PS: Xiaoice The reason for my cold is in this chapter.

————————————

In the hall of Boli Wuyu's house, Morisa, who was already dressed, and Lin Meng, who was yawning, plus a young girl, the three of them sat on the sofa in a neat and orderly manner, while the boy stood opposite them, next to a blackboard that he didn't know when he got his hands.

"Everyone has arrived...... [look around (ˉ-ˉ)?, look around again (ˉ-ˉ), and then look around again (⊙△⊙)!!? 】…… How come there are two people missing!? Paparazzi... What about Shotimaru and Sakura!? After looking around again and again, the boy was finally convinced that the person who was the least likely to be absent (demon?) And it turned out to be ...... Absence!!?

W-How is this possible!? Take the paparazzi ...... The style of shooting pills should be when he hears that something big is going to happen, he rushes to the scene as soon as he hears and shouts: I smell the smell of big news!! Honest and honest Shotmaru Bunsenshang!! That's right!! No, no, no!! That's not the point, the point is, why is Sakura absent!? As a good child who doesn't need to worry about himself, and can even be called "someone else's child", Sakura can't run out early in the morning to go crazy, and the first person to come to every family meeting is Sakura's ......

In the end, it was the girl who solved the boy's doubts:

"Eh~~ Nini, I just wanted to tell you about this," the girl raised her hand and whispered: "The moment Wenwen said she was going out to find the news, she went out early this morning, and Sakura was also dragged out by her, saying that she wanted to be a tour guide or something." ”

After speaking, he imitated the tone of the shooting pill at the time: "The moment I took this little girl out to look for the news, I came back at night, so I didn't have to look for us~~~"

Even the smirk on his face is vivid, as if he was the paparazzi himself.

“…… That's the case, hmm~~~ Although he was skeptical about the moment of the so-called news of the Shotmaru, but after all, it was a big monster, and Sakura shouldn't have anything to do with her protection, let's solve the problem of how to link Sister Marisa's door to Gensokyo...... "As he spoke, the boy turned around and picked up a piece of chalk and scribbled on the blackboard, as if he had completely forgotten about it.

But I'm telling you quietly, don't tell him: in addition to the reason he said, the main reason for giving up the search is that he is a road idiot, or a road idiot who only knows straight lines. You make a road idiot in a strange (?) Find two elusive people in a huge city, and if it's not the person who arranged it, it's the road idiot who is looking for his own death.

————— Small Theatre —————

The living room of an author's house,

A certain Yuelin suddenly appeared behind a certain author who was coding words, patted him on the shoulder, and said: Author, please come over.

Author: What's the matter? I'm saying in codeword.

A certain Yuelin: Don't ask so much, just come here.

Author:...... Okay, hurry up, I still want to say the word.

Then, an author who didn't know that his life was approaching got up and followed him to a door.

A certain Yin Yuelin [pointed to the door]: This is it, there are people looking for you inside.

A certain author [probe in]: Inside? Wow!! It's cold!! How could anyone be looking for me here......

Before the author's words were finished, a certain Yuelin behind him found the right time, kicked him in without saying a word, and then quickly closed the door.

On the opposite side of the door is a pre-linked space, and a snowstorm is falling.

A certain author [while shaking and slamming the door]: Hey... Y-What are you doing... Sneezing ...... Hurry up, hurry up and open the door... I'm now... Wearing... But... Ahh Short-sleeved... Ahh I'm going to die... Ahh

Yuelin: I'm sorry, I don't want to do that, but you know too much.

A certain author: I, I am a writer, an author... Ahh How... Possible... Ahh Know, know... No, not much... And also... Ahh You, your, and your character are... Ahh Righteousness, justice and kindness... No... Ahh Evil, evil, black... Quick, open the door... Really, really going to die...

Of course, a certain Yuelin has long since left, and the poor author in short-sleeved shorts stayed alone in the ice and snow, and soon collapsed from exhaustion, slowly covered, and his body temperature gradually cooled.

End of ———— Theatre————

Ignoring a certain author who was on the verge of death, and hearing that her door was once again "honored" to be selected as the carrier, Morisa couldn't suppress her "excitement" and said loudly: "Hey!! Why does it have to be the door to my room!!! ”

Of course, Morisa's speech was not noticed by everyone, and after a while, the boy drew two circles on the blackboard, one large and one small, and the small circle intersected with the arc of the great circle, part in the big circle and part outside the big circle.

After finishing the painting, the boy pointed to Madoka and said, "This is Gensokyo, and the big one is the world, and the approximate relationship between Gensokyo and the world is just like the graphics I painted, attached but with a certain degree of independence." ”

As he spoke, the boy thickened the arc of the small circle in the big circle with chalk, and continued to explain: "This is the great enchantment of Boli and the realm of illusion and reality, which is used to isolate the common sense of the world, and it is also the strongest protective shield, except for Sister Zi, almost no one or monster can break through this layer of protection (Otoyu Gong smiled and said nothing), this is also a problem we must face now. ”

"Basically, there are only two ways to travel freely through the Great Enchantment." As he spoke, the boy gently wiped off a part of the thickened line, revealing a small opening, and at the same time added a few lines indicating the inflow, and said: "The first is to forcibly make a gap on the top of the big barrier, which is convenient and convenient, but if you do this, the common sense of the world will also flow into Gensokyo with this gap, which will have a huge impact on Gensokyo's extraordinary knowledge, and may even lead to the destruction of Gensokyo......"

"So this method is unacceptable." After the young man finished speaking, he made a big cross on the gap, and drew an eye pattern in the middle with red chalk, and explained: "The second method is Sister Zi's gap, in fact, when I was in Sister Zi's gap before, I have already discovered that Sister Zi's gap is not a gap in the big barrier, but through an alternative teleportation space, using the back door to achieve the purpose of shuttling between Gensokyo and the outside world, this method is the most feasible for us at present, but there are three problems in doing so......"

The young man drew a question mark on the red line and said: "First of all, I don't want to trouble Sister Zi too much, I always feel that if I owe Sister Zi too much favor, the road will be difficult to walk in the future, secondly, we can't find Sister Zi all the time, and finally Sister Zi's personal wishes, as the manager and guardian of the Great Enchantment, I don't think Sister Zi will help us again and again, which is also unfair to other monsters in Gensokyo, so this path needs to be considered." ”

"Neither method works, it's basically nothing to do, but this is based on the premise of 'basically', since it basically doesn't work, so why don't we try the non-basic?" After speaking, the young man pointed at the girl with the chalk in his hand, "Xiao Ling has provided me with a very good and feasible method. ”

The young man drew a smaller circle next to the red eye pattern, which happened to connect the inside of the big circle and the inside of the small circle, and said, "Sister Lin Meng, you should still remember the time flow space that trapped me and Sanae during the academy festival, right?" This space may be because Xiao Ling forcibly transformed the structure of the space, and he got the control of the space in a vague way and became the master of the space. ”

"If you can imitate Sister Zi's method and use this space to connect Gensokyo and the outside world, then it will not only facilitate the passage but also avoid the corrosion of Gensokyo by the common sense of the outside world, after all, that space is an abnormal space attached to the world, and it will not be affected by common sense, and you can use the power of extraordinary knowledge."

"And my idea is to first link one side of the space to the door of the outside world, that is, the door of Marisa-san, and then after we return to Gensokyo, we will link the other end to the door of the shrine, so that the link of the space is complete. As for whether the space can link two places at the same time, Xiaoling has already tested it, and the answer is yes. After the boy finished speaking, he drew the left and right arrows on the small circle to indicate that he could walk with him at will, and then put down the chalk to indicate that I was finished.

The boy explained his thoughts very clearly, as long as anyone who knew a little bit was able to understand it instantly, and then in addition to the girl who had known for a long time, Morisa and Lin Meng lowered their heads at the same time, thinking about the success of this idea.

After a while, Lin Meng raised his head first and said, "Xiaolin, I think you still have a little bit to say......
