Nancheng No. 1 Middle School is celebrating its 100th anniversary, but the campus is caught in a confrontation between camps: the student union imposes strict management, clubs and sports teams are in conflict, and preparations for the School Anniversary Cup have turned into a battlefield for internal fighting. Lin Yan, a first-year high school transfer student, joined the school history museum despite the criticism from "connected households". He just wanted to win a scholarship to prove himself, but accidentally came into contact with dusty old things, and awakened the golden finger of the old things decoder.
Touch old photos and old maps to analyze key coordinates, hidden rules and task prompts. This is limited to three times a day and will expire the next day if it is not verified in practice. Lin Yan followed the clues and unearthed an undelivered Anti-Japanese War truce letter deep in the school history museum, which revealed the dusty past of Gu Xingzhou, a student rescue team: During the war, he tried to use the letter to obtain a ceasefire to save people, but unfortunately failed due to misunderstanding, leaving behind a set of "peace rules" to tame the conflict.
In order to solve the mystery of school history and quell the campus confrontation, Lin Yan teamed up with Xu Zhixia, who was very capable of execution, and won over Zhou Ye, who was passionate about protecting shortcomings. They faced Song Jinghe, the vice chairman of the student union who was proficient in planning, and solved the mystery step by step under the secret protection of Teacher Du from the school history museum. They used historical clues to counter camp disputes, transformed vicious confrontation into collaborative competition, and finally re-enacted the armistice agreement of the year on the School Anniversary Cup stage. Not only did they lead the team to counterattack and win the championship, but they also made the whole school understand that peace is never a slogan, but enforceable rules and consensus. The teenagers also completed their growth and transformation while solving the puzzle.
