The Han Li, who had remained motionless for a while, suddenly raised his right hand and straightened a single finger, an action that seemed rather puzzling. However, not long after, at the level where his fingertip rose half an inch, a subtle ripple of spatial disturbance occurred, and a few sparks materialized out of nowhere. As soon as the sparks appeared, they instantly emitted a sharp "crack!" and, within the twisting space, transformed into small, round red fireballs the size of walnuts. Though these fireballs were not large, a wave of intense heat immediately spread throughout the entire room upon their formation. Han Li still lay motionless, his face covered by a book, as if asleep, while the small fireball at the tip of his finger continuously emitted a steady "crack! crack!" sound of high-temperature combustion—standing out vividly against the stillness of his otherwise unmoving hand. Time passed minute by minute, and the fiery sphere still maintained its extraordinary vitality, showing no sign of fading. Yet Han Li finally began to react—he felt the tips of his fingers tremble beneath the flame. At first, only his fingers were affected, but as time went on, his wrist, his entire arm, and eventually his whole body gradually trembled. Suddenly, Han Li shot straight up from his chair, so abruptly that the book resting on his face slipped to the floor without his awareness. His eyes were fixed intently on the small flame at the tip of his fingers, his face flushed with intense effort. Sweat beaded on his skin from forehead to neck, and his entire body felt warm and perspiring, as though he had just completed a vigorous exertion. A moment later, the fire ball began to tremble as Han Li shook violently throughout his body. The flames on its surface fluctuated—sometimes growing larger, sometimes shrinking—unable to maintain their calm. Soon, the flames diminished and the fire ball gradually faded into scattered sparks, vanishing into the air. As soon as the fire ball disappeared, Han Li felt as though his spine had been drawn out, immediately collapsing back into his chair, looking utterly exhausted, as if he had just completed a physically demanding task. "This Fire Ball Technique truly is difficult to master!" Han Li said to himself, gazing upward. "After nearly six months of dedicated study, I still haven't fully grasped its essence—only managed to extend its appearance by a little bit." Indeed, toward the end of the secret manuscript on the Long Spring Technique, several rudimentary spells were recorded—clearly foundational spells for beginners. These had proven invaluable to Han Li, who found himself unable to fall asleep for several consecutive nights, excited and eager to learn them. It's no wonder he's so excited, for since witnessing the several spells demonstrated by Mo Doctor, Han Li has been deeply fascinated by these astonishing, profoundly powerful techniques. Yet, sadly, Han Li now possesses the full strength of the Chongchuan cultivation technique at its peak level, yet he is as helpless as a beggar carrying a golden bowl, utterly unaware of any spellcasting techniques—knowing nothing at all about the fundamental principles of spellcraft. Now, however, he has suddenly discovered several spell incantations perfectly suited for a beginner like himself, which can only leave him overjoyed. The five spell incantations recorded on the final pages are "Fire Ball Technique," "Stabilizing Spirit Seal," "Wind Command Technique," "Object Manipulation Technique," and "Heavenly Eye Technique." To Han Li, each line of these incantations feels ancient, profound, and utterly difficult to comprehend. It's no wonder, for the terms in these incantations are composed using a more ancient grammatical vocabulary. Though he had read many books, his grasp of this particular aspect remained quite shallow, making it difficult for him to immediately comprehend their meanings. In the end, Han Li finally regained the determination he had once shown when learning the Changchun Technique, immersing himself deeply into a stack of ancient literary texts. He studied the true essence of each incantation night and day, meticulously analyzing and pondering every sentence and word repeatedly—often dozens of times—before he would rest, ensuring that no ambiguity remained. Even though he had never previously studied any form of spellcasting, he well understood that such an immensely powerful force, if even slightly misapplied, could be far more disastrous than the phenomenon of true qi going astray and causing internal damage—potentially even claiming his life at once. For his own safety, Han Li thus approached the matter with great caution and never dared to be careless. After three months of in-depth study, Han Li finally fully internalized all the techniques in theory. Thus, he began his actual practice of spellcasting. However, this hands-on training proved to be a significant setback. He had assumed, based on his sharpness in mastering the "Glimpse Sword Technique," that spellcasting would not be particularly difficult. Yet, upon attempting it, he found himself suddenly astonishingly clumsy. Though he fully understood the underlying principles, when putting them into practice, he consistently failed—either his hand movements were incorrect, his incantations were off, or his magical energy was insufficient, making him appear utterly dull and unintelligent. Han Li was completely at a loss. While he could address the issue of insufficient magical energy by simply taking a few more medicinal pills, this particular difficulty stemmed from his own inherent inability. It was thus his own conclusion, after considerable effort, that his natural aptitude for spellcasting was not as strong as he had originally believed. After years of persistent practice, Han Li finally made modest progress in the "Fire Ball Technique" and the "Heavenly Eye Technique," yet he still failed to even reach the threshold of the other three spells, achieving no noticeable effects at all. Frustrated, he concentrated his full mental focus on the two spells he could currently master—the "Fire Ball Technique" and the "Heavenly Eye Technique"—and harbored great hopes in them. The power of the "Fire Ball Technique" truly did not disappoint Han Li; in fact, it far exceeded his expectations. Though the fire balls produced by this technique were not particularly large in volume, the intense internal heat they carried was almost unstoppable, capable of igniting or melting any substance it touched. Even steel blades, when struck by such a fire ball, would have their points of contact instantly melted into molten iron. After witnessing such terrifying, almost inhuman power, Han Li even tossed a fire ball onto the water's surface to test it, and immediately, the entire area ignited like oil, showing no sign of being subdued by the water. Only after fully grasping the power of the "Fire Ball Technique" did Han Li finally understand why Yu Zichong held such an aloof, disdainful attitude toward ordinary people. Consider this: a cultivator with only a basic mastery of magic could easily defeat renowned martial masters in the world's renowned martial circles using a simple technique like the "Fire Ball Technique." If a more accomplished cultivator were to step in, wouldn't they sweep the entire martial world clean, becoming utterly unbeatable? With such a vast disparity in strength, it was no wonder that cultivators like Yu Zichong regarded ordinary people as mere insects.
