In the busy city, the corridor outside the central operating room seems particularly quiet.After a long wait, Goldin finally received some pretty good news.Although Park Jin-yeon's internal organs were severely damaged, his life was temporarily saved.In the ward next door, Zhang Shengzhe and Director Cui also successfully survived the dangerous period.

At the same time, Bai Lumi and others were arrested on suspicion of crimes and were quickly transferred to the interrogation room.In the face of conclusive evidence, Gu Yingtai had to admit that he witnessed Gu Shutai killing the investigator.The brothers shirk responsibility from each other, but Kang Ha Nai decisively identifies them as accomplices and pursues corresponding criminal responsibility.

Bai Romi's case was handed over to the investigation team by Jiang Henai.After the trial, Zhang Shengzhe took the initiative to find her and announced the winner or loser of the contest.After this incident, Zhang Shengzhe felt deeply guilty. He realized that violence would only bring more violence, and revenge could not completely resolve the grudges.Therefore, he decided to disband his group and bear the consequences alone.

However, his decision was not supported by Kim Do-ki, Go Eun and others.They all expressed their willingness to advance and retreat with him and face future challenges together.At this time, good news came from the hospital: Park Zhenyan had regained consciousness.Everyone couldn't wait to visit him. Although everyone was injured to varying degrees, fortunately, they were all safe.

During the interrogation of other criminals, Kang Ha Nai learned some information about the underground prison, including the fact that Kim Doji had participated in the imprisonment.Kim Do-ki followed Kang Ha-nai to the Mental Health Sanatorium and finally met Choi Jong-sook who had been missing for many days.However, at this time, Cui Zhongshu had no impression of Kim Doji. The only thing she remembered was the basement that cast a great shadow on her.

After seeing Choi Jong-sook, Kim Do-ki took Jiang Ha-nai to the dark and cold basement.It was filled with a rotten smell, which made Kang Ha Nai very angry.He accused Jin Daoji and others of being too cruel, while Jin Daoji explained that his original intention was to protect more people.He hoped that Jiang Henai would let him solve the matter at hand first and then face the punishment he deserved.

At this moment, the prosecutor's office and Zhang Shengzhe's home suddenly received a confession letter from the prison.The sender is none other than serial murderer Wu Zheyong.Through Wu Zheyong's narration, two murder cases from many years ago were uncovered.One is the case of a female high school student in Dangsan-dong, and the other is the murder of a woman in Hwahwa-dong.

In the letter, Wu Zheyong described in detail how he killed Kim Doki's mother.The police mistakenly targeted Nam Kyu-jeong in their investigation, leading to one innocent person being named as the murderer and another innocent person choosing to surrender.Now, Wu Zheyong is still in prison, and Zhang Shengzhe ran to ask him about his true intentions.However, Wu Zheyong's answer sent chills down Zhang Shengzhe's back.He couldn't understand why someone would take pleasure in killing people and play with the pain of their victims.

At the same time, Kang Ha-nai retrieved the file again and compared the DNA in the female high school students in Tangsan-dong with Oh Cheol-young.The results were surprisingly consistent.Kang Ha-nai immediately reported the situation to Deputy Chief Cho, and the two went to see Kim Cheol-jin in person - an innocent person who was unfortunately involved in the rape and murder of a female high school student in Tangsan-dong and was eventually violently interrogated by the police.

Kim Cheol-jin's wife and children separated when he was in prison, and he suffered discrimination and criticism after he was released from prison.Since the statute of limitations for prosecution has expired, he cannot clear his grievances through legal means.After receiving a call from Zhang Shengzhe, he confided his experience to Jin Daoji and made the decision to take revenge.Kim Do-ki accepted the case and began to prepare a plan to try to get close to Oh Cheol-young.

When Kang Ha Nai personally interrogated Oh Cheol Young, he found that the other party was inhumane and even asked to meet with the victim's family.Because only the victim's admission is considered evidence, Kang Ha Nai contacted Kim Do Ki to meet Oh Cheol Young.Kim Do-ki fell into shock when he heard Oh Cheol-young slowly speaking out his mother's last words in the interrogation room.His mind was filled with images of the murder scene, and he was curled up on the ground in agony.After he gradually recovered, he rushed out of the interrogation room and chased after the escort vehicle to kill the devil.

However, Jin Douji also knows that his actions may bring greater trouble and consequences.He must proceed carefully to ensure that his plan succeeds.At the same time, he also has to face his own inner struggles and contradictions.Should he sacrifice his conscience and morality for revenge?This is something he needs to think about seriously.
