Pang Hongmei did not know that Bai Minghan had concealed the fact that Pang Shizhao was a Communist Party member lurking in the Kuomintang.Bai Minghan once treated Pang Shizhao and handed him a key before his death. The key pointed to where the evidence of Xue Lang's crime was stored.Bai Minghan found the key from the hole in the wall.

Lin Ranhai killed Li Qiuchen and pretended to be him and came to Lumen, hoping to see his cousin Li Peizhang as soon as possible.Zhang Yan arranged for Pang Hongmei to arrange this matter.When Bai Hui and Luo Shanshan came home from get off work, they saw Li Qiuchen who was accidentally injured while repairing his car, so they took him to Bozha, the factory hospital.After Chen Dongsheng confirmed Li Qiuchen's identity, he let them in.Pang Hongmei brought Li Peizhang to the hotel to find Li Qiuchen, but learned that he had gone to Dongfang Farm.Ge Yun personally sutured Li Qiuchen's wounds.

Pang Hongmei and Li Peizhang came to the hospital, and they finally reunited after a long separation.Ge Yun asked them to go to the conference room to reminisce about the past, while Pang Hongmei watched coldly from the side, carefully observing Li Qiuchen's every move.Li Peizhang took Li Qiuchen to visit the factory and introduced him to Ji Danyang.Li Qiuchen and Ji Danyang both studied abroad, so they had many common topics, and the more they talked, the happier they became.Pang Hongmei didn't notice anything unusual about Li Qiuchen, but she didn't dare to let down her guard at all.

Bai Hui came to the office to measure Han Yundong's blood pressure, and Lu Cheng happened to come to deliver documents to Han Yundong.Han Yundong left in a hurry after receiving a call from the workshop director.Lu Cheng invited Bai Hui to watch a movie together. Bai Hui readily agreed and encouraged Lu Cheng to work hard, believing that he would become the director of the factory sooner or later.Bai Hui accidentally saw a piece of titanium stone placed on Han Yundong's table. Out of curiosity, she picked it up and looked at it.Lu Cheng approached Bai Hui, and their shadows were projected on the titanium stone.Bai Hui asked Lu Cheng to keep the stone well, and Lu Cheng gave it to Bai Hui on the spot as a souvenir.

Lu Cheng came to the expert group in the name of soliciting everyone's opinions on the factory office work, but Li Peizhang and others were not interested.Lu Cheng secretly took away a piece of titanium stone when they were not prepared.Li Qiuchen visited around Lumen and took a lot of photos. Pang Hongmei followed him secretly, but was discovered by Li Qiuchen.Li Qiuchen took a photo of Pang Hongmei and invited her to have dinner with her in the evening, but Pang Hongmei politely declined.

Then, Li Qiuchen came to the tailor shop to make joints, and Miao Huilan took him into the secret room.Li Qiuchen affirmed Miao Huilan's latent work and asked her to deliver a gift to Feihu and an important task to Feihu.Chu Huaiqiu approached Han Yundong and Zhang Yan to discuss setting up a base for survival experiments and showed them the drawings.However, Zhang Yan was worried about leaking secrets and did not allow Lu Cheng to record.Xue Lang called Kou Xuesong and reported to him Li Qiuchen's situation. Kou Xuesong asked him to follow Li Qiuchen's orders.

Li Qiuchen went to Bai Minghan to seek medical advice, and Bai Hui took him home.Li Qiuchen used code words to communicate with Bai Minghan, but Bai Minghan pretended not to understand.Li Qiuchen thanked Bai Minghan for treating his father and tried to show his kindness to Bai Minghan, but Bai Minghan did not appreciate it, so Li Qiuchen had to leave in frustration.Bai Minghan reminded Bai Hui to stay away from Li Qiuchen, but Bai Hui was unconvinced and insisted that Li Qiuchen was a patriotic overseas Chinese.Bai Minghan resolutely did not allow her to have any contact with Li Qiuchen.Wu Rui suddenly had a nosebleed while working in the workshop. The workers rushed him to the hospital, and Bai Hui helped him treat the wound.After get off work, Bai Hui went straight to the tailor shop, and Miao Huilan took out the items that Li Qiuchen gave her.
