The Alchemy God could not hear Alex.
The Alchemy God wasn't alive. At that moment, he was nothing more than a disembodied voice, tied to a memory, kept for the moment when his inheritor would find one of his books.
It was a message from the dead Alchemy God to Alex.
"My successor, if you have found this book, then you must have gone to the Cailan tribe of the Nineskull continent in the Wiseflower Spirit realm. I do not know how you acquired it, but I am happy that you did. No doubt, this was the most difficult to find of all the three."
Alex frowned. 'This is supposed to be the most difficult?' he thought. He still had the other two books to get. At least, he knew where one of them was.
"In the unlikely chance that you have not found the other two yet, I will tell you where they are."
"I have hidden away the Book of Endless Recipes in the Death God's tomb in Celestial's Cradle just a few years ago. If luck is on your side, it is still there."
