Zhang Yao saves people but is slandered. He accidentally activates the truth system and can sue unfair incidents with one click. Litigation fees are waived and he can earn justice points to exchange for rewards. He started by prosecuting blackmailers, and successively raged against bosses who exploited employees, domineering neighbors, and malicious competitors. With the support of the system and his own wisdom, he fought lawsuits, expanded contacts, and took control of the company. He counterattacked from an ordinary worker to the president of the group. He also gained two sincere emotions. He used the law and truth to protect justice and wrote a passionate counterattack legend.
