I Am the Great Lord of Another World

Traveling through another world with the game card system, he became the lord of a desert land. In his previous life, he was just a small person. He was tired of running for life and had a girlfriend. However, when it came time to talk about marriage, he fell down before buying a house. In this life, I want everything I look at to be my territory, and I want this world to surrender under my feet. For this reason, I will not hesitate even if it means that I will never recover.
