Lu Zeyan, a modern special forces instructor, accidentally transformed into the good-for-nothing emperor Jiang Xubai in the novel - the emperor's uncle. His biological mother died young and he was powerless. He was despised by the royal family and ridiculed by all the officials. He is the most cannon fodder character in the book. But he didn't know that the original owner was hiding something unknown: he was the "Dark Lord" who secretly cultivated dead soldiers and controlled underground forces; he was the "General Polu" who was proficient in the art of war and had made great military exploits; he was the "Mr. Mystery" who could deduce the general trend of the world. After passing through the book, Lu Zeyan relied on modern skills and the original owner's vest to protect the heroine (Song Qinghe, the ostracized daughter of an aristocratic family) during a crisis at a palace banquet. He accidentally exposed his vest. From then on, he started the road of being slapped in the face. From the good-for-nothing emperor uncle that everyone despised, he counterattacked and became a powerful being. He even changed the original owner's cannon fodder fate and joined hands with the heroine.
