Because of the fierce battle just now and the flying swords, a hole had been blasted through the roof of the Sanqing Great Hall. Just then, a gust of wind blew past outside, and several leaves drifted down through the opening, only to meet the finger force fired by the old man in white and instantly turn to dust.
Although those in the hall could not see the shape or trajectory of his finger force, that instant alone was enough to reveal just how destructive it was.
"One Yang Finger?"
Song Qingshu quickly recognized the martial art his opponent had used. Techniques like One Yang Finger were mainly used to seal acupoints. Their methods were wondrous, and ordinary people could not undo them. At a profound level, one could strike acupoints from afar and injure enemies invisibly; at an even higher level, the finger force specifically broke through an opponent's internal true qi.
It was actually easy to understand. Given the same amount of force, did a palm strike or a finger jab have the larger area of impact? The concept of pressure was taught in middle school physics.
Experts in palm techniques could often send palm force through the air, but when facing a finger-force expert of equal cultivation, they were often at a disadvantage. As long as the finger force punched a tiny hole through the palm wind, no matter how mighty that palm wind was, it would immediately collapse—of course, if they were not clashing true qi from a distance and were instead fighting at close range, this restraining effect would be greatly reduced. After all, two fingers were far more fragile than a palm. Even if one's fingers could pierce an opponent's fleshy palm, the force of that palm would still break them.
