How To Craft Medicine In Black Myth: Wukong

screenrant.com:

You can craft different medicines in to temporarily or permanently boost your stats, but you can't start crafting these items until you complete an NPC's side quest. The character Xu Dog you meet in Chapter 2 has the recipes for medicine that he's willing to teach you. With two kinds of powerful medicine in the game, there's a lot to learn.

Medicines are not to be confused with drinks, consumables, or your healing gourd used to recover health during fights. While those items could cure poison in or help you recover from other ailments, medicines provide stat boosts. There are two types of medicines — normal Medicine which gives you temporary stat increases, and Celestial Medicine which makes those improvements permanent.

You'll come across Xu Dog for the first time in Chapter 2 near the Village Entrance Keeper's Shrine in Sandgate Village. From this point, drop from the wooden bridge to your right to the gorge below to find Xu Dog in a cave with foxes painted near its entrance. Talking to the NPC for the first time will start their questline, which is tied to the crafting of basic medicines.

Xu Dog asks you to defeat the frog Lang-Li-Guhh-Baw, a boss who has swallowed his medicinal formulas. This enemy is almost a carbon copy of Baw-Li-Guhh-Lang, a similarly amphibian boss from Chapter 1 from the Bamboo Grove area. Unlike the Whiteclad Noble in or other humanoid bosses, the Lang-Li-Guhh-Baw has a bestial move set that may be easier to predict.

The Lang-Li-Guhh-Baw has the same move set as the Baw-Li-Guhh-Lang, only with some of its attacks being imbued with lightning to deal more damage and create AoE bursts from time to time.

Once you take down Lang-Li-Guhh-Baw, you'll receive the Evil Repelling Medicament formula that Xu Dog was looking for. Return to Xu Dog to unlock the ability to craft regular Medicine at Keeper's
