Soon, Wang Zhensheng and others discovered that an enemy was approaching, so they sent Xu Dapeng and Lei Shen to escort the people of Ertai, but they were surrounded by enemies.Cai Zejuan ordered everyone to bury the equipment on the spot as a precaution. Commander Cai Zejuan was shot and died while covering the departure of the two station personnel. Cai Zejuan fell into deep self-blame. He studied code deciphering day and night, but still had no idea.

Shi Lanqing reported the incident to Li Guodong, saying that Cai Zejuan blamed himself for the combat losses and the death of Commander Cai. He always felt that his intelligence work was not done well, and others were worried about Cai Zejuan's health.Li Guodong was very pleased that the two stations were so united, so he conveyed the instructions of the commander. In order to protect the safety of all members of the two stations, they will be allowed to walk among the troops during the march in the future. The soldiers of the guard company are responsible for protecting their safety, and all equipment and baggage will be handled by the transportation team..

Not long after, the large army arrived at Huangchaifan, north of the river mouth.In the evening, Zhou Mo told Lu Shaowu that they were like bats in a flock of birds in the Red Army. However, Lu Shaowu didn't think so. He hoped that Zhou Mo could understand that they were both staunch Red Army soldiers now and should give up swinging.Uncertain thoughts.

Early the next morning, Cai Zejuan asked Lu Shaowu and Zhou Mo whether they had been exposed to work related to the Kuomintang radio code.Zhou Mo bluntly said that the Kuomintang invited cryptography expert Huang Jibi from abroad to design the password, shared Huang Jibi's mathematical encryption ideas, and suggested that Cai Zechuan should start with Huang Jibi.Cai Zejuan realized that Zhou Mo was too smart and was still worried about her, so he did not leave the radio-related matters to her. On the other hand, Huang Jibi asked Tao Ge to work with him to decipher the Red Army code.

Xu Zhengye brought the next step of action instructions and conveyed that the Hubei-Henan-Anhui Central Branch and the Fourth Red Army Command held an emergency meeting and decided to abandon the Hubei-Henan-Anhui Soviet Area and arrange for other troops to jump out of the enemy siege and go to the west of Pinghan Road to find the Red Army.Because it was top secret, in order to prevent leaks, Xu Zhengye informed them to leave early tomorrow morning.

However, Cai Zejuan did not have optimistic thoughts. He had lost contact with the radio station in the Western Soviet Area of ​​Hunan and Hubei for a long time, and he was afraid that something bad would happen.As Cai Zechuan expected, when everyone arrived at the garrison of the Red Army, they found that the Red Army had already evacuated and still failed to successfully join forces.At this moment, a call came from the main station informing the large forces that they would return to the Hubei-Henan-Anhui base area.

Dane was ordered by the commission to come to Huang Jibi and inform him that the Kuomintang intended to encircle and annihilate the Fourth Red Army. He hoped that Huang Jibi would encrypt the secret message and send it to various ministries.The Central Red Army State worked hard to decipher the secret report. After learning about it, Army Commander Wang Zhensheng ordered his troops to assemble urgently and march to the Nanhuatang area.

Because of this, Dane once again came to urge Huang Jibi to decipher the CCP's secret message as soon as possible.Huang Jibi repeatedly emphasized that he only worked in secret communications and did not understand their so-called political struggle at all.At this moment, the Fourth Red Army, with the intelligence support of the Second Bureau of the Central Revolutionary Military Commission, immediately turned around and headed west. After five days of rapid march, the entire army entered the Xichuan area at the junction of Henan and Hubei through the Shahe and Xianghua highways, and got rid of the 400,000-strong Kuomintang army in Xiangzaoyi.However, the Fourth Red Army also lost the conditions to fight back to the Hubei, Henan and Anhui base areas and was forced to find a new foothold.

Cai, Xu, and Qu worked together again. Inspired by the country's meritorious service, the three were determined to decipher the enemy's electricity.Cai Zejiu intercepted the enemy's telegram again and found that the code had been changed. The three of them tried to decipher it again.After intercepting the message for the second time, Cai Zejuan's heart sank. He was worried that the previously deciphered message was a mistake, and that Commander Cai's sacrifice would happen again.

Wang Ying, who works at the translation office, wants to drive a wedge between Tao Ge and Huang Jibi, but Tao Ge is loyal to Huang Jibi.The Kuomintang troops moved along the road and were only ten miles away from Nanhuatang. Enemies were also found in other places. Wang Zhensheng made emergency deployments to deal with the enemy encirclement. With the sound of gunfire so close, Cai Zechu regretted not being able to provide more for the Fourth Red Army.Valuable information.

Superiors instructed the Fourth Red Army to quickly abandon Nanhua Sugar in order to retain their strength.Lei Shen was ordered to cover the safe evacuation of the radio station personnel, but found the enemy halfway, so he had to let Xu Dapeng lead the people to escape first, and they were responsible for covering.Because several elite units of the Kuomintang encircled and attacked, the Fourth Red Army was attacked from both sides and faced many dangers.
