In 2025, deep in the Guiwei Gorge of the Western Regions, a mysterious mausoleum that combines the ancient Dian Kingdom and the civilization of the Western Regions was revealed. The once all-powerful tomb robber Zhang Ling was hunted down by the organization due to a failed operation. In order to clear his name, he accepted a mysterious commission, but was pursued by well-equipped armed forces on the way.
In a multi-party game with archaeologist Lin Xia and traitor Zhao Yang, Zhang Ling discovered that the tomb was not only filled with deadly mechanisms, but also concealed the secret of the "Eye of Underworld" that can control life and death. Strange beings such as the Bronze Key, the Seven-Aperture Exquisite Liquid, and the living dead tomb guardians have appeared one after another. The murals in the tomb hint at the cruel truth that the priests of the ancient Dian Kingdom used human sacrifices in exchange for immortality.
When Zhang Ling finally reached the core secret chamber, he found that the "immortal" in the coffin had long been turned into mysterious corpses. The real location of the Eye of Underworld pointed to by the sheepskin map was fatally related to the transnational tomb robbing group "Zhu Jiuyin" and the hypocritical cultural protection organization "Lampkeeper". Under the dual crisis of agency collapse and force encirclement and suppression, Zhang Ling must make a choice between human desire and the curse of death, and the end of this adventure is quietly opening Pandora's box that changes the world structure...
