In Chinese history, how would an unparalleled hero with outstanding achievements be able to "re-establish the royal family", an Optimus Pillar who held 80% of the empire's military power and was relied upon by four generations of emperors, plan for the future of his family? It's not about leaving behind the art of slaying dragons, nor is it about passing down the unparalleled art of war. Instead, after a grand family banquet to celebrate his complete surrender of military power and return to the countryside, he pulled his most beloved son, the current prince-in-law Guo Ai, into a secret room alone, and in an almost crazy and decisive tone, issued an order that could shame the entire family and bring shame to the ancestors - to spend money, to become a libertine who is the most unsupportable in the eyes of the world. This scene is not a ridiculous story fabricated by historians, but the most real and thrilling survival game that took place in that special era when the Tang Dynasty fell from its peak and was reborn in blood and fire. Lin Xiao, a modern civil servant who just wants to "retire safely", is forced to work in the most dangerous center of power in the Tang Dynasty. As Guo Yan, the sixth son of the famous Tang Dynasty general Guo Ziyi and the consort of Princess Shengping, he pretends to be crazy and indulges in luxury to carry out his father's ultimate mission of "self-destruction and preservation of the clan". However, he is accidentally involved in the vortex of the princess's true love, the secret war in the court and the survival of the family. In the end, in the pull of emotion and intrigue, he finds a way to live a higher level than "survival".
