Alex kept quiet for a bit, thinking to himself of the things he just learned.
Pearl's mother wasn't in the Beast paradise when she was attacked. She was in the Azure Dragon's realm. That made it more obvious that the Azure Dragon's death was somehow related to Pearl's mother's death as well.
The question now was on which side of the conflict was the Azure Dragon?
Alex could see him being on either side.
He could have been a benevolent master, helping one of his servant during an attack. He could have showed himself to the heavens during that moment and brought on the wrath.
Or, he could be a hateful Heavenly Beast who realized that Pearl's mother had the White Tiger's blood essence in her on the same tier as that of the White Tiger progenitor, and wanted to kill her for that.
