"There is survival of the fittest between the worlds."

Ryusha looked at Amakusa Shiro and said meaningfully, "And among the natural selection of the world, the world with a correct and prosperous history can be regarded as winning and gaining the right to reproduce." ”

"If it is far from the history of pan-humanity, there are huge differences, or even a world that has directly entered a dead end, it will be cut off, and this kind of parallel world will be called."

"There is only one criterion for judging between the two, that is, to see whether the current world has the possibility of upward improvement, as long as there is still the possibility of human beings in that world to move forward, then they can be attached to the tree of pan-human history."

"But once the human beings in this world can only stand still, or go directly in the wrong direction, and there is no possibility of moving forward, whether innocent or not, such a world will be cut."

After saying this, Ryuxia looked at the other party again.

"So, here's the question, Amakusa Shiro Shizhen, do you think that the world where the souls of all human beings are materialized, such a world still has the possibility of moving forward?"

Whether or not it will be selected as a pan-human history has nothing to do with the current civilization and social form of the world, but only depends on whether the world, or the overall human race, has any hope for progress.

“…… Let's assume that what you're saying is true. ”

Amakusa Shiro was stunned at first, then silent, and finally asked Ryuxia a question in a somewhat astringent voice.

"However, according to what you say, what kind of form can be said to have hope and possibility?"

"Isn't that obvious?"

Lu Xia said indifferently: "The status quo is the best, because this status quo is the most common state of countless parallel worlds, once such a world form is subverted, it will most likely enter a dead end and be cut." ”

"It's ridiculous!"

After getting the answer from Ryuxia, as if the meaning of his existence had been erased, Amakusa Shiro finally couldn't hold his breath anymore, and his tone was raised several times.

"Now in a world of war, sickness, oppression, natural disasters! Where is there anything good about a world where death and tragedy do not know when they will come? Isn't the ending of all mankind's immortality countless times better than that!? ”

Truly.

Immortality is everyone's dream, and if such a dream can be achieved, it can really be said to be a miracle and a great cause that has subverted the history of mankind, and will be admired by everyone.

"As I said, whether it will be cut or not is not necessarily related to whether the world itself is good or not."

Ryusha shook his head and continued, "Moreover, immortality is indeed a dream for individuals, but if it is extended to the human race as a whole, can it really be said to be a good thing? ”

Immortality is the greatest dream of human beings.

Whether it is interstellar navigation or survival and reproduction, all other dreams and wishes add up, and they will also regress in the face of immortality.

If a person is asked to choose between immortality and other wishes, then nine out of all the person's choice of immortality will be immortal, because as long as they do not grow old and do not die, other wishes can be fulfilled.

But just ask.

Since he is no longer old and immortal, is there still a need for other wishes?

If you don't grow old or die, is it still necessary to explore the starry sky? Is it still necessary to marry a wife and have children? Is it still necessary to care about the house? Do you still need politics and economics?

All secondary dreams and desires will become unnecessary and unnecessary.

In other words, when the greatest desires are satisfied, the entire human society loses its vitality.

That is, walking into a dead end.

"The desire to move forward is important, Shiro Amakusa."

Lu Xia said calmly: "When all desires are eliminated, that is, when the world itself enters a dead end, and at that time, you who materialize the souls of all mankind will also become the sinner who destroys the world. ”

There is no problem with the immortality of all human beings, but the problem is that once the immortality of the whole human race is achieved, the desires of human beings will be greatly eliminated, and finally nothing will be needed.

Taking Ryuxia as an example, as a ghost, he has long been immortal, but the reason why he has not become numb so far is that he wants to gain affection.

But if he doesn't have emotional problems at all, he is a normal person, and if he achieves immortality, what will he do now?

Game world? Wandering the red dust?

That's a polite way to put it.

To put it mildly, it's just a salted fish, and I don't even bother to turn it over.

And if all mankind is playing the world and wandering the red dust...... It's scary to think about.

It cannot be ruled out that a small number of people are still enterprising, but when the time comes, ninety percent of human beings will lose their desire to improve.

Amakusa's face became very gloomy.

The emotions in his heart were tumbling and surging rapidly.

If what Ryusha said is true, then he, who made this world a fixed thing, will indeed become a sinner who destroys the world.

It's funny that he did a good deed and a great deed that could fulfill everyone's wishes, but in the end, it would lead to the whole world being buried for it? It doesn't get any funnier than that!

“…… Where can you prove the truth of this statement? ”

A slight struggle and hesitation appeared on Shiro Amakusa's face.

He had obviously listened to Ryuxia's words, but he had spent sixty years planning the materialization of the souls of all mankind, and he couldn't give up easily just because of Ryuxia's words.

Even if he is to be stopped, he must come up with evidence that convinces him.

"Nope."

Ryusha shook her head.

"I'm afraid that even the clock tower doesn't know this theory, even if it's a heroic spirit, there should be very few people who know about it, after all, it involves many parallel worlds...... You might want to ask the Second Magician, the Jeweler? ”

The second magic is parallel world interference.

The one who holds this magic is the legendary jewel Honzerridge, and there is only one jewel in countless parallel worlds.

However, now that I think about it, maybe the jewel is the operator of countless parallel worlds?

"Speaking of which, it will take a lot of time to materialize the souls of all human beings, right?"

Ryuxia didn't dwell on this issue any longer, but asked again to Amakusa Shiro, "How long will it take?" ”

“…… It could take decades. ”

Amakusa Shiro lowered his head, obviously in the mood to answer his question, so he just gave an approximate number.

"yes, that's a shame...... I won't bother you to think, farewell. ”

Ryusha glanced at him, then shook his head again, turned around, and disappeared into the temple.

But before it disappears.

Ryuxia took out another rune stone and silently threw it under the Great Holy Grail, then disappeared into obscurity.

Shiro Amakusa, who was immersed in thoughts, didn't notice Ryuxia's movements at all.
