Elder Master Xun slightly nodded his head, "Indeed, but the so-called ’Original Magnet,’ unlike the normal ’Thunder Pattern’..." "The Letter Token involves a type of Formation Pattern that is not ’thunder’ but rather ’electricity,’ or more precisely, ’magnetic’..." "Electric Patterns, or Magnetic Patterns, also fall under the category of the Eight Trigrams Zhen Series, but they are collectively referred to as ’Secondary Thunder Patterns.’ This means they derive from the Eight Trigrams, possess the nature of thunder, but are weaker in power, secondary to the true thunder, and are Secondary Formation Patterns of Thunder Patterns..." Mo Hua suddenly understood. Secondary Thunder Patterns, Secondary Formation Patterns are also considered a type of Formation Pattern Variations. Similar to variations based on the Four Symbols Monster Pattern and Four Symbols Beast Pattern. Elder Master Xun said, "Secondary Thunder Patterns, when electricity transforms and produces magnetism, are similar to some Formation Method in the Golden Series that possess magnetic properties and functions of Si Nan, suitable for reconnaissance, induction, guidance, and messaging." "They are a type of confidential Formation Pattern." Mo Hua nodded, then couldn’t help but ask, "What about the real Thunder Pattern?" Elder Master Xun’s gaze became sharp, and his expression solemn: "The real Thunder Pattern is too complex and too powerful; such Formation Methods are extremely difficult to control…" "It embodies not only the ’Zhen Hexagram’ but also incorporates numerous changes of the ’Qian Hexagram,’ ’Kan Hexagram,’ and ’Xun Hexagram’..." "Hence, it is hard to comprehend, hard to control, and hard to layout." "The real Thunder Formation is terrifyingly powerful and erases all things." "That is the true thunder from the heavens..." Elder Master Xun sighed, his eyes filled with reverence, "The Nine Heavens Thunder symbolizes the majestic heavenly might, annihilating evil and demons, penetrating heaven and earth, and is an evolution of the ’killing’ path." "Although the ’Thunder Pattern’ numbers among the Eight Trigrams, it encompasses a multitude of Hexagram principles and is completely different from other Eight Trigrams methods." "To wield the Thunder Pattern, one’s Taoist Heart must be upright." "Any slight evil or selfish thoughts, and one is prone to be backfired by the heavenly thunder, suffering ’divine punishment,’ perishing under one’s own Thunder Formation." "Therefore, the inheritance of the Thunder Formation is extremely strict." "In this world, the Noble Clans that truly possess the inheritance of the Thunder Pattern are few and far between." Mo Hua was shocked; he thought of the Thunder Pattern he left on the Taoist Stele, which erased everything, deep in thought. But he also noticed another piece of information in Elder Master Xun’s words: "A few and far between..." Mo Hua’s eyes shifted, "Meaning... there are still Noble Clans that inherit the Thunder Pattern?" Elder Master Xun nodded, "There are, but these Noble Clans have mostly been struck by lightning, so they either abandoned their inheritance for development or secluded themselves, not involving themselves with the mundane world, adhering to their own hearts." "The only one that has passed down the Thunder Pattern from generation to generation, with not a small power, is the Zheng Family from Zhen State." "The Zheng Family?" Mo Hua was startled, "Zheng Fang’s Clan?" Zheng Fang... Mo Hua remembered, among his fellow disciples, there was a straight-faced, somewhat honest, occasionally dazed disciple named Zheng Xuan. The first time Elder Master Xun let him substitute teach, Zheng Fang had "tested" him using his family’s secret Formation Method and allowed him to secretly learn a Formation Method. Could that Formation Method have been the Thunder Formation? Elder Master Xun seemed to guess Mo Hua’s thoughts and slightly shook his head, "The Thunder Formation is not lightly passed on, even the legitimate lineage descendants of the Zheng Family the same..." "Zheng Fang is still young and doesn’t qualify to learn the inheritance of the Thunder Pattern; what he learned is at most some basic variations of the Secondary Thunder Formation..." "Not just Zheng Fang, in the entire Qian Xue State Boundary, among the Zheng Family disciples who have joined various Sects, none are qualified to learn the Thunder Formation." Mo Hua felt a bit regretful. But upon reflection, it made sense. The Thunder Pattern was significant, and Zheng Fang, no matter how ’dumb,’ wouldn’t use such a Formation to ’test’ him… Unless he had been afflicted by Planting Devil in Taoist Heart, losing his senses. Speaking of Planting Devil in Taoist Heart, he wouldn’t know how to... "In Qian Xue State Boundary, is there no one who knows the Thunder Formation?" Mo Hua curiously asked again. "There are," Elder Master Xun said. Mo Hua was stunned. "In Qian Xue State Boundary, the only one with the inheritance of the ’Thunder Formation’..." Elder Master Xun furrowed his brows, paused to recall for a moment, then slowly said, "Should be... Zheng Wanjun..." "Zheng Wanjun?" Mo Hua was puzzled. He had never heard this name before. Elder Master Xun slightly nodded, "He is one of the Elder Yuhua from the Four Great Sects, Qian Taoist Sect..."
