Chu Chen, an ordinary college student, fell into a mysterious valley while rescuing his classmates while mountaineering. He accidentally awakened the ancient Tianyan bloodline and was involved in the undercurrent of the world of immortality. While inheriting the ancient skills, he also shoulders the important task of purifying the evil energy of the Nine Netherworlds and guarding the balance between the two realms. However, the fluctuations of bloodline awakening alarmed the Jiuyou Sect dormant in the shadows of the city. This evil cultivator that summoned demons and devoured living beings was eyeing him.
On the way to practice, Chu Chen met Su Qingyao, the cold and arrogant heir of a cultivating family, Chen Mo, a cynical roommate who hid a secret, and Nangong Yue, a rebellious girl who was a demon cultivator. Together, they worked together to explore the truth about their bloodline and launched a thrilling confrontation with the Jiuyou Sect. From the life-and-death fight in the underground black market, to the conspiracy traps of the sect trials; from exposing the collusion between the Su family and the Jiuyou Sect, to competing for the four-image magic weapon that can change destiny, Chu Chen grew up in crisis after crisis. But when he realized the power of reversing time and space, he found that a bigger conspiracy was sweeping... In the collision between the modern city and the world of immortality, can Chu Chen protect the people he loves and rewrite the future that is about to collapse?
