After passing on the fragment of the "Nine-Days True Scripture" to Dumbelldore, the "Eager to Teach System" officially came into play.
The subsequent task was to urge the disciple to practice his skills. This didn't require any effort from Lin Bai.
Dumbelldore, having finally learned an advanced Cultivation Technique, put in more effort than anyone. For nearly twelve hours a day, he practiced his Inner Strength. The remaining time, besides going offline to recover his energy, he spent cutting veggies in the kitchen to clear his head. Otherwise, if he practiced Inner Strength as soon as he got online, he might go mad.
Other Players, apart from Inner Strength, would simultaneously practice stick, sword, or saber techniques, and even go out to fight monsters for experience. But Lin Bai stubbornly refused to teach him Skills, leaving Dumbelldore with nothing but Inner Strength and no monster-bashing abilities, thus giving him absolutely no gaming experience.
