The protagonist Shen Yan is a descendant of a family of Chuma Immortals in Harbin. His grandmother is the top Chuma Immortal in the Northeast. He has all five immortals (fox yellow, white and willow gray). After his grandmother passed away, only the Gray Immortal (Grand Master Hui) followed him. He was bound to the "Chuma Immortal Sign-in System": when you sign in, you can get talismans, blessings from the Immortal Family, and incense points. The incense points can be used to upgrade the hall, unlock the transformation of the Immortal Family, and summon the Immortal Family to fight.
The setting is completely in line with the folk custom of Chuma Fairy in the Northeast: The upper body of the fairy family depends on fate. The more incense the stronger the fairy family. The Chuma Fairy saves people not for money but only for incense. The evil spirits are divided into four levels: lonely ghosts, evil corpses, evil spirits, and foreign evil cultivators. The higher the level, the more difficult it is to deal with.
