Chapter 690: The Crown Prince Who Always Stands on the Shoulders of Giants

"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.
