As the two spoke, suddenly the nightingale looked back at the empty laboratory passage behind him and frowned slightly.

"What's wrong with you?" , Hao Dongran asked.

"I always feel like a pair of eyes are staring at us...", the nightingale frowned slightly, this feeling was extremely obvious.

As soon as she finished speaking, Hao Dongran nodded: "Are you talking about it?" ”

The nightingale looked in the direction Hao Dongran pointed, and sure enough, he saw a black hound.

There is also a collar around his neck that reads Subject 874.

The nightingale gasped, the number she was all too familiar with.

Before 800, it was all live samples cultivated by C-level vaccines, and after 800, it was cultivated live samples of A--S grades.

A living sample of this level can basically be compared to a tiger-level walking corpse.

"Aren't you capable of controlling the walking dead... Let it go...", the nightingale drew his saber at his waist and bent his knees vigilantly.

After all, this mutant, although it is a canine, is very strong, and once the cells in the body are activated, they are all devastating existences.

Woo...

The black hound bared its teeth and let out a low growl, its back torn and spread.

More than a dozen bright red tentacles swayed wildly, and even the walls of the laboratory, which were comparable to bulletproof glass, began to crack under the beating of the tentacles.

Looking at Hao Dongran again, he swallowed a mouthful of saliva, stretched out his hand and said, "Boom..."

In an instant, the hound roared and rushed forward.

The nightingale didn't hesitate at all, picked up Hao Dongran and ran straight into the depths.

"Didn't you say you could control the walking dead!"

Hao Dongran was trembling wildly, and wanted to explain, but when he saw that the hound opened its bloody mouth and wanted to bite him, he hurriedly shouted: "! ”

"Woooo Shrewd! You're good! ”

Click!

The sound of the upper and lower jaws closing was like thunder, which made Hao Dongran shiver.

"It's broken! Impasse! The nightingale was stunned, and when she turned around, she saw that the hound, which was in hot pursuit, was approaching step by step.

Drawing his knife, he took a deep breath and muttered, "You damn liar..."

"I won't let you go, I'll throw you in the square and whip your corpse when I get out"

Hao Dongran sat up helplessly, looked at the hounds full of tentacles, and couldn't help but shudder.

To be honest, this was the first time he had encountered such a thing.

I don't know what went wrong, this dog actually bit himself...

"No...", Hao Dongran raised his head, looked at the nightingale and said secretly: "It shouldn't be biting yourself"

Nightingale was stunned for a moment, and when he saw him slowly get up and go straight to the hound, he hurriedly said, "Liar, you don't want to die!" ”

Who knew that Hao Dongran waved his hand, or slowly squatted down with the action just now.

Said softly: "Boom..."

The bloodshot eyes of the hound flashed with blood, and the nightingale said secretly: "It's broken! What the hell is this idiot doing! ”

The black shadow rushed away in an instant, and Hao Dongran also let out an exclamation.

But the nightingale, who was about to rush over to save people, was stunned in place, only to see the hound pounce on Hao Dongran like a domestic dog.

Then he was coquettish in his arms, sticking out his tongue and licking Hao Dongran's cheeks as if flattering.

"Stop licking, it's too itchy"

"Good dog! Sit down! Hao Dongran got up and pointed to the hound in front of him sitting honestly on the ground.

Wagging his tail, he looks well-behaved

The nightingale walked over, but in an instant the hound let out a low roar, and his back was about to tear again.

If Hao Dongran hadn't stroked its head again, it would probably have rushed up.

"I'm sorry...", Nightingale apologized embarrassedly.

Hao Dongran waved his hand, "It's okay", Nightingale, this girl is very good everywhere.

It's just that his temperament is too straight, and he is simply a tendon, and he has to be scolded if he can't stop his words.

This can be seen from her shouting with Fuling.

Hao Dongran stood up and was about to speak, when a red light suddenly appeared in the distance.

The rising heat wave was like a pair of invisible hands, overturning the two in an instant.

The hound stood firm, looked into the distance, and rushed out.

Hao Dongran grabbed it, and saw that the nightingale's cheeks were flushed, and he drank: "You don't hurry up!" ”

"Don't say it, your national team's clothes are very good...", Hao Dongran reluctantly let go of his hand, rubbed his trouser legs and lingered a little.

The nightingale rolled her eyes, looked into the distance and whispered, "Let's go"

"I feel like there should be mutants coming along"

Two people in the distance.

One woman and one man.

The man was extremely strong, with a naked upper body, but with a large number of weapons strapped to him.

The portable heavy machine gun on his back flickered even more coldly, and his dark skin looked at the group of hounds surrounding him without any fear.

A woman beside her had protruding bone spurs in her arms, wearing a power suit, her long hair was tied up, and her originally innocent face was a little cold at the moment.

It was some time ago that Hao Dongran saved the woman.

"Old Hei, don't throw bombs, it's very choking", the woman frowned slightly, as if she hated the smell of gunpowder very much.

The man called Lao Hei smiled and said, "Okay."

"Song Nan, excuse me~", Lao Hei took two steps back and gave up his position.

Since the last time Hao Dongran helped her implant a sample, Song Nan's grade has gone from B to A.

Not only the power, but also the speed is very different.

In the face of these more than 300 numbered variants, it is still more than enough.

Lao Hei pulled out a palm-sized iron sign from his back and stood on the ground to envelop him instantly, like a king eight shells.

Only Song Nan's arms shook, and the bone spurs extended to the fingertips, and the last time he said goodbye, the bare bone spurs had already given birth to a sharp blade.

Not much to say, one step out, slashing through the throat of the hound can directly cut off the entire head.

The sharpness can be seen.

After a few moves, Song Nan was like a flower butterfly full of thorns, dancing among the flowers.

Blood poured into the surrounding walls, but not a drop of blood reached her.

After a few breaths, Lao Hei drilled out of the king's eight shells and exclaimed: "Fuck, hang"

"It's okay, it's just that there are no other advanced mutants, so we're going to be faster"

"It's possible that other guilds are also here", Song Nan's eyes flickered when he said this, as if recalling a figure.

I don't know how he's doing now.

Although his body shape and speech are like a retard, he still saved himself.

"Song Nan... What's that over there?", Lao Hei's words brought Song Nan back to his senses.

At a glance, I saw a white figure in a pool of blood.

"Is it a person?" , Song Nan was stunned, and was shocked when he looked closely.

I saw an adult male, wearing a white coat of a scientific researcher, walking slowly with his head down.

His right arm could no longer be called human, and the mutated virus took up almost half of his body.

Swelled, festering, and an extra birth eye, staring at the two of them.

It seems that this eye is his essence, and he has a lot of wisdom.

"Humanoid mutants?" , Song Nan stretched his arms forward, and the bone spurs stretched out vigilantly.

This humanoid variant is rare, and most are hidden in laboratories in the hardest-hit areas.

They were all among the first to be exposed to the virus.

It is very likely that during the transfer, the sample virus was accidentally touched and mutated.

In addition, within a period of time, after continuous devouring to produce independent consciousness, it is very likely to reach the ghost level.

"I guess the smell of blood drew him out"

"Fight? Or do you want to withdraw first? Lao Hei also held the heavy machine gun behind him to his chest.

Song Nan frowned slightly, and said, "It should not be low-level, can the entrance still explode?" ”

Lao Hei nodded, "Yes, but it will take a few minutes, and there are a lot of them outside."

"That's it, let's go another way and come down", Song Nan didn't hesitate at all.

After all, a mutant of this level is not something that can be easily killed.

According to the guild information, the humanoid mutant who has reached the ghost level can weigh thousands of catties with a single blow.

The skin is hard enough to withstand most light rifle bullets.

It's a fierce battle, but for them who are looking for samples, there's no need to waste time here.

It's better to come in again in another place, so as to avoid fighting.

A detonator exploded.

It caused the entire underground laboratory to tremble.

"Flee to the depths!" , Blood oozed from the corners of Song Nan's mouth, and she was now extremely sure that this humanoid mutant had almost reached the peak of the ghost level.

If Lao Hei is also a mutant, maybe he still has the power to fight, but the thermal weapon can't break through the skin of the ghost-level walking corpse at all.

"Damn..."

"Why blow it up again", Hao Dongran swept the dust on his head, looked at the distance behind him and frowned slightly.

"Go get something, hurry, I'll be waiting for you in the office over there", Nightingale glanced at it, and then ignored it.

Instead, she ran straight to her father's office.

Hao Dongran nodded, took out the information card and crossed it, pushed open the door and walked in.

"Are all their refrigerators bought in groups?"

"It's all the same," Hao Dongran muttered, taking out three samples from the refrigerator.

After installing it, I was suddenly stunned, squatted on the ground and saw a sample test tube that had been shattered.

It's not the same as the one he took, it says "Plan R"

"This thing...", Hao Dongran pondered slightly, and suddenly a burst of shouts exploded behind him.

"Daddy!"

When I ran out of the storage room, I saw that the walls of the office had all collapsed.

A strong man covered in blood is being pierced by a zombie with an arm like a telephone pole.

The blood rolling in his mouth, as if he wanted to say something, but he was already dead.

"It's you!"

"It's you!"

The two looked at each other and spoke in unison.
