As time went by, hundreds of survivors kept cautiously facing out with guns. △ however, the zombie never appeared

However, at this time, on one section of the protective wall, a survivor in charge of guarding suddenly put down his telescope.

To be exact, it fell

He stared blankly at the end of the street, and this abnormal reaction caused his companion to wonder, "what's the matter? What's the matter?"

With that, the companion turned his eyes to the telescope under his feet. But before he picked up the telescope, he found that this thing was no longer needed

What the guard saw had appeared within the scope of his naked eyes.

The red air spreading like poison gas, and a large number of monsters shrouded in it

Some of them fly in the sky, while others climb on tall buildings

"What is this?" He straightened up and murmured.

The guard finally gave a sad cry: "enemy attack!!!"

Ling Mo and others finally know what they are waiting for.

It's not the zombie of central city, nor the Spider Queen, but a new... Infection.

Before the arrival of those monsters, the red air had swept the miracle base.

"Ah!" As soon as a survivor inhaled a little, he suddenly screamed, shook off his gun and fell to the ground convulsively.

But no one cares about him... Because people around him also have the same symptoms.

"Come on, cover your mouth and nose!" Cried Lucy.

Su qianrou's face was pale: "it's useless. The gas will drill into the pores."

She pointed to a power on the wall. The man had already covered his mouth and nose. But he still fell down at the moment when he came into contact with the red air.

"Ga!"

A zombie hovering in the sky suddenly screamed. Then he swooped down on a survivor on the wall.

"Poof!"

It quietly appeared a blood hole in its forehead, and then fell down.

"The first area lost contact..."

"The third area lost contact..."

"There is no news in the fifth area..."

Ling Mo turned his head and looked at the crowd and made a decision: "let's go back to the building."

At this time, a fierce battle suddenly came from the rear of these monsters.

Ling Mo looked back and suddenly saw countless extremely fast tentacles in the distance.

One by one, the zombies suddenly rushed out of their hiding place and threw those monsters to the ground like the strongest hunter.

The blood immediately splashed everywhere, and the monsters turned their attention from the direction of the miracle base to those mutated zombies.

"Are they helping us?" Xu Shuhan said in astonishment.

Xia Na stared in that direction with complicated eyes, shook her head and said, "No. they are hunting."

"Take this opportunity to withdraw, quick!" Ling Mo suddenly recovered and shouted.

The survivors in panic and confusion suddenly woke up and took action.

The protective wall of miracle base fell

A few minutes later, Ling Mo and others returned to the experimental building.

"The command building is also full of people, but most of them have been infected."

"So is dormitory No. 1."

"So is the warehouse!"

The report was constantly passed to Su qianrou through the communicator, and then she conveyed it to Ling Mo word for word.

However, what made her feel a little incomprehensible was that although the situation had changed significantly, Ling Mo seemed to be only surprised. There is no despair.

"Ling Mo, this may really be the last of mankind. Do you remember when the virus infection first appeared? At that time, there were billions of human beings. There were tens of millions of people in X city. But in the end, there were only thousands of people living beside me." Su qianrou whispered that she was also calm, but not because she didn't despair

In fact, when she saw the red air, she was already desperate, but she was still living by inertia.

After struggling for hundreds of days and nights on the line of life and death, compared with ordinary people at the beginning, they will always learn something.

"How are those infected?" Ling Mo asked.

When the red air appeared, he was also stunned, but then he figured out a lot of things.

Why did the actions of the zombies in the central city change, and what was the "enemy" that Lao Zheng said could not resist.

In fact, the answer is very simple, virus upgrade.

The virus has been upgrading, but it was in the bodies of zombies before, but when this upgrading method cannot meet the needs of the virus itself, it will return to the original upgrading method: full outbreak through the air. This is easier to understand when Ling Mo feels it through female zombies.

The zombies in the central city served as a medium for the full outbreak of the virus again.

If he hadn't manipulated Xiaobai to disrupt the "plan" of the virus, there would be no buffer period now.

The virus will spread to the whole city in an instant like a nuclear bomb explosion, and all human beings and zombies will be infected.

However, since it is an infection, it is not necessarily fatal.

Most importantly, Ling Mo has experienced the feeling of being reinfected through Xiaobai.

But the real key is that Lao Zheng said he was a variable. Why?

Ye Lian just said a sentence in his consciousness network: "you are between zombies and humans."

He is an anomaly after the last virus outbreak

So it's not the zombie in central city who wants to get rid of him, but the virus who wants to get rid of him. When the virus wanted to upgrade in an all-round way, it felt that it was a strange creature existing in the "body". It's like feeling sick.

But the virus does not have the ability of thinking, and its intention can only be realized through the carrier. However, the carrier chosen by it can't implement its idea well, which is why only Lao Zheng and others are sent to solve Ling mo.

Of course, it's only Ling Mo's guess about the last point, because judging from what the Spider Queen did, the zombie was not completely unable to resist the virus. And Zombies also have a rebellious mentality.

To some extent, the human survivors at this time are actually on the same front with zombies like the Spider Queen.

"Infected person?" Su qianrou was stunned when she heard Ling Mo's question, but she answered responsibly, "many of them are struggling desperately."

"So are they confused? Or, are they losing their ability to think?" Ling Mo asked again.

Lin luanqiu stood up and shook his head. "No, I have asked them some questions. Although there is an obvious tendency of violence, they are very sober and know how to restrain."

Hearing this, Su qianrou's expression suddenly changed, and her eyes also regained some expression: "Ling Mo, you mean..."

"The virus in human body is escalating." Lucy answered for Lingmo.

Ling Mo nodded: "yes, upgrading is not the same as mutating from a human into a zombie, because there is a virus in the human body."

Lucy nodded approvingly and said, "for example, if the virus in zombies is type A, then the virus in humans is type B. Ling Mo is right."

"Well, infection is to upgrade the type A virus in zombies to a+1, or even +2, and humans are also upgraded from B to b+1, b+2. That is to say, there may be some changes, but it is different from when they were infected and became zombies." Ling Mo said.

After he said this, Su qianrou immediately held her hand and walked back and forth, and kept saying, "so it is... So it is... So long as they can survive this period of time, human beings will not necessarily perish..."

"No, I think you're wrong." Wang Lin, who had not spoken since Lao Zheng's death, suddenly raised his head and said, "after the virus upgrades again, we are no longer human..."

Ling Mo's heart moved after hearing this sentence... He is the only variable.

And Zombies? Are there variables in zombies?

Somehow, Ling Mo suddenly turns his head and looks at Ye Lian standing in front of the window. (to be continued, please search for better novels and faster updates!
