the fiendcelestial will be the cause of the end of their universe (which is inside dao creator, who makes moves on his disciple Fang Liang to reincarnate into him. This becomes a huge contention and struggle as Fang Liang becomes the heavenly emperor alongside Ji Xianshen during the empire's fall. Anyways, the prophecy missed the part that it's a primordial, and not a regular fiend, which is even higher than the fiendcelestials who are the race born at the beginning. The primordial fiend is only hypothesized because the fiends went extinct pretty much wiping each other to evolve into the primordial. Pangu, a fiendcelestial, returns, and Han Jue puts the blame of the prophecy on Pangu lol, takes his axe from a birthday event, and even takes one of Pangu's reincarnations as his disciple. It's like a Laplace factor where they are born with immense strength.
Anyways, alot of shenanigans happen, with the factions and the people above, known as sages, who control the situation and planned to reset the universe. Han Jue becomes stronger, makes his own dao, '3000 Dao'. Han Jue goes even higher bloodline to the origin to allow his son Han Tuo to be born, who then becomes the assumed prophecy figure (but we realize his son is actually pretty weak lol despite being born the highest cultivation recorded at birth in the star universe). His initial career is under the heavenly emperor's new multiverse empire as a general, and they go on to capture worlds. On a side note, his second son Han Huang's primordial power relies on syphoning Han Jue's origin universe qi to power him up, making him a battle maniac, which is like disappointing for a priomordial. His second son Han Huang was born a sage and is misognist and racist, believing his birth as a priomordial means that he is above all living beings except his family (which is like dumb bc his dad gives the bloodline to him when he evolves into the origin). His youngest daughter Han Ling can create like 10 million copies of herself to fight lmao
Anyways, Han Jue realizes the universe they live in is actually a minature universe of Dao creator in the chaos, space with multiverses and space, which is a true 'universe' level being owned by 9th chaos. Dao creator was actually an outcast who failed to become independent, and universes attract like black holes, hence why Pangu and Dao ancestor fought because they would absorb the other. Much of the story is about the sages who uphold the integrity of their universe world, but they're weaker and depend on Han Jue later. Sage level is like a big deal and an entry level true god of a miniature universe, like Nuwa who created the humans, but they're not universe owning beings. Btw, these universes are within the chaos owned by 9th chaos, who's the main mastermind and villain that is trying to absorb any competitors and revive his brothers, and his son is the deacon/guardian.
Earth is from the 8th chaos, who's dead, and Han Jue is a candidate picked by the blank domain and gives it form. 9th chaos fears Han Jue after a certain pt because Han Jue is technically not a being of domain, meaning he is indepedent and can't be controlled. 9th chaos turns the whole multiverse and all infinite space, including his fam and disciples, against Han jue, who defeats them all and ascends to the tier 0 of being blank domain, who at the end mentions that Han jue likely suceeded because there was no other candidate that lasted that long cultivating at base.
The barrier of his mountain is actually the most overpowered part of the story because it stops outside interference and can mindcontrol beings by putting them there, this actually allows Han Jue to fight against 9th chaos control and all his other enemies who try to dig information about him.
The story ends with Han Jue finally achieving immortality and seeing if there will also be someone who will one day surpass him, cue a descendent of his. Oh yeah, his 4th son gets really good at spreading his genes bc his cultivation couldn't match his siblings. Kinda sad, but his daughter and first son, who become the 'strongest' fighters, kinda just rely on his father's origin power when they run into Han Jue's universe and claim as a power bank. Han Jue didn't care and mainly used those universes as an experiment.
