How does an ordinary baby become a constellation baby?

You can use the horoscope skill book to extract the image of an ordinary baby and get the horoscope baby's.

Enter the game hall, click Baby Paradise, and then click I want to refine. Then click I want to refine the baby image and buy the corresponding constellation baby skill book. It's just that babies who refine constellations need to evolve, and some babies have very high requirements for evolution.

Hope to be satisfied and adopted.
