Asura and his reincarnations were basically all hopeless academic slackers; they could not even figure out their own native abilities, so how could they possibly pass on such intricate techniques to others?
As for Indra, needless to say, that fellow was reclusive, arrogant, and conceited. In his daily life, he almost never communicated or interacted with anyone—even a stray dog passing by him on the road was likely to catch a severe beating. How could anyone expect him to have the patience to guide others in their cultivation?
Because of this, although the Nine-Tails' strength was the envy of the other eight Tailed Beasts, it had stagnated and made no real progress for a very long time. Moreover, over the past few centuries, even when the reincarnations of Asura and Indra engaged in earth-shaking, world-shaking epic battles time and again, it had shown a distinct lack of interest, no longer being as enthusiastic about them as it once was.
