"Poor orphan" Lin Jin received a mysterious inheritance: the ancient house at No. 13 Oak Street in Fog Town.
At the end of the letter, written in blood, he warned him to abide by three rules:
• Hear footsteps in the attic? Hide in the closet and count your heartbeats silently, ignoring the call of your dead mother
• Butlers wearing red gloves to deliver meals? Turn off the lights, hold your breath and pretend to be dead. Don't touch the "human map" under the door.
• Can't see yourself in the mirror? Immediately recite Rule 1, even if the frame is covered with rule poison ivy
When he discovered the truth about the code, the contamination had penetrated deep into his bones——
• His right eye turned into a wriggling insect pupil, and he could see regular threads and control everything.
• His blood turns into eclipse ink, and new rules are automatically generated where he writes.
• His memory was torn apart: the so-called poverty-stricken childhood was actually a cognitive prison created by the ancient house
In order to destroy the source of pollution "Law Lord", he must solve the mystery of the Möbius chain:
• The aunt with the silver knife in the freezer was once a "carrier" of voluntary sacrifices
• The blood words solidified in the stopped clock point to the Law Lord's only weakness
• And he himself is the final heart-eater destined by the chain
