Lan truly did as he had promised. He and Xue Wei spent the rest of the day where Xue Wei continuously released one attack after the other, only to be told by Lan how to make the flow of Qi within his meridians change.
Xue Wei learned how to enhance the strength of his attacks further; he learned how to control the accuracy of the attacks better than before and how to control how much energy he wished to use on the attack.
He was learning how to control the flow of Qi within his body perfectly. Previously, he had been using full power every single time he released an attack, but now he could fully control that strength.
"You are learning fast!" Lan praised him with a grin on his face. "Now onto the last thing I am going to teach you today."
"I will teach you how to overdraft your energy," Lan said seriously. Lan’s usual manner of joking and teasing was suddenly gone, replaced by a solemness that made Xue Wei observe him seriously.
