Perfect World: I Have a Primordial Chaos Body, and My Brother-in-Law Is the Desolate Heavenly Emperor

Primordial chaos blood runs in my veins; even the Desolate Heaven Emperor calls me big brother! Huo Yan transmigrates to the Chaotic Ancient Era of Perfect World, becoming the eldest legitimate son of the Fire Emperor, and the future brother-in-law of the Desolate Heaven Emperor. Gifted by heaven and earth with a flawless innate Chaos Body, he can manifest the myriad Dao of the world with his left hand and obliterate all things across the heavens with his right. He even creates a cultivation system for his own world: divide the Two Modes, open the Four Images, derive the Eight Trigrams, open the Nine Palaces, and give rise to creation. He rules the clans and Daoist lineages of the lower realm's Fire Nation, subdues the geniuses of every age in the battle across the Three Thousand Provinces, and defeats every imperial clan of the foreign lands in the battle at the Imperial Pass. Follow the natural order and remain mortal; defy it and become an immortal. At the end of the Immortal Dao, I stand at the peak!
