Lin Feng, an antique physical-chemical appraiser, discovers during a live stream connection that pregnant internet celebrity Bai Tingting is wearing a Fengxue jade pendant containing hidden deadly toxins. When he kindly advises her to take it off, he is instead cyberbullied and slandered. Obsessed with the rumor that 'jade can nourish people,' Bai Tingting insists on wearing it close to her body, and gradually begins showing symptoms of poisoning. Even after switching jade pieces to participate in a high-stakes gambling appraisal, the truth about the toxic objects cannot be concealed. Lin Feng gathers testing evidence, withstands criticism from the entire internet to popularize hardcore science, step by step ferrets out the criminal gang manufacturing and selling toxic imitation antiques, uses science to debunk antique scams, and protects the public from the harm of hazardous antiques.
