Xie Xuan, a good-for-nothing abandoned by his family, unexpectedly obtained the "National Treasure Appraisal System" on the day he broke off his engagement - able to identify the true value of any item and trigger hidden plots. He originally just wanted to retire quietly, but due to a series of tasks triggered by the system, he was forced to get involved in various bizarre events: helping the grandfather to find the lost guqin, identifying family heirlooms for the square dance aunt, making antique nests for stray cats... Every time he takes action, he will get unexpected surprises. However, when he accidentally discovers a shocking secret during an appraisal, the entire world begins to change. What's even weirder is that the ex-fiancée who broke off the engagement seems to be secretly looking for the same thing...
