Yun Wan (pseudonym: Lin Wei/A Ruo) was adopted by the declining noble Yun Hou Mansion. He served sincerely but was exploited, framed, and eventually pushed into a cold pool to "drown". Fortunately, he was rescued by an expert from outside the world. After lying dormant for many years, he changed his appearance (disguise/transformation of temperament) and returned for revenge.
