Report This System and I Will Be Chased and Fed by the State

Chu He, a graduate student in the Department of History, just wanted to spend the rest of his life as a salty fish, but accidentally activated the [National Games Sign-in System]. The check-in locations are actually [J-20 Hangar], [055 Large Destroyer Bridge], and [Inside Nuclear Submarine]! It's simply impossible for an individual to complete it! Under the threat of "obliterating the system if the mission fails," Chu He made a phone call to Yaoyaoling: "Hello, comrade police? I picked up a system and want to hand it over to the country!" Since then, Chuhe has become the country's highest-level secret. In order to get him to sign in, the entire state machine worked like never before. Yingjiang: "Why did Rabbit suddenly have a technological explosion? Who are their top scientists?" Chu He: "Don't ask, just ask as a history student."
