The woman asked curiously, "What was the sound you made with your punch just now?"
Lu Ren answered with a rare good mood, "It's the sound of the fist breaking through the air."
"What about the white air on your arm?"
"That's the body temperature rising after intense activity, causing the sweat on the arm to evaporate rapidly due to friction with the air during high-speed punching."
"I see, that requires a strong speed and power to support, right?"
Li Shu seemed a bit disappointed, thinking it wasn't something like Inner Strength or True Qi.
Lu Ren was noncommittal and did not answer the woman's words.
This is not the martial arts those masters shout about online, but true Traditional Martial Arts. Without a strong physique, without superior physical qualities as a backing, no matter how exquisite your Fist Technique skills are, it's just futile labor.
Training fists without cultivating power, it's all empty when you're old.
Hitting others is like scratching an itch.
