The system allows me to enter and exit various maps, I am invincible

A useless menial disciple awakened the world map system, and gained the ability to enter and exit various maps in the fantasy world. He originally just wanted to improve his strength through the maps in the system, but his luck with women increased dramatically. The daughter of the city lord, the young ladies of the family, the saintly maiden of the sect, the witch, and the fairy all took a fancy to him. He had no choice but to collect heroines in various maps, fight for the universe, reach the pinnacle, and quest to be above the gods.
