After He Xuan pretended that he accepted that nonsense, the invader started broadcasting about something called "magical core" and how he need to "feel it via your blood" and the not last and definitely not the least: "even if you are a half-mudblood, you still must be able to do that". Harry was not sure what most of those words meant, including "mudblood". And the boy believes that that bastard had real fun, explaining it. That was a horrible experience. That stranger is even a bigger bastard than Hua Cheng.
