Long Dongdong sees Liu Zhengliang's capabilities and offers to help him change his registered practice location to Xiaoximen Hospital, enabling him to operate legally. However, the condition is that he must stay and work at the rundown Xiaoximen Hospital.

Liu Zhengliang returns to the hospital ward to visit his brother, Liu Zhengguang, and discovers that he doesn't actually work for a foreign enterprise like he thought all along. Liu Zhengliang is then set on finding a different job for him.

Jia Xin brings his mother, Duan, to see a doctor. She insists on having an IV drip without undergoing any tests, and she's so stubborn that no one can talk her out of it. Liu Zhengliang claims he's staying out of this, but puts on his white coat and takes over anyway.

Che Mingming examines a young girl and determines that she has multiple fractures to her left skull and is on the verge of death. There is no time to transfer her to another hospital. Given the high risks associated with the surgery, everyone pins their hopes on Liu Zhengliang.

Liu Zhengliang still says that he wants to return to the south, but he has already been tied down by Zhang Jiao.

They finally find Li Zhongling's body. Liu Zhengliang suggests, "No funeral. Just cremate her". Liu Zhengguang accuses his brother of being heartless, and the two argue again over their mother's funeral arrangements.

Liu Zhengliang uses work to numb himself. As Long Dongdong puts it, Liu Zhengliang is the one holding the key. No one else can help.

Long Dongdong drags Liu Zhengliang to have his professional portrait taken, then turns around and uses it for a flashy poster that hangs high on the side of the building. He also promotes Liu Zhengliang to deputy chief of both the Emergency Department and the Neurosurgery Department.

Liu Zhengliang sees a patient named Shao Nan, who suffers from abdominal pain. Her husband, Jiang Chao, refuses a blood test, so Liu Zhengliang can only prescribe her anti-diarrheal medication and request that she stay for observation. Soon after, Shao Nan goes into shock and passes away.
