Owning an Elf Empire From a Tree of Life

What should I do after transmigrating into the royal family of the Night Elf race with countless beautiful Elves surrounding me? Luckily, I possess the Elf Empire System. [New mission received: Guard the base] [Unlock: Tree of Life, Ancient Treant, Moon Well] [Mission completed. Obtained: Elf Swordsman, Elf Magician, Elf Archer, Elf Huntress] As long as I have the resources, I can summon an army of endless Elf babes. Humans? Beasts? Undead? Dwarves? Dragons? Titans? I’m sorry, the world belongs to us, the Night Elves!
