Mortal blood!

Boom!

The ear-piercing thunder roared.

The void was shaking violently at this moment.

An indescribable sense of terror and crisis suddenly erupted from the depths of Lin Fan's heart.

The huge thunder crystal beasts had already rushed towards Lin Fan frantically.

With their mouths opened, a series of terrifying thunder and lightning rule forces slashed down on Lin Fan.

Not long after, Lin Fan was submerged by the terrifying thunder and lightning rule forces.

"Husband!"

Lan Lan, who had already reached the shore of the Blood Source Lake, shouted.

But Lin Fan did not respond.

Only a terrifying rule force fluctuation erupted from the thunder and lightning rule force.

About three or five breaths later, the terrifying thunder and lightning rule force was destroyed by an extremely powerful fist attack.

Seeing this, Lan Lan was delighted.

"Husband, how are you?"

"Don't worry, Lan'er, I'm fine for now. However, I have attracted all the Thunder Crystal Beasts in the entire Blood Source Lake. If I want to leave, I'm afraid I can only kill them all."

Lin Fan smiled bitterly.

The Thunder Crystal Beasts are too warlike.

And they like to gather in groups.

Now, Lin Fan has just killed a Thunder Crystal Beast in the middle stage of the Golden Immortal Realm.

This time, he really poked the Thunder Crystal Beast's nest.

It caused countless Thunder Crystal Beasts to attack Lin Fan frantically.

Boom!

The harsh thunder sound rang out again around Lin Fan.

Even though Lin Fan's physical strength is comparable to that of the late Golden Immortal Realm, facing this terrifying thunder tribulation attack, Lin Fan's scalp was numb.

In the end, there were too many Thunder Crystal Beasts surrounding him.

It was not easy for Lin Fan to escape.

"With so many Thunder Crystal Beasts, I can't kill them all by myself. If so, I have to think of other ways!"

Lin Fan frowned slightly.

As he spoke, a red flame slowly emerged from in front of Lin Fan.

On the red fire lotus, a terrifying flame suddenly erupted.

In an instant, the temperature within a radius of tens of thousands of miles rose suddenly.

At the same time, the immortal power in Lin Fan's body also fell madly into the red fire lotus.

Whoosh!

The red flame rose rapidly above Lin Fan's head.

At this moment, its size reached an astonishing size of hundreds of feet.

The red flame light burned dozens of nearby thunder crystal beasts into ashes in an instant.

Seeing this, the other thunder crystal beasts in the Blood Source Lake all showed a strong fear.

But seeing their companions being killed so easily by Lin Fan, all the thunder crystal beasts became more and more irritable.

After a few dozen breaths of silence, the thunder crystal beasts roared to the sky.

One by one, the thunder crystal beasts of the Golden Immortal rushed to the front.

After that, there were countless thunder crystal beasts in the Golden Immortal realm.

Behind them were the Thunder Crystal Beasts of the Heavenly Immortal Realm.

Three different batches of Thunder Crystal Beasts simultaneously attacked Lin Fan.

Those terrifying Thunder Tribulation Rule Powers seemed to destroy the void in an instant.

Seeing this, Lin Fan's expression changed drastically.

While pushing the World-Destroying Red Lotus to its limit, he also pushed the Immortal Blood to its limit with a thought.

Boom!

A sharp thunderous sound rang out.

Even though the World-Destroying Red Lotus was now erupting with the terrifying Fire Rule Power, it burned dozens of Thunder Crystal Beasts of the Golden Immortal Realm that rushed towards Lin Fan into ashes.

However, the number of Thunder Crystal Beasts that rushed over later was still very large.

All of a sudden, Lin Fan was submerged in the Thunder Crystal Beast Tide.

This made Lan Lan, who was standing on the shore, tremble with fear.

However, Lin Fan, who was under the attack of the Thunder Crystal Beast, did not panic.

With a thought, all kinds of attacks were pushed to the limit.

Huh!

The power of the rules of life and death was running wildly.

In a moment, almost all the vitality in the Thunder Crystal Beast quickly turned into death.

At the same time, Lin Fan activated all the Iron-Eating Ants.

An airtight barrier was formed around Lin Fan.

Whenever a Thunder Crystal Beast approached, these Iron-Eating Ants would rush up and bite wildly without fear of death.

The Thunder Crystal Beast, which was as big as a hill, could not stop the attack of the Iron-Eating Ants.

In a moment, it was completely devoured by the Iron-Eating Ants.

At this moment, Lin Fan's three Yuanying incarnations were also activated to the extreme by Lin Fan.

At this moment, Lin Fan almost used all his means.

Although the Thunder Crystal Beast's attack was still very fierce.

But at this moment, Lin Fan vaguely mastered the rhythm of the battle.

Boom!

The power of the Thunder Tribulation Rule in the distance was still sending out terrifying attack power.

However, Lin Fan stood in the air with a calm expression.

Beside him, three Yuanying incarnations kept urging various attacks to resist the thunder crystal beast's thunder tribulation rule power attack.

Outside, there was a barrier formed by the iron-eating ant colony.

The outermost was the killing zone formed by the world-destroying red lotus.

Lin Fan, who was in the blood source lake, exuded a terrifying aura all over his body.

His cold eyes stared at the thunder crystal beast in the distance.

Suddenly!

Taking advantage of the thunder crystal beast group's unpreparedness, Lin Fan snorted coldly.

The majestic divine thought impact suddenly spread like a tide.

Those thunder crystal beasts who frantically urged the thunder tribulation rule power to attack Lin Fan suddenly trembled all over.

The horrible thunder tribulation rule power that was activated was greatly reduced at this moment.

Taking this opportunity, a terrifying fire rule power erupted from the world-destroying red lotus.

In just a moment, hundreds of thunder crystal beasts were burned to ashes.

At the same time, the power of the rules of life and death, the iron-eating ant colony and other attack methods are also making great achievements at this moment.

In one fell swoop, most of the Thunder Crystal Beast's attacks were neutralized.

This made Lin Fan's eyes light up when he was in the Blood Origin Lake.

"It turns out that the impact of spiritual thoughts formed by the consciousness thorns is the best way to deal with the thunder crystal beast."

"However, the impact of the Divine Consciousness Sting alone is not enough. If there are no other powerful attack methods, being trapped among so many Thunder Crystal Beasts is still a death!"

Having said this, Lin Fan smiled lightly.

The next moment, the second divine consciousness stab attack was activated by him again.

Buzz!

Countless thunder crystal beasts that rushed over were once again struck by Lin Fan's spiritual thoughts.

The attack speed was greatly reduced.

Taking advantage of this opportunity, Lin Fan followed suit.

Another group of thunder crystal beasts were killed.

However, after taking action this time, Lin Fan had no intention of continuing to take action.

His eyes swept over the outermost group of iron-eating ants.

Lin Fan was surprised to find that the iron-eating ants that had devoured the bodies of many Thunder Crystal Beasts had become more and more resistant to the power of the Thunder Tribulation Rules.

Moreover, a faint golden light emerged from every iron-eating ant.

It seems to be the power of thunder attribute rules.

"This...could it be that the iron-eating ants mutated after devouring the thunder crystal beast?"

Lin Fan looked overjoyed.

The attack power of the iron-eating ant colony is very terrifying.

Unfortunately, their attack methods are somewhat single.

If it is a swarm of iron-eating ants, blessed by the power of the thunder attribute rules all over its body, it will definitely be able to exert more powerful attack power in future battles.

Thinking of this, Lin Fan thought and released three Nascent Soul incarnations to slow down his attack speed.

Let the iron-devouring ant swarm he controls devour more thunder crystal beasts.

Wow!

Led by the Iron-eating Ant King, the iron-eating ants rushed towards a Thunder Crystal Beast in the Golden Immortal Realm in front of them.

In an instant, the thunder crystal beast was swallowed up, and not even the dregs were left.

At this moment, the number of thunder crystal beasts in the Blood Source Lake was greatly reduced.

There was nothing that could stop Lin Fan from leaving.

But Lin Fan had no intention of leaving.

He only waited for him to control the iron-devouring ant swarm and kill most of the thunder crystal beasts in Blood Source Lake.

Before the iron-devouring ants could rush over, the remaining Thunder Crystal Beasts plunged into the Blood Source Lake and disappeared completely.

This left Lin Fan speechless for a while.

"Escaped?"

Lin Fan frowned.

His eyes swept over the iron-eating ants.

It was shockingly discovered that from the Iron-eating Ant King to every Iron-eating Ant, there was a strong power of thunder-attribute rules.

From the looks of it, the mutation of the iron-eating ant colony is already a certainty.

In addition, there are many iron-eating ants, which look lazy at the moment.

Lin Fan, who was well aware of the characteristics of iron-eating ants, understood instantly.

These lazy-looking iron-eating ants may be evolving again.

"Every time the iron-eating ant evolves, not only will its strength improve a lot, but it will also become more ferocious."

"This time, the iron-eating ants have devoured so many thunder crystal beasts, and they still have a certain amount of thunder attribute power in their bodies."

"When they are completely transformed, their combat effectiveness will be even more powerful."

"Is this a blessing in disguise?"

Lin Fan smiled secretly.

In a flash, he came directly to the shore of Blood Source Lake.

Seeing the frightened Lan Lan looking at him and smiling charmingly, Lin Fan immediately smiled and said: "Lan'er, I've frightened you."

"Husband, you are really powerful. I just thought that you alone would not be able to withstand so many thunder crystal beasts."

"I didn't expect that the thunder crystal beasts were almost exterminated by you."

Lin Fan smiled lightly.

"Lan'er, if the thunder crystal beasts don't provoke me, I won't bother to pay attention to them. Now that they have attacked me, I can't sit still and wait for death!"

As he spoke, Lin Fan turned his palm and took out a positioning disk.

After injecting immortal power, it is quickly activated.

Unfortunately, there was no response on the positioning disk.

This made Lin Fan frown.

"The ancestors should be far away from us, and there is no response on the positioning disk. If so, I will try to contact fellow Daoist Bai and Fairy Chen."

Lin Fan flipped his palm and changed the positioning plate again.

After being injected with immortal power, there was still no response on the positioning plate.

This made Lin Fan frown.

"I didn't expect that the area of ​​the underground palace is so large. If this is a complete world, there is no problem."

Lin Fan looked around curiously, sighing with emotion.

Seeing this, Lan Lan nodded seriously.

"My husband, you are right. The underground palace is very vast, and the Immortal Burial Tomb is in the core area of ​​the underground palace. No matter which direction you go from, you only need to walk forward in one direction to reach the Immortal Burial Tomb."

"If that's the case, let's take a short break, why not move on."

Lin Fan nodded.

Taking this opportunity, he quickly took out some elixirs and began to meditate and refine them to replenish the consumed immortal power.

In the battle just now, Lin Fan actually didn't consume much.

However, there were many dangers in the underground palace, and Lin Fan did not dare to be careless.

Only by maintaining abundant immortal power at all times can we have a certain degree of self-protection when encountering danger.

There was nothing to say for a while, and he only waited for Lin Fan to practice for most of the day, and after the immortal power in his body was completely restored to its original state, he and Lan Lan continued to move towards the Immortal Burial Tomb.

However, before they had gone far, they were blocked by the vast blue sea.
