What Do You Mean You Set Up a 3000-Layer Formation?

Lu Changsheng laughed for a full incense stick's worth of time, finally venting the fear and frustration that had been pent up in his heart.

He scrambled up from the ground, dusted off his backside, and hummed an unknown tune, strutting deep into the cave dwelling with a swagger that showed no regard for anyone.

Returning to the White Jade Cloud Bed he had crafted with his own hands, Lu Changsheng sat cross-legged and took a deep breath.

It is time to take stock of the spoils from this trip.

He carefully unfastened the Storage Jade Box from his neck.

Even during this process, he couldn't help but feel a pang of heartache over the sliver of Great Dao Merit essence that had been forced out by the Old Earth Dragon's stomach acid.

But when he opened the jade box and saw the two treasures inside, radiating terrifying spiritual energy fluctuations, that heartache was instantly cast to the nine heavens.

"Clack."

Lu Changsheng first took out the broken beast horn and placed it on the white jade bed.

This remnant of a fierce beast king, having had all its destructive will ground away by the grand formation, now appeared as a crystalline, dark red throughout.

Dao patterns of Innate Pure Yang Fire circulated within it, and the heat it emitted was enough to make the surrounding air distort.

This is absolutely a top-tier material for forging a heavy killing treasure with fire attributes.

Lu Changsheng nodded in satisfaction.

However, he had no intention of refining it into a magic treasure.

He was a man of the "cautious path"; once a magic treasure was in hand, one would inevitably have to use it to fight others.

Once a fight broke out, there was a risk of injury and a risk of consuming merit.

This did not align with his survival philosophy.

The best defense is to make it so that people cannot even enter my door.

Lu Changsheng set down the beast horn and lifted the fist-sized Earth Dragon Pearl.

As soon as the Earth Dragon Pearl appeared, the gravity within the cave seemed to increase several times over.

That heavy, dense aura of Earth essence made even Lu Changsheng, a True Immortal, feel that breathing was somewhat difficult.

A Profound Immortal-level Earth essence core.

Lu Changsheng's eyes were glowing.

His mind had already begun to race with frantic calculations.

My previous one thousand eight hundred and sixty-three layers of formations, while numerous, used nothing but junk for foundation. If I were to encounter a Primordial Unity Golden Immortal forcing their way in, they would only be delayed for a few hundred years at most.

But if...

Lu Changsheng held the beast horn in his left hand and the Earth Dragon Pearl in his right.

If I use this Earth Dragon Pearl as the absolute core of the entire mountain-protecting formation and integrate it into the ley lines of this Nameless Low Mountain.

Then my formation will no longer be a tree without roots, but one connected as a whole to the earth for a hundred miles around!

As long as the earth does not sink, my formation will not break!

Moreover, earth gives birth to all things, and earth can support everything. I will use this half-horn as the eye of the killing formation, utilizing the Dao of formations to make the Earth essence and Fire essence complement each other.

The outer layer will be an absolute thick-earth defense, and the inner layer will be a heaven-burning killing formation of Pure Yang Fire. Whoever dares to force their way in and breaks the outer shell will immediately be burned to ashes by the Pure Yang Fire!

The more he thought about it, the more excited Lu Changsheng became.

He felt as if he could already see a truly impregnable, peerless fortress being born by his own hands.

Action speaks louder than words!

Lu Changsheng was a man of action, especially when it came to stacking defenses; he possessed a fanaticism and execution ability that others could hardly reach.

He did not rush to start immediately, but instead closed his eyes and spent a hundred years adjusting his early-stage True Immortal magic power to its peak state.

Afterward, he stepped off the cloud bed and arrived at the deepest part of the cave, where the ley line node of this Nameless Low Mountain was located.

"Go!"

Lu Changsheng pinched a magic seal and tossed the Earth Dragon Pearl into mid-air.

Following that, he opened his mouth and spat out a breath of his True Immortal-level natal true fire, beginning to smelt the Profound Immortal-level treasure pearl bit by bit.

The Earth Dragon Pearl was simply too hard.

Even though Lu Changsheng was now a True Immortal, wanting to completely refine it and integrate it into the ley lines was a project so vast it was despair-inducing.

But the one thing he did not lack was time.

Five hundred years.

One thousand years.

Two thousand years.

There was no alternation of day and night in the cave, only the figure of Lu Changsheng, as still as an old monk in meditation, and the Earth Dragon Pearl in mid-air that was being dissolved bit by bit.

Three thousand years in total.

The moment Lu Changsheng guided the final wisp of earthy-yellow origin power through the array patterns and drove it deep into the ley lines of the Nameless Low Mountain.

"Hum--!"

The entire Nameless Low Mountain, and even the earth for a hundred miles around, let out a dull, resonant boom.

It was not an earthquake, but a qualitative sublimation.

A faint, earthy-yellow halo automatically emerged on the stone walls inside the cave dwelling.

This halo was indestructible; Lu Changsheng casually unleashed a strand of True Immortal-level Sword Qi against it, yet it failed to leave even a single white mark.

"It's done! The first step, ley line integration, is complete!"

Lu Changsheng wiped the sweat from his forehead, his eyes filled with fervor.

He did not stop to rest.

Immediately after, he picked up the severed, dark-red beast horn and began to lay out the core killing array.

Fire-element arrays were incredibly violent; the slightest carelessness would cause the furnace to explode.

Lu Changsheng had to be as meticulous as a woodcarver, carefully etching one miniature array pattern after another onto the beast horn to guide the spiritual energy.

This etching process took another two thousand years.

Five thousand years.

A full five thousand years had passed since Lu Changsheng fled back to his cave dwelling.

During these five thousand years, the struggle between the three clans on the Primordial Land outside had reached a fever pitch.

Countless reclusive powerhouses were dragged into the tribulation, and countless heavenly treasures emerged, accompanied by blood and slaughter.

Yet, in this remote corner tightly concealed by arrays, Lu Changsheng remained as secure as an outsider.

"Rise!"

One day in the five thousand and first year.

Lu Changsheng stood in the center of the cave dwelling, his hands thrusting upward.

The severed beast horn, now covered in dense, intricate array patterns, transformed into a streak of red light that shot straight to the ceiling of the cave, vanishing into a massive stalactite.

At the same time.

The countless array flags and array disks Lu Changsheng had placed around the area seemed to be connected by an invisible thread.

"Boom!"

One thousand eight hundred and sixty-four layers.

One thousand nine hundred layers.

Two thousand five hundred layers.

Three thousand layers!

A full three thousand layers of arrays!

Under the reinforcement of the two top-tier origin materials—the beast horn and the Earth Dragon Pearl—the number of arrays did not simply pile up blindly as before; instead, they underwent a miraculous fusion.

The outer layers of illusion and trapping arrays, supported by the spiritual power of the Earth Dragon Pearl, expanded their range tenfold, capable of easily distorting even the divine sense of a Primordial Unity Golden Immortal.

The middle layers of defensive arrays, infused with the origin of earth, became as heavy as mountains and unbreakable.

The innermost killing array fused with the destructive power of the Pure Yang Fire; once triggered, it could instantly reduce even a Profound Immortal to ashes.

"It's done..."

Lu Changsheng felt the absolute sense of control over his surroundings, where even a mosquito flying in would have to pass through three thousand security checks, and he let out a long, weary breath.

He walked to the white jade bed and sprawled out on his back.

"I'm exhausted. This upgrade drained all my assets; I even melted down that battered Refined Iron Heart-Protecting Mirror to use as an array base."

"But, it was worth it!"

Lu Changsheng stared at the stone ceiling of the cave, grinning like a fool.

"With this Mysterious Yellow Pure Yang Array of three thousand layers, even if that dead loach came back to life and brought his whole family to block my door, I wouldn't be afraid."

"Security—this is what real, solid security feels like!"
