The Mystery of Wenyuan Pavilion: the Password Under the Ink Marks

On the eve of the special exhibition of "Thousands of Years of Culture" at the National Museum of Classical Books, the only copy of the "Sikuquanshu" "Kaogongji Notes" was mysteriously stolen, leaving only a mutilated brown ink mark in the display case. Criminal investigation captain Lu Shi intervened in the investigation and found that the traces concealed the Five Elements code, and Shen Qing, a key figure who was proficient in restoring ancient books, mysteriously disappeared.​ From the replica of Wenyuan Pavilion in the Forbidden City to the Wanjuan Tower in Jiangnan and the Guoyun Tower in Suzhou, five elements imprints appeared one after another, and five precious classics related to the "Sikuquanshu" became targets. The ancient legend of "gold hidden in mortise and tenon joints", the secret clues in Ji Xiaolan's annotations, the crazy coveting of the "Moying" cultural relics smuggling group, and the strange behavior of the museum director. Behind the layers of fog, there is a fierce collision between greed and persistence.​ When the codes are cracked one by one, the truth of the so-called "royal treasure" emerges - the real wealth is never gold and jade, but the thousands of years of ingenuity and Chinese culture contained in the classics. Lu Shi and Shen Qing joined hands to investigate the truth and not only uncovered cross-regional cultural relic theft cases, but also witnessed the awakening and inheritance of traditional culture in the new era. This is a wise dialogue spanning three hundred years, and it is also a song of justice that protects civilization.
