Connor's Hogwarts

Chapter 293 Decryption, Fifth...

After that Quidditch match, Harry became the little hero of Gryffindor. Connor didn't expect Harry to catch the Golden Snitch so quickly. If he didn't know that Dumbledore was "just", Sna Pu is also "integrity", and Connor wonders if the old headmaster or the old bat cheated on Harry.

Gryffindor's house points were immediately ranked No.1, and the lion cubs were extremely excited. I wish they could still be so happy when Harry was deducted fifty points.
Connor remembered that around Easter, that is, after Hagrid's little dragon Norbert appeared, Harry and the others were each deducted fifty points
Although I don't know if things will follow the original track after the "plot" is messed up by a certain Connor, but Connor believes that as long as he is there, the plot will definitely not develop according to the original track.
Connor is so big, he has never seen a real dragon. If possible, he would like to raise one by himself. As for where to raise it...

I heard that there is a suitcase with a huge space, and the inside is a small world. It seems not expensive. It is about the price of two or three pieces of [Golden Paper] from Artoria.
Well, it seems that it is indeed a bit expensive, let's make one by ourselves after mastering the Untraceable Stretching Mantra.

Connor has been busy deciphering the fifth staircase recently, and he already has a clue
The west tower, the eighth floor, Connor is floating here alone. The word floating is used because he did not land on the floor. Connor is suspended in the center of the tower, with a drawing board floating in front of him.

Connor turned out to be floating in the air and drawing.

Even with the help of magic props, being able to hang in the air so easily while still painting stably is enough to prove that Connor's ability to control magic power has reached the level of subtlety.

Suddenly, Connor's hand holding the paintbrush trembled slightly, the earrings with the Deathly Hallows logo shook, and a figure appeared beside Connor.

"Eh? Why is it in mid-air?" Arturia ran out. She flew around Connor, looked at Connor's drawing board, and said, "Master, what are you doing?"

Connor turned to look at Artoria. Today, she didn't wear genuine armor, but a dark gothic long skirt—this is what she brought Alice's skirt to help him draw. .

Connor didn't know when she started to pay attention to her dress, but it was pretty good, although she could only look at it but not eat it, but at least it was pleasing to the eye.
"It's rare for you, Saber, to care about me. As you can see, I'm drawing, and I'm drawing the stairs here." Connor said with a smile.

"What do you draw the stairs for? Master, aren't you solving puzzles recently? Can drawing stairs help you solve puzzles?" Arturia has been indifferent to her old master recently, which is really negligent.

Connor shook his head: "As for the puzzle of the stairs, I think I've almost figured it out, and now I'm just waiting for the last piece of the puzzle."

"It's solved? How did you solve it?" Arturia froze, her face full of disbelief. Didn't she just follow her for a few days?Why did it suddenly unravel?Did I miss a few chapters?
Connor turned his eyes back to the drawing board, and said in a calm tone: "Actually, it's not complicated. Look at this staircase, it's an extra one, right? Since it appeared suddenly, it must be there too. Suddenly disappeared at a certain time..."

"Indeed it is"

"Then the question is, when will the stairs disappear? If I deduce the time when it disappears, will it solve the mystery?" Connor said with a smile:
"So, I guess, it's going to disappear at the end of February, and it's either 28 or 29 days before the new staircase appears."

"Eh? But Master, didn't you say before that the stairs didn't appear on February [-]st? How are you sure it will disappear at the end of the month?"

"That's because I didn't realize it before." Connor shook his head, with a little pride in his tone: "The stairs did appear on February [-]st, but it's not our February [-]st."

"?" Artoria looked at Connor in confusion, the hair on his head was curled into one?Number.

Connor laughed out loud looking at her dumbo, who had a sense of a dimensional wall being broken.

"Saber, do you know the [ten days that disappeared] in history?"

"I don't understand, I haven't heard of it, you haven't told me." Artoria shook her head, denying Sanlian.

康纳摇头晃脑，炫耀着他前几天才查到的小知识：“在现在世界通行的历法记载上，1582年10月5日至14日这十天是不存在的，在英国历史上1752年9月3日至13日这十一天也是不存在的，这就是著名的【消失的十天】。”

"why is that?"

Connor rubbed his chin, and slowly organized his words: "The calendar commonly used in the world today is the Gregorian calendar, which is also the Gregorian calendar, which uses the birth of Jesus as the first year of AD."

"Astronomy is a great science. Although I don't really believe in astrology, I have always admired the science of observing astrology to determine the time period. I always feel that I can look at the sun and stars 365 days a year. The man is amazing, well, I admire Conan very much."

When Connor talked about his interest, he threw the paintbrush aside and began to give Artoria a "science popularization":
"The calendar set based on the apparent movement of the sun is called [solar calendar]. The Gregorian calendar is a kind of [solar calendar], and on the other side of the continent, in a country called the Far East, there is also a set of visual calendars based on the moon. The calendar set up based on the law of motion is called [lunar calendar], these calendars are recorded by astronomers from generation to generation, and belong to the precious wealth of mankind.”

Connor boasted about his "hometown" before turning to the main topic: "However, our year is not 365 days, but 365.242 days. It is 365 days missing, so in the calendar, the remaining 0.242 days of the three years are given to the fourth year, and the fourth year will have 0.25 days, which is a leap year."

Connor raised his palms and bent his fingers one by one: "Repeat this cycle of 365, 365, 365, 366, the stairs below us must also be recorded according to this cycle, every four years, there will be more One day, this is what I guessed, the reason why this extra staircase suddenly appeared, as for why it didn’t just appear for one day but appeared for so long, maybe even lasted for a month.”

"I think it's probably because this is a [test], the designer still wants us to find it out, if it only appears once every four years, I think no one will be able to discover this secret in another 1000 years"

Artoria nodded thoughtfully, and then asked, "So what does this have to do with [The Ten Days Disappeared]?"

"I'm about to talk about it." Connor waved his hand and said, "Before the use of the Gregorian calendar, there was another set of calendars, which was the Julian calendar started by Rome in 45 BC. In terms of duration, people calculate that one year is 365.25 days, but a solar year is not exactly 362.25 days, but 362.24219...days, with a difference of about 11 minutes and 14 seconds per year."

"This error is not very large, and it may not matter at the beginning, but as the error accumulates year after year, this calendar is very out of sync with the actual solar year."

"So in the 16th century, Pope Gregory VIII made a correction to the calendar. Because by the 16th century, 11 minutes and 14 seconds per year had accumulated into 10 days, which added 10 days to the calendar. Then With a wave of his hand, the pope directly cut off the ten days."

Connor waved his hand and cut: "This is the origin of [The Ten Days of Disappearance]."

Artoria seemed to understand but half understood, Daimao turned dizzy and said, "That's why"

"So, when Ms. Ravenclaw set this set of laws of operation, the calendar used as the basis must not correspond to the current calendar. And we don't know what Ms. Ravenclaw used to set the rules. How long is the cycle in days, minutes, and seconds?"

Connor spread his hands: "Therefore, there will definitely be errors accumulated until today. This is the main reason why the dates do not correspond."

"So I think that the staircase appeared on February 28st and will disappear on February 29th or [-]th. This puzzle has been solved."

Connor made a final decision, and Artoria nodded repeatedly, indicating that she understood.

"So, master, you are now waiting for the last number 29?"

"Yes, at the same time, we need to record the movement rules of the stairs this month. There must be important information hidden in the complete rules." Connor picked up the paintbrush again.

"Although I think my guess is close to ten, I am still worried that there may be some mistakes, so I come here from time to time recently to have a look. After all, today is in the twenties, and the real [February] has already passed half Well, I'm not very relieved..."

"Oh..." Artoria felt that it was meaningless for her to stay here...

"Then master, please come on, I'm going to find someone else to play with..."

After finishing speaking, he disappeared into Connor's earrings with a whoosh...

"..." Connor's hand holding the paintbrush froze in the air, and the pride he had just shown off disappeared without a trace.

Sure enough...I'd better draw another obedient, considerate, gentle and capable paper figurine wife... Connor thought so...
