The black fire ball that Lin Qiao threw out was small, but the yak seemed to have sensed it clearly. It slightly raised its head toward the fireball, then opened its mouth abruptly and let out a stream of dark mist. A rotten odor was sensed from the dark mist along with a sour, awful smell.
The dark mist from the yak clashed against Lin Qiao's black fire and instantly generated a sizzling noise, sounding like a glass of water being poured on a piece of glowing-red iron.
Boom! In the next second, Lin Qiao raised an arm. Following her movement, the small fireball suddenly expanded into a huge, blazing fireball that devoured the dark mist. Watching its dark mist being devoured completely, the yak moved its strong forelimbs slightly and stomped against the ground anxiously and gave a thunderous roar.
"Roar!"
The roar quaked the earth and even vibrated the ears of Lin Qiao and her friends.
