The Primordial World has been occupied by "Outsiders from Beyond the Heavens" for thirty thousand years. Humanity has been reduced to slaves and food, civilization has been shattered, and the last surviving tribes struggle to endure. The invaders are divided into seven great clans, including the "Blood Demons," "Bone Monsters," and "Shadow Clan," each with its own eerie abilities. They rule heaven and earth. Lin Xuan, a 25-year-old graduate student in modern history, accidentally transmigrates to the Primordial Era and awakens the "Huaxia Heroes Summoning System."
