People have a long history in their understanding of four dimensions and have had countless hypotheses.

The most famous one is superstring theory, which directly determines that there are eleven dimensions of the universe.

In superstring theory, zero dimension is a point without length, width, and height. One dimension is a line without width and height. Two dimension is a plane without height. Three dimension is a space with length, width and height.

At this point, people's perceptions are basically the same.

But from the fourth dimension, everything became a conjecture.

Superstring theory believes that the fourth dimension is time.

This is easy to judge, because one dimension is actually an infinite extension of a point in the zero dimension in one direction. Two dimensions extend infinitely to another spatial angle, and three dimensions extend infinitely to the plane towards the third dimension.

From this logical analysis, the fourth dimension must also extend infinitely in the fourth direction.

But where is this direction? There are questions.

Because people cannot perceive the fourth dimension.

No matter how big the universe is, it is a three-dimensional cube in people's eyes, and it 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 big it is, the paper is still two-dimensional, and it has no third dimension.

The fourth dimension must be the set of all three-dimensional dimensions in this dimension, and is the infinite extension of the three-dimensional dimension towards the fourth dimension.

So in which direction does the third dimension extend to form the fourth dimension?

There are many different opinions.

In superstring theory, the fourth dimension is time, because it is the only common direction of movement of the entire three-dimensional dimension that people can perceive. If time is four-dimensional, then it does contain all three-dimensional in this field.

But there are also oppositions, believing that time is a separate dimension, just like two vertical and horizontal lines interleaving. Time can be interleaved with three-dimensional, or two-dimensional and one-dimensional.

If you agree that time is the fourth dimension, you think this statement is wrong, because all two-dimensional and one-dimensional dimensions are also included in the three-dimensional space. It is incorrect to determine that time exists independently.

But it cannot explain another problem, which is the irreversible problem of time.

The space itself is reversible, just like a scroll spread out into a painting, it can also be retracted. Therefore, the space can be folded.

But time doesn't work. It describes the trajectory of things. Once this trajectory is produced, you can't look back.

Therefore, although time has been described together since ancient times, they are actually completely different in nature.

Space is a real existence, and although irrespectable, it exists at the actual 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.

The superstring theory based on this paradox is meaningless in the five-dimensional and six-dimensional dimensions to the eleven-dimensional dimensions.

So where is the fourth dimension?

After the arrival of the gods, human scientists after a long period of verification, they believed that it was in the space itself.

Just as low-dimensional creatures cannot understand high-dimensionality, being unable to understand does not mean that they do not exist, nor does it mean that they cannot perceive. It is just that all perceptions of four-dimensionality have been three-dimensionally transformed.

It's like an ant climbing up a big tree from the ground. It's clearly walking through a three-dimensional space, but its perception is flat.

The same is true for humans. We travel in four dimensions because we cannot perceive it, so the journey is long.

The real four-dimensional itself has countless shortcuts because it is built on space.

Those gods are undoubtedly able to sense four-dimensional creatures, so they established the gates of other worlds, which are actually far lower than imagination, because in their eyes, the so-called millions of light years may not be that far. From the perspective of four-dimensionality, it may be just a piece of paper.

It is precisely because of this that it is easy to "draw holes" and may not require origami at all, or fold them only a little bit.

After understanding this point, looking back at the Qingkong tribe, many problems will be solved.

For example, although the Qingkong tribe's blue core can emit a magnetic field to affect the space, this is actually not the most important thing.

Most importantly, it is used to perceive the fourth dimension.

When you can perceive the fourth dimension, the use of space at the three-dimensional level will become much simpler and easier.

This cognition is not complicated, but it is like a stepping stone, which really opens the door to cognition for Yuan Chenfei.

Once some things are broken, it will become much easier to understand.

Understanding is a breakthrough!

At this moment, with his continuous analysis of the Qing core in his hand, the Qing core quickly disappeared at a speed visible to the naked eye.

It is not about absorbing power, but about Yuan Chenfei's analysis, which is directly completely decomposed, just like dissection.

What Yuan Chenfei had to do next was simple. He analyzed all the green cores in his hand one by one, and the speed was extremely fast.

Until the last green core disappeared, Han Feiyu could feel that Yuan Chenfei's temperament seemed to have changed.

"How is it?" Han Feiyu asked excitedly: "Is there a breakthrough?"

"Yeah." Yuan Chenfei replied: "My super-sensing range has been enhanced."

"That's it." Han Feiyu immediately pulled down his face.

Yuan Chenfei smiled: "This is just the beginning, the key is to perceive the four-dimensionality. This is a gradual process. As perception increases, the understanding of space will deepen. But this is not the point, the point is... there is a way out!"

There is a way out!

In the past, Yuan Chenfei wanted to break through the space, but there was no way out.

Now he has a way to go.

This is the most important thing.

As long as there is a way, the next thing to do is to keep going.

No matter how far you go, those understandings will not be in vain, but will be combined with his existing system.

Now it is enhanced super sensing, and later it may be duel space, teleportation, and even hypnosis.

As for now...

Yuan Chenfei stood up and said, "I'm going to deal with those Qingkong tribes."

Kill, harvest, and enhance.

The goal suddenly becomes extremely simple.

Han Feiyu said, "Don't worry, I'm here."

"Oh? How are you doing here?" Yuan Chenfei asked.

He did not forget that Han Feiyu's mission was the main point.

"Oh, there are a lot of troubles." Han Feiyu shook his head: "Now the city wall has been completed, and infrastructure such as residential areas and palaces are also being built. The problem now is that there are not enough resources."

“Tell me.”

Han Feiyu took out the map: "Infrastructures such as residential areas, alchemy towers, energy towers, royal palaces, and temples can be built with ordinary bricks and wood. But those special buildings require special resources. Oh, I can see that this is a farming game, and it is invincible with heroes. Basic buildings are ordinary resources, just with wood and stone. However, special buildings and higher buildings all require special resources. This requires us to take the initiative to go out and find them, fight along the way, level up, and collect resources, and not one of them is missing."

Yuan Chenfei also laughed: "So, are you really planning to build all those special buildings? Are you not afraid of your opponents attacking you in big ways?"

"Hey, you didn't see it this time. This is actually a trap set by the gods." Han Feiyu said proudly.

"Oh?" Yuan Chenfei was intrigued.

There are always traps in the Gods' mission, and there is no doubt about this. However, because Yuan Chenfei had paid attention to the breakthrough in space before, he ignored this.

Unexpectedly, Han Feiyu saw it first this time.

Han Feiyu said: "On the surface, we build special buildings to give our opponents a chance to increase troops, but in fact, if we adopt conservative approach, we will definitely be deceived by the gods. I am sure that even if we don't build a special building, after a month, the Qingkong tribe will attack more than 70,000 troops."

Yuan Chenfei pondered for a moment: "It's clear."

"First, the mission only says that the Qingkong tribe cannot attack the territory within one month, but it doesn't mean whether the Qingkong tribe can attack in a month."

"Hmm?" Yuan Chenfei's eyes lit up: "So do you think they will invite reinforcements?"

"There is a possibility, but not just. The second point is why the Qingkong tribe fights with us? Hundreds of square kilometers of land are small, not big. But considering the reputation of our human tribe and you now, they are really confident that they can win it with the same amount of troops? If you are not sure, why should we fight with us?"

Hearing this, Yuan Chenfei began to ponder.

The second point Han Feiyu said seems simple, but it actually means a lot.

In this mission to build a country by Cyclops, Yuan Chenfei chose to establish a territory in the Qingkong tribe, mainly because the Qingkong tribe was treasonous at the time.

But the reason why the Qingkong tribe was betrayed was not only because the goblin tribe gave enough benefits, but also because the goblin tribe had no problem with the response strategy at that time, and they believed that the goblin tribe could win.

Being able to win! The key is.

Therefore, after the demise of the Goblin Clan, it is impossible not to be nervous due to the situation of the Qingkong Clan.

The reason why Han Feiyu was sure of this was what Qu Wei told him that shortly after the demise of the Goblin Clan, the Qingkong Clan came to seek peace.

As a normal situation, everyone must have arguing about the compensation issue.

But what I didn't expect was that the Qingkong tribe disappeared shortly after the discussion.

They gave up on peacekeeping.

You can do whatever you want.

This made the upper class of the human race at that time very puzzled. What's wrong with this?
