She is the organization's best chemist, but she uses her lifelong learning to formulate an antidote that can untie all drugs. He is the most cold-blooded executioner of the organization, but he made an exception and left a chance of survival for a traitor's daughter. When the black organization ushered in its collapse, the deepest rift between Gin and Conan was actually carved by that unknown female researcher - she was both a rose and a sting. In the final showdown, who is the real winner?
Concept: This work is based on the main line of the black organization in "Detective Conan". Lin Gui, an original genius chemical researcher, is in the core circle of the organization with her top chemical abilities. On the surface, she is following the organization's instructions to develop control drugs, and secretly researching an antidote that can neutralize the harm of APTX4869. She is torn between the cold and cruel Gin and the truth-seeking Conan. The story focuses on the complex and multifaceted aspects of human nature: there is no absolute black and white, and people trapped in the quagmire of darkness can still maintain goodwill and perseverance; through layers of intelligence games and drug offensive and defensive duels, it shows the protagonist's growth line to break through the shackles of the organization and disintegrate the dark forces, and explores the individual's struggle and redemption in the huge evil system, as well as the deep meaning of truth, life and justice.
