Don't get me wrong , I was relieved to see a happily ever after for them, I'm just a bit confused because it doesn't seem to go along with what was previously said. They had stated in ep 36 that the person transferring qi would either die or lose their martial arts. It seems in the end that neither happened to Kexing. His hair turned white but he's still very much alive and doing martial arts with Zishu. I'm glad to see this but I can't help but wonder if I missed something because this seems contradictory .
