Luo Yifeng is the Chief Investigator of the Independent Commission Against Corruption. He was ordered by the Director to set up a special team to use the cryptocurrency market-making case to investigate the corruption of a bank executive. Luo Yifeng then sought help from Xu Xin, the software designer of the trading platform of Gaibi, hoping to use high technology to enter the platform to search for evidence. After checking, they found that there were discrepancies in the bank's finances, and locked the suspect as the bank executive He Jintao. During the process, the person under investigation was attacked by a mysterious person, and at this time the chairman of the bank was also kidnapped. However, the kidnappers not only posted the kidnapping clip on the Internet to attract public attention, but also demanded that the Gaibi related to the market-making case be used as a payment tool. Because of various coincidences, Luo Yifeng believed that the mastermind behind the market-making case and the kidnappers were the same person, and the Independent Commission Against Corruption vowed to do its best to catch the murderer.
