Gu Te is the brother to the famous Pill King Gu He. Gu Te has the habit of collecting anything he deems valuable. He also has the tendency to use sacred treasures for such things as foot baths and back scratches.
He is quite arrogant and thinks that all treasure should belong to him and no one else. Even saying things such as "mortals" don't deserve to be in the presence of anything valuable.
He is not afraid nor unwilling to say his brother's name in order to get out of trouble or to simply gain some reputation. However his brother seems less than willing to allow this.
