Chapter 664, Cultivating the Demon God Transformation

The Wordless Black Book had been inadvertently obtained by Yang Kai, and he had initially been using it as a pillow.

However, after a strange dream and accepting its unyielding will, the Wordless Black Book had opened a whole new world to him.

Yang Kai was able to confirm that the original owner of this Black Book was the Great Demon God from the story Han Fei had told him below the volcano.

She had said that Great Demon God had obtained a massive piece of Soulstone at some point, and although it was unknown what he had used it for, the scraps leftover when he was done had been forged into the four Void Rings that were currently worn by the four Great Commanders of the Ancient Demon Clan.

It seemed like that large block of Soulstone that Great Demon God obtained in the past had been used to create the Wordless Black Book, which meant that the Black Book and the four Void Rings Li Rong and the other Great Commanders had originated from the same source!

In the past, the Great Demon God had wanted to break free of this world’s shackles and explore a higher realm, but the result was his failure and the destruction of his body; however, he had somehow managed to preserve his bones. Because the Unyielding Golden Skeleton originally belonged to the Great Demon God, it was only natural for it to be filled with demonic energy.

The Unyielding Golden Skeleton, Incense Burner, True Yang Secret Art, Myriad Drug Liquid, and Demon Eye of Annihilation were legacies that had been passed down to him by the Great Demon God.

However, Yang Kai’s growth had also deviated somewhat from Great Demon God’s expectations.

When he visited Medicine King’s Valley, Yang Kai had obtained the entire True Alchemic Way, which was not something the Great Demon God had intended him to inherit.

Perhaps Great Demon God wanted his successor to wholeheartedly pursue the Martial Peak and not be disturbed by the Alchemic Way.

Thinking about it, Yang Kai’s eyes lit up and he suddenly remembered something.

Guan’er had once told him that the Ancient Demon Race had produced a top-notch Alchemist, one that all the Alchemy Grandmasters couldn’t stand shoulder to shoulder with.

Had that Supreme Grandmaster Alchemist been the Great Demon God? If not, where would he have obtained the True Alchemic Way?

Although it was just a guess, it was a very
