Fuming with anger, Gu Yue’s two soul rings lit up. She clasped her hands together in front of her chest—and a fireball blazed into existence before her. Green ribbons of light swirled around it and merged together as Gu Yue’s hands moved in circles.
Fire and wind were complementary; her wind fed the fire until it turned into a giant flaming tornado.
This firestorm was only one meter in height, but as elementalists themselves, the Zhou sisters could sense the surrounding wind and fire elements converging into the tornado. It quickly grew and a few seconds later, its height already exceeded two meters.
“She comprehends the element’s heart!” The always smiling Zhou Tian’er finally lost her composure as she cried out in alarm.
This element’s heart was only significant to elemental-type soul masters. If they wanted to gain true power, then they had to understand the heart of the element they controlled.
