Once he traveled through time, Lin Fu became the standard cannon fodder male supporting character in historical novels - in order to pursue Su Qingyuan, the "evil female supporting character" in the book, he squandered his family wealth, offended the powerful, and eventually ended up being executed. Lin Fu, who had awakened his memory, looked at the marriage certificate handed in front of him, and just wanted to show his middle finger to God: This plot is broken, whoever wants to leave, whoever wants to leave! He decisively tore up the marriage contract, refused to be a licker, and turned to rely on modern knowledge to engage in "outrageous operations" in ancient times: using probability theory to calculate imperial examination questions, using marketing to sell improved farm tools, and using talk shows to resolve court disputes. He wanted to lie down and save his life, but the more he acted, the more he got out of the circle. Not only did Su Qingyuan, who was originally going to turn black, chase him, but he also accidentally got involved in real historical events such as the Jingkang Revolution and Wang Anshi's Reform. While others fought for power and profit to the death, he was busy inventing hot pot, starting a tabloid, and telling the emperor cold jokes; while others fought bloody battles on the battlefield, he used "psychological warfare" to scare away the enemy and relied on "food diplomacy" to ally his neighbors. Lin Fu discovered that as long as he didn't act according to common sense, the originally serious history would run in a funny direction. The powerful minister wants to take advantage of him? Instead, he was deceived into investing in a "milk tea shop"; the enemy wanted to plot against him? But he was confused by his "brain twists"; even the original male and female protagonists couldn't help but follow him and "not do their jobs properly". This is the story of a cannon fodder male supporting actor who refused the plot, used humor to mess up the history of Dajing, and finally became the winner in life - by the way, a reminder: Don't let Lin Fu become serious, when he becomes serious, he is more outrageous than funny!
