Immortality, starting from the heaven and earth.

"Could this place really be the cave dwelling of the Great Thunder Ancestor?"

In the void, Lin Yi looked at the distant, sprawling palaces, a hint of horror in his eyes.

His purpose in coming to the Purple Origin Thunder Sea was to obtain the Purple Marrow Thunder Essence Liquid, thereby preparing himself to enter the Nirvana Realm.

But the current development is happening too fast.

Before even reaching the location of the Purple Marrow Thunder Essence Liquid, they encountered a rare thunder eye storm and eventually ended up directly inside this secret realm.

Thinking of the secret realm, Lin Yi's gaze unconsciously drifted to the Purple Origin Immortal Lord not far away.

Honestly.

Even though this Purple Origin Immortal Lord brought them to this secret realm, Lin Yi still harbored some doubts about him.

When we were at Thunder Bluff, we had just mentioned the secret realm when we encountered the Eye of Thunder halfway through our journey, and that's how we ended up here.

Everything seemed too coincidental.

"Fellow Daoist Lin, now is not the time to be distracted."

Just then, Thunder Immortal Lord's voice suddenly came from the side.

Almost the instant the sound faded, a deafening roar of thunder exploded forth.

"Roar!"

Lin Yi looked in the direction of the sound and saw a group of thunder beasts roaring and rushing in from all directions.

"Boom!"

Before these thunder beasts could even get close, rolling thunder roared and struck the four of them first.

"Boom!"

At the same time, Thunder Immortal Lord formed hand seals.

Accompanied by the sound of rolling thunder, terrifying bolts of lightning shot out from his hands.

In the blink of an eye, these thunderous forces struck the charging thunder beasts first.

"Oh!"

Both were formed from the power of thunder, but Thunder Immortal Lord truly lived up to his reputation as a Taiyi Golden Immortal who primarily cultivated the laws of thunder.

Amidst the flashing lightning, each strike of the thunderbolt emanating from his hand could easily tear a thunder beast to shreds.

Even so, the expressions on everyone's faces remained unchanged.

Too much.

There were too many of these thunder beasts, and they seemed inexhaustible.

Even though it was destroyed a moment ago, it was re-formed as the rolling lightning in the void gathered.

"These thunder beasts are simply condensed thunder power, not thunder spirits contained in the thunder sea outside."

Thunder Immortal Lord quickly noticed the difference and hurriedly reminded him.

“There must be a key point in this formation. Otherwise, these thunder beasts could not have been born so quickly.”

"Then let's search, search little by little."

Gao Boxian responded loudly.

His body shone with golden light, like a golden meteor, transforming into a golden rainbow in the void and crashing straight into the thunder beast before him.

"Oh!"

In a flash, he suddenly appeared on the back of a thunder tiger and, from above, delivered a powerful punch.

"Oh!"

The immense force exploded on Lei Hu's body in an instant, causing the latter to be torn to pieces.

"Great! These thunder beasts may not have any spirit, but they're just right for me."

As he spoke, Gao Boxianjun rampaged through the thunder beast horde, and with each punch and kick, one thunder beast after another exploded.

During this process, the thunder beasts retaliated with their most ferocious attacks, but their sharp claws only left shallow white marks on his body, which disappeared in an instant.

"I would like to trouble you three fellow Daoists to hold off these thunder beasts for now. I will find the location of the core formation here as soon as possible."

At this moment, Immortal Lord Ziyuan spoke loudly.

Almost the instant his words fell, Lin Yi saw a flash of golden light in his hand, and one after another, purple immortal mirrors rushed out in all directions as his magic incantation was performed.

In a short while, eight purple fairy mirrors appeared outside him.

Upon seeing this, Lin Yi's gaze shifted, and a clear light representing his Eye of Insight flashed between his eyes.

"Indeed, this woman's understanding of this place far surpasses what she had previously revealed to us."

Lin Yi keenly noticed that the moment the purple immortal mirror condensed into an array, the void around the woman distorted at a speed visible to the naked eye.

It seemed to be affected by the formation, but in reality, it gradually merged with the void in front of it.

"Fellow Daoist Lin, the promise between us still stands."

At this moment, Lin Yi's eyes flickered, and he heard a message from Immortal Lord Ziyuan.

"Never mind, getting the Purple Marrow Thunder Essence Liquid is the priority."

Upon hearing this, Lin Yi nodded.

"go with!"

A flash of celestial light appeared in his hand, and the Twelve Heavenly Swords Diagram emerged.

"Life and death, yin and yang, thunder and lightning. Unleash!"

As he spoke, sword techniques flew out from Lin Yi's hands, and three different immortal swords based on different laws flew out from the array diagram.

"Swish swish swish swish."

In an instant, three different sword energies based on different laws condensed at a speed visible to the naked eye.

In the blink of an eye, a huge sword formation condensed in mid-air.

"The Great Luo Three Absolute Sword Formation, break!"

The next moment, Lin Yi let out a low shout and immediately used the Great Luo Sword Technique that he had obtained from Xiang Feiyu.

Wherever his sword pointed, countless sword energies of law surged forth like a tidal wave, roaring towards the thunder beasts that were surging in from all directions.

"Bang, bang, bang"

As the two came into contact, the thunder beasts visibly shattered into pieces under the onslaught of the sword energy of the law.

The scene was terrifying. The Thunder Beasts were being cleared out like wheat being harvested, at a visible speed in just a few breaths.

"it is good."

Upon seeing this, Thunder Immortal Lord's eyes lit up.

"As expected of a sword formation containing the essence of the Great Luo, it is indeed so powerful."

Lin Yi is incredibly efficient.

Gao's strength alone surpassed that of him and Gao Bo Xianjun combined.

Although neither of them used their full strength, judging from Lin Yi's relaxed expression, they were clearly not at their limit either.

Something's not right!

At this moment, Immortal Lord Gao Bo suddenly shouted, smashed the head of a thunder beast with a punch, and retreated rapidly to the side of the three.

Perhaps it was because the Thunder Beasts were destroyed too quickly, or perhaps it was because he had been fighting them in close combat, but he was deeply moved.

"Unlike the thunder beasts that initially reformed after their destruction, the lightning power they possessed seemed to begin to diminish the moment they dissipated after their deaths."

As they spoke, the three exchanged glances and then looked at Immortal Lord Ziyuan.

But as the eight purple mirrors around him shimmered, they somehow coalesced into a single purple vertical pupil.

Suddenly, a burst of purple light erupted from his pupils, transforming into a purple beam that shot straight toward the distant, sprawling palaces in the void.

This purple light did not contain any powerful energy, but wherever it shone, the shattered thunder beasts turned into countless tiny sparks of lightning, drifting towards the largest palace in the distance.

In the blink of an eye, all the lightning bolts vanished.

"This is?"

Lin Yi's gaze sharpened slightly, and he spoke slowly.

"These thunder beasts were originally formed from the thunder power that emanated from that palace."

I used the Purple Source Immortal Light as a guide to temporarily restore order, but we must find a way to overcome this obstacle as soon as possible.

Ziyuan Immortal Lord slowly spoke.

"What do you mean, fellow Daoist?"

Thunder Immortal Lord's expression changed.

"These temporarily returned thunderous powers have reappeared?"

“That’s right, so we should take advantage of this time and get into the palace as soon as possible.”

The voice of the Purple Source Immortal Lord came, and her gaze also fell on the palace, a complicated look flashing in her eyes.

"Taihao Leizu set up this formation precisely to test those who enter it."

"If we only focus on slaughter, the power of that palace will eventually resurface to an unstoppable level." "This place is an infinite void, and it contains a spatial power that can affect our divine sense. Finding a way through this place won't be easy."

Immortal Lord Gao Bo frowned.

"Since you are able to temporarily guide the lightning power after the Thunder Beast's destruction, do you have a way to get through this place?"

Immortal Lord Ziyuan pondered for a moment, then suddenly looked at Lin Yi.

"Does Fellow Daoist Lin have any insights?"

Lin Yi did not answer immediately.

While activating the sword formation to continue annihilating the charging thunder beasts, he surveyed his surroundings, observed the distant palace, and recalled the records about the Great Thunder Ancestor in the Creation Immortal King's inheritance.

"The core of the formation!"

He spoke slowly.

"Since the Thunder Beast is not a real living being, but part of the formation, it must have a core."

"The core of the formation?"

Thunder Immortal Lord's eyes lit up.

"Does Fellow Daoist mean that among these thunder beasts, one is the core of the formation?"

"It's not necessarily among the Thunder Beasts."

Lin Yi shook his head.

His gaze passed over the horde of thunder beasts and landed on the floating palaces.

"If I'm not mistaken, the core of the formation should be in that palace."

He was not pointing to the largest main hall, but to an inconspicuous small hall next to it.

The small hall was dimly lit, a stark contrast to the main hall's brilliance, and would almost be overlooked if one did not look closely.

"That one?"

"Immortal Lord Gao Bo asked in confusion."

Why that one?

"Because it's too conspicuous."

Lin Yi said calmly.

"The main hall is too dazzling and constantly absorbs scattered lightning. Anyone would be attracted to it at first glance."

But precisely because of this, it's easy to overlook the real key points.

He paused, then continued.

"And have you noticed that although these thunder beasts are surging in from all directions, there is one direction in which no thunder beasts have ever appeared?"

Everyone followed his gaze.

really.

Not a single thunder beast approached the dimly lit little hall within a radius of a hundred feet.

"go!"

Immortal Lord Ziyuan made a decisive decision.

The four of them attacked together, fending off the thunder beasts' onslaught while rapidly approaching the small hall.

The closer they got to the small hall, the more ferocious the Thunder Beast's attacks became.

Bolts of lightning struck from all directions, seemingly intent on tearing them apart. Their power far surpassed that of the lightning beasts they had encountered before.

"puff!"

At this moment, Thunder Immortal Lord suddenly spat out a mouthful of blood, and cracks appeared on his immortal light shield. He looked astonished.

"This place seems capable of devouring my Thunder Laws."

"Ok?"

Upon hearing this, Immortal Lord Gao Bo let out a low roar, his body blazing with golden light, and he unleashed a punch at the oncoming rolling thunder beast.

At the same time, Lin Yi's gaze sharpened, and with his right hand forming a sword gesture, countless sword energies of law converged into a colossal sword that cleaved towards the front.

"Shh!"

Wherever the sword light passed, the thunder beasts along the way were all wiped out.

"Now's the time!"

As they spoke, the four of them simultaneously rushed into the small hall, which was within a hundred feet of it.

Almost the instant they stepped inside, the Thunder Beasts that had been relentlessly pursuing the four of them abruptly stopped.

They stood a hundred feet away, their eyes, filled with lightning, fixed on the four of them, but dared not take another step forward.

"really."

Lin Yi was certain.

Within this hundred-zhang radius lies the safe zone of the formation.

"Fellow Daoist Lin is indeed a man of great hidden talent."

"Immortal Lord Ziyuan said softly, a strange light flashing in his eyes."

"Fellow Daoist Ziyuan, you flatter me."

Lin Yi said calmly.

"It was just a fluke. Besides, if you hadn't been able to bring back the lightning power that gave birth to the Thunder Beast, we probably wouldn't have been able to get here."

As he spoke, Lin Yi's gaze fell upon the small hall.

It is called a small hall, but that is only in comparison to other palaces.

In fact, this hall is so large that it inspires awe.

Upon closer inspection, the small hall, though dimly lit, exudes an ancient and weathered aura.

The palace doors were tightly shut, and while they appeared unremarkable without any runes, there was a faint lightning pattern on them.

"This door."

Thunder Immortal Lord stepped forward and placed his hand on the door.

"what?"

He let out a soft "hmm".

"This door has no restrictions?"

"wrong."

Immortal Lord Gao Bo also stepped forward to try it.

"There are indeed no restrictions, but... it can't be pushed?"

His physical strength was so formidable that even a slight sliver of space remained unmoved by his push.

Lin Yi stepped forward and placed his hand on the door.

He closed his eyes and probed the door with his divine sense, but it was like a stone sinking into the ocean; he could not sense any movement.

"Fellow Daoist Ziyuan, do you know how to open this door?"

Since this woman's master is a disciple of Taihao Leizu, and can temporarily calm and restore the thunder power of the thunder beast.

Even if you don't know every detail about this place, you should still know how to open the door.

"I can try, but I can't guarantee it will work."

Seeing the three people looking at him, Immortal Lord Ziyuan pondered for a moment before arriving at the entrance of the main hall.

As his hands moved, a series of intricate magic spells were unleashed.

Finally, a drop of crimson immortal blood was forced out from the fingertip of the Purple Source Immortal Lord, and in an instant, it merged with the immortal light condensed by the immortal technique.

As the immortal light flowed, Lin Yi saw the immortal blood on his fingertip transform into a blood seal in mid-air, and fly straight toward the lightning patterns on the palace gate.

"Buzz!"

In an instant, the lightning patterns shone brightly and spread rapidly in all directions like a spider web.

In the blink of an eye, it instantly covered the entire door.

"Boom!"

Just then, the door, which had remained completely still, suddenly shook violently and began to slowly open to the left and right with a muffled sound.

"The door is open!"

Seeing this, everyone was delighted, and even Lin Yi couldn't help but take another look at Immortal Lord Ziyuan.

Disciple by name.

"If he were truly just a nominal disciple, why would he need to use the Blood Seal!"

Lin Yi thought to himself.
