The End of the World Is Coming! While Others Are Hoarding Supplies, I Am Amassing Money Like Crazy

(Goldfinger + many beauties + creating a doomsday legion + zombies) Reincarnated back to the day before the end of the world, I will no longer be a licking dog. I can open the space-time store and worry about supplies. Others are trying to survive in the apocalypse, but I am building a survival team in the apocalypse. What's wrong with me being the only man? If I have the supplies, I can handle countless goddesses!
