Sun Wukong and Tai Bai Jin Xing once again left the Murky Water Cave of Kan Yuan Mountain and continued northward until they reached the Palace of the Sea Cover located at the bottom of the North Sea.
The Demon King Jiao was their second oldest sister among the seven kings sworn in brotherhood, and she was the first one to become acquainted with Sun Wukong among them.
Although the two had started off with a fierce fight, as the misunderstandings were cleared away and they became sworn siblings, Sun Wukong gradually discovered that the Demon King Jiao was the most sincere among them.
The Demon King Jiao was not as experienced in worldly ways as the Lion Camel King, nor as cruel or honest as the Peng Demon King. She wasn't as calculating as the King of the Monkeys and the Yu Ruyi King either.
She acted impulsively and rashly, which often got her into trouble, but she also valued loyalty and fellowship.
