My military branches can Evolve Infinitely

On the northern edge of the Ten Directions Island Domain, the Realm Passageway leading to the Red Mist Land narrows down to merely a few hundred meters wide. It is perpetually surging with vast energy tides, making it impossible under normal circumstances for ordinary monsters to breach the boundary wall.

The monsters within the Island Domain typically originate from within its territory.

However, when the monster population accumulates to a critical point, converging into an overwhelming tide, the annihilated monsters and energy tides neutralize each other, gradually diminishing the tide's intensity, allowing the monsters to surge into the domain en masse.

What's more, many times these monster tides are led by World-level strongmen, and even Law Realm Grand Dukes.

Law Realm wielders command immense power and can easily suppress the energy tide, enabling the monster tides to traverse unimpeded.

"But this time, it's different again."

Mu Yuan gazed into the distance.

Darkness, red mist, mountains, ominous clouds—they could not hinder his vision at all.

At the edges of his sight, the thick red mist resembled wave after wave of scarlet titanic surges, crashing upon the Island Domain from beyond.

The entire Ten Directions Island Domain felt like a small, isolated island in a raging ocean, helplessly enduring the colossal waves until…

"Boom~!"

It was as though something had shattered.

The deafening sound didn't exist in the physical world but within the conceptual plane.

From Mu Yuan's perspective, on the conceptual dimension, the entire Ten Directions Island Domain was encased within the boundary wall. This barrier bore multiple 'loopholes,' which formed the traversable Realm Passageways and the weak points of the entire wall.

But at this moment,

"Crack~ Crack~!"

The walls surrounding the Realm Passageway began fracturing under the impact of the scarlet tides, before crumbling completely in an instant.

What was once a confined passage transformed into a broad corridor within moments.

It was akin to a section of a fortress wall collapsing entirely.

Countless monsters—millions upon millions—flooded into the Ten Directions Island Domain, occupying every inch of land within this territory.

They bared their fangs, roared incessantly; their arrival further defiled this soil.

"The current number of monsters invading our domain is approximately equivalent to six waves of super tides. With time, this number will only continue to grow."

Inside the Ancient Mage Tower, using this Legendary Building for reconnaissance, Isloa spoke.

"However…"

She paused momentarily before adding, "For now, no Law Realm monsters have been detected. But we cannot rule out the possibility that Law Realm Grand Dukes are lurking within the monster tide."

After all, with the sheer multitude of monsters, combined with the current phase of the full moon and the surge of scarlet mist tides...

The Ancient Mage Tower's detection capabilities were, at best, mediocre, and even Isloa's ability to peer into the threads of fate couldn't uncover the existence of Law Realm entities veiled amidst the countless threads of monster destinies.

If there were any.

If not, it would still be reasonable.

Law Realm monsters had long grown hesitant to infiltrate the Ten Directions Island Domain. These successive monster tides seemed more like naturally occurring phenomena. The Ten Directions Island Domain, as the solitary bastion against the Red Mist Land's catastrophe, was naturally subjected to enormous impacts.

Jun, stationed within his territory, soared into the skies, swiftly circling the Island Domain several times.

With his piercing gaze, he scanned the land thoroughly, even penetrating through the monstrous tides.

Still, there was nothing significant to be found.

"Indeed, mere monsters dare not invade our Tianyuan City!"

"Should one come, I, Lord Jun, shall slay a pair!"

Jun hovered high above the Azure Sky, his gaze sharp and commanding.

Although conflicts were erupting across the world and many strong territories were facing potential ruin, Tianyuan City was a monster's forbidden ground!

Their superiority was undeniable.

Mu Yuan stroked his chin, "The current situation isn't problematic, but…"

The numerous monster tides would accelerate the pace of corruption and pollution.

This wasn't a significant concern; it could be cleaned away with ease.

Without monster commanders holding positions of power, the vast number of monsters posed no real threat—dealing with them was merely a matter of time, often requiring less time than anticipated.

As for monster strongmen, as Jun had aptly said, they dared not enter the Ten Directions Island Domain carelessly.

Even if World-class monsters or Law Realm monsters were hidden within the tides, planning to exchange lives with Tianyuan City's elites and warriors, Mu Yuan wouldn't mind.

Even if an elite legion were to be wiped out in the wilderness, he would remain indifferent.

He still had the Legendary Building, the Heroic Spirit Hall, as his safeguard.

Furthermore, Law Realm Grand Dukes, as high-ranking figures in Overlord Powers, wouldn't be offered just to exchange for ordinary strongmen here.

Mu Yuan was unconcerned.

But…

At this moment, the more serene the enemies appeared, the more tumultuous the undercurrents beneath the surface undoubtedly were.

He didn't believe the Dragon Sleep Valley would remain indifferent.

Nor were the surrounding top-tier monster overlords unlikely to target Tianyuan City.

After all!

Tianyuan City's geographical location was abysmal.

Standing at the forefront of the Spiritual Territory, it resembled an enormous reef. Should the Red Mist waves aim to continue surging southward, they would first have to pummel and shatter this resolute reef of Tianyuan City.

Mu Yuan was convinced the enemies were already scheming.

"We must not let down our guard."

"However, crises also bring opportunities. Now that I possess the Evolutionary Miracle Building's authority, though my slots for evolution are limited, evolving anything requires a base of Epic Buildings. The more types of Epic Buildings we have, the greater chance of evolving structures that our Tianyuan City needs the most."

Mu Yuan commanded Jun to continue patrolling.

...

At this moment,

On the outskirts of the Ten Directions Island Domain, deep within the monster tide.

Two nondescript Law Realm Grand Dukes wiped cold sweat from their brows.

"That King of Cangqing just flew past again! Dear heavens!"
