I gain ten years' worth of cultivation every day, and even geniuses will only see my doorstep!

This time, the number of demons is not only greater, but their strength is also significantly stronger!

Among the surging alien demons, the proportion of elite species has greatly increased, and even several general-level alien demons with auras reaching the peak of the Nascent Soul stage have appeared!

They stormed the city walls with relentless ferocity, even causing the once-solid "Earthfire Melting Gold Array" of Lava City to groan under the strain.

"It's a horde of demonic creatures!" an experienced cultivator exclaimed. "Every so often, the demonic creatures deep within the battlefield erupt in revolt, creating hordes that sweep across the land! Many small cities have been destroyed by these hordes!"

The pressure on the defending cultivators increased sharply. Even with Qin Yuan in charge, their killing efficiency was astonishing, but the alien demons seemed endless and could not be killed off.

Qin Yuan stood on the city wall, clearing out large groups of alien demons while extending his divine sense as far as possible into the depths of the battlefield.

At the very edge of his divine sense's perception, he detected an extremely violent, chaotic, and destructive energy fluctuation that was spreading continuously from the deepest part of the battlefield, like ripples affecting the entire battlefield and driving the alien demons into madness.

"This energy..." Qin Yuan's heart stirred slightly, and the mental cultivation method of the "Nine Deaths Nascent Soul Technique" started to operate on its own, actually generating a slight... desire for this violent energy?

His eyes lit up. Could it be that this violent energy, which emanated from the depths of the battlefield and triggered the demonic frenzy, could also be used for Nascent Soul tempering?

The Nine Deaths Nascent Soul Technique emphasizes the tempering of life and death, requiring extreme energy to hone the nascent soul. Earth Core Flame is one such energy. This violent battlefield energy, full of destruction and chaos, may also be a kind of "extreme".

With this in mind, Qin Yuan no longer hesitated. He instructed Chu Wuyue, Wen Ruohai, and the others, "I will go out of the city to scout; you all hold the city."

Before anyone could respond, he transformed into a streak of dark golden light, passing straight through the defensive light barrier and plunging into the boundless demonic tide outside the city.

Wherever it passed, the demons exploded, carving a path through the demonic tide as it sped toward the source of the energy fluctuations, deep into the battlefield.

The deeper they went, the stronger the demons became, and the clearer their violent energy became. A chilling aura of destruction permeated the air, the earth cracked, and even space itself seemed to distort.

Finally, Qin Yuan arrived at the edge of a massive circular rift valley. Deep within the rift, dark red magma churned, but even more striking was the central beam of energy—thick, pitch-black yet constantly flashing with crimson and ghastly green light—soaring into the sky!

Around the pillar of light, space continuously collapsed and repaired, emitting a sickening buzzing sound. The violent energy that had triggered the demonic surge was emanating continuously from this pillar of light!

"Such pure and violent destructive energy!" Qin Yuan felt a stinging sensation on his skin, but instead of being surprised, he was delighted.

This energy level is extremely high and highly unstable, full of destructive power, which perfectly matches the extreme and dangerous characteristics required for the tempering of the "Nine Deaths Nascent Soul Technique".

He sat cross-legged on a huge black rock at the edge of the rift valley, circulating the "Nine Deaths Nascent Soul Technique" while simultaneously activating the system to assist in deduction.

[A high concentration of mixed and violent energy of 'Void Annihilation Energy' and 'Abyssal Demonic Energy' has been detected... Energy properties: extremely unstable, highly destructive, and extremely corrosive... Direct absorption and tempering has a success rate of less than 5%, and a Nascent Soul annihilation rate of 99.9%.]

[Based on the key principles of the fourth stage, "Void Refinement," and the fifth stage, "Demon Tribulation Refinement," of the *Nine Deaths Nascent Soul Technique*, combined with the host's current third-stage Nascent Soul strength and the characteristics of the *Nine Revolutions Profound Origin Technique*'s original spiritual power, an optimized absorption and transformation scheme has been deduced... Constructing a "Yin-Yang Grinding Mill" spiritual power structure, with the original spiritual power of the *Nine Revolutions Profound Origin Technique* as the Yang side and the tempering power of the *Nine Deaths Nascent Soul Technique* as the Yin side, grinding, separating, and purifying the violent energy, extracting "Void Essence" and "Demon Tribulation Qi" for tempering... Optimized success rate: 68%, Nascent Soul damage rate: 35%. Execute?]

"Execute! Convert 10,000 energy points to enhance the Enlightenment and Protection states!" Qin Yuan decisively gave the order. With his cultivation level improved, the system's functions seemed to have become even stronger.

[Energy Points -10000. Current Energy Points: 33760. Enlightenment and Protection status activated. 'Yin-Yang Grinding Wheel' under construction...]

Within Qin Yuan's dantian, beneath the dark golden third-stage nascent soul, a strange, half-gold and half-black millstone phantom, slowly rotating, gradually took shape.

At the same time, he relaxed his mind and body, actively drawing upon the violent energy emanating from the towering pillar of light in the center of the rift valley.

"boom--!!!"

A torrent of violent energy, ten times more intense than the earth's core flames, instantly surged into Qin Yuan's body!

Wherever it passed, the meridians were in excruciating pain, as if they were being torn apart inch by inch!

But the "Yin-Yang Millstone" started operating in time, with gold and black light intertwining, drawing the destructive energy torrent into the center of the millstone, like a stone mill grinding beans, producing a dull rumble.

The violent energy was forcibly separated under the grinding action of the millstone.

The pitch-black "Void Annihilation Energy" and the crimson-green "Abyssal Demonic Energy" were extracted and then purified and transformed by the profound power of the millstone, becoming strands of pure "Void Essence" and "Calamity Demonic Energy," which, like trickles of water, slowly flowed into the dark golden nascent soul above.

The nascent soul trembled violently!

The fourth transformation, "Void Refinement," begins! The essence of the void is integrated, and the nascent soul is as if thrown into the boundless void, enduring the terrifying tempering of space tearing, squeezing, and folding. Its form shrinks again, and its color changes to a deeper dark gold, with faint silver starlight flickering.

Immediately following, the fifth transformation, "Demon Tribulation Refinement," arrived! Enveloped in demonic energy, the nascent soul was as if it had fallen into a demonic tribulation, enduring the painful tempering of heart demons corroding the bones and karmic fire burning the body. Faint, dark red patterns, like ancient demonic runes, appeared on the dark golden surface of the nascent soul, and its aura became increasingly ancient, profound, and unpredictable.

The pain far exceeded any previous tempering! Fine bloodstains appeared on Qin Yuan's body surface, but were instantly repaired by his powerful self-healing ability.

He focused intently on his spiritual platform, and in a state of enlightenment, precisely controlled the flow and rhythm of every bit of energy.

Time passed amidst extreme pain and transformation.

After an unknown amount of time, the energy pillar in the center of the rift seemed to dim slightly.

Within Qin Yuan's body, the illusory image of the "Yin-Yang Grinding Wheel" slowly dissipated. In his dantian, the dark golden nascent soul was no longer shrinking; instead, it had returned to its original size, but its entire body was as if forged from dark golden divine iron, incredibly solid, with its radiance restrained.

On the nascent soul's brow, besides the extremely faint golden-red flame pattern, there was also a silver starlight and a dark red demonic pattern, the three of which faintly formed a mysterious triangular pattern.

Fifth-stage Nascent Soul, accomplished!

Peak of the Nascent Soul Realm! Half-step into the Divine Transformation Realm!

Qin Yuan opened his eyes, his pupils seemingly shimmering with dark golden light, sparking electricity in the void. The surrounding violent energy was forced back several feet by this invisible pressure.

He slowly rose, feeling the terrifying power surging like the sea and condensed like steel within his body, as well as the indestructible and profound texture of the Nascent Soul containing the mysteries of the void and the demonic tribulation.

Although he is still in the Nascent Soul stage, his true combat strength is probably enough to directly match or even suppress ordinary early-stage Nascent Soul cultivators!

He looked up at the still dark red sky and the faint outline of the lava city in the distance.

"It's time to go back." Qin Yuan took a step forward, his figure already appearing a hundred feet away, his speed several times faster than when he came, disappearing into the horizon in the blink of an eye. Behind him, the raging energy rift continued to silently spew out destructive radiance.
