After hearing this, the cultivators who were already accustomed to following orders quickly formed a defensive formation with their familiar comrades, similar to their usual drills, and chased after the nearest war beast by identifying its location through sound.
However, the demon cultivator in charge of the formation within Spring Sun Valley certainly wouldn't let them pass so easily.
With a surge of power like water ripples, the sounds within the formation suddenly disappeared as if they had vanished. No matter how much noise was made, no sound could be heard.
This immediately threw those cultivators who relied on sound for orientation into a panic, while the demon cultivators inside Spring Sun Valley seized the opportunity to focus their attacks on certain areas where the Heavenly Spirit Legion cultivators were positioned.
In just a few dozen breaths, several hundred Heavenly Spirit Legion cultivators had fallen and perished within this formation!
