I sell goods in the last days

East of the city, after crossing the planned road, it is almost all factory buildings and some old houses that are about to be demolished.

Further east, there are some new development areas, where there are many new real estate, and the occupancy rate has also increased a lot in recent years.

Xu Feng drove in the old factory, which had become even dirtier because it had long lost its traces of humans.

There was a strong smell of blood in the air, which made Xu Feng frown a little. There is no human activity here, where does the smell of blood come from? However, it didn't take long for him to discover the source.

In front of a food processing factory, there are a lot of blood stains, and there are various animal carcasses. Xu Feng took Li Xin to the gate, looking at the broken animal carcasses on the ground, barely able to distinguish their categories.

These animals include mice, insects, and some cats. There are many types, but they all have one thing in common, that is, it seems to have been bitten by something.

"Can you feel what's inside?"

Xu Feng asked Li Xin beside him, and the latter shook his head gently after carefully sensing it. Seeing Li Xin's actions, he had ruled out the possibility that there would be zombies inside.

"There are some residual mutant beasts inside, the grade is not high, and the number is not much."

"This is strange, look at the corpses on the ground, there is no lack of fifth-order, if the grade is not high, what is going on with these fifth-order?"

Could it be that there was a big war here, and the winner is gone? So what is the winner? With this question, Xu Feng continued to walk inside.

Before long, he found a living animal, which was some mutant rats, but there were not many of them, about a hundred or so. And the level is really not high, just a few fourth-order, and the others are third-order.

Without Xu Feng speaking, Li Xin glanced at him, and then rushed up to slaughter those mutant rats. Xu Feng stood aside and thought, there were indeed many mutant rat corpses everywhere, but they were far from what they had encountered before.

Is it possible that the mutant rat population is carrying out the siege? However, this is also impossible, because according to the habits of mutant rats, if they win, they should not leave so many animal carcasses in their path.

And the dead state of those animals has bite marks and traces of being crushed by gravity. Judging from the types of corpses on the ground, no ethnic group has this ability.

That is, none of the victors of this district died, or there were sacrifices, but they were all taken away by their companions. Either way, it's not good news.

If none of them are dead, then this group of victors is strong. You can use both the Rip and Bite skill and the Large Gravity Crush skill.

If it is another, they take away the corpses of their sacrificed companions, then the wisdom and unity of this group are not ordinarily high.

Xu Feng shook his head, no longer thinking about these animals, he looked around to see if he could find any traces. Inside the factory building, as outside, there are mutated animals and mutated insect carcasses everywhere.

What made Xu Feng feel strange was that there was not much food in this factory, so why did they fight here? Is it for the sake of an appointment?

Suddenly, he found that in the middle of the factory building, there was a large vacant space, and there were no corpses here, as if there was something here before.

Xu Feng walked over, checked in this open space, and found that there was a pit about one meter large on the ground. The depth of this pit was only more than ten centimeters, and it also exuded a feeling that Xu Feng was familiar with.

"Such a familiar breath, it seems that where has it been encountered, where did it come from?"

Xu Feng thought hard, but he couldn't remember it for a while. He squatted down and reached out to feel the pit, and could clearly feel a pure ability drilling into his body.

Pure ability? The ability to absorb, similar to crystal nuclei....

"That's right, zoo."

Xu Feng suddenly remembered that when he hunted the Peacock King in Beicheng Zoo before, he found this aura in its old nest.

"Could it be that there was something here before, and all the races involved in the fight were for that thing?"

The more he thought about it, the more likely it became, moreover, Xu Feng seemed to have grasped something. He found a seat and began to connect everything and analyze it.

"When the end comes, there are only zombies and humans in the city, and all animals, even small things such as cockroaches that you usually see, are missing, which is a strange point.

And the mutant beasts in the wild, which obviously have such a powerful strength and a terrifying number of races, do not attack the humans in the city? Then there must be a reason why they don't, for example, something in the wild is more important than in the city.

The little white dog said that after the end of the world, it was guided by a mysterious attraction or instinctive need to rush towards the wild. When it has wisdom, it already has a high level of strength.

Everything is too coincidental, all hypothetical a situation, there is an item that can bring mutant beasts to evolution. Or this thing can bring evolution to all living things, and generally only exists in the wild or remote places, so all kinds of mutant beasts will stay in the wild. The

more Xu Feng thought about it, the more likely it was that when he was in the zoo before, he had speculated about this. It's just that there was a lack of data at that time, and there was also a lack of evidence, so he did not continue to pursue.

But now that this kind of thing appeared in front of him again, he thought about everything together again, and finally came to a conclusion.

"Baby, Nima, why didn't I remember it sooner?"

He is now stuck in the late seventh order and can't move, even if he absorbs more abilities, he can't realm, does that mean that he is missing something? Let's say something that makes people break some kind of confinement in their bodies?

There are also many young ladies in the base who are stuck in the sixth order, or the early and middle stages of the seventh order, before he thought about why this is, now think about it, maybe it is related to this energy.

Thinking of this, Xu Feng came to the side of the pit again, stretched out his hand and began to absorb the residual energy inside. He was doing the final experiment, and if it really had an improvement effect on himself, then some plans would have to be changed.

"Huh? The bottleneck has the feeling of loosening, but it's a pity..." After

absorbing all the remaining energy in the pit, Xu Feng did not advance, but this also confirmed his conjecture.

The thing that breaks the stagnation of the cultivation of the supernatural is this energy source.

And this energy source almost always appears in the wild. All in all, finally got a perfect explanation.

It's just that after getting this explanation, Xu Feng's face became a little solemn. After all, the danger in the wild is not something that ordinary people can resist.

However, this has nothing to do with Xu Feng, and if others can't do it, it doesn't mean that he can't do it.

Maybe this energy source will also be one of his commodities in the future?
