Due to the detachment of scales on the surface of the body, F0905's defense against bullets was greatly weakened, and the large-caliber full-power rifle bullets finally managed to tear through its skin and penetrate its body.

The kinetic energy attached to the bullet is terrifying, even close to the power of the rapid-fire Gauss pistol, and in order to cause greater damage to the target, the inside of the bullet has undergone special treatment.

The front end of the warhead is wrapped with a layer of tungsten alloy armor, so that the bullet has excellent armor-piercing performance, and in the middle of the warhead is left a cavity, the cavity is filled with high explosives and metal sand soaked in biological agents, when the warhead penetrates into the target's muscles, due to the effect of air pressure, the miniature fuse inside the warhead will detonate the explosive, so that the middle end of the warhead will explode directly, and the quenched highly toxic metal sand will frantically drill into the target's body. It creates a large number of cavities and volatilizes the effects of the poison.

This design has improved the lethality of conventional rifle bullets against living beings to the extreme, and when a large number of bullets explode in the target's body, even high-level mutant creatures cannot withstand the damage from the body.

F0905's struggle finally faded into weakness, and he finally fell to the ground, motionless......

……

……

In the last twenty-five minutes until four o'clock in the morning, Qi Lin finally found one of the entrances to the underground vault in Fort Yukon.

As expected, there were far more guards at the entrance to the passage than there were elsewhere, and two heavy power armor with Gatling cannons were stuck in front of the closed metal door. Eight searchlights focused the light on this place at the same time, and Qi Lin could even see the red dot bright spot formed by the laser sight of the multi-barreled machine gun on the guard tower moving back and forth on the ground in front of the passage entrance...... Forcing a breakthrough has no chance of success, and it is also difficult to sneak in.

There are only twenty minutes left......

If this is compared to a game dungeon, the current difficulty can only be counted as heroic at best, and after 4 a.m., the difficulty of this dungeon will be directly upgraded to the next level of Nightmare.

There are so many guards at the entrance under normal circumstances, and it is not difficult for Qi Lin to imagine how much the defense force at this entrance will be strengthened after the entire Fort Yukon base is put under martial law.

At that time, it is estimated that the entrance will be crowded with guards, even if these guards ignore Qi Lin, Qi Lin will not be able to squeeze through the human wall composed of guards.

At this moment, the sound of chains dragging on the ground faintly came into Qi Lin's ears, not only the sound of chains rubbing against the ground, but also the sound of a man's muffled snort and the sound of military boots kicking and beating.

Under the cover of the night, Qi Lin quickly changed his position with his waist bent, and soon, three people walking in this direction entered Qi Lin's field of vision.

A researcher in a white lab coat, a white mask and a white hat, a naked prisoner with shackles and chains around his neck, wrists, and ankles, and the last one an ordinary soldier, holding a chain in one hand and a riot stick wrapped in rubber at the tip of the other, drove the prisoner in front of him like a pig, and occasionally raised a kick and kicked the prisoner in the thigh or buttocks.

Looking at the white coat leading the way in front, the prisoner seemed to have known his fate, and his face was painful and reluctant, if it wasn't for someone rushing behind, it is estimated that he would have been lying on the ground and not getting up.

This...... Seems like an opportunity......

Qi Lin had noticed before that the metal door leading to the underground used an electronic lock, but unlocking did not require a password, fingerprint and iris verification, and only needed to swipe the magnetic card in the card slot, and the magnetic card was now attached to the researcher's work card and hung on his chest.

The alley they are passing through now happens to be without patrolling guards, and there is no chance to miss it, Qi Lin dodged, that is, he had already appeared behind the soldier, and with a knife blow, the soldier fell softly, Qi Lin reached out to catch him, and then silently laid it flat on the ground.

Until this time, the researcher who walked in front was unaware of nothing, and it only took Qi Lin less than half a second to crush his throat from behind.

After putting down the two men, Qi Lin lifted the stunned prisoner from the ground, first covered his mouth with his hand, and then asked in a low voice, "Do you want to live?" ”

The prisoner's eyes widened, then he nodded vigorously.

"Very well, you should also know what happens if you are sent to the laboratory, if you want to survive, you can do what I say."

The prisoner nodded again.

"What's your name?" Qi Lin lowered his hand covering the prisoner's mouth.

"Lu, Lucas."

"Remember, Lucas, I need your cooperation with me, I need to go through the entrance in front of me and enter the underground shelter......"

When he heard Qi Lin mention the word "underground", a look of fear appeared in Lucas's eyes, obviously, the laboratory located underground left a lot of shadows in the hearts of these people.

"Don't be nervous, there are other exits in the underground shelter to get out of this place, but first, you have to help me, otherwise, none of us will be able to get out." Qi Lin said as he used a thin wire to pry open Lucas's handcuffs and leg irons.

"I ...... What should I do? ”

"Go take the guy's clothes off and put them on, and chain them up to him." Qi Lin said that he had dragged the researcher's body to the dark, and then took off the white coat and put it on his body.

Then, Qi Lin pushed open the cover of the drainage channel in the corner of the wall, and pushed the corpse of the researcher with only his underwear and his own excess equipment into the drainage channel.

Perhaps out of fear, or perhaps because of nervousness, Lucas's hands shook violently, but his movements were not slow at all, and in less than a minute, he had completed the task given to him by Qi Lin.

"What's next?" Lucas, who had already put on a soldier's uniform, turned his head to look at Qi Lin, who was dressed as a researcher, and asked a little nervously.

"Don't be nervous when someone comes, just think of yourself as a soldier escorting prisoners."

"Okay, okay."

After speaking, Qi Lin bent down, stretched out his hand and tapped the soldier's throat hard, and the dark energy transmitted from the past directly cracked the soldier's vocal cords, and at the same time, the soldier also woke up in a violent cough.

"Beat him!"

Qi Lin shouted in a low voice as he kicked the soldier in the abdomen

Lucas was stunned for a second, but he quickly understood Qi Lin's intentions, raised the riot stick in his hand and slapped the soldier's body.

And Qi Lin kicked the soldier's face several times in a row, and the hard toe with steel plates inside kicked the opponent's entire face into a bloody blur, and his original appearance could no longer be seen at all.

Coupled with the destruction of his vocal cords, the soldier could only let out hoarse cries of pain constantly, unable to speak at all.

The commotion quickly attracted nearby patrol soldiers, who saw the scene and quickly ran over.

"Hey! What happened?! ”

"This guy wants to escape." Qi Lin replied coldly, and kicked out again, this kick happened to hit the opponent's crotch, and the opponent's whole person curled up into a ball because of the severe pain.

“…… Well, do you need us to escort you over? It didn't seem to be the first time this had happened, and the patrolling soldiers looked unsurprised, scanning the "prisoner" who had fallen to the ground and twitching without a hint of pity.

"That's for the best, but I'll have to calm him down first." After speaking, Qi Lin took out a tranquilizer from the pocket of his white coat, pricked it on the neck of the "prisoner", and pushed all the drugs in it into it.

In addition to a few sedatives in the researcher's white coat, there was a pocket pistol for self-defense, and it was clear that in desperation, there were many prisoners who would jump over the wall in a hurry, and these things were prepared to deal with that situation.

As the effect of the sedative began to take effect, the "prisoner's" breathing gradually calmed down, and the convulsions of his body became much smaller.

It's just that due to the accumulation of dark injuries on his body, when he carried the "prisoner" on his shoulder, Lucas's left leg suddenly weakened, and he almost fell to his knees.

"Are you alright?" This situation immediately attracted the attention of the soldiers, and one of them asked.

"It's okay...... Just got hit on the knee by this bastard...... Hiss...... It hurts a little bit......" Lucas reacted very quickly, and in the blink of an eye, he made up a perfect excuse.

"Let's go, we'll escort you to the entrance, but the road below isn't for us to enter, if you still need to be escorted, I can help you contact the troops below."

"No, that's enough." Qi Lin replied lightly, flicking the empty syringe with his fingers.

Under the escort of this group of soldiers, Qi Lin and Lucas soon arrived at the entrance, and those soldiers guarding the entrance seemed to be very jealous of Qi Lin's identity in a white coat, and they didn't even interrogate, so they consciously gave way to the sides.

Picking up the magnetic card and swiping it lightly on the electronic lock, the metal door slid silently to the sides, Qi Lin turned his head to take a look, and then took the lead and walked inside.

It wasn't until the metal door closed behind him again that Lucas, who was carrying the "prisoner", let out a long breath.

But now is not the time to relax, there are also guards behind the door, although there are not as many as outside the door, but they obviously have higher authority.

"What's going on? What's wrong with this 'sample'? Is he dead? A guard stepped forward to stop them and asked, pointing to the "prisoner" who was being carried on Lucas's shoulder.

"It's just a sedative." Qi Lin's voice without a trace of emotion came from under the mask.

"Another one who wants to run away? …… Hmph, I can't help myself. The guard glanced contemptuously at the "prisoner" who was being carried on Lucas's shoulder, and moved out of the way, "You'd better hurry up, Dr. Horford has been waiting for a long time." ”

"I know, I don't need you to rush me." Qi Lin glanced coldly at the guard and walked over with Lucas.

"Wait a minute...... It was Researcher Conrad who was going to use this 'sample', not Dr. Horford at all! Who are you? The guard suddenly shouted, and at the same time raised the weapon in his hand, aiming it at Qi Lin and Lucas.

"Why are you so excited? Oh, by the way, you're just a watchdog, of course you don't know that this 'sample' was what Dr. Horford asked Researcher Conrad to find, and the experiment that was going to use him was also led by Dr. Horford, and I just spoke to Dr. Horford, how about it, do you want to confirm with the doctor? …… A shitty watchdog? Qi Lin turned around and pointed to the headphones hanging from his ear, which had also been taken off the researcher's body.

"You ......" The guard was completely stunned by Qi Lin's words, and after a long time, he said hesitantly: "It's just a lowest-level third-class researcher...... You'd better pay attention to your attitude! ”

"I'm sorry, but if this experiment had been successful, I might not have been a third-class researcher, and you've always been just a watchdog." Qi Lin narrowed his eyes and looked at the guard with an extremely dangerous gaze.

“…… Let's go, next time...... You'd better not let me bump into ...... alone" The guard dropped a cruel word and retreated, it was obvious that Qi Lin had made the right bet this time, and the other party did not take further action...... Most of the researchers who live underground all year round have strange tempers, especially those who are in high positions, and no one dares to take the initiative to provoke them, and if they are not careful, they are likely to be used as samples for experiments......

Qi Lin and Lucas quickly passed through the guarded passage and turned into an alley, and Lucas immediately threw the prisoner on his shoulder to the ground, leaning against the wall and gasping for breath.

"Damn...... Damn it...... I thought I was going to be discovered......"

"I thought so too, but luckily, the guard looked quite sluggish, but in fact he was very cowardly."

"Who the hell are you? Do you really know Dr. Horford and Researcher Conrad? How can you be sure that those words will fool the guard? Lucas asked, curious.

"I said it casually, I don't even know if Dr. Horford really exists, anyway, the other party is already suspicious, it's better to take the initiative and give it a try." Qi Lin said with a smile.

"So what if the other party doesn't believe it? Or is Dr. Horford the one he made up to test you? ”

"Then I'll have to kill all the guards." As he spoke, Qi Lin stretched his hand out of his pocket, but what he was holding in his hand was not the researcher's pocket pistol, but a Gauss pistol with a silencer.

Lucas's mouth opened slightly, and his stunned expression lasted for a few seconds before he exhaled heavily and asked again, "Who are you?" ”
