@kr my problem with it is there was never any for shadowing that you could pass on your martial arts knowledge that way, because my question would be if it can be pass on that way, why the fu** didn't the other nine skies do that to there kids or grandkids, why didn't dam dad pass on everything he knew to dam, why didn't jin dad pass on everything he knew to him, why didn't the night leader just pass on everything he knew to blackwing or that other kid that jin killed back in the second Arc, the one that everyone keep praising in the silent night, he was genius and all this other sh**, he sounded like the perfect person for the night leader pass everything onto, and yet it feel like that way of passing on martial arts knowledge, didn't exist until only a few chapters ago, and that is my problem, because it feels like it came out of nowhere.
