I am very interested

The wild wolf lifted its hind leg and scratched its neck, then continued to bite down. Jing Yang suppressed his breathing and moved back again… Then, he heard the sound he didn't want to hear most: rustling in the grass beside him. Soon, two wild wolves with blood dripping from their mouths emerged from either side, their green eyes fixed on Jing Yang.,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。
