On the day Zhao Heng burned the family tree, he was wearing a dragon robe. A modern archaeologist travels through troubled times and ascends the throne as emperor, but he realizes that he is the orphan of an exterminated royal family. Secret guard Su Yan was ordered to assassinate him, but in repeated confrontations, he discovered that he knew what "inheritance" was better than anyone else. The chief assistant Xie Wujiu burned the genealogy to force him to wake up, the proton Pei Zhao used his hand to seize power, the female official Liu Rumei painted the real picture with blood, and the Taishi Cui Yan secretly wrote down the truth. When the dragon robe is stained with blood and the family tree is rekindled, what he wants is not to restore the country, but to make this man-eating world no longer have a family tree to burn.
