This strange whistle sound inexplicably made people's hearts tremble. However, now Wang Xiaoqiang, having comprehended the True Meaning of Thunder, developed resistance to it, so it didn't seem as terrifying anymore,
He opened his Heaven-Opening Eye and scanned the place where the sound came from, and as before, he found nothing unusual,
But in that glance, he noticed several Puppets, Black Demon, Dragon Serpent Great Demon, Ge Laoda, and Little Yin flying towards him. Obviously, the Puppets had annihilated the six Evil Kings and were gathering towards their master, him.
Sure enough, when the four Puppets reached him, the Dragon Serpent Great Demon respectfully said, "Master, all six Evil Kings have been executed."
"Hmm, very good." Wang Xiaoqiang nodded, with a thought, collected the four Puppets, and continued to listen to that mysterious sound. The sound intermittently echoed for a while and finally stopped.
