Mortal blood!

Boundless Sea!

A famous sea area in the Wanxing Sea.

It is said that in the Boundless Sea, the sea water is endless.

It is a paradise for monsters.

Not to mention ordinary foundation-building cultivators, even Yuanying cultivators need to be extremely careful when walking here.

Maybe at any time, a transformed monster will suddenly rush out of the sea and take your life with one mouth.

Thinking of this, Lin Fan couldn't help but be very nervous.

As a human cultivator, he came to the Boundless Sea alone, which was like a sheep entering a tiger's mouth.

How to escape from here as soon as possible is the biggest problem facing Lin Fan.

"Squeak!"

The two red flame gold scorpions naturally didn't know this. While screaming at Lin Fan, they pulled Lin Fan with their scorpion claws and walked towards the depths of the island.

"This... Is there something else on the island?"

Lin Fan looked surprised.

After signaling the red flame gold scorpion to lead the way, he also followed vigilantly.

The island was not very large, only a hundred feet.

With Lin Fan's strength, he quickly reached the center of the island.

At this moment, the two red-flame golden scorpions stopped in front of a pile of rocks.

Boom!

The red-flame golden scorpion suddenly opened its mouth and spurted out a ball of hot flames.

The rocks on the ground were immediately washed away by the terrifying fire wave.

A hole that could only accommodate one person and led directly to the bottom of the island appeared in front of Lin Fan.

"Could it be that the sea map was found from here?"

Lin Fan was pleasantly surprised.

Originally, he just wanted the two red-flame golden scorpions to find out if there were any spiritual veins on the island.

Then replenish the spiritual power that had been exhausted and leave as soon as possible.

But he didn't expect that there was a secret entrance on this island.

"Squeak!"

The two red-flame golden scorpions nodded happily.

They signaled Lin Fan to continue to follow them inside.

Lin Fan flipped his palm, took out a fragment of an ancient treasure and activated it secretly, summoned Mu Yan, and asked Mu Yan to hide in the dark, and then followed the two red flame golden scorpions.

Perhaps because of the long time, a thick layer of sea sand accumulated at the entrance of the cave.

Going further in, it became wider and wider.

The stone steps were polished very flat and led directly to the ground.

At this moment, Lin Fan was surprised to find that the deeper he walked into the cave, the richer the spiritual energy of the world around him became.

"The deeper I go, the richer the spiritual energy of the world. Could it be that there is a dark spiritual vein on this small island?"

Lin Fan frowned slightly, but was secretly surprised in his heart.

Dark spiritual veins are also a kind of spiritual veins.

Unlike ordinary spiritual veins, dark spiritual veins are generally hidden deep underground and are very difficult to mine. But the spiritual energy in the dark spiritual veins will seep out through a certain gap. Forming an extremely rich spiritual energy gathering place outside.

This kind of place is regarded as an excellent place for cultivation by countless immortal cultivators because of its rich spiritual energy.

Most importantly, where there are dark spiritual veins, the probability of forming spiritual eyes is very high.

But Lin Fan did not hold any hope for the dark spiritual veins on this island.

First, the area of ​​this island is too small.

Second, although the spiritual energy in the cave is rich, it is also relative to the island outside.

Compared with the real large spiritual veins, the spiritual energy on the island is still much worse.

But for Lin Fan, it is better than nothing.

After about a cup of tea, Lin Fan still did not reach the deepest part.

But at this time, a ray of light came from below.

"This is..."

Lin Fan was surprised again and again.

With a move of his mind, he quickly enveloped the bottom.

He found that there was a natural cave of dozens of acres under the ground, which was seven or eight hundred feet away from him.

Around the cave, there were countless moonstones the size of eggs.

The whole cave was illuminated as bright as day.

The spiritual energy in the cave is so rich that it is almost liquid.

Every plant and tree growing in this natural cave is more verdant and robust than the plants and trees outside under such rich spiritual energy.

"This is the Ancient Spirit Cave!"

Before Lin Fan could figure out everything in front of him, Mu Yan's surprised voice rang in his ears.

The Ancient Spirit Cave!

It is the cave of the ancient immortal cultivators.

Because it is very old, and every time it is discovered, a large number of natural treasures are produced.

Over time, among many immortal cultivators, there is a saying of the Ancient Spirit Cave.

Unexpectedly, Lin Fan was very lucky today.

As soon as he arrived at this island, he encountered such a large and complete Ancient Spirit Cave.

"I think it is almost the same. However, in this Ancient Spirit Cave, every plant and tree is well protected. I think there should be a strong protective formation. If we rush into it rashly, we may encounter unexpected events."

Lin Fan nodded and reminded Mu Yan.

He did not hesitate while speaking.

He pointed at the ancient soul-hiding cave below.

A thick spiritual energy of heaven and earth fell towards the direction of the ancient soul-hiding cave.

Not long after, there was a piercing sound, which startled Lin Fan and Mu Yan, and their expressions changed drastically at the same time.

"Sure enough, there is a powerful protective formation. If we want to enter the depths of the ancient soul-hiding cave, I'm afraid we have to use some other means." Lin Fan said.

Mu Yan smiled slightly.

"Master, you don't have to be so discouraged. I think this protective formation is not bad, but it may not be impossible to break it. Master, don't you have a five-element formation in your hand? If we use this five-element formation to attack the weak points of the protective formation in the ancient spirit cave, we can definitely open a gap." Mu Yan said.

Lin Fan knew nothing about formations.

Hearing what Mu Yan said, he could try his luck.

Nodding, he immediately said: "There are many natural treasures in the ancient spirit cave. Moreover, there is a spirit gathering formation in this ancient spirit cave. If we can open the protective formation and enter the spirit gathering formation. Maybe I can try to form a pill. Even if there is a risk, it is worth it."

With a flip of his hand, Lin Fan took out the five-element formation without hesitation.

After walking forward for a while, Lin Fan did not move forward.

With a wave of his hand, he inserted the flag of the five-element formation directly into the ground.

After filling the spirit stone, he activated the array disk.

Boom!

A terrifying five-element light column fell directly on the protective array below.

But the protective array below was very powerful.

Facing the attack that even the immortal cultivators in the Linking Dan stage dared not resist, the surface of the array light curtain only lit up a faint red light, and completely withstood the attack of the five-element array.

"Really strong. It seems that the owner of this ancient soul-hiding cave is really extraordinary. If so, this ancient soul-hiding cave is definitely worth my anticipation!"

Lin Fan was not discouraged at all, but was full of energy.

Although the protective array in the ancient soul-hiding cave is strong, because no one controls it and it is old, its defense is much weaker than before.

Lin Fan believes that as long as he insists on using the five-element array to attack continuously, he can definitely destroy the protective array outside the ancient soul-hiding cave.

Just like that, it took ten days. When the middle-grade spirit stones in Lin Fan's hand were about to be used up, there was finally a slight cracking sound from the protective formation of the Hidden Spirit Cave.

This made Lin Fan's eyes light up.

"Is this the protective formation of the Hidden Spirit Cave finally destroyed?"
