The lingering sound of the sermon in Zixiao Palace has not yet dissipated, and the black mist of the Beiming Demonic Abyss has spread over the ancient land. Lin Xuan, a modern monk, accidentally traveled through time and brought with him the fragments of the Hongmeng Purple Qi and the incomplete Kung Fu "Tai Xuan Sutra", and fell into the most intense chaos of Taoist and demonic disputes - surrounded by demonized ferocious beasts. The secret rift between the two factions was secretly growing, and the Demon Lord's power was quietly reorganized. A weak person like him would have to struggle to survive between the demonic energy and the sword's edge when he first opened his eyes.
A different kind of prehistoric world, this is a passionate journey of mortal monks in the chaotic world of prehistoric times, resisting demons with a righteous heart, integrating factions with tolerance, and surviving in the cracks to becoming a guardian of the prehistoric world.
