As the saying goes: the south is the way, the north is the fairy, and the Hu Huang cannot cross Shanhaiguan. There has always been a very strange "out-of-horse fairy" in Northeast China. According to legend, there are five major immortals: "fox, yellow, white, willow, and gray". The five immortals will reward favors and avenge enemies, which is called "protecting the calf" in Northeast China. Therefore, the five immortals are also called "guardian immortals". Out-of-horse immortals are people who have a connection with the immortals. They are worshipped for generations and can communicate with the immortals. They use the power of the immortals to cure diseases and save people and do good deeds. The immortals and out-of-horse immortals usually sign a contract and live and die together. Among the five guardian immortals, Hu San Tai Nai of the fox family is the greatest, with the strongest magic power and the most loyalty. During the Republic of China, it was rumored that Majiatun in the deep mountains of Northeast China had always been blessed by Hu San Tai Nai. However, some villagers went up the mountain for money and stole the ancestral tombs guarded by the Hu family for generations, dug out the fox den, and angered the fox fairy clan. After that, all kinds of strange things began to happen in the village. Men in the village died tragically one after another, and women were humiliated and abused. The village invited a fox spirit to perform a ritual. All things have spirits. Which is scarier, the fox spirit or the human heart?
