As the smell of blood came caressing his face, Wu Qi snorted coldly and shot out a ball of pitch-black Nine Nether Ghost Flame, which quickly caught and ignited the blood flag. The flag looked sticky and filthy, as a sea of blood was vaguely visible, rocking violently in it. Countless vengeful souls could be seen bobbing and tumbling in that sea of blood, letting out miserable shrieks and howls. It turned out that such shrieks and howls came with an evil power capable of shaking and pulling one's soul out of the fleshly body, repeatedly attacking Wu Qi's divine soul.
