Lu Qingping, a young man from a mountain village, was captured by the remnant soul of a demon ten thousand years ago. He accidentally activated the ancient spiritual treasure Xuanyuan Tower and suppressed the remnant soul of the demon. From then on, the young man embarked on the road of cultivating immortality, scheming and using each other with the devil, fighting wits and courage, and drifting between immortals and demons.
The demonic energy of the Akiguan Continent has revived, the spiritual energy has dried up, and it is about to enter the Age of Ending Dharma, and a disaster is about to come. As Lu Qingping grew up, he gradually took the initiative. In the process of scheming with Lao Mo, Lu Qingping gradually learned about Lao Mo's past and sympathized with his experience. When he had the ability to get rid of the old devil, he kept him.
As the relationship between the two deepened, the old devil Mo Wuxie was gradually impressed by Lu Qingping's personality charm, and he willingly helped him and imparted his experience and knowledge to Lu Qingping without reservation. Lu Qingping reciprocated the favor and took the initiative to help Mo Wuxie find the remaining soul and help him reunite his soul.
Lu Qingping finally understood the law of "demon" during the battle with the leader of the Immortal Alliance. Demons are not born, but caused by the human heart. If the mind is upright, the devil will become the Tao; if the mind is evil, the Tao will also become the devil.
After killing the leader of the Immortal Alliance, Lu Qingping collected the fragments of the boundary stone, repaired the broken seals of heaven and earth, drew a clear line between humans and demons, and ended the thousand-year dispute. He took Mo Wuxie to hide from the world and practice cultivation, and finally ascended to heaven and attained the Great Dao.
