How to delete the constellation when encountering an astrolabe?

1. Start with the correct constellation, drag out all the friends in that constellation, and the constellation will disappear, that is, manually throw in a friend, and then click on the constellation page and he will cancel the special pass, and the blank constellation disk will be gone.

2. If you don't need extra constellations, you can drag all your friends out, but constellations can't be deleted, and they can only be arranged in a fixed order.
