With the ninth star sphere, the speed at which Jiang Yi merged the two flames increased significantly. He did not even have to pay much attention to the process. All he had to do was use his Fire-Cultivating Dao to transform the flames into energy before absorbing the energy into his dantian. The ninth star sphere took care of everything else.
After six hours, the seven or eight hundred balls of flames in Jiang Yi's Fire Spirit Pearl were all merged together. At the same time, Jiang Yi continued to use his two Chaos Pearls to refine his flames. The ninth star sphere was so big that it seemed boundless. He did not even know how much flame energy it contained. These flames were Jiang Yi's strongest weapon. Of course, he wanted to store up as much as he could.
