After a detailed examination, Cai Likun found that the second lieutenant's condition was far more serious than expected, and at least he had had a fever for more than 20 hours. Ma Tianming asked Tao Chengkai to deliberately conceal the matter, but Tao Chengkai had no idea. He only knew that the ensign had a fever since last night. At first, he thought it was caused by pneumonia, but missed the best time.
As the second lieutenant died after the rescue was unsuccessful, Cai Likun called Ma Tianming and asked him to remind Tao Chengkai to burn the things that the second lieutenant had contacted, including all related contacts, to be isolated. Just as Ma Tianming was about to send someone to pick up Cai Likun, he did not expect that Cai Likun had already decided to inoculate himself with bacteria to find a solution.
Ma Tianming couldn't stop Cai Likun's solution, and felt very sad about it. He could only watch him continue to stay in the quarantine area. Tao Chengkai was curious about the true identity of "Hancheng", and Ma Tianming concealed it. Instead, he was angry that Tao Chengkai had time to study Cai Likun. It would be better to urge the experts to arrive in Shanghai as soon as possible.
After Cai Likun injected the bacteria, he was able to buy up to three days for the experts to devote himself to the research and development of the serum. When Ma Tianming returned to the hospital, he told Ali about Cai Likun, including the next task. After they asked for the password, Ali would report to the organization. Ma Tianming was sitting beside the escort bed and muttering to himself, because he knew that Cai Likun would not be able to return for the time being, and he didn't know how long he could stay, so he hoped that Zhu Tiande would quickly tell the other half of the code.
As the expert group arrived in Shanghai, their opinions were consistent with Cai Likun's inference, and it was sufficient to prove that the ensign was suffering from the highly infectious bacillus anthracis. Tao Chengkai organized a meeting with experts. Ma Tianming called Cai Likun and learned that Cai Likun was beginning to develop flu symptoms. Although he tried to extract the virus strain from the blood sample for cultivation, the results were not satisfactory. Experts did not expect that bacteria are so destructive, which makes Ma Tianming even more worried.
At the same time, the Japanese paid great attention to the KMT’s infiltration of the laboratory. Nakamura learned that Ma Tianming was out of the emergency room and guessed that it might be related to the patient who escaped from the Northeast Laboratory, so Lin Jingshan asked Lin Jingshan to continue his investigation. Lin Jingshan asked Ma Tianming to test the identity of the patient, and Ma Tianming perfunctorily.
That night, Ma Tianming and Ali came to the ward and found that Cai Likun had knocked out the complete code. The two immediately recorded it. They didn't expect to be stopped by Tao Chengkai as soon as they walked out of the gate. Tao Chengkai already knew the identities of Cai Likun and Ma Tianming, so he asked Ma Tianming to hand over the code. However, Tao Chengkai just took the code in his hand, and unexpectedly the appearance of the man in black directly injured Li Quan and snatched the code.
Lin Jingshan sneaked into the ward to inject drugs into Zhu Tiande, killing him on the spot, and then returned to the car to join the man in black. The so-called man in black was Nakamura. Ma Tianming and Tao Chengkai heard the alarm and rushed forward and found that Zhu Tiande was dead. Ma Tianming tried his best to rescue Zhu Tiande, Tao Chengkai suspected that he killed Zhu Tiande.
Facing Tao Chengkai’s doubts, Ma Tianming had a mouthful and could not tell. Tao Chengkai analyzed that the murderer and the man in black should be accomplices who committed the crime at the same time, and the murderer must be an insider of the hospital. Ma Tianming thought that this would be a cause for trouble, so he proposed to lie to the outside that Zhu Tiande was not dead, so that the murderer would come to verify, and they could follow the vine to find out the real culprit.
