Liu Dali, a young brick-moving expert in modern times, was accidentally hit on the head by a steel bar. When he opened his eyes again, he was transported back to the body of a poor boy with the same name in the early Tang Dynasty. Before he could digest the fact of time travel, a thing that claimed to be "the most powerful face-slapping system in the Tang Dynasty" bound him.
"Ding! It has been detected that Wang Laowu next door despises the host's poverty, and a slap-in-the-face mission is issued: Wang Laowu is willing to give ten copper coins. Mission reward: a gift pack for newbies."
"Ding! It was detected that Fatty Zhang, the silly son of the landlord, was laughing at the host for not having seen the world. A slap-in-the-face mission was issued: use 'advanced' knowledge to render Fatty Zhang speechless. Mission reward: a Dali Pill (temporarily enhances physical strength)."
"Ding! It has been detected that the county magistrate's brother-in-law is bullying others, and a slap-in-the-face mission is issued: make him embarrass himself in public, and realize that there is "someone out there". Mission reward: elementary fighting skills."
From then on, Liu Dali relied on the blessing of the system and the "whimsical ideas" brought by the modern soul to start a fancy face-slapping mode in the land of the Tang Dynasty. From the countryside to the county town, from the marketplace to the court, he fought against bullies, teased powerful people, and mocked corrupt scholars. He gained fame, wealth, martial arts skills, and even accidentally alarmed the Khan... See how the simple (and wrong) Liu Dali flourished in the Tang Dynasty, slapped him in the face, and reached the pinnacle of his life!
