Meng Yi is the most sought-after young associate professor in the History Department of Jiangcheng University. He wears a pair of gold-rimmed glasses all year round and has a gentle smile on his lips. He is a perfect scholar who is humble and polite in everyone's eyes. However, beneath this extremely deceptive skin, there is hidden a soul that is extremely self-interested, proficient in calculations, and treats everyone as pawns. An accidental weekend treasure hunt at a second-hand market, the ancient artifact "omniscient monocle" was forcibly identified as its owner by the touch of his bloody finger. This golden finger gave him the ability to see through the cause and effect of all things, and to understand human weaknesses and hidden history.
Lu Zhenhai, the richest man in Jiangcheng and the president of the underground antiques chamber of commerce, is an ambitious and power-hungry man who attempts to completely control the lifeline of the city by collecting various artifacts left behind by the people. When Lu Zhenhai's greedy tentacles reached out to Meng Yi's peaceful teaching life for the monocle, a secret battle of wits quietly unfolded in the daily tea drinking, teaching, grocery shopping and cooking. Meng Yi does not cultivate immortality or fight bravely. He only sets up serial killings while talking and laughing. Killing with a borrowed knife, information cocoon, and psychological games, Meng Yi uses the entire city as a chessboard to play with those high-ranking power chasers in the palm of his hand. This is a story about a gentle scum who uses his brainpower and calculations to crush everything in the most ordinary daily life.
