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

…………………

Since leaving the highway, Su Yunfei's speed has been greatly reduced.

From 4000 meters to 4500 meters.

Because it was not a straight line and he did not ride a bike again, it took more than two hours to open this section of the map.

All the time was spent on rushing and finding the road.

Su Yunfei felt very fucked up.

But there was no way, the road had to be walked and the map had to be opened!

He didn't know where the map of the 3427 base was opened.

According to the big mouth on the opposite side, it is very likely to be close to 5000 meters!

In any case, Su Yunfei must open the 5000-meter node today.

Fortunately.

He encountered many monsters along the way.

After he killed and extracted them all.

His accumulated energy has now reached more than 3000 points.

It is equivalent to almost reaching level 5.

...

Soon, it was more than three o'clock in the afternoon.

Outside the 3418 security base, there were monster-killing teams everywhere.

After the fight, the monster corpses have to be collected.

Collect a few and then trade them to Su Yunfei.

Su Yunfei has already put some supplies on the trading platform.

Since the afternoon, corpses have been received one after another.

He did not care much and would do batch operations when there are more.

At this time.

Su Yunfei frowned and was in the ruins of the building.

Here, it seems to be in the downtown area, with dense buildings.

After the building collapsed, the road was also severely damaged.

There is actually a river nearby, which seriously hinders traffic.

What's even more outrageous is.

Su Yunfei felt that the air seemed to become sticky and heavy, very stuffy, and made it difficult for him to breathe.

The oxygen content is relatively low, and there is an inexplicable resistance in the air.

The thick gray fog rolled, exuding a cold breath, compressing his field of vision to less than ten meters.

Su Yunfei slowly looked around and took a deep breath-

From here on, it can be said that the difficulty has increased several times compared to before!

He didn't expect that it would be so difficult later.

"If I continue to move forward, I will most likely not be able to return to the base today!"

I have to spend the night outside!

Su Yunfei glanced at his attribute panel.

Today, he received another batch of attribute points as a teaching reward.

His current strength attribute has reached 650 points!

His combat power has also increased to more than 2,500.

Such strength is enough to kill a level 4 elite zombie in seconds.

If he really can't return to the base, he should be able to protect himself at night...

Su Yunfei's footsteps were light as he climbed over the ruins of the building.

There was a dead end ahead, and half of the building had collapsed.

Crack, crack, crack!

Su Yunfei ran a few steps quickly and stepped directly onto the wall. With the help of the kick, his body soared two or three meters into the air.

Then, he used one hand to gain leverage from the corner of the wall and climbed onto the collapsed building, walking directly from above.

But at this moment.

"Hua hua hua!"

Bean-sized raindrops fell from the sky.

The yellow-green rain had an unpleasant sour smell.

Su Yunfei's expression changed.

Then he heard the system announcement:

[Base 3418, the weather suddenly changed within 5 kilometers, and acid rain fell. Please find shelter as soon as possible! ]

The chat channel of the base was immediately filled with curses:

"Fuck, this rain is poisonous and smelly, and the skin will swell up when it touches it!"

"Damn, it's so cool to upgrade!"

"Oh my god! Could it be an undercover sent by the other side?"

The acid rain fell, and Su Yunfei was fully protected and had the talent of virus master, so he was immune to all poisons. In fact, he didn't feel anything.

But under the erosion of rain, the buildings and roads became extremely slippery, and the difficulty of moving increased.

Liu Shan and others had found a building to hide in.

Liu Shan privately chatted with Su Yunfei and said, "Boss, what's going on over there? Hurry up and hide from the rain."

Lin Yongnan also worriedly said, "It's getting dark, and this is all. Boss, you're the one who's working the hardest today. Can you come back tonight?"

Su Yunfei replied to the two of them, "It depends. Maybe I won't go back."

Liu Shan immediately advised, "It's too dangerous to stay out overnight. Just do your best. As long as you have the green mountains, you won't be afraid of running out of firewood!"

The base was also full of similar pessimistic views.

It was too unlucky. If it really doesn't work, you will lose in a full PK.

Su Yunfei said lightly, "Do your best. I'm busy."

Originally, he was sure to win, but he was helpless when he encountered such an emergency.

Su Yunfei braved the acid rain and advanced a distance.

The fog was getting thicker and thicker, and it was almost impossible to see even five meters in front of him.

The temperature was also dropping rapidly!

He glanced at the map and found that the 5,000-meter node was not far away.

The system prompts:

[It is raining heavily now, it is recommended to take shelter. ]

Su Yunfei followedHe asked, "When will the rain stop!"

[The rain is expected to stop within half an hour! ]

"Okay."

A few minutes later.

Su Yunfei walked into a low-rise house.

He acted like lightning and solved the four little zombies here.

The house was dark and gloomy. Su Yunfei did not intend to go deep into it. He just took shelter in the main room.

He had seen many ordinary houses like this along the way. There were no supplies at all.

At this moment, what he lacked most was time!

"Hehehehe..."

Suddenly.

A strange laugh came from nowhere.

A black shadow, floating and flickering, quickly came nearby.

Su Yunfei shuddered all over, felt cold all over, and turned around like lightning.

But at this moment, his head suddenly felt dizzy.

There was a vague feeling like dreaming!

System prompt:

[Hidden task: Trial of the Strong ① has been opened! 】

This reminder brought Su Yunfei back to his senses.

His heart was as clear as a mirror-

It turned out that the black shadow just now was the hidden mission target!

However.

His spirit began to dream uncontrollably and sank into the dream.

In the dream.

Su Yunfei was still an ordinary college student, living a fulfilling campus life.

But suddenly, the buddies who played football together turned into stiff green zombies, baring their teeth and rushing towards him...

Su Yunfei's fighting instinct emerged, and he wanted to beat the zombies violently.

But he was suppressed by the dream and began to run away.

Along the way, he saw all kinds of tragic situations of zombies biting people.

Blood, pieces of meat...

More and more realistic...

...

...

Base chat channel.

At this time, almost everyone either found shelter or returned to the base.

An acid rain made everyone very anxious.

"Damn, it's already past four o'clock, and it's almost six o'clock!"

"Oh, I'm afraid we're going to lose. I'm unlucky, so unlucky!"

There was a lot of complaints.

Liu Shan and others had no good solution.

Suddenly.

Someone was shocked and said, "Why is Su's avatar gray?!"

Everyone in the base was shocked.

Everyone saw that Su Yunfei's avatar was really gray, and it became black and white!

No one spoke for a long time.

The chill in the rain outside had spread to their hearts.

Everyone felt a chill of astonishment and despair in their hearts!

After more than ten seconds.

Someone asked anxiously:

"Boss, isn't it...something happened?"

Others took over:

"Boss, boss, say something, don't scare us!"

"What's going on? I don't believe it..."

The five members of the Wentian team looked at each other, their faces were very ugly.

They had talked to Su Yunfei a few minutes ago.

An accident happened now?
