The bodies of this pair of dragons were extremely huge, with a domineering aura that soared into the sky, hard scales covering the huge body, and the hardness of the claws was comparable to that of a high-grade spiritual weapon.

These two dragons have strong physical defense, and are even immune to many ability attacks.

But even so, their vaunted physical defenses and ability immunity are useless against the basketball-sized [Echo Bug].

The two dragons slammed down, splashing gray dust in the sky.

For a time, the earth shook and the sky was full of dust.

The dragon clan has always been known for its coercion and toughness, and the dragon clan's sound attack secret technique is not weak.

But in the face of this [Phaseless Shadowless Echo Worm], their sound attack secret technique is simple and trivial.

The basketball-sized echo worm, Sen Ran's cold eyes stared at the two giant dragons on the opposite side that were more than sixty meters long, and the small body suddenly had a crazy momentum erupting, and the powerful coercion was dozens of times more powerful and terrifying than the two dragons just now.

The little thing is very discreet!

After the two dragons were blasted down from the air by its sound attack secret technique, it did not come close to these two dragons in the first place. Instead, open your mouth wide again:

"Roaring ......"

"Roaring ......"

......

Two mighty roars of thunder slammed into the ears of the two dragons.

"Poof!"

"Poof!"

The eardrums burst, and blood spurted out of the ears of the two dragons.

At the same time, the consciousness of the two dragons also fell into darkness.

It seemed certain that the two dragons had fainted, and the echoworm body had vanished into thin air. In an instant, it appeared in the sky above the two dragons.

Looking down at the two dragons, [Echo Worm]'s compound eyes showed a hint of disdain humanely.

A dragon of the Dragon Clan's Tribulation Period. They were all despised by this strange worm.

If it is known to outsiders. Absolutely will not believe it.

"Ang ......"

Suddenly. [Echo Worm] made a thunderous sound again.

The heads of the two dragons suddenly exploded as if they were being blasted by a huge thunderclap.

White brains and blood flowed down the dragon's seven orifices.

[Echo Worm] suddenly turned into a phantrum and landed on the head of one of the dragons, enjoying its feast as it pleased.

The two dragons of the Tribulation Period died so much that they couldn't die again!

Having eaten the brains of one of the dragons, [Echo Worm] lifted its asymmetrical head, full of intoxication.

Here, its vigilance has been reduced to a minimum.

But just as it was feasting on the second dragon's brain, the mutation took a steep turn.

The whole space. Suddenly twisted and changed, and a powerful spatial energy enveloped its body, locking it on, making its body instinctively sluggish.

Echo Worm, a trace of horror and doubt flashed in his eyes.

Its speed is fast, that is the law of resonance derived from the law of sound, and it can comprehend a certain law of space. And the stronger its sound laws, the stronger the space laws it comprehends.

But now, a wave of powerful spatial power is coming, and it has not found it. This caused a trace of fear and jealousy to rise in its heart for no reason.

After all, judging from the fluctuations of this wave of spatial capabilities, this is secretly dealing with its enemies. In terms of the control of the laws of space, it is definitely much higher than it.

This also shows that the speed of this secret man is faster than it!

"Roar—"

An ultra-terrifying voice sounded in the nearby space, and the echo worm was ready to shake the space with sound, and then through the law of "resonance", find out the spatial leakage, so as to escape.

With this loud noise, the nearby space suddenly generated waves of invisible energy energy.

A weak position in space suddenly appeared in the [Echo Bug]'s soul sense.

"Ang ......"

Let out a furious roar again, shaking away the spatial pressure on its body, it quickly flashed towards the weak position of space.

As he got closer to the weak space, a flash of joy flashed in [Echo Worm]'s eyes.

But in an instant, there was an incomparable fear in its eyes.

A trace of purple light strangely drilled through the weak part of the space, and exploded at great speed.

"Boom ......"

The power of thunder and lightning slammed into [Echo Worm].

"Whew......"

The echo worm wailed, but did not die. It seems that the energy of this thunderbolt is released just right. If the amount of strength is increased by one point, the echo insect will be seriously injured, and if it is reduced by one point, the echo insect can easily hold on.

This was just the right amount of force to make [Echo Worm]'s body instinctively paralyzed.

If there is no follow-up attack, the paralyzing sensation will disappear within a second at most.

However, one second is enough for Lu Chong, who secretly attacked the Echo Worm, to accomplish a lot of things.

The powerful soul shockwave is also rapidly activated, causing an extremely strong fainting effect on the soul of the [Echo Bug].

At the same time, Lu Zhong mobilized the power of the [Great Silence Extinguishing Pearl] and easily included the [Echo Worm] in the [Great Silence Extinguishing Pearl].

The soul consciousness fell into a deep sleep, and Lu Zhong directly used the supreme secret method to quickly imprint his mark in the soul of the [Echo Worm], refining the [Echo Worm] that could easily kill the dragon into a service worm.

Through the memories of this [Echo Worm], Lu Zhong also found the whereabouts of the other [Echo Worms].

There are not many of these [echo bugs] in number. In the entire Fierce Insect Realm, there are only about one hundred and fifty of them. They all live in a place called [Echo Valley] in the southeast rainforest of [Fierce Insect Realm].

This [Valley of Echoes] is blessed with countless underground caves.

These caves extend in all directions, and the most important thing is that these underground caves are attacked by terrifying [Ghost Hell Yin Wind] from time to time.

Each time the [Hellish Wind of Hell] is together, the [Echo Worm] can absorb a large amount of free mystical energy, helping them to continue to evolve.

However, the strength of [Echo Worms] does not mean that they are strong in their reproductive ability.

Their fertility is far inferior to that of the Atlanteans.

There are more than one hundred and fifty insects [Echo Worm], which is the only number left in the [Atlantis] Small Thousand Generations Realm for tens of millions of years.

A long time ago, there were almost hundreds of millions or even billions of [echo worms] in this small thousand world.

But. Over time. [Echo bugs] also seem to have a fertility problem. It's on the verge of extinction.

"The strength of the Echo Bug is good, but the number of its population is too small. Knowing the memory of [Echo Worm], Lu Chong shook his head secretly.

In fact, in Lu Chong's cognition, although the reproductive ability of [Echo Worm] is not as good as that of other Zerg, it is still easy to do twin births a month and twenty-four births a year.

However, it would take thousands of years for the [Echo Worm] of this small Qianshi realm to give birth to twins. Even now, the number of thousand-year-old twins cannot be maintained.

The Zerg were known for their strong reproduction. This is the most powerful force they have ever had in surviving the battle of countless races.

Once the powerful [biotic] breeding ability disappears, even the most powerful Zerg will be dragged into the long river of history and become the dust of history.

Secretly screaming for these [echo insects], Lu Chong was suddenly stunned, some fragments seemed to flash in his mind, he lost his mind slightly, and muttered: "However, I seem to remember a recipe that seems to improve the reproductive ability of the zerg." Belch...... What are the herbs for this recipe?"

Sensing that these memory fragments flashed, Lu Chong immediately sank down and sensed it seriously.

"Shengxi Pill?Epimedium Immortal Huo, Burning Sun Flame Snake Zhi, Demon Attraction Heart Lotus...... Wait a minute. There are also several main medicinal herbs, I ...... Why don't I remember......" Lu Chong's brows suddenly tangled.

He remembered the name of the elixir that could improve the reproductive abilities of many living beings. Even some of these drugs are well known. However, there were some major medicinal materials in it, but he couldn't think of them.

These memories are all of the plague god Lu Yue!

However, although Lu Chong absorbed a trace of the true spirit of the plague god Lu Yue, this true spirit contained a large amount of Lu Yue's memory, but it was not comprehensive.

Therefore, at this moment, Lu Zhong couldn't think of it at all.

"Forget it, if you can't think of it, you don't want to. Let's take all [Echo Bugs] into custody first......"

Lu Zhong has always been free and easy, since he can't think of it, he won't think about it for the time being.

He believes that the boat will naturally go straight to the bridge!

Besides, he had plenty of time to study the [Birth Pill].

Even if I can't think of this [Breathing Pill] pill all the time, it doesn't matter, there are many alchemy sects in the cultivation realm, and it is okay to find some pills with the same pharmacology from them. Even if the efficacy is much worse, it doesn't matter much. As long as it works. With the power of the [Great Silence Extinguishing Bead] and other magic weapons superimposed on time, it will not be too difficult to allow some living races to recuperate and grow.

Echo Valley is located in a hot and humid rainforest to the southeast.

This rainforest has an extremely poisonous miasma, and it is a sacred place for countless poisonous insects. It is also the graveyard of countless powerful demon beasts.

In this huge rainforest, the true king of the forest is not any powerful beast, but an ubiquitous and extremely large army of zergs.

Black-winged mosquitoes, instantaneous centipedes, fierce ants, poisonous scorpions......

Countless poisonous insects that Lu Chong knows and does not know are distributed here.

In the same way, there are also snakes, poisonous snakes, and poisons.

Don't look at the strongest strength of these poisons, they are not in the tribulation period, but once their poison is touched, even the late Mahayana stage and even the strong people of the scattered immortals will be unlucky.

Because of their poison, sometimes even powerful immortals can be poisoned.

Echo Valley, right in the heart of this rainforest.

Even during the day, the final crystal is filled with a super poisonous miasma, and ordinary people, even if they are three tribulation immortals, may not dare to break into here.

It can be said that here, this is the real [Fierce Insect Realm].

[Atlantis] the top powerhouses from all walks of life may not dare to break into the heart of this rainforest alone.

It can also be said that this is a forbidden place for all the top powerhouses.

There are Jedi in the Barbarian Demon Realm!

[Primal Energy Horizon] also has Jedi!

There is also a place of death in the dark magic world!

And this hot forest rainforest in this [Fierce Insect Realm] is a stronger and more dangerous forbidden place and a dead place.

This place is definitely much more dangerous than any plane in the Realm of the Little Thousand Worlds...... (To be continued......)
