This silver-black mutant rat is rather strange, and its body is glued with a lot of steel bars, iron plates, iron tables and other various items.

The silver-black mutant rat gave Liu Wen a strange feeling, it was like a magnet, absorbing a lot of iron objects on its body.

Originally, this silver-black mutant rat had been wrapped in these iron objects, and he couldn't even see clearly.

When it first came out, Liu Wen hadn't recognized it, it was a mutant rat, and the whole thing was a monster composed of steel waste.

When the silver-black mutant rat came out of the cave, it was just in time for the zombies to rush to the inner city of the giant fortress and start slaughtering the mutant rats.

Liu Wen in the sky clearly saw that the silver-black mutant rat roared, and all kinds of iron metal objects stuck to its body shot out directly.

Because of its great strength, these various ferrous metals shot out of it by the silver-black mutant rats directly killed a large number of zombies around it in seconds.

Even, Liu Wen saw a corpse general, whose head was cut off by an iron plate.

Because Liu Wen has the ability to solidify metal, with the improvement of his ability, Liu Wen can no longer look down on ordinary iron objects.

Before the end of the world, the titanium alloy with a relatively hard texture is not even as good as a first-order tenth-level person with metal solidification, and the material of the permanently solidified items is not as good as in today's last days.

At this time, this ordinary iron plate, which was an iron plate before the end of the world, actually killed a corpse general in the hands of this silver-black mutant rat.

Seeing this scene, Liu Wen couldn't believe it no matter what.

As the iron items on the silver-black mutant rat's body shot out, Liu Wen discovered the color of this immortal mutant rat.

And what shocked Liu Wen was obviously far more than that.

The iron object that had been shot out of the silver-black mutant rat had whaled again, and after it howled again, it flew back from a distance and smeared itself again.

The iron items on the silver-black mutant rat came and went, but Liu Wen found that at least tens of thousands of zombies died in this blow of the silver-black mutant rat.

The iron items on the silver-black mutant rat were stained with black zombie blood.

The ability shown by this immortal mutant rat has never been seen by Liu Wen.

However, Liu Wen estimated that the ability of this immortal mutant rat should not be much different from his metal solidification.

When he saw this silver-black mutant rat, Liu Wen could feel it in the dark, and its ability was the same as Liu Wen's metal solidification.

In other words, normal humans, if they take the silver special crystal nucleus, have a chance to awaken the ability of this silver-black mutant rat.

It's just that Liu Wen quickly vetoed this idea.

Previously, Pan Peng was a person who cultivated a million plant abilities, and a million people who awakened metal solidification.

Taking plant-based abilities, there are five or six kinds of plant abilities that are awakened, large and small.

The only thing that was cultivated by the bright silver special crystal nucleus that awakened the metal solidification ability was the one million people who spawned it, and the awakened abilities were all metal solidification, and there were no other awakening abilities.

At that time, seeing the report handed over by Pan Peng, Liu Wen was also surprised.

However, Liu Wen didn't take this matter to heart at that time, and when he saw this silver-black mutant rat at this time, Liu Wen suddenly remembered.

couldn't figure out the key, Liu Wen simply stopped thinking about it.

On the mutant rat's side, because of the participation of the silver-black mutant rat, the powerful zombies were defeated one after another.

In the caves that were dug out by the little blood before, mutant rats continued to emerge.

Under Liu Wen's instructions, the caves dug by Xiao Blood are all very large, even if they are mutant beasts of Wang Pin and Spirit Pin can be drilled out.

The background of the mutant rat group is even stronger than Liu Wen imagined.

A silver-black mutant rat is already very perverted, Liu Wen in the sky, his eyes are very sharp, and he soon saw that next to this silver-black mutant rat, there were two more immortal mutant rats.

The two mutant rats, one blue and one light blue, are supposed to be water and ice.

A silver-black mutant rat had already made the remaining zombies a little defeated, and at this time it had two more companions of the same level.

In comparison, the zombie side instantly became the object of slaughter.

"Hey, the overall situation is basically decided, I'd better withdraw!"

Liu Wen, who originally wanted to watch the play in the sky, saw the mutant rats break through the defense line of zombies, came to the outer city, and began to hunt humans in the outer city.

Liu Wen, who was still ruthless before, also began to be unbearable.

There are so many fresh lives, and because of Liu Wen's decision, they are going to die.

Liu Wen killed people after the end of the world, but in any case, more than ten years of education in the era of peace still made Liu Wen's heart still not reach the point of being hard-hearted.

couldn't bear to continue watching, Liu Wen finally had to choose to leave quietly.

"When these mutant rats see humans, they should kill them directly."

"So, I don't have to stay in the island country either!"

"Mom sells batches, is busy with a lot of work, and in the end it is actually in vain!"

"Forget it, go to Minako's side to have a look, if they leave, I'll go back to Huaxia too."

"If they hadn't left, I'd just leave and let the family wait, which is a bit immoral."

After the mutant rats have killed a large number of zombies, the mutant rats have begun to attack the humans.

Now that it is the end of the world, most of the people who can survive are relatively brave.

When the mutant rats began to slaughter humans, a small group still organized and began to rebel, and even hunted the mutant rats.

Mutant rats eat zombie corpses, but they don't eat zombie crystals.

Mourning crystals that are discarded on the ground are easy to pick up if they have a good tone.

Many of the islanders who were kept in captivity by zombies in the outer city of the giant fortress picked up the mourning crystals and quickly swallowed them to improve their strength.

When their strength improves, these people gradually have the strength to fight the mutant rats.

Of course, those who choose to fight are still in the minority.

In any case, ninety percent of this giant fortress is made up of women.

Compared with men, women generally lack the courage to die and live later.

Gender weakness, this is innate, and few girls can overcome it.

More people, still seeing the zombies being killed by mutant rats, began to run frantically, hoping to leave the giant fortress, the zombie human farm.

At the same time, there are also some people, during this time, who have suffered some inhuman treatment and mental breakdown.

Many of these people who had a nervous breakdown did not choose to run away, but were stunned on the spot, waiting for the slaughter of the mutant rats.
