Douluo Continent: Martial Soul Thunder Dragon, A Century of Glory

(First of all, this is a comic book adaptation, so some things differ from the original text. If you don't understand something, please check out Mu Da's comics.)
The law of the jungle prevails; that's the nature of the world!
Born into the Blue Lightning Tyrant Dragon Clan, but not a direct descendant, he aspires to rise above the ordinary, for strength is everything.
The Thunder Dragon shed its mortal form and transformed into a dragon, gaining control over the thunder of the world.
It grows stronger against stronger opponents; its combat strength is unknown!
