In 2077, Chen Xi, a doctor of history and an expert in paleontological gene restoration, was involved in an accident in a quantum collision experiment while deciphering the simulated star map of the underground palace of Qin Shihuang's mausoleum. He carried a medical box containing telomerase activator and a copy of the bamboo slips of the Warring States Period, and his soul traveled to the sand dune in 210 BC. At this time, Emperor Qin Shihuang was seriously ill, Zhao Gao and Hu Hai were plotting to tamper with the imperial edict, and the restoration forces of the Six Kingdoms had secretly contacted the Xiongnu in an attempt to overthrow the dynasty while the Lord of Qin was critically ill. Chen Xi relied on modern medical knowledge and historical predictions to discover that Ying Zheng's illness was not only due to strain, but also related to long-term use of mercury-containing cinnabar and genetic shortening of telomeres. The telomerase technology he carried was the key to cracking the "destiny".
