The portal the old man used before to come here was silver in colour, the type that would work on limited distances.
The portal they arrived at was dark gold in colour, much bigger than the one the old man used. "An intercontinental portal level… Where are you taking me?!!" The old man's face changed when he recognised the grade and use of this portal.
"To the central department of course, where else?" the middle-aged man started to take lots of spirit stars. A single one of these was worth a thousand of spirit gems, worth a billion spirit crystals. He didn't just take one or two, he took batches of them out of his ring, like they were trash and common things to find.
The old man was knowledgeable about how these grand portals worked. So, he didn't speak and watched the middle-aged fellow scatter the spirit stars around, enough to fuel the activation of this portal.
