Deep in the Interpol archives, there is an encrypted file labeled "Project Black Tower". Three years ago, an explosion occurred in a secret biological laboratory in a Southeast Asian country, killing 12 top scientists, including Chinese bioinformatician Cheng Yanqiu, the brother of senior Interpol agent Cheng Mo. The official report stated that the accident was caused by an experimental error, but when Cheng Mo was sorting out his brother's belongings, he discovered a bronze key engraved with the word "zhou" and a set of encrypted data.
At the same time, there is a legend circulating in the underground intelligence network: Zhou Lin, the "Night Owl" who controls half of Asia's underground intelligence market, holds the "Black Tower Key" that can open the global darknet database. This key can not only access priceless confidential information, but may also reveal the truth about the explosion three years ago...
Cheng Mo took the initiative to invite Miao to sneak into Zhou Lin's circle. After two years of disguise, he successfully approached Zhou Lin's inner circle as an art appraiser, but he could never find the exact whereabouts of the key. Until that rainy night, the headquarters intercepted information: Zhou Lin would display a new batch of collections in a private museum, which may include keys. But is the truth really what they know? Who was behind the explosion? What secrets are hidden at the top of the organization?
