“…… The tenacity of life is far beyond human imagination, not to mention the earth's native microorganisms that may fly to other planets with artificial devices, even many organisms that are 'fragile' from a scientific point of view are likely to evolve and survive in extreme natural elimination, and the strength of human adaptability is a problem that the scientific community cannot agree on......"

"This ...... To be honest, I don't know what to do either. ”

Jiesi stood next to Ling Yu, her voice very soft, as if a slightly louder voice would wake up this town that had been sleeping for 150,000 years.

"Is there anything that can give us clues, such as the main computer, information logging or something?"

Ling Yu turned around, walked around the flower bed, and cautiously walked to the door of a house with a gun, and put his hand on the platform next to it, which resembled a palm pattern lock.

There was a flash of yellow light on the platform, and there was no more reaction.

"The genetic locks in these rooms should be for the owner himself, and the boss should not be able to open them."

Jesse walked to the door with hindsight, thought for a moment, then raised her right hand, twisted the glove in her right hand, and took it off!

"Hey, hey! You ......"

"It doesn't matter, I made a seal on my wrist." Jess raised her arm to indicate that it was okay, "I expected this to happen, so I prepared. ”

"Are you going to smash this door open?" Ling Yu walked to the door and knocked lightly on the metal door, the echo was muffled, "Solid metal." ”

"Try it, the place where it is connected should be fragile after so many years, and even if it doesn't work, there are windows." Jesse took a few steps back, took a breath, and sprinted forward, slamming her fist into the metal door.

"Boom-"

Unexpectedly, not only was the door opened, but the entire metal plate was blasted out like a cannonball, twisted and deformed into the wall behind.

"It seems that we overestimated the civilian material technology of prehistoric civilizations." Ling Yu lifted Jiesi, who almost fell down due to inertia, from the back collar, "If this kind of Cheng dù is used, I can open it with a roundabout kick." ”

"Uh, uh, civilian materials." Jessie nodded, smiled awkwardly, and immediately changed the subject, "Otherwise, boss, let's search separately, I'll search the other side, and you search this street." ”

"Hmm......" Ling Yu hesitated for a moment, but turned his head to look at the door panel that had been punched at a hundred and twenty degree angle and was still deeply inserted into the wall, nodded, and raised his hand to point to his helmet, "Anyway, be careful, contact me immediately if there is any situation." ”

"Understood~" Jesse saluted a knightly salute, but the tongue stuck out behind the translucent helmet made this action not solemn.

Looking at Jiesi who turned to leave, Ling Yu sighed and turned his head to start his search.

****

The living quarters were not large—only two streets, about twenty small two- or three-story buildings, to be exact, and after finding nothing in the first room, Ling Yu began a tedious and vigilant search process.

Most of the rooms were only a few pieces of metal furniture, or rather, the metal part of the furniture, Ling Yu didn't know if there were sofas in the living rooms of prehistoric civilizations, but judging from the large swaths of emptiness, prehistoric civilizations also preferred wood - or other materials that might completely disappear in 150,000 years to make furniture.

Nothing.

"Is there any progress on your side?" Ling Yu had almost reached the end of the street, and all the rooms he had scanned had no trace of electronic products, he slowly withdrew from the room, walked to the empty street, and spoke.

"No," Jesse's voice was soft, "if you're unlucky, you'll have to go to the next living quarters to find it." ”

"I'll try this, maybe something will come out of it." Ling Yu turned around and his gaze fell on a small building at the end of the street - the reason why he had jumped over the other three closer rooms was that this small two-story building hidden in the innermost part of the street seemed to be a little larger than the others.

Ling Yu trotted all the way through the street to the front of the building, and to his surprise, the building's electronic door was actually open.

Ling Yu cautiously took a few steps forward, but suddenly Jiesi's voice came from his ears.

"Wait, boss, it's not right."

"What's wrong?"

"The thickness of the dust is uneven, it is not naturally formed, I scanned it, it was obvious that there was biological activity, and then covered up the signs of my tracks."

"Looks like we're in company," Ling Yu clenched the handle of the gun, and then relaxed himself again—exerting too much force would stiffen his muscles and reduce his reflexes, "Can you tell what type it is?" ”

"It's a bit like some canines on Earth, but it's a bit clumsy compared to animals on Earth, and it may be artificially camouflaged."

"Understood, I'll be careful."

Ling Yu stepped through the door, carefully watching every corner of the house, and after confirming that it was safe, he activated the scanner.

"Didn't you ......?"

The scanning progress of the room quickly exceeded 90%, but there was still no response from any electronic signal, however, before the disappointment spread, suddenly, the green window filled Ling Yu's helmet with a crisp ticking sound!

"Jeunse, there's a harvest, I'll take a look."

"Be careful."

Although Jiesi couldn't see it, Ling Yu nodded subconsciously, he followed the prompts of the scanner, walked to the place that was half a wall away, about the dining room, and according to the instructions of the helmet monitor, he squatted down and reached out to find a translucent man-made object in the accumulated dust.

"Is this the thing?" Ling Yu carefully examined the sliced sample in his hand, like a plain piece of glass, neither glowing nor anything special.

Ling Yu's fingers pressed slightly, and the metal outline shattered with a click, and Ling Yu was startled—something that was so easy to find must not be damaged.

"Boss, insert the chip you found into the slot on your waist, I installed a 3D scanner over there, I'll get the information first and see if I can copy it."

"Hmm, okay." Ling Yu, who was a thief, carefully restored the shattered metal outline, and then inserted it into the scanner on his waist.

However, in the next second, Ling Yu took advantage of the situation and grasped the dagger behind his waist!

A huge sense of danger came from behind, and Ling Yu instantly made three reactions - kicking his legs forward and then turning around; Keep the Enigmatic Pistol in front of you; As well as the face armor of the helmet was closed.

And this last action, without a doubt, saved his life.

Then, he clearly felt a huge impact force on his head, and the young man who had just finished turning over was pulled out like a slap in the face from the left side.

The helmet's visor shattered instantly, shattering along with the transparent visor that could withstand direct rifle fire, and the system immediately responded with the shattering of the visor - a blue translucent sealed eyepiece popped down from the top of the helmet, and together with the soft breathing mask that popped underneath, Ling Yu's entire face was protected.

Ling Yu, who was hitting the wall, looked at the black shadow that flashed by, and quickly raised his pistol, a rainbow-colored light streaked through the air, but it couldn't prevent the black shadow from hitting Ling Yu's chest directly.

The entire wall was completely shattered, but Ling Yu also drew his dagger, and the three-edged thorn stabbed at the black shadow in his arms, Ling Yu only felt that the dagger was as difficult to penetrate as if it had pierced into the granite.

The mysterious pistol with the black shadow spewed out rainbow-colored light again, and the black shadow that had been shot twice in a row let out a wail and was kicked away by Ling Yu.

It was only now that Ling Yu could see his opponent clearly.

It was a canine, larger than a wolf, about the size of a lion, with razor-sharp nails on its paws—the culprit for the shattered helmet.

In addition, its weapons should also have sharp teeth, as well as a stegosaurus-like back knife on its back.

Ling Yu lowered his head, and the pain of the impact slowly receded, replaced by a tearing pain—the incision from the chest to the lower abdomen about 20 centimeters should be the masterpiece of the monster's back knife in front of him.

Ling Yu clenched the dagger in his left hand, the dagger's attack just now had no effect, because he found that in the front head and shoulders of this wolfdog monster, there was a layer of organic carapace that was almost the same color as the skin color, and the hardness should probably be no less than granite - according to the test of the knife just now, the thickness was unknown.

"That's right, you don't need to use these troublesome things."

Ling Yu raised his hand to take off the broken helmet - in fact, Ling Yu had proved last time that once the power system was activated, the environment on the ship would not be fatal at least.

Throwing the helmet on the ground, Ling Yu's gaze returned to the monster that also did not attack in place, the most effective weapon was obviously the mystery pistol, the red and black blood flowing from the monster's abdomen and chest proved this, but the problem was also obvious: the mystery pistol that had no stopping effect was obviously not suitable for dealing with such a monster with a melee attack.

Just as Ling Yu was about to continue watching, the monster suddenly moved, and the black wolfdog kicked its limbs, opened its mouth and pounced on Ling Yu with its fangs exposed.

Ling Yu dodged sideways, and shot at the side of the wolfdog, a hole of 2.5 centimeters appeared in the monster's waist and abdomen, but the wolfdog was completely unmoved, and immediately adjusted his posture in the air, and bit down on Ling Yu's arm holding the gun.

However, before its drooling teeth could touch Ling Yu's right hand, the dagger in its left hand flashed down from top to bottom and slammed down on its head!

The reason why "smash" was used instead of "piercing" was because Ling Yu didn't expect this blow to be slid away - the semicircular skin armor of the hard head slid through Ling Yu's dagger.

And Ling Yu realized that he hadn't opened the electric heating sheet on the dagger until now!

This mistake caused Ling Yu's right arm to be cut a bloody mark by the monster's teeth, and Ling Yu, who was left behind, did a backflip and kicked the monster's chin with both feet, preventing the possibility of the opponent's pursuit.

Ling Yu, who turned over and landed, did not hesitate, and fired two shots in a row to empty the battery in the mystery, as if sensing the threat of the mystery pistol to himself, the monster who also adjusted his posture and pounced on it deftly twisted his body, avoiding Ling Yu's aiming head.

Ling Yu, who threw away the mystery pistol with his right hand, instantly turned on the overclocking and rushed straight towards the monster, and the subsonic attack punched the monster in the head!

However, Ling Yu didn't let it go, realizing the danger of this monster, he kicked the ground with his right foot, followed the monster that was sent flying, and rushed out, sticking to the monster flying backwards, and slammed his knee into the monster's soft abdomen!

Under the action of huge inertia, one person and one monster directly smashed through the ancient metal wall and rushed onto the street!

"Do me a favor! Jeunse!! ”

Coincidentally, the moment he rushed out of the wall, Ling Yu suddenly spotted Jiesi who was running towards this side, and immediately changed his strategy, kicking the ground again to keep up with the monster that was still floating in the air, and kicking it in the direction of Jiesi.

Jiesi, who comprehended her mind, showed her mechanical right arm and punched the monster flying towards her in the back, and Ling Yu, who was running at the speed of sound, followed one after another, and hit the monster in the abdomen with a knee!

The monster's solid body was finally no longer able to withstand such a violent continuous impact, and was torn apart by two huge reverse forces from the back and abdomen, and was "cut in two" along the bottom of the chest!

A miserable howl erupted from the monster's mouth, and along with it flew into the sky with dark red blood, and Ling Yu jumped high to make sure of what happened, and pierced the shortsword that had been warmed up from top to bottom through the monster's wolfdog-like head, nailing it to the ground.

Brilliant flames burned along the dagger, and Ling Yu let go of the handle of the knife and took a few steps back - the highest power of the electric hot knife was nearly three thousand degrees Celsius, and the fat and muscles of the monster were directly ignited, and the upper body was cremated.

"Boss, are you alright!! Where's your helmet?!! ”

It's over, I'm going to be annoyed to death now.

Listening to Jiesi's reproachful and concerned voice, Ling Yu was stunned for a moment and thought.
