Two pilgrims come to a monastery on their way to Utsang. While there, the monastery is attacked by poisonous snakes, causing all the monks to flee and the monastery to become empty. Then, an old monk tells the two pilgrims that if they can feed the snakes musk, the snakes will die. So, they kill the poisonous snakes as the old monk told them, and they receive a great outpouring of gratitude from the monastery.
