章 5049: Transformation (2)

As for the other type of crystal, it was much weaker. It was the one that was only the size of a finger. It was the small crystal used in the giant Demon Sword. Zhao Hai had many of these crystals in his interspace.

The reason why Zhao Hai had saved so many traction crystals was because he was afraid that he would need them one day. He would keep them when he was free and use them when he was busy. This had always been Zhao Hai's principle, so he had prepared a lot of traction crystals.

Zhao Hai gave it a try and found out that the crystal could be used as a power source for a large-scale teleportation array that could accommodate hundreds of people. This way, the biggest problem of the teleportation arrays in the various cities being restored would be solved. Once the power problem was solved, the teleportation arrays in the various cities could be restored quickly.
