im mad to even why he walked up and asked them he should had know after granny hes not that strong. also he kinda knew something was up

I find the world to be great and many characters are great but i had to stop about chp 120. our MC is told how weak he is and almost dies multiple times before, yet he took the risk to fight knights he just saw fight very well. even after he thinks that old knight that trained his dad is a bad dude he walks right up to them and ask them , the dragon told him many times to not get in any dumb things until hes stronger. To me the MC is odd, we are told he likes to read and study at the start of the story, yet he seems dumb. after meeting granny he should had know he is not close to being that strong
