Primordial: Invincible Domain From Day One

Transmigrated as a disembodied soul into the primordial wilderness during a beast calamity, Xuan Mu should've died instantly—no body, no spiritual roots, no hope. Instead, he awakens an "Invincible System" that grants him an unbeatable domain. The catch? It only covers a small area. To conquer the primordial world, he must wait a century for his domain to expand. In a realm where immortals measure time in eons, what's a hundred years? But when ancient powers start knocking on his mountain's door, Xuan Mu realizes that even invincibility has its limits.
