St. Elmo's Fire continued to burn fiercely, refining Su Yu's Silver Core. The Silver Core gradually melted, transforming into a pool of silver liquid, which then evaporated, forming a mist.
Once, when he had refined his Silver Soul, it evolved from a mist state to a liquid state and finally into the solid form of the Silver Core. Now, in the presence of St. Elmo's Fire, the process was reversing. Su Yu sat cross-legged within the diameter of a five-hundred-meter sphere of Golden Thunder and Lightning energy, utterly absorbed in the Soul Core, unconsciously entering the State of Selflessness, oblivious to the passage of time and the pain of his body being continuously struck by the Lightning Power.
