“…… You're such a scumbag. After a moment of silence, Rin Tosaka said with an indignant expression on his face.

The meaning was obvious, and she agreed to Lin Yiyan's proposal. Immediately, Lin Yiyan, who received the reply, did not toss Yan Fengqi Li anymore, and as soon as his mind moved, he withdrew the spatial ability exerted on him.

The next moment, Yan Fengqili's body loosened, and his body stumbled a little uncontrollably. Obviously, because of the relationship of excessive struggle before, he deviated his center of gravity at the moment of breaking out of the restraints, and the balance of his body was destroyed, but it was not strong, and in the eyes of outsiders, he returned to normal and stood firm again with just a slight flick.

"Looks like I'm no longer needed here." Yan Feng Qili glanced at Lin Yiyan with an indifferent expression, then turned his head to look at Rin Tosaka on the side and said calmly.

"Hmph." Rin Tosaka snorted softly. Turn your head to the side.

"Then I'll take my leave." Yan Fengqi retracted his gaze and said. Without pausing, he turned around and walked towards the library, disappearing into the staircase leading to the outside in a moment. Then Rin Tosaka glared at Lin Yiyan viciously, and after leaving a warning of "don't break the book", he also left the library.

Lin Yiyan, who saw the two leave, shrugged his shoulders, walked to a bookshelf again, took out a magic book from it, took it in his hand, turned around and walked to the sofa on the side, sat down and opened it, lowered his head and continued to look through it.

And from this day on, Lin Yiyan and Rin Tosaka entered a similar library that temporarily belonged to Lin Yiyan. Lin Yiyan is not allowed to appear in the mansion on the ground at will, the two sides do not interfere with each other, one party appears, the other party must retreat, etc., and live together in the Yuansaka mansion.

It wasn't until more than a month later that Lin Yiyan, with the help of Jarvis, recorded all the books in Tosaka's house into the neural connection device.

…………

Looking different from usual, Lin Yiyan, who was still in the library at this time, and Rin Tosaka, who was about to come to the library to practice basic magic, couldn't help frowning, but he didn't say anything. Instead, he turned his feet and prepared to leave the library.

It's just that before she could make the trip, Lin Yiyan's voice suddenly sounded in the quiet library.

"Wait a minute, Rin." Rin Tosaka paused. Without looking back, he said in a cold voice, "I said, we don't know each other, so please call me by my last name when you call me." ”

"Okay, Tosaka." Lin Yiyan shouted helplessly.

"What's the matter?" Rin Tosaka said indifferently.

"I'm ready to leave. So from today onwards, you can go back to the library and study. Lin Yiyan stood up from the sofa and looked at Rin Tosaka, who was standing at the entrance of the passage, and said.

"Really? I thought you were going to be lazy in my house for the rest of your life. Rin Tosaka turned. looked at Lin Yiyan sarcastically with a mocking expression.

"Well, that's a proposition worth considering." Lin Yiyan's expression was shocked when he heard this, and he looked at Rin Tosaka with a thoughtful look and said. Rin Tosaka's expression froze, and a nervous expression was faintly revealed on her beautiful little face.

"Heh......" Lin Yiyan, who took in the changes in Rin Tosaka, smiled, and continued to tease her, "Forget it, let's wait for you to be a big one." Although you already have the appearance of some beauties now, but your figure is a little worse after all, if you want to have breasts or breasts, if you want butts without butts, it is really difficult for people to arouse too much interest. ”

"You!" Rin Tosaka, who was evaluated like this, was stunned, glared at Lin Yiyan angrily, gritted his teeth and shouted.

"Alright, I'm leaving, we'll see you later." Lin Yiyan ignored the anger and sharpness in Rin Tosaka's eyes, and said with a smile. Then he moved and walked towards the entrance of the passage. Rin Tosaka, who was in the middle of it, didn't move, just stared at Lin Yiyan with his eyes wide open, and then let Lin Yiyan pass by him, and gradually faded away with the slight footsteps, until he couldn't hear anything.

"Damn fellow!" After a few more moments, Rin Tosaka said with a gritted tooth.

On the other side, Lin Yiyan, who had left the Yuansaka Mansion, still did not leave Dongmu Town, but turned his footsteps and walked towards the Liudong Temple, the heavy spiritual land of Dongmu Town.

And this process didn't take him much time, that is, ten minutes, Lin Yiyan arrived at Liudong Temple. Then I met with the presiding officer of the temple, and with 100,000 yen of incense money, he rented a room from the presiding officer of Yanagidong Temple and temporarily lived in the temple as a traveler.

After a day off, he began to digest the contents of the Tosaka family's collection recorded in the nerve connection device, and also sent some of the materials of gem magic to Intix, Ossola and Sakura through interdimensional communication.

It's just that the result is not very good, at least the content of the records in the Tosaka family's collection is not of much use to Lin Yiyan's original purpose - to find the back door of the Holy Grail system, which makes Lin Yiyan a little disappointed.

But if you think about it carefully, although the so-called Imperial Three Families refer to Tosaka, Einzbelen, the original Mariqi, and the current Makiri family, there are actually only two of them who really participated in the making of the Holy Grail, or who made great efforts in the process of making the Holy Grail, both the Einzberen family that took out the main body and part of the results of the design of the Holy Grail system, and the Makiri family who made the Servant system. As for the Tosaka family, apart from providing a venue and supporting a spiritual vein as the power source of the Holy Grail system, they have not contributed anything else to the Holy Grail system.

Therefore, unless it was the manipulation of the spirit vein, some of the secret contents recorded in the Tosaka family's collection were not of great use to Lin Yiyan, who was preparing to use the spirit technique to summon the heroic spirit in violation of regulations.

"In other words, do you still have to start with the Einzberen family, or the Maki family......" Lin Yiyan, who spent a few days and carefully and quickly browsed the contents of the Tosaka family's book collection, muttered to himself.

"It seems that I still have to meet the insect master again." After thinking about it, Lin Yiyan thought about it, got up and left the fasting room, and left Liudong Temple and moved towards the city center. In just half an hour, Lin Yiyan came to Dongmu City, which is across the river from Dongmu Town, entered its city center, and found the largest jewelry store in the city and walked in.

"Welcome." The greeting greeted.

"Show me the biggest, best gems you've ever had." Lin Yiyan, who walked straight to one of the counters, said like an upstart.

"Uh...... Okay, you wait a minute. The clerk was stunned at first, and then quickly responded politely. Then he turned and walked to a small door not far away, and disappeared into the doorway.

Then about five or six minutes passed, and the female clerk appeared in front of Lin Yiyan again. It's just that this time, in addition to her, another man with a dress and temperament that was obviously different from that of an ordinary clerk came over and stopped in front of Lin Yiyan.

"Hello this gentleman, the manager of my main store - Tomohisa Yamashita." Without waiting for Lin Yiyan to ask, the man introduced himself. Then he asked, "Excuse me, are you sure you're looking for the biggest and best gem?" Got no other requirements? ”

"Yes, as long as the color and purity are high enough, it doesn't matter if it's wool stone." Lin Yiyan nodded in affirmation.

"Okay, then sir, please come with me." Yamashita Tomohisa glanced at Lin Yiyan carefully, nodded, and stretched out his arms to invite. Lin Yiyan didn't say anything, followed the other party out of the counter, walked to the small door not far away, and then walked through the small door, entered the VIP room not far from the manager's room, and sat down on the sofa in the VIP room.

"Sir, please wait a moment." Yamashita Tomohisa said, and then left again, leaving Lin Yiyan alone.

However, time still didn't make Lin Yiyan wait long, and in just over two minutes, Yamashita Tomohisa returned to the VIP room with a small wooden box accompanied by a security guard, and sat down opposite Lin Yiyan.

"Sir, this is the biggest and best gem that we have in our store, take a look and see if it meets your requirements." Tomohisa Yamashita opened the lid of the box with his hands, revealing the contents of the road.

In an instant, an irregular ruby that was about two-thirds the size of a baby's fist and its surface shimmered with magnificent light under the light appeared in Lin Yiyan's eyes. Lin Yiyan's eyes lit up slightly, and he nodded lightly.

"More money." Lin Yiyan said very simply.

"Five hundred and eighty thousand yen" Tomohisa Yamashita, who heard Lin Yiyan ask the price, secretly breathed a sigh of relief, and said sincerely with a smile on his face that he didn't know how many times more sincere than before.

Late at night, in the fasting room of Liudong Temple.

While the temple owner's family was all sleeping, and even for insurance, he deliberately used anesthetics for secondary treatment, Lin Yiyan took out the ruby he bought from the jewelry store at a large price during the day and held it in his hand. followed by a gaze, and the spiritual power swept by.

Suddenly, he saw that the ruby form in Lin Yiyan's sight had changed, from the original red real solid, to a pile of strange molecular accumulations made of carbon molecules, which squirmed slightly and stopped between his fingers.

Then Lin Yiyan released the nano machine, and through the direct control ability of the mind provided by the IS system, he controlled the nano machine to fly into the ruby that although it had become a molecular polymer in his eyes, it still maintained its material form in the real world, and attached to the edge of those carbon molecules little by little, and then with a move of his mind, with the power of the nano machine, he controlled the displacement of the carbon molecules little by little, and transformed the ruby in his hand.

This process is very slow, and it needs to take into account several issues such as the overall structural characteristics of the gemstone, natural polymerization, and purity improvement, so it is not until more than ten minutes have passed that the adjustment is completed.

At this time, the ruby shape in Lin Yiyan's hand changed again, from the original irregular form to an oval, quail-like egg-like shape, the surface was crystal clear and reflected with bright light, but the quality was greatly improved before!
