At the same time, Lu Ye had not forgotten his earlier plan to use the environment here to store fuel for the Talent Tree.
He quietly activated the Talent Tree's power, and roots visible only to him extended from beneath his feet, probing deep underground.
The roots could not extend very far, but since the Underground Fire could be drawn onto the artifact-refining platforms, its location could not be too deep.
Therefore, there was a strong chance that the Talent Tree's roots could reach it directly.
Guiding them with his mind, he had the roots searching underground. They soon found the Underground Fire. The next moment, devouring, drawing power flowed through the roots, swallowing the energy of the Underground Fire.
After the Talent Tree had completed its transformation, Lu Ye could control where the energy it absorbed went. It could either be stored as fuel for the Talent Tree or used to ignite its leaves and unlock new Spirit Patterns.
He had previously obtained seven Spirit Patterns at once and had yet to fully comprehend them, so he had no intention of unlocking any more. Besides, in this place, he had no mind to study new Spirit Patterns. Thus, he stored all the absorbed energy as fuel.
Within the vast Artifact Refining Workshop, he was the only figure present. Lu Ye had removed the Red Dragon Battle Robe, baring his upper body as sweat poured down him before the refining platform. Every blow of the artifact-refining hammer added another pattern within the sword blank. As the patterns continued to increase and interlock, a Spirit Pattern gradually took shape.
Thus, one restriction was formed.
Constructing Spirit Patterns by hammering the sword blank with an artifact-refining hammer was countless times more difficult than constructing them with Spiritual Power. That was why artifact
