Rafal is huge, after all, it is a city covering an area of more than 6,000 square kilometers, and it is also the largest fortress of mankind on this continent, and according to the information he bought and the books he consulted, Yi Hai quickly got the information he wanted.

"It's only been 20 years, but a lot of things are almost gone." Holding the history book that should be very important, Yi Hai and Simir, who was sitting at the table and eating snacks, said: "But at present, it seems that the history of this world and our world is almost the same, but there is a deviation at this point in time, that's all. ”

Yihai's world and timeline are in the world two hundred years later, and it is a timeline that has not experienced a catastrophe and has successfully moved forward, and this world has suffered a catastrophe two hundred years ago, and humanity has gathered and hid in the fortress to survive, not so much as a human being, but a rat in the gutter.

"You built a wall to enclose yourself, don't you think you've seen this plot somewhere? Dr. Yihai. ”

Simir was not interested in history or anything like that, and the reason why he followed Yi Hai to this side was entirely because he had already bought all the food and supplies he needed, and seeing that there was still a lot of time left, he simply followed Yi Hai around this city that never sleeps, first to collect intelligence, and then to survey the terrain of this area, and then to drive here to escape if something happened, and to complete all kinds of information.

It's not interesting, Ihai is the most knowledgeable and intelligent leader of their team of four, after all, he is a doctor of occultism, the kind who can talk to you about anything, and just relying on a left diary to deduce so much information, although much of it has not been confirmed, but Simir is still willing to believe Yihai.

"It's not the giant who enters the O that will be staged at this meeting. Ah, found it. ”

Yi Hai suddenly stretched out his hand to cover his head, as if he had been hit by something, he felt dizzy for a while, and there was a desire to vomit, although this desire was not strong, but judging from the previous knowledge, his current situation seemed to be eroded by something, and this feeling also told Yi Hai that he should have found the clue he wanted.

"Dr. Ihai!?"

Seeing Yi Hai's uncomfortable look, Simir immediately put down what he was holding and came to Yi Hai's side.

"No, it's fine, it's just that seeing terrible things and thinking bad things has eroded my sanity a bit... I think what the hell is going on in this world, something that might take years or even decades to investigate, I've solved a quarter of the way around. ”

Spread out the book in his hand, and pictures appeared on it, as well as paragraphs of seemingly distorted text.

[Dr. Ihai, you have watched the information about the Fallen Child, which has had a certain mental impact on you, which will affect your thinking and actions, I suggest you take a break, these things are not so easy to peep into. 】

"Fallen children? KP, do you have any relevant information? ”

[According to the remnants of the database, all the fascination of the Fallen Sons is that the Fallen Sons possess wisdom far beyond that of human beings, and they are longing for living and pure beings. 】

"Isn't this the group of monsters that Alpha said came from nowhere? What is it? ”

Since the KP is connected to the user, and there are no cluster terminals in this world to share information, Simir cannot rely on his KP to get more information, and he doesn't even know the names of these monsters.

"Fallen Sons . . . I don't have much information in my database, just a short sentence... These guys have intelligence far beyond human beings, and they have a thirst for life."

"But in that case, wouldn't it be contrary to the human record?"

“.. I think they probably never looked at humans in the eye, just as we don't look at pigs and sheep when we slaughter them. ”

The two then fell silent.

"So to speak." Simir was silent for a moment, then raised his finger and put his finger on a picture of a fallen child and said: "These guys have a wisdom far beyond that of humans, and a crazy thirst for life, but every time they appear, they only harvest a part and leave, and each time it is a ration, never exceeding or decreasing... This is very unreasonable. ”

Indeed, as Simir said, this is very unreasonable, you know, one of the main characteristics of intelligent beings is that they have themselves, and there is another remarkable characteristic of beings that have themselves, and that is selfishness. Or in other words, it is self-interest, Yi Hai does not think that such a large group of fallen children still have their own self, and their wisdom far exceeds that of humans, and they will harvest a certain amount of life every time.

No more, no less, it's simply not possible. It will not be less than this amount, and Ihai will be able to explain it, but it will not be more, and it will be constant every time. Didn't the Fallen Sons steal it? Is it possible? Impossible, then, there is only one explanation.

"They... There are chiefs, who controls them, and... Or a leader that they absolutely can't disobey, and they don't even dare to make secret moves in private, and they can't resist it... Dr. Ihai, do you have any thoughts? ”

After pondering for a long time, Simir finally came to such a conclusion, and this conclusion was actually considered by the humans of this world for a long time, but because it could not be proved and they had never won against the children of the fallen, and the plague-like thing that spread twenty years ago often smashed this world that had suffered from calamity, and they could not resist it at all.

“.. If only the black-shell book had been on me. ”

"Black Shell Book?" Simir was a little puzzled, what does this time have to do with the Black Shell Book?

"It was a book written by a mad poet of Arabia, and though the world thought it was a madman, I thought it was a great prophet and a pathetic instrument... Forget it, it's useless to say anything now .. Simir, now we're going to look for a black book that might help us get more information. ”

As a doctor of the occult, how can you do it without making trouble?

"What book?"

"The Necronomicon, since our world has survived, then this world so similar to ours two hundred years ago must also remain."

"The Book of Necronomicon", before he was summoned, Yi Hai had often heard of this book, but this book was collected in the hands of a big collector, Yi Hai had only heard it, but had never seen it, this crazy book was an absolute double-edged sword, which could bring disaster, but also hope.
