What can you do with two hundred years...?
In two hundred years, you can complete an entire Industrial Revolution; transform a feudal dynasty into a socialist nation; or grow a country’s population from three hundred million to 1.4 billion.
You can build a superpower from nothing, one that grows amid blood and tears; drive a bird population of over five billion to extinction; or watch the native population of a vast continent dwindle from flourishing abundance until it vanishes without a trace.
You can awaken a thousand-year-old dragon from its slumber to roar across the world, or watch a long-soaring bald eagle grow weary and edge toward dusk.
You can unite the Demon Realm and modernize it completely, or leave a retired demon so bored that mold grows on him.
You can even fill a late-arriving golden finger shop with the belongings of your group chat friends.
And so begins the story of a demon teacher’s everyday life.
