Reborn in the end of the world, I scavenged in the empty city and bought for free

Not only did the mutants have slight changes in appearance, but most importantly, they seemed to have initially formed organs that simulated humans.

Perhaps the so-called zombies after the end of the world in the previous life were not mutated humans, but "zombie-like" evolved from mutant species, so their speed and mutation are higher than those of ordinary mutant beasts.

The most important factor that causes the mutants here to evolve rapidly should be related to the black fog in front of them.

I squinted my eyes and saw that the black fog gradually dissipated at around 1:30 in the afternoon, and the tapeworms seemed to hide in the corners or in the moist soil.

Around seven o'clock in the evening, after dinner, Gu Tongwan ran to the road outside the community to observe. Sure enough, he saw that black shadows began to move vaguely in the place where the black fog originally appeared.

The length of time between day and night in the empty city is similar to that in the normal world in summer. It gets light around 6:30 in the morning, and the whole city is shrouded in darkness after 7:00 in the evening. Although there is no sun or moon in the sky, the day and night are very distinct.

Although the black fog appeared briefly at noon, there was no large-scale activity for the time being, and it did not actively attack things around it. This means that the black fog's activities were restricted during the day, and they were only most active at night. During this time, the tapeworms in the black fog would also reproduce on a large scale.

Just as the black fog gradually expanded and turned into a huge monster, suddenly a strange panting sound came from several directions on the street corners.

Then, more than a dozen black shadows were seen rushing into the black fog, and in the black fog there was a sound similar to chewing. The sound came out densely from inside, making people's scalp numb.

Could it be that these mutants evolved so quickly thanks to the tapeworms in the black fog?

No matter how she thought about it, it was useless. However, a voice in her heart told her that at least she must not allow these mutants to successfully evolve tonight, otherwise the number of mutants in the empty city would increase in the future, which would bring her great trouble.

Thinking of this, Gu Tongwan took out several grenades from the space, then ran forward quickly, blowing a whistle.

This was an order to fight. Aoao and Tutu understood it immediately and began to encircle the enemy from two different directions. During this process, light blue lightning was brewing on their bodies.

Gu Tongwan pulled two grenades and threw them into the black fog, then dodged and hid behind an abandoned pickup truck. Two deafening explosions were heard, followed by concave and convex lightning. For a moment, the air was filled with the smell of grenade powder and the burnt smell of lightning.

Heart-wrenching screams began to rang out one after another, and the black fog continued to weaken, and the remains of limbs scattered on the ground could be vaguely seen.

Gu Tongwan chose the right time and rushed into the dark room. She was wearing a special tights that could wrap around the skin well to prevent the tapeworms in the black fog from invading the body. She also wore a protective mask and night vision goggles on her face.

After entering, I saw the remains of the mutants scattered in different corners. Some mutants that had not yet died were crawling on the ground, and their skin began to rapidly turn gray and shrunken. It was visible to the naked eye that their bodies were much thinner than before.

It seems that her guess was correct. These mutants must have evolved rapidly by relying on the parasitic tapeworms in their bodies.

There were eleven or twelve mutants in total. Because the attack was sudden, these mutants, who were originally enjoying their "evolution", were caught off guard.

Gu Tongwan took out the crystal core powder that he had prepared in advance from his pocket and poured some of it on the mutants. Although the mutants howled for a while, the corrosion rate of the crystal core powder on them was greatly reduced.

It seems that the evolved mutants have increased their resistance to crystal core powder. However, if plants in the apocalypse are also constantly evolving, the extracted crystal core powder should be more corrosive to the mutants.

Unfortunately, after being in the empty city for a year and a half, there was almost no grass growing in the entire city. She didn't see anything that could be called a plant at all. She also tried to transplant the black soil in the space to the soil outside, but no matter whether it was the seeds bought from the system mall or the batch of seeds bought before the end of the world, the soil did not move at all. She also tried to take out the newly emerged fruit sprouts from the soil, but after only five minutes, the sprouts gradually withered and died.

After waiting for about ten minutes, the black fog gradually dissipated. Gu Tongwan squatted down and put some tapeworms that were still wriggling on the ground into a glass cup, intending to go back and do some experiments.

At this moment, the worm suddenly opened its mouth, its entire mouth was covered with dense fangs, and it spit out a lot of yellowish-brown liquid.
