Black Corporation: Joseon
Chapter 388
At Hyang’s command, Jang Yeong-sil opened the bag he had brought and took out two fist-sized objects.
“What are these?”
Seeing the objects Jang Yeong-sil had produced, Hyang inwardly exclaimed.
‘Archimedes’ screw?’
Meanwhile, Jang Yeong-sil began to explain.
“As you can see, this is a modified version of the drill used for digging wells. Since the way the windmill-type propeller pushes water is similar to how a drill bores into the ground, I thought it might work with a few adjustments, so I made this.”
“That’s true, but…”
‘Is this really something that can be done with just a few adjustments?’
Hiding the doubt creeping into his mind, Hyang nodded.
