Connor's Hogwarts

Not changed yet

After that Quidditch match, Harry became Gryffindor's little hero. Connor never expected that Harry would catch the Golden Snitch so quickly, if he didn't know that Dumbledore was a "just" Snape. He was also "upright", and Connor even wondered if the old headmaster or the old bat had cheated on Harry.

Gryffindor's house score suddenly reached No. 1. The little lions were very excited. I really hope they can still be so happy when Harry was deducted fifty points...

Connor remembered that around Easter, after Hagrid's little dragon Norbert appeared, Harry and others were deducted fifty points... Although he didn't know what happened after the "plot" was messed up by a certain butterfly. Will it follow the original trajectory? But Connor believes that as long as he is around, the plot will not develop along the original trajectory...

Connor has never seen a real dragon in his life. If possible, he would like to keep one by himself. I heard that there is a suitcase with a huge space and a small world inside. It seems not expensive, and it is probably The price of two or three pieces of Artoria's gold paper...well, it is indeed a bit expensive. I'd better make one myself after I master the traceless stretching spell.

Recently, Connor has been busy deciphering the fifth staircase, 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 was actually floating in the air and drawing.

Although he used magic props, he was able to hover so stably in the air and paint at the same time, which is enough to prove that Connor's ability to control magic has reached a state of subtlety.

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

"Why are you in the air?" Artoria ran out, flew around Connor, looked at Connor's drawing board, and said, "Master, what are you doing?"

Connor turned to look at Artoria. She was not wearing genuine armor today, but was wearing a dark gothic-style dress. She took Alice's dress and asked her to help draw it. Connor didn't even know when she started to pay attention to her clothes, but it was pretty good. Although she could only look at it but not eat it, 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 are you doing by drawing stairs? Master, haven't you been solving puzzles recently? Drawing stairs can help solve puzzles." Arturia has been indifferent to her old master recently, which is really derelict in her duties.

Connor shook his head: "As for the puzzle of this staircase, I think I have almost figured it out. Now I am just waiting for the last piece of the puzzle."

"How did you solve it?" Arturia's hair flickered, her face full of disbelief. She hadn't been following for a few days. Why did she suddenly solve it? Did I miss a few chapters?

Connor returned his gaze to the drawing board and said in a calm tone: "Actually, it's not complicated to say. Look at this staircase. It's an extra one, right? Since it's a sudden staircase, it must be somewhere. Time disappeared."

"Indeed it is..."

"Then the question is, when will the staircase disappear?" Connor laughed: "I guess it will disappear at the end of February. The time when this new staircase will appear is either 28 or 29 days."

"Hey, Master, didn't you say before that the staircase didn't appear on February [-]st? How can you be sure that 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 stupid hair on her head curled into a number.

Connor looked at her silly hair and laughed out loud, feeling as if the dimensional wall had been broken: "Saber, do you know the ten days that disappeared in history?"

"I don't understand, I haven't heard of it, you didn't tell me." Artoria denied it three times.

Connor shook his head and showed off the little knowledge he had just found out a few days ago: "In the calendar records currently used in the world, the ten days from September 5th to 14th do not exist. In British history, September 1752, 9 The eleven days from Sunday to the 3th also do not exist, and these are the famous ten missing days.”

"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 this science of observing stars to determine time periods. I have always felt that people who can look at the sun and stars 365 days a year It’s amazing, well, I admire Conan too.”

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 motion of the sun is called the solar calendar. The Gregorian calendar is the solar calendar. On the other side of the continent, in a country called the Far East, there is also a set based on the apparent motion of the moon. The calendar is called the lunar calendar. These calendars are recorded by astronomers from generation to generation and are precious treasures of mankind..."

Connor first boasted about his "hometown" and then turned to the topic: "But, our year is not 365 days, but... days. That is to say, if we count it as 365 days in a year, , 0.242...days are missing every year, so in the calendar, the remaining 0.25 days of three years are given to the fourth year, then the fourth year has 366 days, which is a leap year."

Connor raised his palm and flexed his fingers: "Repeat, the cycle of 366. The stairs below us must also be recorded according to this cycle. In less than four years, there will be an extra day. This is what I guess, this The reason why the extra stairs appeared, and why it didn’t just appear for one day but for so long, maybe even a month..."

"I think it's probably because this is a test. The designer still wants us to find it. If it only appears one day every four years, I think no one will discover this secret in another 1000 years..."

Arturia nodded thoughtfully, and then asked: "So what does this have to do with the ten days of disappearance?"

"Isn't that what I'm about to say?" Connor waved his hand and said: "Before the use of the Gregorian calendar, there was another set of calendars. The Julian calendar was introduced in Rome in 45 BC. , people calculate the length of a year in days, but a solar year is not exactly days, but 9 days, and the difference is about seconds every year."

"Because the error is not too big, it may not matter at the beginning. However, year after year, the errors accumulate, and the calendar becomes out of tune with the actual solar year."

"So in the 16th century, the then Pope Gregory VIII made a correction to the calendar. Because by the 16th century, every second had accumulated to 10 days, which meant that there were 10 more days on the calendar. The pope made a big hand. Wai, just cut off these ten days."

Connor waved his hand and said, "This is the origin of the ten days of disappearance."

Arturia seemed to understand, and her hair was spinning so fast that she felt dizzy: "So..."

"So, if the calendar that Ms. Ravenclaw used when she set this set of operating rules must not correspond to the current calendar. And we don't know what Ms. Ravenclaw used when she set the rules. How many days, minutes, and seconds is the cycle..."

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