Episode 19 recap: Taking an oath under the national flag.

Lin Lu Xiao stood under the national flag and pledged loyalty to the country. Then, he swore that he would always remember that there was someone waiting for him at home. Lin Lu Xiao expressed to Nan Chu that his life belonged to the country, but his heart belonged to Nan Chu, and he wanted to be with Nan Chu.

Liu Ru Yi and Yu Qi Lei went to take care of Yang Zhen Gang, but they were surprised by his terrible temper. He didn't let them take care of him and even fired the nanny they had hired. Liu Ru Yi couldn't persuade Yang Zhen Gang, so she called Lin Lu Xiao and asked him to come and handle Yang Zhen Gang's affairs.

Lin Lu Xiao initially wanted to persuade Yang Zhen Gang, but when he heard Yang Zhen Gang say that he didn't want Lin Lu Xiao and the others to keep helping him, feeling that he was a burden to everyone, Lin Lu Xiao didn't say much. Lin Lu Xiao left with Liu Ru Yi and Yu Qi Lei, leaving Yang Zhen Gang alone at home. However, they were all worried and planned to find time to accompany Yang Zhen Gang again.

At night, while Yang Zhen Gang was sleeping, he felt phantom limb pain and wanted to take some painkillers. But accidentally, he spilled the medicine on the floor. After the medicine fell, Yang Zhen Gang felt upset. When he tried to get up to pick up the medicine, he saw his severed leg and couldn't help but burst into tears.

After crying, Yang Zhen Gang took the medicine and went to sleep. The next morning, Lin Lu Xiao came to take care of him. Lin Lu Xiao explained that he had a lot of annual leave and told Yang Zhen Gang to be at ease and let him accompany him. However, Yang Zhen Gang still felt burdened.

Lin Lu Xiao received a phone call and had to go downstairs to pick up a package, while Yang Zhen Gang suddenly needed to use the bathroom. But accidentally, he didn't hold onto the wheelchair properly and fell. When Lin Lu Xiao returned, Yang Zhen Gang had already urinated, and he felt embarrassed, not allowing Lin Lu Xiao to enter his room.

Seeing Yang Zhen Gang fall to the ground, Lin Lu Xiao hurriedly helped him up and cleaned him up. Yang Zhen Gang silently cried while Lin Lu Xiao pleaded with him not to push him away.

Lin Lu Xiao comforted Yang Zhen Gang, explaining that they had always taken care of each other and supported each other as comrades who had walked together. They had always been the husband and wife relationship that Yang Zhen Gang mentioned, and he couldn't disregard the injured Yang Zhen Gang.

Lin Lu Xiao returned to the squadron to handle some matters, leaving Yang Zhen Gang alone at home, feeling extremely depressed. He looked at his old photos when he was healthy and couldn't help but burst into tears. Yang Zhen Gang went to the rooftop to drink, contemplating suicide by jumping off the building. Yu Qi Lei and the others comforted Yang Zhen Gang on the scene, trying to persuade him while notifying Lin Lu Xiao to come.

Lin Lu Xiao knew that Yang Zhen Gang was fascinated by the voice of the dispatcher at the command center. He rushed to the command center to find the dispatcher named Li. Yang Zhen Gang was going through a difficult time and, while drinking, expressed his frustrations to Yu Qi Lei, asking them to leave him alone, considering his position as a commander.

Lin Lu Xiao and Liu Ru Yi both arrived and tried to persuade Yang Zhen Gang to come back and talk things through. However, Yang Zhen Gang insisted that he was now a useless person and didn't want anyone to try to talk him out of it. He wanted to bid farewell to everyone there. No matter how Lin Lu Xiao tried to persuade him, Yang Zhen Gang wouldn't listen. Lin Lu Xiao ended up scolding Yang Zhen Gang, blaming him for setting a bad example for Shao Yi Jiu and Qin Shi Quan. He said that if Yang Zhen Gang jumped, he would become the biggest joke in the fire department.

Yang Zhen Gang didn't want to set a bad example, but he felt like a burden. Even something as simple as going to the bathroom required assistance, and he couldn't accept that. Lin Lu Xiao expressed that they couldn't understand Yang Zhen Gang's pain, but they were brothers and would always be there for him.

After Lin Lu Xiao finished speaking, he connected the walkie-talkie to the command center and asked dispatcher Li to give Yang Zhen Gang a task to go and comfort the people who wanted to jump off the building. Yang Zhen Gang refused to take the walkie-talkie, so Lin Lu Xiao threw it in front of him. After hearing Li's voice, Yang Zhen Gang finally picked up the walkie-talkie.

Yang Zhen Gang reported the situation at the scene, and after Li repeatedly asked him to ensure the safety of the potential suicide, Yang Zhen Gang gave up the idea of taking his life. After Yang Zhen Gang decided not to jump, Li appeared on the rooftop and introduced herself to Yang Zhen Gang, welcoming him for completing the mission safely.

Concerned that Yang Zhen Gang would be left alone at home with too much time to think, Lin Lu Xiao went to seek help from Meng Guo Hong to see if they could arrange a job for Yang Zhen Gang that he could handle, in order to lift his spirits.

Meng Guo Hong was also aware of Yang Zhen Gang's situation and was trying to come up with a solution. However, he informed Lin Lu Xiao that it wasn't an easy task and asked him to wait for further updates. After discussing Yang Zhen Gang's situation, Meng Guo Hong informed Lin Lu Xiao that Yu Qi Lei would be promoted to acting instructor and that a new station leader would be assigned. Lin Lu Xiao was asked to wait for the new station leader to arrive for the handover.

Meng Guo Hong kept the identity of the new station leader confidential. Only when Lin Lu Xiao received the new station leader did he realize that it was Lou Ming Ye. Lou Ming Ye had volunteered to transfer to the Pinghe Road Special Operation Station. He wanted to use the advanced firefighting concepts he had learned to transform the station.

After Lou Ming Ye arrived at the station, he gathered everyone and announced his plans. He aimed to build the best special operation team in Beixun City, believing that advanced firefighting equipment could reduce casualties. He was determined to improve the special operation station. Lin Lu Xiao handed over his duties to Lou Ming Ye and shared his thoughts, mentioning that relying solely on advanced firefighting equipment might not necessarily enhance firefighting and rescue techniques.

After the handover, Lou Ming Ye went to visit Yang Zhen Gang to explain his ideas and his current role.
