Li Guodong promoted the Red Army's policy of preferential treatment of prisoners in the prisoner camp, and made it clear that they would not torture or kill prisoners. Whether it was the Kuomintang or the Communist Party, the common enemy of both parties was the culprit who owed the people a blood debt, and was also the landlord who exploited the people. The Communist Party intendedIn order to let the poor people stand up and make the decision, if they want to stay in the Red Army, they will be very welcome. If they don't want to, they can also receive two silver dollars and go home.

In addition, Li Guodong mentioned that the Red Army was in urgent need of communication talents, and Lu Shaowu resolutely chose to stay. Zhou Mo was unwilling to let a black sheep like the division commander regain his freedom, so he reported his identity on the spot and watched him being taken away.It was precisely because Zhou Mo heard Lu Shaowu's words and Commander Wang persuaded him to stay that he agreed to stay and serve as a teacher in the training class.

Because Zhou Mo was once a member of the Kuomintang, Shi Lanqing and others complained about her. Living in the same house made the atmosphere particularly awkward.When sleeping in the middle of the night, Zhou Mo sent a telegram to Tao Ge in his dream, tapping the password unconsciously with his fingers, which made Shi Lanqing very unhappy.Cai Zejuan and others received the information and recorded a lot of useful content. They believed that understanding the movements of the Kuomintang would be very helpful to the soldiers of the entire army.

Tao Ge spent all his sleep and food designing the password and used Green's formula. Huang Jibi thought it was not complicated enough. He always felt that there must be math masters on the Communist Party's side.Soon, Xinji received a new telegram confirming that the Kuomintang had established a general headquarters for the suppression of bandits in Hubei, Henan and Anhui provinces, with Chiang Kai-shek personally serving as the commander-in-chief, and would launch the fourth siege against them. Cai Zejuan informed Xu Dapeng to quickly send the news to the headquarters..

The organization approved the list of the first batch of telegraph operators, and six people including Shi Lanqing, Du Hong, and Wang Xiaojing successfully graduated and became official telegraph operators.Cai Zejuan suggested setting up a maintenance team, which would be mainly responsible for the maintenance and upkeep of the equipment. Zhou Mo and Lu Shaowu were not allowed to have access to the radio station's core secrets due to their identities, so they were arranged to become maintenance personnel. Zhou Mo was unwilling to do so.

In July 1932, the Kuomintang officially launched the fourth encirclement and suppression campaign with the Hubei-Henan-Anhui Soviet Area as the main target. This time the Kuomintang deployed 24 divisions around Hubei-Henan-Anhui Province with more than 300,000 troops and four aviation squadrons.Xinji, the capital of the Hubei-Henan-Anhui Soviet Area, was constantly bombarded. The Fourth Red Army retreated westward as a whole, and the radio station was split into two. Cai Zechuan led the radio station alone.On the occasion of separation, Cai Zejuan handed over the secret code book to Xu Xiangdong and Qu Zhengye to obtain more enemy intelligence.

During the transfer, there was a problem with the radio station. Zhou Mo helped repair it and quickly restored the radio station to normal use.Zhou Mo missed his lover Tao Ge and unconsciously tapped the tiger with his fingers, which attracted Shi Lanqing's attention.On the other side, Dane took the initiative to come to Huang Jibi and said that he was currently serving as the director of the Intelligence Division. Many people were eyeing the Interpretation and Interpretation Institute and were willing to cooperate with Huang Jibi for mutual benefit.

Cai Zejuan, Xu Zhengye and others marched separately, climbing mountains and crossing rivers, and traveled long distances.Because the radio station was in urgent need of manpower for reporting, Shi Lanqing, Du Hong, and Wang Xiaojing took over temporarily and worked hard to copy the radio content.Cai Zejuan asked Zhou Mo and Lu Shaowu if they remembered the Kuomintang's internal call sign frequency and told them to use this frequency to receive messages.Lu Shaowu had never done electronic translation work before, so he recommended Zhou Mo to translate.

Now that the Kuomintang is using the code designed by Huang Jibi, even Zhou Mo can't translate it.Tao Ge took the initiative to ask Huang Jibi to know whether his password adopted the classical model. Sure enough, Huang Jibi said that he did refer to Chinese classical cryptography, so the Communist Party must still follow modern Western cryptography, and it is completely impossible to decipher the content.At the same time, Xu Dapeng sent a message to Commander Wang and others on behalf of Cai Zejuan, suspecting that the enemy was making large-scale mobilizations, and there was likely to be a large-scale military operation soon.
