Before arriving at the [Top Wall], it would be impossible to say that Ning Fan was not nervous at all.

In the past, the Santong Cooperation Zone sacrificed countless generations of lives in order to protect this place.

Although Ning Fan now has enough power in his hands, he never thought that after coming here, he could easily stop the strange beast outside the [Top Wall].

Even though it seems that Ning Fan has enough power and it is difficult for the strange beasts to pose any threat to them, in fact, the real hidden danger is not on the surface.

It’s a very simple truth that humans can only defend but not attack.

If Ning Fan really didn't care about casualties, he could definitely deal with these strange beasts.

Even with those fourth gear dark tide dragons...

Ning Fan also has a strong man of the [Thousand Soul Level]!

But even if all these strange beasts in front of us are eliminated, what then?

Can they go deeper?

Of course it is impossible.

In the depths of darkness, there are five levels of strange beasts.

As long as no [Ten Thousand Souls Level] strongman appears on the human side, there will be no chance for humans to step into that darkness.

In other words, even if all the monsters they are facing are killed, humans will still have to stay here, with the [Top Wall] as the boundary, waiting for the monsters to regroup.

The reproduction speed of the exotic beasts may not be very fast, but they do not have to worry about being conquered.

And what about humans?

Humans grow old.

As you get older, your strength declines.

Both Jia Hu in the past and Wigginton now have demonstrated this point very well.

When the strength of the strong men on the human side decreases, will they still be able to withstand the attacks of the alien beasts so easily?

Of course, new strong people will emerge in the human race.

But the speed of appearance can definitely not make up for the frequency of decline.

Don't forget, the reason why Ning Fan was able to assemble such a strong team now was because he had gathered all the resources of the entire Lower City.

Including the inventory left over from decades in various regions.

When this group of people no longer have the current style, it will be difficult for newcomers to keep up.

Then there is human nature.

For now, the downtown area is united.

On the one hand, Ning Fan is here.

On the other hand, everyone has a common expectation in their hearts, which is to completely eliminate the alien beasts.

They also want to see what the scenery in the upper city is like.

It is under this common goal that humanity can maintain its existing unity.

But as more and more people discovered that even after they united as one and gathered all the strength they could muster, they still couldn't break through the door guarded by the strange beast...

The idea may change.

Things that come together for a long time will eventually separate, and things that separate for a long time will eventually come together.

This is normal and inevitable.

So no matter from which angle, the pressure in this fight against the alien beasts is on the human side.

To be exact, it was here with Ning Fan.

On the way here, Ning Fan's first thought was not how to destroy the strange beasts that might appear, but to learn more about them.

Analyze the behavior of high-level exotic beasts through low-level exotic beasts.

Ning Fan has indeed obtained some information at present.

However, some information still needs to be verified.

Ning Fan instructed Duan Weijun to be responsible for all subsequent attacks, in fact, it was to verify some things.

The appearance of the giant swamp rhino gave Ning Fan inspiration.

Ning Fan now wants to see what kind of response the alien beasts will make when humans no longer use strong men, but fight against the alien beasts in a pawn-to-pawn manner?

Most importantly, the artillery fire will destroy every wave of alien beasts that rush into the range, which will prevent the corpse monsters from evolving.

If the corpse monster still doesn't kill people in their own camp, it means...

[Top wall], there are special restrictions.

Monsters are not allowed to kill each other.

As long as this information is confirmed, Ning Fan can then discuss the next research direction with Wen Xiuyuan.

Perhaps this will allow mankind to find a new direction.

After explaining his ideas, everyone understood what Ning Fan meant.

Since the pressure from the alien beasts is not great now, their next core direction is to send information!

Ning Fan even contacted Wigginton directly and asked him to send someone to escort a team from Yecheng here.

In the past five years, Yecheng has established a new department.

Exotic Animal Research Institute.

The dean is naturally Wen Xiuyuan, who is also the dean of the institute.

This department does not participate in the institute's projects, but specializes in one.

The behavior patterns of strange beasts.

The information left by Ye Liang had long been thoroughly studied by the people in this department.

In addition, the front line would deliver the corpses of some exotic beasts to them, giving them plenty of opportunities for research and analysis.

They even set up temporary research points on the previous front lines.

The purpose is that if the conditions are right, some living exotic beasts will be sent from the front line for them to explore.

This time, Ning Fan did not dare to bring these talents with him because he was worried about encountering any special situations on the way, and he was not sure about the situation on the [Top Wall] side.

Now, in Ning Fan's opinion, it's almost time.

On the second day after the team set out, Ning Fan received news from there.

On the way, they encountered strange beasts.

A large number of powerful monsters.

Ning Fan immediately understood that these should be the group of strange beasts that attacked Gerlan's team.

After Gerlan was ambushed, Ning Fan thought that these strange beasts must have felt that Gerlan's team was too powerful and they could not cause much damage to it, so they chose to temporarily avoid the attack.

At the same time, they will not give up easily.

Ning Fan always felt that they might have stayed in the area on purpose.

Its purpose is to stir up trouble behind the backs of human beings and not give them any peace.

That is to say, they will not engage in head-on confrontation, but will choose more suitable prey.

Obviously, the people from the Exotic Beast Research Institute are very suitable.

Almost none of these people have spirit servants. They are all pure "intellectuals" and have no resistance of their own.

At the same time, in order to speed up the journey, there was no army accompanying them on this trip. Only a group of guards were sent out symbolically to escort them, with a total number of about 300 people.

This configuration is simply too weak compared to the sneak attack on Gerlan they had previously launched.

Therefore, this time, after a brief exploration, the alien beasts gathered most of their forces hidden in the dark and launched a fierce attack on the team of the Alien Beast Research Institute.

Judging from the information Ning Fan received, the number of strange beasts this time was at least over ten thousand!

However, Ning Fan, who received the news, did not feel nervous or panic at all.

Because there is someone who is also in this team.

Wigginton, the Destroyer.
