Renji rushed back to his room, shutting the door behind him with determination. He quickly removed his shoes, leapt onto the bed, and sat eagerly. "Grandpa Kaiya, come out now. Help me test my magical aptitude." Renji's excitement was palpable. During dinner, his mind was preoccupied with this moment. A soft, radiant light emerged from the Celestial Dragon Ring, coalescing into Kaiya Tanaka. With a smile, Kaiya Tanaka addressed him, "Renji, calm down. I need to inform you that, without specialized magical aptitude testing equipment, I can only assess your potential for earth-style magic. I can't determine your aptitude for other types of magic without the proper tools."
Renji felt a twinge of disappointment. He had hoped that, given Grandpa Kaiya's Saint-level Grand Magus status, there might be alternative methods available. "Only earth-style magic?" Renji questioned. Kaiya Tanaka, brimming with pride, responded, "What's wrong with earth style? Among the elements—earth, fire, water, wind, thunder, light, and darkness—earth is the most powerful." His confidence was evident. Renji found it hard to believe that earth magic could be superior to others. "I've heard that fire-style attacks are the most powerful and darkness-style is the most unpredictable. How could earth-style be the mightiest?"
Kaiya Tanaka's demeanor shifted to irritation as he explained, "Each elemental style has its strengths. For instance, the fire-style forbidden spell 'Celestial Flames Devouring the Earth' can incinerate an entire city, while the water-style spell 'Permafrost Annihilation' can freeze countless people. Thunder-style's 'Supreme Thunder of Oblivion' unleashes devastating lightning bolts, and wind-style's 'Desolation Gale' can create razor-sharp gusts…"
Renji was awestruck. He had thought fire-style was the most formidable, but it seemed every elemental style had its own overwhelming destructive spells. "What about earth-style?" Renji asked, still curious. Kaiya Tanaka's face lit up with confidence. "The earth-style is far from weak. The forbidden spell 'Heaven's Starfall' summons massive boulders to obliterate a city, while 'Divine Skies Crumble, Earth Trembles' causes the ground to churn violently, leading to widespread destruction."
Renji was captivated by the sheer power described. "Additionally, earth-style magic includes the expansive protective spell 'Rhythmic Protector,' which shields an entire city from attacks. It can even block something as powerful as the 'Supreme Thunder of Oblivion.'" Kaiya Tanaka's enthusiasm was clear. "But I'm only discussing wide-area destruction magic, not one-on-one battle spells."
Renji nodded, realizing that Grandpa Kaiya was focusing on large-scale magic. "Why does earth-style seem to have so many forbidden spells?" he inquired. Kaiya Tanaka replied, "Each elemental style is balanced but performs differently based on the environment. For example, water-style magic thrives in aquatic settings, and wind-style is more potent in windy areas." Renji began to grasp the concept.
Kaiya Tanaka continued, "Most battles and magi occur on land, making earth-style magic highly effective. Earth-style magi benefit greatly from standing on the earth, feeling its pulse and energy." His reverence for the earth was evident. "Earth-style also offers significant physical benefits, enhancing the magus's body through its connection with the earth."
Kaiya Tanaka elaborated on the earth-style's defensive capabilities. "The earth-style's personal protection spells include the 'Guardian of the Realm' and 'Terraguard.' At the highest levels, 'Terraguard' becomes a diamond-like armor, providing unmatched defense." Renji was impressed, recognizing the strength of such protection. He recalled the Saint-level combatants he had seen, realizing that the diamond-like armor was likely a manifestation of the 'Terraguard' spell.
Kaiya Tanaka concluded, "This is why I claim that earth-style magic is the most powerful. It's essential to remember that living and fighting on the earth naturally gives earth-style magi an advantage."
