Cain continued facing The Burning Echoes, learning from every failure in his life and improving his wisdom. With each incarnation born of the fourth layer fading inside his mind, the power of his Ego Wave rose to the next level.
The red light emerging from Cain's eyes was like a radiant burst, with a core ember of fire visible.
The masters of the Sacred Races noticed that dot of fire, and their eyes widened in awe and shock. The transformation of the Ego Wave from a force field into flames was a massive step forward in the evolution of willpower. It meant that your willpower no longer manifested as an energy field but gained a true physical form, allowing you to manipulate matter with your mind.
Most of the warriors of the Sacred Races who had surpassed the 9x9 Ego Destruction Tribulation developed the initial transformation of willpower from energy to physical, but that was after completing the full tribulation, not in the middle of it.
