Day after day, Ian practiced Alchemy during the day, refined Blood Essence at night, and meditated before going to sleep.
He could feel that as his Bloodline Purification Technique neared its limit, his understanding of the model deepened.
The Witchcraft Model in his mind became increasingly clear, each Energy Node and path of circulation seared into his memory like a brand.

For instance, he experimented with changing the pace of his Spiritual Power's penetration and adjusting the compression ratio of the condensing Energy, all in an attempt to find a more efficient and stable refinement method.
Although most attempts ended in failure, the occasional success brought a more substantial increase in his Skill Level.
The threshold for Limit-Breaking was drawing ever closer.
