Zheng Mo, nicknamed "Viper", is a talk show actor who relies on his talk and IQ. At the instigation of a friend, he participated in an online truth or dare live broadcast, but was secretly tricked by his former friend Zhao Ming. He was exposed in public and had a dark history. The live broadcast room became a street rat that everyone wanted to beat. However, he did not expect that this seemingly ordinary game was actually bound to a mysterious system - the "Truth or Dare System". Every time you complete a game task, you will be rewarded, and if you fail, you will be randomly punished. What's even weirder is that he found that the memory fragments he lost actually overlapped with the system task content. In order to retrieve the truth, take revenge, and uncover the larger conspiracy behind it, Zheng Mo used his poisonous tongue and IQ to fight his way through the live broadcast industry, while using the system to engage in brain-burning games. What he doesn't know is that behind those "truthful words" there are shocking secrets that can destroy the entire human society.
