Quick Travel: Red Baoguo Road

12 Mysterious notebooks spanning thousands of years actually contain the protection codes from ancient crossbows to the future interstellar! Because of his "air-distance conversation" with Su Wan, a female arrow-caster who broke 127 bowstrings thousands of years ago, and Chu Yao, a female general who guarded the border for three months without giving up food, she used the wisdom in her notes to reveal hard-core operations: using the "mulberry fish pond" idea to solve the energy consumption problem of deep-sea probes, she trembled on the hospital bed and wrote down the lunar energy closed-loop plan, allowing the original intention of "protecting the people" to move from the ancient battlefield to the interstellar frontier! After her death, she left behind a shocking legacy: her notes were collected in the National Archives and became the "Bible of Serving the Country"; the base of the bronze statue "holding the position is serving the country" struck a chord with countless people; her grandson transformed from a child holding a crossbow model to an aerospace engineer; young people in the exhibition hall copied the oath of "We have secured this baton", and let the guardian fire shoot from the crossbow to the stars! The passionate narrative that breaks time and space tells you: Serving the country is never a slogan! It's Su Wan's determination to still lift the hammer after breaking the string 127 times, it's Lin Yue's determination to still calculate her energy balance despite being critically ill, and it's also the tenacity of every ordinary person to stick to their posts – this relay of original aspirations that spans thousands of years, from ancient battlefields to interstellar space, is always exciting!
