Zheng Feixiong tied up the military command agent and asked his wife to guard him with a gun. Fang Jiashu came up with a good solution for him. Zheng Feixiong went home and negotiated with the military command agent, asking him to put Zheng Xinbao back first, and install a phone in Li Lixing's secret room. The bomb, the military command agent resolutely refused to do it, and insisted that Zheng Feixiong complete the task before releasing Zheng Xinbao.
Zheng Feixiong took out a bottle of poison yew to poison the agent, but the agent threatened that he would not release Zheng Xinbao even if he died. Zheng Feixiong drank half of the bottle of poison and passed out on the spot. The agent poured it down, and the agent desperately broke free and rushed to the hospital.
Zheng Feixiong insisted on seeing Zheng Xinbao before drinking the antidote. Su Yalu had to go to Fang Jiashu to discuss it. Fang Jiashu agreed to install a phone bomb in Li Lixing's secret room. As long as Su Yalu told the real purpose of this operation, Su Yalu had to tell the truth. The oil and steel used by the Japanese army to launch the war were provided by the Americans. Once the Americans cut off the supply, the Japanese army would be unable to move forward. Li Lixing heard about a geologist named Fu Beihong. Li Lixing decided to find Fu Beihong to trick the Japanese for a new and cheap synthetic technology of coal-based oil. Once Li Lixing handed over Fu Beihong to the Japanese, it would be a devastating disaster for the resources of China and the world.
Fang Jiashu realized the seriousness of the problem after listening to Su Yalu's words. The military command used the phone to monitor Li Lixing, and then found Fu Beihong. Monitor Li Lixing's real purpose.
Zheng Feixiong refused to take the antidote, and fought with the army to the end. He was unconscious all the time. Mrs. Zheng was so anxious that Fang Jiashu and Tao Yuling brought him antidote soup. Fang Jiashu took the opportunity to install a monitoring device in the lampshade. Zheng Feixiong was willing to drink the antidote when the military command agents sent Zheng Xinbao back. He gradually came to his senses and saw that his son Zheng Xinbao was safe and sound, struggling to get up. The agents forced Zheng Feixiong to fulfill his promise.
Fang Jiashu turned on the monitoring device at the entrance of the alley. He heard the conversation between Zheng Feixiong and the agent, and immediately took the monitoring device away. Tao Yuling wanted to stop by to see Zhao Quanzhang, and the two said goodbye. Tao Yuling walked past the rice noodle shop calmly and found nothing unusual. She was just about to go in to find Zhao Quanzhang when it started to rain heavily. Tao Yuling and Zhao Quanzhang made an appointment to meet once a week, but Zhao Quanzhang didn't show up for half a month because the situation on Tang Xingru's side was complicated and Zhao Quanzhang couldn't spare time for a while. Tao Yuling reported to Zhao Quanzhang in detail that Li Lixing wanted to find Fu Beihong to threaten the Japanese, and that the military commander wanted to install a telephone bomb in Li Lixing's secret room. Zhao Quanzhang knew that the matter was of great importance and decided to report to his superiors immediately.
Fang Jiashu was waiting for Su Yalu at the gate early in the morning, and Guo Dayu was beside him, curious about what they were talking about, and was forcibly driven away by Fang Jiashu. Su Yalu hid the monitoring equipment and telephone lines behind the police dog squad, Fang Jiashu connected the telephone lines, and Zheng Feixiong replaced the handset to test. Fang Jiashu opened the manhole cover and entered the underground pipeline, while Su Yalu stood guard for him.
Fang Jiashu quickly connected the phone line to the phone, and he climbed out of the manhole cover. Su Yalu and he went back to the office arm in arm. Fang Jiashu was worried that the phone would be soaked in water, so he wanted to dig another hole to put the phone in to disguise it. Su Yalu Let him do it right away. Ye Xingcheng came to find Fang Jiashu for a meeting, Fang Jiashu was not in the office, Guo Dayu remembered that Fang Jiashu and Su Yalu were together, Ye Xingcheng sent him to find Fang Jiashu.
It was pouring rain outside, Guo Dayu searched outside, but did not find Fang Jiashu's figure, Guo Dayu went to Su Yalu to inquire, Su Yalu didn't know anything, and forced him away. Zheng Feixiong came to the office in the rain, Li Lixing saw that his face was pale, and asked him to go back and have a good rest, Zheng Feixiong had to leave first.
When Li Lixing learned that Fang Jiashu was missing, he asked Ye Xingcheng to send someone to look for him. Fang Jiashu disguised the telephone, and he came out of the well cover. Guo Dayu came to look for him in the backyard. Seeing that he was dry, he suspected that he had come out of the well cover. sewer. Even though Su Yalu came to rescue Fang Jiashu and pretended to quarrel with him, Ye Xingcheng came after hearing the news and asked Fang Jiashu to go to a meeting.
