The Overpowered Protagonist System, But It Came Too Late

Blurb:

The Dragon-Aspiring System arrived half a month late and thought it wouldn't matter.

But that brief half-month was all it took for the male lead, who should have slapped the faces of all the hidebound, conservative Go academies and led the Go world into a new era, to become the Go Sage's kept pretty boy, all thanks to his outstanding looks.

Male lead: Why bother playing Go? You put in all that effort and still barely make any money. Better to marry the Go Sage while you're young and skip thirty years of struggle~

Dragon-Aspiring System: ?

Male lead's POV, younger love interest, Go story, science-fiction alternate setting. The competitions and everything else are made up, so please bear with me~

An eighteen-year-old, romance-addled male lead born in the AI era who transmigrates into another world X a thirty-year-old great villain and Go Sage, whose sanity has been shattered by the recent AI onslaught and who is on the verge of a breakdown

P.S. The System is the only Dragon-Aspiring one in the whole book.

Theme: Every trade has its masters.
