In Feng Qian's courtyard, Ah Ge and Feng Whisper stayed for three whole days, except for the first day when Ah Ge was learning Ling Feng's sword technique, the remaining two days, Ah Ge was comprehending Feng Qian's "sword intent", a kind of indescribable artistic conception.

"Sword intent", a kind of artistic conception that cannot be inherited and taught, the artistic conception that kendo warriors dream of, with this artistic conception, not only can learn swordsmanship with half the effort, but also be able to enter the Tao with a sword and comprehend the "law".

"Law" is a kind of power that only the peerless strong can have, and it can already communicate the "rules" between heaven and earth, so as to formulate its own "laws".

"Peerless powerhouses, they are not gods, but they have learned some of the power of gods, and they have touched the edge of transcending the rules of heaven and earth, and have the power to pass through heaven and earth," Feng Qian said slowly, he has been stuck at this threshold for decades, and he has never been able to step in.

"What is God?" Argo had heard the term "God" more than once.

"Gods are just mortals who have cultivated to the highest realm of martial arts, and they have a power that ordinary people can't understand" Feng Qian gave the answer, he was telling Ah Ge about the realm of martial arts, and what Ah Ge lacked the most was relevant knowledge.

"In this place where we live, time and space are the most basic and stable two laws, irreversible and changeable, we call it three-dimensional space" Wind migration ah metal is very serious.

"Is there still a one-dimensional space, a two-dimensional space, and a four-dimensional space?" a flash of inspiration flashed through Ago's mind.

"One-dimensional space and two-dimensional space do exist, as for four-dimensional space, we don't know," Feng Qian replied.

"Why isn't there a four-dimensional space?" Feng Qingyu was also the first time she had heard this concept, with her martial arts cultivation, she had not yet reached the point of touching this kind of knowledge, although with the status of the Feng family, she had also heard of the concept of space dimension, but she had only heard of it.

"The one-dimensional space and the two-dimensional space are the source of our strength, and they are extremely unstable, so we martial artists can get power from them, and the three-dimensional space is very stable, so we can live in it, and if there is a four-dimensional space, that level of stability will not be able for humans to live in it" Feng Qian answered the question of Wind Whispering.

"I see," Feng nodded softly, understanding what Feng Qian said.

"There are a lot of substances in the one-dimensional space and the two-dimensional space, elements, vitality, fighting energy, and many substances that we don't know, magicians, warriors, and fighters can communicate this substance, and thus derive their own power" Feng Qian's words, Ah Ge nodded when he heard this, he is a magician and a martial artist, and now he finally has systematic knowledge.

Feng Qian said very carefully, basically he could answer the questions raised by Feng Qingyu, but some of Ago's questions were extremely obscure, and those who couldn't answer them would shake their heads and be silent.

"Does four-dimensional space really not exist?" said Argo, eager to know the answer to the question.

"Theoretically it doesn't exist," Feng Qian couldn't understand why Ah Ge had been entangled in the affairs of the four-dimensional space.

"Theoretically?" said Argo, who had formulated the theory, and Argo questioned his credibility.

"If you keep struggling with this problem, then your martial arts attainments are bound to take a detour" Feng Qian felt that he needed to remind this young man, he didn't want to see such a demon with martial arts talent go astray, not to mention that this was still the person he chose for his favorite granddaughter.

"The third grandfather is not worried, the kid just asks casually" Ah Ge smiled and explained, he could feel the change in Feng Qian's attitude from the bottom of his heart, and after accepting himself, Feng Qian showed full kindness.

Of course, Ah Ge would not be naïve to think that if he was just an ordinary person, he would exchange for the kindness of Feng Qian and the Feng family, there is no love for no reason, and there is no hate for no reason, and Ah Ge has the ability to be interested in the Feng family.

Feng Qian said a lot, and Ah Ge could agree and understand, but about the concept of "four-dimensional space", Ah Ge had his own guess in his heart.

The predecessor of the Dragon Dragon Sword Spirit once said that the first generation of Dragon Warriors led the Dragon Clan to find a hidden space when they were dying, and hid it, calling it the "Fourth Space".

Why is it called the fourth space, not the first space, the second space, or the third space, Argo has also thought about whether there is any meaning of the "fourth", and now Argo feels that the fourth space is likely to be a "four-dimensional space" that no one has discovered.

According to Feng Qian, theoretically, the four-dimensional space is more stable than the three-dimensional space, and it is fundamentally suitable for the existence of three-dimensional space, but the power of the first generation of dragon protectors "Qian" is unprecedented, and it is likely that it has the power to open up the four-dimensional space.

"There are two ways to enter the fourth space, one is to find the space key and pass through the entrance, and the other is to use itself as the key to communicate with the fourth space" This is the clue left by the old man of the Dragon Sword Spirit.

The current Argo doesn't know where the space key is, it's been 10,000 years, and I'm looking aimlessly, I really don't know when I'll be able to find it.

Then the remaining way is to use himself as a secret key to communicate with the fourth space, but Argo guesses that this method is necessary to wait until he becomes a peerless powerhouse to be possible.

But in any case, it gave Argo some impetus to his quest over the years.

The harvest of this trip was huge for Ah Ge, not only because of learning Ling Feng's swordsmanship and martial arts knowledge, but also because he comprehended the wonderful artistic conception of "sword intent", and most importantly, he knew that the fourth space was likely to have a great relationship with the four-dimensional space.

After Feng Qian finished teaching Ah Go's Ling Feng Sword Technique, he had already left before Feng Qingyu and Ah Go, and for him, it was the most important thing to let go of the Feng family's concern and follow the footsteps of the Feng family's ancestors.

No one has the strength to detect the traces of a half-step peerless powerhouse, and the person who has the ability to probe is none other than Count Flatley, the guardian of the free city-state, but Lord Earl obviously won't do this, people like him are all single-mindedly pursuing a higher martial arts realm, unless the free city-state is attacked by a saint like himself, he will make a move.

The long-term population of the Dream City is about 10 million, and countless anecdotes of all sizes happen here every day, which become the jokes of the aristocracy after dinner.

And today there is an earth-shattering news in the free city-state, the first heir of the Feng family, one of the three major families of the free city-state, Feng Qingyu, wants to withdraw the marriage contract of the heir of the Ka family, the upstart family of the free city-state, this matter has become the mainstream of today's free city-state.

But the protagonist of the story is neither the beautiful and unbelievable whisper, nor the talented and famous young Kase, but a boy with no name, and this boy is Ago.
