青鱼在太乙山右下角。 You can only catch herring by yourself. Fishing requires fishing rods and cabbage worms. Cabbage worms can be purchased at Chang'an Grocery Store, and cabbage worms can also be purchased in ponds. Save 100,000 silver and go to Quanzhen to buy an exquisite fishing rod, and then spend time fishing. There is a success rate for fishing, but it is relatively low.
