"Ahhhh Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo”

"It's noisy, shut up Uncle Ben, you stupid crow is in estrus."

In the courtyard sprinkled with silver-white moonlight, Wen Wenzheng flapped his wings in boredom and suspended in the air complaining, while Mei Hong, who was originally sitting cross-legged on the bench and playing a game, gave Wen Wenbao a murderous look at Wen Wen who disturbed his game experience.

"The moon is very unstable these days, even an old monster like me can't control himself, and there is no way to do it if the mood of the young Raven Tengu like her is a little strange, Sister Hong, you can be a little considerate."

Huiyin's face had an obvious expression of discomfort, and she looked a little unusually anxious.

"Hmph, the moon."

Although she has stepped into the category of the undead, but after all, Mei Hong is different from ordinary monsters, and she has no special connection with things like the moon, but because of some things in the past, she still maintains a certain complex emotions about the existence of the moon, no, it's not so much about the moon, but for someone who was born on the moon.

"Now, Wenwen, do you know how long the rotation period of the moon is?"

It was not so much to ask a question in order to get the answer, but to dispel the lingering sense of anxiety in the body and find a topic at random, Huiyin looked at the astronomical book in his hand and asked casually.

"Huh? What is the Moon's orbital period ......? This one. Generally speaking, it is twenty-eight days, but in reality it should be twenty-seven days and eight hours. However, because the earth is constantly revolving, the cycle from the new moon to the full moon is usually 30 days, but in reality it is about 29 and a half days. Feed! Even elementary school students with a little common sense know this kind of thing, right? ”

"Yes, the revolution cycle is not 28 days, and the profit and loss cycle is not 30 days, which is really interesting."

As if she had thought of something, Huiyin frowned and looked up at the bright moon that seemed to be unchanging in the sky.

The new moon was the first day of each month in the old calendar. Because it signifies the rebirth of the moon, the moon on this night is called the new moon. In the same way, the three days are called the three days of the moon, and the night of the fifteenth is the full moon, and the dates of the old calendar coincide exactly with the changes of the moon. Until now, human life has a very important relationship with the waxing and waning of the moon.

"Because the night of the first day of each month is a new moon, and the night of the fifteenth must be a full moon, so the tenth month must be thirty days."

"So what."

Wen Wen was not interested in perfunctory.

"However, the cycle of the moon is not thirty days. Therefore, in fact, the night of the 15th is often not a full moon. Don't you think that's a bit abnormal? ”

Hearing Huiyin's question, Wenwen also restrained her impatient attitude and thought about it, after all, she was a big monster no matter what she said, although she would be affected by the moon, she would never lose her mind.

"The night of the fifteenth should be complete night...... Could it be that someone deliberately mistimed this time? ”

"That's not all. As you just said, like the revolution cycle, the rotation period is also twenty-seven days and eight hours...... What is the reason for this? ”

After thinking about it for a while, even Huiyin couldn't get an answer that could explain it, and the question that was originally raised to kill the restless mood made people even more anxious.

"Forget it, it's not a big deal anyway, maybe someone thinks the accurate numbers are too boring, so they made such a prank."

"What kind of reckless guy would do such a thing?"

Wenwen slowly floated over and complained.

"Among the guys I know, there's a guy who would definitely do this kind of thing."

As if she remembered some unhappy memories, Mei Hong spat hard with an annoyed face.

meanwhile

After saying goodbye to Kanzaki, Murasaki did not go to sleep as she said, but changed into formal clothes and arrived in the courtyard of a rather powerful mansion through the gap.

"Ya Le, it's really unreasonable to be a guest from afar without notifying the host, but you have to entertain the precious guests."

Looking at the mature woman who was not surprised by her appearance, Purple showed a kind smile as if she had seen a friend.

"Can this kind of posturing intimidation be avoided, it's really boring."

There are not many people who can be indifferent in the face of the malice of the monster sage Yakumo Murasaki, even if they search the whole world, and the woman Yakumo Purple is facing at the moment is undoubtedly one of them. Although this woman is not technically a existence in this world.

The great sage of the moon capital - Eight Meaning Yonglin

Although humans know very little about the moon people, Yakumo knows very well how terrifying the woman in front of her, dressed in a strange nurse's uniform, leisurely trimming flowers and plants, like an ordinary doctor.

If the feeling of purple lies in the primordial fear derived from the unknown in her, then the feelings that Bayi Yonglin brings to others are probably the unfathomable wisdom that has naturally precipitated over a long period of time.

Hundreds of years ago, Yakumo Purple at that time was even more dangerous than now, although she had the terrifying power to play with the realm, but she did not impose any restraint on it, and she was ambitious to gather countless ground monsters, playing with the realm of illusion and reality, and jumped into the moon reflected on the surface of the lake to attack the moon.

-- As a result, of course, it was a fiasco.

The Moon Sage set a trap and used the Vault to adjust the moon's semi-revolution period from fifteen days to 14.8 days, so that the gap between the ground and the moon was compressed to the point where it was impossible to pass, and she was trapped on the moon surface even if she couldn't escape.

Purple, who was cut off from retreating, could only surrender obediently, no matter what, Purple was not strong enough to defeat the entire moon capital on her own.

It is for this reason that since then the month has not been divided equally into thirty days, and the earthly calendar has been disturbed. The people of the moon did not care about what the earthly calendar had become, and simply changed the law of revolution so that the fifteenth night would not coincide with the full moon. For the Moon People, the ground is just a place for them to look down, and they don't have to think about how the people live there.

The ground is just a huge filthy cage for them.

"Well, it's actually a blessing to you and the Moon King. If I hadn't met that kid in that state, I'd probably still be thinking about how to get revenge on such a boring little thing. ”

Zi raised his head to look at the place where he had suffered the shame of the only failure in his life, and the moonlight that was about to enter winter looked exceptionally innocent and cold. For youkai, the moonlight is several times more dazzling than the sun, and it can even illuminate things that are not usually visible.

In the ancient days when youkai and gods were wreaking havoc on the earth, on a night like this, youkai would follow the path of youkai illuminated by the moonlight to attack humans. The moonlight can make the eyes of the youkai see clearly, but the light is too dim for humans. In this way, humans can't see the night road clearly, and they can't tell whether it's a person, a monster, or a rock in front of them.

"The kid?"

Although she defeated Yakumo and the youkai alliance she led in the last Moon War, Yakumo's terrifying power and innate wisdom in that war were not only other youkai, but even Yongrin, the Moon Sage who established the Moon Capital with the Moon King, was deeply jealous.

Of course, what such a monster said would not be just chatting with himself, in fact, from the time Zi came here alone, Bayi Yonglin had already understood that the other party was not coming this time to be an enemy of himself, and he could even help if he used it well. In communication between intelligent people, language has never been a means of expression, but only an aid.

"It's a small and ordinary city, and it doesn't even have a name. Since he fled with Kaguya, why didn't he choose a more prosperous city or an extreme one to go to the deep mountains and old forests and chose this place. ”

Zi didn't answer Yonglin's question, but talked about some inexplicable words indifferently.

"It's an ordinary small city, but it's just a few train stops away from Tokyo's Akihabara, and next to it stands Mt. Yachigatake, which was once taller than Mt. Fuji, and is home to the two protagonists of the Great Battle of Suwa...... Why do you think that's why? ”
