I still don't get it LOL I'm terrible at understanding hints and stuff like that 
After sometime, Neji get's up from being exhausted from hitting trees and starts to hit more trees this time with chakra being expelled while hitting the trees. While hitting the trees with chakra, Neji noticed that the tree takes significantly more damage and fell down at a way faster rate. Having the practice from earlier, he keeps hitting multiple trees and in succession keeps knocking them down. "Man I wish I was using chakra beforehand" As Neji laughs, he looks at more trees and continues hitting them. After about the whole day had passed, he fell onto the ground completely exhausted from using too much chakra hitting the trees all day. "Well I did it sensei!"
