"Sounded like mystical gibberish," Erica echoed.


    Debra strode to a nearby patch of grass, picked up a stone, and began drawing symbols on the ground.


    She exined, "Three solid lines represent Heaven, and three broken lines represent Earth."


    Immediately, two opposing symbols appeared on the ground.


    She continued to draw. "This solid line is the positive pole, and this broken line is the negative pole."


    "Is this a trigram?" Randy asked.


    "Thunder rises like a bowl. Mountain inverts are like a cup. Theke is broken above, and the wind is broken below," Debra said as she drew the remaining trigrams.


    Marion quickly figured it out. "That''s our true heiress of the Frazier family."


    The Frazier family was known for their schrly wisdom and military strategy. A century ago, they were legendary figures.


    Debra looked at the trigrams and said, "When was little, I had to learn everything I wasn''t an expert in ancient texts, but I had a basic understanding of them. The


    vel


    trigrams are difficult to understand, but I vaguely remember my father exining them to me. He had a room filled with maps of mountain ranges."


    Randy clicked his tongue. "No wonder! I remember my dad alwaysparing me


    to you. Turns out you were a prodigy."


    "Not really," Debra replied. "It''s just that my family had many books, and my grandfather''s generation had even more. But after I moved to Ralph''s house, my studies fell behind."


    Erica interjected, "You got your master''s degree at 17, and you''re saying your studies fell behind?"


    Liza was stunned. "What? Can people get that at 17?"


    "Back to the trigrams," Debra said. "They are divided into two types: the Early Heaven and the Later Heaven The former corresponded to heaven, earth, thunder, wind, water, fire, mountain, andke. Thetter detailed them into 64 hexagrams extended into the cycles of the seasons. However, the two types are fundamentally different."


    "What''s the difference?" Erica asked.


    "The Early Heaven observes the rise and fall of all things from a macro perspective; like viewing Earth from the universe. The Later Heaven, on the other hand, is about viewing Earth from Earth," Debra exined. "The Later Heaven is often used for predicting destiny. The terrain here feels familiar, as if I''ve seen it somewhere before."


    Liza and Randy exchanged looks. "We don''t get it. Not at all."
