roar shook the heavens and the earth, shattering thousands of mountains and causing countless peaks to resound in unison, its immense power resembling the collapse of the sky.

Countless runes manifested in the void, densely packed with flowing golden light, as if cast and sculpted from celestial gold, imprinting themselves on the void, instantly engulfing Shi Geng entirely in a sea of ​​dazzling runes.

Runes swirled around his body, penetrating through the pores of his skin and flesh. His previously surging blood and qi suddenly stagnated, then expanded dramatically, frantically squeezing and expanding into the void within his body.

Shi Geng could sense that a void space was being carved out of its boundaries little by little by runes, and strands of the essence of heaven and earth were flowing in from all directions, continuously pouring into that nascent land through the invisible channels constructed by the runes.

"The Cave Heaven Opens!"

The earth-shaking roar continued unabated. The spiritual spring from the ground gushed forth and shot into the sky. The clouds were pulled by an invisible suction force and swirled into a huge vortex in the high sky. The essence of the plants and trees within a thousand miles was all lifted into the air and transformed into countless fine streams of light that flowed into the runic light screen.

Shi Geng's bones and muscles crackled and popped as his physical body was being reshaped by the power born from the cave. His blood-moving body, which had already reached its limit, continued to shrink inward, while the void outside his body gradually expanded, slowly extending from a small square inch in size.

The rudiments of soil, spiritual veins, and gentle breezes quietly emerged in that grotto-heaven, forming a self-contained cycle of birth and death in the order of heaven and earth. Countless runes rose and fell and evolved on their own in the sky above the grotto-heaven's pure land, deducing the laws governing the operation of all things in the world.

As if drawn by the emergence of the grotto-heaven, the void stretched out in winding cracks, through which the faint light of stars from beyond the realm shone, reflecting off the runes.

Some of the runes broke free from the light barrier and landed, transforming into low-lying spiritual mountains and trickling streams. In a short while, a miniature world appeared out of thin air, centered on Shi Gen and within a radius of a hundred feet.

Shi Geng suddenly opened his eyes, and it seemed that there was a small world of the changing seasons hidden in his eyes. His aura changed from its usual peacefulness to a deep and vast one, as if the whole earth was rising and falling with his breath.

In the blink of an eye, the cave heaven was completely stabilized and formed. The cave heaven was connected with heaven and earth, and the essence of heaven and earth could be absorbed at will. The runes that imprinted the order of heaven and earth all returned to the depths of the cave heaven to lie dormant. At this point, Shi Geng officially broke through to the cave heaven realm.

Looking up, one can see a cave suspended above Shi Gen's head, its shape resembling an ancient, gray-brown volcano crater. Inside the cave, crimson energy surges and flows endlessly.

The grotto-heaven connects to the void of heaven and earth, continuously drawing in the essence of heaven and earth from the outside world. The essence of heaven and earth from the outside world merges and refines with one's own original qi and blood, forming a self-circulating cycle.

However, the transformation was far from over. Shi Geng's body trembled violently, and a continuous roar erupted from within him. A sky full of rosy light poured down, and auspicious rays surrounded him. The resounding sound rolled and rippled, causing the surrounding air to hum continuously.

The void beside him suddenly twisted and collapsed, and a gray-brown volcano solidified out of thin air, its crater outline lifelike, as if it had been created by nature.

Deep within the mountain pass, the vital energy surged and boiled, with silvery-white light flowing like molten lava, constantly rising and falling at the cave entrance.

The roar grew louder and louder as the second structure took shape, rooted in the void, its essence surging endlessly.

Before the strange phenomenon subsided, Shi Geng's physical body trembled even more violently, and the radiant light around him suddenly intensified several times, with auspicious colors like a waterfall of light covering the sky.

The void began to ripple and collapse, and the third and fourth grotto-heavens were successively opened up and revealed to the world. The four grotto-heavens hung in the void beside him, their openings spewing out the essence of heaven and earth.

The molten essence circulated and flowed within the four caves, and immense power surged from within, causing the ground beneath their feet to sink and crack. The booming sounds echoed for thousands of miles, and the essence of heaven and earth seemed to go mad as it rushed and converged on Shi Geng's body.

With all four grotto-heavens opening simultaneously, a massive amount of essence continuously nourished the flesh, blood, and internal organs, while the profound divine power accumulated in the Blood Transport Realm flowed throughout the body along the meridians of the grotto-heavens.

If any cultivator were to witness this scene or hear about it, it would surely cause a huge uproar, enough to shatter the preconceived notions of countless cultivators.

It should be understood that for ordinary cultivators who step into the Cave Heaven Realm, the limit is that they can directly open up one Cave Heaven. To open up more Cave Heavens, it is common to need to spend several years or even more than ten years to hone their skills. Those with shallow opportunities may even be stuck outside the threshold for life, only able to open up one Cave Heaven in their entire lives.

A rare and exceptionally talented individual in the world, when given the right opportunity, simultaneously opens two or three grotto-heavens upon breaking through to a higher realm. Such individuals are worthy of being hailed as prodigies by major clans and recorded in the sect's annals.

However, as soon as Shi Geng stepped into the Cave Heaven Realm, he opened four Cave Heavens in a row. The four Cave Heaven Volcanoes hung beside him, with their essence flowing endlessly.

Once this matter spreads, the entire lower realm will be in an uproar because of this news.

The four grotto-heavens took root in the void, and the surging essence circulated along the meridians of the body. The violent shock had just subsided slightly, and the strange phenomenon only paused for a moment before the divine power in Shi Geng's body surged violently once again.

His body suddenly radiated a burst of light, and the auspicious colors of the sky twisted into a thick pillar of light that shot straight into the clouds. The essence of heaven and earth around him seemed to be gathered by an invisible giant hand, turning into a raging torrent that poured into his body.

The void beside him twisted and cracked once more, and the fifth grotto-heaven slowly emerged from the nothingness, with the primordial essence of the new grotto-heaven continuously gushing out from the depths of nothingness.

Five grottoes floated on either side of the stone wall, simultaneously absorbing and releasing vital energy. The immense power intertwined, causing the ground beneath their feet to crack layer by layer like a spider web, and a thunderous roar echoed throughout the surrounding mountains.

As soon as the five grotto-heavens solidified and took shape, the immense divine power dormant within Shi Geng's body exploded once more. His physical body trembled incessantly, and his entire body radiated a blazing light like the sun hanging in the sky, while auspicious colors surged across the heavens like a sea of ​​clouds.

Dark folds appeared continuously in the void. The sixth and seventh grotto-heavens broke free from the shackles of nothingness. Silver essence surged like boiling broth inside the grotto-heavens, and the surging source flowed into the limbs and bones through the meridians of the flesh.

The roar echoed through the mountains and valleys, and the essence of heaven and earth surged in from all directions, turning into a visible torrent that enveloped the rocks.

The eighth grotto-heaven took shape shortly afterward, suspended in mid-air and arranged in a staggered pattern. Before the disturbances in heaven and earth could subside, the ninth grotto-heaven broke through the void and slowly landed. Nine volcanoes surrounded it, and the nine cave entrances spewed out essence at the same time. The nine streams of essence flowed and intertwined in the air, weaving a vast field of light.

With all nine grottoes open, immense power washed over his body through the grotto passages. The vast amount of divine power that had accumulated in the Blood Transformation Realm was absorbed and transformed by the grottoes, and Shi Geng's aura steadily increased.
