Chen Yanqing, a son-in-law from a poor family, was bullied like a dog by the powerful people of the dynasty, but on the day he ascended the throne, the civil and military officials of the dynasty knelt down to worship his name. He used a marriage contract to lurk in the Hou Mansion, used Shen Zhiwei's hands to control intelligence, used Huo Jiuyuan's troops to intimidate the border, and used Liu Huaiyin's secrets to restore the ancestral system. Zhao Chongli corrupted the country due to his corruption, and Cui Mingzhao's old thoughts were hard to get rid of, which became a test on his way to the throne. When the dragon robe was put on him, no one knew that the once-scorned son-in-law was the soul of an emperor from the previous life who had returned - and now he wanted to reshape this thousand-year dynasty with the blood of a poor family.
