Chương 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!

But the spirit crystals were different, they were of great significance to any Martial Artist.

Indeed, Feng Yin had never actually seen a top-grade spirit crystal before, but he had seen medium and high-grade ones, and Zhuang Weiran had mentioned to him the qualities of top-grade ones. These extremely rare top-grade spirit crystals were piled high on the table, with at least a thousand in his estimation.

Feng Yin once again bewailed his own poverty!

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.
