This chapter was a bit off for me, first was the Chakra has no subtance thing, does that mean the rasengen isnt physical at all? Second is the Added weight technique which now works as added density instead of adding the effect of gravity. Not only that, apprently added density now turns rock into metal... what?!
Okay, let me answer these... 1. Chakra IS Energy, as that is how it is introduced; it is created by melding Physical Energy and Spiritual Energy. Now, Rasengan on the other hand is a Ninjutsu that takes the Shape Transformation of Chakra to the limits, so much so that it uses the rotational force generated by constantly rotating chakra to do Physical damage. However, that doesn't make Chakra a Physical substance, it's still energy. 2. The added weight technique is indeed adding gravity; by increasing gravity, it increases the density of the solid. Also, the sentence starts with a "like" so it's not actually turning stone to metal, it's like.
