Due to global changes, cities have been dragged into restricted areas one after another.
Knocks at the door in the middle of the night must be opened, people who are called by their true names will disappear, and returnees are never allowed to land... Faced with inviolable rules, ordinary people can only struggle to survive.
However, in an accident in a restricted area, ancient book restorer Shen Yan awakened the incomplete ancient book "Record of Mountains and Rivers Gods" left by his father.
Repair the broken pages, find divine contracts, fulfill last wishes, and ask gods.
While others are still looking for loopholes in the rules, Shen Yan has already invited the door god to control the house, the city god to listen, Mazu to pilot, and the Nuo god to drive away evil spirits, and rewrite the rules under the jurisdiction of the gods and at a heavy price.
But he gradually discovered that disaster did not come naturally.
An organization called the "Anonymous Society" is erasing names, places and history, trying to wash the mountains and rivers of Kyushu into a blank page.
And his father, who has been missing for twelve years, may be one of the earliest writers.
The rules require all sentient beings to bow their heads.
Shen Yan opened the remaining scroll and asked only one question:
"Who made this rule?"
