Zhang Fan and the friendly clone glanced at each other, and after a moment, both of them nodded slightly.

Then, the friendly clone said to Zhang Fan: "I'll go up and have a look first, there is no danger for you to come up again." ”

Zhang Fan did not speak.

The friendly clone immediately took a spear and walked cautiously up the stairs.

The staircase was about twenty steps, and it was quick to get to the top.

After looking at it for a while, he said to Zhang Fan: "It doesn't seem to be in any danger." ”

Zhang Fan immediately walked briskly towards the stairs, and soon came to the upper floor.

There is still only one passage here, which stretches into the distance.

Zhang Fan and the friendly clone cautiously walked forward along the passage.

It wasn't long before a metal door appeared in front of the passage.

Zhang Fan could hear the sound of sizzling from the door.

Obviously, there are zombies in there.

Lying on the gap under the door, I glanced inside, and saw that there were more than twenty zombies inside.

It looks like they're all blood-beaded zombies.

Just when the two of them hesitated to go in, the communicator above the passage once again heard an electronically synthesized female voice.

"As long as it is a zombie above level 2, the brain has a blood nucleus. Your constitution determines that you can increase your strength as long as you devour the blood core. And devouring the blood core can also reduce the hunger in your belly. So, you don't have to eat people. ”

The friendly clone listened and said angrily, "Since you don't have to eat people, why do you force us to eat? ”

"This is to test your minds. If you are not determined, we will not let you go. ”

Zhang Fan listened, and kicked open the metal door.

The blood-beaded zombies inside immediately roared and pounced.

Through the words of that voice, Zhang Fan already knew that they had really classified the zombies.

These zombies that have a little human consciousness are the level 2 zombies in their mouths.

Zhang Fan and the others quickly dealt with the more than a dozen level 2 zombies inside.

It's still the same as before, whoever solves the zombie will own the blood core inside.

The friendly zombie swallowed only four blood cores.

Zhang Fan swallowed ten.

In Zhang Fan's body, the feeling of imminent promotion became stronger and stronger.

It's just that he found that the blood cores of these level 2 zombies could no longer satisfy him.

It seems that the higher the level, the higher the level of blood cores required.

After eating the blood cores, the two continued along the passage.

There was another room in front, and in this room, they encountered five level 3 zombies.

Level 3 zombies are zombies with the strength of little Lori.

They are extremely fast and powerful.

Level 3 clones are no match for them at all.

But now Zhang Fan is already level 4.

And he learned to draw his sword and slash, it is not too easy to deal with these level 3 zombies.

The friendly clone didn't even have time to make a move.

The heads of the five level 3 zombies were all split open by him.

Picking up the 5 blood beads, Zhang Fan took out one of them and slapped it into his mouth.

The cold feeling came again.

From his stomach, it spreads throughout his body.

Every cell seems to be frozen.

But in the midst of this ice, cells seem to be evolving at a breakneck pace.

Zhang Fan's heart moved: I'm going to be promoted!

Since he was about to be promoted, he first kept the remaining four level 3 blood cores.

If he is hungry for a long time in the future, he can use these blood cores to satisfy his hunger.

Five minutes later, in Zhang Fan's body, that cold feeling reached its peak.

At the same time, he suddenly felt that his body was filled with strength.

It's as if you can destroy the world with one punch.

"Finally promoted to level 5!"

Zhang Fan secretly said excitedly in his heart.

According to the previous convention, starting from level 2, the strength increased by 500 kg for each level of promotion.

Then now his strength should be able to reach two tons.

With two tons of power, what a horror it must be.

Even if it is an elephant, under the attack of his two tons of strength, I am afraid it will not be able to eat it.

Seeing that Zhang Fan's body was light and radiant, the friendly clone also said happily: "You have been promoted to level 5?!" That's great! ”

Zhang Fan nodded and said, "But it's better to be careful." Let's move on. ”

The friendly clone nodded.

The two moved on.

Half an hour later, they finally reached the end of the passage.

This is an office-like hall.

Behind the high-tech floating desk, there is a person.

I saw that this person was wearing a white uniform.

He was in his forties and looked lazy.

He leaned back in the chair behind the desk.

On his right arm, he was wrapped in a bandage.

Seeing this scene, Zhang Fan suddenly remembered.

"You ......"

Without waiting for Zhang Fan to finish speaking, the man answered: "301 laboratory, zombie breeder." No. 9527. ”

It turned out that this person was the one who Zhang Fan had crushed his hand bones at the beginning.

9527 glanced down at his bandaged right hand and said, "It's all thanks to you." ”

The friendly clone said, "Don't talk this nonsense. We just want to know the truth of all this. Why clone us, and why do we want to eat human flesh so much? We can exempt ourselves from the zombie virus, and when we finish eating the blood core, the level will increase...... What is the reason for all this? ”

9527 chuckled twice and said, "The reason why you want to eat human flesh, be immune to the zombie virus, and eat blood cores to increase your level is because we injected you with the zombie virus. ”

"Why?"

"Because we want to make you super warriors. Only by injecting the zombie virus can you quickly improve your strength by devouring the blood core, so as to become a powerful super warrior in a short period of time. ”

"Warrior?"

Zhang Fan sneered: "What the hell is a martial artist?" Is there such a thing in our world? ”

9527 looked lazy, slumped back in his chair, and said, "This is not the world you remember anymore. In this world, humans make up only a small part. Zombies and other monsters make up a large portion. In order to deal with zombies and those monsters, humans use drugs to activate their talent genes and thus become warriors.

However, the cultivation speed of martial artists is too slow, and only a small number of people can become top martial artists.

But it is obviously not enough for such a few top martial artists to deal with the zombies in the outside world.

That's why we developed this project to create a super warrior using the zombie virus. Not afraid of virus infection, but also can quickly improve strength.

As long as you keep eating the blood core, you will definitely become an invincible existence in the future.

So, you are the hope of this world.

It's just that there is one thing in this: after being injected with the zombie virus, I am full of craving for human flesh.

So we have to make sure that you are strong-willed and strong-willed.

And the two of you, obviously, have met the mark.

You are the only two of the 100 clones to succeed. ”

When Zhang Fan heard this, his brows furrowed.

After a few moments, he asked two questions.
