When I graduated from high school, I tore up my admission letter and decided to join the army. Five years later, when he returned to school, he got a mysterious bamboo slip in the ancient book restoration class. When my classmates laughed at the sloppy seal writing, a chill ran down my spine - I had seen exactly the same writing during a top-secret mission in the military camp. As the bamboo slips were restored, the first line made the professor look pale: "In the forty-second year of the First Emperor, Xu Fu returned from the eastward journey..." According to historical records, Qin Shihuang only reigned for thirty-seven years. Late that night, screams came from the library and the bamboo slips disappeared. The surveillance showed that the last person to leave was wearing my military uniform.
