After transmigrating, Tselmeg found out that he was reincarnated into Harry Potter world. The issue is that he become the grand-nephew of the great wizard of all time except Merlin himself, Albus Dumbledore. English is my third language. And just comment about this book. It would motivate me and effect to how far the story goes on. Minimum 5 chapter a week /Mostly on Saturday and Sunday/
