The spirit realm concludes, the immortal realm issues a warning.

Outside the Lingyuan Forbidden Land, Nightmare's figure stepped out from the churning black mist of Evil Qi.

The sky outside was murky and dim, filled with the heterogeneous and oppressive Spiritual Qi unique to the Spirit Realm. Compared to the pure, extreme Reverse Path Evil Qi within the Forbidden Ground, the energy environment here seemed chaotic and weak.

Nightmare stood in mid-air, his aura completely restrained beneath his black robes. If not seen with one's own eyes, it would be almost impossible to sense the terrifying power within his body, enough to shake an entire realm. At the Peak Late Tribulation Crossing stage, with two dao reversal keys on him, he was truly invincible in this Spirit Realm at this moment.

But there was no hint of pride or laxity in his eyes. Although the Spirit Realm's heavenly dao core had been destroyed, its scattered remnants, especially those strongholds loyal to the Heavenly Dao, remained a hidden danger. He was about to head to the higher-level Immortal Realm to find the third dao reversal key; he had to ensure that his backyard in the Mortal Realm and this newly subdued Spirit Realm would not catch fire.

"star dao fruit, guide me to the last one."

Sinking his mind, he communicated with the star dao fruit emitting a hazy starlight within his body. Soon, a clear sense of direction came—a valley in the central Spirit Realm, shrouded by a Concealment Formation.

"Heavenly Dao Branch Altar... the last one."

Nightmare's eyes were indifferent. With a slight flicker of his figure, he disappeared from the spot. When he reappeared, he was already thousands of miles away. Space seemed to lose its meaning beneath his feet; the ability of Dao Reversal Shuttle, combined with his Late Stage Tribulation Crossing Stage cultivation, made his speed reach an inconceivable level.

Before long, a seemingly ordinary, Spiritual Qi-sparse desolate valley appeared before his eyes. The outer perimeter of the valley was arranged with extremely sophisticated Illusion Formations and Isolation Formations, enough to deceive the investigation of any Cultivator below the Tribulation Crossing Stage. But in Nightmare's eyes, that layer of hidden light curtain was like nothing; he could clearly "see" the scene inside the valley—

A small but solemn White Jade Palace sat in the valley, with faint golden Heavenly Dao Luck flowing above it. Inside and outside the palace, about ten auras were active, all at the Peak Spirit Transformation cultivation, dressed in uniform white robes with solemn expressions, either patrolling, meditating, or processing documents and artifacts containing the Heavenly Dao aura.

This was the last stronghold of the Spirit Realm's Heavenly Dao scattered outside, responsible for monitoring the Spirit Realm's movements and receiving sporadic Heavenly Dao faith. It was also the tail that Nightmare had deliberately left behind for the purpose of "fishing" and complete eradication when he previously swept through the Spirit Realm's heavenly dao core.

Nightmare had no intention of stealth or observation.

He appeared directly above the valley, looking down from a high vantage point at the White Jade Palace.

"Who is it?!" "Enemy attack!"

The ten Peak Spirit Transformation Cultivators in the palace reacted extremely quickly, instantly becoming alert. Amidst the sharp shouts, streaks of protective spiritual light rose, and two people quickly rushed toward a certain spot in the palace, seemingly wanting to activate a stronger defensive Formation or send a message.

Unfortunately, it was too slow.

Nightmare didn't even make any hand signs or incantation movements. He just had a single thought.

"Buzz—!"

With him as the center, the dark red Dao Reversal Demonic Star Flame spread out silently like ripples from a giant stone thrown into a calm lake, completely enveloping the entire valley and that White Jade Palace in the blink of an eye!

The flames were not scorching or dazzling; instead, they carried a depth and coldness that swallowed light. Wherever it passed, the rocks and vegetation of the valley did not burn but "disappeared" directly, like a pencil drawing erased by an eraser, turning into the most basic energy particles.

Those sophisticated Illusion Formations and Isolation Formations vanished together without even a single ripple.

For the Heavenly Dao Cultivators outside the palace, their protective spiritual light shattered like soap bubbles in the sun the moment they touched the dark red flames. They didn't even have time to scream before the horror on their faces froze forever; their bodies quickly blurred and dissipated in the flames, their Divine Soul fluctuations completely crushed and reset to zero by the Reverse Path Laws contained in the flames.

Inside the palace, the two people trying to activate the Formation had their fingers just touching the Formation Plate.

The dark red flames had already surged into the room like a tide from the doors, windows, and even every crack in the walls.

"No—!"

The desperate roar came to an abrupt end.

As the flames brushed past, everything in the palace—people, objects, Formations, and even the Jade Slips and documents carrying the Heavenly Dao aura—all turned into nothingness in the same instant.

The entire process took less than three breaths.

Nightmare floated in the air. Below, where the valley had been, only a smooth, mirror-like, circular giant pit a hundred feet deep remained. The walls of the pit showed a glazed texture instantly crystallized by high heat, devoid of any grass, and not a single trace of energy residue or life aura remained.

The Heavenly Dao Branch Altar, along with the ten Peak Spirit Transformation guards within it, was completely erased from the Spirit Realm, leaving no trace.

Nightmare didn't even glance at the giant pit. He slowly raised his head, his gaze seemingly piercing through the layered space and clouds of the Spirit Realm, sweeping over the Divine Thoughts hidden in various places, watching the developments here either openly or secretly.

He knew that the various local forces of the Spirit Realm—Immortal Sects, Demonic Sects, Yao Race, Ancient Clans... at this moment, there must be many eyes, near or far, brazenly or cautiously, watching this place, watching his figure as he wiped out the last Heavenly Dao stronghold in one fell swoop.

It was time.

Nightmare closed his eyes, and his Divine Soul power, as vast as an abyss, mixed with the unique pressure of the Dao Reversal Demonic Star Flame that made all Laws tremble, exploded and spread in an unstoppable manner, covering all major areas of the entire Spirit Realm!

It was not an attack, but a declaration.

A cold, domineering, and unquestionable Divine Soul voice, like Nine Heavens thunder, exploded simultaneously in the hearts of all the leaders and powerhouses of any significant force in the Spirit Realm:

**[The Heavenly Dao has been defeated; Reverse Path is coming.]**

**[From now on, the Spirit Realm's order shall be determined by me, Nightmare.]**

**[Anyone who dares to hide, collude with, or attach themselves to the remnants of the Heavenly Dao—]**

**[Their end shall be like this altar! Divine Souls extinguished, legacies destroyed!]**

The four short sentences, each word seemingly carrying the weight of blood and fire, containing the terrifying pressure of the Peak Late Tribulation Crossing stage and the chilling killing intent of the Reverse Path Laws, smashed heavily upon the Divine Soul of every listener!

"Pfft!" "Ugh!"

Throughout the Spirit Realm, countless Cultivators who were secretly peeking suddenly turned pale. Those with weaker cultivation even spat out blood directly, their Divine Souls injured, their eyes showing boundless fear.

Those force leaders who still held a sliver of fantasy about the Heavenly Dao or had secret contact with its remnants were now even more ashen-faced and trembling all over. They clearly felt that the undisguised killing intent in that Divine Soul transmission was by no means a threat. The scene of the valley branch altar instantly annihilating still echoed in their minds.

Absolute force, iron-blooded crushing, clear warning.

No detours, no conditions to speak of.

Those who comply may survive; those who resist will surely die.

The entire Spirit Realm fell into a deathly silence at this moment. All undercurrents and small thoughts were forcibly suppressed under this domineering declaration. At least on the surface, no force dared to have the slightest connection with the words "Heavenly Dao" anymore.

Having done all this, Nightmare slowly withdrew his Divine Soul power.

However, at the very moment his Divine Soul returned to his body, the star dao fruit at his brow and the two dao reversal key imprints floating in his palm simultaneously sent out an extremely subtle yet sharp throb!

It didn't come from within the Spirit Realm.

But from higher up, from the place that vaguely bordered the Spirit Realm but was separated by endless Spatial Turbulence and Law barriers—the Immortal Realm!

A vast, majestic Divine Thought full of a sense of orderly oppression, like a light curtain scanning heaven and earth, was forcibly piercing through the fragile spatial membrane between the Immortal Realm and the Spirit Realm in a crude manner, sweeping toward the Spirit Realm, especially the area where strong Reverse Path fluctuations had just erupted from his Fusion with the lingyuan reverse key and the wiping out of the branch altar!

This Divine Thought was so strong that it far exceeded the Tribulation Crossing Stage, carrying a pure and high-and-mighty "Heavenly Might." It clearly belonged to a powerful existence within the immortal realm heavenly dao system!

The other party had already noticed the movement of the lingyuan reverse key being taken, and had locked onto the general location of the Spirit Realm!

"They came quite fast." A cold light flashed in Nightmare's eyes.

Although he was not afraid of ordinary Cultivators from the Immortal Realm now, the overall strength of the Immortal Realm was far beyond what the Spirit Realm could compare to, and its Heavenly Dao system was more complete and powerful. At this moment, he had just fused the second dao reversal key; although his strength had increased greatly, it was not yet completely stabilized, and his forces in the Mortal Realm had not been fully integrated. It was not the best choice to have a head-on conflict with the Heavenly Dao powerhouses arriving from the Immortal Realm in the Spirit Realm right now.

Moreover, his goal was the third immortal firmament path-reversal key. Before that, it was not advisable to start a full-scale war with the Immortal Realm's heavenly dao core forces too early.

His thoughts spun, and Nightmare made a decision in an instant.

The Spirit Realm's loose ends were cleared, the warning was sent, and the goal was achieved. This place was not suitable for a long stay.

Without any hesitation, he glanced once more in the direction where the Immortal Realm's Divine Thought was coming from, a cold arc curling at the corner of his mouth.

"Want to intercept me? Then let's see if you can catch up."

Before his voice fell, the space around him suddenly twisted, and dark red Demonic Flame enveloped his body.

"Dao Reversal Shuttle!"

"Rip—"

Space was forcibly torn open, and Nightmare stepped into it, his figure disappearing. He didn't return directly to the Mortal Realm but first shuttled toward the edge of the Spirit Realm, where the space was relatively thin and chaotic, his trajectory erratic, intended to interfere with any possible tracking.

Less than ten breaths after he disappeared.

"Boom!"

Above the valley's giant pit, space rippled violently, and a phantom of a giant eye condensed purely from brilliant immortal light slowly emerged. The eye was cold and heartless, scanning the completely flattened valley below and the lingering, heart-palpitating aura of Reverse Path and Demonic Flame in the air.

"Reverse Dao Power... and the aura of Lingyuan... It was indeed taken away."

"The lingering aura is still fresh; he just left."

"Chase! He must be fleeing toward the Lower Realm! Block all stable Spatial Nodes leading to the mortal world below! Send out the Sky Patrol Guard to search the Spatial Turbulence!"

"We must not let the Son of Dao Reversal leave safely with two dao reversal keys!"

Majestic and vast Divine Thought fluctuations echoed in the void, and the immortal light eye slowly dissipated.

Meanwhile, Nightmare had already turned into an elusive streak of dark red light within the endless Spatial Turbulence, speeding toward a certain hidden Spatial Node connecting the Spirit Realm and the Mortal Realm.

The matters of the Spirit Realm were temporarily concluded.

Next stop, return to the Mortal Realm to integrate forces. Then... it would be that higher and more dangerous battlefield—the Immortal Realm!
