Daniel led Patriarch Kim and Kim Yuna to the rearmost cabin of the train. As the door opened, they were greeted by a vast space spanning the entire cabin, filled with strange, futuristic-looking machines that seemed straight out of a science fiction film.
Daniel had removed all the usual amenities from the cabin, leaving only the essentials for this operation, including a portal-like gate at the far end. The addition of numerous artifacts and machines made the space feel somewhat cramped.
"What is that thing?" Patriarch Kim asked, pointing at the portal-like structure.
"It's a teleportation gate," Daniel explained with a confident smile, introducing his latest invention. "This is a portable model that can be installed on large vehicles."
"A teleportation gate!? Are you serious?" the Patriarch asked incredulously.
