Lin Yuan, a professor of folklore, passed through a book called "Wenwen County Chronicle" and became the editor who was destined to die in a strange way. In this world, you can't point at mountains, otherwise they will collapse; you can't keep water, and there will be water ghosts if you keep it; when you hear someone calling your name at night, you must never look back. Facing the monsters all over the world, Lin Yuan found that he had a folk taboo map in his mind that would automatically update. When his colleagues kowtowed to the river god and prayed for blessings, he stared at the red and purple divine realm on the map and fell into deep thought - it turns out that the so-called gods are the biggest "source of pollution" in the world. When all the red lines on the map pointed to the magnificent temple, Lin Yuan understood that his task was not to record, but to clear.
