"What did you say?"
Theresa Locke's grandfather suddenly stood up, his face filled with shock as he looked towards Greg Jensen.
Dark Strength is the first threshold for all martial artists, but this threshold is very easy to cross, as long as one is willing to put in the effort, more than seventy percent of martial artists can enter the Dark Strength Period.
However, reaching the Master Realm is a different story. Eighty, even ninety percent of martial artists spend their whole lives unable to enter the Master Realm.
Out of ten thousand ordinary martial artists, maybe seven or eight thousand can enter Dark Strength, but among these seven or eight thousand Dark Energy Martial Artists, only a few can enter the Master Realm.
It was for this reason that Theresa Locke's grandfather was instantly stunned upon hearing Greg Jensen's words, but after a moment, he felt it was impossible.
