Gu Xianglin

Gu Xianglin was the adopted son of Cool Breeze Faction's Master. After Gu Ruoyun introduced the Longevity Pill she tricked him into taking the formulas publicly because it would take the heat off her back.

He immediately told his Master about the formulas and that he was going to give them to him but Gu Ming got him to give them instead to the person helped him 'kill' Gu Tian and Dongfang Yu-er.

When people from Cool Breeze Faction came to get the formulas he told them he gave them to someone else so wouldn't let him come back to Cool Breeze Faction which led to him being in the Gu Family when Dongfang Shaoze murdered everyone.
