Hehe, I recommend you a novel called "I Revived the Demons". It is a light novel, a fantasy novel. The main character was a demon king. He began to call on the vast demon race to open up land here, irrigate it with canals, pave it with tiles, and then carry out the industrial revolution to build a new era of demon kingdom! The details of the country's construction were very rich. The protagonist would continue to develop his country. What was even more interesting was that after he became the king, he brought a system that could help him manage the country better! I hope you like this fairy's recommendation. Muah ~😗
