What is the eight-character rescue? Can you elaborate on it?

The eight characters that appear out of thin air are generally stars that bring their own good luck, and some also bring their own expensive stars. This kind of person will automatically resolve things or meet with the help of nobles. In other words, this person usually has room to do things, and he can naturally turn bad luck into good luck by making good relationships. On the other hand, a vicious person cannot survive.
