I am looking for a novel where the mc is a ruler. He advances civilization from the stone age to the interstellar age and beyond, not like RTW where they are just entering the information age but far beyond it. Think of the civilizations in 'The Legendary Mechanic' although the technology was mostly for war. The civilization should at least advance to interstellar. Note: Do not mention 'Release the Witch' & 'Genjitsushugi Yuusha no Oukoku Saikenki'.
