Under Cai Likun's teaching and development, Ali finally sworn into the party and quickly learned the Morse code. The first task he accepted was to send a telegram to the post office. Because the informant died tragically because of Niu Er and Wu Tanmu, and worried about his personal safety, Xue Ning simply comforted him and paid him away.
Nakamura found out that many opium was exposed on the market, and many people died from overdose of opium. Ding Siye insisted on denying that this matter had anything to do with him. In fact, Nakamura didn't care. He only wanted to smuggle and sell heroin through Ding Siye's channels. Ding Siye thinks that selling heroines is too risky and hesitates. Ma Tianming hides by the door and overhears the conversation between the two. He has already made a small calculation in his heart. He immediately went to Ding Siye and said that he had a way to reduce the toxicity of the smoke soil.
Ma Tianming continued to take care of Zhu Tiande, but when he turned over, he accidentally knocked off his breathing tube, causing Zhu Tiande to die. Fortunately, Bai Julie heard the alarm and rushed to Zhu Tiande in time to rescue her, which turned the crisis into peace. Bai Zhuli couldn't help but blame Ma Tianming, and even applied to Dean Su to treat Zhu Tiande with him.
Tao Chengkai approached Xue Ning and took the initiative to mention the recent death of opium. Because the incident was so extensive, he wanted to persuade Xue Ning to put aside his past grievances for the time being and join him in investigating the Japanese drug trafficking. That night, Ma Tianming dreamed that he was going to take his younger brother away and was discovered by Ding Siye. In the end, the two died under the gun.
At this time, Dean Su suddenly ran to inform Ma Tianming to go out to the emergency room. At first, Ma Tianming refused for various reasons, but it seemed that the situation was very urgent, so I couldn't evade it. As a driver, Cai Likun sent Ma Tianming to a designated place, only to find that the car was getting more and more remote, and soon came to the outskirts.
The quarantine area was heavily guarded and everyone was wearing protective clothing. Under Tao Chengkai’s introduction, Ma Tianming learned that the Japanese had established a laboratory in the Northeast on the grounds of purifying water. However, they found that Chinese prisoners were often sent there, and there were still some. There is no return. In order to investigate the truth, the Kuomintang lieutenant took the initiative to ask Ying to enter the laboratory disguised as an ordinary citizen, but did not want to find that the other party was doing a bacterial experiment.
Later, the lieutenant ran away from the laboratory. He did not expect to have a high fever as soon as he returned to Shanghai. Now the whole family will be coming from all over the world. Cai Likun believes that the lieutenant is an infectious bacteria that causes fever. It should be the Japanese who are preparing for the germ warfare. They must get the serum as soon as possible before they can enter the study. Otherwise, the three million people in Shanghai are at stake.
Ma Tianming didn't want to be infected with these things. What if they couldn't work out a treatment, but Cai Likun asked him if the infected were Ali, Xiaosi, Bai Julie and Zhang Nana, would he still think so. After Tao Chengkai came back, he said that he knew "Cai Likun" had experience in participating in infectious diseases, so he was brought in. Now the expert can only rely on Cai Likun for help because of the weather.
Cai Likun suddenly wanted to enter the quarantine area to test the patient's condition in place of Ma Tianming, and then Ma Tianming would provide remote guidance over the phone. Facing Tao Chengkai’s doubts, Cai Likun explained that he had worked in a plantation and had a basis for injections and experiments. Ma Tianming also promised that Cai Likun had the ability, and Tao Chengkai had to agree.
Before parting, Cai Likun confessed that if he couldn't get out, he would ask Ma Tianming to continue to complete Zhu Tiande and the fund. Ma Tianming hugged Cai Likun tightly and told him to come back safely, even for his wife and children abroad.
