Bab 217: Chapter 1: Demon Emperor's Cave Mansion, Deep Hatred in the Sea of Blood [3 in 1 for Monthly Tickets!]_3

If taken outside, it would be a sin to harbor such a treasure, like a child flaunting gold in the marketplace, no different from seeking his own death!

These extremely rare top-grade spirit crystals were piled high on the table, with at least a thousand in his estimation.

A single top-grade spirit crystal was equivalent in value and spiritual energy to a thousand high-grade ones; a single high-grade one was equivalent to a hundred medium-grade ones, and a medium-grade one was equal to a hundred low-grade ones!

Even the lowest grade spirit crystal would cost twenty thousand taels of silver per piece on the market, and was often priceless.
