Rewinding time to about 2 months prior, right after Mira defeated the young man, but was stopped due to the interference of an old man.
The old man, the young man's master, looked at his disciple with complicated eyes. Truthfully, he was a bit hesitant to save him back there. Their Sect is not like the Orthodox Sects like the Battle Maiden Sect.
Comradery? Sense of duty? Responsibilities toward the Sect?
None of those things exist there. There are only two kinds of people in their Sect: the strong and the weak.
The weak are merely there as either fodder for the strong or to find a potential strong person.
Their Master-Disciple relationship is more contractual than anything. The old man is nearing the end of his lifespan and is grooming his successor, but the truth is the old man couldn't give two shits whether he has a successor or not.
