The problem now is that with such a reputation the Magical Britain’s society has particular expectations from their "hero" and may urge him to miraculously solve their problems again, which He Xuan disagrees with. And if they don’t want to listen to his point of view? Well, this one has never been too patriotic, the world is big and during the time at Tonglu Mountain he gained some experience in learning a completely new language, so immigration is unlikely to be the unbearable problem to He Xuan.
