Gang Reyong's body wasn't the weakest.
With his body-strengthening skill, he already has the strength of a Martial Trainee right at the beginning.
And with Death Energy strengthening him, his body was even stronger than an ordinary Second-stage Martial Artist; however, there was a slight problem, and that problem was that his body has never practised martial arts.
Even the Will he got was handed down to him by the skill.
Sure, it could grant him a Will and allow him to be a Second-stage Martial Artist.
He also had some martial knowledge from the Main Body and Chun Ma, but in the end, there was still a problem:
Muscle Memory!
He didn't have the muscle memory of a veteran Martial Artist.
In actuality, if he really fought in a sheer competition of martial arts, then he might not even be able to beat Martial Trainees.
"But."
He tightened his fist; black haze swirled around his arms.
