"Qian Taoist Sect... Elder Yuhua..."
Mo Hua was taken aback for a moment, feeling a bit regretful.
If it had been an elder from another sect, perhaps if fate allowed, he could have visited them one day, established connections, chatted over tea, and incidentally asked for guidance about the formation principles of the Bagua Thunder Formation.
The orthodox Thunder Formation had been passed down through generations within the Zheng Family, and he reckoned he could not learn it.
However, if he were to approach the matter indirectly, seeking knowledge related to the Thunder Formation, he believed he might still gain some valuable insights.
Mo Hua really wanted to know what the Bagua Thunder Formation was like and how it differed from the Thunder Pattern imbued with scarlet Robbery Thunder that he had intercepted from the Heavenly Dao Formation.
If the two shared the same origin and communicated through the same formation principles...
Perhaps he could make an analogy and, by leveraging the principles of the Bagua Thunder Pattern, leap to study the Heavenly Robbery Thunder Pattern in one fell swoop!
The threshold for Qian Taoist Sect was too high, and its elders were likely very proud.
Even if he went to ask, the chances were high that he would be turned away at the door.
Mo Hua temporarily put the Thunder Pattern thoughts to the back of his mind and switched to asking about the 'Secondary Thunder Patterns' that included "electrical patterns" and "magnetic patterns," and the most crucial, the inquiry about Letter Tokens.
"Elder Master Xun, do the formations used in the Letter Tokens include the Magnetism-Type Formations with 'Secondary Thunder Patterns'?"
Elder Master Xun silently looked at Mo Hua, took a moment to consider, and then slowly nodded:
"Ancient Formation Masters studied the Nine Heavens Thunder, manifesting it as Thunder Patterns."
"But the Thunder Pattern is too strong, bearing the might of heaven, brilliant and majestic, and difficult to manipulate, so weaker 'Secondary Thunder Patterns' are derived, weakened, and decomposed from it."
"Secondary Thunder Patterns are generated by electricity inducing magnetism, and magnetism inducing electricity, mutually inducing, attracting and repelling each other, essentially also a special form of Spiritual Power."
"This principle of Spiritual Power, through 'Secondary Thunder Patterns,' constitutes a formation."
"This kind of formation is called 'Thunder Magnetism Formation.'"
"But the term 'Thunder Magnetism' isn't exactly accurate. Because this formation is but a byproduct of heavenly thunder and does not include the genuine 'Thunder'; thus, later Formation Masters generally refer to it as 'Primordial Magnet Formation,' 'Spirit Magnet Formation,' or 'Electromagnetism Formation'..."
Elder Master Xun suddenly sighed, feeling somewhat sentimental:
"With the Taoist Court unifying, the Cultivation World has been at peace for over 20,000 years, and the study of formations has also made significant progress."
"But this development of Formation Study is quite complex."
"Some ancient formations are obscure and profound, and indeed, they have been lost..."
"But there are also some formations, meticulously researched and iteratively improved by generations of cultivators, that have developed far beyond the ancient cultivators..."
Elder Master Xun looked at Mo Hua, "I've told you about the lost ancient formations..."
Mo Hua immediately nodded, "The Chaos Eryi type of formations!"
Elder Master Xun nodded, "Correct, these formations are very deep and obscured, which is why most of them have been lost..."
"The orthodox Thunder Patterns are too dangerous and have lost many inheritances..."
"The other category, which has developed significantly, is the 'Thunder Magnetic Pattern.'"
"Today's cultivators, in their application of 'Thunder Magnetic Pattern,' are not just slightly better but vastly different from ancient cultivators..."
"For example, the Letter Tokens, the underlying formation is built upon 'Secondary Thunder Pattern' and utilizing the principle of 'Thunder Magnetism' to create the Primordial Magnet Formation..."
"But this type of formation is merely a basic Thunder Magnetism Formation."
"Whereas some great sects' Disciple Tokens, such as the Tai Xu Token from my Tai Xu Gate, rely on a complete set of complex and efficient Thunder Magnetism Large Formation, constructed and representing the culmination of Secondary Thunder Patterns..."
Elder Master Xun was about to continue when suddenly, something tugged at his heart, causing him to stop.
Mo Hua's eyes sparkled, half-listening, he couldn't help but say:
"Elder, please continue talking…"
Tai Xu Token, Thunder Magnetism Large Formation...
He had just heard the beginning and hadn't reached the key part yet...
Seeing Mo Hua, Elder Master Xun felt slightly nervous inside, as if continuing would reveal a great secret.
Elder Master Xun's expression turned slightly blank, somewhat in disbelief.
He didn't think he had said much, so how could he have possibly leaked a secret?
To whom did he reveal it?
Surely not, he's just a junior cultivator at Foundation Establishment...
"Elder Master Xun?" Mo Hua uttered in confusion.
Elder Master Xun recovered, coughing slightly, "Let's leave the matter of Tai Xu Token for now; explaining it to you wouldn't be of much use, let me first tell you about the Letter Token..."
Mo Hua felt somewhat unsatisfied, but since Elder Master Xun refused to continue, he couldn't do much about it.
Knowing the principles of formation in the Letter Token was good enough.
"Yes, go ahead," Mo Hua asked with an eager look of seeking knowledge.
Elder Master Xun explained, "From the Artifact Refiner's perspective, the Letter Token is a Spiritual Artifact crafted through integration with formations..."
"But from the Formation Master's perspective, it essentially uses a Spiritual Artifact as formation media, constructing the formation..."
"The essence of the Letter Token is the induction of Thunder Magnetism."
Elder Master Xun continued, feeling the tension of 'leaking Heavenly Secrets' gradually fade, and so he relaxed and proceeded:
"Special in shape, on the surface, it appears as a Jade Slip that can be read by Divine Sense..."
"But within, engraved with 'Primordial Magnet' or 'Spirit Magnet' types of formations, it essentially uses the Thunder Magnetism Formation, Pattern Induction, to perform remote messaging..."
"The range of messaging is limited, the higher the grade of the Letter Token, the further the messaging distance, but generally, it won't exceed the span of a great province..."
Elder Master Xun talked on, while Mo Hua listened attentively.
