OmniArch

Aiden transmigrated into the body of a King of a kingdom that and a land that shouldn't exist on Earth.

Being on Alternate Earth, he received a System called OmniArch.

[ Everything Up To You Host. The system will not force you to make your country the strongest, the best, or anything. If you want, then it's your will and even if you want to establish a mediocre country, then the system won't stop you]

" Well! I will establish the Kingdom as I wish, then”

Aiden had a big smile on his face and his imagination started to stir.
