With a hoarse roar, a sharp glint flashed once more in Mu Chen's dim eyes. His ethereal form suddenly darkened, turning into a puff of smoke and dust before dissipating completely.
However, under Mu Chen's final act of control, the pitch-black Dantian Vortex abruptly accelerated. This acceleration was so sudden that the thirty-six spheres of light, caught by the pull of inertia, slammed violently into one another. Then, in the last glimpse Mu Chen had before he vanished, the final manually controllable fusion was completed. To his immense relief, Xiao Ying'er's Dantian fragments were completely different from his own; after the spheres of light collided, they required no further manipulation at all, melting and merging on contact.
