Han Lang and the others didn't walk far away. After passing through an arched cave, the front suddenly became clear...?`c?o?m?

It is a vast underground world, with thick yellow sand filled with skeletons of giant beasts.

None of them were complete corpses, and the corpses of these giant beasts were dismantled and kept falling indiscriminately.

Although the corpses are not complete, it is not difficult to calculate from the scale of these bones that they are all giants when they are alive, and one of the ribs exposed to sand is thousands of meters long.

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

Han Lang was stunned and asked in surprise: "How can I see it?"

Lan Feng approached a corpse, pointed to two arm bones, one long and one short, and said: "Prehistorical civilization pursues the limit, and the dark beast is the best evidence for their pursuit of the limit. The so-called dark beast is actually combining the genes of multiple wild beasts, even star beasts, to achieve the most powerful effect."

"So the bones of dark beasts usually have asymmetric characteristics, just like these two arm bones, one as sharp as a blade, and one finger bone is huge and hard."

"The reason for this is that prehistoric humans installed two arms with different functions on the Dark Beast, which were used to capture, and this sharp arm was penetrated with one knife after being grabbed."

While saying that, Lan Feng also made a demonstration, grabbed a stone with his right hand and gently put everything on it with his left hand.

"Do you understand? What prehistoric civilizations need is not symmetry, but function. Just now you saw a dark beast with two heads, or even three heads. Does such a dark beast conform to biological common sense?"

"Of course not!"

"But why did prehistoric civilization design this way? It is because if the dark beast has two or three heads, it can take into account both front, back, left and right, and can look around in all directions. If the detection function similar to bat creatures is continued to be added to the eye area, it will become a very powerful reconnaissance dark beast...?.?`"

Han Lang nodded slightly, "According to your opinion, these giant beasts are also a kind of dark beast, but why are they underground? But we have never seen them when we were on the ground?"

Lan Feng said: "Maybe it is because genetic modification is too difficult, and the prehistoric civilization has failed. 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 from the side: "This guy is the eldest master of the Blue Sky He family after all. There are not a thousand or eight hundred full-time teachers in the family who have followed him since childhood. I am not surprised that Lan Feng knows more."

Lan Feng refused to comment, shrugged gently, looked at the endless underground sand dunes, and said with a heavy voice: "I have a bad premonition that we may have accidentally approached the gene factory."

Swish ~

Suddenly, Han Lang and Lance both changed their faces.

Every ruin in the gene factory is available, and it is used to synthesize dark beasts. The reason why it is difficult for humans to dig the remains is because these genetic factories exist.

In contrast, the gene factory is a place where dark beasts are produced, so it is full of dangers. No one knows what kind of monsters are guarding there.

Lance asked in a deep voice: "Lan Feng, do you really think so?"

Lan Feng nodded, looked around the endless dark beast corpses and said, "If I was not wrong, these corpses were abandoned here after the failure of the genetic experiment, so we are not too far from the gene factory at this moment...?.?`"

"Analysis from the beginning, Han Lang's extreme behavior caused the Hanging Tower Consortium to fall from the air and smash the ground. Because of the attack of the dark beast, we jumped into the abyss and reached the depths of the underground that no one had ever reached before, and encountered many unexplainable strange phenomena. Based on this, it is inferred that we are not far from the gene factory at this moment, which is well-founded."

"I have read a lot of information about the ruins. Every high-level ruin has gene factories. Usually these genetic factories are hidden very deeply, and now we are at least thousands of kilometers below the ruins, which is already deep enough."

Lance and Han Lang both nodded, and Han Lang said: "It seems that from now on, we must be more careful. Lance, it is still the same rule that you can open the way ahead, but you must 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. If we want to leave, we can only continue to move forward."

Lance focused his head and said seriously: "I understand, leave it to me."

Since accidentally discovering that he is approaching the core secret of the relic of A19, Han Lang and the other three have become much more cautious, and they seem a little depressed when they occasionally talk.

It took three days to walk out of this underground desert where the corpse of the dark beast was abandoned, and Han Lang and his friends came to a beehive-like rock wall.

There are countless caves on the black rock walls, connected to each other, like endless mazes.

......

Three days ago, Han Lang and his team climbed the pool of 6.

A strange man came from somewhere, his whole body was tightly wrapped in linen, with only two black eyes exposed, like an ascetic.

He walked into the water and saw the corpses of the strange fish, which were killed by Han Lang and the others in front of the three.

Shaking his head slightly, the ascetic monk in mahjong left the pool and came to the cemetery of those prehistoric civilized warriors.

Looking around, the cemetery had been messed up by Han Lang and the others. The soldiers' corpses were exposed to the air, and all the skulls were crushed. The solidified crystals were taken out, and even the weapons inserted on the grave as to serve as tombstones were missing.

"Thief! Damn thief!"

The ascetic monk in mahjong shivered in anger and shouted loudly in a hoarse voice.

He suddenly raised his head, his black eyes striking towards the rock dome, and his throat made a sharp and shrill sound.

Ao~~~

Ao~~~

This sound does not sound like it was made by humans, but like the wailing of the devil in hell!

After two hours passed, the rapid footsteps in the darkness approached.

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

They are like velociraptors among dinosaurs, but they are much more ferocious than velociraptors. They are covered with a hard shell as hard as pangolins. Their front claws are sharp like large eagle claws. The legs that support their bodies are thick and powerful. Their mouths crack in arc to both sides, filled with steel serrated fangs.

Swish ~

Thousands of velocity dragons and dark beasts came to the monster in scrub, raised their heads, and the black eyes were filled with cold light, like an army of dark beasts.

Bang ~

The Mai monster jumped up, stood on the back of the strongest dark velociraptor, and raised his head again, making a harsh shout.

Rumble ~

The army of Dark Velociraptors rushed up!

Through the arc-shaped dome, we came to the desert that abandoned the corpses of giant dark beasts.

More dark velociraptors are gathering, and in a short time there are more than 10,000!

Ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao ao a

The Mai Shi continued to make unpleasant and harsh sounds. This dark army roared across the desert, and it was very fast. It would probably take a few hours to catch up with Han Lang and the other three.

“There is a dark smell?”

"Is the Heavenly King here too?"

"But why is the king with humans?"

The weirdo in Mai shook his head and muttered to himself.

Bang ~

He slapped the mount hard, and the strongest dark velociraptor's head hit the monster and screamed.

"Things are very strange, chase me all!" The weird man in Mai waved his big hand and ordered.

The black hands are as thin as a vine and as sharp as a scimitar.

There is no doubt that he is not a human!
