The Great Northern Emperor had existed ever since the era of the ancient Heavenly City. As such, he naturally had some knowledge on the matters of the ancient Heavenly City's Divine Beast Department, especially considering that he clearly had a good relationship with Slow-Witted Song.
Song Shuhang listened with a smile, and said, "So that's the case. No wonder I've been getting the feeling that Sage Monarch Melon Eater's appearance was really similar to my illusory core's."
"My appearance is similar to your illusory core? Fellow Daoist Tyrannical Song, are you saying that I'm as round as a ball?" Sage Monarch Melon Eater said with dissatisfaction.
An illusory core was the framework for a golden core, so all illusory cores were illusory spheres. With that said, could Fellow Daoist Tyrannical Song be saying that he was fat?
Although he was a whale and his volume was quite large... he was only a little plump, and definitely not fat!
