The Ultimate Commander: I Build a Nation on the Ruins

[Reborn + System (minor role) + No Female Lead + Political Scheming + All-Round Development + Statecraft + Reaching the Top + Slow-Burn]

The protagonist was a fourth-year economics student on Blue Star. He worked so hard on his thesis that he died from exhaustion.

He was reborn in the body of a man named Karl Reine, in a parallel world with no connection to his original one and a completely different history.

With the System’s help, the protagonist reached the top in a single day. Then the System suddenly malfunctioned, losing all its functions except the most basic ones.

Through his own efforts, the Host transforms a small country torn apart by war into a world power.
