As a result, the common front between the four seasons and Illya and others was temporarily formed.

Later, Illya also told the four seasons about their situation, and in general, it was about the same as the development of the original.

Rank cards suddenly appear in Fuyuki City, and Rin and Ruvia are ordered to recycle them, only to be discarded by Ruby and Sapphire, while Illya and Miyu are chosen to carry out the recovery work in their place.

However, there are some differences, such as the fact that the Servant is not in the mirror realm like in the original game, but will suddenly appear in the present realm.

As for the rest, they didn't know much about rank cards.

After a brief exchange, everyone was ready to leave.

"What a headache."

Before leaving, Rin glanced back at a mess of woods.

The mystery cannot be known to ordinary people, and the battle between magicians must be avoided by others, and this trace of destruction also needs to be dealt with, and Rin, as the manager here, has an unavoidable responsibility.

"I need to go to a place to investigate before I leave."

Before leaving, Shiki said.

“？”

Everyone stopped because of the words of the four seasons.

"I'm going to investigate the underground cavern where the Great Grail ≦."

As the heart of the Holy Grail War, the four seasons are a must-visit, and knowing that the enemy is nearby, it is imperative to know the situation as much as possible. And that kind of place would be very bad once it was captured by the enemy, so Shiki didn't plan to wait even a day, even after a continuous battle.

"The Great Grail? But there's nothing left there. ”

Rin said to Shiki.

"I'd like to investigate the situation of the spirit veins if I can, so I'd like your help."

Investigating the four seasons of the spirit veins can be done alone, but it will be more efficient with the assistance of the Tosaka family with the help of the manager. Now that the alliance has been decided, there is no reason not to take advantage of it.

"Well, I see."

Rin thought about it for a moment and agreed.

After making a decision, everyone set off towards the Great Hollow, Shiki only needed Rin's help, but the others followed.

This time, there were no more accidents along the way, and they came to their destination smoothly.

It wasn't far from where they were, but it wasn't affected by the battle, so there were rows of trees around it.

Flying over the woods at night, the four seasons use their abilities to lift up those who can't fly.

"If only it could be so smooth."

Luvia, who was gently covering her dress with her hand, said.

"yes."

Rin also rarely agreed with the other party's opinion.

The road to the Great Hollow is hidden in the dense woods, a narrow crack in the mountain wall that only one person is allowed to walk through.

The people who fell to the ground rushed in and walked in through the four seasons.

As soon as you enter the interior, you can feel the cold aura of the cave, and there is no sign of life activity in the complete darkness.

The four seasons light up the surroundings, and you can see that this is a passage with no traces of artificial carving, and the average person would never imagine that there is a huge magic ceremony place inside.

The passage is very long, much longer than the one that comes across from the outside. As the space deeper into it began to grow, the view finally widened after a few minutes of advancement.

It's underground, but it gives the impression of a vast plain.

Shiki didn't feel the breath of people here, and it didn't seem to be preempted by the enemy.

Walking to the center of the hollow, sure enough, just like Rin said, there is only an empty plain here, and the huge magic array that should have stored zài no longer exists.

"What are you going to do?"

Rin followed Shiki and asked, "Investigating the spirit veins in general requires specialized equipment, but she didn't see it.

"You just need to be there to help me."

After letting Miyuki and the others stay away from the center, Shiki stands in the center.

He took out a round hand mirror from his bosom, the one he had previously obtained in Gensokyo.

He placed the Mirror of Nitokris on the ground as Shiki leaned down and pressed his hands to the ground.

Then, with the four seasons as the center, there was a reaction around it, and the magic that had gathered in the Great Hollow began to work according to a certain pattern. Countless paths of light appeared around the four seasons, and after a series of complex combinations, a magic array with a radius of hundreds of meters appeared in the center of the Great Hollow, illuminating the nearby space.

"What!?"

"How is that possible!?"

Rin and Ruvia's voices came from near and far, and among those present, who knew the most about magic, they could see what Shiki had done at once, and they were the most shocked.

"Huh? It looks so powerful. ”

Although she didn't know the specifics, Illya was amazed by the sheer momentum.

"This isn't your average awesome, Illya."

Ruby said to Illya, and then Ruvia, who was next to them, explained to the group.

This kind of magic is close to ritual magic, and generally requires a large number of ritual materials to be prepared in advance, as well as a few bars of chanting. But he did it in an instant.

"Oh."

Everyone nodded cooperatively.

"It takes a lot of magic to streamline the process, and I would use a metaphor for it to consume double-digit gems."

By the time Luvia explained to the crowd, the seasons had entered their second phase.

"Miss Tosaka, please input your knowledge of the spiritual veins here into the magic array.

"Okay."

Rin is also a great magician, and Shiki only needs a few words to explain before she understands.

"That's it."

As soon as Shiji's words fell, he saw that the mirror of Nitokris, which had been placed on the ground, suddenly floated into the air, and the magic array was in operation, and the path of light began to flow back. When the light of the magic gathered on the mirror, it emitted light from the mirror, and a three-dimensional topographic map appeared above the mirror, which looked like a stereoscopic projection.

This is the image that the four seasons have presented with the help of part of the function of the mirror of Nitokris after exploring the spiritual vein.

Shiki beckoned everyone to come over and present the results of the investigation to everyone.

"It is unexpectedly possible to present the entire spiritual vein in such a complete way!"

"And it looks much more accurate than rubbing...... Wrong! It's not a photo, it's a real-time video! ”

Rin and Ruvia's exclamations came and went.

"What does that mean?"

Illya looked at the dense lines of different shades in the image, and she was already dizzy.

"That's what the veins look like, Eliya. Those lines are the channels through which the magic flows. ”

Ruby further explained.

"Shiki, you're okay, right?"

Miyuki walked over to Shiki and asked.

"Huh? Tired or not? ”

Hatsuzakura's hand kept groping Shiki's body, as if to check his body.

"No problem."

Shiki replied in order not to worry them, but he saw that Miyuki and Hatsuzakura were sighing, and it didn't seem to work.

"How so?!"

At this time, Rin's voice suddenly came out, and Shiki looked over to find that Rin was looking at the stereoscopic image in surprise, and Luvia next to her had the same face.

The images of the zuò made by the four seasons can be said to be both comprehensive and straightforward, so even magicians with some knowledge can understand it, so they must have noticed that there is an unexpected problem in the spiritual veins of this winter wood city.
