The Guai horsealso known as Ma Tianba, is one of the characters you can meet during the first chapter Black Myth: Wukong. This character appears several times throughout the game and interaction with him is optional. However, a mysterious expedition centers around him, which can be deviously easily missed.
This quest requires encountering Horse Guai in almost every chapter Black Myth: Wukongbut it's worth completing for the final reward: the powerful Dark Thunder transformation technique. This guide details every location where you need to talk to Horse Guai Black Myth: Wukongalong with an expanded section detailing the details of the Dark Thunder transformation.
