After figuring it out a little, the rest is not difficult.

"You are indeed very smart, at least prove that my choice is not wrong."

"Your choice?"

The girl smiled and said, "Do you think that you were able to obtain this special body by chance?" ”

Chu Tianjiang was shocked again. "You...... You mean......"

"That's right, if I hadn't chosen you, you wouldn't have been able to enter the Y Celestial Body at all, and you wouldn't have been able to obtain the body of this pure energy body. You've figured out the most critical questions, it's just that your thinking is very confused. The girl picked up the purple sand cup and put it in front of Chu Tianjiang. As you guessed, if the civilization in the micro-universe is the 'micro-civilization', then it is the 'big civilization' that created the micro-universe. We are a great civilization, and it is relative to the 'micro' and 'big', not absolute, and there are 'giant civilizations' that have become extinct above us. As with micro-civilizations, large civilizations are not the only ones, but there are many, both coexisting and hostile. ”

"The great civilization that coexisted with you also created the micro-universe and evolved the micro-civilization?"

The girl nodded and said: "More importantly, we are a micro-universe created in the same universe, and some of the micro-civilizations created by hostile giant civilizations have evolved to an extremely high stage, and their scientific and technological strength far exceeds that of human beings, and these micro-civilizations will come to the micro-universe of human beings sooner or later." ”

"And then?"

"We can only create a micro-universe, not a universe, and the universe itself is finite, and the resources we have in the universe are also limited."

"For this reason, the invading micro-civilization will wipe out the human race, and then occupy the human micro-universe?"

"Do you think there is anything else possible?"

Chu Tianjiang let out a sigh, although he knew that what the Dao girl said was true, but he didn't want to believe it at all.

"Believe, or not believe, is you, not me. But the impact of believing or not believing is not up to you and me. ”

"Trust is also mutual, not one-sided."

"You're really smart."

Chu Tianjiang smiled and said, "Since you let me come here, instead of imprisoning me in a black hole, you won't just want to find someone to talk to, right?" ”

The girl also smiled and said, "You're right, trust is indeed mutual, and I'm not telling you this to find someone to say. ”

"Then you have to trust me before I can trust you."

The girl nodded, pondered for a while, and said, "The biggest difference between a micro civilization and a big civilization is the dimension of the space where it is located. The current micro-civilization exists in the three-dimensional universe, while the great civilization exists in the four-dimensional universe. It is not the four-dimensional universe that you think of, that is, it does not add a two-way time dimension, but adds a dimension in space, which is equivalent to a collection of countless three-dimensional universes. ”

Chu Tianjiang didn't say much, because he had already thought of this.

"In any dimension of the universe, there is more than one civilization. In the four-dimensional universe, there used to be countless great civilizations in the three-dimensional universe like the current three-dimensional universe. Like the current micro-civilizations, the great civilizations need more and more resources and living space when they evolve, and wars will inevitably break out between the great civilizations, and the war will accelerate the speed of evolution. When science and technology develop to a certain extent, something will happen. ”

"What's the matter?"

The girl hesitated a little and said, "War is only a means, and the end is the same, that is, to destroy the enemy and seize the resources controlled by the enemy. The problem is that war also consumes resources. After a long war, in the end, only seven major civilizations remained, and the scientific and technological strength of the seven major civilizations was comparable. If the war continues, it will soon deplete the resources in the four-dimensional universe, so we must try to reduce the consumption of the war and retain the next part of the resources that are enough for us to survive, and there is only one way. ”

"What?"

"Dimensionality reduction."

Chu Tianjiang was stunned for a moment, and then looked at the girl in disbelief.

"To put it more bluntly, it is to reduce one dimension of space and reduce the four-dimensional universe to a three-dimensional universe. Maybe you think this is impossible, but that's because your technology isn't advanced enough. In the war of cosmic civilization, the most powerful weapon is to change the basic laws of the universe. The seven great civilizations thought of this method almost at the same time, and almost simultaneously developed the technical means to reduce the cosmic dimension. ”

"And then?"

"It's a pity that if the four-dimensional universe doesn't exist, we don't exist either. If one day, the technological civilization of mankind reaches this level and masters the technical means to reduce the dimension of the universe, you will also face the same problem, that is, human beings can never become intelligent life in the two-dimensional universe. ”

"It's just that your wisdom can endure, so you need a carrier of wisdom."

The girl smiled and said, "You are indeed very smart, and this is the reason why we created the microverse. It's just that you don't need to worry, we have created countless micro-universes, and in these micro-universes we have evolved life, so that life can produce wisdom through natural evolution, and human evolution is not thorough enough, not the most ideal carrier of wisdom, so it is not our first choice. ”

"So, you can spare the humans?"

"With all that said, do you still think I'm going to destroy humanity?" The girl sighed and said, "Even if we don't regard humans as carriers of wisdom, we won't allow the micro-universe where humans live to be controlled by hostile civilizations. Unfortunately, dimensionality reduction has just begun, and we are not the first great civilization to carry out dimensionality reduction, so we are powerless to protect all micro-universes, and can only help micro-civilizations like humans resist invasion. Don't forget, resources in the three-dimensional universe are even more scarce, and any one microverse is extremely important. ”

"Speaking of which, you still feel like you're helping humanity."

"Isn't it?"

Chu Tianjiang sighed and said, "Then let's talk about a substantive issue." If you are willing to help humanity, and the micro-civilizations created by other great civilizations are about to invade the solar system, then why don't you directly deal with the invaders and buy more time for humanity to evolve? ”

"We can't directly deal with the micro-civilizations created by other great civilizations."

"For what?"

The girl sighed and said, "The four-dimensional universe is about to collapse, and the seven great civilizations must join forces to reduce the four-dimensional universe as a whole to a three-dimensional universe. For this reason, the seven major civilizations have reached an armistice, and before the completion of dimensional reduction, there will be no more wars for resources, and this includes the micro-universe in the three-dimensional universe. You are intelligent beings that have evolved naturally in the micro-universe, and therefore you have the right to defend your micro-universe against invaders. If we intervene in the war between micro-civilizations, it will inevitably lead to a war between the great civilizations, leading to the failure of the overall dimensionality reduction of the four-dimensional universe. This not only means that the seven great civilizations will perish, but also that the three-dimensional universe will collapse before it stabilizes, so all the micro-universes in the three-dimensional universe will be wiped out in an instant. ”

"I'm afraid it's not that simple, is it?"

"You've thought of it. As you guessed, the technology of all micro-civilizations is very backward, even if a war breaks out between micro-civilizations, even if the perseverance to maintain the stability of the micro-universe is destroyed, because the resources in the micro-universe have not disappeared, so it will not have any impact on the three-dimensional universe. To use a simple analogy, even if the wolf eats the sheep, the meat grows on the wolf, and the total amount does not decrease because the wolf eats the sheep. ”

"Doesn't the wolf consume a portion of the mutton?"

The girl smiled and said, "This analogy is not quite appropriate. The fact is that when the wolf eats the sheep, it is equivalent to obtaining all the meat of the sheep, and even if a part of the meat is consumed, it will be converted into other forms of resources, such as the heat dissipated, so the total amount of resources has not decreased. Only when science and technology reach a certain level will resources be consumed in war, and at this time, the micro-civilization is already a great civilization. ”

"How far are humans from that?"

"Very far away, almost out of reach."

"In this way, humanity is hopeless."

The girl smiled and said, "Before the destruction, any micro-civilization has the possibility of developing and growing, because the explosion of science and technology may come at any time. ”

"In that case, why can't we give humanity a chance?"

"Don't you think this is an opportunity?"

Chu Tianjiang smiled and said, "What you told me, there is an extremely serious problem. That is, if the seven civilizations are forbidden to intervene in the war between the micro-civilizations, it will definitely be forbidden to provide technical assistance to the micro-civilizations, so you can only help humans to speed up their evolution, but you will not be able to provide advanced technology to humans. Without advanced technology, do you think humanity will be able to defeat the impending invasion? ”

The girl was silent, because what Chu Tianjiang said was indeed the truth.

"What's worse is that your so-called help is stifling human creativity, making everyone pin their hopes on you and lose the motivation to create." Chu Tianjiang sighed and said, "You should know that the existential crisis is the source of human creativity. ”

"You're right, and it's not just humans."

"In that case, why don't you give humanity a chance."

"What chance?"

"The explosion of technology."

"You're saying that let me stop interfering with human beings, let human beings evolve naturally, and strive to achieve a technological explosion?"

"You've intervened enough, and I'm sure humanity will have a technological explosion."

The girl sighed and said, "Do you know how much time there is left for the human race?" ”

"How much?"

"One grid!"

"What?"

"This is a unit of time in the four-dimensional universe, which is equivalent to one second of yours, but in the three-dimensional universe, there are almost a hundred years."

"Didn't you start by saying that human beings are only a hundred years behind other micro-civilizations?"

"But this does not mean that human beings will be able to catch up with other micro-civilizations in a hundred years."

"Well, if humanity achieves a technological explosion, is there any certainty that it will defeat the invading micro-civilization?"

The girl pondered for a moment, then nodded, and said, "I can agree to your request, but you must also agree to one of my requests. ”

"Say, what are the requirements? I've known for a long time that you're talking to me about this for some other purpose. ”

"After humanity has achieved a technological explosion and gained enough strength to resist invasion, you have to give up your self-consciousness and give yourself to me."

"If you want my body, you can take it now."

"Not now, it's too early. In addition, you are one of the key figures in the realization of humanity's technological explosion, so you have to stay in this micro-universe. ”

"In that case, send me back now."

"Where do you want to go back?"

"You know the way."

Seeing the girl smile, Chu Tianjiang closed his eyes.

Although the process was not quite the same as Luo Jinyong expected, the ending was indeed as Luo Jinyong expected, and the crisis was resolved in a compromise way.
