Talk about ignorance and bias. You two simply want things to go your way, but a reality check, you aren't the authors. ""Hmm, the third databook states (as literal as possible) "At the journey's end by borrowing Yonbi's power, (Roshi) mastered the earth and fire natures fusing Yoton Ninjutsu." or (not so literal) "At the the end of the journey, Roshi mastered the Yoton Ninjutsu, which fuses fire and erath natures, by borrowing Yonbi's power.""

It says clearly that Roshi mastered earth and fire natures and could fuse them into yoton by borrowing Son Goku's power Where did you Ulti and Foxie see Naruto training for Doton or Katon and fusing anything? All I saw was Son Goku handling Naruto the chakra, end of story.
