Guankou's Ling Hua is drinking tea with his classmate Da Qiao Konai. After the two broke up, Ling Hua, who walked home alone at night, suddenly heard a strange sound of "clicking" behind him. ...

The next day, Ling Hua's body was found-only the upper body was left.

There is a terrible legend circulating nearby: after sunset, there will be a woman without a lower body on the railway overpass, and she will make a "crack" when she moves.

Click, click, click, click, click, click, click, click, click, click, click, click, click, click, click, click, click, click.

One night, the necromancer also appeared in front of Kenai. Kenai tried his best to escape, but fortunately he managed to escape. But Kenai immediately thought that his life was still in danger within 72 hours, so he went to the library to find information about this legend and seek ways to save it. In the library, Kenai met his cousin Hirayama Rihui, who was studying psychology at the university. Richard is writing his graduation thesis about these legends. Richard told Kenai that the necromancer was related to a woman who committed suicide by lying on the track in Jiaguchuan City, Hyogo Prefecture. When Kenai heard about it, he immediately took Richard to Kakogawa.

Kenai and Ricoh came to a local university in Kakogawa. Under the introduction of Ricoh's tutor, they got to know the experts in this field-Professor Hang Fang and his assistant Abe, and learned more details. The woman who committed suicide lying on the railroad track was named Reiko Kobayakawa Kashima. After her death, a memorial tablet was built at the scene of the incident, and Reiko Kobayakawa's sister went to drink every day. However, this sister died in the Hanshin earthquake, and the consolation monument has collapsed, so no one cares.

In the year of the earthquake, people began to find strange half-length bodies. Kenai and Li Hui believe that the tablet of consolation is the key to solve the affair of the half-length necromancer. They soon arrived at the location of the comfort monument, but in front of them was an abandoned factory building with no trace of the railway. After contacting Abe, the two discovered that they had mistaken the place name. The time limit of 72 hours is coming, but can Kenai escape the legendary spell? !
