The Insect God's Revelation of World Conquest

I'm the Source of Knowledge, a System. As a qualified world-ending System, with the ultimate goal of spreading terror and despair, I chose super~powerful System resources and super~powerful world-ending items, determined to crush my older sister and all the other veterans in this apocalyptic game.
