In order to clear the wronged grandfather's name and fulfill his sister's last wish, Lin Wei follows the clues in his grandfather's diary and explores the secrets hidden in the Song Dynasty in Qingchuan together with the criminal investigation captain Jiang Xu. They cracked the "Seven Stars" mechanism, passed the test of life and death in the Longyin Mountain underground palace, exposed the crimes of Shen Wanshan, Li Zhe and other smuggling gangs, and vindicated their grandfather.
Subsequently, a cross-city cultural relic theft broke out, and clues pointed to the man behind the codename "Ye Xiao" and "Mr.". The two worked together to track down across the city, uncovering the conspiracy of the cross-city smuggling network and the "Shadow Alliance", and recovering the stolen national treasures and Song Dynasty astronomical instruments. Finally, Zhao Hongbo, the mastermind behind the scenes, was identified and his ambition to covet the Dragon Tomb was shattered.
As the heir to the "Tibetan Keeper", Lin Wei faces new crimes caused by the digitization of cultural relics. He unites all parties to crack down on criminal organizations such as "Long Shadow" and "Hunting Ancients" to protect the security of digital cultural relics. At the same time, she passed on the skills of cultural relic restoration, established the Chinese Cultural Heritage Inheritance Fund, and cultivated professional talents.
In the process, Lin Wei and Jiang Xu's relationship grew deeper and deeper, and they eventually got married. They work together to protect Qingchuan cultural relics and Chinese cultural heritage. When their sons grow up, they will also inherit the mission of "guardians", allowing the spirit of persistence and inheritance to continue from generation to generation.
