This has nothing to do with the manor level. Go to City 101 to pick up the mission, and pick up the mission at the camp bulletin board of the Chamber of Commerce. After accepting the mission, you will be asked to go to the Autumn Forest to find Brother Haolan. Then talk to Brother Haolan, and he will give you a wooden fishing rod and 10 metal baits, 5 meat baits and 5 plain baits, allowing you to fish happily.

If you still don’t understand, the next good game will be released soon. There are many people playing Tomorrow here, so go to the forum there to communicate.
