Pang Hongmei and Chen Dongsheng followed the wires to find the spy. It was the dormitory building for the employees of the instrument factory. They investigated carefully. Lai Guangrun hid in the room and listened. From the window, he saw Pang Hongmei and Chen Dongsheng searching there immediately. He tore down the meeting minutes and hid behind the sack downstairs. In panic, he dropped the pen on the ground. It was too late for him to go back and pick it up. .
Pang Hongmei and Chen Dongsheng acted separately. Pang Hongmei suddenly saw the pen on the ground and guessed that the spy was nearby. Lai Guangrun saw Pang Hongmei approaching a little bit. Worried about exposing his identity, he pushed the hidden sack onto Pang Hongmei. Pang Hongmei's leg was injured. , Lai Guangrun escaped unprepared and hid in the sewer. Chen Dongsheng and the police officers arrived later, but they could not find Lai Guangrun, so they had to temporarily withdraw the team.
Ji Danyang tested the captured monitoring equipment and deliberately sneered at Pang Hongmei. Pang Hongmei could hear clearly through the monitoring earphones, and she was speechless with anger. Li Guangming handed over the files of the 108 newly hired employees, and Chen Dongsheng asked the police officers to check them one by one.
Ji Danyang learned from Chen Dongsheng that Niu Peixian was an eighth-level craftsman in the shipyard, so he came to him to process the parts. Niu Peixian promised to make them within half a month. During lunch, Ji Danyang took out the powder of the red gold stone bracelet and showed it to Chen Dongsheng. Pang Hongmei learned that her bracelet had been crushed into powder. She was very angry and complained that Ji Danyang did not tell her in advance. Ji Danyang promised to give her an identical one. Bracelet, Pang Hongmei was relieved a little.
Ding Jie found out from the railway department that Nian Fufu often traveled between Guangzhou and Lumen to do the pepper business. He reported the matter to Chen Dongsheng, who asked him to keep an eye on Nian Fufu. Li Guangming received a letter from his girlfriend Qianqian who was far away in Hong Kong. Qianqian expressed his longing for her in the letter. Li Guangming had mixed feelings in his heart, so he hid the letter in the hole in the wall behind the mirror.
Ji Danyang called Bai Hui and invited Bai Hui to go to Rhinoceros Horn to look for red gold stones tomorrow afternoon. Bai Hui agreed wholeheartedly. Luo Shanshan and the nurses were all envious of Bai Hui. Lai Guangrun came to negotiate with Bai Minghan and asked him to come out and participate in Operation Rock. Bai Minghan flatly refused, and Lai Guangrun threatened Bai Hui's life.
Bai Hui and Bai Minghan asked for leave in the afternoon to accompany Danyang to Rhinoceros Horn. Lai Guangrun claimed that he was familiar with the terrain there. Bai Minghan was worried that he was plotting against Bai Hui and warned him not to act rashly. Bai Hui dressed up beautifully and went out. Bai Minghan asked her to deliver medicine to three clients on the pretext of going on a medical visit. Bai Hui was worried that she wouldn't have enough time, but she couldn't resist Bai Minghan, so she had to do it.
Pang Hongmei had something to do and asked Ding Jie to accompany Ji Danyang and Bai Hui to Dongshan. Ding Jie drove to pick up Ji Danyang, but Bai Hui didn't arrive. Ji Danyang asked the guard to inform Bai Hui to go directly to Dongshan to meet them. Bai Minghan went to Dongshan to collect medicine, and saw Lai Guangrun from a distance. Lai Guangrun persuaded him to come out of the mountain. Bai Minghan asked Xue Lang to come to him in person, and Lai Guangrun asked him to kill Ji Danyang as a pledge of surrender.
Bai Hui delivered medicine to Uncle Fu, and Uncle Fu agreed to help deliver the two doses of medicine. Bai Hui hurriedly went to find Ji Danyang. Ji Danyang led Ding Jie up the rhinoceros horn and saw a lot of red gold stones under the cliff. Ding Jie followed the vines to the bottom of the cliff. Lai Guangrun took the opportunity to knock Ji Danyang unconscious and forced Bai Minghan to kill Ji Danyang with an art knife. Bai Minghan refused to do it. Lai Guangrun drew his gun at him. Bai Minghan asked him to create the illusion of accidental death, otherwise they would not survive.
Bai Hui walked halfway up the mountain and met Lao Huo who was returning from cutting firewood. She learned from him that her father Bai Minghan had also come to Dongshan, so she didn't think much about it. Bai Hui walked halfway when she suddenly saw a person rolling down the cliff. She ran over and found that it was Ji Danyang and Ji Danyang who rolled down. Ji Danyang was unconscious due to excessive blood loss. Bai Hui hurried down the mountain to stop the car on the road.
Ding Jie climbed up from the cliff and found a pool of blood on the edge of the cliff. Ji Danyang was missing, so he hurried to find someone. Zhang Yan sent Lao Jiang to the school to find the suspect among the qualified teachers. Soon, Hao Dongyang and Lai Changqing, who had been art teachers before liberation, were missing. Zhang Yan asked Lao Jiang to start the investigation from their acquaintances. .
