"Within a certain period of time, it can only be used once. So how long is that period?" Chu Feng asked.
"That actually varies from person to person, depending on one's cultivation. Currently, in the Upper Realm of the Great Thousand, the shortest cooldown between Immortal Art uses is half a shichen. The only person who has achieved that is the strongest being in the entire Upper Realm of the Great Thousand — the patriarch of the Chu Heavenly Clan."
"The longest cooldown between Immortal Art uses is one day."
"Of course, that cooldown refers to the interval between uses of the same Immortal Art. Different Immortal Arts can be used consecutively."
"For example, the Immortal Art Heavenly Lion Fist that Chu Xianshuo used — after he launches it at you once, he'd probably need to wait a full day before using it again."
"However, if he has cultivated other Immortal Arts, he could immediately follow up with another Immortal Art right after the Heavenly Lion Fist," the Immortal Armament Villa Master explained.
"I see. This junior understands," Chu Feng said.
"Furthermore, Immortal Arts, just like martial arts, are classified into tiers based on their power."
"Immortal Arts are divided into nine tiers, from weakest to strongest."
"The first tier can be cultivated only by those who have reached at least the Third Grade of True Immortal."
"But normally, one must at least be a True Immortal to cultivate them, so the fact that Chu Xianshuo was already cultivating a first-tier Immortal Art while only at the Fourth Grade of True Immortal is truly astonishing — it proves that he is a martial prodigy."
"As for second-tier Immortal Arts, one needs to be at least at the Sixth Grade of True Immortal to cultivate them. Normally, that requires the Eighth Grade of True Immortal. And so on."
"In short, first-tier through third-tier Immortal Arts can be cultivated within the True Immortal realm."
"But fourth-tier through sixth-tier Immortal Arts can only be cultivated by those in the Celestial Immortal realm."
"As for seventh-tier through ninth-tier Immortal Arts, only Martial Immortal realm cultivators can hope to master them."
The Immortal Armament Villa Master explained all of this to Chu Feng in great detail.
"Then which is stronger — Immortal Arts or Forbidden Immortal Martial Arts?" Chu Feng asked.
"Actually, compared to Immortal Arts, Forbidden Immortal Martial Arts are far rarer. As for which is stronger, Forbidden Immortal Martial Arts themselves also vary in power, making it difficult to give a definitive answer."
"But in my opinion, even the weakest Forbidden Immortal Martial Art surpasses a third-tier Immortal Art."
"As for stronger Forbidden Immortal Martial Arts, there's no fixed conclusion."
"In the history of the Upper Realm of the Great Thousand, there was someone who used a Forbidden Immortal Martial Art to oppose a ninth-tier Immortal Art — and won."
"Of course, this only happened once, and only with that particular person. His own exceptional abilities may have been a factor," the Immortal Armament Villa Master said.
"Senior, may I ask who this person was?" Chu Feng was extremely curious.
Because he had already grasped the implications. While the weakest Forbidden Immortal Martial Art surpassed a third-tier Immortal Art, under normal circumstances, a Forbidden Immortal Martial Art would only be stronger than a third-tier or perhaps fourth-tier Immortal Art — it should be absolutely impossible for it to surpass a ninth-tier Immortal Art.
The gap in tiers between them was simply too vast — an enormous chasm that was nearly impossible to cross.
Yet that person had managed to defeat the strongest of all Immortal Arts — a ninth-tier Immortal Art — using a Forbidden Immortal Martial Art. That alone proved he was someone truly extraordinary.
And on top of that, he was the only person in the entire history of the Upper Realm of the Great Thousand to have ever accomplished such a feat.
Chu Feng felt that this person must have been a legend. Though he didn't yet know who it was, his respect had already grown immensely.
"Heh heh heh…"
However, in response to Chu Feng's question, the Immortal Armament Villa Master did not answer. Instead, he let out a meaningful chuckle.
"Could it be, Villa Master Senior, that there is some reason you cannot speak of?"
"You are unable to tell Chu Feng this person's name?"
Chu Feng asked. He could tell that the Immortal Armament Villa Master did not wish to reveal this person's identity.
"This person's name is indeed a taboo in the current Upper Realm of the Great Thousand. However, there is no one else here, so there is no harm in telling you."
"As it happens, there is a certain connection — this person shares your surname. His name is Chu Xuanyuan," the Immortal Armament Villa Master said.
