"A teleportation portal?" Lu Bela got up and stood beside Rudy.
"Yes."
"But… you can teleport without any portal, right?"
"Yes. I don't need it for me. I need it for the girls."
"Oh." Lu Bela pondered for a few seconds. "What type of teleportation portal do you have in mind?"
"A kind of portal that can only be accessed one way."
"Now that's difficult."
"What about the device you had that your UnderBlades used when they kidnapped the Ross family? Wasn't it similar to a teleportal device?"
"It is, but using that is not ideal. You want a portal that can only be accessed from one way and it should always be active. The teleportation device I had didn't have such functionality.
Moreover, they require batteries to run, which can only be obtained from that merchant. I wouldn't suggest using them."
"I see…" Rudy took a moment to think and asked, "Have you tried reverse engineering the teleportation device?"
