Episode 5 recap: Zheng Ren was diagnosed with abdominal cocoon syndrome.

Zheng Ren received a sudden notification and went to the hospital. After viewing the film, Zheng Ren asked Zhou Li Tao for additional information. At this moment, Lin Ge arrived and, after looking at the film, speculated that it resembled fibrosis of the entire digestive tract. The patient also experienced abdominal pain and had a lean body, but mucosal hyperplasia would form granulation tissue, although it was not visible at present. Lin Ge expressed the need for some previous cases for a definite diagnosis and was surprised to see Lin Xiuying. He felt that he recognized this person.

Zheng Ren instructed Xiao Zhou to perform tumor marker tests, tuberculosis indicators, autoimmune indicators, and a gastrointestinal endoscopy for the patient's monitoring. Zhou Li Tao mentioned that the patient had already undergone these tests at another hospital. However, Zheng Ren insisted on conducting them again. Lin Ge felt displeased that Zheng Ren was ignoring him and continued to explain that the patient was Peng Jia's wife, which made Zhao Xin realize that this situation might be troublesome.

Zheng Ren and Lin Ge kept searching through medical literature and references to find the source of this condition. Su Li also arrived after hearing the commotion and asked if they had identified the cause. She urged them to transfer the patient to a higher-level hospital for treatment. As soon as Su Li finished speaking, Zheng Ren immediately suggested open abdominal surgery, suspecting it was abdominal cocoon syndrome.

Lin Ge thought that abdominal cocoon syndrome was far-fetched and didn't fit the symptoms. Zheng Ren explained to Lin Ge that this condition was rare, with an unknown cause and varied presentations. Lin Ge was curious about how Zheng Ren made the decision. When Su Li asked Zheng Ren about his confidence level, he hesitated because he had never performed such a procedure before and would only know the certainty after opening the abdomen.

Upon seeing the diagnosis as abdominal cocoon syndrome, Su Yun believed that if they performed surgical resection, the patient would require lifelong medication through intravenous injections. Su Li realized the gravity of the situation and wanted to immediately inform the patient's family and transfer them to another hospital. Zheng Ren preferred to operate on Lin Xiujia, while Su Li wanted to minimize the hospital's risks. However, when Su Li saw the young girl, she softened her stance, and Zheng Ren insisted on performing the surgery, to which Su Li agreed.

Zheng Ren directly informed Lin Xiujia that this condition was rare and that the surgery held uncertainties. Lin Xiujia expressed a desire for Zheng Ren to help her live for another six months, to which Zheng Ren promised to do his best. In truth, Zheng Ren had experienced similar feelings during his childhood, and this incident had always been a shadow in his heart. When he was young, he witnessed his mother covered in blood, collapsing helplessly in front of him.

Zheng Ren performed the surgery on Lin Xiujia, and Zhao Xin remarked that the procedure was challenging. Su Li stood by, comforting the young girl. Zhou Li Tao also admired Zheng Ren, and Zhao Xin exchanged a glance with Zhou Li Tao.

Su Li stayed with the young girl, reminiscing about how her loved ones had all left her one by one in the hospital during her childhood. The only person who came out was her ex-husband. Lin Ge was also impressed by Zheng Ren's surgical skills, while Zhao Xin stubbornly insisted that Zheng Ren was still young.

Zheng Ren's gaze became absent-minded, and he struggled to hold on until after the surgery. He was reminded of the scene from his childhood when his father jumped off a building, and it jolted him awake. Su Yun shouted that Zheng Ren had a fever but still insisted on working. Su Yun tried to console Zheng Ren, but he was straightforward and brought up the thing Su Yun cared most about—why he wasn't the primary surgeon. Su Yun visibly retracted her smile.

Peng Jia arrived at the hospital and went crazy, shouting at Lin Xiujia for not going to the hospital. Su Li quickly called the security. When Peng Jia heard her daughter say that he wasn't a good father, he became agitated and grabbed her. Zheng Ren intervened and had someone inject medication into Peng Jia, keeping him hospitalized for observation. Su Li criticized Zheng Ren for disregarding his own health and performing the surgery. She believed it was the responsibility of many people, and all colleagues should bear the burden.

Zheng Ren agreed with Su Li's statement. The medical report on Peng Jia came out, revealing renal failure, mania, and heart failure. Zheng Ren wondered how to find the source of the illness, while Su Yun believed that Peng Jia's daughter was the most important. With Su Yun and Chang Yue accompanying her, Peng Jia's daughter came to Peng Jia's office to look for something.

Su Yun noticed the drawing the little girl wanted to take and realized that Peng Jia might have worked hard and drank coffee to make her daughter proud. Zheng Ren was touched by the words of the little girl and his heart softened. Zheng Ren received unanimous praise, and Lin Ge felt uncomfortable, but he still went to receive another patient.

During Lin Ge's surgery, it was difficult to remove the stones, which made it challenging for him. Su Li anxiously watched from outside. While Zheng Ren was inspecting the hospital's new machine, he was informed by Su Li that he was needed in the operating room.
