Chapter 433: Thunder Pearl

After scouting the location half a day at Thunder Ridge, Ye Zhen finally selected a tree stump with a diameter of one zhang in a corner of the central part of Thunder Ridge as the first spot for his practice of the Thunder Secret Technique of Fright.

This tree stump was charred black by the thunder light, its surface completely carbonized. Roughly every sixty breaths, lightning would strike down from the sky onto the stump, stirring up a whiff of blue smoke.

The frequency of sixty breaths was very stable, perfectly suitable for Ye Zhen, who was just beginning his practice of the Heavenly Thunder of Fright.

Of course, most importantly, after observing for nearly two hours, Ye Zhen noted that within a ten-meter radius of this tree stump, there was no other lightning strike. It wouldn't cause any accidental injuries!

This was crucial for Ye Zhen, as an unintended lightning strike during practice could prove fatal if the consequences were severe.
