On the way to the Disciplinary Courtyard, He Xiaoyao asked, "Brother Yu's cultivation must be quite profound. You must be one of the standouts in the Public Academy."
Yu Zhifeng said modestly, "I am just an ordinary disciple among the multitude in the Public Academy. I have reached Three-Star, but I can't break through to Four-Star. I still need to improve and work hard. Does Doctor He practice any Cultivation Formula?"
He Xiaoyao did not hide it, saying, "I have only practiced some basics to strengthen my body and practice medicine. I need to use some True Qi."
