This was the first ghostly immortal that Wu Yu had devoured.

However, before too long, the Butchering God Sect's leader, Xiao Yuntian, was gone with the wind.

Everything about his life was being thoroughly used by Wu Yu. Wu Yu had discarded many of the useless memories, only keeping those pertaining to immortals, ghostly immortals, the world, and cultivation.

To him, these were the essence.

A ghostly immortal was more "nutritionally balanced."

Ghostly immortals did not have the physical essence of demon immortals, but in terms of dao insight and the usage of ghostly immortal energy, they were well-versed.

Wu Yu's Heaven Devouring Avatar was not like his real body. He would absorb any dao, no matter what it was.

Although this was just a 1-Yuan ghostly immortal, it was still of great help to Wu Yu.

His understanding of the Great Ancient Ink Realm had already surpassed many of this world, including his knowledge of the world's history.

He now also knew who the hundred-odd immortals and ghostly immortals in this place were.

Even which immortals and ghostly immortals were stronger, how strong they were, and what they were strong...
