Male, revered by the world as Medicine Immortal, one of the four top experts among humans in the past millennium. He is Tong Shuang's master and appeared young but is old enough to be Yu Sui Sui's great-grandfather. Nine years ago he suffered severe injuries that dropped his cultivation from the eighth to the seventh level, forcing him to move to Ling Jun's territory to recuperate. His spiritual power approaches the Fifth Realm. He heard Tong Shuang's secret voice transmission to Yu Sui Sui and thought it fortunate they left the Tian Zhao Sect.
