I'm Divining a Star, Feeding the Dragon with Stars

The fortune-telling prince Latte, who originally broke off his engagement with the princess of a neighboring planet, was inspecting the border area for his father, but the fierce Princess Garner of the neighboring planet Demon King drove a warship to come to reunite with him. Of course he was unwilling to do so. The king of the Demon King himself is extremely cunning and cunning. If his father hadn't been so resourceful, the fortune-telling star would have fallen into his hands long ago. Unable to reconcile, Garner could only go back and follow his uncle to launch a short and violent coup, killing his father, successfully ascending the throne and becoming queen. After learning that the Demon King had passed away, Latte saw an opportunity and went to the Demon King himself to seek reconciliation. But he didn't know how complicated it all was. He only wants to get a "feng shui treasure land" on Demon King first, and plans to get married first and then investigate everything. But slowly, he discovered that this new queen was too powerful, too smart, too, right? Fortunately, he has the "Star Energy Dragon Raising" system that can help him train his dragon and gain strength.
