Thunder crystals were one of the nine top-tier elemental crystals. Their status was even higher than that of cloud crystals. They were the specialty crystals of the elemental outer realms, a type of super crystal that could naturally seal elements!
If such an item were placed in the technologically advanced federation universe, it would be an excellent alchemy and forging material!
This was especially true for the production of battle armors, which could stimulate energy activity. Thunder scale armors with extremely high explosive power could be said to be extremely popular on the market. Normally, only the high-level legions under the banner of a great Lord would have the opportunity to load ten tons of thunder crystals, an army that could equip up to ten thousand people would definitely have a combat strength that was against the rules in a plane that was filled with thunder crystals!
