There were many kinds of crystals.
Snow crystal, fire crystal, earth crystal, water crystal, and so on.
This kind of crystal contained a huge amount of natural energy, just like a small magic power storehouse, so its strength was far beyond that of an ordinary magic director. It could bear the magic teleportation site, such as this kind of advanced magic.

Tom felt a little regretful. He thought that if he gave each of his important followers a snow crystal that could be transmitted in time, many things would be very convenient.
Tom looked at Riley again. He looked depressed all the way.
As a leader, Tom cared about his follower very much. He asked, "What's wrong, Riley? Are you unhappy?"
