Due to Cai Zejuo's deliberate arrangement, Zhou Mo sneaked into his workshop under the pretense of going to the bathroom. After searching around, he found the book - Wanping Bells.She speculated that the person who could carry such a popular leisure book with him was probably an emissary of the Red Army and carried an important key.However, Zhou Mo did not realize that he had been exposed to Cai Zehuo's surveillance and was stepping into a trap step by step.When she returned to the radio station, she found that all her colleagues had left, leaving Du Hong alone.

Zhou Mo asked Du Hong to go to the cooking class to get some food for her on the pretext of being hungry.After Du Hong left, she impatiently sent the book disguised as a code - Wanping Bell - to Tao Ge.Unexpectedly, everyone suddenly appeared in the next second, and Zhou Mo was arrested on the spot, with both the person and the stolen goods.Although she tried her best to deny it and insisted that she was just delivering information for her family, Lu Shaowu's surveillance records ruthlessly exposed her lies.

Facing the truth that was about to be revealed, Zhou Mo desperately mentioned her contribution to the Red Army and begged everyone to be kind and let her live.Cai Zejuan also felt heavy in his heart, but he knew the serious nature of the matter, so he decided to leave everything to the military for decision and ordered Zhou Mo to be taken away.Shi Lanqing was deeply saddened by this, but Cai Zechuan understood. He knew that if Zhou Mo had not gone astray, he would be both a teacher and a friend to Shi Lanqing, and sadness would be inevitable.

Tao Ge, who received the telegram, firmly believed that the Wanping bell was the key to deciphering the code and immediately reported it to Huang Jibi.He firmly believed that this was a message sent by Zhou Mo with his life, and it must be deciphered as soon as possible.Although Huang Jibi felt embarrassed, he still agreed to try.Tao Ge immediately ordered Wang Ying to search for the book, but learned that he needed to collect all versions of Wanping Bells before he could succeed, and the task was arduous.

At the same time, Xu Dapeng successfully found an adoptive family for the child, and Cai Zejuan personally named the child Liu Dianbo at the suggestion of Shi Lanqing and others.The Cai family has been searching for Cai Zejiao for many years without success. Cai Zhisheng misunderstood his father as a villain because he saw Xue Pinxuan crying while reading the letter, and became dissatisfied because of his lack of father's love.Cai's mother was even heartbroken after hearing the news.

Zhou Mo's departure made the atmosphere at Radio 2 become dull and depressing, and all colleagues who had friendship with her felt sad.Lu Shaowu felt deeply sorry for Zhou Mo's experience.However, bad news came one after another - Xu Dapeng reported that Zhou Mo jumped off a cliff and died during the escort.Cai Zejuan requested punishment from Wang Zhensheng and Li Guodong, but was only criticized internally.

Lu Shaowu fell into deep self-blame because of this. Thanks to Cai Zechuan's enlightenment and comfort, his mood gradually improved.He plucked up the courage to express his desire to join the party to Cai Zejuan, which made Cai Zejuan very happy.Seeing that Lu Shaowu worked hard and performed well, Cai Zejiu believed that he sincerely wanted to stay in the Red Army, so he encouraged him to write an application for joining the party.

On the other side, Huang Jibi and Tao Ge's work on deciphering the Wanping Bells was progressing slowly and anxiously.Dan Zeng finally found various versions of the Wanping Bell and revealed that the party-state had mobilized ten mathematical elites to form an encryption team to assist in the deciphering work.However, Tao Ge lost control because he never received a call back from Zhou Mo and resorted to drinking to drown his sorrows.

Pan Qingqing questioned Huang Jibi's motif theory, believing that if one could grasp the motif of the party-state, one could easily decipher all its encrypted information.This view aroused Huang Jibi's interest and triggered his in-depth thinking.Tao Ge became even more furious after seeing Huang Jibi unable to attack for a long time and even planned an internal struggle.Huang Jibi was surprised to find that Tao Ge seemed to be no longer the person he was familiar with.

At the same time, Cai Zechuan also emphasized the importance of discipline within Radio 2 to prevent incidents like Zhou Mo from happening again.As the enemy's codes are constantly updated, the difficulty of deciphering them is also increasing.In order to meet this challenge, Cai Zejuan decided to let Lu Shaowu and Shi Lanqing join in the deciphering work.Although the two felt anxious and uneasy, they gradually mastered the deciphering skills under Cai Zechuo's careful guidance.
