Developing a Fiefdom Starts with the System

"What? Am I the fourth prince who is the direct descendant of Empress Yuan, or am I the second in line to the throne?" "The prince has been named, he is my biological eldest brother, he is both civil and military, and he is very kind to me?" "But my mother died three years ago, so Concubine Qi, who has always coveted the throne, gave me a barren fief that was half a swamp during the fief drawing ceremony?" Chen Yuanying, who should have been angry, secretly laughed. "System, I must go to the swamp before I can activate my fief system?" "Yes!" "Okay, I'll take over immediately!" Moreover, he dragged the two concubines born to the imperial concubine Qi with ulterior motives to join the feudal clan! No matter how rich your fiefdom is, can it rival this king's system? The sky is high and the emperor is far away, and I am just enjoying my life!
