Su Mobai, a top modern paleographer and expert in deciphering historical codes, accidentally came across a mysterious character during a digital restoration of ancient Silk Road documents, and his soul traveled back to the Zhenguan period of the Tang Dynasty. Before he could recover from the chaos of the times, he learned that a group of foreign tomb robbers who called themselves "Secret Keepers" were frantically searching for a lost "Book of Heaven" in the Western Regions, claiming that it contained secrets that could "rewrite the lifeline of the Central Plains Dynasty"!
With his professional sensitivity, Su Mobai quickly realized that this "heavenly book" was anything but ordinary, and behind it might involve major historical truths that had been deliberately concealed. In order to prevent this group of tomb robbers from using the power of ancient characters to subvert the Tang Dynasty, he disguised himself as a merchant proficient in the languages of the Western Regions and embarked on the dangerous Silk Road.
The "Secret Keepers" organization has cunning methods. Not only are they superior in force, they are also proficient in ancient institutions and exotic magic. They hunt down Su Mobai who has discovered his identity along the way. From the ancient city of Gaochang to Suiye, from the desert labyrinth to the snowy mountain castle, Su Mobai has no golden finger. The only thing he relies on is the vast knowledge of ancient characters in his mind, his meticulous logical reasoning ability and his persistence in historical truth. He must race against time to decipher the secrets of the ancient scrolls before the "Keeper of Secrets" and reveal the shocking conspiracy hidden within!
This is not only a life and death game related to the safety of cultural relics, but also a text decryption that spans thousands of years, and an ultimate contest between modern wisdom and ancient conspiracy. When the secret of the "Book of Heaven" is revealed, what will be the fate of the prosperous Tang Dynasty?
