Body Cultivation System

"Rely on me on this one," Jabba said seriously

"Huh?!" Robin raised one eyebrow, "Rely on you for what? You'll make everyone become an expert in Nihari's body cultivation system before the 15-year time limit? You know very well that body-strengthening divine tattoos depend on a person's talent in how to deal with the amount of energy absorbed and how his body deals with the changes, This is something that cannot be accelerated, otherwise, it will backfire and paralyze the body instead."

"I will make everyone experts in the body cultivation system, yes, but not Nihari's!" Jabba explained

"..Explain further." Robin knotted his eyebrows, still not understanding what Jabba was trying to say, Is there even another body cultivation system other than the one the First Heaven's Chosen invented?
