"Boom."

The crisp sound of a bullet landing on the ground appeared in the ears of the two soldiers, and both of them looked down at the same time, only to see a bullet rolling on the ground, and then the two of them felt that the weight of the arm that had been hanging around their necks was gone.

Then, a blood streak appeared in the throat of a soldier, and one soldier was pushed against the wall by Lu Yin with his mouth covered, and a piece of iron stained with warm blood was nailed to his forehead.

The soldier clutched his throat and looked in horror at the man covered in blood, with dirty hair and no shoes on his feet, as if he wanted to say something, but never said it.

Lu Yin casually brushed aside the hair that blocked his eyes, and looked at the retreating soldier with indifferent eyes, "Congratulations on joining the zombie team." ”

After saying that, he took out a few sticks of dead grass stained with black blood from the small pocket of his clothes, and then stuffed the dead grass into the wounds of the two soldiers.

The dead grass was picked up by Lu Yin in the dark prison before, and the black blood on it was deliberately soaked in the dead grass when Lu Yin killed the zombies in the gladiatorial arena.

Originally, Lu Yin planned to stuff this withered grass into the professor's body so that he could also feel the pain of becoming a zombie, but the plan never caught up with the change, and when the professor ordered to pierce Lu Yin's limbs, Lu Yin had a hunch that the professor's patience with him was close to the edge.

Even if you cooperate with the professor and explode the so-called potential, I am afraid that it will be difficult to escape the control of the professor in the end.

So after Lu Yin's limbs were pierced, he deliberately magnified his disdain infinitely and induced the professor to give him a heavy hand, but Lu Yin didn't expect that the professor's patience was so poor, and he directly ordered him to kill himself.

Six years ago, death was terrifying to Lu Yin, but in the five years in the laboratory, Lu Yin no longer knew how many times he had died, and he didn't know how many times he had come back to life.

This may be the luck of the self-healing ability, but it is also the sorrow of the self-healing ability.

Lu Yin took off his clothes, glanced at the wounds that were still bleeding on his body, and then leaned over to take off the soldier's clothes.

In the blink of an eye, all the wounds on Lu Yin's body had healed, and there was no scar left, so he wiped the blood on his body a few times, and then put on a camouflage uniform that was different from his figure, and put on shoes that he hadn't worn in six years.

Feeling the warmth brought by the clothes on his body, Lu Yin wiped the blood stains on his face, then took the dagger off the soldier's body, held the dagger tightly with both hands, and looked at the dark tunnel, Lu Yin knew that if he wanted to be free, this was the only chance.

At the corner of the tunnel.

“120。” Lu Yin leaped out of the darkness, and the dagger stabbed accurately into the throats of the two soldiers.

Two minutes, which is the time for the soldiers to patrol each time Lu Yin was put into the gladiatorial arena for a year, is only ten seconds, and the two teams of soldiers cannot see each other.

After fighting with zombies for a long time, between life and death, it is already easy for Lu Yin to accurately pierce the throat, because the only tools that can be used in the gladiatorial arena are cold weapons and special props formed by the ability to release as companions, so even if there are firearms, Lu Yin also chooses a dagger.

In other words, Lu Yin does not use firearms.

Lu Yin tried to get the bodies of the two soldiers out of the middle of the tunnel, but as soon as he leaned over, the alarm on the wall began to sound.

Lu Yin turned around and looked, it turned out that after a long time of captivity, Lu Yin had forgotten that there was still a surveillance camera. Everything he had just done was not seen by the professor in the monitoring room.

It's just that when he first came out of the gladiatorial arena, the area where Lu Yin killed the soldier happened to be a surveillance blind spot, so no one found out, but the scene where Lu Yin killed the soldier in the tunnel was photographed by the surveillance in the tunnel in all directions.

Lu Yin no longer cared about the dead soldiers, but quickly returned to the prison along the familiar route, because the only place that Lu Yin could find out that could escape during the year was the small window in the prison that was less than a square meter.

After Lu Yin's observation, he was not the only one who lived in the prison he was in, or rather, he was specially arranged by the professor to be in that prison.

Behind the prison is a raging river, and from time to time zombies surface, the professor has placed Lu Yin in that prison in order to completely crush Lu Yin's hope of escape.

It is precisely because of this that the barbed wire on the prison window has been rusted but no one has replaced it, and it is not easy to tear off the rusty barbed wire simply with his fingers, but Lu Yin has two daggers in his hand at the moment, and the sharp military dagger can easily cut the rusty barbed wire.

Even if he fell into the turbulent river and fought the zombies to the death, Lu Yin did not want to be tortured like a guinea pig by the professor again.

Lu Yin ran while avoiding the pursuing soldiers, bullets crossed his ears, and several bullets shot into Lu Yin's body mercilessly, but it did not affect Lu Yin's speed at all, pain, Lu Yin had long been used to it.

"Damn, what kind of monster the hell is he!" The soldiers behind him kept shooting, but they still couldn't catch up with Lu Yin's footsteps, and they obviously saw the bullet hitting Lu Yin, but it had no effect at all.

"Chase! Gotta catch him for me! The professor's angry voice was heard over the interchanger.

The soldier had no choice but to continue chasing, but at this moment, Lu Yin, who had gone and returned, suddenly rushed out from the corner, and the sharp dagger quickly slashed through the soldier's throat and the back of his neck, and some were directly pierced through the heart by the dagger.

For the soldier's attack, Lu Yin didn't care, even if the bullet hit the heart, Lu Yin's expression was still like a pool of stagnant water, indifferent and terrible.

After killing the six soldiers, the remaining soldiers looked at Lu Yin in horror, through the dirty hair, the cold eyes could be vaguely seen, and more than a dozen soldiers were so frightened by Lu Yin's eyes that they did not dare to continue attacking, and even had the illusion that if they moved the dagger in Lu Yin's hand, they would stick it in their chest.

"Kill him!" The professor's voice came from the transmitter again, "What are you doing!" Shoot! ”

Lu Yin didn't say a word, turned around and ran towards the prison quickly, as long as the soldiers he met had only one end, that is, death.

Two minutes later, Lu Yin finally returned to his previous prison.

Not surprisingly, a sharp dagger could easily cut through the rusty barbed wire, and in the blink of an eye, Lu Yin had already cut the barbed wire, and the window of less than a square meter was already enough for him to pass through.

At this moment, there was a gunshot behind him, and a bullet accurately concentrated Lu Yin's ankle, which made Lu Yin have to stumble forward, no matter how fast the self-healing speed was, the impact of the bullet could not be neutralized.

"Run!" The familiar voice came into Lu Yin's ears again, "GA13, you're jumping!" The river outside the window is filled with zombies, and even the river water is the dirty blood of zombies, if you want to become a zombie, then you can jump! ”

Armed with a pistol, the professor said to Lu Yin through the bars of the prison, "Don't think you can escape, it's much safer here than it is outside!" ”

Lu Yin clenched the dagger in both hands, watched as there were more and more soldiers behind the professor, stared at the professor with indifferent eyes, and said nothing.

"I hate the look in your eyes!" After saying that, the professor shot Lu Yin in the eye, and the bullet shot through Lu Yin's eye into the brain.

But this time, Lu Yin did not lose consciousness.

Looking at the professor with one of his remaining intact eyes, a hoarse voice came from Lu Yin's mouth.

"I'll be back."
