In The Mountain
Even with the continuous loud thud from outside, Albert comes to the library today, mainly to teach me materialmancing again. This time, it's about how to create things that require two materials or more. The prerequisite of doing that is having two containers very close together, and that's it.
"This is very useful, especially if you want to make armor-piercing bullets," Albert says.
"Armor piercing?" Like AP bullets? It's easy to create, to be honest, just put a steel core encased in copper and you'll have an armor-piercing bullet. However, with materialmancing, I haven't found a way to do so.
"Yes, do you really expect a regular bullet to penetrate a soldier wearing thick steel armor?" He asks me back.
