Shane reluctantly put the magic book of Life Creation Magic back into its place.
Although he was quite interested in this magic, its limitations meant it would never be highly esteemed by Shane.
First, to create a Magic Life, one needed to collect some materials that Shane had never even heard of. Combined with the high variability, it was very likely that he might create something he didn't want at all, which dampened some of his enthusiasm.
Second, Shane wanted to focus on mastering Celestial Magic and Grant Magic, and truly lacked the energy to learn other types of magic.
Thus, after wrestling with his decision for a while, Shane put the magic book of Life Creation Magic back where it belonged.
"If I ever have the chance in the future, I'll come back and learn more about it."
With that resolution, Shane stopped worrying about Magic Life and continued studying his two main areas of magic.
He studied until almost nightfall, when it was almost dark.
