Along the way, the alien creatures chased after each other, and they were completely in a situation where they couldn't kill Mo Fei and the others and didn't look back.

After the Dark Superman was at the end, he was subjected to the highest attack, and Mo Fei had already rushed to the front after just breaking the gap, and he had not received much attack at all.

"Damn it." Dark Superman scolded as he looked at the alien creatures.

The xenomorphs who were in hot pursuit were killed by Dark Superman one after another, but these xenomorphs still chased after everyone's team, and did not stop at all because Dark Superman killed a large number of their companions.

Mo Fei rushed into the city first, and immediately rushed towards a building in the city, he wanted to use this building to defend against the alien creatures in the rear.

After Dark Superman was the last to rush into the center of the city and break away from the residential area, Dark Superman suddenly felt no pressure behind him, and many alien creatures stopped at once.

"They are afraid to enter the center of the city." Tony also noticed the situation and shouted at the crowd.

As soon as Mo Fei rushed into the building, he immediately heard Tony's shout and stopped, looking at the group of alien creatures on the edge of the city center, Mo Fei frowned slightly.

What is there in the heart of the city that keeps them from entering? There was nothing stopping them, and looking at them, it was as if they were blocked by an invisible wall.

"Did you find anything? Why are they afraid to enter the city center? Mo Fei asked the crowd.

Both Tony and Cyborg shook their heads, if something suspicious was found, the system on them would have already sounded the alarm. Of course, their technology is much worse than this space battleship, even if there is something suspicious. Neither will they find out.

"I don't feel anything." Dark Superman shook his head and said.

Others were even less likely to feel anything, though it was strange why none of these alien creatures dared to enter the center of the city. But at least they're safe now.

"I think there must be something we don't know about, so be careful, everybody." Mo Fei said to everyone.

There are all kinds of shops in the center of the city, and now Mo Fei and the others have entered a building that Mo Fei selected before, just on the edge of the city center, although it is not the largest and tallest building in the city center, but this building is a fairly tall one in the vicinity.

"There's still food here, I don't know if I can eat it." Tony said after discovering the cold room.

There are several floors in the building that are dedicated to dining, so Tony pulls out of the cold room to look at the food in the cold room. Tony didn't dare to take it lightly.

"If you dare to eat, I can make it for you." Natasha smiled at Tony.

Although these pieces of meat are all pieces of meat that have been processed, everyone does not dare to try them easily, who knows what kind of meat it is.

At Murphy's suggestion, everyone went to the rooftop to rest, observing everything around them, the entire city center was silent, except for the edges, a faint sound could be heard, it was the sound of alien creatures struggling to enter the center of the city.

"Why can't these things get in?" Tony said, pointing to the alien creature below.

"Who knows. These things are weak, but they are just a huge number. Dark Superman said, glancing at the alien creature.

"What are we going to do next?" Captain Steve asked the crowd.

"Captain, I feel like my stamina is declining." A S.H.I.E.L.D. agent said suddenly.

Captain Steve immediately looked over and noticed that the S.H.I.E.L.D. agent had a somewhat bad face. It makes people feel like he's sick.

"What's wrong? Hit by a chemical or biological weapon? Mo Fei suddenly stood up and said.

They hadn't been attacked by any biological weapons just now, but now someone had suddenly been attacked by a biological weapon, albeit very weakly. But after all, it was a trick.

"He really looks like he's been hit by a biological weapon and caused a disease." Seeing that the S.H.I.E.L.D. agent was pale, and at the same time he didn't have much strength. The nerves of the crowd were tensed.

Silently let a S.H.I.E.L.D. agent get hit, and this kind of attack is really a bit terrifying. But they didn't find out when they were tricked, so they had to find out clearly, otherwise they didn't know how they really died.

"Is that what it is?" Tony said, pointing to the alien creatures under the building.

After they came here, they probably touched these alien creatures, and if they had everything else, then everyone should have been hit by biological and chemical weapons, and they were so weak, completely different from the hall weapons that everyone encountered before.

"I have a suspicion, did these alien creatures we killed carry some kind of virus, and then after entering the city center, these viruses are activated?" Mo Fei said to everyone.

Viruses or something, it's not easy to get close to Mo Fei, under the protection of the body protector Jian Gang, viruses can be strangled into ashes, so Mo Fei is not worried that he will be infected by the virus.

Dark Superman didn't feel anything, and his super physique made him not afraid of any viruses at all, so he didn't notice anything.

And when everyone examined themselves, the S.H.I.E.L.D. agents turned pale one after another, and they all felt weak and powerless, and there was no way to move forward like this.

"They're done." Dark Green Arrow shook his head and said.

In this environment, they can't be rescued at all, so they have to wait for death, and Dark Green Arrow is also wondering, how can his body not be poisoned?

"Let's go find a building like the Institute." Mo Fei said to everyone.

The S.H.I.E.L.D. agents were the first to be recruited, which can show that this is a virus invading, and it is also the kind of chronic effect, although their physique may be stronger than that of S.H.I.E.L.D. agents, but if they stay here for a long time, they may not be able to escape such a fate.

Is there a research institute in the center of the city, as long as Mo Fei and Dark Superman fly into the sky to find it, of course, it may be hidden underground, but Mo Fei and the two still fly up to find it.

Tony and DarkCyborg immediately ran to a place where there was a computer, looking for a computer that could be used, and then invading to find a way to control the intelligent system of the space battleship.

Murphy and Dark Superman searched quickly, and they didn't find any research institutes, only found one of the tallest buildings in the center of the city that was official, so they were going to ask Tony and the others to come over to take a look at the situation. (To be continued......)
