He didn't understand, since the world was already at its end, why people still fought and killed each other!,Xu Tian's eyes were bloodshot, he suddenly lowered himself, picked up a stone with both hands, and roared as he charged forward. He frantically smashed the stone against the head of the enemy who had already fallen to the ground!,Accompanied by excruciating pain, a mouthful of blood spurted out like an arrow. Xu Tian soon fainted!。
