Entrance to the underground base.

"Roar——!"

With a creepy howl, a dark green mutant species resembling a dwarf was sliced into pieces by the sharp sword, and the mutilated limbs struggled and bounced like madness on the ground, struggling to reglue and put them back together.

Through the dark red limb section, you can see the muscles and internal organs that are squirming wildly, and the thin purple-red flesh membrane quickly forms a covering on the section, so that almost no blood flows out.

Song Xuemei next to her looked pale and frightened, she was sure that if the body of this mutant species was spliced together as it was, in less than five minutes, it would return to the state it had not been injured in, which was enough to easily kill the terrifying existence of a twelfth-level evolutionary.

The rot-clawed lizardmen are nightmarish species deep in the ruins, and their ferocity is still higher than that of the three-headed mutant mastiff king.

It is terrifying, not only because of its extreme strength, but also because it has intelligence that is not inferior to that of human beings, and has a unique language and writing, social structure and hierarchy. If there is an analogy, it should be similar to the African tribes before the Holocaust.

It can be said that the rot-clawed lizardmen are a newly intelligent species born on this planet after the catastrophe, and they are theoretically qualified to compete with human civilization for the dominance of the planet.

Thankfully, they are not easy to reproduce, their population size is quite limited, and they live in a high-radiation environment, so they can only be seen in the depths of the ruins.

Seeing those struggling remnants, Qin Feng certainly wouldn't give it a chance to recover, and swept through the light, collecting all the corpses of mutant species on the ground into the dimensional space of the starship.

"It's okay, just keep following me."

Qin Feng smiled at the girl with delicate facial features beside him, and said warmly.

Song Xuemei nodded obediently, her beautiful big eyes were shining, and there was nothing but worship in her eyes when she looked at him.

This terrifying species, which used to exist only in textbooks, is now alive in front of him, and he has been killed by this man who doesn't seem to be a few years older than himself, so what terrifying level of his strength has reached?

At least within the Xiao family, there is no master who can kill the rot-clawed lizard man alone, unless a number of top powerhouses work together and with the help of many advanced equipment.

"This mutant organism is very valuable, and it is said to be a key raw material for refining and synthesizing anti-aging agents." On the way, Song Xuemei whispered.

"Then let's catch a few more later." Qin Feng said disapprerovingly.

The one just now has already been disassembled and absorbed by the starship, and the return is 1200 origins. However, before entering the underground base, he improved his melee combat ability and perception domain ability to the tenth order, and for this reason, the 1620 origin was consumed.

This is something that can't be helped, otherwise, once you face the siege of multiple rot-clawed lizardmen, or other powerful mutant species, even if you have the cultivation of the peak of true immortals, you will have to be more than lucky, not to mention that there is a rookie girl by your side.

The darkness of the underground is even more dangerous than the surface, and the most terrifying mutated species inhabit this dark environment all year round.

Passing through the lead-gray alloy giant gate with a height of more than ten meters, there is a spacious and deep passage inside, and the empty air is full of dead and dangerous atmosphere.

Song Xuemei looked at the small digital display on the back of her hand, the radiation value was always high, she took out a few pills from her tactical backpack and took them, and then stepped forward to hold Qin Feng's hand.

Qin Feng let her hold her, and occasionally chatted with her to relieve the girl's overly nervous emotions.

A few hundred meters away, the second alloy gate appeared, the portal was not completely closed, and it could be clearly seen that the thickness of the alloy door was not less than thirty centimeters, which was enough to easily resist all conventional weapons attacks except nuclear bombs.

Before entering the door, Qin Feng took out a high-explosive grenade and threw it in, and then pulled the girl aside to avoid it.

The deafening explosion reverberated in this underground space, and more than a dozen high-level mutant species roared and rushed out, and they were immediately imprisoned together, and they all died under the sword qi.

When did my sister find such a powerful man?

Seeing that long and vigorous figure advancing and retreating freely in the mutant species group, still looking like she still had spare strength, the shock in Song Xuemei's heart could no longer be described in words.

As the two of them went deeper, they passed through one portal after another, and the passages inside became more and more spacious, and more and more forks appeared, extending in all directions, which showed that the scale of this underground base in the old era was beyond imagination, and it was already a veritable underground city.

From time to time, all kinds of mutant species rushed out without warning, launching fierce attacks on the outsiders who rushed in, and they were all killed by Qin Feng.

Fortunately, the number of mutated creatures here is not very large, if it is as many as tens of thousands like the surface, Qin Feng can only retreat.

The fire and fighting outside should have come to an end, and how much strength is left for the team that can win in the end to enter the underground base, Qin Feng doesn't care very much, those people will die in his hands sooner or later.

After more than half an hour, the two of them successfully entered the central laboratory area of the base.

After decades of silence, the space here still looks clean, the aisles are full of anti-slip patterns of the times, and on both sides of the aisles are rows of huge vertical culture tanks, shaped like giant cylinders five meters high and two meters in diameter, through the thick transparent bulkheads, you can clearly see that they are filled with different colors of liquid.

Of course, most of the tanks are empty, with only a few traces of water remaining. Only a few tanks contain a liquid of medicine, which is soaked in the corpses of some unknown mutant species.

"It's all good stuff."

Qin Feng only glanced at it, and he understood that the value of these mutant species was extremely high, and they were not inferior to the three-headed mutant mastiff king, rot-clawed lizardman, and the like that he had hunted.

It can be seen that when the apocalyptic catastrophe of that year came, this base was still operating normally, and it lasted for a considerable time, otherwise it would not be possible to collect these precious mutant species.

There is nothing to say, take them all away, Qin Feng will not think about leaving them to the people who come in later.

I don't know when, an invisible coercion enveloped the surrounding space, the indifference and majesty that was high up and overlooking all living beings, making Song Xuemei tremble, her face pale, and almost unsteady on her feet. It was the instinctive reaction of a creature when confronted with a powerful predator.

Qin Feng didn't feel anything, and pulled the girl over to wrap her waist, and the realm that belonged to the True Immortal opened up, offsetting the huge pressure she was under.

A moment later, in the core area of the laboratory, in a large pool with an area of hundreds of square meters, Qin Feng saw a rather large unknown creature's body, or rather...... It's a partial body.

The surface of the pool was sealed with a thick alloy fence, and the pool was filled with a reddish potion, and the bubbles on the surface of the water were tumbling and the mist was steaming, emitting a very pungent smell, and the body looked like the thick arthropods of a giant python or a giant octopus.

The body of the unknown creature was apparently still alive, twisting and wriggling despite being soaked in the pool for an unknown number of years, and the majesty of the condensed substance emanated from it.

"Very powerful life ......"

Qin Feng silently estimated that if this thing was in a complete state, even if his strength increased tenfold, it would not necessarily be its opponent, under normal circumstances, there should not be such an overly powerful life on the surface of the planet.

"This stuff is important to me." The voice of the Starship Hub rang in his head.

"Okay, it's yours."

Qin Feng immediately agreed, it was useless for him to hold this part of his body now, and it was the best choice to give it to the starship to disassemble and absorb.

The clear light flashed, and the body of the unknown creature in the pool disappeared in an instant.

Hundreds of kilometers away, in the City of Blood, a majestic voice full of wrath echoed in the halls:

"I lost sense of part of my body, who is it? Dare to hurt God's body......"
