National Doomsday: I am the master of viruses, I evolve by eating poison

These rats that rushed over undoubtedly stepped into the virus fog.

The originally flexible bodies suddenly stagnated.

But they did not immediately transform into zombies, there is always a process.

Su Yunfei was not in a hurry.

Another group of rats climbed up.

Entered the poisonous fog.

When there were almost hundreds of rats around.

Su Yunfei used the secret technique lightly.

"Nightmare Abyss!"

Rats are creatures with pitifully low mental power.

Only the most basic nightmare secret technique is enough to completely control them.

Su Yunfei instilled a thought in them: "Bite, bite your own kind!"

The invisible black net enveloped them, and these hundreds of rats were all like being fixed, unable to move forward.

After a while, they moved and began to flee in all directions.

But they did not dare to take a step towards Su Yunfei.

In their subconscious, it was an extremely terrifying existence!

This was the effect of the nightmare secret technique, which made them feel the crush of mental power.

Not long after, the mice infected with the zombie virus and the nightmare secret technique fell from the building and fell into the rat group.

They immediately opened their mouths and bit their companions without knowing why.

The bitten mice felt pain and immediately became angry and bit back.

In this way, unknowingly, the zombie virus began to spread from one to ten, and from ten to a hundred in the rat group...

During this period, there were constantly rats climbing to the roof.

The virus fog around Su Yunfei became more and more dense as it accumulated.

"The consumption of energy release is acceptable..."

It's similar to the extraction, and the energy release is basically dozens of dozens.

As for the mental power consumed by the nightmare secret technique, it is not a problem for him at all.

Take a break and you can replenish it.

That's it.

The zombie virus, coupled with the mental control of the nightmare, infected batches of mice with the virus and fell into the rat group again.

The virus's self-replication speed is amazingly fast.

Gradually, more and more rats were infected with the virus below.

They ran farther and farther.

They took the virus far away.

There were also endless rats rushing here.

But.

For the entire wilderness, Su Yunfei's location was too small.

There were more rats who didn't pass by here at all and went straight to the base in front.

Su Yunfei didn't care and increased the intensity of virus release.

A large amount of poisonous fog was directly sprinkled from the upstairs to the place where the rats were most dense.

In just two minutes, these originally black and brown rats had green light on their bodies.

They have gradually become zombies!

...

Ten minutes later.

System prompt:

[The virus you released has successfully infected 2813 rats! ]

...

Twenty minutes later.

System prompt:

[The virus you released has successfully infected 38604 rats! 】

…………

Thirty minutes later.

System prompt:

[The virus you released has successfully infected 567,782 mice! ]

…………

This number is still growing at a terrifying rate!

Because, if the zombie rats infect other mice, it is still considered the virus released by Su Yunfei.

Su Yunfei was surrounded by thick poisonous fog, and he couldn't help laughing at the zombie rats below that were slow to move and doubly aggressive.

"I'm such a devil... No, little clever ghost!"

However, the mice coming from the back didn't know what happened in front, and kept squeezing forward.

So, they were bitten by the zombie rats.

More and more mice were infected!

Even.

There were other animals affected.

[The virus you released has successfully infected 35 wild dogs! ]

[The virus you released has successfully infected 48 crows! 】

【……】

For a while, many animals were turned into zombies.

Su Yunfei did not get any rewards from it.

It was just that his skill proficiency was rising.

【Energy Release】 has been upgraded to proficiency level!

【Nightmare Abyss】 has been upgraded to master level!

In addition.

Outside the base, there are tens of millions of level 1 zombie rats and other monsters.

After killing them, more energy will be credited...

When other bases were busy dealing with the beast tide and could not upgrade, the 3418 base did not delay the upgrade.

This in itself is a huge gain!

Su Yunfei also tested it himself.

【You killed a level 1 ordinary zombie rat and gained 5 energy points! 】

【Extraction successful! 】

【You converted 1 energy from a level 1 ordinary zombie rat! 】

A zombie rat can get an average of 6 energy points.

AndIt takes about 40 to 50 energy points to release the poison mist once, and hundreds of rats are infected in the primary stage, and countless rats are infected in the secondary stage.

On average, the cost of infection for each rat is 0.5 energy points.

So, even if Su Yunfei kills the zombie rat and does not extract the corpse, he can still earn 4.5 energy points.

After a quick calculation, Su Yunfei showed a happy expression and couldn't help laughing:

"I really earned money! I figured out the system bug!"

..................................

However.

Ideals are full, but reality is very skinny.

Even if there are hundreds of thousands of zombie rats, Su Yunfei can't kill them all one by one.

The zombie rat group, as a whole, is gradually moving towards the base.

There are still a steady stream of wild rats behind.

Su Yunfei has been staying in the bungalow, creating groups of zombie rats.

In the base.

Many people have already noticed the changes in the rat group.

"What's going on? The rats seem to have turned into zombies?"

"Haha! Level 1 zombie rats are monsters and can't enter the base!"

"This is great! If the rat tide is really endless, the base will be breached sooner or later, and then we can only hide in the safe house..."

"Brothers, follow me to kill!"

"Hahaha! There are still so many level 1 zombie rats. Don't we have to upgrade quickly?"

The zombie rats are more ferocious and attack anything that moves.

But their movements are indeed slower than before.

For the survivors, it is easier to kill them.

For a while.

Many people in the base were excited.

Even though it was night, they ran outside the gate and started to beat rats crazily.

Of course, everyone didn't dare to go too far, after all, there were other powerful monsters wandering nearby.

Not long after.

In the base channel.

All positive feedback.

"I'm so happy! My energy is rising!"

"I'm so happy, so happy, I'm so moved, zombie rats are so cute!"

"I won't sleep tonight! Upgrade, war merit, I want them all!!"

No one thought of Su Yunfei.

Everyone thought that the rat tide was like this.

At first, low-level rats appeared, and then higher-level zombie rats appeared. Isn't this reasonable?

…………

Su Yunfei glanced at the chat in the base and smiled slightly.

He looked at the regional war merit rankings again.

Their base's war merit increased greatly and officially entered the top ten, a momentum of rapid progress.

As for the top three bases in the war merit list, the total war merit is still higher.

But the growth rate has already shown a decline.

Su Yunfei's eyes were fierce.

Now, the base of zombie rats is large enough, and he doesn't need to produce them anymore.

So...

Let's start the official rat extermination!
