"Whoosh."

From within the void passage, a figure emerged instantly.

Lin Fei's gaze swept across the scene, sensing a strange and fierce power unlike any he had known. He noticed that the numerous threads of the Divine Realm's laws were snapping one by one due to this bizarre energy.

The breaking of these laws was fundamentally damaging the Divine Realm's core. While minor damage might seem negligible, widespread and continuous damage over hundreds or thousands of years could severely harm the Divine Realm. Such extensive damage could bring the Divine Realm to the brink of collapse, akin to smaller worlds.

Unmistakably, the source of this eerie power was the Dark Demons from the Dark Demon Domain, beings from outside the Divine Realm. The Divine Realm's laws inherently repelled these Dark Demons, suppressing a portion of their strength. However, the overwhelming numbers of Dark Demons were pressing heavily on the Yin-Yang Immortal Domain's Martial Gods, Deity Transformations, and True Monarchs.

Amidst the fray was a True Immortal with over ten thousand avatars, struggling against two massive, horned beasts. The True Immortal's formation, composed of these avatars, was barely holding its ground and occasionally losing avatars.

Clearly, these two beasts were the Dark Demon Domain's equivalents of True Immortals or Martial Ancestor.

"Is that... Martial Ancestor Lin?"

"Yes, it's Martial Ancestor Lin, the recently renowned Martial Ancestor Lin of the Ancient Covenant!"

"Martial Ancestor Lin is here. It seems the reinforcements are from the Great Dream Sect."

"One Martial Ancestor Lin from the Great Dream Sect is enough!"

"Martial Ancestor Lin defeated Taihao True Immortal and Azure Mountain True Immortal. He's incredibly powerful."

"We're saved..."

Many martial artists showed expressions of relief and hope. However, the Dark Demons showed no fear upon seeing Lin Fei. Instead, their savage nature emerged as they charged directly at him.

Lin Fei frowned slightly and then extended his hand, pressing lightly towards the swarm of Dark Demons.

"Boom."

Instantly, the void shattered.

Lin Fei unleashed a burst of pure, unadulterated physical strength with a single press of his hand. It was merely the strength of his flesh, yet it was an absolute and pure force. Even across the air, the power was terrifying.

With a soft "pu-chi," this simple press obliterated hundreds powerful dark demons in an instant. A mist of blood filled the air, thick with the scent of carnage.

"What?" the onlookers gasped as they witnessed the mass demise of the dark demons. Two dark demons, each rivaling a True Immortal, roared in fury. A dreadful intent to kill filled the void, their gazes fiercely fixed on Lin Fei. It was clear they recognized him as a formidable adversary of their own caliber.

The spectators from the Yin-Yang Immortal Realm were dumbfounded, scarcely believing their eyes. They knew Lin Fei was powerful, but this was beyond comprehension. His palm had merely pressed against the void, and countless dark demons perished.

Among these demons were many comparable to True Monarchs. Yet, Lin Fei had crushed them into dust from afar—a feat not even a True Immortal could achieve. Was it Martial Ancestor who was too strong, or was Lin Fei himself too formidable?

"Roar..."

At that moment, another group of dark demons flew in from afar.

"Fellow Daoist Lin, these dark demons possess a Dark Heart, left within the Dark Demon Domain," a voice transmitted to Lin Fei's ear. "We have only killed their bodies. They can quickly regenerate as long as they have energy, akin to the avatars of Deity Transformation cultivators."

"Indestructible, are they?" Lin Fei mused. He had already guessed as much.

The Deity Transformation cultivators of the Divine Realm could transform into billions and were essentially immortal. Likely, the dark demons of the Dark Demon Realm possessed similar capabilities. Their Dark Heart remained in the Dark Demon Domain, ensuring their survival regardless of the peril. Even if their bodies were destroyed, they could regenerate from their Dark Heart.

Lin Fei also surmised that this Dark Heart might control the lives of these dark demons. The Dark Heart was possibly the essence of their existence. The Dark Demon Lord needed only to control the Dark Heart to have complete dominion over these beings, without fear of betrayal.

However, Lin Fei was not overly concerned. Being indestructible did not mean there was no cost. To regenerate a dark demon from its Dark Heart surely required a significant price. For instance, it demanded a vast amount of energy. And such energy was not easily obtained. If too many dark demons were lost, it might become challenging to continue their regeneration. Regeneration would also take time.

Nevertheless, there were indeed many dark demons. With a wave of his hand, the mighty ones of the Great Dream Sect also made their appearance.

"Go forth. Stop the Dark Demons."

The members of the Great Dream Sect saw the Dark Demons. They weren't afraid of these god-level or True Monarch-level creatures and quickly charged at them. Lin Fei wasn't overly concerned about these Dark Demons. Even if the Great Dream Sect members failed, he could instantly use the Eternal Realm to crush them all.

Lin Fei focused his gaze on the two Dark Demons comparable to True Immortals. He knew that the outcome of this invasion war wouldn't be determined by ordinary martial artists. No matter how many god-level or True Monarch enemies they killed, it wouldn't make a decisive impact. The true key to victory lay at the True Immortal and Martial Ancestor levels.

After all, deciding the outcome or killing an opponent at the Supreme level was extremely difficult. Moreover, the Supremes were battling in the chaos outside the Divine Realm. However, True Immortals and Martial Ancestors had descended into the Divine Realm, posing a direct threat that had to be dealt with.

Without hesitation, Lin Fei made his move.

"Eternal Realm!"

"Boom."

Lin Fei transformed into the Eternal Realm. When he wasn't unleashing his power, it wasn't evident, but once he did, the sheer might was earth-shattering and terrifying to the extreme. A massive world materialized in the void, swiftly enveloping the two powerful Dark Demons and the True Immortal.

Lin Fei immediately teleported the True Immortal out of harm's way, but the two Dark Demons weren't so fortunate. Their bodies expanded, wreaking havoc within Lin Fei's Eternal Realm. Lin Fei's realm trembled violently, as if on the verge of collapse.

Lin Fei's eyes were cold.

"Eternal Realm, annihilate!"

Lin Fei aimed to "annihilate," not merely "suppress."

A boundless killing intent spread madly. Even the two Dark Demons sensed the imminent danger. Although their power was immense, Lin Fei's Eternal Realm was stronger. He forcibly suppressed the two Dark Demons.

Moreover, the power of the Divine Realm itself was also suppressing the two Dark Demons.

"Bang."

Finally, one Dark Demon couldn't withstand it and was crushed into powder by Lin Fei's Eternal Realm. The other Dark Demon, however, managed to tear through Lin Fei's realm, a first-time occurrence!

"Illusory Realm."

Lin Fei remained unperturbed. As the Dark Demon tore through the Eternal Realm, attempting to escape, he unleashed the Illusory Realm.
