The path through the ancient forest was quiet and Xuan Hao did not manage to spot any other Nascent Soul Realm beast like the group of wolves from earlier, so they were most likely one of the first groups of demon beasts inside the secret realm that had ended up being unsealed earlier than expected.
This was good news for Xuan Hao, as he would not have to deal with all sorts of flying demon beasts coming up to attack him while flying over the ancient forest as he made his way towards the small palace located at the border between the Nascent Soul realm area and the place where the few Domain Lord Realm demon beasts inside the secret realm were located.
Hopefully what the treasure hunter had said about the small palace was true and he would be able to gain quite a lot from his visit to the secret realm!
