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

Relying on the profound foundation accumulated during his Blood Transformation Realm period, coupled with the terrifying foundation he had honed day and night during this time, Shi Geng, after accumulating strength, opened up nine cave heavens in one go.

Nine grotto-heavens hung in the air, their entrances surging with primordial energy like magma, their spiritual light spreading for thousands of miles, frantically absorbing the essence of heaven and earth, while the surging divine power within was slowly drawn back into the various grotto-heavens.

Nine is the ultimate number in the universe, which is already the limit of the Cave Heaven realm. To open a tenth Cave Heaven would be to defy the universe and forcibly break through the limits, making it almost impossible.

Even Liu Shen, who was used to seeing geniuses and prodigies, couldn't help but take notice. To be able to open all nine caves at the same time upon entering the cave world was a unique achievement, even in that extremely glorious era. Moreover, it seemed that this little guy still had plenty of energy left.

The nine grotto-heavens resonated with each other, continuously drawing upon the essence of heaven and earth to nourish his flesh and bones. Under the infusion of this massive amount of essence, Shi Geng's physical body and divine power rapidly transformed, and his aura grew stronger every moment, even showing faint signs of breaking through to the next realm.

He had already grasped the profound meaning of cultivation in the Spirit Transformation Realm. With just a thought, he could break through the shackles and step into the next realm. However, Shi Geng forcibly suppressed the urge to advance in this way.

To outsiders, the Nine Caves Realm is the pinnacle, but for him, the path to the Cave Heaven Realm is far from over. He still has ample resources buried deep within him, and he can go even further in this realm. The Nine Caves Realm is the limit for those geniuses, but it is not his limit.

The nine suspended volcanic caves trembled slowly, and the essence gushing from the mountain mouths suddenly became condensed and restrained, no longer leaking out recklessly, but flowing back into the body's meridians.

Shi Geng focused his mind and used the boundless divine power accumulated from his Blood Transformation Realm as fuel to slowly polish the nine cave heavens that had already taken shape. The surrounding rosy light slowly receded into his body, and the roar that shook the mountains and fields gradually subsided. Only deep within the nine cave heavens, a magnificent power was waiting to be unleashed.

Shi Geng sat cross-legged under the willow tree for ten days and ten nights.

The difficulty of opening the tenth grotto-heaven far exceeded his previous expectations. Nine is the ultimate number and is a cultivation barrier secretly set by heaven and earth. To create another grotto-heaven outside the ultimate number is almost like going against the heavens.

"The Tenth Grotto-Heaven opens!"

Suddenly, Shi Geng's eyes flashed with brilliant golden light, and his shout shook the clouds in the sky, causing them to collapse. The immense divine power that had been dormant within him for so long exploded in an instant.

The nine grotto-heavens, which had long been perfected, roared and vibrated in unison. The primordial essence surging from the entrance of the grottoes rose into the air and gathered, transforming into a vast river of light that poured into the void rift.

As if sensing something, the wind and clouds in the sky swirled back, faintly producing a muffled, oppressive roar. The surrounding energy of heaven and earth became chaotic and stagnant, as if resisting this pioneering act that defied the established order of the world.

The void was torn apart layer by layer by the immense force, and a brand new mountain outline slowly emerged from the nothingness. The tenth grotto-heaven broke through the natural shackles of the number nine and began to condense little by little.

Ten caves are scattered around the stone, and the ten cave entrances simultaneously spew out silver light. The primordial essence is connected end to end, forming a perfect closed loop in mid-air.

The profound foundation accumulated by the Blood-Moving Realm continuously poured into the new cave heaven, and the originally stagnant essence of heaven and earth surged wildly again. The mountains, forests, and vegetation within a ten-kilometer radius were nourished by the essence and sprouted and grew wildly.

The tenth grotto-heaven gradually solidified from its initial vague outline, becoming more and more real. The primordial essence within the grotto-heaven surged continuously, communicating with the celestial mechanisms of the other nine grotto-heavens.

Opening up the ten grotto heavens is tantamount to seizing the opportunity of creation from the hands of heaven and earth, defying the heavens and breaking the predetermined fate.

In the world, any cultivator who can open four cave heavens is considered to have achieved the perfect Cave Heaven Realm and can begin to break through to the Spirit Transformation Realm.

Most geniuses are content with reaching the fifth or sixth cave, but no one has ever broken through the norm like Shi Geng, advancing all the way. He opened up the ninth cave with a single breakthrough, and now he has opened up the tenth cave, which surpasses the limits of heaven and earth.

Rumbling sounds rose and fell, and the tenth grotto-heaven completely solidified and took shape, like a gray-brown mountain rooted in the void. Wisps of ethereal immortal energy rose and drifted from the gaps in the grotto-heaven, exuding a faint Daoist aura.

The tenth grotto-heaven is far larger than the other nine, resembling a gray-brown mountain that stands majestically atop the Stone Heaven.

The remaining nine grotto-heavens were much smaller in comparison, scattered and suspended around the stone wall, like subordinates under the command of the tenth grotto-heaven.

The tenth grotto-heaven continuously emanates its essence, with strands of essence connecting the nine grottoes downwards, seemingly forming a natural order that commands the entire grotto-heaven system from above. The surging silver essence within the other nine grotto-heavens actively converges under this pull, all being controlled by the main grotto above.

A wisp of the essence of heaven and earth overflowed from the tenth grotto, its vast power permeating the surrounding world. The energy of the ten grottoes resonated in unison, echoing each other. The primordial essence and the misty immortal energy blended together, swirling and flowing around him, forming a small world of their own.

A massive amount of the essence of heaven and earth was drawn into the cave and continuously poured into his body. Under the nourishment of the cave, Shi Geng's flesh, organs, and bones were constantly transforming, and his foundation was already far more solid than that of his contemporaries.

"Phew, we've finally opened it up. Opening up the tenth cave is no ordinary difficulty."

Shi Gen slowly exhaled a long, turbid breath. The difficulty of opening up the tenth cave heaven far exceeded the sum of the previous nine cave heavens.

He opened up the nine grotto heavens in just half a month, but the tenth grotto heaven, which surpassed the limits of heaven and earth, took him two whole months to open.

Even though he had accumulated unparalleled divine power in the Blood Transformation Realm and had the resources he had acquired during this period, making him well-prepared, he still almost failed.

His accumulated foundation was completely depleted. During the process of opening up, he even suffered backlash several times, his physical body cracked and his origin collapsed, teetering on the edge of life and death, and several times on the verge of his Dao foundation collapsing.

Fortunately, with his extraordinary willpower, he endured these life-and-death trials and tribulations, creating a miracle from the impossible, breaking the shackles of the number nine, and allowing the supreme grotto-heaven that governs the nine grotto-heavens above his head to take shape.

"Now, we can begin to explore the inner world."

A glint flashed in Shi Geng's eyes. Opening up the tenth grotto-heaven was just the beginning; this breakthrough was not yet complete.

Shi Geng turned his head to look at Liu Shen and said in a deep voice, "Liu Shen, I would like to trouble you to lend a helping hand at this critical moment."

"Just go for it and break through."

The voice of the Willow God came slowly through the divine thought. He was also very curious about what this little guy wanted to do. Could it be that the Ten Caves Heaven could not satisfy his ambition?

"Thank you, Goddess Liu."

Shi Geng bowed to the Willow Goddess and received her personal guarantee, which instantly increased his confidence in opening up the inner world.
