It's not like Xue Ren is picking a fight with those lightning students!
Simply because it's their first adventure together, Xue Ren was hoping that his daughter would experience the beautiful scenery and time as well. Going here, Xue Yu was naturally enjoying the nature that was quite lacking in his world and her birth world.

For her, Xue Ren is the best! And he naturally knew that this is how kids think. Furthermore, Xue Yu was always going for him, her little hands trying to hold his clothes at every possible moment.
So Xue Ren's desire was simple - to show his daughter who is the best.
