Is there any novel about being reborn as a prince?

The main character was a cultivator who was reborn as a prince of another world. Later on, he had an iron-blooded army under him. There was a large number of god-level soldiers under him. He even established a country called, and later, he even developed into the galaxy. After transmigrating to another world and being reborn into the royal family, he seemed to be born from an emperor and a palace maid. He wasn't valued and was later sent to a territory.(He had once stolen from the national treasury of many countries.) He developed the territory very well and the people of various countries yearned for it. His private army became the city management (similar to the monarch's reign in the other world) and caused the church to attack him. Later, the territory became independent and his original country was defeated. The original royal family came to seek refuge with him and eventually developed into the galaxy.
