2514 The Economic Crisis of the Imperium

Li Yao told Li Jialing that the legal tender of the Imperium of True Human Beings, which had been established at the center of the cosmos for a thousand years, was named "crystal coin" because the currency was dependent on high-purity crystals in the beginning.

At first, there were five hundred million crystals of ultimate quality as the support of the crystal coins of the Imperium. Every dollar of crystal coins could be exchanged for 0.1 grams of ultimate crystals unconditionally.

"Ultimate" was not an exaggerated modifier but had a very strict standard. Only the crystals with a purity of more than 95% could be marked as "ultimate". The only things purer than the ultimate crystals were the rarely-seen marrow crystals.

Such a guarantee empowered the crystal coins with high credit and vitality, helping Blackstar the Great to crumble the vulnerable economic and financial system of the obsolete Star Ocean Republic.
