Jingyang suddenly felt a chill run down his spine, and goosebumps erupted on his scalp. A wave of cold air shot straight up to his brain from the base of his spine.,Jingyang's heart was filled with despair. He quietly let go of the tall grass he had parted, and lay helpless on the ground, hoping that the beast on the slope hadn't actually seen him...,Was it congenital heart disease Jingyang's face was pale, or... He clutched his chest and looked at the wolf corpse across from him, which was no longer moving after being torn apart. Was that strange breath that pierced into his heart because of this wolf's death。
