At this moment, the person from the other world crossed over and successfully occupied this body, becoming Robinson.
When he came to this world, he obtained the system.
The system would occasionally give him some missions. As long as he built the fiefdom he occupied, he would receive a certain reward.
With the help of the system, Robinson began to develop on his small fiefdom. He built towns, developed the population, recruited mages, trained soldiers...
Under such circumstances, his fiefdom was originally a small city of no more than two to three thousand people.
Now, in just a few short years, it had become a large city of considerable scale.
It had a population of more than 100,000!
The city was also well-planned. The roads were straight and clean, and the houses were arranged in an orderly manner.
The people of the fiefdom respected him very much.
