Horse Guai Quest Walkthrough In Black Myth: Wukong

Horse Guai, also known as Ma Tianba, is one of the characters that you can encounter during the first chapter of Black Myth: Wukong. This character appears multiple times throughout the game, and interacting with him is not mandatory. However, he has an enigmatic quest centered around him that’s deviously easy to miss.

The quest requires meeting Horse Guai in almost every chapter of Black Myth: Wukong, but it’s well worth completing for the final reward: the powerful Dark Thunder transformation technique. This guide details every location you must speak with Horse Guai in Black Myth: Wukong, along with an expanded section detailing the ins and outs of the Dark Thunder transformation.

You must exhaust all the dialogue options for the Horse Guai before proceeding to the next chapter. This is because this is one of the game’s missable quests, and if failed, you will have to retry it in their NG+ playthrough.

Black Myth: Wukong— What Is Tenacity?

Tenacity can be a useful ability if Black Myth: Wukong can harness it properly.

Chapter 1 (Bamboo Grove): Talk to Horse Guai Near Back Hills

After defeating Lingxuzi, you will reach the Back Hills Keeper’s Shrine. From this Shrine, head down the stairs, and when you see an enemy Yaoguai, head left into the cave. Inside, you will meet Ma Tianba for the first time.

Chapter 2 (Sandgate Village): Talk to Horse Guai Near Village Entrance

From the Village Entrance Keeper’s Shrine, head through the gates ahead and turn left toward the small structure. You will find the Horse Guai tied to one of the pillars. Exhaust his dialogues before proceeding to the next step.

Chapter 3 (New Thunderclap Temple): Talk to Horse Guai Near Mahavira Temple

Chapter 3 is packed with boss fights, so it’s easy to see how you might miss this Horse Guai encounter. Inside the New Thunderclap Temple, you will need to reach the Mahavira Hall Keeper’s Shrine. From the Shrine, turn around and go down the stairs. When you approach the building straight ahead, turn right and go down the steps to another building. Head inside the building, ignoring the blindfolded enemies, and climb the stairs to the second floor. Turn left to find the Horse Guai standing next to a hanging bell.

Chapter 4 (Webbed Hollow): Talk to Horse Guai Near Bonevault

From the Bonevault Keeper’s Shrine, head left and follow the path right to drop down into the boss arena for Centipede Guai. After the boss fight, head left of the arena and follow the path left until you spot a giant cocoon. Hit the cocoon a couple of times to trigger a cutscene. This will reveal Horse Guai, who was trapped inside the cocoon, and you can talk to him after the cutscene finishes.

Make sure to exhaust his dialogue here before proceeding through the rest of the area.
