I Traveled Through Time and Became a Coward, I Slapped the System in the Face with My Saucy Operation

Others traveled through time to be Long Aotian, but I became the worst time traveler in history. I was bound to a stupid system, and each task was more outrageous than the last: expanding the harem, ceding territory and paying compensation. If I couldn't complete it, I would become itchy and cross-eyed! Fortunately, I was clever and used erotic pictures to attract the old gods, won the war, and even used the exclusive space for free. See how I can make the most of my life under this ridiculous system!
