The old man you see with your phone is highly suspicious.

As soon as she finished speaking, a large black dot appeared in the sky above the city as if tearing through space. It looked like a ferocious black dragon from hell, covered with twisted spikes, and human skulls were like beads on a necklace hanging around the neck.

It looked extremely terrifying and distorted, and as soon as it appeared, the endless humanoid balloon demons in the eyes of the Divine Purification Demon Eye also started to move. They rushed towards the dragon as if they had spotted prey or were going crazy.

One by one, the balloons exploded the moment they touched the dragon, and the blood and bones turned into fragments that made the dragon demon stagger. Some of them desperately pounced on the dragon's back and began to tear at the dragon's wings with their hands and feet.

In the Ghost Eye, the people on the hot air balloons were shouting and trying to stop the dragon. People dressed in flying squirrel suits jumped off the hot air balloons. Xue Dinglu saw that those people in flying squirrel suits were carrying huge bombs on their backs.

Upon contact with the dragon, they decisively detonated the explosives on their bodies, turning into aerial bombs in an attempt to kill the dragon demon.

"You damned bastards! I need to save people! Are there any humans left? Even just one person would be enough! Humans! Is this metropolis, which once housed tens of millions of people, truly devoid of any survivors? Whoever you are, as long as you're alive, I'll keep you alive. I'll risk my life to protect you and bring you back to hell. Please, whoever you are, if you're still alive, come out now..."

The dragon demon's roar seemed to echo throughout the entire city. It appeared to have used a special magical technique, making it audible even to Xue Lude and his family, who were nearly a hundred kilometers away.

However, by the time the sound was heard, a long time had passed. The dragon demon flew around the city but found no living people. Finally, it could not withstand the attacks of the evil spirits and left the city's skies, covered in blood and wounds.

The humanoid balloons throughout the city stopped attacking the instant the demon left, and continued to drift slowly in the sky as if nothing had happened.

After witnessing this scene, Xue Luding and the little witch fell silent. This upside-down scene made them feel as if their worldview had been completely shattered.

"Just now, that demon seemed to be saying, 'Save humanity'?" The little witch hesitated, then realized that more than half a year had passed since the end of the world, and judging from the dragon demon's appearance, it had been doing this for half a year.

Really are……

The demon wants to save the survivors and vows to protect them to hell at the cost of its own life. Judging from its almost tearful appearance, it would probably be overjoyed to see a survivor.

Why would I have such a dream? And am I even conscious?

The little witch even wondered if she had been under a demon's spell, otherwise how could she have encountered such an absurd situation?

She was looking at the distant city through a monocular telescope, unsure of what to do next.

Xue Dinglu, who had been constantly switching between three perspectives to observe the scene, suddenly had a guess.

Could it be that the evil spirits were created by the world itself as a weapon to deal with outsiders like demons?

An immortal, incorporeal, ferocious monster is used as a weapon in external warfare. It can even turn any dead human into a demon. As soon as these biological weapons appear, they will immediately become the most terrifying monsters.

Just like now, in the vision of the Divine Purification Demon Eye, balloons appear out of thin air in many places in the sky, growing bigger and bigger, gradually becoming human-shaped balloons that continue to float in the sky.

Since demons are immortal, then I will also be immortal, until the demons dare not set foot in this world again.

As for demons needing human fear to grow stronger, then I will kill all the humans in the world, leaving only evil spirits, and thus completely banish the demons.

What happens after humanity dies out? Actually, they don't really die out. Didn't they become evil spirits? They're just a species living in the world as souls. Although it's a bit strange, the world wasn't destroyed by an invasion of outsiders, was it?

In fact, it is possible to preserve only 1-2 human samples. Once all the alien demons have been driven out, the genes of those 1-2 people can be replicated and cloned, and human civilization will return.

The world will recover, and the external enemies will be completely eliminated. This situation is merely a restart of human civilization, and it is not an unacceptable thing for the world.

When this ruthless thought came to mind, Xue was immediately stunned by it.

This idea only arose under absolute rationality, using a tactic that would inflict heavy losses on both sides to completely expel the external enemy. It was also a plan that could only have been developed under the assumption that the demons were alien invaders.

That's simply... an absurd and laughable line of thinking...

However, based on the existing information, given the super-fast operation of Xue's Law's CPU and its astonishing wisdom, there is at least a 40% chance that this is the case!

In other words, this world may not have been destroyed by others, but by its own hands!

When Xue Dinglu realized this, he was stunned again.

He then looked at the little witch, unsure how to voice his conjecture.

It's even possible that the little witch was the last spark sent by the world...

Although she is a living dead, she is no different from a normal person and is fully capable of bearing the hope of human revival. Furthermore, because she is essentially just a living dead connected to the giant walnut tree, an alternative "corpse-dissolving immortal", her lifespan is extremely long.

She grew to the point that as long as the giant walnut tree stands, she will never perish...

So, whether it's the Divine Purification Demon Eye, her own abilities, or the 200 million and 800 million that appear when you look at her with the Divine Purification Demon Eye, is it all just because she is essentially an extension of the giant walnut tree Margaret?

Despite its absurdity and contradictions, Xue's Law, after running through it with its astonishing wisdom, made a horrifying discovery.

There is a greater than 30% chance of this happening!

He was startled by his own thoughts, and the little witch beside him immediately noticed that Xue Dinglu had suddenly shown a hint of emotion.

This emotion is even named—fear!

Although very faint, it was noticeable enough to make her both happy and worried.

"Brother, what's wrong with you? Did you find something?" she asked Xue Dinglu.

Xue Dinglu did not reveal his conjecture, as it was merely a guess, and the idea was too shocking to disclose without clear information.

"It's nothing, I was just wondering if the demons might be the work of Margaret the Great Walnut Tree," Xue simply said.

"Sigh...sigh?" The little witch was stunned for a moment. She should have immediately scolded and reprimanded Xue Lude, since their religious deity was Margaret. However, when she thought of how Margaret had tried to vomit out the evil spirits she had led away, she trembled.

Was the world destroyed by Margaret?

This blasphemous thought sent a chill down her spine in an instant, but the more she tried to stop thinking about it, the more of these terrifying thoughts surfaced.

“Let’s go and look for any information left behind by our ancestors in the city, especially information about Doomsday,” Xue Dinglu said.

They had originally planned to find survivors, but after the dragon demon's performance, even the little witch and the others had given up hope of finding any survivors.

A cross-shaped portal appeared at the front of the city.

As soon as Xue and his companion appeared, the humanoid balloon in the sky swooped down. However, halfway down, it seemed to see something extremely terrifying, and immediately rose back into the sky. Then, it saw the two again and continued its descent...

Like a program stuck in an infinite loop, it keeps repeating the same action.

In Ghost Eye's vision, their flying machine was constantly malfunctioning and out of control, roaring downwards incessantly, reminding Xue Lude to hide and get away from the monsters around him.

This chaotic world.

Xue's Law still hasn't figured out who his enemy is. Is it a demon? A devil? Or perhaps Margaret the giant walnut tree who reacted immediately?

He seems to have really lost his sense of the world.

Even now, he was hesitant to make a move, firstly because the World Innovation Era couldn't be activated, and secondly because he was afraid that a single slap would kill all his allies.

But it seems that neither demons nor monsters are immortal... Oh well... whatever...

In short, it's a fucking abstract, messy, ditch world.

Why not just beat the whole world up by yourself? You're tired, just destroy it already.

Xue Lude glanced at the little witch beside him; she seemed to still be in shock that all the evil spirits were created and released by Margaret.

The little girl is just naive. A child who drops out of school at the age of 6 would probably be the kind of working girl who would be easily tricked by a blond-haired ghost on Earth.

Xue's intuition was correct; although the child appeared very wary, she was essentially a larger version of a little dragon girl.

There is a kind of pure beauty that has not been tainted by knowledge.

Xue Dinglu hasn't yet made any speculations about her being an incarnation or clone of Margaret, otherwise this guy would probably be feeling depressed again.

The thought that Xiaolongniang might grow up to be just as innocent as this girl made Xue Dinglu feel very sad.

Xue felt he should thank this little witch for her ability to control his own feelings of sadness at any time.

Otherwise, he probably wouldn't feel sadness for a long time.

"Do you still want to continue purifying this city? I warn you, purifying this city might invite another attack from Margaret the Great Walnut Tree," Xue Dinglu said.

Or, more likely, Margaret will come back to stop her purification, and even vomit out the evil spirits that have been led away.

Even Xue's Law doesn't know if extraditing evil spirits is the right thing to do. Perhaps their actions are still disrupting the world's pre-existing arrangements.

Who knows, maybe evil spirits really are the ultimate weapon against demons?

"So, what are your plans, brother?" she replied.

“I’ll stay here for a day. I want to meet the dragon demon and try to go to Hell, the lair of demons,” Xue Dinglu said.

In this world, the Pure Land and Hell are clearly not part of the same system. The Pure Land theory is that it is a resting place for souls controlled by the giant walnut tree Margaret. Hell is obviously a subspace, and according to the existing information, it is inhabited by a large number of demons and a small number of humans.

Judging from the dragon demon's anxious appearance, there were probably very few humans inside, which is why it was crying so desperately, even resorting to desperate measures to find a few survivors in this already destroyed world.

After all, according to the previous setting, demons can only become stronger by relying on human fear.

In a normal world, this kind of thing that abducts humans and survives only by fear would have been wiped out by Xue's Law long ago, and before being wiped out, it would have been said with the words, "If you are a demon once, you will be a demon forever."

But in this grove of a world, even the demons who don't want humanity to be wiped out seem to have such handsome features.

Upon hearing that Xue Dinglu wanted to go to hell, she was instantly stunned, and then felt extremely uneasy.

“Your compatriots might still be in hell; they were just kidnapped, and they probably didn’t die,” Xue Dinglu said.

"Then let's wait for the Dragon Demon here! A demon born evil, I will personally rescue my brethren!" She instantly demonstrated to Xue Luding what it meant to change one's expression without needing chakra, making Xue Luding roll his eyes.

Chapter 351 The Great Detective Sildenas

Compared to the countless human-shaped balloons in the sky, there were almost no evil spirits on the ground in this city. The whole city was very quiet, and there were no strange traces around.

This seems to further confirm Xue's theory.

This city is the hunting ground of the dragon demons, so all the evil spirits here are humanoid balloons or other flying evil spirits. They hover in the sky all the time, waiting for the dragon demons to arrive.

Whenever the dragon demon appears, these humanoid balloons will rush forward desperately to fight it.

In the city where the little witch first lived, not all demons were flying; on the contrary, flying demons were relatively rare.

Perhaps it's because the demon in that city is a snake demon, or perhaps it's simply that demons haven't appeared for so long that the evil spirits there haven't evolved to deal with them.

Therefore, Xue Dinglu was even more determined to go to hell to see if it was really as he guessed, that there were no living people left in the world and that the only living people were in hell.

The end of this world is caused by the world's own stress response, which creates evil spirits to fight against demons. In the end, the world decides to simply destroy the demons, so it turns all the people in the world into evil spirits, leading to the arrival of Doomsday.

Looking up at the sky, Ghost Eyes reported that numerous hot air balloons and pilots in flying squirrel suits had arrived not far above Xue Dinglu's head.

A voice kept coming from above: "Captain, my devices have malfunctioned. Damn it, they all stop working as soon as we get within a kilometer of that monster! Our consciousness will also be affected by that monster."

“There was a human with that monster. We can’t let our fellow human being be deceived by the monster. We came a kilometer away and used a loudspeaker to warn him. No matter what, we did our best.”

"Hey! You over there, get away from the monsters and hide in the shelter. There's food and water there. Or you could hide in the city hall; there are some supplies there."

"Run! Run! Don't be fooled by the monsters around you!"

In the sky, the loudspeaker on the hot air balloon kept speaking to Xue Lude and the little witch below.

In Ghost Eyes' view, this was not a long-abandoned ruin, but a city specifically built to support hot air balloon and flying squirrel suit pilots.

The streets below were lined with shops supplying hot air balloons, but the city was sparsely populated.
