A fabricated identity created by Xie Lanyi for Tang Qingluo's master. Described as a legendary figure from twenty years ago in the Great Zhou Dynasty, known as the number-one mechanism master under heaven. The late emperor personally paid three visits to invite him but was refused. The late emperor left an imperial edict that anyone who finds Xue Liuzhi could inherit the throne. In reality, this person may or may not have existed; Xie Lanyi created this identity to satisfy the family's curiosity about Tang Qingluo's mysterious master.
