Museum security guard Zhang Hengchuan touched a bronze coffin while sorting ancient books, and accidentally activated the devouring system - which can devoure the target's cultivation, treasures and even relationships by killing, burying corpses, fulfilling other people's last wishes, etc. In order to trace the truth behind his family's extermination twelve years ago, he was involved in the "Nine Coffins Bureau" tomb robbing mystery: every time an ancient coffin is opened, a suspenseful event that overlaps with the mirror image of history is triggered. In order to find the missing archaeologist father, cold-blooded photographer Lin Chaoyan and Zhang Hengchuan formed the "Coffin Swallowing Team". When the two of them solved the "Blood Coffin Curse" and "Mirror Abyss Maze" and other ancient tomb crises, they gradually discovered that the hypocritical antique dealer "Mr. Chen" was the mastermind behind the situation - he attempted to resurrect the long-annihilated "Yin Dynasty" by devouring the cause and effect of past tomb robbers. Zhang Hengchuan relied on the "Dragon Seeking Technique" and "Corpse Dissection Technique" devoured by the system to uncover the dual truths of the "Nine Coffins" and the family's destruction layer by layer in 400 chapters, and finally ended the Yin Dynasty's revival by devouring the villain's cause and effect.
