The powerful commander Shen Xu and the young emperor Luo Ling are the most unlikeable monarchs in the Ling Dynasty. Shen Xu could lie on the dragon table and eat grape peels, while Luo Ling put the memorial on his lap to approve; Shen Xu slept on the dragon bed and Luo Ling slept on the couch, and even had to cover him with a quilt in the middle of the night. These two brothers who grew up together have such a tacit understanding that they don't need to communicate with each other, and they trust each other enough to dare to put the lives of their loved ones in each other's hands. But when the war broke out at the border, the conspiracy in the Western Regions came, and Emperor You's suicide note loomed, the daily life of laughter and curses was replaced by the iron-blooded battlefield. Shen Xu is called the God of War, and is also called the Human Slaughter. And Luo Ling sits in the court, and every decree is a silent support for his brothers. They hold the power to rule the world together, and they also bear the ancestral motto "No intermarriage in the world" and the fate that "men of the Shen family will not live to be fifty." Under the glory of the prosperous age, those unspoken friendships, the responsibilities that had to be shouldered, and the unfulfilled waits all turned into a plate of sweet-scented osmanthus cake with sugar under the locust tree of the Zhenguo Mansion. This is a story about trust and tacit understanding, protection and sacrifice. The laughter, anger, and curses are all filled with affection, and under the peaceful and prosperous times there are turbulent undercurrents.
