You wake up to find yourself about to be reincarnated into an isekai

You find yourself before a Goddess. The goddess sends you to another world and gives you a mission on Other World. The deity provides you with knowledge and basic necessities for that world and gives you the opportunity to choose one ability to help you complete your mission. Available mission: -) Resolve Overpopulated Monster Problem -) Resolve Declining Population Problem (Inspired by the anime Jobless Reincarnation and Sekai Saikou no Ansatsusha) =====NOTE===== I probably adding more abilities and more missions. Please comment if you have any interesting ideas.
