Long Yuan Breaks the Evil Record

On the cold river in the twelfth lunar month, a cowhide map hiding the mystery of his grandfather's disappearance led Lu Yan and his friends Zhao Hu, archaeological expert Professor Su, and the voodoo girl Qinghe to Longyuan Island in the lower reaches of the Songhua River. This isolated island where evil spirits are said to be inhabited hides the magical underground palace of Yeon Gae Su-moon, the King of Goguryeo's witchcraft. The four of them crossed the river and encountered a whirlpool, and managed to escape with the help of black dog blood, poisonous insects and explosives. After landing on the island, they broke through the thousand-year blood vine blockade and broke into the cave covered with witchcraft runes. In the cave, there are arrays of stone figurines and swarms of corpses. The ghost of Yeon Gaesumun uses the black energy to cause trouble, and is full of murderous intentions. The four of them each showed their strengths and worked together to break the situation. They went through many dangers through life and death, and finally broke the core of the underground palace, burned the evil medium, and completely eradicated the millennium evil. They also revealed the truth about Grandpa Lu Yan's sacrifice to prevent the resurrection of evil, and ended the curse of Longyuan Island with courage and justice.
