Capítulo 6127: The art of curses (1)

Xia Yu was different from long Tianlin. Long Tianlin was a person who grew up in the spiritual weapon world. He had never seen crystals or other things that contained energy, so although he was surprised by these pearls, he did not feel anything.

However, Xia Yu was different. Xia Yu was from the sword spirit world, where there were crystals, and crystals were very commonly used. Of course, the commonly used thing here generally referred to low-level crystals. Crystals were also divided into grades, which were generally divided into nine grades. Grade one to three were low-level crystals, grade four to six were middle-level crystals, and grade seven to nine were high-level crystals.
