In winter, this terrible fish goes fishing in the lake.

The blood pool crazy fish killed an animal near the Druid camp in Taiyuan. You have debuff. Don't meet a druid, or you will die. Find a puddle and jump in. Your debuff disappears and the puddle becomes a blood pool. Just fish here (if you jump into the lake and find a piece of water on it is red, throw the hook into the red water to fish).
