Xiao Yi, a copywriter from a third-rate advertising company, unexpectedly became popular during a bidding process - his casually scribbling plan was impersonated by his boss, and he actually won the best creative award of the year. However, soon after, the plan was accused of plagiarism and the company fell into crisis. The boss shirks the blame in public, the partners are in trouble, and the competitors are even more pervasive. Just when everyone thought he would be ruined, Xiao Yi discovered that he had a special ability: he could see the hidden logical chain behind the incident at critical moments and crack all scams and lies. From the advertising circle to business wars, from workplace positions to capital games, this seemingly harmless little copywriter used his trump cards and counterattacks to tear apart the masks of hypocrites with his own hands. And this popularity is just the beginning of his entry.
