While Fujin and Hiruzen kept talking and while Fujin is lazily thinking about Kekkei Genkai there are 134 Orphans just standing there and staring at him lol!
I hope that Fujin is able to learn Senjutsu & use it as a medium to perfect:-
(1) Hiruko's Kekkei-Genkai technique
(2) Body Revival Technique
(3) Zero-Tails
Fujin should also find Ryumaku Vein & create his own version of Ryumaku Chakra Control to have access to almost unlimited Chakra.
