The protagonist, Lu Guan, is a complete "wisdom madman". He has no system, no martial arts skills, and he doesn't even make a fortune by farming. His only advantage is strict logic and observation of micro-expressions (knowledge of modern behavioral psychology) that transcend mortals. The refreshing feeling of the whole book comes from "when everyone is still troubled by Machiavellian logic, the protagonist can see through their fears and desires at a glance." He broke through one dangerous situation in the court after another, and every time he calculated the opponent's conspiracy to death, and used "conspiracy" to kill the "conspiracy". This is a purely cerebral suspense and strategy novel.
