Wu Gang silently nodded. It seemed there wasn't anything wrong with that statement.
"Inner Strength has its roots deep in antiquity, existing since the ancient times."
"And the circulation of Inner Strength also speaks of the seventy-two Minor Circuits of Energy and the thirty-six Major Circuits of Energy, you should know this, right?" Zhou Fuyuan said.
"I don't know!" Wu Gang firmly shook his head.
"It's the number of times that energy in the Dantian circulates through the body!"
Zhou Fuyuan patiently explained, "People have made a specific division for the strength of Inner Strength."
"It's like in a game, isn't it necessary to level up by defeating monsters to earn experience points?"
"The same principle applies, just as a game relies on leveling up and defeating monsters to earn experience points for advancement, Inner Strength also needs to circulate throughout the body continuously to enhance strength!"
