On his first day at Dingshengxuan, Lin Wenbin, a treasure-appraisal prodigy, uncovered a scam in which a shady expert falsely claimed the old man's Kangxi blue and white vase as a fake and attempted to buy it at a low price. He stuck to his original intention and exposed the truth in public, but was fired in retaliation from his boss. After leaving his job, Lin Wenbin refused the temptation of high salary from unscrupulous merchants and relied on his professional skills to carry out public welfare treasure appraisals. He accumulated a good reputation and accidentally uncovered the shady story of the cross-regional counterfeiting chain headed by Wang Kun. In the process, he gained the support of Zhou Qiang, Su Qing, Professor Zhang and other allies, received full support from his parents to prepare the studio, and also attracted the upright assistant Li Mengmeng. Faced with a series of retaliations from Wang Kun's forces such as threats, rumors, and pressure, Lin Wenbin was always fearless to fight back, and finally joined forces with official forces to gradually master the evidence of the villain's crimes, and move forward firmly towards the goal of completely eradicating industry chaos and protecting the rights and interests of ordinary people.
