- Description from Novelupdates

Before dying, the blind beauty Xiangnu accidentally entered an infinite escape world.

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? In order to avoid being forced to commit su*cide, Qin Zheng had no choice but to go to the bed of her half-dead husband, the Crown Prince, and pretend to be deeply affectionate, shedding a few tears to delay time. Emperor Chu Chengji, founder of the Great Chu Dynasty, was valiant and skilled in warfare. He conquered the northern barbarians and drove out the southern savages, ushering in the prosperous era of Xuan Chu. He spent his entire life in battles, without a wife or concubines. Consequently, after his premature death, only a young scion from a collateral branch was selected to succeed him. He departed during the peak of his prosperous reign, only to open his eyes and find himself at the time of his nation’s demise! He was reincarnated as the current Crown Prince, his own nephew of many generations. Learning that the territory he had opened up in the past was directly lost, the Emperor of the founding dynasty couldn’t help but laugh in exasperation. How useless were these descendants? Back then, he could establish this long-standing empire single-handedly, and today, he could rebuild it! As for this stunningly beautiful Princess Consort, who cried so pitifully in front of him, the Emperor of the founding dynasty was extremely disdainful: “Women would only hinder his speed of restoration!” Later, the Emperor of the founding dynasty would knock on the door of the Pepper Room every night and ask, “Azhen, can I come back to sleep?”

Ling Chen was a peerless master hiding within the city hustle as a nobody-courier, until he stumbled into the world of the beautiful CEO, Nanrong Wanqing, the 'untouchable flower' of Donghai City, due to one of his work assignments. From then on, watch as his life is thrown into an exciting disarray!
