Jobless Reincarnation: Reincarnated as Pacus!

Note: Do not grab the three primary colors, no system. An ordinary middle-aged man rescued a red-haired girl when he was unemployed and his life was at a dead end. Strange things happened the night after she was adopted. He opened his eyes again and was reincarnated into Pacus. After a series of adventures and legendary changes in royal power, he became an important factor in opening up the future.
