Jiang Ye, a tour guide who is terminally ill, is bound to the plane travel system and continues to live by taking tourists through ancient times. Jiang Ye took tourists to deceive the First Emperor of Qin, offering potatoes, gunpowder, and papermaking technology to help the Qin Dynasty become stronger and more prosperous than the Han Dynasty. Jiang Ye went to the Anxi Protectorate of the Tang Dynasty and joined forces with modern military fans to send supplies, weapons, and medical care to the "white-haired soldiers" guarding the Western Regions alone, rewriting a tragic history.
