A modern history buff accidentally traveled through time and became Xu Fu, an alchemist who sent a letter to the Emperor Qin Shihuang in his 28th year to travel eastward to seek immortality.
He couldn't bear to look at Ying Zheng, the most talented emperor in the palace, but he was obsessed with immortality and eventually died violently in the sand dune. I couldn't bear the death of the second generation of Qin Dynasty, I couldn't bear the collapse of the foundation of the great unification of China, and I couldn't bear that this emperor, whose achievements were as great as those of the three emperors and five emperors, was fooled by the alchemists in his later years and died in the chaos of the country.
He has no system, no anti-Qin, and no self-reliance. He takes the name of Xunxian, takes over the important task of searching for medicine, and protects the Qin every step of the way. Using the excuse of searching for medicine, they asked for ships, warriors, craftsmen, and agricultural supplies. They took advantage of the opportunity to cross the Yellow Sea and the East China Sea, occupied Liaodong, captured Korea, expanded Japan, enslaved the Japanese, reclaimed overseas fertile fields, built a maritime army, and built granaries and strategic backing for the Qin Dynasty.
He abandoned highly toxic heavy metal elixirs and used modern medicine to regulate the body of the First Emperor, helping Yingzheng to live longer. He used fairy omens to provide advice to protect Fusu, suppress Zhao Gao's traitors, and block all hidden dangers of Qin's death.
Everyone in the world thinks that he is obsessed with seeking immortals, but they don't know that he is an alchemist and performs the duties of a national scholar. The so-called elixir of immortality is never a pill, but the eternal destiny of the Qin Dynasty and the immortal reputation of the First Emperor!
He protected Ying Zheng's death, helped Su successfully succeed to the throne, stabilized the Central Plains, suppressed the Xiongnu, conquered Baiyue, and expanded the four seas, allowing the Qin Dynasty to truly realize the second, third, and eternal life, to be passed down endlessly, and achieve an unprecedented great unification and prosperity!
