Chapter 529
Darius began work immediately. He focused on a huge slab of stone he brought to his lab and cleaned it to perfection.
It had much more mass and density than a human did, because while Darius could use the spells Flesh to Stone and Bones to Stone, he hadn't mastered them.
This meant there would be a significant margin of error on his first many tries, so the goal right now was to perfect himself until he achieved what he needed to do.
First, he worked on Flesh to Stone, turning the rock slab's various parts onto living flesh before turning it back into stone. After all, with how most Material element spells worked, there was no need to always replace used material with a new one.
You could just change it back with a little bit of mana to its original state and then re-do whatever you made before. This was actually one thing the Material element had over Transmutation.
Darius worked on this non-stop for 30 days, an entire month!
