(Traditional fantasy. The protagonist isn't brainless, and this isn't a wish-fulfillment story. There are no jarringly contrived scenes of malicious bullying and no villains who act stupidly. The first two chapters lay some groundwork, and the story picks up from chapter three. A complete outline and detailed plot plan are in place, and it will absolutely have a proper ending!)
As the Heavenly Dao weakened, it sent down a Heavenly Dao embryo to remake the cosmos. But an Immortal Emperor coveted it, hoping to usurp the Heavenly Dao and claim supreme authority. The last guardian of the Heavenly Dao's core, Ancestor Gongsun, sacrificed himself to protect it. Using a secret art that could obscure the Heavenly Dao's aura and sever cause and effect for ten years, he sent the embryo to the human realm, into a snowy night in the southern wilderness. This faint spark was the last hope of overthrowing the Immortal Court.
Yi An, the reincarnation of the Heavenly Dao embryo, was born without spiritual roots, his path to immortality cut off. But after knocking desperately on the gates of heaven, he stumbled upon the Star-Burning Art. He stole the stars' flames to burn the Heavenly Dao and tempered his mortal body to defy the cosmos! Taking his first step from a path to immortality that had been cut short, he would spread the flames like wildfire and burn down the Immortal Court that ruled the Myriad Worlds!
