The Portal gate is an ancient technology that was successfully developed by the Grand Wizard into a giant artifact so that it can be a tool that connects one location to another.
It doesn't matter how far the location is, as long as the Grand Wizard has marked the coordinates that will be used as the moving point using the portal gate, long-distance travel in a short time has become commonplace.
But of course, the fuel to maintain the portal gate is very expensive. The large portal gate required a pure mana crystal stone filled with space-type. And the one capable of refining this difficult stone crystal was none other than the Grand Wizard himself.
