His Majesty's Bedroom Has a Door

Yu Qi, who traveled to a small country in another world and became a prince, took over the throne very smoothly. He thought that his life from now on would be nothing more than farming, developing the economy, and trying to climb the technological tree from scratch. Unexpectedly, a door that appeared in his bedroom completely changed his life. From then on, Yu Qi not only had to be busy with the government affairs of his country, but also took time to explore other worlds. He was so busy every day that he never got tired of it. It's all worth it... Yu Qi thought as he inspected the army with a fully automatic rifle in his left hand, a sacred cross in his right hand, a colorful dragon scale crown on his head, and a blue sky phantom sword hanging at his waist.
