Male lead: Pangu. Not the traditional Pangu who died after creating the world. He is either a transmigrator or Pangu awakened to his true self, knows some of the "plot," and possesses peerless potential and an unmatched origin. He is decisive and ruthless, domineering and fiercely protective, but generous and gentle toward those he considers his own, especially the female leads.
Worldbuilding: The era before Hongmeng was divided, before chaos opened, or at the dawn of the Primordial World. It includes the Three Thousand Chaos Gods, innate gods and demons, innate beings, and races born after creation. Power levels include Chaos, the Great Dao, the Heavenly Dao, Saints (Golden Immortals of the Great Firmament of Primordial Chaos), Quasi-Saints, and Golden Immortals of the Great Firmament.
Golden finger:
Ultimate origin: He is Pangu, the strongest Chaos God, master of the Great Dao of Power, with an invincible body and extraordinary comprehension.
Hongmeng Supreme System (optional): Provides missions, draws (Hongmeng treasures, cultivation techniques, divine abilities), cultivation boosts, rewards for binding a Dao companion, and more, accelerating growth and collection. Alternatively, he doesn't need a System, since he is already the biggest cheat.
Partial foreknowledge: Some knowledge of major events and famous figures in the Primordial World.
Female lead setup:
Types: Innate goddesses, reincarnations of Chaos Gods, demon clan rulers, ancestral witches of the witch clan (gender-swapped? Or a special relationship), fairies and goddesses, peerless beauties from other realms, and more.
Traits: Peerless beauty and extraordinary origins, each with her own distinctive charm and abilities, such as Nuwa's creation, Houtu's compassion, Queen Mother of the West's poise, Xuanming's icy beauty, and the essence of the sun and moon in Xihe and Changxi.
Ways of winning them over: Saving them, offering guidance, conquering them, going on adventures together, domineeringly taking them as wives (?), binding them through the System, and more.
