Lin Yuan sat on the back of the Divine Travel Black Swallow and couldn't help criticizing. It would be fine if it wasn't comfortable to ride on the Divine Travel Black Swallow—the crucial thing was because it was hard on the butt.
The Divine Travel Black Swallow was rather small, and its body very light. Most of the feathers were gathered on the wings, so its back only had a thin layer of woolen feathers.
In fact, the Divine Travel Black Swallow wasn't suitable for riding because it was too fast. There were plenty of avian feys that were suitable for transportation in the Radiance Federation. The Divine Travel Black Swallow might not be a comfortable means of transportation, but it was definitely the most popular avian fey.
The distance between the Radiance Federation's major cities was too far, and if time could be saved during travel, a little discomfort could be overlooked.
