"Mr. Sharp?"
Joseph felt he had heard this name before and so he turned to the extremely nervous young man, "You already have a mature device? That's wonderful."
Sharp hurried forward and bowed respectfully, "It's an honor to meet you, esteemed Crown Prince. Indeed, I have designed a letter transmission device."
Joseph nodded with a smile, "Can you show it to me?"
"Of course, of course."
Sharp hurriedly took out a large roll of blueprints and spread them out on the table:
"Your Highness, look, this is it. I call it 'distant writing'."
Sharp pointed to something on the blueprint that looked like a water tower and explained, "The main body of the device is built on a high tower. Ah, it looks a bit like a huge clothes drying rack, but in reality, it is a rotatable crossbeam with a pendulum arm at each end."
It was only then that Joseph noticed the T-shaped device at the top of the "water tower" that resembled an antenna.
