Chương 599: Chapter 599 Exchange Reward_1

The third wish, Ling Xiao did not choose to continue evolving his martial arts, but chose to transform the Evil Beast Demon King into a Martial Soul.

Because the cultivation level of the Evil Beast Demon King was so profound, Ling Xiao had always been unable to transform it on his own. After all, this guy had recovered to the Yin-Yang Realm's cultivation level, which was even more terrifying than the Ancient Hell Dragon in the Moon Blossom Pagoda.

After the Evil Beast Demon King was transformed into a Martial Soul, its strength merged into the Nine Demon God Technique, and Ling Xiao could distinctly feel his Nine Demon God Technique advancing.

"Nine Demonic Divine Arts, Yin-Yang Demon King!"

Jade-grade Entry-level Martial Arts!

The Plague Demon King controlled devastating plagues;

The Evil Beast Demon King controlled various beasts;

The Yin-Yang Demon King, however, controlled Yin spirits and evil creatures.

It's really uncertain what other changes might occur in the future.
