Qin Zheng transmigrated into the role of the Princess Consort, but Qin Zheng, an engineer dispatched to a foreign country, didn’t get the script for a palace drama, nor did she have the chance to experience the luxurious life of a Princess Consort. Because, the nation had perished. A eunuch held three feet of white silk and said, “Your Highness, the city has fallen. Please leave with dignity.” Qin Zheng: “…” What kind of beginning was this?
