Ideally, extracting gold and silver should take over a week to process both ores. Even with gravity manipulation, Rino found himself at a dead end. He read the tutorial several times but found out that he did not have the materials required to extract gold properly.
Gold was more problematic than silver that could be extracted easily by crushing, heating, and cupelling over grounded bone ash.
Rino worked on the silver and within fourteen hours, the first silver baby bar was ready. Naturally, Rino wasn't inhumane enough to require the bone ash of his subordinates or hunt animals for them. He simply plucked his ribs and ground them into the necessary material. Thankfully, nobody saw him break his own bones for the sake of smelting silver. The subordinates he worked more closely with would have offered their bones instead.
