The Human Race Is in Decline? I Return a Million Years to Create a High-Martial Arts System

In an era of high martial arts, countless races stood side by side. Humanity was weak, reduced to slave labor and livestock for blood, barely clinging to life. When Xu He’an suddenly awakened memories from a past life, he opened his eyes to a living hell and watched his loved ones die at the hands of alien races. At the brink of despair, he activated the Primordial Simulator. It could simulate the world a million years ago and take him back to humanity’s primitive age! Here, the wilderness was untamed and the myriad races had yet to rise! While the alien races still had no idea how to grow stronger, Xu He’an had already passed down martial arts techniques. While the alien races thought precious mineral veins were nothing but rocks, Xu He’an had already sent people to mine them and forge peerless divine weapons. Origin arts, poison arts, Gu techniques, mechanisms, formations... Xu He’an traveled back and forth between two eras, using his knowledge of the future to benefit primitive humanity, and his simulations of the past to shape the future. With his own strength alone, he forged a high-martial system for humanity that spanned the ages! And when he returned from his final simulation, as the timelines converged... He opened his eyes to find all the races bowing their heads, and humanity reigning supreme!
