To upgrade the gourd in Black Myth: Wukong, players must first locate the Shen Monkey NPC, found in the Marsh of White Mist area within Bamboo Valley. This process begins by reaching the Keeper’s Shrine in the marsh and rescuing the Shen Monkey from a nearby enemy, ensuring that you’ll have access to the necessary upgrades.

Once you’ve secured the Shen Monkey’s help, the next step is to gather specific resources: Luojia Fragrant Vines, which will increase the number of sips your gourd can hold, and Awaken Wine Worms, which will enhance its healing capabilities. After collecting these items, return to the Shen Monkey and interact with him to access the upgrade menu for your gourd and brews, effectively boosting your in-game resources and abilities.
