Travel Through the Book and Return to Taihang to Catch Enemy Agents

I am a modern old lady who wears books and is taken by a small high-speed train to a parallel space where a military factory was established in the mountains of Taihang in 1966. Xiao Li, a veteran, was taken to the bottom of a cliff by a snake to pick wild fruits - I became Xiao Li's stand-in... I, Section Chief Li, am actually the incarnation of Na Yanzu, a student from the Northeast, in his previous life... Interesting stories abound... I have been working and living in the mountains with the space golden finger high-speed train for more than twenty years. During the time when the ordnance workers were building factories and vigorously producing military products to support the anti-American battlefield, I grew from "Little Li" to an officer of the Security Section and "Section Chief Li" of the Security Section. I was brave and tenacious, catching enemy agents who entered the military factory to cause sabotage, and protected the safety of the military factory... But I have always been alone, suffering from loneliness... When the factory was at a low point, my imagination opened up and I offered suggestions to get out of trouble - and was also brought back to modern times by the Golden Finger High-Speed Railway... I saw the future...
