Episode 26 recap: The Comprehensive Governance Center is investigating the source of pollution.

Someone came to inform Xiao Li Ming that there is new information regarding the issue of contaminated fish. It turns out that a feed-selling company has come forward. Xiao Li Ming finds it strange and suspects there may be other problems. Representatives from the Comprehensive Governance Center come to investigate and determine if it is environmental pollution. Ma Le has already found out that the water pollution is caused by a chemical factory upstream.

The Comprehensive Governance Center is discussing how to resolve the issue of the contaminated fish and identify the source of pollution. Someone informed Xiao Li Ming that a person named Qiao Lei from a feed-selling company has confessed. Qiao Lei claims that there was a problem with their feed, which led to the contamination of the fish.

Now Jiang Chuan Lai's father can go back home. Ma Le accompanies Jiang Chuan Lai's father and when he sees Jiang Chuan Lai, he feels guilty. Ma Le asks Jiang Chuan Lai's father for the fish feed they usually use to feed the fish, mentioning that he will take it for testing.

Xiao Li Ming calls Dr. Zhang. Dr. Zhang is now married to his senior and feels that Xiao Li Ming and the others are too busy with work, regretting that they couldn't attend their wedding. Xiao Li Ming hopes that Dr. Zhang can help him test the fish feed. Dr. Zhang readily agrees.

The children are practicing basketball. They ask Coach Jingyi when they can come back, as they feel that without them, the team is incomplete, and they won't be able to compete. The coach tells them to focus on their training and not worry about other things. Qiao Lei and the others return, and everyone is happy. Xiao Li Ming receives a call from Dr. Zhang, who states that except for the deficiency in vitamins, there doesn't seem to be any other problems with the feed.

Xiao Li Ming finds it strange and suspects there may be other issues.

Ma Le believes that Qiao Lei's sudden confession either means there are benefits involved or he is taking the blame for someone else. Xiao Li Ming thinks this matter needs to be investigated thoroughly. Representatives from the Comprehensive Governance Center come to investigate, wanting to determine if it is environmental pollution.

The Environmental Protection Bureau takes samples for investigation and testing. They discover that the components in the wastewater discharged by the printing and dyeing factory here are identical to those found in the contaminated fish. Ma Le calls Xiao Li Ming and informs him that they have found out it is water pollution caused by an upstream printing and dyeing factory.

Xiao Li Ming and the team come to investigate in the Mianran area. They want to collect samples from here. Mo Wen Er appears and allows them to freely investigate. It is then that Xiao Li Ming realizes that Mianran is actually an industry under Mo Wen Er's name. Mo Wen Er claims that they have already introduced highly advanced wastewater treatment equipment and there shouldn't be any issues. They suggest investigating the small factories, preferably at night when there might be instances of secret filming. Xiao Li Ming assures Mo Wen Er that they will conduct the investigation.

Mo Wen Er approaches Mr. Ni and expresses her deep concern about the situation. Mianran is currently a leading entity in the industry, and if any problems are exposed, it would be disastrous for her. Mr. Ni tells her not to worry too much and suggests she seek the assistance of Mayor Su, as it would only take a few words without causing any mistakes on Mayor Su's part.

Internet celebrity Xiaotian is secretly live streaming in this area. Someone sends a gift, prompting Xiaotian to investigate and find out if there are any issues behind this company. In the middle of the night, Xiaotian sneaks into Mianran and captures evidence of their secret wastewater discharge. The situation turns out to be more serious than expected. The pollution testing report is now available, and considering the production capacity of those small printing and dyeing factories, even if they had been discharging for 20 years, it would still be impossible to reach the current level of pollution.

Xiao Li Ming expresses that this is the last thing they wanted to see. It appears that the problems with these large factories are indeed severe. They still need to investigate these factories thoroughly to determine the root cause of the issue.
