Austin is reborn and sees through the forbidden oath of magical siphoning secretly implanted by his younger brother and mentor. Instead of enduring endless cultivation, he gives up and chooses to live a carefree, idle life. Unexpectedly, he awakens the Starry-Sky Slumber Oath, a divine pact that makes him stronger the more relaxed and unmotivated he becomes.
No matter how desperately the villains try to force him into action, Austin effortlessly foils their schemes—even while asleep. At the Holy Grail Tournament, he shatters the forbidden oath and reveals the overwhelming power of the stars.
When creatures from the Abyss invade, Austin puts on a mask and secretly protects the city. Ironically, his younger brother becomes obsessed with the mysterious hero behind the mask, never realizing that the person he admires is Austin himself.
When the truth is finally exposed, his younger brother falls into darkness and leads an army on a path of revenge. Austin, however, puts down the ensuing rebellion with nothing more than a casual gesture.
At last, he steps onto the stars, ascends into the boundless cosmic sea, and is crowned the Supreme God of Sloth.
