In the first year of Qianlong's reign, a Ming Dynasty ghost ship entwined with gears and luminous jellyfish appeared on the bottom of the South China Sea, and strange coded songs were heard every night. The timid and fearful Dr. Su Yan of Qintian Prison accidentally deciphered the early warning of "the East China Sea Earthquake in March" and was forced to get involved in this battle involving imperial power, Western Mechanicism and cultivation sects. The night he boarded the ship, he touched the ancient bell, and images of his past life emerged deep in his memory - and the Ming Dynasty singer Li Guang, who had merged with the ship's spirit, was using her singing to maintain the crumbling cracks in time and space. When the young Heshen approaches with the rampage system from the future, when the truth of the "Dragon Vein Compass" is revealed - it is not a treasure, but an anchor to suture the wounds of history. Steam gears turn the astrological compass, deep-sea songs calibrate the broken dimensions, and a countdown to the survival of civilization quietly begins under the appearance of a prosperous age.
