so let me get this straight because you see and hear the name
"Sage Of Sixth Paths" you automatically assume those are the only techniques? you have to be pretty arrogant to have such knowledge
every pain had one tech and then god pain had shinra tensei ontop of gravtional pull and chibaku tensei
now you cant say you have seen or heard the
Sage Of Sixth Paths mention or use any jutsu or unknown jutsu
cause no one has?
we've only seen his bottom face for gods sake
yes you may be on point with one thing
his
TRADEMARK jutsu are the 6 paths indeed probably the most defined techs of him
hence the name six paths
but again ive mentioned this before
madara taught obito and obito taught nagato everything to know about the sages power
but madara isn't an idiot he obviously didn't teach him everything why would he
he even mentions it in this chapter "don't put me on the same level as someone who took years to extract the bijuu"
again my point madara didn't teach obito everything just enough to do his dirty work.
even now the gedo maze is using chains to extract and we have seen already that when the akatsuki would extract JINCHURIKI not BJIUU it would be the 9 Dragon seal or something those dragons
the rinnengan are madara's original eyes he knows every UCHIHA kinjutsu and Sage Of Six Paths jutsu
don't limit the potential of the original ninja with just six jutsu or paths because of the name
the sage of six paths must have had many techniques to his rinnengan abilities this
RINBO GENGOKU is one of them possibly and more to come TBH
this isn't an ass pull jutsu it is one that just hasn't been revealed
and to point out another thing you said he isn't just using his own chakra reserves he is using the chakra he stole from hashirama sage mode power and he already previously had hashirama power before he extracted the sage part
and he was standing on one of the ninja Naruto had nine tails power on and his foot was extracting kurama chakra from that ninja
due to hashiramas massive chakra and power + Madaras power and chakra and madara able to gain chakra from whatever or whoever he decides to extract or touches he isn't using
'LIMITED CHARKA" he is using the massive chakra he has already build up
and yeah he did knock all the bijuu on there asses what do think it wouldn't hurt them?
he is the second person and only person to activate rinnengan
and knows all techs about it
the sage took on the ten tails alone and split him up to 9 bijuu
not putting madara and sage on the same level but madara is the only one right now closer to him
so it isn't unexpected for something like that to happen
so if your mad about the ass pulls and all this other jazz just don't read the manga haha simple but
you will read it still
you will cause your just on a rant right now probably
