Trial of what?

Chapter 493

"I got a few coins."

"I got a pair of daggers."

"I got these strange crystals." Finally, after everyone was done, the man stepped forward and placed shining crystals in Wei Jun's hands. Wei Jun took the crystals, and he immediately knew what they were.

"Wanna sell them to me?" Wei Jun asked.

"What are they?" The man asked.

"Tch." Wei Jun clicked his tongue and replied, "These are pure mana crystals. They don't come out nowadays since the mines containing them dried centuries ago, just like Qi crystals. Just one of these is enough to elevate a first circle mage's mana circle to the second circle. Of course, the amount required would increase, but five of these would be enough for a third circle to jump up to the fourth circle. Seeing you have ten of them, to a mage, their worth is about ten buildings."

The man mused after absorbing Wei Jun's explanation and replied, "Very well, I'll sell them to you. What are you offering?"
