"Vivi, what kind of element is this?" I asked, touching the blue head of the sledgehammer.
"Analysing the material..."
"Material analysed!"
"The material is made by mixing the saturated blue flame with cold iron. It can be used to extract Soul stones."
"Vivi, can I use this material to temper the gate's magic circle in Mine Number 10?"
"No, the blue flame inside the hammer head is too saturated to be used as source material."
"Huff, so it can't be done," I sighed, laying back on the stone bed.
"Blue flame... blue flame," I murmured. "Is it the same blue flame I saw in the furnace at the entrance of the metal gate from which I entered?"
"Yes it is!"
"Oh, but if I try to go outside to claim it, I will be burnt to ashes."
"No you won't. When the Host was imprinted by the branding, Vivi removed all the restrictions from the Host's body so you may freely travel through that gate."
