As soon as the chief heard the singing, he came out and shot the bow and arrow right into his son's heart without knowing who it was. The wise man had made it look like the chief killed his own son but really he was already dead.
I have killed my favorite son! From now on, I will allow singing in this village.
Just like that, the wise man brought death to an adulterer, restored faith in a faithless wife, persuaded a thief to be honest, caused a cruel chief to repent, and fill a sonless village with songs of villagers.
