Mrs. Guan brought new clues to Yu Chunyang. Guan Yongshan has been dismissed because of Yu Chunyang. It stands to reason that this matter has nothing to do with him, but Mrs. Guan wants to atone for him. Mrs. Guan was always sad about the new moon, but it was not easy for her to survive as a woman in this world. After all, Guan Yongshan was her family. After Mrs. Guan said goodbye to Yu Chunyang, Yu Chunyang went to the nearest phone booth, but he didn't make a call, so he asked a kid selling newspapers on the street to deliver things for him. Yu Chunyang pretended to be an electrician and came to Daxigou Power Plant to find Captain Zhou. Xie Dongdong and Wu Ruonan were in charge of this matter. Before the operation started, Wu Ruonan accepted Xie Dongdong's engagement ring for the first time.
Captain Zhou was the only one left in the factory, and a lot of spies were hiding there. Yu Chunyang told him that 20 tons of explosives were hidden in the factory. Soon the two confirmed the authenticity of this incident. If the explosives exploded, the surrounding area would be razed to the ground. Xie Dongdong and Wu Ruonan brought some power tubes to detonate. Seeing this, Yu Chunyang and Captain Zhou decided to destroy these things and sabotage their plan. At the same time, Chen Qian received a note asking him to meet at the power plant.
Yu Chunyang and Captain Zhou were inspected when they went out, so they could only temporarily hide the power tube. Yu Chunyang was taken to work, but Wu Ruonan recognized his identity at a glance. Wu Ruonan found out that she stole the detonator. The thing is that Yu Chunyang was not killed in front of Chen Qian. Before Wu Ruonan could do anything, Captain Zhou drove over to rescue Yu Chunyang. Unwillingly, Wu Ruonan and Xie Dong chased after them and successfully forced them to stop. Chen Qian reappeared and rescued the two, but Xie Dongdong still clung to it. Xie Dongdong realized that the detonator must still be in the factory, but Wu Ruonan didn't seem to care, and just wanted to kill Chen Qian and Yu Chunyang. Facing them, Chen Qian and Yu Chunyang ordered Captain Zhou to go first, and he had to wait for Secretary Ji's support. After Captain Zhou fled, Chen Qian and Yu Chunyang raised their hands and surrendered. The two were arrested and asked about the whereabouts of the detonator. Wu Ruonan will never be soft on Yu Chunyang because he is Chen Qian's little lover. Chen Qian let them release Yu Chunyang and told them the whereabouts of the detonator, and he could give everything for Yu Chunyang. Wu Ruonan hit Chen Qian angrily, but still decided to let him take him to find the detonator.
Chen Qian led them to the cooling tower and said that the detonator was on top. In the car, Chen Qian and Yu Chunyang had already discussed the countermeasures. At this time, they had already quietly cut the rope with a blade. While they were looking for the detonator, Yu Chunyang and Chen Qian were about to escape, but Xie Dong shot Chen Qian, Yu Chunyang escaped smoothly, Wu Ruonan stepped on Chen Qian in confusion, and expressed dissatisfaction with Xie Dong's shooting. Xie Dong asked her to shoot and kill Chen Qian, but Wu Ruonan couldn't let Chen Qian go from the beginning to the end. Xie Dong was furious and wanted to kill Chen Qian, but he didn't expect that at this moment, Wu Ruonan shot him in the chest.
Xie Dongdong's men found the detonator, and Yu Chunyang also arrived at the radio room smoothly, encouraging the workers to protect the detonator. Wu Ruonan finds it ridiculous that Chen Qian is using her. She is wishful thinking, but Chen Qian is always so unfeeling to her. Wu Ruonan was reluctant to kill him, so he knocked him out and went to kill his favorite person. The workers shouted the slogan of defending Chongqing, and the Kuomintang shot and killed people. Fortunately, Secretary Ji arrived in time with reinforcements. At the same time, Wu Ruonan also came to the radio room. She couldn't stop the decline of the Kuomintang, but she didn't want Yu Chunyang to live to see everything she wanted. Wu Ruonan said that he killed Chen Qian, and also shot Yu Chunyang.
After the People's Liberation Army entered Chongqing, Chongqing ushered in liberation. Spring of 1951. Chen Qian received the news that the other side sent someone to carry out a secret mission, and it was said that they were Guan Yongshan's subordinates. For such a long time, Yu Chunyang has been sleeping deeply, and Chen Qian always tells her the latest stories. He arrested Guan Yongshan, but Wu Ruonan took advantage of the chaos and escaped at the power plant that day. After the liberation of Chongqing, the anti-traves situation is still arduous, and the tasks of Chen Qian and others are equally arduous and have a long way to go.
