In the fertile central part of the continent, there was a powerful empire called "Liu Li".
After three generations of hard work, "Liu Li" conquered three-fifths of the land, and the rest were small countries and mountain tribes that were willing to surrender.
"Liu Li" is an open country, where love and desire have no moral constraints. Of course, this does not include sex between blood relatives, which is expressly prohibited by law.
Because of this, the third-generation emperor also attracted beautiful women after having an imperial husband, which led to a civil strife in the palace that affected both the government and the public. The powerful empire was almost destroyed.
There was a prophet who said that Liuli declined in three generations, revived in five generations, and became famous in the mainland for thousands of generations. The decline of the three generations seems to have been fulfilled, but the revival of the five generations is still unknown. But the fourth-generation emperor, who had achieved great success but had mixed reputations, was mysterious and unpredictable.
