Wujing is a demonic barbarian who likes to capture and eat humans. 
However, as Sanzang's disciple, he is actually kind-hearted and loyal, and likely the most polite also the most realistic, and always try to protect innocent people at all cost. 
Wujing is sand demon, and general in heaven, he uses himsef as sand to disappear from enemies.
Wujing will dissapear rugs and scams
