Behind the unknown world, there is a group of unscrupulous cannibals, who are from the inhabitants of another dimension who cannot be reached from this world, the Red Apostles.

They manifest themselves by eating at the power of human existence, causing all kinds of incredible phenomena at will, and the reason for all this is only their own selfish desires.

The strength of these apostles is beyond the resistance of human beings in this world, but it is among these apostles that there are compatriots who are aware of the abnormality. They perceive that the lack caused by the cannibalization of human beings will distort the world, and they also perceive that the continuous accumulation of distortion will bring great disasters to both the present world and the red world.

As a result, this part of the apostles, that is, the Red World Demon Kings, decided to crusade against those compatriots who invaded the present world and devoured humanity.

However, since the Red World Demon King is an extremely powerful existence, if they want to make themselves manifest in this world, they must obtain a large amount of existence power, and if they eat humans, it will be contrary to their purpose. So, after countless attempts, they selected some humans from the present world who had been robbed of their relatives, lovers, and friends, and asked them to dedicate their entire existence as a vessel to accommodate the Red World Demon King.

As a result, the demon kings were able to gain the ability to crusade against their compatriots without revealing themselves, and the humans also possessed weapons of revenge, and the crusaders born in this form of contract were called fire and mist warriors.

"Shana with Burning Eyes", its main theme is the confrontation between the Fire Mist Warrior and the Red World Apostle.

“…… Anyway, that's the basics. ”

Tang Hao spent nearly half an hour explaining the incident to Youzhu and Meiqin, as well as the worldview of this world, and after finishing speaking, he got up and moved his muscles.

Knock Knock Knock –

With the knock on the door, a young woman with a decent appearance walked in, holding tea in her hand, and then walked up to the three of them, put the tea on the coffee table, and said with a soft smile: "Uncle, I have prepared black tea for you." ”

After talking for so long, Tang Hao happened to be a little thirsty, but he took a sip and said, "Thank you, sister-in-law." ”

"Is there anything else I need to do?"

"No need, sister-in-law, you can go by yourself, don't worry about us."

"Okay, then you can talk slowly, and call me anytime if you have something." The young woman smiled kindly, and closed the door as she left.

Mai Sakato blinked and said with some surprise, "I really didn't notice it at all." ”

"It's magic, after all." Tang Hao said with a smile.

After Xia Na left, Tang Hao didn't choose to follow anyone, after all, there was no clear task this time, compared to what to do, the first thing that should be understood is what can be done. And whether it's Xana or Yuji Sakai, they are not candidates who can cut in directly, especially the former...... Because she is the heroine, she follows her directly, which may arouse her suspicion and hostility.

Anyway, according to the story of "Shana the Burning Eye", most of the events in the early and middle periods happened in Misaki City, as long as they didn't deliberately make some huge changes, such as ...... Kill Yuji Sakai, then, as long as you stay in Misaki City, there will always be a chance.

Therefore, the three of them found a room in Misaki City and stayed for the time being.

The owners of this house are a young couple with a fairly wealthy family, the husband has gone on a business trip and will not return until more than half a month later, leaving only a young wife and a five-year-old child at home.

In FZ's story, after Webb arrived in Fuyuki, he lived in the house of an old couple and became the grandson of that family, because he influenced the old couple's cognition through magic, so that he was born out of nowhere.

Even Weber, a half-assed person like Weber, can learn magic, as a top modern magician, it is naturally impossible for Youzhu not to know, so he concocted it in this way, and there is an extra brother and two younger sisters in this family.

Speaking of which, this kind of magic is really convenient, although it doesn't work for magicians or people who have magical powers, but for ordinary people, it is a quasi-use, if it is used to do bad things...... For example, in the cognition affected by magic, Tang Hao is not the younger brother of the male host, but has become the male owner himself, so ...... It's just an NTR artifact!

However, although the values of magicians are very understandable, and can even be said to be distorted, the vast majority of magicians will not have Tang Hao's dirty ideas, and Youzhu does this just for convenience.

She didn't know that Tang Hao's mind was hovering with that evil thought at the moment, carefully analyzed the current information, and then raised her head, "According to what you said, people who have been devoured by the power of existence will disappear directly from the world, and the people around them will not be aware of their existence, so why can I still remember?" ”

Tang Hao immediately came back to his senses, in the previous seal, there were three torches as human substitutes, because Xiana was going to repair the site, they were consumed, it stands to reason that the concept of these three people will disappear directly from people's cognition, and no one can detect it, but Youzhu realized that they had existed through careful observation.

"Maybe it's because we're not from this world."

Tang Hao thought for a moment and explained.

"Our perception of the world comes from the outside, and we who have not yet fully integrated into this world are like players in the game, and the local people are NPCs.

"This analogy is a bit different...... Youzhu frowned, "I don't quite understand, but I seem to understand." ”

"Wait." Mai Trin's eyes lit up, "If the humans in this world are NPCs and we are players, then wouldn't the Red World Disciples and Fire Mist Warriors be the relationship between viruses and antivirus software?" ”

"I guess that's how it can be understood...... You're pretty good at drawing inferences. ”

"What's the use of drawing inferences?" For Tang Hao's praise, Mei Qin was not the slightest joy, but a little discouraged, "We players don't have the function of anti-virus, except that you can use the second soul to be immune to the seal, the two of us have no way at all, if the battles in this world are carried out within the seal, then isn't our existence meaningless?" ”

Hearing this, Youzhu couldn't help but fall into deep thought.

Although her magic can also be performed in this world, she can't be immune to blocking, which is equivalent to losing the premise of fighting, no matter how strong her strength is, as long as the enemy casts a seal, she and Mikoto Misaka can only be slaughtered, if this problem can't be solved, the two of them will not be of any use, it is better to return now, leaving Tang Hao alone, at least don't worry about dragging him back.

"No, it's not." Tang Hao shook his head and said with a smile, "First of all, we have to understand what the seal is. ”

"What is it?"

"It is a kind of ability, which is called the law of freedom in this world, although it can affect the world, and the level of interference is relatively high, but in the final analysis, it is not fundamentally different from magic superpowers and the like, it needs enough energy to activate, and this energy is the power of existence...... In other words, as long as you find the right way and have enough existential power, even a miscellaneous fish like phosphorus can open the seal, but if you don't have the power of existence, no matter how powerful the fire mist battle is, you can't use the seal. ”

"So, the key to the closure is the power of existence?" Youzhu's eyes lit up.

"That's right, the manifestation of the Red World Apostle requires the power of existence, the power of existence is needed for the exercise of the Law of Freedom, the power of existence is needed to make the torch, the power of existence is needed for battle, and even the restoration of the environment requires the power of existence, it is like sunlight, like water, like air, like fire, like **, it is an indispensable energy source for human survival."

Mai Trito frowned, "Is there a strange thing in the energy source of human existence?" ”

"Don't worry about the small details, in short, this is what I mean: as long as we can master the use of the power of existence, we will be immune to the ban, and with our own combat power, we will be enough to fight against the Red World Apostle."

"So the question is, how do we master the use of the power of existence?"

"Well, ......" Tang Hao suddenly smiled mysteriously, then took out his right hand, and as his fist slowly opened, a wisp of blue flame continued to flutter in his palm.

"What is this?" The two stared intently.

"This is the power of existence, and it's not the power of existence in general." Tang Hao said proudly.

"How?"

"It's the power of Yuji Sakai's existence."

"Is there anything special about that?"

"What's so special...... Although I don't know for the time being, Yuji Sakai is the protagonist, in other words, this is the power of existence that enchants the protagonist's aura, and it is definitely much more advanced than the ordinary power of existence, and the SSR golden quality ......"

"But it's blue."

"Oh, why are you so sick, carrying it?" Tang Hao couldn't listen to it anymore, pinched it hard, and twisted the blue fire in his palm into two parts, and handed them to Mikoto and Youzhu respectively, "I already knew that I would face such a problem, so I specially helped you get this power of existence from Sakai Yuuji's body, and take it to study it carefully." ”

"......" Mikoto and Jiuyuan glanced at each other, dumbfounded.

Although they all understand the truth, but ...... How should this be studied?

"Will this fire burn out?"

"It should be, after all, Yuji Sakai is just a torch, and the power of existence that has been stripped away is no longer a zero-hour fan, and most of them will stay for a short time, so you must find a way to master the use of the power of existence before it burns out."

"You're too strong!" Mai Qin was a little overwhelmed for a moment, "I don't even understand the specific concept of the power of existence now, how do I know how to master it?" ”

"Aren't you a superpower, the kind with an IQ of more than 200, you still don't understand this?" Tang Hao asked rhetorically.

"Superpowers are only strong in computing ability.,What does it have to do with IQ?,One party has the strongest computing power in the school city.,Even more than a computer.,Do you think his IQ can be compared to a detective like Sherlock Holmes?" Mai Trillion rolled her eyes at him, then added, "...... Although it is true that my IQ is not low. ”

"It's worthy of being a detective comic book fan, and as soon as he came up, he used Sherlock Holmes to bully the common IQ of one side, but you are right, Jin Shanshan claims to be omniscient and omnipotent, and his IQ is not necessarily high, so it can be seen that the strength of strength and IQ may not be proportional...... "Tang Hao is either not black, and he is black.

"Of course, you don't need to be too anxious, during this time, I will find a way to intervene in the main line, as long as I can deceive Xia ...... If you have a good relationship with Xana, you will be able to ...... with Astolfo Uh, is it called Astolford? Tang Hao showed a puzzled expression when he was halfway through speaking.

"It's Alastol! The world's Catastrophe Alastol! You stupid brother! ”

Kaguya's condemnation suddenly sounded in his ears, and Tang Hao suddenly suddenly realized, "Oh yes, Alastol, he is a very awesome Red World Demon King, maybe it will be a good shortcut." ”

"Uncle, dinner is ready, you can come out and eat."

Through the door, the voice of the hostess came from outside.

"Okay, right away." Tang Hao responded, and then looked at Youzhu, "By the way, you are also the sister of this family, why does she only call me and not you?" ”

"yes, we seem to be just in passing." Mai Trin also discovered this problem.

"Because I'm not sociable." Youzhu pondered the blue fire in her hand and said calmly, "When using cognitive magic, it only improves your sense of existence, so in her cognition, we are the kind of children who have no sense of existence...... Well? ”

Suddenly, Youzhu's eyes lit up, "presence...... The Power of Being...... I seem to have a solution. ”

"What? Tell me about it! Mai Trin immediately stepped in.

Then, the two talked to themselves.

Tang Hao looked at it and found that he couldn't interject into the topic, so he got up and walked out, "Okay, then I'll go to dinner, and by the way, I will exchange feelings with my sister-in-law, so as not to arouse her suspicion." ”

"Tang Ritian, it's still live broadcast!" Kaguya's voice reminded.

"What's wrong with the live broadcast, I didn't do anything unspeakable......"

……

On the same night, under the same night sky, Tang Hao and his sister-in-law were eating and exchanging feelings with each other, while Xia Na was standing on a rooftop, looking at the brightly lit city below, faintly looking for something.

"The disciples who drove the phosphorus seem to be still in this city."

"According to that phosphorus, it seems to be a very large being, and it is not afraid of us, and there is another reason......"

"Mistis."

"Hmm."

"So, if we want to find that disciple, we just need to keep an eye on Mystis."

"Yes, but ...... I care more about the stand-in messenger than about Mystis. ”

"That guy?"

"Well, I don't know if it's an illusion, when I came into contact with him, I seemed to feel a similar aura to mine for a moment."

"Similar to yours?" The girl was stunned for a moment, and blurted out, "Could it be that he is the Red World Demon King?" ”
