Su Yuan used the world invitation, it seems that it is still a world invitation made by Gaia and Alayya, and it has been explained on the invitation that after use, the next mission world will be locked in the type moon - fate/zero, that is, the fourth Holy Grail War in the type moon world.

When it comes to the Holy Grail War, it is natural to mention the Heroic Spirits, Servants, and Magicians.

What is a Heroic Soul? The spirit of heroes, in the past history of mankind, in the ethereal myths, can be called the existence of heroes, they have made famous achievements in their lifetime, and after death, because of human beliefs, their own merits, and legends, they were reborn as heroic spirits after signing a contract with the world, breaking away from the timeline and coming to the outside of the world, not belonging to the past, not belonging to the future, not belonging to the present, independent of the seat of the heroic spirits outside of time.

When the world has a need, it will summon the Heroic Spirit from the Throne of the Immortal, and when others have a need, they can summon the clone of the Heroic Spirit, that is, the Servant.

In other words, the world can summon the Heroic Spirit, and the other beings can summon the clone of the Heroic Spirit, that is, the Servant.

Of course, the Heroic Spirit itself is naturally able to resist the call outside the world, and the Servants who appear in obedience to the summon have different powers from the Heroic Spirit itself, and some are even simply clones with power, and they will disappear directly after completing the task.

Speaking of which, the Heroic Spirit is equivalent to Gaia and Alayya's thugs, after all, there are so many things happening in the world, it is impossible to let Gaia and Alayah personally take action in everything, right?

Magicians, the power system in the type of moon, a group of people who explore the root vortex, continue to study magic for the root vortex, and for the root vortex, the so-called demon path was born, that is, ......

As long as we can reach the root cause, at all costs, by any means, we can ignore the law, we can ignore humanity, we can ignore morality, we can have no bottom line, everything is to reach the root.

If this generation can't complete it, then the task will be handed over to the next generation, and if the next generation can't complete it, it will be handed over to the next generation.

All the magician's means and research are aimed at reaching the roots, and what is produced in this journey is magic and magic.

Magic is equivalent to a skill, and the results that this skill can cause can be completed with the current technology of human beings, just like using magic to release a small fireball, and using scientific and technological means to create a small fireball, the two are essentially different but the result is the same, then this means is called magic.

Naturally, magic is the ability to create phenomena that are absolutely impossible to accomplish with the current technological means of human beings, and this ability is called magic.

From ancient times to the present, human science and technology have continued to advance, and more and more things can be done, so it is natural that the means that used to be called magic have been relegated to magic in modern times, and the magic of destroying a city in ancient times has been relegated to magic now.

After all, in modern times, as long as you have money, a missile can destroy half of the city, and with magic methods, you also need to work hard to transform and accumulate magic power, arrange a magic array to absorb magic power, and then recite a long list of incantations, and finally release the magic spell, and the result is the same as a simple missile!

Therefore, with the advancement of human science and technology, in modern times, there are only five methods that can still be called magic, and all the others are relegated to magic.

The division of magic and magic is actually quite a bit of nothing to do, after all, from the perspective of the infinite world, technology and magic are just different reinforcement systems, but technology requires the accumulation of knowledge, and the aspect of the performance is also in the collective power, the enhancement of the apostles of time and space outweighs the losses, and the magic is manifested in individual strengthening.

The reason for this difference is probably that magicians look down on the relationship between the technological system developed by ordinary people, and think that they are superior, so they divide the means of magicians according to what technology can do.

In fact, if you can become enlightened, who cares what path you take? In the eyes of the Apostle of Time and Space, this is simply inexplicable arrogance.

As long as he can help himself continue to evolve, the space-time apostle doesn't mind throwing nuclear bombs occasionally, just like Su Yuan and the others gave the big snake a two-piece set of space-based weapons.

Magic is a by-product of magicians' pursuit of the root, that is, in their opinion, the most important thing is to reach the root, and everything else is insignificant, and magicians all over the world naturally use different means to reach the root.

And the Holy Grail War is one of those means.

Hundreds of years ago, in search of their roots, the Einzberen and Mariqi families came to Fuyuki City, Japan, to collaborate with the local magic family, the Tosaka family.

The leylines of Fuyuki City are connected to an endless source of magic power, according to Xiuxian, it is a huge spiritual vein, containing the majestic aura of heaven and earth, so the foreign Einzberen and the Mariqi family chose to cooperate with the Tosaka family, a magic family that manages this land.

The Tosaka family provided the land, the Mariki family provided the method of summoning the Servants, and the Einzberen constructed the Holy Grail system.

These three families are known as the Gosan family.

The three of them collaborated to create the Holy Grail War in Fuyuki City, and the Holy Grail War that claimed to the outside world that 'the victor can get the Holy Grail to fulfill his wishes' was actually a Holy Grail War that existed for magicians to reach the roots.

The magic circle located in the Enzo Mountain in Fuyuki City, that is, the Great Chalice system, absorbs the magic power of the leylines, stores this magic power, and uses it to carry out the Holy Grail War, and it will take about sixty years to store the magic power to start a Holy Grail War.

When the Great Grail system stores mana to a certain level, seven people with magical qualifications are selected to display an omen mark on the back of their hands, symbolizing that they have been selected as the prepared participants in the Holy Grail War.

At the same time, a magician with a sign of omins will need to summon a servant, after all, summoning a clone of a heroic spirit from the Constellation of the Immortal outside of independent time is not a simple matter, and the magic required is also unusual.

However, the Great Chalice system will be responsible for the supply of most of the mana, and at the same time replicate the Heroic Spirits who respond to the call and desire to exist for the Holy Grail, forming Servants who are like the Heroic Spirit Clones, but different from the Heroic Spirit Clones.

After the participant summons the Servant, the Omenmark will be transformed into a spell under the magic of the Great Grail system, which not only represents the identity of the magician participant, but also represents the balance on the Servant.

After all, the servants are heroes of all eras, so it is likely that there will be problems with the participants, so the spell is also a means used by the magician to forcibly order the slave, a spell command once, generally speaking, when the war starts, the magician will have three spells.

During the Holy Grail War, seven groups will fight each other, and it is said that the victor will receive the Holy Grail to grant all wishes.

Of course, that is only said that the Holy Grail War is a means used by magicians to reach the roots, and the so-called fulfillment of all wishes is only to attract magicians and heroic spirits.

As one of the builders of the Holy Grail War system, Einzberen will prepare a tangible Little Holy Grail before the start of the war, and the Small Holy Grail and the Great Holy Grail system are interconnected, and the soul of every Servant who dies in the war will be attracted to the Little Holy Grail.

When the Minor Chalice absorbs six souls, it will cooperate with the Great Grail System to open the hole for the return of the Servant's soul, and the magic of the Great Grail System will fix the hole, forming a hole to the root of the outer world.

At that time, through the hole, it is possible to reach the root, and as for the fulfillment of wishes...... Isn't it the magician's wish to reach the roots?

This is the idea of the magicians, if they can break through the guardians of Gaia and Alayya......

After all, the magicians don't know about the existence of Gaia and Alaye, and the most they know is what Gaia and Alaya show, such as inhibition or something......

After the Holy Grail War system was built, the Holy Grail War naturally began, but things didn't go as planned, and the first, second, and third Holy Grail Wars all failed for various reasons.

That is, there is no winner, so it is a defeat for magicians.

And this time period is still a year before the start of the Fourth Holy Grail War......

Fuyuki City, at the door of Tosaka's house.

A middle-aged man wearing a red suit, a mustache on his chin, the whole person looked clean and straight, and at the same time stood with a very elegant demeanor, with a serious face, and said softly: "Jian Tong Weng, the little girl will be handed over to you to take care of." ”

Behind the middle-aged man, there stood a woman with long green hair, who looked gentle and virtuous, and a little girl of seven or eight years old, with black hair combed into a double ponytail.

The little girl with the double ponytail grabbed the hem of the woman's clothes, and looked closely at another little girl, a little girl with black and half-long hair, and the little girl's hand was being grasped by an old man who was as thin as a dry corpse.

"I tell you! You have to take care of Sakura! Otherwise, I won't let you go! The little girl with two ponytails said loudly as she stared at the corpse-like old man.

The girl who was held by the corpse-like old man bit her lip, and a trace of disappointment flashed in her eyes.

"Rin-chan! Don't talk to him like that! The middle-aged man frowned slightly, and reprimanded softly, the little girl with a double ponytail flattened her mouth, but her eyes were still staring at the old man menacingly.

"Hehehehe, don't worry, the old man will definitely take care of Sakura."

The corpse-like old man was wearing a kimono, holding a cane with one hand, a leaky laugh came out of his mouth, and the other withered palm touched the hair of the little girl next to him, "After all, with Sakura's qualifications, it would be a pity if you didn't learn the Demon Dao, hehehehe!" ”

The girl called Sakura shrunk her head, but a smile still appeared on her cute face, as if she didn't want her family to worry.

"Then there's you."

The middle-aged man closed his eyes and bowed slightly to the old man known as Rin, followed by the woman behind him and the little girl with a double ponytail known as Rin, but Rin still raised his eyebrows at Rin, making a silent threat.

"Cute little girl, hehehehe."

The old man let out a goosebump-like laugh, and then pulled Sakura away slowly, Sakura looked back as she walked, and finally her face was full of loss.
