"Take it."
Raven took the Demon Core from the wooden box and tossed it into Weston's hands. He activated the Eye of Truth and observed it for a while, then replaced it with another Demon Core. He repeated the process over and over.
Weston sat in the chair, staring blankly at everything happening before him. His mind was a complete fog, but since Raven had not said anything, he did not dare move an inch.
This step was actually meant to measure his Elemental Affinity.
Long before experimenting on domestic pigs, Raven had discovered that the energy within a Demon Core would naturally draw close to him. It was the same regardless of the energy's attribute.
This had also been verified during meditation. Raven could absorb the glowing clusters of Earth, Water, Fire, and Wind without any obstruction, and neither Darkness nor Light rejected him.
Earth, Water, Fire, Wind, along with Light and Darkness, were the six fundamental elements that made up this world.
All other elements were derived from these foundations.
For example, Nature Element was composed of Earth and Water; Steel Element was composed of Earth and Fire; and Bloody Element was composed of Water and Darkness...
Being compatible with all six basic elements meant that Raven himself possessed affinity with every element.
Thus, during his experiments on domestic pigs, Raven had begun paying attention to whether their Elemental Affinity could be judged by the level of activity in the energy within the Demon Core.
The method was much the same as today. He placed the Demon Core on the domestic pig and used the Eye of Truth to observe whether the energy inside reacted, and how strongly.
The higher the affinity, the more the energy would surge toward the domestic pig.
Through this process, Raven gradually discovered
