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

The rat tide was coming from the west.

Su Yunfei was flying towards the east in the air about 100 meters.

The night wind blew on his face, which was a bit cutting.

His speed reached more than 500 kilometers per hour.

Large birds with strong aggressiveness, such as night owls, immediately flew towards him, but they could not catch up, so they had to give up.

Su Yunfei observed the rats below.

After a while.

Su Yunfei found a clue.

I saw that there was a building with more than 20 floors in the east, presenting a strange scene-

At the front door of the building, rats from all directions ran in;

At the back door of the building, thousands of rats rushed out together and flowed towards the west.

It looked like all the rats around gathered here and then moved collectively.

"There must be something in the building!"

Su Yunfei frowned, thought for a moment, and reduced his flying speed.

He flew a little lower and threw a grenade directly into the front door of the building!

It was thrown very accurately.

The glass door on the first floor of the building had already been broken.

The grenade went straight into the lobby on the first floor.

There was a loud bang.

Some glass windows on the second and third floors were shattered.

The air wave even blew away the densely packed rats.

Many rats died from the falling glass fragments.

In an instant, the rats were in chaos!

The rats turned their eyes and looked around vigilantly.

Su Yunfei watched the changes quietly.

Not long after, as expected, several huge mutant rats rushed out!

One golden, one silver, and two blue ones.

After searching, they also saw Su Yunfei flying in the night sky.

At this time, Su Yunfei was like a big bird, and he was a natural enemy in the eyes of the rats.

The mutant rats immediately screamed as a warning, arched their bodies, and took a fighting posture.

"Hehe~"

Su Yunfei moved his mind and flew over like an arrow from a string.

Flying at a low altitude, he passed directly over the head of a mutant rat.

At the same time, a red light flashed in his hand, and a flame knife appeared!

The knife light fell down, leaving a trail of blazing red flames in the air.

Su Yunfei knew the weaknesses of these mutant rats very well.

Especially in the air-to-ground situation.

These rats were fearless and rushed directly, but they just met the blade.

In the blink of an eye.

The two blue-haired rats were killed, with smoke coming out of their bodies and their hair being burnt.

Seeing this, the silver-haired rat and the golden-haired rat became even more angry and rushed over together.

Su Yunfei turned nimbly and flew high.

Swinging the knife, slashing down, leaving a long knife mark.

The frequency of swinging the flame knife was too fast, and the fire element was so strong that it actually triggered fireballs!

The silver-haired rat and the golden-haired rat did not last long and died.

Without thinking, Su Yunfei quickly collected the bodies of the four mutant rats.

"If I buy another green-haired rat, I can complete the five-star Wolf King gift!"

He was looking forward to the five-star gift because he could get a good thing like a flying prop.

Just as he put the mutant rat away, a bull-sized figure rushed out of the building at an astonishing speed!

Su Yunfei immediately flew high and looked at the monster below with lingering fear.

It's so big, but it's also a rat!

This rat is almost 1.8 meters tall!

"Weakness Insight!"

[Level 10 Mutated King Kong Rat]

A half-step leader-level mutant, with better size, defense, strength and other aspects.

HP: 6800

Strength: 688

Agility: 543

…

Skill 1: Rough Charge

Skill 2: Charged Jump

Skill 3: Golden Storm

Skill 4: …

…

B-level Talent: Diamond Body

B-level Talent: Metal Eater

…

Weakness: Its Diamond Body is not yet fully developed, and its resistance to various elements is extremely low!

…

Su Yunfei was shocked: "Monsters actually have talents? And two?"

This is really the first time I've seen it!

Come to think of it, the rat tribe can also have geniuses.

He immediately prepared for battle, hovering in the air, thinking about how to kill this guy.

This level 10 mutant diamond rat in front of him is the most powerful monster he has faced so far!

Half-step leader level!

Luckily, if this guy is a leader level, his A-level talent weakness insight will not be useful.

Su Yunfei guessed: "Could it be that they made such a big noise in order to advance to the leader level?"

Thinking this way, Su Yunfei threw a stone at the mutant King Kong rat to test it.

After the rat tide occurred, he also picked up some stones in case of emergency.

The mutant King Kong rat was extremely fast, and it raised its claws and smashed the stone.

It narrowed its eyes coldly and looked at Su Yunfei in the air, with an angry and disdainful expression.Su Yunfei saw its little eyes and sneered: "What are you looking at? If you have the guts, don't run away!"

What he is most worried about now is that the mutant King Kong rat will run back to the building to hide while fighting.

There are so many corners in the building, which is very troublesome.

At this moment, Su Yunfei did not hesitate and used multiple methods at the same time.

While waving the flame knife to chop up.

"Virus Overlord!"

"Nightmare Abyss!"

The two skills were also used at the same time.

His figure was even more flexible, like a butterfly flying through flowers, erratic.

He was less than three meters away from the ground, very close to the King Kong rat.

But the mutant King Kong rat below, no matter it jumped up suddenly or spit out golden wind energy, did not even touch the corner of Su Yunfei's clothes.

An overly flexible air unit is a dimensionality reduction attack on the ground!

Su Yunfei was full of martial virtues and suddenly floated behind the mutant King Kong rat.

He raised the flame knife and stabbed at a chrysanthemum quickly:

"Secret Secret! Thousand Years of Killing!"

The mutant King Kong rat had noticed it, but still couldn't dodge it.

"Squeak, squeak, squeak!"

It screamed wildly, its eyes red, and was completely angry.

Not only was there blood flowing around the fragile chrysanthemum, but it was also damaged by the fire system, as if it was on fire, and it continued to hurt.

The mutant King Kong rat jumped up and down on the spot and began to go crazy.

He used all kinds of skills randomly.

And like an enraged bull, he rushed towards Su Yunfei.

This was also because Su Yunfei had abundant martial virtues and repeatedly stopped not far from it, giving it the illusion that it could kill him in one hit.

But when the mutant King Kong rat rushed over, it flew up.

The mutant King Kong rat missed three times and directly broke a stone pillar in front of the building!

This force should not be underestimated.

Su Yunfei was still releasing the nightmare abyss.

Now it is a master-level nightmare secret technique, which is also useful for level 10 boss monsters.

The mutant King Kong rat became more and more crazy, completely lost his mind, and didn't even think about escaping.

"Bang bang!"

One knife went down.

Two long and sharp rat teeth were broken and flew out.

"Squeak squeak squeak!"

The mutant King Kong rat howled wildly.

Su Yunfei saw that it was so pitiful.

So he decided to give it a small gift.

Quickly, he stuffed a grenade and a molotov cocktail into its mouth.

There was a loud bang.

Black smoke came out of the King Kong rat's mouth, and blood flowed.

There was also a flame burning.

It twisted its body and began its final madness.

Su Yunfei was hanging in a safe position in the air and stopped moving.

The mutant King Kong rat was now full of continuous damage.

In less than three minutes.

King Kong rat, die!

Several system announcements resounded through everyone's mind at the base:

[Safe Base No. 3418, Su Yunfei was the first to kill the half-step leader-level monster · Level 10 Mutated King Kong Rat, the reward has been hidden! ]

[Safe Base No. 3418, Su Yunfei has killed the leader of this rat tide, and no new rat swarms will be generated! ]
