Perfect: I, the Golden-Horned Giant Beast, Devours the Immortal Ancient Battlefield

Traveling through a perfect world without a system, he was reborn as a pure-blooded golden-horned behemoth. He was also mistaken for the "dragon species of later generations" by the ancient true dragon, and was dragged into the melee front line of the Immortal Ancient War. Looking at the foreign army in front of me holding precious mithril and tempered magic sword... Hunger comes for no apparent reason. The golden-horned beast swallowed a mouthful of saliva and grinned at 180 degrees. "What kind of foreign immortal royal family? It's just a pack of crunchy sharks that are smelling delicious!" In this life, I am not trying to become an immortal, I am just trying to eat up everything I see!
