The sea of thunder was different from other practice locations. First of all, it was extremely dangerous there. Any carelessness would lead to death.
In addition, the wide sea of thunder had to work with a secret method to take effect. Otherwise, practitioners would only be tortured by thunder and lightning rather than improve.
This secret method was called the Thunder Formula, one of the few methods that worked on thunder and lightning.
Practitioners of this method relied on thunder to work on their carrier of martial arts. They were able to strengthen their protective energy jars, too.
However, practitioners wouldn't be able to control thunder and lightning directly.
Thunder and lightning were the fiercest forces in the world, their destructive power strong.
Jiang Chen had developed all eight of his extraordinary meridians, thanks to which he had been able to master some wonderful methods and summon wind and thunder.
