Jingyang yanked on the throat of the wild wolf beneath his feet, jerking his head back with a splash of blood. He turned to fight the wolf that had ambushed him from behind.,Soon, the wild wolf stopped struggling. Jing Yang felt a strange aura again, drilling into his heart, both cold and hot. His heart twitched violently. Just as he had struggled to stand up, he fell back onto his buttocks.,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。
