The first scroll is for refining phase, but it's not very powerful. It's called sword energy, and it can only be released from hard rocks. The second scroll is about condensing it into flying sword energy. The energy is in the body, but the speed is slow, so maybe he might be able to use it to his advantage. He's excited to think about it. According to the jade, one-third of the body's mana must be mobilized to produce a sword, so he's thinking about how he can use his sword energy to increase his speed. He notices that his elder brother is cultivating a golden yang sword ship, and he wonders if this is a technique of refining phase. The elder brother only uses the mana of his refinement phase to do his sword-fighting, so his power isn't terrifying. He wonders if someone can go and see for himself what's happening.
