Capítulo 116: Important Training 

"Tough, huh?" Benson smiled, knowing that it wouldn't be so easy for Vicente to move the metal atoms of this mineral with his skill.

Blacksmiths had complex methods for extracting metals from minerals. But it was so complicated that, given the tribulation of the extraction, half of the item's production time was spent on this process alone.

Benson had expected that Vicente would find it difficult to perform this task, which seemed simple on the surface. After all, there was a big difference between manipulating a 'uniform' and dense metallic mass where there were billions of atoms.

In the Polaris Realm, there was no clear and simple concept of atoms as there was on Earth. But the people of this world, especially the blacksmiths and alchemists, understood that substances were composed of small parts similar to atoms.
