Comments of chapter undefined of Douluo Dalu: The Legend of Heavenly Ruler

It's kinda wierd the dragon graveyard disappeared since the sun and moon empire had access to it for their projects. It was also kinda off that Youlong didn't devour the souls of the 2 head teachers to get their knowledge and skills. It was super important and already showing its downsides. Lost dragon graveyard and time travel info.
