One is a remnant of the previous dynasty, living an ignoble existence; the other is a young leader of an ancient clan, mediocre and incompetent. Let's see how these two people can make the world chaotic and peaceful. The remnant ascended to the throne, the mediocre leader became a general, and he only assisted one person in his life. The prosperous age began from that moment on.
Intention: The two of them work together to win the country, take revenge, and let the people live happily.
