You are an otherworldly demon, selected to rebirth on Gu world from Reverend Insanity. If you haven't read the webnovel to chapter 2334, this won't make much sense.
You start with 24 points by default and are encouraged to conquer the world, defeat the Venerables and deal with heaven's will. They'd certainly come for you eventually, given the boons you'd have.Ordinarily, you'll be born at the same time Fang Yuan is, 15 years before the start of the story. If you don't intervene, Fate War will happen in about 40 years. The venerables will revive shortly afterwards and wage war for dominance. There is only one timeline, inclusive of all time travel.
Perks are contained in five categories. Pick one category: perks within are half price, drawbacks provide double points.
These options allow you to buy extra preparation time, you'll be born before Fang Yuan.
Meanwhile, Shadow Sect has just been founded. They aren't the world-spanning leviathan of Fang Yuan's era, a hundred thousand years later. It might be possible for a gu master to defeat them and loot their vast reserves of knowledge.
You may select which of the five regions/two heavens you emerge in for free.
You are guarunteed to stumble upon or find clues that will successfully lead you to one of these inheritances, once your foundation is strong enough to digest the gains. The rank 5 inheritance will be fastest to attain while the others will emerge later.
These are special Immortal Gu that have transcended the limit of gu world, it is as if they were the apex masterpiece of a venerable. Only venerables could make them from scratch, while great grandmaster attainment in their path is needed to advance them past rank 6. They appear in your aperture the moment you open it, potentially destroying it unless you have a special physique or Desolate Aperture. They are fully fed and won't need food for 30 years.
You do not suffer tribulations, instead you periodically receive batches of heaven path dao marks. Without a method of refining these heaven path dao marks, you may briefly store them but must eventually release them as tribulations in the outside world. You can broadly control them but this control is more like the affinity a pet has for its master than real precision. You might specify whether you want them to come in the form of many weak beasts or one strong beast, energy, or other forms. However, you can't fully control your tribulation. Even so, this will be quite attention-grabbing and intimidating.
Your cultivation rank starts at rank 6, your aura is extremely strange and unknown to all but the most knowledgeable immortals. The rate at which you get heaven path dao marks increases slowly over time (about 3 earthly tribulations per year at the start) and may be further increased by bringing resources into the Overlord Aperture.
Your aperture resembles a constellation of small worlds floating in the void, growing and dying over the years. Their inconvenient impermanence is balanced by the rapid and bizarre evolution of new creatures, gu worms and even paths (as you develop your aperture). Once you have the methods and capabilities to refine heaven path dao marks, you may render some worlds permanent, control your tribulations precisely and manipulate dao mark conflict.
Heaven's will and fate cannot perceive you, in the same way that you cannot see your own eyeballs without a mirror. You also gain 2x heaven path attainment gain and your heaven path moves are stronger as this is the special physique of that path.
You seem like a perfectly ordinary human but can slowly assimilate any material, gu worm or person if you so choose.
Assimilating a gu material lets you take on properties of the selected material for your body, whether that's lightness, fire-resistance, durability... This can be quite expensive at the immortal level, it requires more material for the best results.
Assimilating a gu worm lets you own it like how a beast king in the wild enjoys the support of gu worms defending and healing it with natural primeval energy. Assimilated gu worms may very slowly ascend to become immortal gu depending on your cultivation, relevant dao marks and environment. You may still refine gu worms normally for reliable control, assimilating is just faster and costs no essence.
Assimilating a person requires prolonged physical contact, them not using any defensive moves and a stronger soul. It takes hours if they're of the same cultivation level as you, minutes if they're below by one rank, seconds if they're below by two ranks…
After assimilation they become mentally an exact copy of you, keeping their cultivation but overwriting their old attainments and knowledge. They also become Assimilation Demons.
This physique is considered innately demonic due to its potential for world conquest.
You are a human-shaped being made of starfire. Your food is star path materials, growing in quantity and quality as you advance in rank. You're from the Immemorial Two Heavens and thus unrestricted by the regional walls.
Your special ability is dao mark fusion, the ability to combine your dao marks together to produce primeval/immortal essence and amplify the power of your gu worms. This costs dao marks and reduces your celestial foundation but is more efficient than the usual 'burn dao marks for a stronger move'. As a star, you get 2x attainment growth in star path but may not pursue human path. To reach rank 9 you must instead consume the Sun whole. This is harder than it sounds.
Your inhuman physique starts tough and gets tougher. You grow larger, hotter and denser with rank and food consumption, surpassing a cubic kilometre at rank 8. Your core is especially dense and you are thus well-armoured against decapitation attacks.
You can't reproduce normally for obvious reasons and will need special gu formations to have either human or Star Demon offspring.
However your inhuman physique will provoke fear and hatred among those who see it – thus the 'Demon' moniker.
You may impersonate any other species for aesthetic AND functional purposes (the physical and special abilities of said beast), provided you've personally observed them for a few hours. Your transformation attainment rises slightly when you impersonate a new being. However your impersonations are limited to mortal-level or your rank, whichever is higher. You are still fundamentally human and restricted to human lifespan.
When under pressure to perform, your effective attainments fall dramatically. While you can do fine work alone, you would never be capable of developing Reverse Flow Seal or Heaven Always Leaves A Way Out For People while under attack. Don't bother going to refinement competitions either, or refining rank 9 gu in battle.
Pre-prepared and trained killer moves work fine, you still know what you're doing. Just not when you need it most.
You may purchase attainments here, special intuition about a chosen path that you immediately possess upon rebirth. If you select Great Grandmaster + it means you are one of the rare few with the talent to reach supreme grandmaster on your own without any special methods like Primordial Domain. However, learning things the hard way still uses up enormous amounts of time and resources.
Heaven, human and dream path cost 2x
You gain enormous skill and natural talent at taming and raising beasts, even without enslavement methods. With effort, you may coordinate and synchronize with them in battle as if they were trained sheepdogs. This scales with enslavement path attainment and doubles attainment growth. Beasts will also fight harder for you.
You get 1000 years of instinctive experience for long-term strategy and operational manoeuvres. This doesn't directly enhance your personal combat power, it lets you lead armies and plan wars at near-optimal efficiency. Whatever combat power you have is used with great efficiency.
You can adjust for new information, minimize risk and model the reactions of others to achieve maximum gains at minimum cost. The more factors are in play, the stronger this ability becomes. However, strategy is dependant upon good information. While you'll automatically prefer robust plans and attempt to account for unknowns, you can still lose if sufficiently surprised.This ability scales with your wisdom path attainment, becoming massively superhuman at supreme grandmaster.
