It's entertaining enough to keep my attention. That's all the matters to me. I like these types, where the MC has to accept disciples. There isn't enough to really criticize, the grammar and spelling is fine. Maybe someone could argue you should've expanded on when and how the actual MC took over the body of his predecessor? It just jumped straight into the action, but I actually prefer this over some long info dump at the beginning. Anyways, I look forward to the more.
