A call from the Third Bureau urgently instructed the troops belonging to Red Fourth to immediately change direction, go south to join the left army, and cross the grassland again.Facing this order, Cai Zejiu had no choice but to lead his troops back.On the way, when they saw the remains of the fallen soldiers, everyone took off their hats to pay tribute, and their hearts were filled with sorrow. A funeral was held for the martyrs. At the same time, Cai Zejiu became deeply confused about the bright future that he once believed in.

During this difficult march, Cai Zejiu developed a high fever due to overexertion and the invasion of wind and cold.Upon seeing this, Li Guodong decisively ordered him to suspend all work and wait for treatment after leaving the grassland.As night falls, Lu Shaowu accompanies Cai Zejuan, giving him a firm belief that the darkness will eventually pass and dawn will come.

On the other hand, Zhang Guotao believed that the Central Red Army's move northward could no longer shoulder the important task of leading the national revolution, and the prestige of the Central Red Army had dropped significantly among the Red Army ranks.Therefore, he quickly announced the establishment of the Provisional Central Committee and openly raised the banner of separatism.Encouraged by the Red Fourth Front Army's initial victory in the southward campaign, Zhang Guotao further strengthened his determination to break away from the Party Central Committee and insist on going south, but he did not realize that this wrong line was leading the Red Fourth Front Army into a huge crisis.

After the Fourth Red Army assembled in Zhuokeji, they once again embarked on the journey south, crossing the Jiajin Mountains where conditions were extremely harsh.A blizzard raged, signal poles were knocked down by strong winds, and radio signals were intermittent.Liu Yongzhong unfortunately died in the severe cold in order to keep communications open. However, the messages he sent with his life revealed Liu Xiang's detailed deployment of the Sichuan Army and provided key intelligence for the Fourth Red Army's southward operations.

Subsequently, the second and third bureaus met, and Xu Zhengye conveyed to Cai Zejuan the decision of the headquarters: after occupying Lushan County, they would launch an attack on Mingshan and Qionglai, with the intention of seizing the Western Sichuan Plain.However, Cai Zejuan expressed strong dissatisfaction with this decision, believing that this move was too risky and might cause the troops to be surrounded by Liu Xiang and the Sichuan army and pay a heavy price.Despite his objections, Cai Zechuan had to continue organizing intelligence monitoring work. The team stood firm in grief and provided key information to the front line.

Unfortunately, the Fourth Red Army was attacked from three sides on the plains of western Sichuan, and the two main regiments were completely wiped out. Wang Zhensheng was filled with grief and anger.Although the general headquarters ordered the evacuation of Baizhang Pass, the policy of going south has not changed.In the heavy snow of cold winter, the soldiers moved forward with heavy loads, exhausted both physically and mentally.

Fortunately, Xu Zhengye brought the news that the Communist International would intervene to resolve the differences between Red 1 and Red 4, and emphasized the importance of the anti-Japanese national united front, which gave Cai Zechuan and others a glimmer of comfort.Although Zhang Guotao has not yet made a clear stance, this is undoubtedly a positive signal.

However, the Kuomintang General Suppressor did not relax its pursuit of the Fourth Red Army.After staying in Baoxing for more than a month, the Fourth Red Army encountered a fierce attack by the main force of the Sichuan Army.Despite heroic resistance, they suffered heavy losses due to lack of ammunition, food and grass, and disparity in strength. They were eventually forced to evacuate Tianquan, Lushan, Baoxing and other places to find new living spaces.

At this time, the Second Bureau received a telegram stating that Zhang Guotao had been forced to cancel the Second Central Committee and that the Fourth Red Army would move north to join the Central Committee.This news melted the ice in Cai Zejuo's heart like a spring breeze and rekindled the fire of hope.However, new crises ensued: Xue Yue, Pan Wenhua and other troops were still in hot pursuit, and the Fourth Red Army was besieged in the mountains of western Sichuan.

Faced with a desperate situation, pessimism emerged among the team.Wang Xiaojing was worried about not being able to get out of trouble and was frustrated; Xu Dapeng angrily blamed division and wrong decisions for leading to the current predicament; while Dan Zeng took over as the director of the Interpretation and Interpretation Institute and appointed Tao Ge as the chief of the telecommunications unit to strengthen intelligence work..In the midst of hardships and hardships, the Fourth Front Army of the Red Army still persisted in moving forward, looking for a way out of the predicament.
