Episode 1 recap: Zheng Han Jiang is under investigation by the disciplinary committee.

In 2016, at the Qijiang University auditorium, Zheng Han Jiang (played by Huang Zhi Zhong), the vice president of the university and the dean of the School of Environment, was giving a lecture. Li Zi Ping, the mayor of Jiangzhou City, was leading the leadership team and listening to the lecture. However, Deputy Mayor Wang had not arrived yet, and they were worried when they found out.

Zheng Han Jiang was talking about the harmful effects of the deteriorating environment on human beings, and the urgent need to address ecological problems. At this time, Deputy Mayor Wang was still unreachable, and Zheng Han Jiang was also inquiring about his whereabouts. They had studied environmental issues together when they were graduate students, and the secretary was also trying to contact Wang. Seeing that Wang had still not arrived, Li Zi Ping angrily went out to make a phone call.

Finding Wang Wu was now the top priority. Wang Wu was the deputy mayor in charge of the environment. Currently, the central inspection team was discussing environmental rectification issues at a hotel. Wang Cheng, the leader of the inspection team, was briefing his subordinates about the environmental problems in Jiangzhou City. Wang Cheng also joked that Wang Wu was very smart, but despite all this time, Wang Wu had not shown up.

Little did they know that at this moment, a bloated body was suddenly found by the river, and the fishermen immediately reported it to the police. Soon, everyone attending the lecture received the news that Wang Wu's body had been found by the river, and the situation became grim. Zheng Han Jiang, seeing that all the important leaders in the front row had left, also felt that the situation might not be good.

Li Zi Ping instructed his subordinates to inform everyone of the latest news about Wang Wu. Soon, fewer and fewer people were left listening to the lecture, and by the time Zheng Han Jiang turned around to write on the blackboard, more than half of the people in the audience had already left. Wang Cheng also learned about Wang Wu's death and, through a simple analysis, determined that he had died early this morning.

Just at that moment, Wang Cheng's inspection team received a package at the hotel entrance, with instructions for Wang Cheng to open it. The police chief evacuated the surrounding staff, and Wang Cheng walked out of the hotel. The address of the hotel where they were staying was known to only a few leaders, but Wang Cheng still opened the package. To his surprise, inside was a smelly fish with black liquid coming out of its mouth. Wang Cheng ordered his subordinates to investigate immediately.

Liao Yu Zheng, the secretary of the municipal party committee, also learned about Wang Wu's incident. At the moment, they considered the possibility of Wang Wu being murdered to be relatively low, but they did not rule out the possibility of accidental drowning after drinking. Surveillance footage revealed that Wang Wu was indeed alone before he jumped into the river. Soon, news of Wang Wu drowning would spread among the people, so they must provide a reasonable explanation.

After the investigation, it was discovered that Zheng Han Jiang and Wang Wu were actually classmates. Upon learning this, Liao Yu Zheng immediately sent someone to find Zheng Han Jiang. The next step was to reassign Wang Wu's work to other subordinates. Wang Cheng, as the head of the inspection team, provided feedback and shared the investigation findings with everyone. Some people emphasized the need to pay more attention to environmental hygiene in the future.

Executive Chairman Liu Geng Ye was discussing recent industrial developments with Wang Cheng, but Wang Cheng abruptly interrupted him with just two words: "tear down." Wang Cheng mentioned that Qijiang was originally intended for agricultural land reclamation but ended up becoming a real estate project. Despite the large industrial park, the pollution situation was extremely poor. He mentioned the current difficulties but also highlighted that the responsibility for environmental protection was not solely on Wang Wu. Each person had a role to play. Wang Cheng expressed his determination not to compromise this time, and he urged Liao Yu Zheng to announce during the meeting that there should be no relaxation in the upcoming minutes and seconds. Currently, some people were happy while others were worried. Liu Geng Ye had already signed a contract with the developers, but now, due to Wang Cheng's words, their contract would be canceled.

Zheng Han Jiang was originally playing basketball at the sports field when he was suddenly called away. He wasn't even given a chance to pick up his child from school. Zheng Han Jiang wanted to contact his wife, Xiao Xue, but she was undergoing surgery and couldn't be reached.

Since Zheng Han Jiang had dinner with Wang Wu last night, he became one of the suspects. Zheng Han Jiang truthfully recounted the events of yesterday, but the leaders demanded that he provide a detailed account of all the conversations and time between the two. At this point, Zheng Han Jiang was still unaware of the news of his old classmate's death. He only learned about the discovery of Wang Wu's body this morning from the leaders, which surprised him greatly.

Subsequently, the police launched a series of investigations into Wang Wu's case. Zheng Han Jiang, who still couldn't accept the news of his old classmate's death, recalled that Wang Wu had consumed a considerable amount of alcohol last night and even cried, expressing his emotional distress. After Xiao Xue finished her surgery, she learned that her husband had been taken away by the disciplinary committee for investigation. Meanwhile, their daughter was still at the dance training center because there was no one to pick her up after class. Xiao Xue hurriedly took a taxi to pick up her daughter, fortunately finding her daughter not upset.

When they were drinking last night, Zheng Han Jiang felt that something was off with Wang Wu. The surprise on the faces of the disciplinary committee's investigators was evident when they saw Zheng Han Jiang appearing very calm. Other people, upon learning about Wang Wu's death, showed more fear and concern, but Zheng Han Jiang appeared unusually composed.

Zheng Han Jiang was released late and returned home to his waiting wife. The police had now found a car that appeared at the restaurant entrance and under the bridge, and it could potentially be the key to Wang Wu's suicide.
