Igye Geomwang Saengjongi

A man named Hanbin Ryu, recently out of the military and without direction, is abruptly sent to a different world. He is given a system meant to aid his survival and development, but it is riddled with errors, trapping him in the tutorial phase for more than two decades. After finally being freed from this prolonged ordeal, he discovers that hostility now exists toward people like him from other worlds. Struggling with his low level and incomplete training, he must find a way to survive in this changed environment.
