บท 5151: The teleportation array (2)

It was important to know that any teleportation array required an energy source. Just like a car, if you wanted to make it run, you must refuel. The teleportation array also needed an energy source. With an energy source, the teleportation array could be used.

However, this energy source was not so easy to obtain. Like in the secret realm, the energy source of the general teleportation array was the bone bead. Every time the teleportation array was used, it would use at least one bone bead. If there were too many people and things being teleported, then the number of bone beads used would be even more.

In the spirit weapon world, the energy source of the teleportation arrays in most places was spirit crystals. These spirit crystals were actually similar to the crystals that Zhao Hai had seen outside. They were also considered consumables. However, there weren't many spirit crystals in the spirit weapon world, so the teleportation arrays used by each city-state were very few.
