A fragmented map of the East China Sea coordinates appeared. Chen Mo went to find the origin of immortality alone, but he triggered a thousand-year-old murderous plan laid by the Ashes Society. This transnational organization in the name of "purifying history" is systematically destroying the fire of civilization guarded by the Immortals.
Following the clues left by Chen Mo, Lin Xia contacted five descendants of "fire bearers" from around the world who possess ancient skills: an ancient book decipherer in London, a cryptographer in Istanbul, and a lacquerware inheritor in Kyoto... The incomplete skills they each mastered pieced together the shocking truth about the Guixu Altar - which not only contains the ultimate secret of Xu Fu's eastward journey, but also is the place where civilization's survival is determined.
When Chen Mo found the inscription "The immortal needs to sacrifice all his memories to end the curse" in front of the altar, the armed fleet of the Ash Society had surrounded the ruins. Lin Xia must crack the astrological code within 72 hours and race against time before the "Civilization Reset Plan" is launched.
From the star map murals in the unopened caves of Dunhuang, to the navigation codes in the secret reliefs of Angkor Wat; from the warning bamboo slips written in blood by female historians of the Han Dynasty, to the records of secret conversations between Einstein and Chen Mo during World War II... The guardian network spanning two thousand years is finally gathering.
"This time is not a farewell." Chen Mo put Si Nan into the center of the altar, and seven bloodline induction light pillars rose into the sky, "This is a transmission."
When modern technology and ancient secrets collide in Guixu, when one must choose between personal immortality and the continuation of civilization, the answer to this battle for protection spanning the history of human civilization will eventually be revealed:
The fire never goes out, someone comes later.
Intent: The continuation of civilization requires not only the lonely perseverance of watchmen, but also the courage and choice passed down from generation to generation.
