Offer a savior to the infinite world!

Tanjiro sat in his seat a little stiffly. He looked around, tried to hold back, but couldn't help but came up to Lin Yi and asked him curiously.

"She is busy with something, so she hasn't come with me yet."

Lin Yi answered casually, but what he said was not actually true. The personal system assistant is bound to the savior. Since Lin Yi is here, Iino Miko is also here. But for some reason, the AI ​​girl seemed reluctant to show herself in front of other saviors, so Lin Yi found an excuse to smooth things over for her.

"I see. I'm a little curious about what Lin Yi's personal system assistant looks like. Will it be something special? Although I've seen quite a lot of special things today..."

Tanjiro showed a slightly regretful expression, but quickly shifted his attention away from this matter and began to sigh quietly.

After all, for this young boy who has lived in the mountains since he was a child, there were too many new and strange things he saw today, all kinds of people and things he had never seen before and could not even imagine, which made the young boy a little confused about the directions.

Countless worlds and countless people gathered here.

So, can I find a way to cure Nezuko and turn her back into a human here?

And how to become even stronger, so that you can stand in front of the enemy that must be defeated, and defeat the demon king named Muzan Kibutsuji.

Although I have been practicing full concentration breathing recently, and I can feel my improvement in the learning process, but I am only at the fifth of the lower moon, and I am already in a desperate situation. If I want to challenge Muzan Kibutsuji who is above the Twelve Demon Moons...

Jingle Bell--

The sound of wind chimes rang out again.

The door of the shop was pushed open, and a middle-aged man with a spiky hair, who looked a little listless, walked into the shop yawning.

"You're back early again, you bastard."

The blindfolded woman sitting at the counter looked at the man and spoke unhappily.

"Ahahaha, sorry, sorry, let's talk about that matter later. After all, it's rare for someone to come to me for help."

The hedgehog-haired uncle smiled embarrassedly, then walked directly towards Lin Yi.

Looks ordinary, just like an ordinary person.

However, both Lin Yi and Tanjiro could feel that this uncle, who looked to be in his thirties or forties, seemed to have a strange, indescribable aura, which was obviously not an aura that ordinary people could possess.

"Lily of the Valley, you're here again. So you're the newcomers this time?"

Pulling out a chair, he sat down next to Lin Yi and Tanjiro in a casual manner. The man smiled at them very friendly, and the expression on his face seemed a bit naive for some reason.

"As for me, I am considered a savior with some experience. I have been through some battles, so I have accumulated a lot of experience."

"When Linglan first became a savior, she didn't understand many things, so I taught her a few things. After that, whenever she met a new savior, she would bring him to me and ask me to help answer some of his questions. After all, the personal system assistant can only tell you the rules of the system itself, and the experience in the mission can only be known by those who have experienced actual combat."

"Alright, alright, don't be nervous. There is no difference in status between us. We all believe in the oath of the Savior System and decide to fight for it. Well, you are Lin Yi, and you are Tanjiro, right? Suzuran told me your names."

"As for me, my name is Kamijou Touma. I'm almost 40 now, so you can call me Kamijou-san, uncle, or store manager."

A middle-aged man with a gentle smile and a slightly unshaven beard looked at Lin Yi and Tanjiro and spoke in a very casual manner.

Interlude 1-08: The significance of mission levels

Kamijou Touma, the A-rank savior.

Since joining the Savior System and becoming a Savior, he has completed a large number of difficult tasks. He is very famous in the entire 17th Universe Quadrant and even in other Universe Quadrants. He is a Savior with a large number of followers.

There are so many stories and versions of what this savior accomplished, with truth and falsehood mixed together that no one can make an accurate judgment. The only thing that can be confirmed is that he did save countless worlds and civilizations, and he is a genuine great hero who lives up to the name of a savior.

Because of this, Kamijou Touma has a huge number of followers. Those who once fought alongside him or were saved by him even united to form a faction similar to a fan club, calling themselves the inheritors of the "will of the Phantom Messenger". Moreover, every follower particularly likes to shout at the enemy during battle, saying things like "I'll shatter your fantasies".

In response to this, Kamijou Touma himself simply said that he could not bear to look back, and said that every time he wanted to forget his middle school mentality as a teenager, these followers would force him to recall it in a vivid way, which really made him feel extremely painful.

Of course, although he said so, Kamijou Touma himself did not stop these followers from doing so. Now he is 37 years old, and after experiencing many battles that ordinary people can hardly imagine, he has entered a semi-retired state. Usually, he and his two wives run this small shop in a secluded place. His other two wives occasionally come to the shop to help, but because they each have their own business, it is usually difficult to see them in the shop.

"Wait a minute, did I hear correctly just now? His wives...?"

Lin Yi's eyes became sharp.

“Um, well, Kamijou-san… he does have four wives…”

Lily of the Valley shrank her neck and after thinking about how to explain to Lin Yi, she finally had no choice but to tell the truth directly.

Four wives in total...

In other words, is this a former palace warrior who retired after a dangerous battle?

Speaking of this kind of life winner experience, I always feel like I'm seeing the protagonist of a light novel. Is it my illusion?

"It's not abnormal to have many wives, right?"

Tanjiro, who lived in a relatively backward era, blinked, somewhat unable to understand Lin Yi's shock.

"Ah... how should I put it? It can be considered as some bad karma from the past. Okay, okay, let's not expand on this topic. Let's talk about business."

Kamijou Touma coughed lightly, showing a somewhat embarrassed expression and quickly changed the subject.

At this time, the only waitress in the store, a one-armed girl named Kobe Haruka, brought Lin Yi omelette rice. Lin Yi ate while continuing to listen to Kamijou Touma talk.

In short, Kamijou Touma rarely participates in savior missions nowadays. In his spare time, he is always happy to play the role of a teacher, answering various questions for newcomers who have just joined the system and become saviors. At the beginning, Suzuran came here by accident and learned a lot of useful knowledge from Kamijou Touma, so she brought Lin Yi and Tanjiro to this store.

"In short, if we start with the most basic things, it must be the classification of the levels of the rescuer missions. Linglan should have explained this to you two in advance, and your system assistant will definitely explain it. However, the system's own explanation is only based on the professional terms of the mission itself. When it comes to the corresponding mission, you really need to pay attention to the explanation of what each different mission level means. The system cannot tell you this. Only rescuers who have experienced it can know."

After taking the tea handed over by the blonde girl with an eye mask, Kamijou Touma looked at Lin Yi and Tanjiro with a serious expression.

There are three categories of combat mission levels, totaling sixteen levels. This is a unique classification level for the main mission of the Savior System. It is key information about the mission world that the Saviors can obtain in advance. Lin Yi and Tanjiro already know this.

The fluctuation level represents the degree of manifestation of the danger to civilization, the disturbance level represents the impact of the savior's appearance on the danger to civilization, and the hazard level most directly represents the combat strength of the danger to civilization. The fluctuation level is simply [how many people in the civilization know about this danger, and how high is the overall level of awareness of this danger], and the disturbance level is [how the different strategies of the savior taking aggressive or cautious actions will change the difficulty of the task itself], and the content of these two levels is mainly here.

Among them, there are five different levels of volatility, namely:

Hush level, the most troublesome, is the level of fluctuation in the entire affected civilization where no one is aware of the danger to civilization. In this level of mission world, the danger itself is either hidden very deeply, so deep that it will not reveal any traces, or it has some kind of mental pollution ability and has already infected all members of the entire civilization.

Each Silent-level mission is extremely difficult and extremely difficult to complete. It often takes a lot of time and energy for the Savior to confirm the mission that poses the threat, and the failure rate of missions at this level is also high. Even if the Savior System can calculate the most suitable Savior and send additional personnel when the calculation is wrong, it often faces the situation where it cannot find and destroy the threat to civilization in time, resulting in irreversible consequences.

"In other words, the system calculations still make mistakes sometimes?"

Lin Yi extracted the key points from Kamijou Touma's explanation.

"Well, the rescuers calculated and dispatched by the rescuer system are usually rescuers who can [solve the crisis]. Under normal circumstances, although they may encounter certain difficulties and dangers, they can basically complete the mission. However, in some extremely difficult tasks, especially those with extremely high difficulty, this calculation is at risk of failure. In order to deal with this situation, the rescuer system will send new rescuers to participate in the mission at any time to remedy the situation. However, in more extreme missions, even the remedial measures may still fail."

Kamijou Touma answered very calmly, obviously having anticipated such a question.

"I can indeed feel that in the previous mission, the enemy's combat power was basically matched with that of Tanjiro and Suzuran, and there was no situation where the gap was too outrageous. But is it necessary to send out a savior with combat power that is just enough to solve the problem? Wouldn't it be better to just send a savior with overwhelming strength to complete the mission?"

After pondering for a moment, Lin Yi raised a new question.

"This is a question that the Savior System is often asked. Well, there are various explanations, but in my opinion, the system wants to avoid situations like the Deus Ex Machina, so it is set up like this."

Kamijou Touma smiled, his expression showing a little helplessness.

This is not the first time that the savior of civilization has been worshipped as a god.

It saved civilization from danger that it could not resolve on its own. Such a savior who came down from the sky and disappeared directly after solving the problem was indeed like a god to civilization itself.

For individuals, this may not be a big deal, but if it is magnified to the scale of civilization, it can easily lead to hidden dangers.

In the distant past, in order to ensure the efficiency and quality of the mission, the savior system would indeed send saviors who were far stronger than the mission difficulty to complete the mission. However, the deeds and traces of power left by the saviors who solved the dangers like gods could easily lead the spiritual, cultural and technological fields of the saved civilization astray. Whether it was the blind fanaticism or extreme theocracy among the whole people, or the technological development deviation and bottleneck caused by the traces left by the saviors who were difficult to understand or even not harmonious enough with the rules of the universe, the civilization that should have been on the right track after being saved fell into new troubles.

Especially after knowing the reason for the arrival of the god-like savior and understanding that "as long as civilization falls into irreversible destruction, someone will come to save it", the bottom line of civilization development will begin to become easier to break, so that the savior system will have to send saviors to the same civilization again and again, to clean up the mess caused by the civilization itself, which is so rotten that it is simply unbearable.

Moreover, the same troubles apply to the rescuers who carry out these tasks. They are used to solving problems overwhelmingly, and every difficulty they encounter is not worth mentioning. Once an emergency situation really occurs and they need to face enemies and crises that are equal to or even stronger than themselves, the quality of these rescuers will obviously decline a lot. As a result, the rescuer system suffered considerable casualties in a crisis.

Under such circumstances, the system gradually began to adjust its strategy, so that every mission the rescuers participated in would be very dangerous to themselves, requiring them to concentrate and seriously solve the problem, or even do their best to complete it. In this way, the system ensures that the combat effectiveness of the rescuers will not decline, and they can also accumulate useful practical experience to improve themselves. As for the rescued civilization, they can see the frustration and suffering of the rescuers, and have the opportunity to fight side by side. Sometimes the rescuers even have to rely on the power of the disaster-stricken civilization to complete the task. This can truly show the rescuers [as a living being with flesh and blood], which can effectively avoid blind worship. In addition, because the rescuers' own power level will not deviate too much from the difficulty of the task, there is no need to worry that their legacy will cause deviations in the development of civilization.

And after making such adjustments, the savior system made further adjustments. That is, after completing the savior mission and leaving the universe of the rescued civilization, the savior can never return to that universe, thereby completely severing the connection between the two parties and allowing civilization to develop normally without being affected by the savior.

"That means I can't go back to check on Lillian and Mr. Bob?"

After hearing this, Tanjiro couldn't help but reveal a somewhat regretful expression.

"Well, yes. The more missions you complete and the more obstacles you experience, the more you want to go back and check on them. This idea is understandable. However, this behavior is essentially a secondary disturbance to civilization. Even if it seems to be a small and harmless action, it may cause adverse effects. Therefore, the saviors must never go back to a civilization that has been saved and can continue to develop on its own. Because that civilization no longer needs their support."

Kamijou Touma nodded gently, answering the boy's regret and taking a sip of tea. As for Lin Yi, he had already eaten all the omelette rice while Kamijou was talking, and was wiping his mouth now.

Anyway, let’s get back to the topic of task level division.

The remaining four difficulties of the fluctuation level are Hysteria, Phantom, Seuche and Canceration. The dangers to civilization in these difficulties range from almost weird legends to long-term fierce confrontation with the entire civilization. The degree of exposure gradually increases. Basically, the rescuers can find a way to lock on the root cause of the danger to civilization and take action. Compared with the Hush level, there is basically not much to say.

It should be noted that the level of the fluctuating mission actually represents the difficulty level of the rescuer's intelligence collection. The difficulty and danger level represented by this level are basically the opposite. The lower the level, the more difficult the situation faced by the rescuer is, and the harder it is to find clues. Therefore, in low-fluctuation missions, the most important thing for the rescuer is to pay attention to everything that may be wrong and do his best to find all the violations, so that he has a chance to find the right path.

"Then, regarding the disturbance level, this is a level that is difficult to explain. Even if the system assistant explains it to you, it may be difficult to understand what it means. However, this level can also be explained more intuitively. Let's put it this way. The disturbance level represents the intensity of the reaction of your enemies and the civilization hazards that you need to solve under the actions of the saviors."

Different civilizations face completely different hazards. It could be a meteorite from outer space, a super volcanic eruption, a nuclear war that destroys civilization, or an alien invasion.

When the rescuers intervene in these hazards, the intensity of the reactions presented by these hazards will naturally have different levels. The rescuer mission classification is to provide the rescuers with information in this regard.

The lowest level, Drop, is like a drop of water falling into the sea, leaving no trace at all. This type of civilization hazard is basically very stable, just like explosives that can only be detonated by special devices. Even if thrown into a fire, it will only burn normally and will not change much due to external forces.

The Wave and Tide levels above will have corresponding intensity reactions under the interference of the rescuers. The Tide level reaction has the possibility of increasing the hazard level, and there is a danger that the combat effectiveness will change and the rescuers will not be able to resist, so close attention is needed. This point was actually clearly reflected in Lin Yi's first mission. After all, because of the appearance of the rescuers, Sheriff Rest couldn't help but kill them the next day. As a result, the fight between the two sides turned into a decisive battle. This is the situation revealed by the disturbance level.

And, at the end of the disturbance level, there is a level called Tsunami, which is a special level. Saviors generally do not encounter this level of disturbance missions.

Well, it’s not that tasks at this level are extremely difficult, that has nothing to do with it.

By the time a mission of this disturbance level is discovered, civilization has basically been destroyed and the mission can no longer be carried out.

After all, this level means that even the savior system may not be able to take action in time, and the magnitude of the change in the civilization hazard itself is completely beyond imagination, so that the affected civilization is directly destroyed before the savior arrives. This type of civilization hazard is like a violently reactive compound, and it does not even require an external disturbance source such as a savior. Just some unconscious actions of the members of the affected civilization itself will cause the hazard itself to change at a very high magnitude, and it can even ignore the savior system's ability to control the universe's space and time and destroy the affected civilization.

As for the final level of hazard, this is very simple and clear. It is just the level of combat effectiveness.

There are seven levels of hazard, the most basic Spark level, and the more advanced Vlam level, Ladder level, and Ekhi level. You don't need to know the higher levels now, because they are still too far away from you. In short, the difficulty of the Spark level has been seen in your first mission, and the next Vlam level is likely to be the level you will encounter in your second mission. As for the last two levels, if you have the possibility of greatly improving your strength, you may have the opportunity to see them at that time. Of course, this will have to wait until the second mission is over and you pass the inspection.

"Investigation? In other words, we are not yet officially part of the Savior System?"

Lin Yi asked the question again.

"Yes, the Savior System has a very precise selection method that can ensure that all the people selected are brave enough to save others. However, it cannot be ruled out that there will be some people with completely twisted minds who will do evil with good intentions."

"Even though we have improved the accuracy of screening many times, this situation is still unavoidable. Therefore, the first two missions that the Savior System sends to new Saviors are actually for testing purposes. This is the final test to determine whether you can join the Savior System."

Kamijou Touma's expression turned serious at this moment.

For the first mission, the rescuer will face a low-difficulty mission with a small-scale impact, and the mission must be performed in a civilization with normal overall order. The system uses this to examine the rescuer's qualities in all aspects and ensure that he or she can behave normally under normal circumstances.

In the second mission, the savior will definitely face a world with distorted order or collapsed order. In such a world, the system will examine the actions taken by the savior and the changes in his or her ideological state when the moral order has completely collapsed, and examine the savior's own [bottom line].

Kamijou Touma did not directly say this, but just said that Lin Yi and Tanjiro just need to complete the task in their own way. In fact, there is really not much to worry about. Being able to get the system assistant and qualify to arrive in this community after passing the first mission proves that both Lin Yi and Tanjiro are saviors recognized by the system without any problems. If there was a problem with the first mission, they would not be able to get their own personal system assistant and come to Kamijou Touma. After all, the system's requirements in this regard are not particularly high, and generally no one will fail.

Well, if I remember correctly, there has only been one person who failed the inspection mission in the past five years. It seems to be a magician named Emiya Kiritsugu? Or is it a magus? I don't quite understand the naming rules of that universe.

"Anyway, any questions?"

Kamijou Touma took another sip of his tea, looked at the two people in front of him, smiled, and then asked.

"Well, I kind of wanted to ask about teamwork and non-emergency missions."

Lin Yi thought for a moment, and remembered some words that Linglan mentioned at the end of the previous mission, so he looked at the uncle in front of him and spoke again.

Interlude 1-09: Preparation and Body Shaping

It was already afternoon when I returned to the universe where I now lived.

Lin Yi stretched and looked at his room in the hotel. There were bulletproof vests placed on the bed, several grenades, a survival dagger, several talismans with strange patterns, and a small bottle that emitted strange light, like some kind of potion.

These are some props Lin Yi bought from the Savior Community for the second mission. Bulletproof vests are a kind of soft, special close-fitting clothing that can withstand continuous shooting from submachine guns at zero distance without penetrating the clothing. Of course, although it can prevent it, the impact will definitely make people feel very painful. The grenade is divided into two fragmentation bombs, two stun bombs and two incendiary bombs to deal with different situations. The survival dagger is simple and straightforward, and it is a very sharp blade. It can play a good role in combat self-defense or dealing with various situations.

As for those strange spells, they were purchased by Lin Yi after selection. These spells can produce effects to remind oneself when encountering malicious energy reactions, can also be thrown out to automatically search for enemies and attack oneself, can also ignite and burn by themselves to create a fire, and are a multi-purpose disposable supernatural item. The small potion bottle is called [Holy Grail Blessing], which is said to be a weakened version of something in a certain world, which can heal physical injuries after drinking, and there are many flavors to choose from, such as strawberry, mango, and watermelon.

In addition, Lin Yi also modified the gun he obtained in the first mission world. This modification was done by a weapon dealer who called himself "Duke" in the G-level trading area of ​​the Savior Community. To be honest, when Lin Yi first saw the fat-like weapon dealer, he really couldn't believe that this guy was capable of weapon modification. But the fact is that this man only took a short time to do a very good modification and maintenance on Lin Yi's gun, and it can even be said to be a replacement-level modification.

Come to think of it, is it reasonable that the trading zone has level restrictions?

Lin Yi's current savior level rating is F-, which means that it exceeds G level, but there is still a level lower than the normal F level.

Therefore, in the trading area of ​​the Savior Community, he can only enter the G-level trading area, and cannot go to the F-level and above trading areas. This is probably the system to prevent Saviors from directly obtaining high-level props that are convenient to use, and killing through low-level tasks in the manner of Master Fengling Yueying? In short, after spending a little money, Lin Yi has comprehensively updated his equipment, and it is no longer in the blank state at the beginning.

By the way, all the money was spent on lily of the valley.

In addition, in the Savior Community, Lin Yi also found a variety of service assistance that could be obtained, including a renovation construction team that could cross dimensions. Considering that the original renovation team took too long, it would take more than two months to complete the house renovation. Lin Yi hired this construction team to work together with the previous one.

It is known that it takes sixty days for Construction Team A to complete the construction alone. It has already worked alone for two days. It takes fifteen days for Construction Team B to complete the construction alone. Now the two teams are working together, and it will take... cough cough, why is my brain going to strange places for no apparent reason?

In short, by the time he returns from his next mission, the construction here will be completed smoothly and he can move in normally.

And, what has not been mentioned before is the frequency of the rescuer's mission. For regular rescuers, the mission frequency is once every 20 to 40 days. The specific duration and mission start time can be determined by the rescuer himself, and then the system arranges and determines the final suitable time.

Although according to Iino Miko, when the savior's mission begins, the flow of time in the universe where the savior lives will almost stop, and then after the mission is over, the savior will be healed of all injuries and put back into the original universe. Therefore, for the universe where the savior lives, the savior himself has never left. But after all, for the savior himself, carrying out the savior mission is a very mentally exhausting thing, so in this regard, the system gives a lot of flexible time arrangements, so that the savior can ensure that he can participate in the mission in the best condition.

Lin Yi set the time to twenty-one days. In the universe where he now lives, every twenty-one days, he will participate in a main task arranged by the system.

As for the rescuer's personal team and non-emergency tasks, these are not the focus of attention now, so Lin Yi did not pay too much attention to them.

"So, the summoning candle, three modified pistols, 60 rounds of spare ammunition, bulletproof vest, dagger, talisman..."
