Gu Weijun, a doctor of quantum physics, accidentally traveled to Tsinghua University in 1930 and restarted nuclear physics research as a "returned scholar." He calculated the uranium enrichment formula with his left hand and improved the rifling of mountain cannons with his right hand. During the encirclement and suppression campaign by the Japanese spy Fujiwara Ayahime, he formed an "iron triangle" with the underground party Chen Shusheng and his assistant Lin Wanyang. The bloody formula on the wall of the air raid shelter, the heavy water model in the Dunhuang murals, the accelerator drawings in the wreckage of the Hump Route, the scientific fire is tempered in the flames of war. When he discovered that the unfinished kiss in 1937 turned into quantum data in a modern collider, he realized that he was already an "observer" of history...
Concept: A doctor of physics who travels back to the Anti-Japanese War uses quantum entanglements to decipher the Japanese nuclear weapons conspiracy. Between the beacon equation and the bloody erotic book, it collapses into a superposition of life and death across time and space.
