Before starting with the clarifications, if something is written in parentheses it is a note from the author.
Well to put this into context... those of you who know me will know that I've tried and failed to do a full story of this sort at least five times... probably more since I had a previous Wattpad account deleted, and I always end up cancelling it for one reason or another mostly because I rarely really follow a fixed timeline but this time and after somewhat perfecting my author's bible for this story I'm at least partially confident that I'll be able to finish this story, though to make things easier on myself I'll keep the clarifications pretty basic yet comprehensive this time around.
That being said, let's get started with them.
Number one and most important of all this is a Naruto Multicrossover story with main emphasis on Fate series and Fairy Tail, where this is not the typical Naruto emperor, well he is in part since he ends up becoming the emperor of the entire world for something the title of "the first emperor" since for those who know me for a long time will know that this was one of the first fics I did, I think it was something like the fifth being one of those that in my lore are known as the five founders, and being one of the four kings of legend. However unlike other Naruto who have the fate of the world on their shoulders and the damn hero complex or do it for a dream, he simply did it only because he had no other option, he did not want to be king on the contrary he wanted a simple and quiet life however he had two things against him for that, number one he is extremely powerful so much that he can match in strength beings like Gilgamesh basically at 46 plus where he was in his prime, with Qin being only 21 years old and surpass him if the fight becomes one of resistance, by the time he turned 30 he was basically already indisputably the most powerful being in the world being in fact the Jade Emperor himself from Chinese mythology, and the second thing he had he would literally find destiny that for veterans already know that he is the "father king of all legends" that is to say whether he wanted it or not he was predestined from birth to be the father of all legends. (except for the Uruk who in canon are the only ones capable of fighting against fate and winning) the point I want to make is that he does not want to be king but he has to because it is what is expected of him, and since he does not know anything else he will give 100% of his effort and determination to be the best king he can be.
Number two: and this is not so much about the plot as it is about his children, and that is that honestly I find it tiring to play him the emotionally abusive father that he is in the current version given my own experience with my mother and her constant denigrations to me and my older brothers, that's why this time instead of being emotionally abusive (he constantly calls them disappointment one and disappointment 2 for those who don't know) this time he will only be distant but accessible, he will not show them affection he himself thinks that he is not capable of showing that kind of love since although he knows how it feels he does not have a father figure to ask advice and in his own words "I prefer to keep them at a distance but safe and happy, than to be in their lives and make them suffer from not having a father who loves them" ironically showing how much he loves both of them.
As for her relationship with Mordred who as you know is "her" favorite daughter, the thing is simple, although Arty is not nearly as much of a bitch as in canon (literally calling her Morgana's spawn depending on which version of Arturia we're talking about, right Lancer) this time she simply reacted to the news (given many years before Morgan could start his plan to take over Brittany) with a simple "I... need time to get used to the idea that I have a son... one of which I am the father and not the mother" put another way their relationship although quite complicated is not bad, but with Qin it is quite close, to begin with this time they will not be even remotely the same age as they are in the current story in fact their ages are.
Arturia: 27.
Morgan: 23.
Naruto (Qin) 21.
Mordred: 5.
Making Qin the age of a typical teenage mother and allowing her to better identify with the one who is in every way but blood related to her daughter, both being the unwanted child (although in Mordred's case it's more of a failed experiment for Morgana, and for Arty it's more of a situation he still needs to get used to)
Number 3: If the second one was extremely long I know, but well this time I will follow a plot very similar to "Unified Eastern Empire" with notable differences of course and I will list them below in order of importance.
1. Nobody is nerfed like in that story each and every one of the characters that will appear in the story have their full power level, meaning legally beings like Superman, Thor, SHAZAM among others effectively have the power to destroy the planet with a single punch (obviously I'm not using their most broken versions, I mean Superman Prime and Old King Thor are power beasts that are more like the Uruk level more specifically Lancer almost rivaling the tomato), and another like Gilgamesh oh surprise have the ability of true gods, not to mention Arturia who literally either you are a god and you surpass her in power in an absurd way or you lose to the "bearer of the sword of promised victory" and if that is the only reason why she can't beat Gilgamesh he is simply the most powerful servant of all even the divine class servants, but besides him she would basically destroy any other servant without many problems if she was not limited.
2. I'm giving a few buffs to some characters, such as Yujiro Hanma, who I'm basically making a Toji on steroids being the first user of celestial restriction in known history in my lore, plus some others since as it is said in all my stories of this kind. "even the weakest civilian in the outside world is stronger than an average chunin from the forbidden continent" and Yujiro being one of the ten kings of heaven is one of the strongest beings in the world (before you say no, being king of heaven does not imply being part of the top 10 of existences, Qin is the strongest and is not in the group for being the emperor, the same as Karna who equals Gilgamesh in power as well as Enkidu, being celestial king only implies that they have the complete trust of the emperor and have an authority in the empire only surpassed by the emperor himself)
3. There is something that particularly bothers me about two of Naruto's emperor stories, and that is that he hides his identity for some reason that I have honestly never understood, I mean if he were the leader of a small nation I would understand but he leads an empire of beings that could easily bring the entire shinobi continent to its knees individually, obviously he has no real reason to fear, and that is something that I will not do although people refer to him as King Qin, this is because his title is literally "first emperor of Qin" translated into Spanish, his name is and always will be Naruto Uchiha and it is by this title that those closest to him refer to him to show their closeness, while the rest will call him King Qin or failing that Majesty, but he will not hide his identity under a mask because that would be giving up his pride which is something he would never do under any circumstances since in his own words "I forged in blood a kingdom of peace and prosperity, with the strength of my arms I broke the chains of those who were oppressed and brought them freedom, in the name of the people who have honored me as their king no I'm going to commit the cowardice of hiding from a past that I left behind long ago."
4. Unlike my other stories where he has the soul of Kyubi inside him, this time he doesn't have it, his only maternal figure is and always will be Mikoto Uchiha, this has two main purposes, number one in all my stories I always leave the Kyubi aside after the first five chapters and unlike a certain author whose name I will not say out of respect for my childhood and his memory, if I am going to include a character directly related to the protagonist I will at least give him a little prominence and not leave him forgotten, in other words, Kyubi will not have much relevance in this story, and number two and this has to do with the second nickname "father of Sorcery"
5. As he is the father of sorcery itself, that means one thing he is not able to use chakra because his body was created to be perfect for sorcery, and not like Sukuna who literally had to become a monster to reach his level, Qin on the other hand being the father of the arts of sorcery is literally unsurpassed in them (at least in his time being the one who invented them and therefore who documented their restrictions, then came Satoru, Sukuna and the tomato who literally broke the limits of sorcery known in their time) that being said he created simple domain, total control techniques, barrier techniques, he was the first known user of a cursed technique, and the first known user of a domain expansion and reality bubbles, (for more context on this ask G0J0 he is the one who made the lore of the reality bubbles and domain expansions) as well as inverted ritual. But we will move on to his combat abilities later now let's continue with the clarifications.
6. This is the least important of the plot clarifications, and that is that unlike "Eastern Empire Unified" where he takes Tayuya and Karin with him, this time he is going completely alone since to begin with Tayuya is not a redhead, she is a pinkhead, the anime simply made her a Bulma and changed her hair color, ergo she is not Uzumaki and even if she were, Naruto does not consider himself an Uzumaki, (if Bulma in the manga has purple hair, hence Trunks also has purple, the reason for his blue hair is simple, Toriyama ran out of purple ink for a cover and people liked her better with blue hair, and if that happened why did he start drawing her with blue and purple hair randomly to see which style they liked more and ended up staying blue) as for Karin, it is basically more of the same, he does not know her and frankly speaking he has no reason to help someone he knows because his idiot stepbrother accidentally saved her from being devoured by a bear.
And well, that would be all the clarifications of the plot without counting his countless lovers and wives, now let's go with his combat skills, don't worry I won't go into too much detail about them... I didn't even believe that myself.
Very well to start with its most important feature of all, its eyes, these unlike the eyes of the "Qin Shi Huang of Shumatsu" these are much more powerful, having several truly formidable characteristics.
Eyes of the king.
First, the most important of all, is that they are the reason why he can use cursed energy being that they have the innate ability to absorb the energy of negative human emotions and allow him to use it as a source of energy intrinsically superior to chakra in offensive power but inferior to magic in versatility, and to the cosmos in destructive power (not that the latter matters much because he can use cosmos at Gold Knight level) the only downside the eyes have is that they cause damage to his body, hence why he invented the reverse ritual because it was something he needed to not die by the action of his eyes.
The second ability of his eyes is more directly related to the realm of combat and is one that he can activate at will (when his eyes turn red) and that is the ability to see the breaking points of living beings and the attacks of his opponents, which basically translates to him being able to see the weak points of basically any being or thing and with his unique combat style allows him to completely destroy them. (in this mode he does not absorb the cursed energy)
Hand-to-hand combat style.
Well to put this into simple perspective... his fighting style differs greatly from the original Qin's style, consisting of five styles like the one seen in Shuumatsu but being very different styles and each with its strengths and weaknesses. (actually there are six taking into account that Genbu is a snake-turtle and that would add one more variant, but meh) said fighting styles are basically these.
Chi-Yu Turtle Style. This is the most defensive style of all, being used mainly in battles that he knows will be decided by a fight of resistance. It basically consists of attrition and blocking movements, being this the style he used in the war of the 40 days and 40 nights against Gilgamesh.
Chi-Yu snake style. It is a slightly more offensive variant of the turtle style in which agile and fast movements are used to dodge the enemy's attacks, giving up the blocks of the turtle style to allow a slightly more aggressive but defensive stance.
Phoenix style Chi-yu. This is the most fluid and flexible style of all (because the phoenix is a bird and basically has the advantage of being able to fly and therefore being relatively agile) consisting of fast and agile movements, although having the downside that by completely giving up defense, receiving a blow is basically a sentence of defeat.
Tiger Style Chi-Yu. This is by far the most aggressive of the six styles, as it completely renounces defense in exchange for a total offense (hence why the White Tiger Moon Bow is capable of tearing off a piece of a god's arm).
Chi-Yu Dragon Style is the most powerful style of all by far, consisting of fast and powerful blows, but without neglecting defense, although for this very reason it is the most complicated style to use since it requires a strong body to withstand the recoil of each blow. (Interestingly, since it requires a strong body, or in the case of Qin, having to use his aggression to the maximum, it is a little more defensive than the Phoenix style)
Chi-Yu God of War. This is what is known as the perfect combat style as it blends the other five styles perfectly into a balance, it is powerful like the dragon, (on a much smaller scale of course) aggressive like the tiger, (again on a smaller scale) fluid like the phoenix, and defensive like the turtle.
Other skills:
Ritual technique: In the years after his reign (more specifically during the tomato era) his cursed technique came to be called "glory of the king" which consists of two extremely important parts.
Number one obtains the strength of a king, in other parts for each being that recognizes him as their king he acquires a little more strength (hence why it is universal scale) being basically invincible because the technique does not differentiate between present or future, that is to say even if it is in the future when being recognized as the "first king of humanity" his present self acquires the increase in power (again hence the universal power scale almost bordering on the multiversal) (yes hence even Sukuna admits that against him he has no chances simply his technique is exaggeratedly broken)
Number two, his cursed technique allows him to use or rather replicate the abilities of those who recognize him as their king, hence he is able to use the Gate of Babylon, Zeref's death magic, and the techniques of the knights and even some gods without much effort.
Reverse Ritual Technique: Again due to his tacit need to heal his body he found himself in the need to invent the Reverse Ritual Technique as he flatly refused to have to depend on an external agent to be able to command his troops into battle, and after a long time of experimentation he discovered the principle of positive energy and its ability to repair damage, although of course his technique is rudimentary compared to the current one since it cannot heal lost limbs, something that sorcerers of the current era can do.
Ability to create reality bubbles: (again for more context ask G0J0)
Total Control Technique. This is a technique developed by the Demon Hunters' Guild, but perfected by Naruto himself for those like him who are extremely broken and could accidentally break the planet in half, it consists of concentrating every minimum gram of power in a single point in order to ensure that the residual damage of any battle is reduced to a minimum and that the damage to the opponent is maximized (even so the shock waves can cause the surroundings to be almost completely destroyed if they use all their strength during the battle) this is a difficult technique to master but once mastered it is capable of being used even instinctively.
Domain expansion. This one is more complex so... ask G0J0 how it worked because I honestly don't remember.
Expert in weapons combat.
And that would be all, with any luck the... holy mother of god a thousand and one hundred words of pure clarification.
