The sound of teeth biting at flesh and bones is enough to make people creepy to hear.

But Li Ye didn't take this opportunity to pick up the black cat and leave, but stepped forward and slashed at the head of one of the zombies who was eating the four-eyed man!

At the same time, with Li Ye's movements, the zombies suddenly stopped gnawing and turned around at the same time.

Among them, the little boy zombie with a mouth full of flesh and blood suddenly grinned and pounced on Li Ye.

The other zombies Li Ye could still start directly without hesitation, but when he saw the little boy zombie, there was still a slight hesitation.

With just a trace of hesitation, he was directly pounced on by the other party, and opened his mouth to bite directly on Li Ye's neck.

Click!

The tooth was broken, and this bite was directly on the hard mountain opening knife, and at the same time, the knife flashed, and the upper half of the little boy's zombie head fell smoothly to the ground.

"I'm sorry!"

Throwing the body of the little boy's zombie away, the other two zombies had already pounced, secretly saying sorry in their hearts, and kept telling themselves that they were dead! They are no longer humans, but monsters!

Soon, there were several corpses lying on the ground, but Li Ye was also painted on his body, and he was bitten twice by zombies, and a large piece of flesh and blood was even bitten off at the shoulder!

Hiss!

Bursts of inhalation sound came from Li Ye's mouth, and the flesh and blood were torn and bitten off, and the pain was absolutely indescribable.

And at the same time more importantly!

His infection level has increased again!

【Warning! The degree of infection is more than 70%, extremely dangerous, exceeding the critical value! 】

More than 70% of the infections are infected!

Taking a deep breath, Li Ye did not mutate, but a feeling of lightheadedness made him can't help but shake slightly.

"Looks like time is running out, I have to hurry!"

Lifting his spirits, Li Ye walked in front of the four-eyed man and squatted down.

At this time, the four-eyed man was almost angry, his flesh and blood were blurred, and the white bones and bloody internal organs could be seen in many places, and the entire abdominal cavity was hollowed out, that is, his vitality was tenacious, and any ordinary person would have died of excessive blood loss at this moment.

"Save ...... Save me...... Save ......"

The four-eyed man just wanted to reach out and grab Li Ye, but most of the flesh and blood of that arm were gnawed, and when he lifted it halfway, it hung down weakly, and the four-eyed man had no sound, and his eyes were wide with anger until death.

He's dead!

"Damn it!"

Li Ye hasn't had time to ask where the vaccine is! Actually dead!

Picking up the black cat, he touched it in the direction where the giant knife and the four-eyed man appeared just now, and sure enough, a laboratory was close in front of him, blocked by a transparent reinforced glass wall, and one of the doors was wide open, apparently the entrance that had just been invaded by the two players.

When I went in, many instruments were smashed, the whole laboratory was in a mess, many utensils and experimental tools were completely damaged, and some freezers were completely smashed.

Obviously, the giant knife and the four-eyed man searched the whole place in order to find the source of the virus.

"The vaccine should be here! It should be right here! ”

There is no vaccine, and the giant knife and the four-eyed man did not mention the vaccine just now!

However, Li Ye searched for the bodies of the two for a long time, but did not find any clues related to the vaccine, the only possibility is that after the two found the source of the XF virus, they did not have time to find the vaccine, so they were ready to retreat.

As for how they can survive without vaccines, it is obvious that they have their preparations and plans.

Li Ye searched the entire laboratory, but he couldn't find it at all!

As time went on, Li Ye felt that his physical strength was declining rapidly, and he began to weaken.

[Warning, if the infection exceeds the critical value, the immune system begins to die in a large area]

In my mind, the warning of the system has not stopped at all, but if you can't find a vaccine, it means that everyone will die here!

"It shouldn't! It shouldn't be found! Why not? ”

Now that the system prompts the mission objective, it must exist! Even if Li Ye doubted this, it was impossible for him to suspect that the system wanted to kill them.

However, when Li Ye turned over the entire laboratory, he was disappointed to find that there was no shadow of a vaccine at all.

At the same time, his feet were soft, Li Ye's face became pale, almost like a piece of white paper, and his lips were even darker.

There was a faint sound of footsteps in the distance, which made Li Ye's expression froze, but he soon breathed a sigh of relief.

"Uncle!"

"Wood! You're not dead yet, are you? ”

There was a call from afar, letting Li Ye know that the person who came was not a zombie or a mutant, but a trigger and a pink enchantress.

The two also found the laboratory, and when they saw Li Ye sitting on the ground, his face was weak, and they immediately ran over.

"Uncle, how are you?"

The little girl almost pounced, but was pulled by the trigger, because the trigger saw Li Ye's appearance was very strange, revealing a touch of vigilance, "Wood, can you still keep your senses?" ”

As he spoke, he pulled the little girl back slightly, because of Li Ye, a pair of eyes could barely see the pupils, as if there was a mutation, and the lips were black and purple! That kind of look made the trigger's heart sink.

The little girl is not a fool, seeing Li Ye like this, she naturally understands why the trigger asks like that, but she directly broke free of the trigger and directly stepped forward to hug the silent Li Ye.

"Girl, you!"

The trigger couldn't stop it, and he was shocked, but then he was also relieved, because he saw that Li Ye did not open his mouth to bite the little girl's snow-white and delicate neck like those monsters outside, but showed a wry smile.

In fact, from before the two appeared, Li Ye felt that he was about to reach the point of mutation, that feeling was very strange, he knew that changes were taking place in his body, but he couldn't stop it at all.

Seeing the two of them, he even wanted to open his mouth and let them go quickly! Leave with the black cat!

Because he didn't know how long he could keep his sanity, especially when the little girl hugged him, the sweet taste of the little girl's body made him suddenly feel a strong hunger in his stomach!

The white and tender neck is like the most delicious delicacy in the world in his eyes!

Subconsciously swallowed his saliva, after all, reason prevailed over desire, Li Ye raised his head, and saw that the trigger was looking at him nervously, his hands trembled slightly, and he didn't know when he was holding the mountain knife that Li Ye dropped just now, his face was full of hesitation and unbearability.

"I'm sorry, I didn't find the vaccine."

barely said a word, and even the hoarse voice surprised Li Ye himself, obviously even his vocal cords began to be unable to work.

Didn't find a vaccine?

When he heard the trigger, he was stunned for a moment, and then sat on the ground, and smiled bitterly, "Damn, this time it's a big loss, I knew I wouldn't have come to this troubled water, and now I've put my life into it." ”

Without a vaccine, it means that there is no antidote to the virus they are infected with, and even if they run out now, they will only wait for death.

At this time, the pink enchantress suddenly made a move that stunned both Li Ye and the trigger, and directly lowered her head and kissed Li Ye's blackened lips.

"I said that when this is the time, you should not irritate my single dog."

The trigger rolled his eyes, but Li Ye didn't have the strength to stop it at all.

This was not the first time the two had touched lips, but with a deep sense of despair.

After a while, the little girl let go of Li Ye, and she didn't dare to look at Li Ye and buried her head in Li Ye's chest, and even her neck was red.

The three of them are actually waiting for death.

If the task is not completed, the quest will not end.

It is equivalent to dashing the last hope in Li Ye's heart! Originally, he was still thinking that once the copy was over, would it be the same as the last time in the detention center, even if he died frequently, he could come back to life.

However, the vaccine is not found, and the whole copy continues.

Looking down at the black cat that had no reaction, Li Ye felt bitter in his heart, he regretted it! I regret that I have involved other irrelevant people.

"That's not right!"

Suddenly, Li Ye's whole person stood up, and he didn't know where the strength came from, and his eyes, which were almost cloudy, burst out with a gleam.

This time, the little girl was startled, and she didn't care about being shy, so she hurriedly stood up.

"Wood, did you think of something?"

A glimmer of hope flashed on the trigger's face, as long as there was any glimmer of chance of survival, who wanted to die?

"Vaccines! Vaccine! Just now, the two of them didn't seem to be giving up on themselves at all, but thinking about bringing back the virus source body in the black cat's body! They know for sure where the vaccine is! At least know the clues! ”

In my mind, the scene of encountering the giant knife and the four-eyed man before flashed, and the two of them didn't have the reaction to wait for death at all, and they were even in a hurry!

"Seventeen minutes left? What does that mean? ”

Recalling the words of the four-eyed man urging the giant knife to kill him quickly, Li Ye's brain began to think quickly.

"Vaccines, time, tasks, virus sources, damn it! Clues, what exactly is a clue? ”

The more impatient he was, the more clueless he became, and Li Ye felt a burst of sleepiness hit his heart, and bit the tip of his tongue fiercely, and the sharp stinging pain kept his brain awake.

A quick recollection of the tasks triggered after entering the prison, from killing the mutant at the beginning, to finding the source of the XF virus and the vaccine, there are two tasks before and after, if there is any connection between them......

"Wait!"

Li Ye's eyes widened, and his face was incredible!

"Wood, you've got it in mind?"

The trigger also showed excitement, but he saw that the surprise on Li Ye's face was only flashing, and then it was replaced by a mouth full of bitterness, and he was immediately puzzled, "Wood, damn it, you have something to say!" ”

"Uncle! Have you found a vaccine? The pink enchantress also hurriedly asked, can you not die, who wants to die? Just thinking of what she did to Li Ye just now, the little girl almost hung her head down in shame between the two balls on her chest.

"Vaccines...... Maybe I know where. ”

Li Ye held back for a long time and finally spoke.
