"Hiss ......"

The alien's sharp scream sounded, and Lu Yuan rolled to his feet, just in time to see the alien screaming and retreating.

"Want to go?"

Lu Yuan chased after him like a gust of wind, and the AA-12 in his hand kept shooting forward.

This is the advantage of shotguns, under high-speed movement, there is no need to deliberately aim, as long as a general direction, just shoot to ensure that the lead bullet covering the past has a chance of hitting.

The alien let out a terrible scream, grabbed the trunk of the tree and climbed up, disappearing into the dense canopy in the blink of an eye.

"The beast is very fast......

Lu Yuan looked up and looked around, finding no sign of movement, and put down the muzzle of the gun, with a solemn look in his eyes.

Even if it was a momentary encounter, it was enough for him to see that the size of this alien was not the original alien, that is, there was already a new alien hatching?

When I watched the movie, I didn't feel that it was my turn to be shocked by the rapid reproduction of this killing creature like an alien.

Chopping grass does not remove the roots and the spring breeze blows and grows, this sentence is used to describe the alien is more appropriate, or in other words, the alien does not need the spring breeze to blow, just leave it alone, it will not take a few times the time for it to recover or even expand to several times the original scale.

It's just that the aliens have come out to sneak attack, so I think the nest is probably around here, right?

Convinced of this idea, Lu Yuan began to search the surroundings, and after a while, he found the corpses of several bats somewhere.

"Saxxy?"

Recognizing the type of bat, Lu Yuan's eyes lit up, "It seems that there is a bat cave nearby." ”

The bats of the subspecies of Sasyani live mostly in deep caves, which is really an excellent choice for alien nesting. What's more, the large amount of bat flesh and blood in the bat cave is just used to provide nutrition for the aliens.

Indeed, he had not walked long this time before he found a two-meter-high cave in front of him.

"This is it, right?"

Lu Yuan reached into his arms, took out the NZT in the small plastic bag from the pocket of his clothes, and swallowed two grains in one gulp.

Then I walked in wearing a night vision device, and the smell of bat feces came to my nose, and there were a lot of unknown sticky things on the ground, so many things left by bat excretion, but there was no movement of a bat, which shows how strange it is.

"Is there really not a single one left?"

Due to the viscous excretion of unknown objects on the ground, stepping on it and walking silently, Lu Yuan carried the gun deep for less than ten meters, turned a corner, and saw seven or eight cocoon-like objects wrapped around the stone wall.

Unlike what I had seen in the mine before, the seven or eight cocoons had a large hole in their chests, revealing the bloody entrails inside, and they were obviously too dead to die.

"Hey, the gang fight is kind of damaging to the prestige of your race, right?"

Only after checking and confirming the deaths of several people, Lu Yuan returned to the center of the cave and spoke.

In the depths of the tunnel, with the ticking sound of saliva flowing, an alien slowly walked out of it. And at the entrance of the cave, the alien who had fled earlier also bared its teeth and grinned iron teeth, and hissed and intimidated Lu Yuan.

The two aliens blocked the passage and started attacking at the same time.

The air seemed to be burning at this moment, Lu Yuan shook his hand is a shotgun, forced back the attack direction of the alien at the entrance of the cave, suddenly turned over to avoid the attack of the other alien's inner nest teeth, and suddenly pulled out the 1911 on his leg, and shot it at the jaw.

The scorching metal bullet instantly penetrated the alien's jaw with super lethality, and this weak part was one of its weak points, and it screamed when it hit a shot.

It was only at this time that Lu Yuan landed on the ground from a 360-degree backflip, without looking, holding a shotgun in one hand, he stabbed out with a backhand, and coincidentally stabbed into the alien mouth cavity that opened his mouth and was about to attack the inner nest teeth.

Then it's a simple pull of the trigger!

"Smack!"

No matter how hard the alien shell was, the inside of the mouth cavity was directly shot by a shotgun, and the crown of the head burst immediately, and the acidic liquid splashed in all directions, and there was a burst of snorting movement, and he died instantly.

The other alien jaw was attacked, and it even wanted to turn its head and continue to eject the inner nest teeth at Lu Yuan, while the sharp blade on the tail flew and attacked at the same time.

One shot to deal with the injured alien, Lu Yuan's AA-12 didn't have time to turn the muzzle, quickly shrank back, dodged the swinging sharp blade, and rolled and raised the gun a few times to shoot.

"Bang ......"

The bullets fired from the pistol, as long as they are not aimed at the weakness of the alien, will eventually be blocked by its shell, producing a burst of thunderbolt sparks, except for the previous heavy damage to the jaw, the alien is unharmed.

But seeing that Lu Yuan, a human being, killed one of his own kind in a few strokes and seriously injured himself, this alien actually climbed on the stone wall, like a gecko, and quickly entered the depths of the cave.

"Don't you dare to fight with me?"

The concentrated effect of a few capsules of NZT in his body made Lu Yuan feel different feelings at this time.

Instead of swallowing a single pill of NZT, he felt his nervous reaction speed faster, and the speed of receiving and processing information was several times faster, as if everything around him was under his control, and nothing could escape his control.

It's just that my head is a little swollen and painful.

"Don't run, it's only been a while."

Throwing away the empty magazine and reloading it, Lu Yuan wanted to shout and cheer excitedly, just death passed by, as long as he slowed down a little, the alien tail spike could pierce his head...... But it didn't hit! This animal is a waste.

It's this feeling of dancing on the tip of the Grim Reaper's knife that is really addictive.

The more excited he became, the calmer Lu Yuan's face became, and he couldn't see anything unusual in his calmness, so he picked up the AA-12 on the ground and walked towards the depths of the cave.

On the other side, following Lu Yuan's instructions, Sonny returned to the camp with five people and immediately began to perform the operation.

Knife, there was a ready-made peeling fruit knife, and after a little sterilization, Sonny pulled the fat man's clothes open and was the first to perform the operation.

Doing surgery is not a very easy thing to do, and the average doctor can only dare to perform surgery alone after several years of clinical practice, and although Sonny is not a medical robot, as a robot serving humans, it itself has instilled a lot of information for emergency treatment.

This medical information, even if it is not comprehensive, covers only a small part, but it is enough to deal with the situation at this time.

The arm made of alloy is as steady as Mount Tai, and it seems to be the most sophisticated instrument between movements, cutting open the abdomen in an instant, and then reaching into the abdomen with the left hand, finding out the juvenile alien in a few clicks, and then cutting the umbilical cord, and completing most of the surgical work.

Seeing the juvenile alien struggle to hiss between his fingers, as if the young bird was lamenting its own fate, Sonny was expressionless and threw himself into the burning campfire next to him, causing the immature hatchling to die quickly in the heat.

Killing a juvenile alien, Sonny pulls out the line from the camp, picks a thinner line, and begins to mend the fat man's wounds in case of emergency.

It took less than seven minutes to get the first operation.

This was followed by the second operation, which was fortunately parasitized by the face-hugging worm, and the narcotic effect secreted would have caused the host to fall into a coma, otherwise the difficulty of the operation would have been much more difficult without anesthetic.

Performed according to the standards of the first operation, Sonny quickly completed the second operation, still mercilessly killing the juvenile alien, and then the third was also successfully completed.

As the fourth operation was about to be completed, Sonny suddenly looked up and noticed something unusual.
