Ace was resting on a tree.
He was still in the outer area of this border forest and didn't encounter any demonic beasts or humans.
But he didn't care, and all of his attention was on rune crafting because he only got a day, so he wasn't planning on wasting even a second of it in traveling.
The Heavenly Rune Crafter Manual was very well structured because every part was arranged in a strict order. Simply put, Ace can't just learn the runic eyes technique and start rune crafting, he has to understand every part before he could craft anything.
Now that he has already mastered a stage of runic eyes. It was time for the Runic Soul Manipulation Technique, also the second part of the manual.
The runic soul manipulation technique has twelve levels, just like the Rune Crafter tiers. The higher level he goes, the higher his rune crafter tier will be.
