On his way to pay homage to his late wife, Yang Guangyao came up with the idea of ​​asking his wife for advice.At this time, Dr. Zhou came unexpectedly and confessed that he had recognized Yang Guangyao's identity when he first met him, and even guessed their father-daughter relationship from his conversation with his daughter.Yang Guangyao then recounted his bizarre experience leading up to this investigation. Dr. Zhou was convinced after hearing this and decided to respect his daughter's decision from now on, and dissuaded Yang Guangyao from pursuing her husband's case, but he was refused.

Back at their residence, Yang Guangyao and Zhang Tianming discussed again the name change of Medical Examiner Chen.Soon, Dr. Zhou called and said that he had found evidence that her husband had changed his name.Zhang Tianming immediately called relevant people and mentioned Zhuang Xiaohua's disappearance. Yang Guangyao rushed to the scene after hearing the news.

At the same time, the kidnapped Zhuang Xiaohua revealed his plan to contact Sang Da Shi, but this aroused the vigilance of Forensic Chen.He quickly knocked out the others and fled the scene with Zhuang Xiaohua.After treating Zhuang Xiaohua in the hospital, Zhang Tianming and others began to interrogate him about the truth about the fire in the Invesco Building, but Zhuang Xiaohua continued to play dumb and even asked a lawyer to intervene.

Yang Guangyao once again met with Dr. Zhou to talk about her husband's affairs, hoping that she could help find evidence.Dr. Zhou secretly went back to his room to look for his husband's belongings, and his daughter followed quietly.Yang Guangyao concealed the truth because he was worried about his daughter being harmed. However, as a police officer, Chen Kaiqing still insisted on knowing the truth and took the initiative to join the team looking for evidence.When the urn was discovered, forensic doctor Chen suddenly appeared and flushed the evidence into the toilet sadly, vowing to let the unfaithful father never have peace.

In the dead of night, Forensic Chen could not sleep. The image of him chaining his father up appeared in his mind.Chen Kaiqing felt strange about what her father had done and confided in Zhang Tianming.Zhang Tianming believes that there is currently a lack of strong evidence, and his first priority is to prevent the behind-the-scenes gangsters from dealing with Sandus, and hopes that Sandus can leave evidence before leaving Hong Kong.

In order to get close to Sandus, Zhang Tianming went to the hospital to find Zhuang Xiaohua, saying that he would not give up investigating the Invesco Building because of her silence, and asked her to introduce him to Sandus.When Zhang Tianming returned to join Yang Guangyao and others, he proposed a plan to join the Sandus camp to find evidence.After Yang Guangyao reluctantly agreed, he had a heart-to-heart talk with Zhang Weitao at the beach, recalling the past of rescuing people.Zhang Weitao said bluntly that he had never thought about getting married because he was worried that he would not be able to protect his partner.Yang Guangyao was deeply moved after hearing this.

Zhuang Xiaohua introduced Zhang Tianming in front of Sang Da Shi.Forensic Doctor Chen revealed his plan to leave while having dinner with his wife. Dr. Zhou immediately informed Yang Guangyao after learning about it.At the same time, Dr. Zhou's late-night phone call alerted her husband.
