Zhang Ashui refused to explain anything and fantasized about relying on the information he had to get his superiors to send people to rescue him. Zhang Yan found out that Taiwan's intelligence agency had formulated a rock plan specifically for the Water Drop Project, and that the man behind the scenes was her old rival Kou Xuesong. . Bai Hui came to give Zhang Ah Shui an infusion, and Zhang Ah Shui recognized her as Bai Minghan's daughter. She kept claiming that Bai Minghan had saved many people, including good and bad people, and specifically asked Bai Hui to ask Bai Minghan if he knew Xu Wenzheng. Xu Wenzheng was a latent agent of the Kuomintang, codenamed "Snow Leopard", and was executed in 1953. Pang Hongmei dug up Xu Wenzheng's information and found that Bai Minghan had gone to the prison to treat Xu Wenzheng. There were no other abnormalities. Pang Hongmei still felt that Bai Minghan was suspicious. Chen Dongsheng felt that Bai Minghan was fine, otherwise he would have silenced Zhang Ashui during the treatment.
Pang Hongmei learned about the grievances between Kou Xuesong and Zhang Yan from Lao Jiang in the archives. In 1947, Zhang Yan was ordered to build a liaison station in Zhangjiakou, but it was destroyed by Kou Xuesong's agents who had been ambushing her for three years. Zhang Yan hated Kou Xuesong. It penetrates to the bone. Kou Xuesong knew that Zhang Ashui had the meeting minutes of the Water Drop Project in his hands. He was even more worried about the identities of agents such as Li Guangming and Gecko being exposed, and ordered Xue Lang to get rid of Zhang Ashui as soon as possible to ensure the safety of the agents. Kou Xuesong learned that the Chinese medicine doctor who woke up Zhang Ashui was Xu Wenzheng's agent Bai Minghan, codenamed "Ghost Owl". Kou Xuesong wanted to use Bai Minghan, but was worried that he would be incited to rebel, so Kou Xuesong sent someone to test him.
Ji Danyang received a threatening letter spelled out with words cut out from newspapers, asking him to take the information on nuclear submarines compiled by An Wenshan and go to the telephone pole outside the department store at four o'clock tomorrow, otherwise An Wenshan's life would be in danger. , Ji Danyang broke out in a cold sweat. Lai Guangrun came to Bai Minghan for a massage and casually mentioned that he brought precision instruments to the instrument factory. After Lai Guangrun left, Bai Minghan found a secret letter in the book. After Ji Danyang received the threatening letter, he was distracted every day and often made mistakes. He Xiwen thought he was too tired and advised him to go back and rest, but Ji Danyang couldn't explain clearly. Xue Lang gave Li Guangming a secret order, asking him to get rid of Zhang Ashui at 7:30 in the evening. Zhang Ashui asked Li Guangming to send a message to Xue Lang to rescue him within three days, otherwise he would explain everything.

Bai Hui came home from get off work and asked Bai Minghan about Xu Wenzheng. Bai Minghan guessed what Zhang Ashui said and advised Bai Hui not to listen to the slander. It was his bounden duty to treat illnesses and save people. He didn't care who the patient was, so Bai Hui didn't ask any more questions. Seeing that the scheduled time was coming, Ji Danyang took advantage of Pang Hongmei to go out in a hurry and asked the police officer on duty to accompany him to the construction site. Ji Danyang lied about going to the bookstore and asked the police officer to stop halfway, and Pang Hongmei followed quietly in her car. Chen Dongsheng strictly interrogated Zhang Ashui, but Zhang Ashui refused to explain who Snow Wolf and Gecko were. He was just waiting for his superiors to send someone to rescue him.
Ji Danyang came out of the bookstore, cleverly avoided the protection of the police, and came to the telephone pole outside the department store alone. Pang Hongmei then arrived and watched Ji Danyang from a distance. A child threw a paper plane at Ji Danyang's feet. Ji Danyang quickly picked it up. It said that he would be at the post office phone booth at five o'clock. Ji Danyang rushed over without saying a word. Pang Hongmei hurriedly picked it up. Then he followed him to the post office and asked the police officer who was accompanying him to find the child to understand the situation.
At five o'clock, the phone rang on time. Ji Danyang hurriedly picked it up. He hung up the phone and hurried out. Pang Hongmei asked the police officer to check where the call came from. She followed Ji Danyang to the library. Ji Danyang came from A note was pulled out of a book, and Pang Hongmei saw it all. Ji Danyang came to the riverside. He waited for a long time but no one came. Pang Hongmei hid aside and watched him. Lai Guangrun sent a batch of precision equipment to the instrument factory. He took the initiative to help the workers move it and accidentally injured his foot. Ge Yun bandaged Lai Guangrun. His foot was broken and he needed to rest for three months.
Lu Cheng tried his best to please Bai Hui and brought the new tea of that year to give to Bai Minghan, but Bai Hui politely declined. Zhang Ashui threatened to kill Bai Minghan and asked Bai Hui to tell Bai Minghan. Lai Guangrun was inconvenient due to his injured legs and feet. The nurse helped him get medicine and asked him to rest in the corridor. He saw Li Guangming walking outside the ward. Bai Hui went to measure Zhang Ah Shui's blood pressure and wanted to take the opportunity to kill him. Suddenly, the entire hospital building lost power. Bai Hui was so frightened that she hurriedly hid.
Chen Dongsheng and the police officers came after hearing the news. They sealed the hospital. When Chen Dongsheng went to the ward, he found that Zhang Ashui had been killed. He saw Bai Hui shivering behind the screen. Bai Hui heard someone entering Zhang Ashui's ward and forced Zhang Ashui to Tell where the information is hidden
