Han Lang and the others didn't walk far, and after passing through an arched cave, the front suddenly opened up.

It's a vast underground world, and the thick yellow sand is covered with giant beast bones.

None of the bones were intact, and the bones of these behemoths were dismantled and left in disarray.

Although the bones are incomplete, it is not difficult to deduce from the scale of these white bones that they were all behemoths when they were alive, and one of the ribs exposed to the sand was actually thousands of meters long.

Lan Feng frowned slightly and said, "These are dark beasts. ”

Han Lang was stunned for a moment, and asked in surprise, "How can you see it?" ”

Lan Feng approached a corpse bone, pointed to two arm bones, one long and one short, and said: "Prehistoric civilizations pursued limits, and the dark beast is the best evidence of their pursuit of the limit, the so-called dark beast is actually a combination of genes of a variety of beasts, and even star beasts, to achieve the most enhanced effect." ”

"So the bones of the Darkbeast are usually asymmetrical, like these two arm bones, one as sharp as a blade, and one with a large and hard finger bone."

"The reason for this is that prehistoric humans installed two different arms for the dark beast, this arm was used to capture, and this sharp arm was pierced by a knife after grabbing."

While speaking, Lan Feng also made a demonstration, grabbing a stone with his right hand and lightly everything on it with his left hand.

"Got it? Prehistoric civilizations don't want symmetry, but function, just now you also saw a dark beast with two heads, or even three heads, is such a dark beast in line with biological common sense? ”

"Of course not!"

"But why did prehistoric civilizations design it that way? This is because if the Dark Beast has two or three heads, it can look out in all directions, and if it continues to add the detection function similar to a bat creature in the eye area, it will become a very powerful reconnaissance dark beast. ”

Han Lang nodded slightly, "According to what you mean, these giant beasts are also a type of dark beast, but why are they underground?" And we have not seen it when we were on earth? ”

Lan Feng said: "Maybe it's because genetic modification is too difficult, the prehistoric civilization has failed, and the failed giant dark beast bones are abandoned here." ”

Han Lang smiled slightly and said, "Lan Feng, you know a lot, no wonder you have so many ideals, it turns out that you know everything." ”

Lance said on the side: "After all, this guy is the eldest young master of the Blue Sky River family, and there are not a thousand or eight hundred full-time teachers in the family who have followed him since he was a child, and I am not surprised that Lan Feng knows more." ”

Lan Feng was noncommittal, shrugged his shoulders slightly, looked at the endless underground sand dunes, and said in a heavy voice: "I have a bad premonition that we may have inadvertently approached the gene factory. ”

Swish~

Suddenly, Han Lang and Lance both changed their faces.

There are all the ruins of the gene factory, which are used to synthesize dark beasts, and the reason why it is difficult for humans to dig up the ruins is because these gene factories exist.

On the other hand, the gene factory is full of dangers because it is a place to produce dark beasts, and no one knows what kind of monsters are guarding it.

Lance was nervous and asked in a deep voice, "Lan Feng, do you really think so?" ”

Lan Feng nodded, looked around at the endless dark beast bones and said, "If I'm not mistaken, these bones were abandoned here after the genetic experiment failed, so we won't be too far away from the gene factory at the moment." ”

"Analyzing from the beginning, Han Lang's aggressive behavior caused the Suspended Tower Consortium to fall from the sky and smash the ground, and because we were attacked by the dark beast, we jumped into the abyss and reached the depths of the underground that no one had reached before, and encountered many unexplained strange phenomena, based on which it is inferred that we are not far from the gene factory at the moment, which is well-founded."

"I've read a lot about the ruins, and every high-level ruin has gene factories in them, and usually these gene factories are very hidden, and we are now located thousands of kilometers below the ruins, which is deep enough."

Lance and Han Lang both nodded, Han Lang said: "It seems that from now on, we have to be more careful, Lance, it's still the old rule that you open the way in front, but you have to leave me a position mark, once there is danger, Lan Feng and I will fully support you." ”

"After all, we are already in this strange and strange underground, and if we want to leave, we can only continue to move forward."

Lance nodded heavily and said seriously: "Understood, leave it to me." ”

Since inadvertently discovering that he had approached the core secret of the A19 ruins, Han Lang and the three of them have become much more cautious, and they seem a little depressed when they occasionally talk.

It took three full days to get out of this underground desert that abandoned the bones of dark beasts, and Han Lang and the others came to a beehive-like rock wall.

There are countless caves on the black rock wall, connected to each other like an endless labyrinth

The waterhole where Han Lang and the others landed three days ago.

Out of nowhere, a strange man came, his whole body tightly wrapped in sackcloth, revealing only two black eyes, like an ascetic.

He walked into the water and saw the corpses of those strange fish, which were killed by Han Lang and them three years ago.

Shaking his head slightly, the dervish in sackcloth left the waterhole and came to the cemetery of those prehistoric civilization warriors.

As far as the eye can see, the cemetery has been thrown into chaos by Han Lang and them, the bones of the soldiers are exposed to the air, the skulls are all crushed, the solidified crystals are taken out, and even the weapons inserted on the grave as tombstones are nowhere to be seen.

"Thief! Damn thief! ”

The ascetic in sackcloth trembled and shouted in a hoarse voice.

I saw him suddenly raise his head, his black eyes rushing towards the rock dome, and his throat made a sharp and poignant sound.

Oh~~~

Oh~~~

The sound was not human at all, but like the wail of the devil in hell!

Two hours had passed, and the sound of hurried footsteps in the darkness had approached.

It was a group of dark beasts, a group of large, terrifying dark beasts!

They were like the velociraptors of dinosaurs, but they were much more ferocious than velociraptors, covered in pangolin-hard shells, two front claws as sharp as large eagle talons, thick and powerful legs that supported their bodies, and their mouths were arced to the sides, filled with fangs like steel jagged teeth.

Swish~

Thousands of velociraptor dark beasts came to the side of the linen-clothed monster, raised their heads, and their black eyes emitted a cold light, like an army of dark beasts.

Syllable~

The Mai Monster leaped to his feet, standing on the back of one of the strongest Dark Velociraptors, and raised his head again with a piercing shout.

Thundered~

An army of dark velociraptors has rushed up!

Walk through the curved dome to the desert where the bones of the giant dark beast have been abandoned.

More Dark Velociraptors are gathering, and in a short period of time there are more than 10,000 of them!

Wow~~~

The Mai monster continued to make ugly and piercing sounds, and this dark army roared across the desert, and the speed was very fast, I am afraid that it would not take a few hours to catch up with Han Lang and the three of them.

"Smell of darkness?"

"Could it be that the King of Heaven is also here?"

"But why is the King of Heaven with humans?"

Mai Weirdo shook his head and muttered to himself.

Syllable~

He slapped his mount hard, and the head of the strongest dark velociraptor smashed into the monster screaming.

"It's weird, give me full speed chase!" The Mai freak commanded with a wave of his big hand.

Black hands, thin as vines, sharp as scimitars.

There is no doubt that he is not human!
