The story takes place in the early days of the War to Resist US Aggression and Aid Korea, and the Kuomintang smelled a hint of regaining power, so it was ready to move and tried to ** the mainland. The Kuomintang bandits in Dayin Mountain also began to actively cooperate with Taiwan and wreak havoc at home. The People's Liberation Army (PLA) decided to exterminate the bandits, and while sending additional troops to suppress the bandits, our party's 701 intelligence agency stationed in the southern mountainous areas, under the command of Dean Tie and Deputy Director An Zaitian, actively prepared for radio interception and decipherment, and mastered the rules of the activities of the enemy's special radio station.
The victory of the People's Liberation Army in the battle against bandits made the Kuomintang wake up to the fact that the radio stations were completely under the control of 701, so they changed the frequency used to send messages, and for a time all radio stations disappeared without a trace.
The 701 was unable to listen to the signals of the enemy's special radio stations, and the PLA was like losing its baton, which brought tremendous difficulties to the work of suppressing bandits. In order to break the situation, an operation called "Deep Sea Breakout" kicked off. However, in the vast sea of radios, it is like looking for a needle in a haystack to find an enemy special radio station that has changed its frequency. 701 recruited a large number of listeners from various relevant departments in an attempt to relocate enemy stations, but with little success.
Dean Tie and Ahn realized that it was imperative to find a hearing wizard who could accurately identify the enemy's special enemy station among the many radio signals. After screening, 701 locked in a magical tuner, Luo Shan, nicknamed Luo San'er.
An Zaitian and Director Jin of the Security Department were ordered to go to Shanghai ** College to find Luo Shan, but the plan was ruined by the enemy first, and the tuner Luo Shan was brutally killed by the enemy, and the progress of the work fell into a stalemate.
