Gu Heye was ordered by his master to go down the mountain to search for medicine, and picked up an injured wolf cub at the foot of Ailao Mountain. So he took the ferocious and pitiful little wolf cub all over the country in search of medicine. He was carefully guarded along the way, for fear that the little wolf would be injured.
He never thought that one night when the little wolf grew up, he would awkwardly give him a bag of tips and say "I will protect you", and he would be held down and say "from now on, I will be the sword to protect you".
