My transformation into a beautiful girl started with a hemorrhage.

Inspired by the Guiming Battle Technique, they conceived a wild idea: these warriors would unite to wage a battle against fate that would span a thousand years.

This is the Nine Heavens Capital Yin Demon Formation.

This grand formation uses the Valley of Burial Gods as its core and the giant mountain range occupied by the eight major sects and the Heavenly Dao Child as its nine major array tracks, covering the entire continent.

The entire project took a thousand years and consumed countless human, material, and financial resources.

The function of the Nine Heavens Capital Yin Demon Array is to forcibly intercept the souls of people after death, which should dissipate and return to the universe, and enter the array to grind these souls and release their true energy to nourish heaven and earth.

However, they failed.

The soul is formless and intangible; as a higher-dimensional being, how could it be so easily captured?

The Nine Heavens Capital Yin Demon Array can only capture some remnants of the soul when it dissipates.

Even after capturing a soul, utilizing its energy is incredibly difficult; the entire Nine Heavens Yin Demon Array's utilization rate of the soul is actually lower than that of the Returning to the Underworld Battle Technique.

Ultimately, the Nine Heavens Capital Yin Demon Array only slowed down the demise of the Qi in this world.

With their last hope extinguished, warriors throughout the ancient era gradually stopped mentioning the hopeless future of this world and focused only on the present.

No one bothered with the Nine Heavens Capital Yin Demon Formation anymore.

And so, this forgotten, monumental project silently...operated for a hundred thousand years, still fulfilling its mission, continuously capturing the remnants of souls after death and transforming them into true energy, releasing it through the nine mountain ranges...

Up to now.

As time passed and geological changes occurred, a crack appeared in the 10,000-meter-thick Burial Valley that covered the Nine Heavens Capital Yin Demon Array. It was not until Xia Yuyu accidentally discovered it that this monumental project was able to emerge from the corner of history.

Although people's bodies have undergone tremendous changes due to environmental shifts, making them unable to adapt to an environment filled with true qi, true qi is not a rare treasure but rather a potent poison. Its immense activity makes it the world's strongest corrosive agent.

However, Xia Yuyu discovered another way to achieve the Innate Realm: let the Grandmaster directly enter this environment full of true energy and use his physical body to resist the corrosion.

Once you overcome the resistance and your body adapts to the true qi, then the true qi will circulate within your body, and those who can utilize the true qi will be innate martial artists.

However, if they fail to survive, their remains will be lost forever.

To survive this process, countless lives were sacrificed throughout the Xia Dynasty, leading to the conclusion that only Grandmasters had a 3% chance of success, while those below the Grandmaster level were doomed to die.

at this time.

Hui slowly descended a few hundred meters above the center of the Burial Valley, marveling at the ingenuity of the ancients while simultaneously activating the Return to the Underworld Instant Explosion.

'If I'm not mistaken, this Nine Heavens Yin Demon Array has been operating for 100,000 years. Over such a long time, it has accumulated and preserved remnant souls…'

Thinking this, Hui grasped a strand of jet-black thread formed from the instantaneous explosion of the Netherworld, as if wielding a thousand-meter-long blade, and slashed it down directly at the very center of the Burial God Valley...

puff! ! !

The thick loess soil, as if made of paper, was carved with a fissure that was tens of kilometers long and hundreds of meters deep. Hui looked down into the fissure and saw an unfathomable abyss inside.

"This should be the core of the Nine Heavens Capital Yin Demon Formation."

Hui muttered to herself, then her body began to fall freely, plummeting straight into the crevice...

One more chapter, ending this world.

Chapter 244 Devouring

Whizzing--

Hui had been freefalling for several dozen breaths, with pitch-black earthen walls on both sides. All she could hear was the whistling sound of her body falling at high speed and rubbing against the air. Every now and then, protruding earthen and rock walls were smashed by Hui, who was covered by her true qi feather robe.

Meanwhile, the temperature is getting lower and lower.

Hui roughly estimates that it is only 1 or 2 degrees Celsius now, and the temperature is still dropping.

However, this is nothing to a Xiantian martial artist whose true energy has not been exhausted.

And suddenly,

Hui sensed an invisible storm approaching; it was a mental attack. However, this attack was extremely chaotic; rather than an attack, it was more like a powerful emotional interference.

Even a martial artist at the Celestial Realm would be unable to defend against such an attack originating from the soul level.

But for Hui, who possesses a trace of divinity, this emotional interference is merely a gentle breeze.

Several dozen more breaths passed.

suddenly,

Grunt!

Hui felt as if she had been pierced by something.

Then Hui trembled all over because she discovered that the gravity here had reversed. Without hesitation, she immediately used all her lightness skill to dissipate the huge kinetic energy from before and reversed her lightness skill to float in the void.

"Hmm? This is..."

Hui found herself suddenly enveloped in a thick black fog, seemingly in a graveyard. The night was heavy, like dark, cold blood flowing from a rotting corpse, winding its way across the sky and earth. The moon hung lonely in the sky, its light dim, like the resentful tears in a woman's eyes. Everything in the black fog was damp; the bark of the trees and soil seemed to be festering, and a suffocating stench filled the air.

Immediately afterwards, one after another, rotting flesh and exposed bones, emitting a foul stench, crawled out of the soil and swarmed towards Hui. Some had their necks broken, their facial muscles contracted downwards; some had their eye sockets torn open, with one bulging eye hanging out, only connected by the flesh and nerves inside the eyeball; some were completely mangled, with a section of large intestine hanging outside their stomach, from which an unknown dark brown gelatinous fluid flowed... They all rushed towards Hui.

but,

Hui, however, showed no sign of panic.

Because Hui knew that none of this was real; it was just an illusion caused by the influence of her mind.

What influenced it?

Naturally, these are remnant souls so numerous they are almost tangible, capable of breaking boundaries and interfering with the material world.

This continent was in ancient times, in a state of chaos, and very few people were able to die peacefully. Most of them died with their eyes wide open in disbelief. These remnant souls, mixed with various emotions, were captured by the Nine Heavens Capital Yin Demon Array and could not dissipate back into the universe. They were firmly bound within the array.

Even though the emotions carried by these remnant souls were ground to dust by the Nine Heavens Yin Demon Array, leaving only remnants, they still did not disappear.

This accumulation lasted for 100,000 years, and through this quantitative change, a qualitative change occurred, leading to the situation we have today.

However, this meant nothing to Hui, who possessed a trace of divinity.

"break!"

With a low shout, the ethereal soul trembled, and the wisdom spirit felt a refreshing coolness. The terrifying scenery around them shuddered and vanished, instantly freeing him from these illusions.

Only then did Huicai see the whole picture.

This is an enormous underground cavern, tens of thousands of feet high, with a massive circular surface, estimated to be tens of thousands of miles in diameter. It slowly rotates around its axis, and scattered across its vast surface are numerous small buildings, a few meters high and wide, arranged in a seemingly orderly fashion.

The small buildings were connected by a complex network of crisscrossing ditches, and flowing through these ditches was actually a liquid form of various colored internal energy. This energy flowed through the various small buildings, illuminating them in a kaleidoscope of colors and connecting them all together.

From above, the entire altar, spanning tens of thousands of miles, appears as an extremely intricate picture woven from countless colorful lines.

But what's even more incredible is that this is only the top layer of the disk; below it are countless other layers of the same complexity, rotating at different speeds and directions.

"Is this the Nine Heavens Capital Yin Demon Formation, which took people in ancient times a thousand years to build?!"

Witnessing this monumental project firsthand still filled Hui with awe.

However, as Hui gazed at the colorful lines and countless miniature buildings on them, she felt increasingly uneasy...

"How come this looks so much like an incredibly complex... integrated circuit diagram!"

Hui thought about it more and more and it seemed to make sense.

Although this array appears chaotic, with Hui's intelligence, careful observation reveals that there are indeed repetitions. Although the smallest unit of repetition has dozens of variables, dozens of times more than the variables of a transistor composed of diodes and triodes, the fact that it is 'repetitive and contains the smallest unit' means that it is a special circuit, no, it should be called an artificial true energy circuit.

"Could it be that the so-called array formations that have long been lost in this world are actually something similar to a computer?"

"It seems quite possible."

Hui thought about it more and more and it made sense.

Martial artists who can use true qi not only have long lifespans, but their brain development has also reached a level that is astonishing to later generations.

A martial artist may have low emotional intelligence and be bad at interpersonal relationships, but his IQ will certainly not be low.

"So it's strange that martial artists, this superhuman group, haven't invented anything like computers!"

"But this has nothing to do with me."

Hui stopped looking at the so-called great formation below and instead looked at the sky above the Nine Heavens Capital Yin Demon Great Formation.

This is the remnant of its soul accumulated over 100,000 years. Although it is worthless to it, it is a "delicious" tonic for the void soul.

Hui felt a thirst that came from the depths of his soul, like a person who hadn't drunk water for three days suddenly encountering a lake.

"I can't take it anymore, I can't hold back..."

Hui no longer hesitated and completely let her instincts run wild.

"Swallow!"

Splash—

The remnant souls within a kilometer radius of Hui's location vanished instantly. However, this was insignificant compared to the sheer number of remnant souls. The outside world quickly replenished them, forming a soul vortex. The vortex, centered on Hui's kilometer radius, greedily devoured the massive number of remnant souls... As for the emotions within, they were directly reduced to nothingness.

+ 10000000

+ 10000000

+ 10000000

+ 10000000

······

The amount of soul energy continued to increase relentlessly, quickly surpassing one hundred million, two hundred million, three hundred million... one billion, and it was still increasing...

It finally stopped when it reached 9.1 billion.

At this moment, the soul vortex had disappeared, and there was no longer a single soul in the space spanning tens of thousands of miles above the Nine Heavens Yin Demon Array.

Chapter 245 Return

"91 billion? That's about what we expected."

Hui murmured softly.
