Episode 14 recap: Tan Dade's Secret Exposed

Tan Jing Tian handed over the USB drive that Li Guo gave him to the police, and recounted his suspicions. At the time, he deliberately mentioned in front of Tan Dade and Li Guo that Liu Xiao Yu died in an accident, and they were both very shocked. Tan Jing Tian could not determine who the murderer was, or whether the two of them were colluding.

So he intentionally brought up the Bai Juhua incident, so that whoever contacted him to inquire about the situation would be the one who could clear their suspicion. Sure enough, the person who called was Li Guo, just as Tan Jing Tian had hoped. Tan Jing Tian told Li Guo the results of the investigation, that Liu Xiao Yu's death was likely due to Professor Song's manuscript from back then.

Initially, Professor Song discovered the technology his students were researching, which could greatly reduce insect populations and protect crops, but it would cause great harm to insects, especially butterflies, and could even lead to their extinction. So Professor Song unhesitatingly abandoned this groundbreaking technology. But someone wanted to profit from it, so they desperately wanted to get that manuscript, and both Professor Song and Liu Xiao Yu died because of it.

Li Guo knew that Tan Jing Tian had started suspecting Tan Dade, and she was heartbroken, never imagining that she had married the man who killed Professor Song. Tan Jing Tian hoped that Li Guo could help him, as he suspected that Tan Dade was impersonating Liu Xiao Yu and trading murders on the dark web. There would be traces of logging into the dark web, so he hoped Li Guo could help verify this, which led to the USB drive incident, where Li Guo copied Tan Dade's dark web login and chat records while he was off guard.

Because of this, Li Guo decided to eliminate Tan Dade in order to avenge Professor Song and Liu Xiao Yu.

Liu Xiao Yu's depression was also caused by Tan Dade. He was a very trusted and highly regarded student of Professor Song's. Professor Song had instructed Liu Xiao Yu to take the manuscript to the office and shred it, emphasizing that he should personally complete this task. But on the way from the lab to the office, Liu Xiao Yu changed his mind and secretly kept the manuscript.

After Professor Song's incident, He Jingzhi and Zhou Hao searched Professor Song's lab for the manuscript and destroyed anything that could incriminate Tan Dade, because they had decided to make Tan Dade the founding researcher of the patented technology, so they couldn't leave any traces for others to suspect him. Tan Dade discovered their actions and was worried about being seen, but under the urging of Zhou Hao and He Jingzhi, he also joined them in the search.

In Thailand, Liu Xiao Yu noticed that Tan Dade seemed very interested in the manuscript, but he accidentally let slip that he knew about the manuscript. However, seeing Tan Dade's reaction, he lied and said he had only glimpsed it in China and couldn't remember it. Later, Tan Dade intentionally helped Liu Xiao Yu move, using the opportunity to check his belongings but couldn't find the manuscript. Unluckily, Liu Xiao Yu caught him secretly going through his things.

Liu Xiao Yu's mental state deteriorated further. He moved into the apartment Tan Dade and Li Guo had rented for him, and started checking for hidden cameras or bugs. He was very afraid whenever he was alone with Tan Dade, even afraid of him. However, Tan Dade kept trying to get Liu Xiao Yu to continue the work Professor Song didn't complete, guessing that Tan Dade just wanted to use him to obtain the manuscript and publicize the technology.

When Tan Jing Tian learned that Liu Xiao Yu was suffering from depression, he was very concerned, and secretly went to talk to Tan Dade and Li Guo, taking the opportunity to suggest that they let Liu Xiao Yu return to the country to recuperate. This made Tan Dade quite anxious, as he didn't want Liu Xiao Yu to go back, so he decided to resolve the situation with Liu Xiao Yu quickly.
