At this time, Chen An naturally came to the town outside the city.

In fact, after finding Zhang Song, Chen An handed over the task of escorting them back to Silver Wing, and he rushed here against time.

In order to count, or maximize the harvest.

Originally, he just wanted to harvest some survivors to expand the scale of the underground base, but he didn't want to just feel sorry for the loss of manpower and chase all the way to have such a gain.

The first time I came here was to use candlelight and shadow to find out the source of the anomaly here.

Compared to the body of the Flying Yaksha, there are too many means that can be used as the closest to the ontology.

Not to mention the means of fusing the Doomsday King Teñora, just a candlelight allowed him to see through all the secrets of this treacherous town.

Following the clues he "saw", he came all the way to the gas station. The anomaly he sensed was in the underground oil depot.

It seems that there has been a certain anomaly in time and space due to the change of the world's energy level, which has caused the boundary membrane here to be broken by a small opening, causing the pollution of the gods and demons in the outside world to infiltrate directly without any obstruction, and it has a certain effect with the origin of the world and gives birth to a large amount of negative energy.

The energy level jump of the world is not absolutely safe, if it is infiltrated too much by xenomorph energy, then the whole world will face the real apocalypse, the world is completely polluted by the power of gods and demons, everything is swallowed by that terrible weirdness, turned into nothingness, and only exists in concepts.

Of course, the destruction of this world has nothing to do with Chen An, he just wants to watch the excitement, and in addition, use the rich negative energy here to try to break through the energy degree of the fifth level of reincarnation.

Although relying on his experience from a high vantage point and the peculiarity of the Doomsday Monarch's personality, the combat power he can exert is not much better than that of an ordinary reincarnation level 5 and 6th level powerhouse, but that is only frontal combat power.

He's not here to fight.

One is to collect as much information as possible about the plot of the world, and the other is to leave enough imprints to be remembered.

Neither of these can be done by simply improving combat power, and many things still have to rely on the realm.

It's like the immeasurable phase transformation, which can't be used at all without a certain realm.

Although four taels can dial a thousand catties, but first of all, you have to have the strength of four taels, if you don't even have the strength of four taels, what to talk about to overcome the rigid with softness, and defeat the strong with the weak.

For many people, the fourth level of reincarnation to the fifth level of reincarnation is a leap in the great realm, and it is a qualitative change, and it is almost the same for Chen An.

At this level, most of the power belonging to the Doomsday King will be able to exert himself, and as the embodiment of the Sense of Thought, he can also have a greater degree of recovery, and he can barely use the means of fooling the gods and ghosts.

With these, he can almost be said to be rampant in the current world, and he is truly rampant.

If the heavens are the dojo of creation, then the ten thousand worlds are the courtyard of the immortal monarch.

The level of the world is the level of the sky, which is the level of the light of the sky.

Even like the fragmented world in front of you, there may only be a Biluo level, that is to say, the sixth level of reincarnation is the limit, and if you enter the seventh level of reincarnation, you will be completely broken if you are not careful, and even the world will be wiped out.

As a limit, it is naturally not so easy to reach, it is a level that can threaten the world, and there must be many levels, and even many people need to go forward and explore one after another.

Therefore, the fifth level of reincarnation is the current upper limit of this world, and even in Chen An's prediction, if there is no accident, it is absolutely impossible for anyone to reach the fifth level of reincarnation in just one year.

Therefore, it is definitely not a lie to say that the fifth level of reincarnation can run rampant.

So, Chen An directly put down everything and went deep into the underground oil depot without hesitation, ready to start pouching this biggest harvest for An.

Even ordinary people know that no matter what happens in the future, it will not be wrong to improve yourself first and make yourself more valuable and powerful.

Because of the limited perception of the flying Yaksha, the last time I came, I really didn't notice anything here.

However, the incarnation of Sigan has perceived people, and at first glance, he found that this underground oil depot was between existence and non-existence, almost unreal.

If ordinary people stay here for a long time, it is easy for them to become conceptual because of the conflict between the two worlds.

Even with Chen An's fourth-level reincarnation strength, it is a little difficult to walk here.

Fortunately, there are many semi-conceptual ghosts wandering here, Chen An grabbed some casually, and used them to make a small lotus platform to isolate the real and the unreal, and protect Cheng Yu's body from infringement, so he began to cultivate with peace of mind.

This cultivation is more than a month past, because there is no realm bottleneck, so the fifth level of reincarnation is a natural leap.

Chen An stayed here for another three more days, completely stabilizing the realm of the fifth level of reincarnation, and only then walked out of here.

The town outside has been transformed by the walking corpses for more than a month, and has become a new look.

The ghosts trembled under the obscenity of the zombie uncle, and helped to clean up as much as they could.

Chen An wandered here, and there was a feeling of returning to before the end of the world.

Of course, first of all, we have to ignore the blank guys all over the streets.

A small three-story building next to the gas station was converted into his laboratory. The carcasses of the three-tailed tiger and six porcupines, one large, five and six porcupines, were also placed on the experimental table on the first floor.

Although it has been preserved by a special method, it has taken more than a month to lose a lot of energy contained in it.

Therefore, Chen An temporarily put aside the research on zombie refining and began to explore the production of soul cards.

There is a mature method of making soul cards in the Eastern Wilderness, and Chen An naturally tried it first without hesitation, but the result was naturally a failure.

Without him, it's just that the bloodlines of these monsters are too weak.

The products of these genetic mutations are not qualified to make even ninth-level soul cards at all.

Chen An is not discouraged by this, because it is predictable.

He then used the inscription technique he had invented to extract pure blood.

The result is still a failure, these guys obviously do not have a prominent ancestor, a prominent bloodline.

For five days in a row, Chen An tried various methods, but the results were not very good, and in the end, he was not allowed to integrate the world's method of making mutant potions into it.

Use the core of the beast to carry the flesh and soul soul, engrave runes, and make soul cards.

This method is not surprisingly successful, and the energy contained in the beast core fully provides the mechanism for the existence of the soul card.

It's just that Chen An's idea of mass-producing mutant warriors fell through. This is still a beast core to create an ability, but compared to the mutation potion, the success rate of this soul card is 100%, and the others do not provide excess value.

This may be limited by the laws of the world and cannot be forced.

So although Chen An was not too satisfied with this result, he still had to put it aside for the time being.

In fact, this achievement is not easy for many people.

Chen An's Beast Core Soul Card can definitely create an ability, but the mutation potion only has a certain chance to be created.

According to Xu Zimo, even in the last ten years, it has not been able to solve the problem of the success rate of the mutation potion, and the number of supernatural people is still scarce.

No longer entangled in this problem, Chen An began to focus on the research of zombie refining.

With the support of abundant negative energy, and the model of ghosts as a reference, the research process is quite smooth.

In less than a week, Chen An worked out a complete set of strategies.

First, he captured the zombies and took them to the underground oil depot to remove the corpse core.

This step is a must, otherwise the zombies that cull the core will quickly collapse.

Then, the negative energy is channeled to infect the remaining body and reshape its structure.

Finally, it is refined by refining the walking corpse.

A more flexible corpse has emerged than a walking corpse made from a pure corpse.

Compared to the walking corpse in its normal state, it is more flexible and "intelligent", but it has a tyrannical emotional residue and is more bloodthirsty.

If there is no suppression by the existence of high-level personalities, they will not even let go of their kind, and they must tear each other apart before they are willing to give up.

But fortunately, it retains some of its sanity and can be used, and its actual combat power has basically reached the level of a second-level zombie.

Chen An didn't hold on to that little flaw anymore.

After doing this, he originally planned to continue to study the magic circle that uses negative energy to increase the strength of zombies, and try to improve the cultivation of corpse refining such as Silver Wing.

But after careful calculation, he had been away from the underground base for two months.

Although he generally understood some of the situation there through the telegram in the middle, it was not as good as him personally presiding over the overall situation and reassuring his subordinates.

So he had to put aside the work in his hand for the time being and go back to the base.

As the apocalypse progressed, the post-apocalyptic wilderness became more and more dangerous, and for two months, even level 5 zombies began to roam the streets frequently.

It was an existence capable of fighting second-order abilities.

But these are not a threat to Chen An at all, and the wilderness and streets are still smooth roads for him.

So it didn't take much effort for him to go back to the base.

The base had changed a lot from when he left.

In the distance, you can see a behemoth with a three-foot high wall.

In addition to the original underground part, the above-ground part also includes several nearby blocks, which really has the appearance of a small city.

From time to time, people enter and exit the huge city gate, which is a hunting team belonging to the base, transporting supplies.

Through the contact in the telegram, Chen An knew that the destruction of the municipal base had brought them almost 50,000 people, and in the following two months, this number quickly climbed to nearly 100,000.

Coupled with the members of the hunting team who rely on the base to survive but do not live here, this number will rise by one point, approaching the 200,000 mark.

This number not only shows that the Chen An base is thriving, but also indicates that a hidden danger is coming.

That is, the iron law that a base of more than 100,000 people will inevitably attract the invasion of zombie tides.

In the timeline of Xu Zimo's previous life, the large base has to fight against the zombie tide every once in a while, and if it bears it, it will continue to develop, and if it can't bear it, it will be wiped out.

Although I don't know where so many zombies came from, this iron law has never been broken.

The main thing for Chen An to come back this time is to solve this problem, and if it is not good, he will first carry a wave of zombies to attack the city.

Of course, there is one more thing besides that.

That is, his base is expanding too fast, and the large influx of people has made the base uneven.

Although the surviving high-level of the municipal base has built a new survivor base in another place, some people have fled to Chen An's base, thinking that this place is good and does not want to leave.

If you don't want to leave, you don't even want to point fingers to gain power.

Although Xu Zimo tried his best to maneuver, his strength was still too shallow, and the other party's emaciated camel was bigger than a horse, which once caused Xu Zimo a lot of trouble.

So Chen An came back this time to solve the problem of the zombie tide, and he came to give Xu Zimo a platform.
