A programmer from Blue Star dies while raiding a guild dungeon, then transmigrates to another world.
His late-arriving golden finger seems like it may never show up. In the early days, he scrapes by using a set of physical training techniques given to him by his benefactor. Later, he draws on the memories and abilities of his past life to format magic, create his own golden finger, develop an operating system, and build magical applications, gradually rising to the top of this other world.
A great war twenty thousand years ago shattered the entire continent into pieces. There are hundreds of countries, both powerful and insignificant. Though their numbers have not fallen much over time, three major powers have gradually emerged: Dongbolei, House, and Xi.
Xi is currently ruled by a group of dwarf tribes who invaded and have held power for four hundred years. Their grip is beginning to weaken. The streets are plagued by thugs and bullies, local officials are corrupt, and government posts are bought and sold in the imperial capital. The people of Xi suffer terribly and complain bitterly. In particular, many of the mixed-blood people born after the great war twenty thousand years ago have been reduced to slavery, living worse than pigs and dogs.
Starting out as a lowly magic apprentice, our programmer works his way up through his own efforts, eventually dominating a region and becoming one of the most powerful people on the continent. But his rise brings new problems: because of him, the demons from twenty thousand years ago have been resurrected... What will happen next???
