Mr. Li contacted Luo Wuqiang and told him that Lu Junnuo had been found, so the two parties began to negotiate terms. Mr. Li did not have deep feelings for Luzhu. He just wanted Luo Wuqiang to choose his camp, but Luo Wuqiang was not clear about his position. After hanging up the phone, Luo Wuqiang firmly stated to Director Lin of the New Fourth Army that Lu Junnuo's safety was a prerequisite for him to change his banner. In order to promote Luo Wuqiang's uprising, Director Lin carefully planned and decided to break the deadlock by rescuing Xiao Ruotong.
After learning the news of Xiao Ruotong's arrest, Gu Yizhong stepped forward and determined to carry out a rescue operation. He knew that the task was difficult, but he did not back down in the face of heavy guards. Gu Yizhong cleverly used Kondo Masao's doubts to fabricate the lie that Mr. Li was trying to use the army to fight against the Japanese, and exposed Zhou Zhifei's crimes of reselling military rations and driving up rice prices. Kondo Masao was shocked after hearing this and agreed to dispatch the Salt Well Team to assist Gu Yizhong in rescuing people.
Where Xiao Ruotong was imprisoned, Gu Yizhong led Japanese soldiers to intervene forcefully, but was blocked by Mr. Li. The female agent tried to prevent Xiao Ruotong from leaving, but she had to give in due to Gu Yizhong's determination and the intimidation of the Japanese soldiers. However, just when they were about to succeed, Zhou Zhifei suddenly appeared and blocked their way, making the situation complicated and tense again.
Facing Zhou Zhifei's threats and provocations, Gu Yizhong remained unmoved. He firmly told Zhou Zhifei that this was Kondo Masao's order, and then left resolutely with Xiao Ruotong. However, there was a fatal crisis hidden outside the door. A sniper's gunfire suddenly rang out, and Xiao Ruotong was unfortunately shot. At the last moment of her life, she held the letter tightly and asked Gu Yizhong to deliver it to Luo Wuqiang.
When Gu Yizhong returned home, Haimo asked him if he had found any trace of Xiao Ruotong. When Haimo learned that Xiao Ruotong had died, she was very sad. She did not disturb Gu Yizhong, but stood alone outside the door, looking at the sky and crying silently. Gu Yizhong locked himself in the room, thinking about what happened with Xiao Ruotong in the past, feeling very sad.
Luo Wuqiang waited anxiously in the office. Director Lin brought the news of Lu Junnuo's sacrifice and the letter left by Xiao Ruotong. After reading the letter, Luo Wuqiang was deeply shocked, confirmed Xiao Ruotong's New Fourth Army identity, and decided to follow her last wish and lead his troops to join the New Fourth Army.
Meanwhile, Gao Hu chooses to stay, while Lu Zhu is eager to return to Suzhou. Luo Wuqiang arranged for people to escort Lvzhu, but unfortunately, Lvzhu returned to Suzhou and found that her home had been occupied by Mrs. Li. She tried to escape, but unfortunately fell into the hands of the other party. In order to seek justice for Xiao Ruotong, Gu Yizhong carefully planned and used the power of the salt well to capture Zhou Zhifei's brother-in-law Ji Yuping. Ji Yuping was vulnerable and easily confessed Zhou Zhifei's crime of selling military rations and medicines. Yanjing quickly reported to Kondo Masao, who was furious after hearing the news and immediately ordered the arrest of Zhou Zhifei.
Zhou Zhifei had a premonition that a disaster was coming, and hurriedly asked his wife Yuqing to pack valuables and prepare to escape. However, their plan failed. Yan Jing led his team to break in and escort Zhou Zhifei to the torture room.
In the torture room, Zhou Zhifei tried to exchange the secret of "Gu Zhou" for the freedom of himself and his wife. He revealed to Masao Kondo that Wang Mingzhong was the superior of "Guzhou" and hinted that if there was a specific collection of poems hidden in Gu Yizhong's home, it was most likely "Guzhou" himself. After hearing this, Masao Kondo's eyes flashed with a hint of cunning, and he seemed to be very interested in this clue.
