章 718: The crystal mine (1)

Originally, Zhao Hai had only come to these mountains to find trouble. Since he had nothing to do, he might as well come to these mountains to take a look. It would be good to collect some things. But now, it was different. After he found the red crystal, he immediately thought that this crystal was a good thing. It was an energy source.

There were crystals on the continent, and Zhao Hai had brought them into the realm before. However, the realm's assessment was that they were low-level products and consumables. There was no introduction to them, which made Zhao Hai very disappointed.

However, this red crystal was different. After it was used, it could be recharged. Most importantly, the energy in this crystal was very powerful. What did 100000 degrees of electricity mean? Zhao Hai had never calculated it, but he was sure that it could do a lot of things.
