In an unknown space, communication that cannot be heard by outsiders is going on in secret.

A voice that couldn't tell the difference between a man and a woman echoed in an unknown space: "The intruder took advantage of it, and he came to Fuyuki City early as an assassin. ”

Another voice asked, slightly puzzled, "In the Fuyuki Holy Grail system, the Assassin Rank Agent summoned through conventional means will only come from the Assassin Order, how did the invaders bypass this restriction and descend on the Assassin Rank?" ”

"I don't know, but this is good news for us, compared to the upper three knights, the ability of the Assassin is relatively weak, and it shouldn't be too difficult to deal with the threat of invaders."

The other voice was silent for a moment before retorting, "Not necessarily, you can first look at the inherent skills and treasures given to him by the rules of the world." ”

“……”

“！！！”

"Is this person really a modern human?"

There was a long silence in the unknown space, and after a long time, the being who spoke first sighed softly: "We can't let the invaders destroy the fragile balance and stability of this world. ”

"Send a coordinator in the name of the Holy Grail to unite the participants involved in the Holy Grail War as much as possible, persuade them to eliminate the invasion of the advent before they start fighting each other, and give the participants a certain reward to stimulate their enthusiasm."

"But who should we send as a referee to join the Holy Grail War?"

"Considering the intruder's inherent skills, let's send that holy woman out in a targeted manner."

"No objections."

……

The secret calculations of the two existences, Lu Xiao didn't know anything at this time.

This way of entering the new world made him a little unaccustomed, in the past, the system would release the world quest before crossing the world, and inform him of the name of the world in advance.

It wasn't until Lu Xiao officially landed on the earth that the system, which didn't know what he was doing before, released the world mission in hindsight.

"The One World Mission Released - Overcome the Tough Obstacles and Win the Holy Grail War."

Lu Xiao: "??? ”

"Gone? What about the rewards? ”

System: "Depending on the total number of Servants defeated by the host, the rewards given after the completion of the task will fluctuate, and the host chooses whether the lottery wheel or points are required." ”

"Okay." Lu Xiao sighed helplessly: "To put it bluntly, I only drew a big cake, and how much I can eat in the end depends on my performance, right?" ”

After the task is released and Q&A is completed, the system enters the pretend dead state again.

Retracting his divergent thoughts, Lu Xiao turned his attention to the little master in front of him.

This very delicate-looking little lady is dressed in a rather elaborate dress, and she is about 6-8 years old.

Judging by the way she dresses, this little girl should have a good family condition and upbringing.

Facing Lu Xiao, who suddenly appeared in front of him, he still tried his best to show a calm attitude...... But her trembling body and the tears in her eyes revealed what she was really thinking.

"Hey~"

Taking off the hood and squatting down, Lu Xiao tried her best to keep her eyes level and look at the girl in red.

"Little lady, are you my master?"

"You...... You ......"

Seeing that the other party was speechless under the nervousness, Lu Xiao smiled and stretched out his hand on the other party's head to gently soothe.

"Don't be nervous, take a deep breath first, think back to the family education you usually receive, you shouldn't want to embarrass your family, right?"

This sentence seemed to hit the key point in the other party's heart, and the little girl with two ponytails took a deep breath and finally suppressed the tension.

"My name is Rin Tosaka, and I set up a magic array to summon heroic spirits, but ......"

Rin Tosaka looked at the formation patterns drawn randomly with chalk on the ground, she just tried to vent under the pressure of depressed emotions, and she didn't expect the summoning ceremony to really succeed.

'Rin Tosaka? ’

Lu Xiao's eyes froze, and she looked at the little girl whose tears had not yet dissipated.

The iconic double ponytail and stubborn character that does not admit defeat have a big age gap with the UBW chapter, but I can still vaguely see some outlines after 10 years, and I can't be wrong. ’

It has been several years since Lu Xiao watched the full episodes of Fate/Zero, and although the general main plot is still remembered, some of the details are very vague.

This time, the system didn't give Lu Xiao time to review the plot, and hurriedly threw him into the new world, and Lu Xiao couldn't recognize Rin Tosaka when he was young for a while.

Lu Xiao looked back at the chalk magic array that still had traces on the ground, and the corners of his eyebrows were slightly raised, but he didn't say anything about it.

"Then, I'll call you Rin."

Gentleman Lu Xiao stretched out his right hand and put it in front of the young Rin Tosaka: "Rin, can you show me the back of your right hand?" ”

Under Lu Xiao's reminder, Rin Tosaka remembered his father's teachings, and put his right hand in Lu Xiao's hand with his head held high.

"You want to see the spell, right? Come on, that's proof of my mastership. ”

The young Rin Tosaka's spell has not changed significantly from when she participated in the Five World Wars ten years later, it is still a two-layer semicircle as the main structure, and the bright red spell is engraved on Rin's delicate and white skin.

"The contract is officially formed."

Lu Xiao stroked his chest with one hand and half-knelt in front of Rin Tosaka and said solemnly: "Master, I will win the Holy Grail War as your sword, what wishes do you want to achieve through the Holy Grail?" ”

Rin Tosaka subconsciously opened his mouth to say something, but considering something that happened recently, Rin Tosaka, who was less than 7 years old, failed to say the words "help his father win" and fell silent for the time being.

"I ...... I want Sakura, my younger sister, to return to the Tosaka family with the consent of her father and mother. ”

The smile that Lu Xiao had been hanging on his face paused for a moment, and his gaze became a little deep.

'Has Sakura's adoptive event already happened?' Sure enough, everything was Shi Chen's fault. ’

Basically determined the timeline at this time, Lu Xiao lowered his head slightly and assured Rin Tosaka: "This request is not difficult, even if you don't need the power of the Holy Grail, you can achieve it, Rin, please wait and see." ”

……

Lu Xiao vaguely remembered that Sakura seemed to have been succeeded to the Maki family by Tosaka Tokitomi a year before the Fourth Holy Grail War.

The Holy Grail system in Fuyuki City is jointly managed by the three major families known as the Gosan family, and every 60 years, the Gosan family will send members to participate in the war, hoping to fulfill the long-cherished wish left by the ancestors and complete the third magic heavenly cup.

The remaining 4 candidates are recruited from outside, usually giving a spot to the Magic Association's Clock Tower.

The three royal families are Tosaka, Machiri (Makiri) and Einzberen, and Lu Xiao's lord Rin Tosaka is one of the members of the imperial family.

However, this fashionable and young Rin has not yet taken up the responsibility of the Tosaka family, and the current head of the family, Tosaka Tokitomi, is still alive and actively planning how to win the Holy Grail War in the Tosaka Mansion and touch the vortex of the roots.

According to the information provided by Rin, it is still nearly a year before the Fourth Holy Grail War officially begins.

Tosaka Tokitomi has been preparing for the Holy Grail War for many years.

Taking advantage of the good relationship between the Tosaka family and the Templar Church's head of the Holy Grail War, Nginmine Rimasa, he secretly concluded an alliance agreement two years ago by accepting Father Ngami's son Kiri Ngami as a disciple.

The reason why Rin used chalk to draw to summon the magic circle was mainly to relieve the depression in his heart.

Each generation of the magician's family records their lifelong study of the family magic into the magic mark, which is the most important thing for the magician.

Each family will have only one magic mark, which is usually passed down to the best successors of the present generation.

The luck and misfortune of the Tosaka family come from this, as the mother of the bloodline inheritance, Zenjo Aoi is too good, and has given birth to two excellent successors who are qualified to inherit the magic mark.

From Tosaka Tokitomi's point of view, the family's magic seal can only be passed on to one person, and another child with excellent magic qualifications is destined to not get a complete family inheritance.

In the case of his own lack of strength, this well-qualified child is likely to attract the covetousness of some magicians, or even clock towers.

With this in mind, Tosaka decided to pass one of his children to the withering Maki family, and she would inherit the magic seal of the Maki family.

If he himself fails to win the Fourth Holy Grail War, the two sisters, who control the Kiriri and Tosaka families respectively, may be able to cooperate in the next Holy Grail War in 60 years, fulfilling the long-cherished wish of the Tosaka family.

"The starting point is good."

Lu Xiao, who turned on the breath, stood outside the very gloomy atmosphere of the Matong Mansion, and sneered sarcastically: "But you really know too little about the Matong family, Tosaka Shichen." ”
