There was heavy artillery fire outside the camp, and the Battle of Jianmen Pass started again. Cai Zejiu received a telegram and learned that the battle of Jianmen Pass was not going well. The defenders were well-equipped, and the Red Army had failed to charge several times. The battle had already killed a regiment of the 31st Red Army.The troops were lost, so the front line asked the two stations to closely monitor the enemy's radio waves to prevent the enemy from tailing them.

Zhou Mo stayed in the camp and missed Tao Ge, and asked Du Hong how to apply to join the party, planning to reunite with Tao Ge after gaining the trust of the Central Committee.Yongzhong caught fish in the river and asked the cooking team to make some fish soup and serve it to Cai Zejue. However, Cai Zejue felt that he could not eat alone, so he decided to call everyone in Ertai and let everyone appease their appetite.

Dane once took the initiative to come to Huang Jibi and questioned him angrily. He also used the Fourth Red Army to secretly cross the Jialing River to stimulate Huang Jibi, saying that the party-state's troop deployment had been informed by the Central Government and that they had changed direction at the end of the road.Huang Jibi had no idea that the Chinese government, with so many talented people, could decipher his own code in a short period of time, and was greatly shocked.

Zhou Mo took advantage of the opportunity to be on duty alone, adjusted the call sign and frequency band, and contacted Tao Ge in time, which made Tao Ge overjoyed.Seeing this, Lu Shaowu went over to change shifts with Zhou Mo, saying that the duty was to let everyone take turns to rest. Zhou Mo could not refuse, so he had to leave first. As a result, Lu Shaowu discovered something strange.

After Tao Ge confirmed that Zhou Mo had become a prisoner, he was very excited and hurriedly told Huang Jibi about the incident. He also had a plan in mind, that is, they could not decipher Zhonggong's code for a long time, so they simply used Zhou Mo's convenience to ask her to helpGet the Chinese password book and even the key.Only in this way, Zhou Mo became an undercover agent arranged by Huang Jibi in the Central Government, and returned to the party state after meritorious service.

Lu Shaowu thought about it and decided to report Zhou Mo's situation to Cai Zejuan, saying that Zhou Mo was sitting alone in front of the radio station and did not send a report.Cai Zejuan told Lu Shaowu not to doubt his comrades without evidence. This would not be conducive to unity, so he asked him to go back and rest without telling anyone.Early the next morning, Zhou Mo came to Cai Zejuan to apply for party membership, and Cai Zejuan promised to submit her application to the party branch for discussion.

For three consecutive days and nights, Jianmen Pass was still unbroken. Commander-in-Chief Xu sent troops to support, and the Fourth Red Army would launch a general attack at Jianmen Pass.In the end, Deng Xihou could not withstand the attack, and the Fourth Red Army successfully broke through Jianmen Pass. Everyone was extremely surprised, except Zhou Mo who couldn't believe it and found it incredible.

In March 1935, the Fourth Red Army broke through Jianmen Pass and began the Long March.Cai Zejuan and his teammates from the Second Station, carrying heavy telecommunications equipment, embarked on a long journey with the 31st Army, the main force of the Red Fourth Front Army.When Shi Lanqing saw an abandoned baby in his new station, he had no choice but to take it back first. Cai Zechuo thought of the son he had never met, so he asked the lesbians to take turns taking care of him to see if they could find someone to adopt him.At the same time, Xue Pinxuan personally taught her son to read and read, cultivating him to have patriotic feelings like Cai Zechuan.

The radio station was suddenly damaged. Zhou Mo proposed to take it back to his room for inspection, but Cai Zejuan did not agree. Instead, he took it back to the room for repairs and arranged for Lu Shaowu to adjust the frequency for monitoring.Cai Zeju then reported the situation to Wang Zhensheng and Li Guodong. Li Guodong gave Cai Zeju a novel, and he used the novel to pretend to be a codebook to test Zhou Mo.Sure enough, Zhou Mo believed it was true and prepared to contact Tao Ge.When Cai Zecheng told Du Hong to be on duty, he deliberately gave Zhou Mo the opportunity to be on duty alone.That night, Tao Ge took the initiative to send a telegram to Zhou Mo, and Zhou Mo also monitored the contents of the telegram.
