When the Jie Cha witnessed this scene, his complexion changed suddenly, and his figure flashed like the wind, hidden invisible.

Underneath the altar lies a vast cavern that stretches as far as the eye can see, as if leading to another unknown world.

In the cave, a majestic blue and gray giant tree stands proudly in the center, like an ancient guardian god, and it is the legendary world tree.

Its trunk is towering into the sky, more than 100 zhang high, thick as a city wall, up to dozens of zhang wide, the branches are criss-crossed, dividing into hundreds of branches, and the green leaves are lush and vigorous.

What's even more amazing is that the height of this World Tree is not its limit, the crown at the top of it seems to penetrate the void, and all the branches and leaves are hidden in the endless void, and it is impossible to see the whole picture.

Even so, the scale of this World Tree is already breathtaking, as if it were a masterpiece of nature, full of endless mystery and majesty.

Underneath the World Tree, there are endless circles lined up.

These circles vary in color, and there are as many as thirty-six of them.

Each large array is composed of tens of thousands of formations, intricate, and they are all seventh-level magic arrays, arranged according to the direction of Zhou Tian, like a chessboard between heaven and earth, as if containing infinite mysteries and wisdom.

At this moment, the void below the World Tree fluctuated, and a silver token flashed out.

With the appearance of the token, streams of rich black gas poured out of it, quickly condensing into Su Wu's figure.

Su Wu's eyes swept around, and when he saw the towering World Tree and the thirty-six seventh-level arrays under the tree, he couldn't help but feel a little amazed in his heart.

Although he was not a master of formations, he had a lot of knowledge and quickly saw the mysteries of these formations.

Among these large arrays, there are offensive arrays, defensive arrays, and spirit gathering arrays, all of which exude a faint light at this moment, operating on their own, guarding this mysterious space.

What surprised Su Wu the most was that there seemed to be some kind of mysterious connection between these thirty-six seventh-level magic circles, they were connected to each other, faintly forming an even grander hexagonal magic circle.

This hexagonal circle seems to encompass all the formation changes between heaven and earth, which is mysterious and profound.

"This feeling....Could this hexagonal giant array be the legendary Eight Extreme Array?" Su Wuxin secretly exclaimed.

He couldn't imagine what kind of person with extraordinary talent could perfectly fuse and combine so many magic circles with each other to form such a huge magic circle that was difficult to find.

Su Wu didn't stay too long, and immediately flew towards the center of the big array.

In the process of flying, he continued to emit Dao Dao black qi around his body, and these black qi quickly fell on the magic circle below, and instead of refining the magic circle, it began to rapidly corrode and destroy these seventh-level magic circles.

Although the seventh-level array was powerful, no one urged it at this moment, and a large number of formation patterns were fused by the black qi, and the formation began to be destroyed.

One after another, the great arrays extinguished their light, and the entire underground circle began to tremble violently, as if it was about to collapse.

At the same time, Jiecha has also chased into the underground space.

When he saw that Su Wu was frantically destroying the Great Array, he was immediately furious and shouted, "Stop!" This place is the core of the Three Realms Immortal Boat, and once it is destroyed, the Three Realms Immortal Boat will also collapse! ”

As if he hadn't heard it, Su Wu let out a strange laugh in his mouth, and more black qi emanated from his body, continuing to destroy the other large arrays.

His laughter echoed through the cavern, full of madness and determination.

"How dare you do that!"

Jiecha's face was pale, and his eyes were full of anger.

As soon as he pressed his hands into the void, his palms burst out with brilliant blue light, which seemed to have spirits, and quickly connected with the magic circle on the ground, intertwining into a complex pattern.

The ten fingers of the Boundary Cha fluttered like flying, and the blue light continued to flicker, and the magic circle on the ground seemed to be injected with new vitality, and began to burst out with dazzling light one after another.

These lights are dazzling, like stars falling, reflecting the entire cave as if it were day.

The first to light up were the defensive circles, which emitted a blue and gold light, surging out like ocean waves.

These rays met with the black qi of the cicada released by Su Wu, and although it could not completely block it, it made the corrosion and devouring speed of the black qi significantly slowed down, buying precious time for the follow-up counterattack.

Immediately afterwards, the attack circle was also mobilized by the Jiechayi.

Pieces of fire clouds condensed above the magic circle, as if there was a fire phoenix soaring in it, exuding a blazing breath, thunder and lightning intertwined into a net, flashing dazzling electric light, releasing powerful electric energy, layers of ice and mist spread around the magic circle, cold and biting, as if it could freeze everything.

These attack methods all erupted with powerful power, blasting towards the black qi everywhere and Su Wu himself like a raging storm.

Although the black qi was ferocious, in the face of such a dense attack, it had to retreat step by step, being consumed little by little, and gradually dissipating into the air.

When the world saw this, his heart was at ease.

He knew that this was far from enough, Su Wu's strength was unfathomable, and he had to go all out to really stop the other party.

On the ground, after Su Wu's figures disappeared one after another, Yuan Ming did not leave immediately.

At this moment, he was still undistracted to cross the mana into the tall trunk, and every wisp of mana was carefully transmitted, for fear of disturbing something.

Finally, with his unremitting efforts, the refining process was completed.

On the forbidden wooden pillars, the blue light flickered endlessly, and each rune seemed to be given life, flashing with brilliant brilliance, as if announcing that they had a new owner.

Yuan Ming's hanging heart finally settled steadily at this moment, and he felt the steadfastness he had never felt before.

"That's it."

Xi Hezi's voice sounded in Yuan Ming's sea of knowledge, faintly with a hint of exhaustion.

Then, as if summoned, the tall World Tree slowly floated out of the blue light, gently broke away from the wooden pillar, and returned to Yuan Ming's dantian.

"Thank you Xi and Zi Daoyou." Yuan Ming thanked him from the bottom of his heart.

He knew that without Xi Hezi's help, this forbidden wooden pillar would probably have been subdued by Su Wu long ago, and all his efforts would be in vain.

After the World Tree left, the Forbidden Wooden Pillar also returned to its original state, and the array patterns on it were still shining and shining, and the brilliance did not diminish in the slightest.

Yuan Ming's palm gently stroked the wooden pillar, and suddenly, a warm current came from the wooden pillar and poured into his sea of knowledge.

It was a flood of forbidden information, pouring uncontrollably into his soul, deeply engraved in it like a brand.

There is too much forbidden information, and with Yuan Ming's current cultivation, he was a little unbearable for a while, and his pupils were out of focus for a while.

It took him a long time to recover, and an irrepressible look of surprise appeared on his face.

The information that poured into his mind was the prohibition situation within the Three Realms Immortal Boat.

Within the Three Realms Immortal Boat, there were actually thirty-six seventh-level magic arrays, which were the number of Tiangang, and they were hidden in the depths of the altar.

In addition to these seventh-level magic circles, there were also seventy-two sixth-level magic circles and three hundred and sixty-five fifth-level magic circles, which were distributed farther away, guarding this immortal boat together.

These magic circles are arranged according to the direction of Zhou Tian, and they are linked with spiritual veins with each other, and under the synergy, the power is amazing.

With only thirty-six seventh-level magic circles operating at the same time, they could reach the power of the legendary eighth-level array.

It's just that Yuan Ming's cultivation is still shallow, and even if he refines the forbidden wooden pillar, he can't urge so many large arrays.

Despite this, Yuan Ming was not disappointed, but showed joy.

In the process of communicating the prohibition, he memorized the formation diagrams of the two seventh-level magic circles, which were already extremely precious treasures for him.

Yuan Ming is now a sixth-level formation mage, and he has learned a few more seventh-level formations, which has a great effect on improving his formation cultivation.

It was a pity that time was pressed at the moment, and he couldn't carefully probe the other seventh-level magic circles.

There is a space movement prohibition in the entire silver tower space, Yuan Ming urged the wooden pillar, and his body flickered, and he disappeared from the place.

In the next moment, he appeared in subterranean space.

The moment he appeared, Yuan Ming saw at a glance Su Wu, who was constantly releasing black qi to destroy the Great Array, and the Boundary Cha who was following closely behind.

His eyes twinkled, and he didn't choose to chase after him to help or do anything else.

He knew that there was still a big gap between his strength and Su Wu, and rushing forward would only increase the danger.

As a result, Yuan Ming once again urged the forbidden wooden pillar, and under the flickering of his figure, under the gaze of Su Wuhe Jiecha, he appeared next to the huge World Tree.

With a bit of jealousy and anger in his eyes, the former began to release black qi at an accelerated pace, while the latter did not show any special change in expression when he saw Yuan Ming.

Yuan Ming's palm stroked the tree, and the roots of the World Tree emerged from his palm, trying to take root in the giant tree.

This giant tree contained an incomparably large amount of World Tree Qi, far beyond what his World Tree could match, and if he could refine it all, his World Tree would be able to ascend to the sky in one step.

After a few breaths, Yuan Ming showed helplessness and withdrew his palm.

There was a similar seal within this giant tree, and he was unable to absorb the wood qi in it.

Although it was a little regrettable, this attempt was not in vain, just now, he immediately discovered one thing, the huge shadow that his World Tree had communicated with before was the World Tree in front of him.

There was a huge space inside this tree, which stored a huge amount of heaven and earth spiritual power, forming a huge ocean of spiritual power, which was better than any spiritual vein Yuan Ming had ever seen.

The World Tree is the ancestor of all trees, much better than the Immortal Tree, and its roots can directly take root in the void turbulence and absorb the spiritual power in it.

The Three Realms Immortal Boat has been parked here for an unknown number of years, and it is only then that such a huge amount of heaven and earth spiritual power has been accumulated in the giant tree, and all the magic circles in the immortal boat rely on the spiritual power provided by the World Tree to operate.

Yuan Ming's World Tree had just been condensed, and it had not yet shown a similar effect.
