Leaving the Star Shattering Sect, Xuan Hao decided to use a flying demon beast for the first part of his journey. This way, he would be able to recover his strength while also moving towards his destination at the same time.
Although this was slower than him flying himself, he would be able to recover his strength far faster this way and he didn't really expect to encounter any dangerous situations before reaching the core of the Sky Empire.
Even if he ended up encountering a bandit group along the way, most bandit groups would not have any strong demon beasts available to them… And that was not mentioning that the flying demon beast he was using had reached the Nascent Soul Realm!
Ordinary flying demon beasts would not be able to catch up to him, let alone try and pick a fight with him!
