Boom! Feng Lin formed his hand into a whip-like seal and lashed down fiercely, like a cosmic ruler perched high on a throne wielding a divine whip, striking those lofty deities down into the dust. Ha! As one move ended, Feng Lin changed his gesture again, his hands coming together like the Seal of Overturning Heaven, slamming down with force, as if the legendary Pillar of Buzhou had collapsed, bringing destruction to the mortal world. Hum! The hand seal shifted once more, fingers spreading wide—one hand representing yang, the other yin; one hand the sun, the other the moon. His hands alternated, evolving into the myriad realms. Roar! His hands rose like mountains, lifted high, and the momentum of the seal transformed again, his presence as steadfast and unshakable as a towering peak... These were the many variations of the Kunlun Great Hand Seal, each move grand and awe-inspiring, shaking the soul. But Feng Lin wasn't practicing martial arts; he was contemplating the power of the hand seals. After reading the basic tutorial for genetic hypnotists, he studied some fundamental hypnotic theories and techniques, mulling them over repeatedly. Among them was a method of hypnosis using hand seals, leveraging intangible momentum to intimidate the mind and forcibly breach the opponent's psychological defenses. And since Feng Lin happened to know a supreme martial art, the Kunlun Great Hand Seal, why wouldn't he put it to use? He had to admit, the results were promising. Once these hand seals were executed, their momentum was impressive, carrying a power that could influence the mind. Often, before the true force landed, they could already intimidate the opponent, causing them to crumble without a fight, making them a viable candidate for a hypnotic technique. But this was, after all, just an ancient martial art. While it could intimidate, achieving genuine hypnotic effects required integrating mental energy techniques and other methods. Feng Lin then searched online for specific hand seal methods—Buddhist Demon-Subduing Seals and Lion Seals, Daoist Heavenly Heart Five Thunder Seals and Rain-Praying Seals, even Christian prayers and various religious rituals—hoping to incorporate them all. Though this was mentally exhausting, mastering the means of mental hypnosis would make it all worthwhile. The more Feng Lin understood the Kunlun Great Hand Seal, the more he realized it held infinite mysteries, too profound to grasp quickly. Its ability to encompass all things was incredibly powerful. This was a technique that evolved and upgraded its grade as the practitioner grew. Its current power wasn't immense, but its potential was limitless. Feng Lin felt fortunate to have obtained this martial art, greatly enriching his repertoire. He used this hand seal as a form of body language, treating it as a hypnotic gesture, experimenting with it over and over. Unfortunately, Feng Lin had no test subjects, so he could only stand before a mirror and practice on himself. Self-hypnosis was no simple feat. Because once a hypnotist employs a hypnotic technique, their mind is focused on it, naturally building defenses, making it hard to fall under the spell themselves. It was like trying to lift oneself off the ground by one's own hand—against common sense and extremely difficult. Only advanced hypnotists could barely manage it. Feng Lin didn't delude himself into thinking he could achieve it overnight. He simply had no other target to practice on, so he used himself. If the hypnotic technique could have even a slight effect on him, it would be far more effective on others. Facing the mirror, Feng Lin took deep breaths, casting aside all distractions, until the sounds around him gradually faded. Silence enveloped him, utterly still. Feng Lin's concentration was razor-sharp, attuned to his own life rhythm—his breathing, heartbeat, pulse, and even the fluctuations of his thoughts, every subtle shift in emotion. Suddenly, he moved, as if grasping a thread of the hypnotic flow. His hands began to sway in sync with his life rhythm, faster and faster. His hands became yin and yang, the hand seal like a Taiji, generating one from nothing, two from one, three from two, and all things from three. As the seals shifted, they mirrored each other symmetrically, like reflections in a mirror, separating the realms of yin and yang. The Yin-Yang Mirror Seal. Feng Lin experimented for a long time, finding this seal to have the most variations. If executed quickly, it could dazzle the eyes and dizzy the mind, making it most effective for hypnosis. Sure enough, as soon as he made this gesture, Feng Lin's eyes involuntarily locked onto the hand seals. He felt his vision blur, his consciousness grow hazy, and he was unconsciously drawn into the rhythm of the seals. He felt time around him slow down, visions swirling chaotically, his sight distorted, and his body swayed like a drunkard, stumbling about. But as this happened, the speed of his hand seals slowed. Feng Lin jolted, snapping awake. Instead of being dismayed, Feng Lin was thrilled. A single success, and it worked so well on himself—it would be even more effective on others. "I actually succeeded! The Kunlun Great Hand Seal is truly wondrous!" His first successful experiment filled him with excitement. But the effect was still too weak; he needed to keep practicing. Feng Lin recalled the sensation, the strange feeling of being cut off from time and space. In Chinese mythology, the Yin-Yang Mirror was the signature treasure of Red Essence, one of the Twelve Golden Immortals of Kunlun, said to connect the yin and yang realms and determine life and death with a single glance. Perhaps this Yin-Yang Hand Seal carried a trace of that legendary divine artifact's essence, capable of inducing illusions of yin-yang reversal. Feng Lin pondered repeatedly, and after gleaning some insights, he experimented again. Facing the mirror, he made one hand yin and the other yang. The styles of the seals were vastly different yet symmetrically mirrored, like two sides of a mirror—one solid, one shadow. Then he switched the seals back and forth, blending truth with falsehood, reality with illusion, making them indistinguishable. In an instant, Feng Lin felt his vision distort, his consciousness plunging into a strange space where yin and yang were reversed, time and space chaotic. But as his mind sank into the illusion, his hands slowed again. "Two successful experiments?" Feng Lin stared blankly at his own hands, finally certain: "Have I become a初级 hypnotist? Tens of thousands, even millions in monthly salary are waving at me." Recalling the strange transformation of falling into the illusion, he grew even more convinced. Self-hypnosis was far harder than hypnotizing others. If it worked so clearly on himself, others would surely be unable to resist. "That hypnotic technique could be called the Yin-Yang Illusion!" Feng Lin thought to himself, filled with anticipation. For now, the Yin-Yang Illusion was just a trick of perception and falsehood, but as his strength grew, could it evolve into a lifelike, reality-like illusion? But to reach that stage, the road was long. He had to stay grounded, taking it step by step. After finishing the tutorial provided by Giant Pharmaceuticals, Feng Lin actively searched the StarNet for materials on mental hypnosis. Works like *Hypnotic Psychology*, *The Multidimensional Structure of Human Consciousness*, *Analysis of Mental Energy Characteristics*... With advanced interstellar technology, humanity's understanding of the body far surpassed that of the ancient Earth era. Psychological academic works were stacked high, countless in number. Feng Lin's vitality was now strong, his mind as fast as lightning, his memory far exceeding before. Saying he had a photographic memory was no exaggeration. He could read ten lines at a glance, instantly memorizing the content and extracting core knowledge points, his reading speed incredibly fast. Unknowingly, an entire day passed. Every psychological work he encountered was fully digested and absorbed, becoming part of his foundation. But humanity was vast, the stars boundless, and knowledge an ocean. A lifetime of study couldn't exhaust it. Feng Lin's intense study over this time had only scratched the surface. Soon, the weekly break passed in cultivation and study, and it was time for work again. After washing up, Feng Lin headed toward the R&D department of Giant Pharmaceuticals.
