Attitude Gu
Attitude Gu is an Immortal Gu introduced through The Legends of Ren Zu, where it is captured alongside belief Gu and suspicion Gu. Its central effect is to alter the attitude a person presents, allowing a convincing outward identity without directly changing the underlying self. (Chapters 59 and 87)
Deception and custody
Hei Lou Lan possesses Attitude Gu before Fang Yuan gains its use under disputed terms. Combined with familiar face, it supports disguises that can pass social scrutiny and deceive observers, making it especially effective in infiltration and negotiation. (Chapters 1025, 1132, and 1333)
The Gu does not make every lie true or erase the need for context. A disguise still depends on the user's preparation and on what observers expect, while The Legends of Ren Zu warns that wearing an attitude can deceive the wearer as well as other people. (Chapter 2184)
