Xi Yue

Xi Yue (奚悦) is a half-puppet taken as a servant by Xi Ping. He later becomes an instructor for the Kaiming Department and is called Instructor Xi by his students. In Extra 7 - Jinping it is stated that Xi Yue succeeds Pang Jian as Commander of Heaven's Design Pavilion and "kept the peace in the human world for fifty years."

The name "Xi Yue" comes from Xi Ping's biological younger brother who lived to nearly a year old before passing away. Xi Ping treats Xi Yue as a younger brother. The rest of the Xi family at Yongning Marquis Manor consider him a family member as well.

Xi Yue is first introduced as a little boy shorter than the distance to Xi Ping's waist. Both sides of his waist and spine are constructed out of unspecified "special wood" and Moon Plated Gold with rings of arrays placed on them. Parts of his body are visibly wooden, such as his fingers, and as a child Xi Yue was capable of retracting his body into becoming a "square wooden peg." His belly is wrapped in human skin and has a crooked scar. Xi Yue is initially introduced as having "round eyes like grapes," which is a character trait that stays the same even as he grows older, with the Kaiming Department noting that he had "black eyes twice as large as those of other people." His eyes and brows are far apart, which can cause him to look surprised or confused ; although, when he grows older on it is stated that people might interpret his gaze as cold. One of his most prominent features aside from his eyes are his sharp teeth, which are described as "a bed of nails" by Xi Ping.
