For the next few days, Qiao Du sometimes controlled her clone to wander around the city, and sometimes looked at the search results of the drone here.

It's a pity that the drone didn't find anything special except for a few litters of beasts, not even the shadow of the demon.

"Speaking of which, I don't know how much research there is on demons in the DPRK?"

Kiriyama rode a horse and walked beside Xu Fu's carriage.

In the past few days, he has used his strong social skills to develop a relationship with Xu Fu, and he has gained the trust of the other party, and he can walk next to him, which makes the assistant Hui Jiang in the blue robe quite jealous.

"Demons and evil have been around for a long time, and there are historical records for thousands of years, as for the earliest source, there are three theories."

Xu Fu touched his beard and then spoke.

"One of them is that these demons came from the demon world outside the territory, and accidentally invaded here, and over the years, they have continued to grow and fight with humans, and the founding emperor also united everyone in this battle, so that there is a foundation for eternity."

"Another theory is that the soldiers who rebelled against the first emperor were not tolerated by heaven, were cursed, turned into worms, and continued to multiply and attack mankind because of their resentment against the first emperor."

"There is also a theory that these demons were soldiers cultivated by the faint monarch of the previous dynasty, and they expanded their territory, and after the previous dynasty was destroyed by the tyrant's mediocrity, they turned into ownerless monsters and caused chaos on this land."

After listening to the three theories, Kiriyama felt that the first one looked the most outrageous and was the most likely.

After all, according to the reproductive ability of these bugs, if they are really indigenous creatures, there is a chance that there will be no human beings.

Human beings are still too backward and primitive in foreign lands.

Therefore, the emergence of this creature must have been after the formation of human civilization.

This point, in fact, Qiao Duan has also mentioned it before.

There are many worlds with similar parameters in Qiao Dui's [My Civilization Simulator].

If a world with such a ferocious group of monsters appeared earlier than human civilization, then human civilization would either die young, or it would take on a completely different form of civilization in its cognition, such as merging with monsters, or using these monsters to develop in a big way.

And Penglai, from the perspective of civilization development, is more like a normal civilized feudal dynasty period, which means that before the formation of the current form of civilization, those demons did not exist.

So, in connection with that, they are more likely to be visitors from outside the world.

As for the other theory, it is more like someone performed a ritual to summon evil gods, and finally summoned these things, and in any case, these insects should have come from a foreign land.

It doesn't matter how they came to be, Kiriyama mainly wants to know if the humans in this world have any ways to restrain the demons.

"It's very difficult for us to catch living demons, because they seem to have no reason, as long as they are alive, they will continue to attack other people, and they will also use humans as a breeding ground to breed, and once they get close, they will be infected, so for so many years, almost no living demons have been caught by us."

Xu Fu didn't hide it.

"It's just that in the time of the founding emperor, it seems that someone once caught these demons, and they came to the conclusion that these demons are not unkillable, as long as they are burned with flames and their heads are cut off with swords, they can be solved, just like wild beasts."

"So, it's just that these demons have a very strong ability to reproduce, so they have lasted for so many years."

Kiriyama bowed slightly.

In fact, there is something strange about this, if these insects are really very strong in their reproductive ability, then human civilization should have been wiped out long ago, and there will be no creatures left outside the gate, it is estimated that it will only be a desert.

Such a strong reproductive ability is enough to crush the ecology of this planet.

"When Your Majesty gets the elixir, we will master the way to repel these demons, and when the time comes, the people of Li will not have to endure the infestation of these monsters."

Xu Fu is still very optimistic.

"Why do you think that if you get the elixir, you can eradicate these insects forever, logically speaking, isn't the elixir just immortal?"

Kiriyama suddenly felt as if he was talking in the tone of Qiao Dui.

"Since you can not grow old and immortal, then presumably other immortal methods are not a problem, although I don't know, but according to Your Majesty's intentions, Penglai Immortal Island is the cave of the Heming Daoist, which contains many treasures, just one is enough to settle the world."

Xu Fu said again.

It's reasonable to think about it, there must be some magic weapons in the Immortal Cave Mansion, all of which can be immortal, what kind of sword flying, asking for rain to drive away ghosts, it must be sprinkled with water.

In fact, judging from the history of the future, this elixir does carry enough pollution to mutate people, and Xu Fu's judgment is not wrong.

"The front is the city, although I haven't been here, but I have read in the book, this place has been a border pass since fifty years ago, so many years, it has been repeatedly invaded by demons, but it is still standing, it is a veritable lonely city."

Xu Fu said to Kiriyama like a tour guide.

"Indeed."

Judging from Qiao Dui's video, Wushan is indeed a prosperous city, in this border of civilization, it is enough to enjoy the fun like a god's capital, if it is not for the invasion of demons from time to time, this can be said to be a paradise, and the officials sent here can be regarded as the local emperor.

"We're almost there."

Seeing the sign standing on the side of the road, Xu Fu knew that he was about to arrive in Xucheng.

The pattern of the city is different from other places.

According to the opinion of those Qiao Du's clones who go inward, the cities in the interior do not have towering walls, but are more like open cities, and the scale of the cities is larger.

And close to the border, it becomes a city with high walls.

Generally speaking, if the outer city falls, then the inner city will start to build walls, and it is inevitable to shrink the city, on the one hand, the small size of the city is easier to defend, on the other hand, the people do not dare to live too far away, everyone will involuntarily close to the center.

The farmland that he had only seen on the screen of his phone before appeared in Kiriyama's sight, and he looked at the people who were busy in the farmland, and even found the couple that Qiao Du had greeted before.

"Hello!"

Qiao Dui, who was sitting in the carriage behind, immediately waved his hand and greeted them.

The couple frowned, wondering why Qiao Du suddenly appeared here again.

These farmers should have never read a book and couldn't read big characters, but they could also see that Xu Fu's team had an extraordinary background, especially the person in blue clothes, who looked like a big official.

Because they had never seen a high-ranking official in a red robe, they mistakenly thought that Huijiang was the biggest official here.

Seeing this, the peasants on both sides fell down and bowed.

As the team continued to move forward, they saw that the gates that had been closed had been opened, and outside the gates, a group of heavily armed soldiers were lining up.
