Underneath the lotus-shaped volcanic fault crater is a very peculiar topography that resembles a 'U' shape that stretches infinitely at both ends. This topography guarantees that the sea cannot submerge this volcano. This terrain is large in the middle and slender on both sides. On one side is an elongated inlet, and in the middle is a submerged, the water pressure of the submersible area is balanced by the external seawater pressure, the water surface height of the submersion area is low, and on the other side of the submersible area is an elongated outlet.

Chen Feng and the others swam slowly along the current to the outlet, and saw the wonderful scenery and strange fish in this fiery red rock crystal pool.

Chen Feng touched the warm rock wall and said with a light smile: "Hehe, the volcano should erupt from time to time, and the stones on the rock wall have been washed into the hardest and purest crystals, maybe there will be countless diamonds or crystals and the like." ”

The outlet on the other side of the submerged area is very long, about dozens of kilometers long, anyway, I don't know where I swam to the water, but Chen Feng can be sure that this place should not be far from Tiechuan Sea.

The strange fish in the water are ferocious, but they are not very large. Chen Feng was a little hungry, hooked his claws, grabbed a thorny fish that seemed to have been fried into pink flowers by an oil pot, and regardless of whether it was poisonous or not, he opened his huge mouth and squeaked and bit down, and the delicious flesh and blood dripped into the water with the saliva at the corner of his mouth.

Countless fish began to surround them, and the smell of blood tempted their appetites. Chen Feng smiled coldly: "Peaches, it's appetizer time, eat as much as you like, haha." ”

Although these fish have been deep in the submarine volcanic rivers for a long time, and their evolution is very strange, there are still grades on the top of their heads, and the grades are about 50, which are suitable for making dietary supplements.

In this way, on the journey out of the river, Chen Feng and the others were eating at the same time, eating all the strange creatures they encountered along the way, including fish, corals, and even underwater zergs.

These creatures are low-grade, but all of them are very ugly-looking, enough to make people vomit overnight at a glance. But Chen Feng didn't care, just imagine them as stinky tofu before eating them, to be honest, maybe it was because they had been soaked in high temperature water for a long time, and the creatures here tasted particularly tough, as if they were chewing kraft candy.

The speed of the water flow was slow, Chen Feng and they swam quickly in three steps and one step, and soon they came to a place similar to a sharp downhill, after the water flowed downhill, I believe that there must be another world below.

Chen Feng grabbed the convex corners of the hard rock wall, stretched out his head and looked at it twice, the fiery red rocks and snow-white waves, because the take-off degree of the river impact was relatively large, so they covered most of the perspective.

Chen Feng said in a loud voice: "Peach, gunboat, we jumped down to find the ultimate secret of evolution (Chen Feng made it up), this road will not turn back no matter what, do you have anything else to say when you jump?" ”

Chen Feng's muscles tensed, and he looked at them with bloody eyes, in fact, he had already made up his mind to push them no matter what they said.

The gunboat glanced at him, bared its teeth, and jumped down with a plop.

"Dry, crisp enough, I like it."

Chen Feng excitedly rushed to the sky, the insect body hung in the air, and suddenly heard Peach's innocent laughter: "Brother, the blood on your head has run away, it has run..."

"What?" Chen Feng only felt that his eyes were dark, and the insect body had already fallen straight away like a meteor cannonball. On the surface of the tumbling water, he saw the blood hole in the main brain...

The crimson rock wall reflected the three huge and terrifying figures, they crouched in this underground cage like the three giant demon kings, hissing and roaring as if they were reprimanding the injustice of the heavens, and the brutal momentum of catharsis made the entire demon cave realize that they were very unhappy, very unhappy.

"Thief, I grass your ancestor, haha, you think you can escape my living cage, you think you can regain control of the swarm, the swarm has given birth to the will of the swarm, and they will crush you under the enslavement of the will."

After Chen Feng declared his manic tyrant's will, he began to calm down again, calm like a muffled thunder, and even the usual big peach did not dare to look at his murderous and vicious gaze.

"Let's go."

Peaches stretched out her little wings and rubbed her eyes, just now it was lying on the belly of the gunboat and sleeping soundly. He pushed the gunboat, which was snoring violently, and then flapped his wings and flew up and followed Chen Feng towards the depths of the crimson rock wall.

After a brief lull, Chen Feng's words broke the silence and eerie surroundings, awakening Peaches and the gunboat from sleepwalking, and he left the red waterfall hanging high on the volcanic wall first, and climbed along the edge of the volcanic wall.

The interior of this volcano has stone walls that rotate all the way to the bottom of the endless fiery red, some are wide and some are narrow, but in Chen Feng's eyes, these stone walls have obvious traces of digging, but even so, you have to walk on them carefully. Above his head, a high, red waterfall caught all the water by a kind of stone trough that led into the depths of the volcano, with a faint sound of steam stinging.

If it weren't for these large stone troughs, Chen Feng would have fallen into the volcanic lava and turned into a cloud of gas.

If you don't die in a great calamity, you will have a blessing in the future. On the surface, the irascible Chen Feng seemed to have calmed down, but deep down, his anger was like the inside of this seemingly calm volcano, showing signs of eruption at any time.

It must have been the gunboat's lightning bolt striking its own worm body through the current, causing a blood hook spasm, and the thief was able to escape from the exoskeleton of the main brain. Where can it escape to this vast sea?

In this underground volcano, Chen Feng's will to rule the insect swarm can still be connected to the fungus mother, and the fungus mother replied that there was no trace of the thief, and even the tyrant guardian insect was calmly stopped in the middle of the deep sea and remained motionless.

The unknown whereabouts of the thief are a great hidden danger.

The purity and simplicity of the tyrant's will make Chen Feng not do any other nonsense, his will must be completely concentrated on one point, that is, the ultimate secret of the early evolution matrix, so he must calm down, as a tyrant, calm anger is also a violent aesthetics.

With sparks of anger flashing in his blood-red eyes, he walked out with his tail wriggling, any words that came out of his mouth stained with blood and coldness: "This volcanic nest has been dug up by hand, and non-primitive ruins can be found here. ”

After seeing the true face of the Demon Cave, he would not be surprised that there were traces of artificial excavation in this ancient volcano, all the traces here were definitely not carved out by primitive insects and beasts, let alone natural.

He sniffed violently and said lightly, "There's a very smelly smell here, which upsets me." He looked out and saw a flat dam sticking out of the volcanic rock wall, and the platform above it was smooth, as if it was a transfer station.

Chen Feng's heart was immediately attracted by this, and he temporarily forgot about the thief's escape. This shijie is really a secret everywhere, and he has to study this so-called geocentric ruin.

The insect jumped and stood on this flat dam. Chen Feng found that the perspective of this flat dam is particularly good. They can look down on the entire inner nest of the volcano. When I looked down, I saw a lot of strange runes depicted on the ground of Pingba, and many ugly creatures that could stand on their hind legs, as if they had crawled out of hell, around the edge of a square stone, slightly sticking out their tongues and hissing and roaring.

"What are these?"

Peaches' crisp voice floated into Chen Feng's ears like a ghost, and he realized that Peaches had already stood on his main brain at some point, and immersed his entire body in the blood hole that had been hidden by thieves in the main brain.

It shook its little wings twice, licked the blood on it, and said with a smile: "Brother, your brain is so warm, I will squat in it in the future to be a human face for you, hehe..."

Chen Feng's steely insect body trembled slightly, and under the reflection of volcanic red, it was completely messy...
