Just like the three-dimensional space relative to the two-dimensional space, the four-dimensional space also has a closest point to the three-dimensional space. For example, there is a small ball on the two-dimensional plane, which represents the two-dimensional distance.
The white paper in the world is one decimeter away. So, in the two-dimensional world represented by this white paper, the point closest to the object in the three-dimensional world is undoubtedly directly under the small ball.
.
Because only directly below the small ball is the vertical distance between the two, and the vertical distance is the shortest distance. Any point that deviates directly below the small ball will not form a two-dimensional plane perpendicular to the small ball.
Straight lines and the distance between them are not the shortest distance.
From this we can know that in the three-dimensional world, there must be a point closest to the object in the four-dimensional world. This point is on the scale of the four-dimensional space, and in the fourth dimension, this straight line is vertical
in three-dimensional space.
Although creatures in the three-dimensional world cannot specifically imagine and understand the magic of the four-dimensional space, the specific position of the point closest to the object in the four-dimensional space and the three-dimensional world can be inferred through mathematical methods. In fact, this mathematical method is not complicated.
, Level 4 civilization can also get the answer very easily.
In this way, the biggest premise is met, that is, the dwarves of the fourth-level civilization can also find the entrance to the ruins of the Tolor civilization through this method. After all, the ruins of the Tolor civilization are left to
Of the dwarves.
Xiao Yu only performed calculations for a very short period of time before he came to the conclusion. During the calculation, Xiao Yu had already marked the position of this point in the three-dimensional image.
"What a magical thing this is." Xiao Yu sighed in his heart. Creatures in the three-dimensional world cannot detect the existence of the fourth dimension, nor can they make an intuitive guess about the fourth dimension. Human beings cannot
Just like imagining a cup, a table or something like that, you can clearly imagine what the fourth dimension is, but through the tool of mathematics, you can clearly express it.
"Then it's decided." Xiao Yu said, "I will take our fleet and rush to the reservation location within the reservation time."
"Master, I think there is no need for you to take the risk yourself. You only need to send an intelligent creature as the leader, and then allocate some combat forces to follow. You must understand that we are not going to fight. We are not going to fight.
The purpose is just to obtain the relics of the Trol civilization." After Xiao Yu announced the subsequent action plan, a scientist suggested.
Xiao Yu only thought for a moment, then controlled his phantom and shook his head slightly: "In this ruins, the relics of Tolor civilization are very important to me. Only by going there in person can I have the greatest certainty.
Get it. What's more, according to my deduction, the chance of encountering catastrophe in this operation is only 6%. In other words, the chance of our safety is 94%. This is completely worth it.
Let’s take a risk. After all, this is just a ruins, not a battlefield.”
Seeing Xiao Yu's determination, the scientist stopped talking. In fact, Xiao Yu understood its thoughts very well. For the purpose of controlling these intelligent and civilized creatures, Xiao Yu gave up all control authority of all spacecrafts.
It is in his own hands. As long as he dies, all intelligent and civilized creatures under his control will also die. This scientist is obviously worried about this problem, so he does not want Xiao Yu to take risks.
After all, their lives depend on Xiao Yu.
But Xiao Yu has deeper considerations. Until now, Xiao Yu cannot fully believe in the loyalty of these alien intelligent creatures. Under his control, of course, there is no need to worry about the loyalty of these creatures, but what if they are out of his control?
Who knows, after entering the so-called new world, whether these spacecraft can still be controlled by themselves? In Xiao Yu's inference, there is a high probability that long-distance communication is not applicable to four-dimensional space. So, in order to avoid
For this problem, Xiao Yu needs to authorize them to have complete control of the spacecraft, and then they enter the ruins. If they are really lucky, they can obtain the weapon called split space, and then control the spacecraft to escape from the ruins again.
, what should I do if I rely on this weapon to deal with myself?
The huge difference between civilization levels makes Xiao Yu unsure of relying on his current strength to fight against a spaceship equipped with level 6 civilization weapons, even if there is only one such spaceship.
So Xiao Yu chose to take a risk himself.
There are other benefits to this choice. Xiao Yu, who has huge computing power, is always much stronger than other intelligent creatures. If you go there in person, you have the best chance of successfully obtaining these relics of Tolor civilization.
After considering all kinds of considerations, Xiao Yu chose to go there himself.
"Then let's do this. I will lead all the spaceships to arrive at the predetermined location in three days. If possible, we will all enter the ruins." Xiao Yu announced his decision.
The scientists who heard Xiao Yu's decision had different expressions, some were calm, some were worried, and some were excited. Xiao Yu looked at these different expressions without any fluctuation in his heart.
Various orders have been issued, and Xiao Yu's fleet quickly completed the assembly and rushed to the predetermined location. Since it was close to the star and could not conduct curvature navigation, this voyage was a conventional sublight voyage.
Seeing the huge star that was constantly changing its trajectory as if suffering from epilepsy getting closer and closer, Xiao Yu's heart remained calm as usual.
The arrival of a message made Xiao Yu's mood fluctuate a little. Xiao Yu secretly thought: "This guy is still following me."
Yes, this message is about the fourth-level alien beast. The detection data shows that after Xiao Yu's huge fleet began to set off towards the intended target, this guy also began to move his position and continued to follow Xiao Yu loomingly.
behind.
"You have been following me for hundreds of years...it's time to end it." Xiao Yu smiled coldly in his heart, "After getting a weapon like splitting space, let me see where you can run."
Xiao Yu's current weapon system is actually not advanced compared to Xiao Yu's technological level, at least it is a little worse than the Molian civilization. Xiao Yu believes that if he really obtains a space weapon from a sixth-level civilization,
Your own shortcomings will be fully compensated.
"At that time, I will have four protective shields for defense and space weapons for attack. In this galaxy, besides the sixth-level civilization, who else can pose a threat to me? It's just a small fourth-level alien beast.
It’s not worth mentioning.”
After a few days of regular sailing, Xiao Yu's fleet has arrived at the scheduled location. A series of orders were issued. The robots and leaders of various tribes faithfully fulfilled Xiao Yu's orders, such as raising the alert level, appeasing their respective tribesmen, and allowing
No matter what situation they encounter, don't panic.
Because Xiao Yu and Luca II speculated that the dwarves would be the key to opening the door to the new world, Xiao Yu made special arrangements for this, relaxing the concealment of the forty Homeship spacecraft, and specifically letting them
It was exposed. Regardless of whether it is useful or not, Xiao Yu believes that doing it is better than not doing it.
"Okay, let's start waiting." All the preparations have been completed. The rest, whether the specific method of entering the ruins is as expected, can only be left to the control of God.
Time passed bit by bit, and everything in the starry sky was silent as usual. There were no planets, no comets, no asteroids, only the huge star that was bright as usual, facing the void of the universe, emitting light in vain.
own heat.
Xiao Yu's thoughts drifted far away.
Xiao Yu began to think about a question, a profound question, that is, what is all this for? What is the meaning?
Whether this star emits heat, or even exists, it will not have any impact on the outside world. It is insignificant and ignored. At the same time, it has no consciousness. So, why does it exist?
Not only this star, there are many such things in the universe. It doesn't matter whether they exist or not, but they do exist. Xiao Yu can't figure out why all of this exists.
Perhaps existence itself is a kind of meaning? Or, is there really an omniscient and omnipotent God in the universe, controlling everything in secret?
Humans in the Earth Age have already begun to think about this question, but until they became a level five civilization, Xiao Yu still did not come up with the answer to this question.
"The universe is vast, and there are so many secrets hidden in it. Whether it is natural science or humanistic philosophy, there are many questions waiting for me to explore. Perhaps, the meaning of the existence of intelligent creatures is here, constantly evolving.
During the exploration, I solved one unknown after another, and at the same time, I came into contact with more unknowns, and then launched a new round of exploration until the end of my life. But my existence is not limited by time. If nothing unexpected happens,
I will have an infinite lifespan, so what is the meaning of my existence?"
A sudden message interrupted Xiao Yu's thoughts and brought Xiao Yu back to his senses.
"My people, welcome to the world of Tolor."
While waiting quietly, the relic that kept changing its position quietly arrived. The moment it arrived at the scheduled time, Xiao Yu received such a message in his brain. (To be continued...)
