The so-called "Energy Stones" were a specialized energy source used to charge mecha augmentations.
And the "Neural Link Component" was a bridge connecting the mind and machinery, the crucial step that transformed augmentations from manual control to thought-based operation.
Both of these mechanical components were hundreds or thousands of times more valuable than gold or jewelry of the same volume. They were the kind of treasures that money alone could not buy.
"From this perspective... physical offensive power in this world will develop to terrifying heights because of mechas... but their understanding of the Spirit World and spiritual bodies is still far behind... If I start from that angle and create something like a 'Ghost Mecha,' it would be an absolute slaughtering machine..."
