He totalled everything up. Although the Fort Masters, when counted individually, did not have more crystal coins than Madame Wu Hua, the crystal coins of the seventy-two Fort Masters when added together was also an insane amount.
When all the Gold Crystals, Black Crystals and White Crystals were counted as Gold Crystals, there would be around thirty million coins altogether. Changing them to White Crystals would be three hundred billion coins, while exchanging them into Black Crystals would net him three billion coins.
This had yet to include the total of sixty hundred and twenty thousand Gold Crystals from Madame Wu Hua.
To those high level cultivators with status, these may not seem like much. However to Miao Yi, this was definitely an astronomical number. Even if he were to act as the Cave Master of East Arrival Cave for a lifetime, he would not be able to obtain this amount.
