Episode 12 recap: Li Guo has completed her final act of revenge.

At the press conference, they also released the audio recording of a conversation between Tang Dade, Zhou Hao, and He Jingzhi, in which they conspired to murder Professor Song. Tang Dade was completely devastated at the scene, and what made it even more devastating for him was that the mastermind behind all of this was his own wife, Li Guo. Years ago, they had co-researched a patent with Professor Song, but Song did not want to publish it. However, Zhou Hao knew that once this patent was published, it would bring endless wealth. Zhou Hao knew that Tang Dade was in love with Li Guo, so he came up with a permanent solution - as long as Professor Song was gone, Tang Dade could have Li Guo, and they could profit from the research results.

He Jingzhi overheard this. Originally, Tang Dade did not want to do this, but after being explicitly rejected by Li Guo, he steeled his resolve and decided to follow Zhou Hao's plan. At that time, Tang Dade's mind was clouded by love and the temptation of fame and fortune. He did not realize that Professor Song would sacrifice his own life to save them. If he had known the outcome, he would not have agreed to harm Professor Song.

Tang Dade told Li Guo that he was only an accomplice, and that he had only done it because he loved her so much and wanted to be with her. Li Guo handed over the USB drive containing the evidence to Tan Jingtian, but Tan Jingtian noticed a syringe in her bag and quickly realized that Li Guo intended to inject Tang Dade with bee venom. Tan Jingtian stopped her.

At this point, Tan Jingtian also noticed the bee sting marks on Li Guo's injured body, and he knew that she had also killed He Jingzhi and Zhou Hao in order to avenge Professor Song. However, Tan Jingtian had his own ulterior motive - he did not want Li Guo to destroy her own life. At this moment, Tang Dade should have also figured it out, and he then took the initiative to admit that he had killed He Jingzhi and Zhou Hao. But this did not make logical sense, because this occasion was extremely important to Tang Dade, so how could he have placed Zhou Hao's body at the press conference, exposing the crime publicly?

Li Guo did not expect that Tang Dade would take the blame for her, but she did not want it to be that way. She took out the bee venom syringe and pointed it at her own neck, recounting her own criminal process. After hearing the recording of the three of them, she had developed the intention to kill, but she knew that Tang Dade was only an accomplice, so He Jingzhi and Zhou Hao were the ones she hated the most.

During the investigation, there was evidence that on the day He Jingzhi died, Li Guo was with her uncle and also had a video call record with Tang Dade, but all of this was pre-arranged by her. She had brought her uncle and family members to the Jiang River, had the video call with Tang Dade during dinner, and then went to commit the crime, which did not take much time at all.

Moreover, she accurately described how she had extracted the bee venom herself, which Tan Jingtian also discovered. Tan Jingtian had no choice but to tell the truth, but he was trying to stop Li Guo from killing Tang Dade again. Although Tang Dade deserved to die, he should face legal judgment.

In the end, Li Guo injected the bee venom into her own body, as this was her final act of revenge. She knew that Tang Dade loved her, and if he had given up the press conference the day before, she had already decided to forgive him and maybe even continue living with him. But she never imagined that he would still be so obstinate, so if she couldn't end him, she would end herself. She wanted to ensure that Tang Dade would spend the rest of his days in agony, wishing for death.

Although Li Guo was rushed to the hospital immediately, her chances of survival were slim. She recalled the period when she had wished for death after Professor Song's death, and how Tang Dade had saved her each time. It was during that time that she had been touched by Tang Dade, but after learning the truth, all of that had become utterly nauseating to her.
