决战机关城
In the early years of the Republic of China, the Aoi family in Japan has been plagued by a curse for generations. To change their family's fate, Aoi travels to China in search of the legendary Lu Ban Axe. Upon learning of this, Xu Mochen, Chu Han, Zhou Dasheng, and other descendants of the Five Dragon Seekers prepare to stop Aoi from entering the underground palace. However, they are repeatedly threatened by Aoi's subordinates, Tia and Hu Jiu, and obstructed by the Four Ghosts of Mount Li. To better protect the cultural relics, Xu Mochen and his companions follow Aoi into the underground palace, a century-old, immortal, and exquisitely crafted place. It is here that Xu Mochen and his companions begin their battle with Aoi.
