Here's the official translation of the novel but I didn't read the current chapter here since there's less than 300 chapters translated and the current chapter's 600+.

So in the novel, the 'Friend of Nature' skill which makes him speak to the animals wasn't this detailed. In the novel, he could only talk to the animals once he touches them(would upgrade in the future so he would be able to talk to them like this in the manhwa) which is why there was a scene during the meet up with the minotaur king where he touched him to talk to the minotaur king. In the manhwa, he could talk to them and everyone was surprised but in the novel, they weren't really surprised as if Sejun understood them from the beginning. As for Keung calling him dad, it did happen in the novel since in the future, Keung would be famous for being the great black dragon's son(Sejun was mistaken as the great black dragon). However, Sejun thought 'Keung is still young so as he grows up, I'll slowly let him know that I'm not his dad' but I don't think it would happen since I've read to the current novel chapter and Sejun treats Keung as his real son. So unlike in the novel, it wasn't really detailed like the manhwa since author can't really express each animal's feelings by text because there's a lot of them I tell ya, but of course makes you imagine everything so I agree with this change but still worried since some details keeps on changing like the 'Friend of Nature' skill.
