Nine Hells Bronze Gate

After his grandfather's death, veteran Chen Mo is drawn into a millennia-old conspiracy by a half-roll of Warring States silk manuscript and the cryptic warning "Seven-star Corpse Cocoon, do not approach, do not covet." Teaming up with history prodigy Qin Feng and mechanism master Lin Yue, he embarks on a perilous journey to uncover the immortality secret of the "Star-Gazing Clan." From the Qinling Corpse Cocoon Tomb to the South Sea Guixu Mirror, from the Cloud Summit Bronze Tree to the Mobei Twin Tombs, and through the Wuxia Hanging Coffin Array and the Kunlun Ice Abyss, the trio deciphers treacherous mechanisms while building trust amid life-and-death trials. They must also navigate the Secret-Keepers, the Heaven-Seizers, and foreign forces coveting supernatural technology. As the truth unfolds, they realize that the so-called immortality is a cruel experiment stripping away senses and humanity; the Seven-Star Observatory is not a treasure but a seal imprisoning seven "non-human" test subjects, and their own bloodlines are deeply entangled in this tragedy. Ultimately, before the Changbai Mountain Bronze Gate, they forsake illusory power, choose to seal the truth forever, and become silent guardians of history's secrets in their own ways.
