In 219 BC, the alchemist Xu Fu and his deputy Qi Heng embarked on an eastward journey with the fleet to find the "elixir" for Qin Shi Huang. On the way, a mysterious tsunami plunged the fleet into a desperate situation. Qi Heng accidentally came into contact with a swarm of glowing jellyfish in the Ryukyu Islands. His body underwent a strange mutation and he gained the ability to live forever. However, the cost was extreme sensitivity of his pain nerves and the need for regular exposure to special radiation fields to maintain cell activity.
Since then, Qi Heng has traveled through thousands of years and been deeply involved in key historical processes. During the Three Kingdoms period, he transformed into a disciple of Hua Tuo and witnessed the abnormal bioelectricity phenomenon in Cao Cao's skull when he executed Hua Tuo; during the Anshi Rebellion, he rescued Yang Yuhuan and discovered that his meteorite necklace could trigger resonance in his own DNA. During the Northern Song Dynasty, he and Shen Kuo worked together to develop a magnetized mercury device, established the first immortal shelter underground in Kaifeng, invented special ink, and hid secret chapters in "Mengxi Bi Tan".
During the Industrial Revolution, he disguised himself as a British businessman, exposed opium warehouses, and triggered the opium ban in Humen. However, he was hunted by Queen Victoria's agents and accidentally discovered the East India Company's human telomerase experiment. During the Anti-Japanese War, he deciphered Japanese military messages as a cryptologist, discovered the secret experimental report of "Eternal Life Unit" 731, and found a Qin Dynasty bronze radiation device in an underground icehouse in Harbin.
In modern times, the suspense of whether there is an ancient virus that can rewrite human genes is hidden in the mercury vortex in the underground palace of Qin Shihuang's mausoleum, once again involving Qi Heng in a huge crisis. His experiences of the past thousand years are intertwined with modern conspiracies, and a journey of historical suspense and scientific exploration across time and space begins.
