People's understanding of the four dimensions has been around for a long time, and there have been numerous hypotheses.
The most famous one is superstring theory, which directly establishes that there are eleven dimensions in the universe.
In superstring theory, zero dimension is a point with no length, no width, and no height. One dimension is a line with no width and no height. Two dimensions are a plane with no height. Three dimensions are space with length, width, and height.
At this point, people's perceptions are basically the same.
But starting from the fourth dimension, everything becomes conjecture.
Superstring theory believes that the fourth dimension is time.
This is easy to judge, because one dimension is actually formed by a zero-dimensional point extending infinitely in one direction. Two-dimensional is the infinite extension of one dimension toward another spatial angle, and three-dimensional is the infinite extension of a plane toward the third dimension.
From this logical analysis, the fourth dimension must also extend infinitely in the fourth direction from the three dimensions.
But where is this direction? But there are questions.
Because humans cannot perceive the fourth dimension.
No matter how big the universe is, it is still a three-dimensional cube in people's eyes. This has nothing to do with size.
No matter how big it is, it is still three-dimensional. Just like a piece of paper can be larger than a Rubik's Cube, but no matter how large it is, the paper is still two-dimensional and has no third dimension.
The fourth dimension must be the set of all three dimensions within this dimension, and it is the infinite extension of the three dimensions toward the fourth dimension.
So in which direction does the third dimension have to extend to form the fourth dimension
Opinions vary.
In superstring theory, the fourth dimension is time, because it is the only common direction of motion that people can perceive in the entire three dimensions. If time is four dimensions, then it does include all three dimensions in this realm.
But there are also objections, believing that time is a separate dimension, just like two vertical and horizontal lines intersecting. Time can intersect with three dimensions, or it can intersect with two and one dimensions.
Those who agree that time is the fourth dimension think this statement is wrong, because three-dimensional space also includes all two- and one-dimensions. It is incorrect to assume that time is another dimension that exists independently.
But it cannot explain another problem, which is the irreversibility of time.
The space itself is reversible, just like a scroll that is unfolded into a painting and can be taken back again. So the space can be folded.
But time is not good. It describes the trajectory of things. Once this trajectory is created, there is no turning back.
For this reason, although time has been described together since ancient times, in fact they are essentially completely different.
Space is a real thing. Although it is elusive, it exists on a practical level.
Time is a concept. According to Einstein's theory, if there are no elementary particles in space, time will not exist.
So time cannot be folded.
In the superstring theory based on this paradox, the following five, six, and eleven dimensions are meaningless.
So where is the fourth dimension
After the arrival of the gods, human scientists have verified for a long time that they are in space itself.
Just like low-dimensional creatures cannot understand higher dimensions, being unable to understand does not mean that they do not exist, nor does it mean that they cannot be perceived. It’s just that all perceptions of four dimensions have been made three-dimensional.
Just like an ant climbing up a tree from the ground, it obviously walks through a three-dimensional space, but to its perception, the world is flat.
The same goes for humans. We travel in the fourth dimension, and because we can’t sense it, the journey is long.
The true fourth dimension itself has countless shortcuts because it is built on space.
There is no doubt that those gods are creatures that can perceive the fourth dimension, so the door they built to other worlds is actually far lower than imagined, because in their eyes, the so-called tens of millions of light years may not be that far at all. From a four-dimensional perspective, it may be just a piece of paper.
It is precisely because of this that it is easy to "punch holes". There may be no need to fold the paper at all, or it may only be folded a little.
After understanding this, looking back at the Blue Sky Clan, many problems will be easily solved.
For example, although the blue core of the Blue Sky Clan can emit magnetic fields and affect space, this is not actually the most important thing.
Most importantly, it is used to perceive the fourth dimension.
When you can perceive the fourth dimension, the use of three-dimensional space will become much simpler and easier.
This knowledge is not complicated, but it is like a stepping stone that really opens the door to knowledge for Yuan Chenfei.
Once some things are revealed, they become much easier to understand.
Understanding is breakthrough!
At this moment, as he continued to analyze the blue core in his hand, the green core quickly disappeared at a speed visible to the naked eye.
Instead of absorbing power, Yuan Chenfei directly decomposed it completely during the analysis process, just like dissecting.
What Yuan Chenfei had to do next was simple. He analyzed all the blue nuclei in his hand one by one, and the speed was surprisingly fast.
Until the last blue core disappeared, Han Feiyu could feel that there seemed to be some changes in Yuan Chenfei's temperament.
"How's it going?" Han Feiyu asked excitedly, "Has there been a breakthrough?"
"Yes." Yuan Chenfei replied: "My super-sensitive range has been enhanced."
"That's it." Han Feiyu immediately grimaced.
Yuan Chenfei smiled: "This is just the beginning. The key is to perceive the four dimensions. This is a gradual process. As the perception increases, the understanding of space will deepen. But this is not the point. The point is... there is a way!"
There is a way!
In the past, Yuan Chenfei wanted to break through the space, but had no way to find it.
Now he has a way out.
This is the most important.
As long as there is a road, the next thing to do is to keep walking.
No matter how far he goes, those insights will not be in vain, but will be integrated with his existing system.
Now it's enhanced super-sensing, but later it may be duel space, teleportation, or even hypnotic illusion.
As for now…
Yuan Chenfei stood up: "I'm going to deal with those Qingkong tribe."
Kill, harvest, improve.
Goals suddenly become easier than ever.
Han Feiyu said: "Don't worry, I'm still here."
"Oh? How are you doing here?" Yuan Chenfei asked.
He also didn't forget that Han Feiyu's mission was the most important task.
"Oh, there are a lot of troubles." Han Feiyu shook his head: "Now the city wall has been completed, and residential areas, palaces and other infrastructure are also being built. The problem now is that there are not enough resources."
"Talk about it."
Han Feiyu took out the map: "Infrastructure such as residential areas, alchemy towers, energy towers, palaces, and temples can be built with ordinary bricks and wood. But those special buildings require special resources. Don't tell me, I can figure it out. Well, this is a farming game, and it is somewhat similar to Invincible Heroes. The basic buildings are ordinary resources, just wood and stone. But special buildings and high-level buildings all require special resources. This requires us to take the initiative to go out and find them. Fight, level up, and collect resources along the way, no one is missing."
Yuan Chenfei was also happy: "So, do you really plan to build all those special buildings? Aren't you afraid that your opponents will invade in large numbers?"
"Hey, you didn't see it this time. This is actually a trap set by the gods." Han Feiyu said proudly.
"Oh?" Yuan Chenfei became interested.
There are always pitfalls in the missions of the gods, there is no doubt about this. However, Yuan Chenfei ignored this because he had previously focused on space breakthroughs.
Unexpectedly, Han Feiyu noticed it first this time.
Han Feiyu already said: "On the surface, our construction of special buildings is an opportunity for our opponents to increase their troops, but in fact, if we take a conservative approach, we will definitely be tricked by the gods. I am sure that even if we build a special building If we don’t even build one, after one month is up, the Qingkong Clan’s attacking troops will definitely exceed 70,000.”
Yuan Chenfei pondered for a moment: "Explain clearly."
"First, the mission only states that the Blue Sky Clan is not allowed to attack the territory within one month, but it does not say whether only the Blue Sky Clan can attack after one month."
"Huh?" Yuan Chenfei's eyes lit up: "So you think they will invite reinforcements?"
"It is possible, but not limited to it. The second point is, why should the Qingkong people fight against us? The land of hundreds of square kilometers is neither small nor big. But considering the prestige of our human race and yours, they Are you really confident that you can win with the same number of troops? If you are not sure, then why are you fighting us?"
Hearing this, Yuan Chenfei became thoughtful.
The second point mentioned by Han Feiyu seems simple, but it is actually of great significance.
In this Cyclops nation-building mission, Yuan Chenfei chose to establish a territory in the Qingkong Clan. The main reason was that the Qingkong Clan had betrayed their faith.
But the reason why the Qingkong Tribe broke their trust was not only because the Goblins had given enough benefits, but also because the Goblins’ response strategy at that time was not problematic, and they believed that the Goblins could win.
Can win! That's the key.
Therefore, after the demise of the Goblin clan, it is impossible not to be nervous based on the situation of the Blue Sky clan.
The reason why Han Feiyu was sure of this was because Qu Wei told him that not long after the Goblin clan was destroyed, the Qingkong clan came to seek peace.
Under normal circumstances, everyone would definitely have to argue and discuss the issue of compensation.
But what I didn't expect was that not long after the discussion, the Qingkong clan disappeared.
They gave up asking for peace.
Just do whatever you want.
This made the upper echelons of the human race at that time very confused. What was wrong with this
But the goblins were newly destroyed and Pepsi was troubled, so they didn't think much about it.
It was not until the Cyclops nation-building mission began that Yuan Chenfei chose to establish a nation in the territory of the Blue Sky Tribe, and the upper echelons of the human race remembered this.
They were keenly aware that there might be a connection between the two.
Several discussions were held for this purpose, and finally a conclusion was reached - this was also an important reason for Qu Wei to come here.
"What conclusion?" Yuan Chenfei asked.
"This may be a two-way mission." Han Feiyu replied.
"Two-way mission?" Yuan Chenfei was surprised.
"Yes!" Han Feiyu replied: "The Qingkong clan wanted to sue for peace at first. The superiors didn't want to have another enemy, so they offered a compensation price that they thought was not excessive. But unexpectedly, they didn't even talk about it later. The request for peace was terminated. The superiors did not understand it at first, but later combined with the Cyclops founding mission, they thought it was probably because of the relationship between the gods. They assigned tasks to us, and also assigned tasks to the Blue Sky Tribe, making it impossible for them to seek peace. ."
"Has there been any precedent for such a two-way mission before?"
"Yes, but not many. That's why they didn't expect it at first. But what is certain is that if the Qingkong tribe also has missions, then their troop limit is not necessarily unbreakable. Once they can complete multiple missions, The increase in troop strength may be far greater than expected. Also because of the mission, they must go all out for this territory."
"Oh no!" Yuan Chenfei cursed: "The promised wish task is very simple?"
Han Feiyu gave a very philosophical answer: "The task is very simple, but the gods are very complicated."
