The northern islands, the bottom of the fountain of immortality.

Bright red corpse cockroaches poured out like a tide.

Li Su seemed to have stabbed a hornet's nest, a large number of insects actually blocked the spring, and the flame-swallowing butterflies were beaten and left behind a corpse, seeing this, Li Su knew that he had to do it.

The magic sword in his hand was waved, and countless sword qi flew out.

The corpse worm turned into a giant lan, and was split into pieces by the sword qi.

The pure demonic energy attached to the Seven-Star Blood Demon Sword immediately killed the insect body after it was contaminated with the corpse cockroach.

Countless beetle shells fluttered and fell, and then countless corpse roaches followed one after another, engulfing the corpses of the insect swarm in front of them, and countless new insects were born and rushed forward......

The most difficult part of fighting demon insects is here, and the corpses of insects after death can be used as nutrients.

If the strange insect can adapt and evolve quickly, then it is really not something that ordinary monks can deal with!

Han Li's Gold Devouring Worm was also very powerful, especially restraining ordinary metallic spiritual creatures, but the cultivation speed of the Gold Devouring Worm was too slow, and it took many years for a group to mature.

And these corpse insects in front of them do not have as long a maturity period as gold eating insects, and coming out of a corpse means that the corpse insects are fully mature.

Moreover, the more insects gather, the more powerful they will be in battle.

"Go!"

Li Su kept killing corpse cockroaches.

But the insects in front of me seem to be boundless.

After killing for a while, Li Su was impatient and cast the 'Yama Golden Body'.

Countless evil qi surged towards Li Su's body, turning into an illusory Hundred Ghost Floating Slaughter magic robe.

The vestment hung down from mid-air, countless grimaces were painted on it, and the evil qi surged on the surface of the robe, and the corpse cockroach wanted to attack the vestment, but the evil qi on it killed the consciousness one by one.

Countless corpse cockroaches slipped from the outer layer of the evil qi magic robe, and Li Su stared at the corpse tide and pierced deeper.

"Rustle!"

The attack of the outer layer also obscured Li Su's vision.

Even the divine sense can't penetrate the thick insect walls layer by layer, so it can only make Li Su know some directions in front of him!

"Click!"

The gravel in front of him shook.

Li Su looked ahead, and the bigger insect nest seemed to be in front of him.

The corpse cockroach sleeping at the bottom of the spring woke up from the shock, and then frantically attacked Li Su, who was wrapped in a ball in front of him......

The evil spirit continued to kill the corpse cockroach, but a new one pounced.

So much so that Li Su's body was wrapped in a layer of insect shells, and he was almost moving forward with this insect shell.

There were twists and turns on the way, and the stone walls turned into blue crystals.

"These blue crystals?"

Li Su took a crystal from the stone wall.

The blue crystal is extremely hard, and there is a bug sealed inside, which is the corpse cockroach that is madly attacking him.

"Is this the material for nesting?"

Looking at the insect that was sealed in the crystal, the tentacles moved slightly, as if they were about to wake up.

Li Su let the blue crystal disintegrate and ran out of a corpse cockroach.

"Squeak!"

The worm, which had awakened from the crystal, did not seem to have figured out what was going on.

After waking up from his slumber, he subconsciously began to attack indiscriminately, and Li Su's palm became the best target......

Looking at the corpse cockroach that was attacking the palm of his hand, Li Su also realized that something was wrong here!

"This is a hive crystal!"

Li Su casually broke a large piece of blue crystal.

Obviously, after discovering that there was no shelter, these corpse insects were wrapped in these blue crystals tens of thousands of years ago, and then they sealed themselves in the crystals and slept until 10,000 years later.

"I don't know if I can find the mother?"

Corpse cockroaches are a kind of strange insects, but the ones Li Su killed were just some miscellaneous soldiers.

Completely incapable of showing fertility!

Only when the female insect corpse cockroach is found, can this strange insect be raised.

However, the intelligence of the female insect is generally relatively high, and Li Su broke in with such a killing ring, and the female insect must have escaped from other places early under the cover of other corpse insects.

Li Su thought about it and didn't force it.

Although the power of the strange insect is strong, it also takes years to cultivate.

For example, the fire-swallowing butterfly is also one of the strange insects, and Li Su also cultivated it for a while.

It's a pity that the growth and development of the Fire-Swallowing Butterfly requires too much high-quality spiritual fire, and Li Su gradually slackened off after that, and the Fire-Swallowing Butterfly raised was given to those close to him......

The same is certainly true for corpse roaches.

If you want to grow, you must devour the corpse of a powerful demon beast.

And the corpse of a powerful demon beast is very valuable in itself, and it can be used to refine weapons and alchemy, so why feed it to insects?

The same is true of Han Li's Gold Devouring Worm.

The ore that the Gold Eater grows and devours is simply terrifying......

"Raising insects is too resource-intensive!"

Li Su discovered that the blue ore was a seal for the ancient corpse cockroach.

They no longer continue to attack these ores, but choose the path with the least movement.

It's a pity that even if Li Su doesn't attack these corpse cockroaches, this group of little guys who wake up from sleep always like to bump into Li Su's evil magic clothes, and die at Li Su's feet one by one.

"Shhh

The blue hedron in front of him flew away.

Li Su also dodged and handed the magic sword forward.

"Rub!"

The blade of the sword pierced in half.

A huge corpse cockroach was revealed.

It turned out that the mountains were shaking just now, and it was this giant worm that was waking up.

The demonic qi on Li Su's magic sword was rolling, and after pouring into the corpse cockroach's body, all vitality was destroyed......

"It's really demonic!"

The giant insect howled, and was eroded to death by demonic energy.

Seeing this, Li Su did not stop, and continued to hit the bottom.

The distance under your feet is getting farther and farther away.

There are more and more strange corpse insects encountered.

Some of these corpse cockroaches gathered together, simulating an ancient beast.

Even Li Su didn't feel it was an eye-opener!

And in this process, even if Li Su was full of combat power, he was accidentally injured......

Especially those ancient beasts, their methods are all strange.

Even if the corpse cockroach can only simulate a part of its power, it will also make Li Su, who has never seen it, suffer a big loss.

"Wow!"

Li Su spat out a mouthful of black blood.

Just now, there is a demon beast that looks like a mirror.

took a shot at Li Su's body, and almost didn't shine Li Su to death directly.

Of course, after the mirror demon beast took a look at Li Su, it itself shattered and disintegrated on the spot......

"It's too dangerous!"

There was still the rustling sound of insects squeezing around.

Li Su stopped, recuperated his breath, and swallowed the healing pill.

Walking here, Li Su is probably the first person in the human world, and he has a hunch that there must be a big guy under his feet!

With this point of view in mind, Li Su continued to dive.

The insects seemed to have turned into running water, leaving a corpse on Li Su's body.

Only the appearance of some huge corpse cockroaches with extraordinary powers can make Li Su pause......

Maintaining this situation, Li Su dived for an hour.

The surrounding stone walls are no longer the usual black-brown color, but have turned into completely blue crystals.

This made Li Su feel like he was making a hole in the hive!

So far, I haven't encountered a female worm along the way, so I just think it's a pity, but I think it's normal......

Just when Li Su was about to go numb, the blue ore under his feet shattered.

Li Su did not destroy the ores under his feet, but these ores crumbled by themselves!

"What?"

Li Su's body

Plummeting.

Immediately, a yellow mist shrouded his eyes.

Li Su felt the weightlessness of his body and tried to adjust his body posture and fly.

But when Li Su was about to fly into the air, he found that all the aura was invalid!

"Not good!"

Li Su saw this, and his heart was not good.

The big hole dug under his feet should be a place to seal the spirit.

Generally speaking, this kind of prohibition is almost ineffective for the Avatar Monk, and it is broken immediately......

It's like the prohibition of the Scarlet Forbidden Land is to salute it!

The so-called foundation cannot be built inward.

In fact, you can go in whenever you want!

It's just that it's more troublesome not to enter on the day of the Scarlet Forbidden Land.

"Woo Woo ......"

When he couldn't fly, Li Su fell all the way down.

"Bang!"

Until a bump.

Li Su's shoulder hit the ground hard.

A huge crater appeared in front of Li Su's eyes.

"Karma, click......"

When landing at high speed, the blue crystal arm forms a crack.

"Shhh

Li Su crawled out of the hole.

I found that the top of my head and my feet around me were all wrapped in blue crystals.

This should be a cavity underneath!

After calculating the time it took Li Su to dig a hole and go down, it took Li Su at least an hour to come here.

In this way, this place is at least tens of thousands of feet above the surface!

"Hiss!"

Li Su gasped.

I don't know how thick the surface of the earth is, and I haven't seen underground magma after digging tens of thousands of feet.

"Light!"

Li Su switched the auspicious light of the colorful deer.

At the same time, the 'auspicious' aura of the divine beast is added, and there is Li Su's own divine source qi......

Li Su walked towards the center of the cave.

But I saw that there were blue crystals all around, but there were no corpse insects in these crystals.

Only those blue crystals mixed with the dirt of the stone wall will release a large number of corpse cockroaches to attack everything frantically when touched.

The blue crystals turned into bamboo-like pillars in the underground cavity, and the various strange-shaped crystal stone carvings around it also looked beautiful.

When Li Su arrived in the center of the cavity, he found that above his head was a crystal stalagmite as large as a hill.

A stalagmite made of blue crystals hangs upside down from a stone wall.

"Tick, tick!"

There are constant drips of liquid in the stalagmites.

In the center of the cavity, a small pool of water gathered.

Li Su was very curious, what is the liquid dripping out of the stalagmite of the blue spar?

"Is it a 10,000-year-old stalactite liquid?"

Li Su thought about it and shook his head.

Stalactite liquid is a treasure of heaven and earth, how can there be such a big lake!

That's right, it's a lake!

Li Su walked to the lake, and there were blue spars at his feet.

Therefore, the colorless lake also looks like blue, and Li Su took a jade bowl and took a little water from the lake......

This water is in a jade bowl, and it turns into a spar when it is shaken!

"Huh?"

Li Suqu poked his finger in the jade bowl.

The hedron immediately cracked.

The debris slowly dissipated as if there was no residue at all.

"I don't know what this thing is?" Li Su was a little curious: "These blue crystals seem to have the ability to seal, and the corpse cockroach has been sealed for tens of thousands of years, and when it comes out, it will be alive......

Could it be that the crystal walls in this underground cavity are all made of these liquids?

Li Su tried to fly up to the upside-down stalagmites to see what secreted these blue crystals!

It's a pity that the strange ban on flying here, Li Su is also difficult to fly onto the bamboo shoots.

Li Su took out the 'Fountain of Youth' from his bosom and the water in the lake that would turn into blue crystals......

After comparing them, Li Su found that the two had similar ingredients.

It's just that the yin qi and corpse qi in the Fountain of Immortality don't have the richness that will turn into blue crystals!

"It's like life and death coming together in a drop of water!"

That's right, Li Su discovered that these waters, which will turn into blue crystals, are a kind of strange spiritual water with powerful vitality.

But Li Su wanted to try to drink the water, but Lingjue sent a terrifying warning telling him not to do it!

"No, what kind of water is this?"

Li Su looked at the water of this lake with some curiosity.

It can turn into blue crystals and seal a group of corpse cockroaches for 10,000 years, and there is a powerful life force, but at the same time, it cannot be drunk by people......

Tsk, is it poisonous?

can be Li Su's physique at this time, and the ten strange poisons can also resist for a while.

Is this water more poisonous than the ten strange poisons?

"Forget it, take some!"

Filled some of the water from the lake with the gourd that he carried.

Unfortunately, after the magic gourd filled the water, the water immediately began to condense into blue crystals.

The gourd, which can fit into a lake, continues to crack and crumble.

"Bang!"

The gourd exploded at once.

The blue crystals wrapped the gourd fragments in it and plunged to the bottom of the lake.

"I can't pretend to be ......."

Li Su shook his head and didn't care anymore.

After pondering for a moment, he was ready to climb the blue crystal bamboo shoot hanging upside down.

"Drink!"

Li Su clenched his fists.

Make a hole in the crystal wall and put your hand into the hole.

In this way, one hole, one step at a time, all the way up and up, it took three hours to reach the root of a bamboo shoot the size of a hill.

Li Su circled around this root, and didn't find anything suspicious!

However, Li Su discovered that there seemed to be a strange thing sealed in the huge bamboo shoots on the top of the rock wall......

"What the hell?"

Li Su grabbed the stone wall with one hand and began to hammer the stalagmites with the other.

"Bang! Bang! Bang!"

Hedrons splashed everywhere under the fists.

However, Li Su continued to punch and punch until the blue crystal the size of the hill was smashed.

Li Su seemed to hear the sound of the mirror shattering, and then the crystal wall that Li Su grabbed after making a hole was no longer stable, as if there was a chain reaction collapse on the ice......

"Pong! Table tennis! Pong!"

I don't know that the stalagmites that Li Su knocked shattered, and the crystals of the entire cave collapsed.

Seeing this, Li Su huddled his head and curled up, dodging all the flying stones.

"Scratch!"

The crystals all fell to the bottom of the lake.

Li Su is no exception.

After Li Su fell into the lake, he wanted to look for the foreign object in the stalagmite, but found that he couldn't swim......

Suddenly, a description flashed in Li Su's mind: "Those who are weak in water can't cross with a feather!"

"Gollum! Gollum!"

A god-shifting monk actually drowned.

If it weren't for Li Su, who couldn't feel a little buoyancy, he would have been spitting bubbles and sinking to the bottom.

Li Su himself couldn't believe this kind of thing!

However, if this lake is the legendary 'weak water', then Li Su's drowning is really normal, this is the so-called weak water that the gods can float through!

No wonder Li Su's spiritual sense reminded him that it was poisonous when he wanted to drink it just now!

After being drowned in weak water, Li Su struggled to swim away.

It's a pity that the weak water doesn't have a trace of buoyancy, and it is difficult for Li Su to move forward with his hands and legs, so he can only hold his breath and wait until he reaches the bottom of the lake, and then try

Get out of the bottom of the lake.

If you're unlucky, maybe like these corpse cockroaches, they will be sealed by blue crystals, and then they will be discovered ten thousand years later!

"Knock ......"

Li Su stepped on the bottom of the lake after a pause.

The bottom of the lake was dark and he couldn't see the environment clearly, and Li Su tried to walk forward.

It's a pity that at the bottom of the weak water, although he can walk, Li Su actually has a sense of suffocation.

The method of internal circulation and breathing was supposed to suffocate under the terrifying weak water!

"Gollum!"

Li Su couldn't help but feel dizzy.

He knew it wasn't a lack of oxygen.

Even if the Avatar Monk lacks oxygen, he will definitely not die, Li Su feels that it should be weak water, which is constantly seeping into his skin, waiting for it to seep into his internal organs, he should also crystallize, and then be sealed at the bottom of the lake for tens of thousands of years......

"Go, you have to leave."

Li Su no longer tried to find something, but prepared to walk towards the shore.

It's a pity that the speed of weak water penetration is getting faster and faster, and Li Su can feel the rigidity of his thinking, and even see a little crystal chips on his hands and feet......

"It's over!"

Li Su felt a little desperate in his heart.

Not only can you not fly above the weak water, but even your mana is imprisoned.

can only walk to the shore at the speed of ordinary people, Li Su will definitely be sealed in the lake in advance!

"What should I do?"

Just as Li Su was about to give up, a burning sensation came from his arm.

"Hmm!"

Li Su looked down.

It turned out that under the cover of the sleeves, a silver dragon gate tattoo was emitting a strange light, echoing a place at the bottom of the lake......

"It's something sealed in a blue crystal stalagmite!"

Li Su walked quickly towards the glowing place at the bottom of the lake.

After getting closer, Li Su's eyes flashed, and the surrounding environment had changed dramatically, and the world had changed!
