Lin Mu kept his eyes trained on the black smoke and unsheathed the short sword from his back. He had seen the black smoke before and had a guess of what it was. The last time he had seen black smoke such as this was when it rose from Dongfeng Zhao's dead body.
Lin Mu's guess turned out to be true as the black smoke accumulated into a black mass that then turned into a figure that had bone spurs coming out of its body and had skulls present on it.
"Invader!" Lin Mu muttered and entered an attack stance.
Lin Mu did not know if this black figure of the invader was dangerous or not. The last time it had just disappeared and had not attacked him, but that could have only been because it was much weaker than this one.
