Episode 34 recap: Qi Heng successfully cleared his suspicion.

Just as Qi Heng finished cooking at home, Lao Hou arrived shortly after. Once he entered, he didn't consider himself an outsider and immediately picked up utensils to prepare for a meal. Lao Hou brought up the case, and the current situation is highly unfavorable for Qi Heng. Guo Lun also tried to find evidence of Qi Heng's visit to the gas station on that day through the computer. Upon learning about it, Ma La Song also wanted to investigate together, but Qi Heng remained unaware of this.

Ma La Song and Lao Hou's group arrived at the hotel, recalling that the chemical plant manager had received a letter here in the past, which included the sender's address. However, the chemical plant manager has disappeared, likely having gone to his cousin's place in Sanya. After investigating, the police discovered that the manager had actually flown to Sanya on the day in question and have now located him.

The police quickly brought him back and asked him to identify the appearance of Guo Nian and another man he had seen in the forest several years ago. The manager's identification further confirmed that the person was Zheng Duo. Zheng Duo was brought in for questioning again, but Chen Shu was constantly there to defend her. Zheng Duo denied having seen Guo Nian, and in addition, Zheng Duo was currently in a state of medical parole. Furthermore, the director's photo was not accurate enough, so they couldn't fully arrest Zheng Duo as a suspect.

Ma La Song's group also helped in their efforts to clear Qi Heng's suspicion. They later found Lao Hou and hoped he would disclose some details of the case, but Lao Hou naturally couldn't violate his professional ethics. Ma La Song discovered a crucial clue: although Qi Heng returned to the city, it would have been challenging for him to travel to the village and harm his wife, Guo Nian, within four hours. They hoped to use this information to remove Qi Heng's suspicion.

Zheng Duo met with Secretary Su, who disguised herself for the meeting. It turned out that Zheng Duo came for money this time. Secretary Su obtained further confirmation from Zheng Duo that he was indeed the one who killed Guo Nian. It appeared that Hu Bai was also killed because he had learned about the secrets of the chemical plant. It seemed that Zheng Duo had done a lot of things.

Through Guo Lun's relentless efforts, they finally found the video evidence proving Qi Heng's presence at the gas station. With this video, Qi Heng's suspicion could be successfully cleared. On the contrary, they discovered a video of Zheng Duo driving towards Matou Village, and they also noticed a piece of clothing belonging to Guo Nian on the passenger seat.

Because Zheng Duo's car was speeding, the photo was continuously saved. When Zheng Duo was questioned at the police station, they didn't say a word, and it was only Chen Shu who defended them. Zheng Duo finally spoke up but claimed that the clothes in the car didn't belong to Guo Nian, but to another lover. Since the evidence was still insufficient and Chen Shu was speaking in favor of Zheng Duo, they were able to leave the police station smoothly.

Coincidentally, when they came out, they encountered Guo Lun and his group face to face. Guo Lun almost rushed over to attack Zheng Duo but was stopped by Ma La Song and Qi Heng. Guo Lun showed the video to Lao Hou's group, and Ma La Song also noticed a familiar face in the video, recalling that it was the plaintiff in a previous case. They quickly found the person, hoping to retrieve the work they filmed six years ago.

Interestingly, the person had filmed the gas station staff, and Qi Heng actually appeared in the footage. With this photo, Qi Heng's suspicion was truly cleared. Qi Heng was still analyzing the situation with Lao Hou, and although they had brought back hair for DNA testing, not every strand had been tested. They discovered that three of the hairs did not belong to Guo Nian.

In fact, during the argument between Guo Nian and Zheng Duo, Guo Nian unintentionally pulled out a few strands of Zheng Duo's hair. This turned out to be a significant discovery for the police, and they quickly prepared to arrest Zheng Duo. However, they were unaware that Zheng Duo had already received the news and fled.

Luo Huai Gong couldn't hold back the information and expressed that Zheng Duo must not fall into the hands of the police. During a meeting, Luo Huai Gong showed the photos to the leaders, allowing them to conclude that Qi Heng was not the culprit behind Guo Nian's harm. Qi Heng had sufficient evidence to prove their absence from the scene. Lao Hou also mentioned that they had identified the suspect, but it seemed that the other party had known about it in advance and escaped.

Luo Huai Gong deliberately told Aunt Ling that he had bought a villa and a car in Macau in their daughter's name, but the matter was not yet settled. Aunt Ling was very angry, feeling that this matter had already harmed Wu Shen Yuan.
