I received a review copy of this book. Portal Jumper is book 5 in this series, and it's a lot of fun. Orcs galore, explorations, levels, training, and more. Just what a LitRPG story should have. Looking forward to the next one.
Somehow I lost interest in the plot, be it due to the genocide, the plot giving benefits to be a racist murderer or the repetitive dull fighting style.
