Chapter 719: Dragon Clan Academy
Black dragons prefer to dwell in swamps and feast on rancid, acidic food. This is something that Muria finds intolerable. He cannot accept the dietary habits of the black dragon, and so all of the black dragons in Sinapus change their inborn habits according to his preferences.
After the initial difficulty, the black dragons' perspectives shifted according to Muria's will due to improved living conditions. This led them to believe that they are superior dragons. They began to despise their own kin who lived in the wilderness.
Their accompanying habits of dwelling in swamps and fermenting food before consumption were also scorned. They saw these habits as symbols of barbaric ignorance, as they felt that noble dragons should refuse to live in disgusting swamps and eat such nauseating food.
