Moreover, there was once a mage who researched the related topic and finally discovered that if a batch of newly born slimes, which had not digested any food, were fed enough pure ores of the same kind, they might even evolve into particularly special species.
For example...
If newborn slimes are fed with iron with a purity as high as 99.95%, under certain conditions, they will naturally evolve into Iron Element Slimes. Even after their death, their bodies become quite useful materials.
Therefore, in a place like Molten Furnace Castle, which is domestic in equipment forging, there exists a vast number of slime cultivation factories.
They directly let the slimes digest single metals and then kill them, so that they can obtain higher-quality materials from the slimes' corpses, which their previous metallurgy technology could not achieve.
It was precisely because of understanding this research that Kael thought to use slimes' power to digest the Magic Prohibition Stone.
