Меня считали мусором, но я превратил ржавый корабль в боевой крейсер!

In a past life, I lost everything because of my weakness. In this life, I returned to repay my debts. When my family was despised and the world's most powerful navy tried to destroy us, I proved that the difference between a pile of scrap metal and a super-combat ship was my intellect. This is the story of how I went from being an outcast to becoming a nightmare for the world's powers. Don't miss the most legendary 'counterstrike' in the history of naval combat!
