Mortal Intruders, Nothing Left with a Single Thought

At that moment, the Abyss of Causelessness completely lost the concept of "boundaries".

It's not that space collapsed, but that existence was erased from its reference point.

The Silent Profundity Origin Heart Demon slowly raised its head, and its final form finally appeared—it could no longer be called a "form," but rather a personified "Silence." Its outline was no longer stable, sometimes resembling a person, sometimes an abyss, and sometimes transforming into a Nameless shadow covering the heavens and the earth.

It has no facial features, but where a face should be, countless overlapping "blanks" appear, each reflecting a world that is heading towards its end. Its body is composed of extremely fine gray-white dust, which is not energy, but the lingering echo of existence after being obliterated, slowly settling around it like endless snow.

When it stands fully upright, the Abyss of Causelessness is no longer silent. All sounds, fluctuations, and thoughts automatically return to zero the moment they approach it.

This is the true meaning of "silence"—not destruction, but making destruction itself meaningless.

The will of the Silent Profundity Origin Heart Demon descended, carrying no pressure, yet more suffocating than any pressure:

"You have seen the Unborn." "You have also seen Annihilation." "But you, you still journey on."

The next instant, its third and final supernatural power was unleashed.

"Eternal Silence Devouring". Silent. Lightless. Without process.

Qin Yu didn't even see the attack happen—he only sensed his soul being "extracted from concept" before a thought could fully form. It wasn't being pulled, but rather being defined as something that should return to Eternal Silence.

A realm Abyss of Causelessness of No Return. It was neither darkness nor nothingness, but a state of "no possibility of distinction": no thought, no idea, no birth, no death. Once absorbed into it, the cultivator would no longer be a loser, but would become part of the Key of Silent Profundity, eternal, silent, and irreversible.

Qin Yu's consciousness began to fade. It wasn't that he was unconscious, but rather that "his consciousness itself was being simplified."

In that instant, he did not resist.

He did not struggle, nor did he resist the devouring force with his will. He simply allowed his soul to sink willingly as it was pulled into Eternal Silence, as if going with the current. Because he understood that this supernatural power was not meant to destroy him, but was waiting for an answer—when "silence" truly descends, will you still need to prove your existence?

At the Threshold point of being completely absorbed into the Realm of Eternal Silence, Qin Yu spoke in a low voice:

"I don't resist." Eternal Silence Devouring slightly.

Qin Yu continued, his voice steady, yet carrying an extremely clear sense of self-affirmation:

"I do not resist Annihilation, nor do I resist becoming Nameless."

"But what I refuse is being defined by when I will pass away."

In that instant, he used himself as an anchor to once again activate "The Void Source: Dream Stillness of Silence," but instead of expanding the domain, he allowed the three incompletely manifested states— the Void Source Domain, the Realm of the Unborn, and the Domain of Annihilation —to form an inward superposition within his body. It was not about erasing the outside world, but about allowing himself to simultaneously possess the dual narrative space of "Unborn" and "unsilent."

Immediately afterwards, he used the "Three Forms of Fate Construction of Cause and Effect Deconstruction".

It's not about dealing with inner demons, but about deconstructing the causal relationship of "being devoured" itself.

In an instant, a very thin crack appeared in the Realm of Eternal Silence.

It wasn't a spatial rift, but a definitional rift—the logical premise of "cultivators being Eternal Silence Devouring" was forcibly dismantled. Qin Yu didn't deny the rationality of Annihilation, but rather stripped away the causal link of "Annihilation is necessary at this moment." For the first time, the Eternal Silence region that should have completely encompassed him hesitated.

In that instant, he raised the Silent Origin Stainless Sword.

"The Undefined Destruction Sword." This sword strike has no target.

It cuts through the concept of "it must be this way".

As the sword fell, the final form of the Silent Profundity Origin Heart Demon trembled violently, and its body, composed of countless echoes of existence, began to lose its stable direction of returning to stillness. For the first time, it emitted a wave that resembled a sigh—not pain, but confirmation.

I confirmed that the person before me was not one who resisted Annihilation.

Rather, it is an existence that retains the right to choose even in Annihilation.

The Abyss of Causelessness then fell silent.

The Silent Profundity Origin Heart Demon slowly retreated, its form disintegrating layer by layer, transforming into countless gray-white dust particles, and merging back into the abyss. Its last thought echoed within the abyss:

"Entry is permitted." At this moment, the Key of Silent Profundity fully revealed its true core.

It was no longer a simple key, but an extremely condensed point of mysterious light, as if it were superimposed from the four states of "Unborn," "born," "about to be silent," and "not yet silent." It quietly floated in the deepest part of the Abyss of Causelessness, without any pressure, yet Qin Yu clearly perceived for the first time that this was not the granting of power, but the transfer of authority over existence.

Qin Yu stretched out his hand, and before his fingertips even touched it, the entire Abyss of Causelessness began to slowly retract, as if this trial ground itself was waiting for a new home.

The Abyss of Causelessness froze completely the moment Qin Yu touched that point of mysterious light.

It's not that time has stopped, but rather that the judgment of whether everything "continues to exist" has been temporarily revoked.

The Key of Silent Profundity —or rather, the unnamed "Causeless Profound Key"—slowly materialized before Qin Yu's fingertips. It was not a real object, but a state between "being perceived" and "being denied": the outline of a dark, black crystal key emerged from nothingness, its surface devoid of patterns, yet seemingly containing countless unfinished worlds. Its mystical light did not radiate outwards, but rather collapsed inwards, as if constantly trying to return itself to its "unborn" state.

Qin Yu had clearly touched it, but he couldn't feel any temperature, weight, or even "touch." There was only an Ultimate silence that spread from his fingertips all the way to the deepest part of his Fate Soul.

At that very moment, the true mechanism of the Key of Silent Profundity was activated. It wasn't about recognizing a master, but rather about carrying out a selection process.

Qin Yu's Fate Soul was forcibly pulled into the Silent Profundity core within the key, a core devoid of cause and effect, past and future. He clearly sensed his own level of existence being dismantled—the thought structure upon which the Void Emanation Realm relied, a fusion of the real and the illusory, permeating the Wuji, was being peeled away layer by layer; the continuity of time collapsed within his body.

His sense of spatial orientation rapidly dissipated. His "self" was being guided towards a higher, more dangerous state—not a breakthrough, but rather a prematurely shaped container for a state of Silent Profundity.

If this step is taken in accordance with the natural flow, the Key of Silent Profundity will shatter and merge directly into the divine soul, forcibly completing the leap.

But Qin Yu did not.

Just before his Fate Soul was about to be completely locked into the "Silent Profundity Vessel", he took the initiative to activate his existing fundamental structure - "Three Forms of Fate Construction of Cause and Effect Deconstruction of Cause and Effect".

It's not about attacking the Key of Silent Profundity, but about dismantling the causal chain that "must merge at this moment."

At the same time, using *The Origin of Void Source: Dream Stillness * as a starting point, he did not expand his domain, but merely formed a tiny "Unborn -unsilent" buffer state within his body, allowing his existence to briefly exist in a void where it neither advances nor retreats. Immediately afterwards...

He used "Time Flow Reversal" not to go back in time, but to reverse the timeline of "fusion completion", thus forcibly delaying the judgment of the Key of Silent Profundity on him.

This series of actions was not an act of resistance against the Key of Silent Profundity, but rather a clear declaration to it—I accept you, but not at this moment.

Deep within the Abyss of Causelessness, for the first time, the fluctuations of the Silent Profundity Origin showed a feedback resembling "acknowledgment." The Key of Silent Profundity did not shatter.

It slowly withdrew the power that had attempted to solidify Qin Yu's form, retreating from the depths of his Fate Soul, establishing an extremely subtle relationship between the two—not master-servant, not a contract, but a resonance state that was allowed to "temporarily exist." The dark, mysterious crystal key fully materialized, its outline stabilizing, yet it remained half-real and half-illusory, sometimes clear, sometimes hidden, leaving only a trace of mysterious fluctuation in Qin Yu's perception.

At that moment, Qin Yu understood its name and essence perfectly.

The Key of Silent Profundity. Also known as the Causeless Profound Key, or the Annihilation Profound Crystal.

It is not the direct source of power, but rather the only legitimate entrance to the "Silent Mystery Realm." When necessary, it can dismantle the timeline and obliterate spatial boundaries, allowing the soul to briefly immerse itself in the Silent Profundity of "no cause and effect, no before and after," nurturing Unborn possibilities; it can also be used in battle...

It forces enemy attacks into an insurmountable void, rendering them ineffective. However, it is equally dangerous—overuse will cause the user to gradually Annihilation until even a "breakthrough" is no longer necessary.

Throughout history, very few have actually used this key to enter the Silent Mystery Realm.

At that moment, Qin Yu merely held the key; he did not open the door.

The Abyss of Causelessness began to slowly recede, Key of Silent Profundity completely disappeared from Qin Yu's palm, leaving only a very faint black mark that sank into the deepest part of his Fate Soul. The next instant, space lost its meaning, and existence was returned to its original orbit.

Qin Yu felt a slight sensation of weightlessness pass by.

When his senses returned, he found himself once more deep within the Shadow-Devouring Forest of No Return. The forest was still vibrant with spring, yet an indescribable silence had settled over it.

Those were traces of the Abyss of Causelessness that had once been opened. The aura of the Key of Silent Profundity was perfectly concealed, as if it had never appeared, but Qin Yu was absolutely certain that it had become an inseparable part of his Fate Soul structure.

He looked up at the light and shadows in the woods and murmured to himself.

"So that's how it is... Above the Void Evolution, it really isn't power, but rather the 'choice of whether to continue existing'."

This time, he didn't break through. But he was already standing at the door.

The springtime atmosphere of the Shadow-Devouring Forest of No Return was suddenly thrown into chaos in that instant.

The originally gentle and flowing light and shadow in the forest were suddenly disrupted by an invisible hand. The shadows of the trees were lengthened and twisted, Void Evolution ripples appeared in the air as if they had been forcibly torn apart. More than a dozen figures almost broke through the air and landed on the edge of the broken ancient formation outside the forest.

The dozen or so disciples of the Asura Immortal Hall at the Void Emanation Realm · Supreme, who were at the forefront, were surrounded by Sha Qi. Blood-red Asura patterns were faintly visible on their protective auras. The two figures standing at the back were like two still abysses—elders at the Silent Mystery Realm · Supreme, whose auras were restrained yet so heavy that even the space beneath their feet slightly sank.

"Who goes there—" the leading disciple shouted, his voice like a blade cutting through the forest, "How dare you trespass into the forbidden area of my Asura Immortal Hall!"

Before the words were even finished, one of the elders' gazes were already fixed on Qin Yu, his pupils shrinking as if confirming something from a bloody memory. "It's him... the person from the image in the Nine Alliances Gang's wanted poster. There's no mistake. Kill him! No matter what he's doing here, trespassing on our forbidden territory—kill him without mercy!"

Without hesitation.

In the next instant, more than a dozen disciples at the Void Emanation Realm · Supreme stepped forward simultaneously, their hand seals flying, and Asura -type divine abilities exploding in the forest. Crimson phantoms, the Realm Breaking- Breaking Wheel, and the Cause and Effect Tearing Seal intertwined, as if the world had been pulled into a high-speed slaughter machine. The air was cut into fragments, the ground collapsed in patches, and violent energy waves rushed straight towards Qin Yu's location.

Qin Yu simply stood still. He didn't even fully raise his head.

Lin Feng brushed against his sleeve, his gaze cold and almost indifferent, as if watching a farce whose ending he already knew. "Hmph—you think you can take me?"

In that instant, the entire Shadow-Devouring Forest of No Return seemed to have been silenced.

Qin Yu took a step forward, the Silent Origin Stainless Sword not drawn. He merely raised his right hand, fingers slightly spread, and the structure of his Fate Soul began to operate with a roar—

At this moment, "The Three Forms of Fate Construction: Cause and Effect Deconstruction" was pushed to its Limit. There were no dazzling beams of light, but countless visible lines of cause and effect appeared in the void, spreading out like a silver-gray spider web, precisely binding the Asura God that were erupting.

Then, he uttered a single word in a low voice. "Break."

In an instant, the "preconditions" for the establishment of all supernatural powers were simultaneously removed. The blood-red slashing wheel collapsed suddenly in mid-air, the Cause and Effect Tearing Seal lost its direction and turned into meaningless energy debris, and the illusory Asura seemed to have its "reason for existence" erased, directly exploding into countless light fragments in the air.

Qin Yu did not stop. He compressed "Void Source: Dream Stillness" to an extremely small release scale, without expanding the domain, but only condensing it into a projection of "Existence Zero Point" in front of him.

That midnight was silent and lightless, yet it was like a black nail forcibly embedded in reality.

It swept across the battlefield. Not with an explosion, but with deletion.

The figures of more than a dozen disciples at the Void Emanation Realm · Supreme froze abruptly as midnight passed. Before the roars, killing intent, and even fear on their faces could even take shape, they were abruptly pulled from the moment of "what was happening".

There was no bloodshed, no remains; their existence was as if they had been cut from the narrative by scissors, leaving only a few lingering ripples of energy on the ground, proving that people had once stood here.

Before the aftershocks had subsided, two elders at the Silent Mystery Realm · Supreme simultaneously made their move, attempting to stabilize themselves with a higher-level Silent Profundity Structure, but Qin Yu's gaze had already fallen upon them.

He then invoked "Time Flow Reversal," not as a retrospective attack, but by dragging "the point in time when they were not injured" backward for a moment. Immediately afterward, the remaining logic of "Existence Erasure" fell like a cold judgment.

Boom--Boom--Boom--

The two elders were simultaneously blasted away, crashing heavily into the forest floor. Their protective Silent Profundity shattered inch by inch, and they coughed up blood, their auras plummeting instantly. They barely managed to stand up, their eyes filled with undisguised horror and incomprehensible fear.

"This... this is impossible..." one of them stammered, "He's clearly only at the Void Emanation Realm · Supreme... how could he... how could he possess such a logical ability to erase supernatural powers..."

Qin Yu stood before them. The forest breeze began to flow again, and spring returned, but it could no longer conceal the deathly silence that had lingered in that moment. He did not answer, but merely glanced at them indifferently, as if weighing whether a further step was necessary.

The Shadow-Devouring Forest of No Return fell completely silent at this moment.
