I am very interested

Three gray wolves in a pincer formation, pushed aside the clumps of grass, stepped with all four paws, and let out a low growl like a threat, slowly pacing towards Jingyang.,Jingyang disregarded the mental barrier because the other wolf he had just knocked over was already charging back from behind. One claw landed on the back of the wolf Jingyang was controlling, leaving a bloody wound soaking its fur. Jingyang gritted his teeth, this pain was too real!,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。
