As the sun dipped below the horizon, casting long shadows across the training grounds, Feiyin sat cross-legged on the wooden floor of their home, his breath steady, his heartbeat calm. His body was exhausted from the morning’s physical training, but now, as always, the real lesson began.


    Cai Feng sat across from him, his presence unwavering, the flickering oil lamp casting shifting patterns of light across his sharp features. Tonight’s lesson was different. Feiyin could feel it in the air—the quiet weight of something important.


    “You already understand that the Body Tempering Realm is about strengthening the body so that it can endure Essence Qi,” his father began, his voice steady and deliberate. “But what you must now realize is that the body does not simply sit idle as it grows stronger. It is constantly generating power—whether you control it or not.”


    Feiyin’s eyes flickered with curiosity. “You mean internal strength?”


    Cai Feng nodded. “Yes. Kinetic energy, raw and unrefined, is constantly being produced within you. Every movement, every heartbeat, every breath contributes to it. But without direction, it is nothing more than wasted force.”


    Feiyin thought back to the times he had felt something shifting beneath his skin, a faint pulse of energy that seemed to ripple within him. He had always thought it was his breath, or his blood moving. But now…


    “You’ve already been using internal strength,” his father continued. “You just didn’t realize it. Every time you perform a breathing exercise, every time you stretch your muscles or hold a posture, your body generates a natural force. The breathing techniques you’ve been practicing are designed to guide that force—to direct it into your organs and temper them.”


    He reached over and tapped Feiyin’s chest lightly. “Every part of your body must be prepared to handle energy. The skin, muscles, bones, marrow, and blood all generate kinetic energy to increase strength. But your organs must also be tempered—because they control the very foundation of life.”


    Feiyin sat still, absorbing the information.


    “Each of the five breathing techniques you practice is specifically designed to guide this internal strength into one of your five major organs,” Cai Feng explained. “The Tree Breathing Technique guides internal strength into the liver, purifying the body. The Earth Breathing Technique reinforces the spleen, stabilizing the body’s core balance. The Metal Breathing Technique nourishes lungs, increasing endurance. The Water Breathing Technique enhances the kidneys, improving longevity. And the Fire Breathing Technique fuels the heart, refining circulation and adaptability.”


    Feiyin’s mind raced. He had felt it—the way his body responded differently depending on which breathing technique he used. But now, with this knowledge, it made sense.


    His father’s gaze hardened. “But tempering your organs is a delicate process. Too much internal strength flowing into an organ can damage it instead of strengthening it. That is why I always monitor you—because if you lose control, it could cause internal injuries.”


    Feiyin swallowed, suddenly realizing how dangerous even breathing could be in cultivation.


    His father continued. “For example, if you force too much strength into your heart, your blood will surge too quickly, and you may rupture your own veins. If your lungs receive too much, your breath will become erratic, and you may suffocate without even realizing it.”


    Unauthorized duplication: this tale has been taken without consent. Report sightings.


    Feiyin exhaled slowly, feeling a newfound respect for the balance of training his father had enforced.


    For a moment, there was only silence.


    Then Feiyin hesitated before speaking. “Dad… in the past few weeks, I’ve noticed something during the breathing exercises.”


    Cai Feng’s eyes sharpened. “Go on.”


    Feiyin took a slow breath. “Each breathing technique… vibrates differently. When I practice the Tree Breathing Technique, I can feel a pulsing rhythm deep inside my body, stabilizing and stretching outward. When I use the Fire Breathing Technique, the vibration is faster, almost like a steady drum. Each technique produces a unique pattern.”


    His father remained silent, waiting.


    Feiyin clenched his fists. “And… those vibrations match the oscillations of their respective elements. The Tree Breathing vibrates like the trees in the forest. The Earth Breathing vibrates like the earth. The Metal, Water, and Fire techniques… they all mirror the elements they’re connected to.”


    A heavy silence filled the room.


    Cai Feng’s expression did not change, but Feiyin could see it in his eyes—the flicker of awe, the realization that what he had just said was something far beyond normal comprehension.


    Slowly, Cai Feng let out a deep breath. “Feiyin… do you know what you’ve just told me?”


    Feiyin’s heart pounded. “Is it… something important?”


    Cai Feng exhaled again, shaking his head in quiet wonder. “More than important. It is profound.”


    He studied Feiyin carefully, as though reassessing something he had once believed. “Most cultivators only understand the breathing techniques as methods of strengthening the body. But you… you perceive their essence. You see how they interact with the world itself.”


    Feiyin’s mind whirled. He had always seen oscillations, always noticed how things vibrated differently depending on their nature.


    His father continued. “This ability of yours… if used wisely, it could change everything about your cultivation path.”


    Feiyin hesitated before asking, “Dad… can I experiment with it?”


    Cai Feng’s gaze sharpened. “Explain.”


    Feiyin licked his lips. “I want to see if I can replicate the oscillations of the elements—not just through breathing, but by using internal strength itself. If I can match their vibrations… maybe I can understand how to harness them better.”


    For a long moment, his father said nothing. Then he let out a low chuckle. “You truly take after your mother in curiosity.”


    Feiyin grinned slightly. “Does that mean I can try?”


    Cai Feng’s smirk faded, his expression serious again. “Only under one condition—you do not experiment alone. Either I or your mother must be nearby at all times. If something goes wrong, we must be there to intervene immediately.”


    Feiyin nodded eagerly. “I understand.”


    A flicker of amusement crossed his father’s face. “You don’t understand yet. But you will.”


    The conversation ended there, but in Feiyin’s mind, a fire had ignited.


    His perception of oscillations was not just a passive skill—it was something he could actively explore, refine, and perfect.


    And now, he had his father’s permission to push the boundaries.


    As he lay down to sleep that night, his mind drifted into a familiar space—the endless void of his dreams, where the Eight figures stood, silent and unmoving.


    But tonight, something was different.


    As he focused, he felt it—the faint vibrations of something new. A subtle rhythm, woven between the infinite hum of the world.


    His heartbeat quickened.


    This was only the beginning.
