"How long is the interval during which an Immortal Martial Art can only be used once?" Chu Feng asked.
"It actually depends on the person, on their cultivation level. Right now, in the Great Chiliocosm Upper Realm, the shortest cooldown for an Immortal Martial Art is half a shichen, and the only person capable of that is the strongest individual in the Great Chiliocosm Upper Realm — the Clan Master of the Chu Heavenly Clan."
"The longest cooldown for an Immortal Martial Art is only one day."
"Of course, this cooldown applies between uses of the same Immortal Martial Art. Different Immortal Martial Arts can be used consecutively."
"For example, the Immortal Martial Art that Chu Xianshuo used — the Celestial Lion Fist. After he launched it at you, he would need to wait a full day before he could use it again."
"However, if he had cultivated other Immortal Martial Arts as well, then he could use those immediately after firing off the Celestial Lion Fist." The Weaponry Master explained.
"I see. I understand now," Chu Feng said.
"Furthermore, Immortal Martial Arts, just like martial techniques, are ranked in tiers based on their power."
"Immortal Martial Arts are divided into nine tiers, from weakest to strongest."
"A first-tier Immortal Martial Art requires at least the Third Rank of True Immortal to cultivate."
"However, most people need at least the Fifth Rank of True Immortal to do so. That's why everyone was amazed that Chu Xianshuo had already cultivated a first-tier Immortal Martial Art at the Fourth Rank of True Immortal — it proves he is a martial cultivation genius."
"As for second-tier Immortal Martial Arts, you need at least the Sixth Rank of True Immortal. Normally, you need the Eighth Rank of True Immortal. And so on."
"In short, first-tier through third-tier Immortal Martial Arts can be cultivated within the True Immortal realm."
"But second-tier through sixth-tier Immortal Martial Arts can only be cultivated by martial cultivators who have reached the Heavenly Immortal realm."
"As for seventh-tier through ninth-tier Immortal Martial Arts, you must be a Martial Immortal to cultivate them."
The Weaponry Master explained all of this to Chu Feng in great detail.
"Then between an Immortal Martial Art and an Immortal Forbidden Martial Technique, which is stronger?" Chu Feng asked.
"Actually, compared to Immortal Martial Arts, Immortal Forbidden Martial Techniques are far rarer. As for which is stronger, Immortal Forbidden Martial Techniques themselves also vary in power, making it difficult to give a definitive answer."
"But in my view, even the weakest Immortal Forbidden Martial Technique is stronger than a third-tier Immortal Martial Art."
"As for more powerful Immortal Forbidden Martial Techniques, there's no clear conclusion."
"In the history of the Great Chiliocosm Upper Realm, someone once used an Immortal Forbidden Martial Technique to go up against a ninth-tier Immortal Martial Art — and won."
"Of course, this only happened once, and only in that one person's case. It's possible that his personal abilities played a role as well," the Weaponry Master said.
"Senior, may I ask who this person was?" Chu Feng asked with great curiosity.
He had already grasped the implications. Even though the weakest Immortal Forbidden Martial Technique was stronger than a third-tier Immortal Martial Art, under normal circumstances, an Immortal Forbidden Martial Technique would only surpass the third, fourth, or fifth tier — never the ninth tier.
The gap in ranks between those levels was simply too vast, a chasm that was extremely difficult to bridge.
And yet that person had managed to use an Immortal Forbidden Martial Technique to defeat the strongest Immortal Martial Art — the ninth tier. That alone proved just how extraordinary he was.
What's more, he was the only person in the entire history of the Great Chiliocosm Upper Realm who had ever accomplished such a feat.
Chu Feng felt that this person was definitely someone of great stature. Even though he didn't know who he was yet, he already held the man in the highest regard.
"Heh heh heh…"
However, to Chu Feng's question, the Weaponry Master did not answer. Instead, he let out a meaningful chuckle.
"Could it be that this person's name is taboo, and you cannot tell me, Senior?" Chu Feng asked, realizing that the Weaponry Master did not wish to reveal the name.
"This person's name is indeed a sensitive subject in the current Great Chiliocosm Upper Realm. However, there is no one else here, so telling you shouldn't matter."
