Cocooned Cow
...or did Lin Ming managed to get a hold of the purple card in the end? i never get to finish the last 50 chapters so i have no idea but from what i heard on a spoiler, Sheng Mei was sealed inside the Purple Card after the battle with the Abyss Devils. So the black armored spear user is most likely the Asura Road Master, both are spear users after all but it cant also be denied the possibility of Lin Ming.
