Ghost Ticket Machine.
So such a thing really existed.
He had lived in this other world for quite some time, yet he had never actually seen how train tickets were produced.
The last time he rode a train in the Yeke Kingdom, Slyther had handed him the ticket directly.
The Ghost Train Ticket Machine before him looked more like an old typewriter dug out from some abandoned corner.
Its body was a heavy army green, its surface and edges worn and battered, with rust covering some of the internal parts.
The typing area was at the bottom, with a neat row of round keys and a long, slender lever on one side.
Wu Heng examined it carefully, and the Ticket Machine's attributes appeared immediately afterward.
Ghost Train Ticket Machine (Curio) Effect: Prints tickets. Side Effect: Sacrifices souls. (Description: An aged Ticket Machine with a special function. If you are willing to offer up your soul, you may begin a special journey.)
As Wu Heng looked at its attributes.
His brows furrowed once more.
The side effect was sacrificing souls... The price was far too steep.
But on second thought.
He immediately realized something was off. The Second Prince could not possibly have sacrificed his own soul. If a soul was damaged, the lighter consequence would be becoming dull-witted and foolish; the severe consequence would be the soul directly collapsing.
The Second Prince's own level was not high, and the strength of his soul was even less likely to withstand the side effects of a curio.
Combined with the Human Bone Nail, the first of the three curios they had seen, everything could be explained.
The Human Bone Nail's effect was to extract Residual Souls.
He must have used that curio to exchange for tickets at the Ticket Machine.
