Li Yan, who was a hundred miles away, felt as if the whole world here was suddenly shaking violently.

Then, the originally calm sea under his feet began to shake violently, as if it was having a cramp. Without warning, it started to stir up huge waves like crazy.

At this moment, the scene of roaring waves and tsunami and strong winds appeared on the sea surface.

The waves were rising high and heading straight into the sky. The mask where Li Yan was was hit by the waves, which were like spears or mountains, stabbing or hitting.

After the light shield glowed with patches of white light, it blocked them one by one, but the sea below seemed to be even more angry, as if aroused with boundless ferocity, and became more and more violent.

The island in front also made a loud rumble, but it did not collapse.

Standing within the light shield, Li Yan could see the thorny ball with red light all over its body, which was only slightly delayed at the entrance of the hole.

The next moment, with a devastating force, the chaotic forces at the entrance of the cave were scattered in all directions!

Then, he plunged into the entrance of the cave, making a loud rumbling sound as he continued to go away.

With such fierce power, Li Yan could imagine how terrifying the power of the spiked ball with red light all over its body was.

Master Lan concentrated the power of his formation on one point, and then all of it exploded in the cave.

Therefore, although there are mountains and tsunamis all around, that's all.

Such great power is due to Master Lan using his own formation and borrowing the formation set up by the old sect master and others, combining the two into one and bursting out.

This is also the result of Master Lan’s continuous research over the years.

Moreover, she also had to consider using the original formation while trying her best not to destroy the formation set up by the old sect leader.

Lest once it fails, the grand formation set up by the old sect master will disappear completely, and if you want to come back here next time, it will be as difficult as climbing to the sky.

As soon as the ball of light entered the cave, it cut through all the obstacles and rushed inwards. Wherever it passed, a normal space was cleared, allowing those chaotic forces to disappear.

Master Lan and Elder Hao in the air, after blocking the light shock wave at the entrance of the cave, the mana in their hands was rolling like a tide, and they were injected into the triangle formation on the ground below.

Elder Hao's mana was divided into three streams, directed at the three sharp corners of the formation. At the same time, the spiritual energy between heaven and earth was absorbed by the original formation and continuously injected into the three sharp corners.

Master Lan's mana is injected into the center of the triangle, pulling the huge power in the triangle formation, and continuously shooting forward along the white light beam.

Just like this, the top of the white light pillar, with the spiked ball all over its body glowing red, rushed towards the cave like breaking waves, dissolving all the power in the cave.

The formation itself can only produce red spiked balls that can break through the ban, but it needs a majestic force to push it, which requires the help of a top powerhouse like Elder Hao.

At this time, the power of the soul has no effect. Only his heaven-destroying magic power, coupled with the infusion of heaven and earth spiritual energy, can sweep all the way.

After years of comprehensive consideration, Master Lan used himself as the eye of the formation to continuously communicate with the forces at both ends and constantly stimulate the formation.

The two men's mana surged, but the expressions on their faces became more and more solemn.

Because, although the red-light thorn ball in the cave that was cutting through thorns and thorns was powered by Elder Hao's seemingly endless mana, the ball continued to shrink as it continued to move forward.

The two of them could clearly sense the size of the ball through the advancement of their magic power. In just fifteen breaths, the red light spike ball had shrunk to more than forty feet, consuming more than half of the forbidden power.

But at this time, the red-light thorn ball has gone out for more than a hundred miles, and it is still moving forward, but the front is still the same. The entrance of the cave has not been seen yet, and it is not known how long the tunnel is.

After another five breaths, the red light thorn ball had shrunk to more than twenty feet, and its speed began to slow down. The expressions of the two of them became obviously nervous.

They knew the formation this time, so it was considered a success!

But they didn't know how long the cave was, so they could only arrange the forbidden formation to a size that could support it at present.

The maximum power of support.

But at this time, they still feel that their future is far away and they don't know how deep it is.

After another three breaths, a layer of dense sweat oozed out on their foreheads. This formation was created by integrating the strongest resources of the sect, but the passage ahead has still not been opened...

If you fail this time and try to gather these refining materials next time, you don't know how many years or months it will take, or even how difficult it is to gather them together.

There were some materials in this formation, but they were never found again. This may indicate that some of the formation materials should no longer be in the "Earth Realm".

After two more breaths.

"boom!"

Although the two of them were still exerting their magic power, there was a loud noise coming from under their feet.

The triangular formation made a roar, and in an instant, it collapsed into rays of radiating white light.

"No, the power of the formation has been exhausted. Let's go in quickly!"

Master Lan's body shook violently in the air with this explosion.

She first let out a muffled groan, then with her magic power running, she forcibly suppressed the violent surge of breath coming from her body, and immediately said to Elder Hao.

As she spoke, her whole body turned into a rainbow, and she quickly rushed in towards the entrance of the cave below. Elder Hao followed closely...

In the cave, there are still many arcs of various colors remaining on the entire cave wall, which are flashing rapidly and making a series of harsh crackling sounds.

The two of them ignored this at all, just swaying, and soon penetrated more than 300 miles into the cave, and then suddenly stopped.

At this time, in front of them, various colors of light appeared again, intertwining and flashing. It was a chaotic and incomparable force.

Just like the entrance to the cave before, they formed a curtain of intertwined and dancing light.

However, these light curtains are still different from before. As they dance and interweave, they actually have a tendency to slowly advance towards the entrance of the cave again.

Master Lan's expression also changed drastically when he saw it.

She immediately waved her sleeves repeatedly, and a formation flag appeared in front of her, and she quickly performed the magic formula at the same time.

"What's going on?"

Elder Hao asked in a low voice.

"This means that the cave has not been completely opened and the normal rules of the world cannot be communicated with the outside world. The current situation here is like the roots of an existing tree!"

Master Lan answered quickly.

She knew that what Elder Hao was asking was not about breaking the ban on the formation, but about why the ban that had been broken could still be regenerated.

According to their previous thoughts, as long as the ban here is broken, this place should be like a formation, and the broken ban will naturally disappear.

When things got here, even if they still couldn't get through the cave, for them, they had actually succeeded in part.

First, it shows that this formation is indeed effective, and there is no problem with the direction of breaking the ban in Zhenhun Palace.

Second, although they were not completely successful this time, they already had a direction and continued to search for materials to refine this formation.

Even if the power of the subsequent formation is weaker, the difficulty of breaking the barrier backward next time will be much reduced.

Maybe even after going deep, the entrance to the other end may not be far away anymore?

But the situation in front of them was different from what they imagined. Those chaotic forces spread out again, preparing to fill the entire cave again.

Master Lan’s answer was also very concise. It was because he failed to cut off its roots and failed to form normal rules with the outside world.

Master Lan replied, her hands moving faster, and the formation in front of her was already arranged in an instant.

Then soon, the chaotic forces that began to spread again came into contact with the formation.

Together.

"Bang bang bang..."

Loud noises came from the ground in front, the cave roof, and the cave wall.

Then bursts of smoke and dazzling light erupted from these places.

That was the formation flag that Master Lan entered. Because the formation could not withstand the spreading power, the formation was forcibly overwhelmed in a very short period of time.

"I'll go in and take a look!"

Elder Hao's eyes flashed with a sharp look.

At this moment, he wanted to know whether the current light curtain was approaching the other end of the cave. If he could get through, he might be able to cut off the source of these strange powers from the other end of the cave.

The sect was working so hard, if he was knocked back to his original form soon, how could he be willing to fall short? At this time, he couldn't care less about taking risks.

He just informed Master Lan, but it was not a negotiation.

Just as he was speaking, a yellow light flashed outside his body, and a furry thing suddenly appeared, like the fur of some kind of monster.

Then, Elder Hao's figure was like lightning, and he immediately shot into the light curtain.

Master Lan looked at all this, although there was anxiety and worry in his eyes, he also knew that Elder Hao and Elder Tang had entered the cave light curtain more than once before when they were trapped.

Therefore, Elder Hao still has a certain understanding of this place, and he may be able to escape unscathed.

But only five breaths later, a figure shot out from the light curtain in front, and then a burning smell wafted out and went straight into the person's brain.

Elder Hao's body was revealed in thick green smoke.

"Cough cough cough... No, after dozens of miles, there is still a continuous chaotic force... cough cough cough"

Elder Hao pulled off the layer of fur on his body and looked at the large scorch on it, a flash of physical pain in his eyes.

Then, with the surge of mana in his hand, the green smoke immediately dissipated, and he put the object away casually. After hearing this, Master Lan also showed a look of disappointment.

While the two were talking, their bodies had already retreated again at the same time. Master Lan continued to use formations one after another, but still failed to work.

So in front of them, it was like setting off firecrackers during the New Year, and the sound of explosions never stopped.

Master Lan's face became more and more ugly. In fact, after she used the first blocking formation and was instantly overwhelmed, she already knew that she could not stop it.
To be continued...
