The Champion next to Kyros watched as Kyros wielded power. The Energy Conversion Circle was used to pour in energy that could be used to activate the heat in the cauldron, send freezing energy to cool down an item or infuse elements in it.
The Circle gave energy to several basic cores of Fire, Wind, Ice, Lightning, and Earth. Each Core was a core that the lizards have acquired from various monstrous beasts that could cultivate and has a core.
Kyros was drawing energy from the Earth Core and was absorbing it. He didn't need to but could have just shot a holy bolt attack, but he needed to put on a show and convince everyone that the power he wielded was from the Operating Table and not from his own body.
