I am very interested

Suddenly, the wolf's movements stopped, and Jing Yang was so scared that he didn't dare to move.,The wild wolf that had been munching on its food moments ago suddenly stopped, turned back, and licked its sharp teeth as if it were sneering at Jingyang.,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。
