The morning sun was just right. Through the branches and leaves of the old locust tree in the courtyard, dappled light and shadow were cast on the ground. A black-feathered myna in a cage hanging from the treetop let out a crisp call, adding a touch of tranquility to the small courtyard. However, the moment Fang Cheng stood firm, it seemed as if an invisible aura dispersed the tranquility. His feet were shoulder-width apart, knees slightly bent, his back straight. His hands hung naturally by his side, his eyes slightly closed. A simple horse stance, yet he exhibited a demeanor of profound mastery. It seemed as if he wasn’t just standing there, but like a mountain growing from the ground, steady and solid, becoming one with the earth beneath him. The bird calls around the courtyard had ceased at some unknown moment. The elders sitting by the stone table unconsciously held their breaths. Even Ma Jianguo put down his purple clay teapot, staring intently at Fang Cheng with extraordinary concentration. The next second, a sudden change occurred. A deep, resonant sound seemingly originating from deep underground rang unexpectedly in the courtyard. The sound was initially faint, like the muffled thunder heard through thick walls, but it quickly became clear and sonorous. The air trembled, and invisible sound waves rippled through the courtyard like waves. The teacup on the stone table, its lid clinking urgently against the cup body, emitted a slight "click" sound. The leaves of the old locust tree rustled without the slightest breeze. The source of that sound was none other than Fang Cheng standing in the courtyard. His chest and abdomen visibly heaved with a faint yet intense frequency. Every rise and fall was accompanied by a thunderous boom that struck everyone’s ears. The sound grew louder and richer, like rolling spring thunder reverberating between heaven and earth. This was not merely a sound from his lungs, but a resonance from the stirring of inner qi, echoing through his organs and bones, to every inch of his flesh.

It was deep and oppressive, like the low roar of the king of beasts patrolling the mountains, the majestic roar of a fierce tiger descending the hill! Then "crack!" followed by "boom!" A series of rolling thunder-like explosive sounds surged one after another from the spine straight to the back of his head. The sound was filled with a sense of primal and wild power. Like a swift leopard racing across the savannah, the friction of muscles and bones, the throbbing of organs resonated, merging with the booming thunder. "It’s the Tiger and Leopard Thunder Sound!" Ma Jianguo blurted out. He could no longer maintain composure, standing abruptly from the stone stool, his eyes wide open, filled with incredible shock. Professor Wu Dewang’s eyes twinkled, unconsciously pushing his glasses as if to see more clearly. Zhang Haixiang and Chen Zizhen exchanged glances, seeing the same astonishment in each other’s eyes. Even Dong Yunchuan, who had seen Fang Cheng’s extraordinary talents before, had his mouth agape wide enough to fit an egg. He pointed at Fang Cheng, making a hoarse sound in his throat but unable to speak a word. Originally, it was just to let Fang Cheng show off a bit to his old friends, to astound them, but instead, he was once again left speechless with astonishment. What other skills is this kid hiding? However, it wasn’t over yet! As the heart-stirring Thunder Sound reached its peak, wisps of white mist began to steam from Fang Cheng’s Baihui acupoint and the pores of his body. The mist started like smoke, then like clouds, quickly enveloping him completely. Releasing an astonishing heat, it was like boiling water. The temperature in the courtyard seemed to increase by a few degrees as a result. Sunlight penetrated the layer of mist formed by the evaporation of vital essence and sweat, refracting a hazy halo. Making him appear like a celestial being from legend riding the clouds. It was a magnificent spectacle, a divine skill! Finally, when the Thunder Sound and roar reached their peak, Fang Cheng slowly brought his palms together in front of his chest. Then, he let out a long breath of white air. This breath shot out more than two feet before dissipating in the air. In an instant, the wind stopped, and the sound ceased. All anomalies came to an abrupt end. The white mist surrounding his body was reabsorbed, as if it had never existed. The courtyard returned to its previous tranquility, leaving only the heavy breathing of a few old men. Fang Cheng slowly opened his eyes, his gaze clear, breath steady and prolonged. As if the earth-shattering scene just now had nothing to do with him. Fang Cheng finished and stood up, looking at the completely petrified elders before him, he calmly spoke: "My dear mentors, I have embarrassed myself." The entire courtyard plunged into a dead silence. The first to react was Zhang Haixiang, who had just lost at chess. He rushed up with a single stride, ignoring all seniority, hands groping all over Fang Cheng, clicking his tongue in amazement. "Hot, still hot! Kid, ... are you a monster?" Chen Zizhen also gathered around, his eagle eyes fixed sharply on Fang Cheng’s abdomen, as if trying to see through his Dantian. "The secret manual records that the Tiger and Leopard Thunder Sound is a supreme divine skill for training the internal organs and cleansing muscles to transform the marrow. When mastered deeply, the organs become as firm as iron and stone, the bones surpass even dragons and tigers." "But this technique demands too high talent, one slight mistake and it risks damaging the internal organs, leading to madness. For nearly a century, no one has heard of anyone mastering it, yet you’ve really mastered it?"
