-Dual-headed Rat/Qingshan Bone
After grabbing the treasure chest, head back down and walk towards the red line.
In this area, you will encounter a Dual-headed Rat.
The Dual-headed Rat is considered elite, tough to defeat, and will explode in a large area when killed, so make sure to get away quickly.
It will drop a Linglong Pill. After defeating the Dual-headed Rat, you can return to the Rat Country Citizens (preferably teleport), where you will find that they have already left, triggering the mission.
Further ahead, you will encounter a combination of Dual-headed Rat, Rat Mage, and Rat Person.
It’s best to lure them over one by one and defeat them, as being ganged up on can be tough to handle.
Continuing forward, you will see a large gate, which will lead to a boss battle when opened.
In the house on the left side with a red circle, there is a Lingyun, which can be absorbed by getting close to the door.
Additionally, in the map of this area provided earlier, there is also Qingshan Bone, a type of wine-soaking item that appears randomly when gathering licorice (increases maximum health for a short time after drinking).
Opening the gate will lead to the boss battle in the Notch Valley.
