In the modern world, Chen Ye, the ace of the killer organization "Blood Blade", was betrayed while performing his final mission and was injected with neurotoxin. When his life was dying, he triggered the mysterious ancient bronze talisman and accidentally traveled to the prehistoric world and possessed the orphan of the Xuantian Sect. After awakening the memory of his past life, he discovered that the remnant soul of the ancient demon lord was sealed in his body, and he also had a unique bloodline of chaos.
In order to take revenge and explore the truth about time travel, Chen Ye relied on the cold methods of the killer in his previous life to integrate the forces of casual cultivators, established the "Dark Night Pavilion", and launched a fierce confrontation with the Righteous Alliance. During his training, he accidentally inspired the power of chaos in his bloodline. When he broke through the golden elixir, he even triggered the ninth level of heavenly tribulation. The remaining soul of the demon king took the opportunity to seize his body, but was counterattacked by Chen Ye with the power of chaos. Taking this opportunity, Chen Ye devoured the soul of the Demon Lord and obtained the complete "Nine Nether Mysterious Secrets". However, his whereabouts were exposed and he was surrounded and suppressed by the Immortal Sect.
In order to protect his best friend Shen Qingyue, Chen Ye broke into the three major sects alone and used forbidden techniques to wash away the whole place. However, due to excessive use of forbidden techniques, the foundation collapsed. On the verge of death, he was rescued into a secret realm by a mysterious old man, and learned that he was actually the reincarnation of an ancient power, with a "source of chaos" sealed in his body that could subvert the three realms. In the end, Chen Ye combined the power of his past and present lives, and in the final battle, he used the Chaos Source Seed to kill the incarnation of Heavenly Dao, reshape the ancient laws, and establish a new cultivation order with Dark Night Pavilion as the core.
