Cultivation of immortality begins with an eighty-year-old eunuch.

"boom!"

The purple demonic star, carrying world-destroying kinetic energy, crashed heavily onto the land of Tiannan Star.

The entire planet Tiannan trembled violently. A vast and boundless continent collapsed instantly under this terrifying impact, the earth's crust cracked, and countless underground water veins poured out.

The demonic star was deeply embedded in the earth, and terrifying demonic energy spread from it, turning the flooded seawater into a pitch-black color.

As time passed, that collapsed land eventually transformed into a boundless black ocean.

And so the overwhelming demonic energy began to spread across Tiannan Star, giving birth to countless cruel and ruthless demonic cultivators.

The image then freezes completely and disappears.

Chen Fan stood blankly in the void, his mind buzzing, his heart filled with unprecedented turmoil.

Utterly shocked!

"The Boundless Sea... the gathering place of demonic cultivators from Tiannan Star..."

Chen Fan muttered to himself, "So, the Boundless Sea was created by a demonic star that transformed from the body of the ancient demon Luo Sha after his death!"

He finally understood.

No wonder the demonic cultivation practices in the Boundless Sea are so domineering, no wonder the demonic energy there is so pure.

Because that was the place where the ancient demons fell!

What you see is only one ten-thousandth of my power back then.

The voice of Luo Sha's remnant soul rang out again, pulling Chen Fan back to reality from his shock.

"Now, do you know what kind of heaven-defying destiny you are about to inherit?"

Chen Fan took a deep breath, concealing the shock in his eyes, and regained his composure.

"This junior understands. The greater the fortune, the more difficult the test. Senior, please begin the first trial." Chen Fan's tone was extremely calm.

"Good lad, you've got some of my old temper!"

Luo Sha's remnant soul laughed heartily, then raised his hand and gently swiped it towards the void where Chen Fan was.

"First stage: the formation. Activate!"

"Boom!"

As Rosa finished speaking, the starry sky around Chen Fan suddenly began to distort violently. In the blink of an eye, the surrounding environment underwent a dramatic change.

When his vision cleared again, Chen Fan found himself no longer in the starry sky, but standing on a boundless ocean.

The sea breeze howled, and the waves surged.

When Chen Fan unfolded the meaning of the Fixed Word Technique and carefully looked at the sea, he immediately felt a chill run down his spine.

This isn't seawater at all!

Every drop of water surging in this ocean is formed by countless extremely tiny and incredibly complex array runes!

Those rolling waves, deep whirlpools, and rising mist are all formations!

Endless array formations, large arrays nested within smaller arrays, killing arrays linked to illusion arrays, interlocking and perfectly fused together, forming a sea of ​​array formations that stretches as far as the eye can see!

"hiss……"

Chen Fan, who was already proficient in formations, couldn't help but gasp when he saw this sea of ​​formations.

He once used a sixth-grade array to scheme against the Fire Source in the underground ruins, and he believed that his array skills were already at their peak in the Nascent Soul stage.

But now, facing this sea of ​​array formations, he felt like a young student who had just learned to write, facing a vast and magnificent collection of ancient and classical texts!

Even a single wave here contains array mysteries far exceeding those of the sixth-grade killing array he set up!

"As long as you can cross this sea of ​​formations and reach the other side, you will have passed the first level."

Rosa's deep voice echoed in the air above the array sea before falling completely silent.

"Cross this sea..."

Looking at the raging sea of ​​formations before him, filled with endless killing intent, Chen Fan's lips curled into a rather helpless bitter smile.

"The legacy of this ancient demon is really pushing people to their deaths."

It's important to understand that this sea of ​​formations is so vast that even a late-stage Nascent Soul cultivator, let alone a Void Refinement or Body Integration stage expert, would be instantly annihilated by the endless array patterns if they dared to forcibly traverse it without understanding formations.

The only way is through enlightenment!

Step by step, they deciphered the operating rules of these array patterns, stepping on the array's core to find the gate of life.

"Since there's no way out, we can only take it one step at a time!"

As his thoughts raced, Chen Fan's eyes sharpened, and he sheathed the eleven swords.

As we all know, brute force is useless against formations.

With his hands behind his back, he lightly touched the ground with his toes and steadily stepped onto the edge of the array sea.

"Buzz..."

The moment his foot landed, the patterned seawater beneath his feet reacted instantly.

Several sharp array wind blades silently sliced ​​out from beneath the water's surface, heading straight for Chen Fan's legs.

"Third-grade killing formation, Wind Swirl."

Chen Fan's expression remained unchanged as his divine sense instantly locked onto the spiritual energy nodes of these wind blades. He merely shifted his toes slightly to the left by half an inch.

"Whoosh!"

The wind blades grazed his trouser legs without even damaging the hem of his clothes, and then dissipated in mid-air.

"The first step is to find the gate of life on the left. This formation on the edge is relatively simple."

Chen Fan understood.

The design of this array formation is clearly progressive, gradually moving from simple to extremely difficult.

This is also the ancient demon testing the inheritor's talent in formations and learning ability.

So, Chen Fan started walking slowly through this sea of ​​array formations.

The previous month.

The edge of the array sea is mostly composed of array combinations of grade three to five.

This was not a major challenge for Chen Fan, who had deciphered countless ancient formations and was well-versed in the art of word-fixation.

As he walked, he dispersed his divine sense.

He could discern the trajectory of each formation within a few breaths.

Sometimes, one uses the concept of life and death to find the point of transition between life and death within the formation.

Sometimes, one can use the concept of cause and effect to trace the origin of the formation.

Even when faced with complex, interconnected formations, he only needs to stop and do some deduction to easily deal with them.

During this month, Chen Fan traveled approximately several hundred miles within the array sea.

Despite the churning waves and lurking dangers around him, he strolled leisurely, as if he were taking a walk in his own backyard.

however.

This relaxed situation did not last long.

When Chen Fan crossed an invisible boundary and arrived at the central area of ​​the array sea.

The surrounding environment suddenly underwent a dramatic and drastic change!

"Boom!"

The array-patterned seawater, which had been merely rolling on the surface, suddenly seemed to boil. Countless enormous water columns formed from runes shot into the sky, weaving together in mid-air to create a massive, sky-covering array net.

Chen Fan abruptly stopped, his expression instantly turning extremely serious.

He tried to extend his divine sense, only to find that it was pulverized by the surrounding violent array laws as soon as it left his body less than three feet away!

"The formation level here... has instantly jumped to above the seventh rank!"

Chen Fan was greatly shocked.

A seventh-grade formation is a terrifying existence capable of trapping and killing a Void Refinement stage expert! Moreover, this is not a single seventh-grade formation, but a complex and deadly formation forcibly combined from thousands of incomplete seventh-grade formations according to a pattern he could not comprehend at all!

He tried to take a step forward.
