"Mu Yue, looks like I'll be troubling you again today."
Seeing Mu Yue approaching with Asuma, Hiruzen Sarutobi removed his pipe and said with a chuckle.
At first, Mu Yue had merely been a tutor he hired with money. Later, due to various reasons, Mu Yue had been unable to maintain a steady teaching schedule, and Mu Yue and Asuma's relationship had instead become more like that of master and disciple.
"How could a teacher guiding a student count as trouble?" Mu Yue replied with a warm smile.
"Lord Third Hokage, do you happen to have some free time today? I've run into some difficult-to-understand problems in my Earth Release training and would like to ask for your guidance."
"Let's do it now." Hiruzen Sarutobi nodded in agreement.
To keep his son from giving him a filial beating, and because Mu Yue's questions would likely be quite difficult, Hiruzen Sarutobi did not bring Asuma along.
Among all the Chakra Nature Transformations Mu Yue had mastered, earth was one of his weaker ones. This time, he did not ask about things he had already mastered, but genuinely asked about problems he had encountered in training.
At that moment, Hiruzen Sarutobi displayed the knowledge expected of a Ninjutsu instructor. Not only did he quickly answer Mu Yue's questions, he also personally demonstrated solutions and directions for further progress.
"Mu Yue, how is your Flying Thunder God Technique training going? If it hasn't been going smoothly, I can help you choose another Ninjutsu." Hiruzen Sarutobi suddenly remembered and asked.
Half a year had already passed since he had awarded the Flying Thunder God Technique to Mu Yue. If Mu Yue had been unable to learn it after half a year, then he probably never would.
Hiruzen Sarutobi did not think much of it.
