The Silly Version:
What should you do if you transmigrate to the Middle Ages? Asking online, and it's pretty urgent.
Get farming and advance technology, make gunpowder, smelt steel, form a musketeer squad, seize money, grain, and princesses, and climb to the pinnacle of life! Remember to grant the title of Earl of Glamorgan!
What? There really are witches in the Middle Ages?!
For the sake of cute girls! Bring down the Church!
What the heck! The Church's white-robed guys with sticks can really throw fireballs! And they even say sorry!
Let's beat up a noble and start farming to calm down...
Why do knights have powered armor?! And I don't even have saltpeter!
You must have entered nightmare mode. My condolences.
...Actually... I think I'm a great noble myself...
Bring down feudal autocracy!
The Literary Version:
The world is material. Everything within the light cone is fate. Earth is humanity's cradle, yet the laws of physics cruelly confine us to it. Airplanes symbolize our longing for speed, machines represent our pursuit of strength, and computers expand the reach of human intellect. Yet the splendor of modern civilization only throws into sharper relief how fragile and insignificant we are. Imagine a world where thought could influence matter, where humans could fly into the sky through their own power, cross a thousand miles in an instant, and create miracles. How fascinating that would be.
