Kindom Building? System? Summning? Waifu's? Sex? R18? World filled with all kind of monsters and men gods and demons.? you do? But do you like harems and cute anime girls? You do as well?! Well then, it's a no brainer then, you should probably read this novel. The way the I integrates different characters from different animes is quite unique, in that they are stages/sequences where the MC goes around. "Want to know the meaning of life? Want to live... a real life?" The world changes when you click YES. In God's dimension, you have to keep getting stronger, keep evolving to survive one horror movie after another. Do you kill everyone in your way to reach the end as a lone king? Or fight along with your comrades and survive through the support of friends? Everything was just for staying alive. Until you find the secret of God's dimension. Who is the real enemy? This way of doing things instead of dumping all of the girls one by one as he is great. Won't be a small summoning list. It's not possible as on every level mc gets a summoning token. And of course with every level he climbed it was harder to climb, the next level required a lot of XP which also meant starting levels would be easier. So more summons to start with… So mc transmigrated into a new world. So it would be an original in a world that's bigger then the sun and filled with god's demons dungeons and dragons monsters and undead and all types of sub species you could say everything fucked every other thing to create new races so all the demi humans and elves. So humans won't be the dominant species.  Mc would start with a rock bottom unlike my other fanfiction. It will be filled with kingdom building, bounding betrayal, death and of course sex a lot of sex.  So what I need is I am stuck on two things. I would have a summoning system so what I want to ask is should I keep a normal summoning system that would summon anyone around the multiverse.   A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions). All the Rights goes to their respective writers
