Secrets of the Martial Masters Chapter 141

The sound of Fahai's wooden fish is driven by his magic power and attacks Bai Suzhen's spirit at a specific frequency.

Others can't hear it.

In other words, Fahai was using the sound of the wooden fish to specifically attack Bai Suzhen, which can be understood as a practitioner's means of "precision strike."

This method may seem incredible, but it is actually easy to understand.

There are many sounds in nature that ordinary humans cannot hear, but practitioners with advanced cultivation can hear them. This creates the basis for the "precision strike" of magic power.
