Walking through the streets of New York, Zhang Yu constantly perceives the surrounding situation, looking for clues of people who can survive this apocalyptic crisis.

The pollution is spreading faster than he imagined, the Avengers are the first, but it will never be the last, at this moment, the vast majority of ordinary people have been eaten and wiped clean, and turned into wreckage everywhere.

Even if some of them are not eaten, they have already climbed back up and become one of the zombies, and continue to spread the pollution to more people.

It was under these circumstances that Zhang Yu's plan to find the survivors became extremely difficult.

(No movement of pollution sources has been detected, or rather, there are pollution sources everywhere, and every pollution carrier who has turned into a zombie is a part of the pollution, which will interfere with my detection)

As early as the beginning, Zhang Yu tried to let Miss Time use the time controller to find the main source of the release of this pollution, but now, this matter is obviously not so easy.

"That's the problem, the zombie sentry has infected the entire Avengers, but what about him now?"

Zhang Yu's eyes narrowed, and his fists gradually clenched.

In this universe, this universe infected with the zombie virus, everything is generated by the arrival of the zombie sentinel, the key is that the zombie sentinel is not a person from this universe, and this universe does not even have a sentinel.

Sentinel, whose real name is Robert Reynolds, is an addict in other universes who, during a drug theft, inadvertently breaks into a laboratory and drinks a mysterious potion, giving him great powers.

The power of that potion was enough for him to contain the power of millions of stars in his body, which was also the source of his unrivaled power.

While awakening the invincible power, Robert also unleashed another of the strangest beings in the universe - nothingness.

Some people say that Nothingness is actually another dark personality of the Sentinel, but no matter what, no one can really determine the origin of this thing, and even Doctor Strange can only reluctantly seal it away without being able to completely solve it.

From this point, it can also be seen that the source of the sentinel's power is not the so-called 'potion', and the void is not just his dark personality, but a more treacherous existence.

But in this universe, due to the relationship between timeline and era, Sentinels have not yet been born, and there is no way to talk about nothingness.

The zombie sentinel that came from the pink lightning and carried countless pollution to this place was actually a sentinel from another universe.

And the reason why the zombie crisis broke out in that universe is not for any other reason, it is precisely because the zombies of this universe have found a way to travel through the universe and spread the pollution there.

It was in that world that the Sentinels were contaminated by the Green Hulk, transformed into the world's most powerful zombies, and tried to detonate the millions of stellar energy in their bodies, blowing a hole in the multiverse's reality barrier to spread more pollution.

At this critical moment, the observer who had been hiding here finally couldn't help but take action, and he teleported the zombie sentry back to the beginning of this universe, and with the arrival of pink lightning, a perfect closed mouth cycle began

On the surface, this trouble has finally been solved, but in fact, a new problem has arisen.

That's the beginning and end of everything, the zombie sentinel who is the first infected and the last infected at the same time, where did he go at this moment?

After successfully infecting the Avengers of this world, he did not expand the scope of the pollution source, nor did he participate in the subsequent plot, and even in the subsequent plot, the zombie sentinel never appeared.

It was as if he had disappeared into thin air, as if he had come to this world only to spread pollution.

"So. Where would you be now? ”

Zhang Yu raised his arm, and the black crow suddenly flew over as if it had been summoned, and landed firmly on Zhang Yu's elbow.

A faint blue light emanated from the crow's pupils, and some indescribable energy diffused out, and soon connected with Zhang Yu's magic.

At the moment when the two energies were entangled, Zhang Yu immediately received the shared vision brought by the observer's eye, and the whole world and even the entire timeline became transparent at this moment, like a book for Zhang Yu to read freely.

Generally speaking, from the perspective of an observer, Zhang Yu can see everything that happens in this universe, whether it is the past or the future, even the path of a fine piece of dust cannot escape Zhang Yu's eyes.

But at this moment, a special feeling appeared, as if a thick fog had fallen in the middle of the night, and all the scenes about this universe began to become blurred.

"Wow-wow——!"

The crow opened its beak and let out a piercing scream, then kept fiddling its head with its wings, trying to clear the invisible obscurity.

"Sure enough, this timeline is also tainted"

Zhang Yu frowned, he knew that the cycle had begun at this time, the zombie universe and the Z universe had been completely linked, and both times were all covered by pollution, and it was precisely because of this that the power of the observer's eye was affected.

(No wonder I've been disturbed and so on, if the timeline is contaminated, then the source of the contamination could be at any point in time, and it will be even more difficult for us to find it)

"No, I can feel that the zombie sentry hasn't left 'here' yet, so much stellar energy is not so easy to hide, he must be hiding somewhere here, but I can't be sure yet"

Zhang Yu touched his chin, and suddenly, an explosion in the distance caught his attention.

Two blocks away, a violent explosion sounded, and Zhang Yu could feel the ground tremble slightly, and the surrounding glass was shattered.

Looking at the smoke coming out of there, Zhang Yu looked a little puzzled.

Although I don't know who is fighting the zombies, Zhang Yu doesn't mind going over to take a look, maybe he can find other interesting gains.

——

Above the Helicarrier.

In order to allow Reed Richards to better research the antidote, Nick Fury specially prepared a laboratory for him.

In this laboratory, it can be said that all the cutting-edge technology of S.H.I.E.L.D. gathers here, and not only that, but any equipment that Reed needs, Nick Fury has done his best to help him find it.

If it was before, then S.H.I.E.L.D. would have had some trouble in acting, but now it is different, anyway, the world is in chaos now, the US military is difficult to protect itself, and the high-tech equipment in the hands of those various forces has all become ownerless.

Wearing quantum glasses, Reed Richards carefully observed the zombie test subject in front of him.

This is an ordinary person infected with the zombie virus, with a group of superheroes in charge, it didn't take much effort to capture him, and Reed Richards used several potions to barely control his movements.

It's not difficult to kill a zombie, especially this kind of ordinary infected, but the dead infected person is not necessary for Reed Richards, and if he wants to find the 'antidote', he must conduct live experiments.

"How's it going, Reed, did you find anything?"

Seeing that Reed Richards had been staring at this zombie for a long time, the stone man couldn't help but ask.

Hearing this, Reid Richards came back to his senses, he wiped the sweat from his forehead, and shook his head slightly.

"The origin of these viruses is very strange for me. Can't"

Rubbing his temples, Reed Richards' eyes brightened a little.

"I couldn't determine the exact form of these viruses, and at first I thought that people infected with these viruses would be transmitted through the bloodstream and then attack the brain and destroy the nerves in the brain, just like in the movie."

"Go on."

Susan, the Invisible Woman, also walked over, curiously waiting for Reed Richards to continue.

Reid Richards didn't sell it, he frowned and explained solemnly.

"But that's not right, this virus is even more weird than I thought, it expands at a rapid rate after entering the bloodstream, and continues to multiply and replace, eventually creating a completely different set of cells and nerves."

"So what?" The stone man didn't understand what he was trying to express.

"Ever heard of the 'Theseus Ship Paradox'?"

Reed Richards raised his head and looked at the other Fantastic Three, he pointed to the zombie test subject in front of him, and said seriously word by word.

"At first, it was just a simulation of cells, but slowly, the mimicry of the virus will allow it to evolve the ability to mimic more matter, and when everything in a person's body is replaced, it will even simulate your personality and soul.

And at that time, will you still be a ling? ”

Hearing Reed Richards say such terrifying words in a flat tone, several people present broke out in a cold sweat, and their expressions became ugly.

"So you mean that this virus is eating away at life and replacing it, just like the Skrulls, inheriting all the thoughts and memories of the infected, but not the original him anymore?" Susan frowned.

"That's right! That's it, and the special elements in the virus will make people hungry and want to devour everything in front of them. ”

Reid Richards shook his head slightly.

"This, this is not something that science can solve, I want to tell Nick Fury about this situation, outside, those people outside can no longer be regarded as 'people', they have no possibility of being saved at all!"

The entrance to the laboratory.

Several S.H.I.E.L.D. agents who were standing guard looked at Reed Richards, who was talking to himself alone in the room, from the exterior glass, and looked at each other a little helplessly.

"Mister Fantastic is speaking a language we don't understand again, and I assure you, it's definitely not the language of any country on earth."

The other agent just shrugged his shoulders.

"Either they are the smartest people in the world, and if they can make you understand, then you won't have to be on duty here, don't talk about this, until the other heroes come back, we will protect Mr. Fantastic for the antidote research."
