Family Golden Finger Starts with Recruiting Slimes as Family Members

Under normal circumstances, don't I, as the protagonist, travel through time alone? Shouldn't I be the only one with the ability to cheat? Why are so many people traveling through time this time? There is more than one person with a golden finger. In this case, who is the protagonist? Am I not an NPC character? No way? No way? Forget it, humans are all bastards that can't be trusted, bastards. It's better to recruit monsters to be your family members so that you can rest assured.
