Ghost Mother.
Ghost Mother, having been suppressed by the Queen Mother, rebelled against the Heavenly Court over four hundred years ago.
Afterward, she established the Ghost Country on earth, which over the centuries has amassed an army of one hundred thousand ghost soldiers.
At this time, the Heavenly Great Saint arrived near the Ghost Country.
On the way, he encountered a lost child.
Sun Wukong saw the child alone and went forward to ask:
"Little one, where are your parents?"
Red Boy sobbed, "M-my home is ahead, but I don't know the way..."
"Amitabha Buddha, Wukong, carry him on your back."
Tang Seng spoke at this moment.
Tang Seng appeared rather stout, a traditionally rotund monk, not as refined as one might imagine.
"Alright."
Sun Wukong carried Red Boy on his back, and the group continued their journey.
After walking no more than two miles, Sun Wukong felt something off.
The child on his back grew heavier and heavier, as though he was carrying a mountain.
