Cao Kun, who was blackmailed and imprisoned for his courageous actions, was accidentally bound to the "Brave Action System" on the day he was released from prison - he could get ten times the cash back for doing good deeds, and the inhumane nature of the trenches began! He collects evidence for the girl who was raped, denounces the unscrupulous property owner, uses noise to scare the vicious neighbor couple, and uses thunder to punish the arrogant owners who walk their dogs without leashes. He transforms into a messenger of justice and makes the unscrupulous people pay the price. In the process, he not only gained the sincerity of Wang Xun, the daughter of Huxiao Group, but also met the mysterious shareholder Liu Shiya. However, when Liu Shiya's dark past and the mystery of Zeng Mu's life experience surfaced, Cao Kun wrote his "brave act for justice" legend between adhering to justice and protecting people's hearts?
