Eternal tower old players return, 55-level wet nurse, how to play?

If upgraded, wet nurse will always be a hot job. You can upgrade at the temple first, or upgrade to a copy of the forest or mansion at level 57, and then go to Lantusi at level 59. After 60, there is no good way. Either find a big belt, or upgrade the task, or join a guild to upgrade with someone else's trumpet, killing people and playing tricks, and upgrading quickly.
