Austin, a young construction worker, falls from a twenty-story building while working on an incomplete apartment complex.Soon after, he wakes up in the body of a fourth prince who had been poisoned by one of his brothers.As though that wasn’t scary enough, Austin later discovers that he has somehow become entangled in a dangerous political situation where his brothers would do anything to become the next emperor.However, this turned out to be the least of his problems because Austin realizes that, unlike his three older brothers, the fourth prince had never once taken a liking to combat or training, making him the weakest out of the four princes.So, how is Austin expected to survive in a world filled with magic, monsters, barbarians, demons, and an internal battle over the succession of the throne?With a long, depressed sigh, Austin groaned as he lay on his bed and stared sightlessly at the ceiling.“Ugh, what am I going to do now?” he pondered.
